The Daily Task of Preventing My Disciple from Turning to the Dark Side


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

As the number one pill alchemist of the immortal world, Mu Chen had always believed that it was because he had single-mindedly focused on concocting pills that led to him to neglect disciplining his disciple. Which in turn, caused his disciple to be led astray by the seduction of devil cultivation, leading to the three realms to fall to disaster.

After his rebirth, Mu Chen resolved to properly teach his disciple, give him the very best resources, earnestly love him, carry him close to his heart, teach him by way of example, and didn’t let him grow corrupt.

Sure enough, his disciple became more and more “intimate”. Every day his disciple even crawled into his bed, rubbing against his chest and clinging to his thigh. It was just that his expression isn’t exactly quite right……

I debated whether or not I should write this, but I figured I should at least offer a warning to those who, like me, may feel really cheated and angry over the future developments in this novel.

This starts off quite cute and fluffy at the beginning. There's a lot of humorous interactions, though from early on, you can tell that ML's very yandere. He'll only get worse.

On the other hand, MC is likable, and honestly, very pitiful as well. His only wish was to properly raise his disciple to be... more>> good now that he was given this 2nd chance, but from the very beginning, that was an impossible dream. He deserves someone much better than ML.

Below are spoilers for why this is tagged with r*pe and why I absolutely despise ML:


MC gets drugged w/ an aphrodisiac during a fight while ML's in the middle of retrieving the sword he used in his previous life. MC then gets news that ML might be in trouble, so ignoring the fact that he's poisoned and that rushing back would agitate his poison more, MC still selflessly flies to where ML is as fast as he can.

MC helps ML from descending into madness, and ML returns to his senses. I have to stress this: ML is 100% within his right mind at this point. MC then asks ML for the panacea antidote MC gave him before, and what does ML do?

ML refuses, and proceeds to r*pe MC instead.

And that's not even the worst part. After MC wakes up, he realizes that while he was compromised, not only did ML r*pe him again and again, but ML also forced him into signing a death marriage contract. The contract can't be altered, can't be erased, and all of its terms were completely dictated by ML alone.

I don't know what you guys consider a fluffy romance, but this is furthest thing away from that for me. To be honest, the kinds of methods ML was using before this to get MC to agree to be with him were already straight up emotional manipulation/abuse. And then literally a day after MC (reluctantly) agrees to be with him, ML r*pes MC like the scumbag that he is.

True love? Yeah, right.

All I can see from their "romance" 2/3 of the way through this novel is that ML has zero respect for MC, doesn't care at all about MC's feelings, and chose his own s*xual gratification over MC's well-being.

I can't remember a single instance in which ML chose MC over himself. All of his "doting" is founded on the basis that it doesn't inconvenience or go against his personal goals/desires. Not once has he sacrificed anything for MC, and even his "sacrifice" last life was b/c he knew he could go back in time and reset everything, which makes it not a sacrifice at all. ML doesn't treat MC like a lover; ML treats MC like a favored toy.

Forcing MC into a permanent death pact completely against his will, is not love. Threatening to destroy the world unless MC always stays by his side, is not love. Kidnapping the only relative on MC's mother's side who cares about MC and never allowing them to meet again out of petty and completely unfounded jealousy, is not love.

That's just some of what ML has done, and it finally culminated into MC getting r*ped and forced into a permanent bond that's not much different from those s*ave collars you often see in fantasy isekai. Except this one can't be removed, ever. MC now literally has no other option but to stay forever w/ ML. No autonomy, no choice, no respect.

Some people might like this kind of abusive relationship. I don't. Some might even argue that it gets better in the last 1/3. But to me, a "romance" that's founded on forced coercion, blackmail, and r*pe is just a Stockholm Syndrome tragedy. ML is irredeemable as far as I'm concerned, and I regret reading this so much.


The only reason I didn't give this a 1 star rating is that the beginning was enjoyable, and it really was quite cute. Too bad that couldn't last. <<less

I find it so funny that there are so many people getting angry over ML forcing MC. Did everyone somehow forget that he is a complete yandere, born half a devil and destroyer of the three realms? Compared to that, him waiting for 20 years and confirming their relationship before he forced him is already a great virtue for someone like him. If everyone is outraged about the consent issue, what about all the physical abuse the MC inflicts just because he doesn't want to be forthright? It's... more>> not really about what's right or wrong for them. This is how their relationship works. The author never said he's a good guy so judging ML by normal standards is s*upid. Also, someone alleged that all the sacrifices ML did in his previous life were void because he knew he could turn back time. I'm like... did we even read the same book?! He certainly didn't know beforehand! He did everything possible and ran ragged to turn back time for his shizun. If that doesn't give him obsession issues, I don't know what will. (Oh and this is not a spoiler. It's explained in the first few chapters.) Both of them have issues and they deal with it over the course of their relationship. ML did r*pe him but after going through a trial that literally affected his state of mind. You want a yandere to be a goody two shoes after that? Go read a fluffy romance then. Don't read books that have tags of yandere and r*pe and then complain about it.

P.S: Unconditionally spoiling someone, thinking they are the most attractive person and agreeing to be in a relationship with someone is not an indicator of love? MC is not s*upid. He just loves his own disciple and is in denial. Even so, Mu Chen doesn't appreciate anyone whining about him needing saving. He can take care of himself because he's just that powerful!

Ok, now that I'm done with that, I really enjoyed reading this book. The ML is deliciously manipulative. Hahaha. He's such a scawy devil even at 5 yo. It's cute! And then, he does everything possible to cuddle with MC as a cinnamon roll and is all, 'I'm a cutie pie. I'll do anything you say.' in front of the MC. Hahaha. It was hilarious. And he bullies all of MC's pets and his junior brothers and pretty much everyone else apart from the MC. Lol. The world building is very good and the MC really is very tsun tsun. He spoils ML unconditionally and thinks he is very attractive. But he confines himself to the role of a master and is not willing to be confront his own feelings. He's such a proud little shou. But he punishes ML because he doesn't want to face his complex feelings and it really got on my nerves sometimes. However, they make it work. I guess in their world, no one else would accept them so completely apart from each other. <<less

Made a mistake with the star, wanted to give it a two lol. Dropped the book; and I must say I'm upset that I have to drop this book because I tried my best to enjoy it and wait till I truly find the missing pieces that made me unsatisfied but... Gosh... I guess the book isn't for me as everyone else had enjoyed it.

I enjoyed the first dozens chapters of the book, it was all soft and fluffy while the disciple tried his best to become a bratty... more>> young boy while knowing his master will dote on him despite all the mistakes he had done.

The worst part is, he grew up being even brattier, more possessive, self centered and ignorant of his Shizun's feelings. He used the opportunity to get dotted on despite knowing that his Shizun had also reincarnated. He demands for things out of his selfishness and jealousy, all for mere petty reasons that includes the outer world.

We get it your Shizun is cold and aloof, yet he is still a palace master is he not? Does he not have obligations in the sect at all?

The MC does not only dote on his disciple, he also spoils him rotten to the point that he treats him like a princess and it's not a problem, not at all! But he doesn't at all treat the ML like his disciple and his attitude contradicts and changes all the time. He is inconsistent to the max. (yet the ML STILL thinks his Shizun loves him in that way, boy...)

His disciple bites him, gropes him, touches him sexually and yet all he does is look ahead and feel pity for the ML for not receiving enough love and guardiance when he was a child, , , , DAMN MC! HE'S A GROWN ASS BOY AND YOU DONT EVEN PUNISH YOUR DISCIPLE THAT MUCH! It's been years, move on!


There was a chapter when the Shizun spoke to the ML to treat his future partner or crush with respect and loyalty ; if he can't make them stay they have to try hard to keep them by his side. He also added that if they don't want to stay, the ML cannot force them to.

Yet the ML ignored all the good things the Shizun had said in the three full pages of quotes and only took the part where the master had said; to keep your beloved by your lside no matter what or among those lines. And he mentioned along with torture.

And he did EXACTLY just that.

How can you r*pe someone you love? Force him to marry you? Regardless of the situation, two way consent is very much needed.

And to think after raping him, his master beat him up, the ML dares to say.

"It's your fault. It's because you were poisoned and attached yourself to me. You must take responsibility!"

I was so shaken I wanted to cry and I just dropped the book immediately. He didn't have to say that, why didn't he show any remorse? How could he blame his teacher? How could he not have the slightest bit of respect to his Shizun?

Why does the r*ped victim had to take the responsibility? It's not cute and it's not funny at all. The scene was traumatizing and upsetting and I hated the scene so bad.

And to think the Shizun didn't even say anything despite knowing that his disciple was putting the blame on his shoulder, was just plain s*upid. Mu Chen lacks so many common sense it annoys me from the first chapters of the book.


The MC's only consistent attitude is his s*upid opinion and spoils towards his disciple. The ML is an as*hole and self centered, only thinks for himself. d*ck first brain later??

Ah... My review isn't fully trust worthy because this is based on my comfort and my opinions. How the character behaves, to the r*pe scene, and the change of heart muchen has after getting r*ped... I don't know. <<less

This is very unique and brilliant. A must read masterpiece that would make you stare at the screen lamenting the spares chapter carelessly dangling in front of you.

The story as yet to reveal its main course but it is already promising good stuff.

Even the characters are much satisfactory.

... more>> So far this is how far I have gone through the available translation (? I wish I could learn Chinese faster enough to read the raws) :

Both the two protagonist went back a hundred years from their death.

It is pretty tragic how they were tricked by the sect people.

Mu Chen was a genius in his sect (totally didnt pay attention to any mention of the sect name) and he was pretty obsessed with alchemy to the point of being shut in his palace isolated from the sect happenings so he was unaware of the other people's ill intention towards him coupled with his seemingly indifferent cold exterior he was easily misunderstood and nobody bothered to get close to him.

His discipline Gu Yunjue (i dont know if I got it right) was the only one close to him and he was the one that reversed time for them to go back together. He had a bad childhood. His mother would abuse him and his father that did not care about them had ten sons and threw him to the sect. His mother killed by his father. He only cared of his master Mu Chen even to the end when he betrayed the sect and became the Demon King. He still came back to Mu Chen who was on the brink of death caused by the sect and he tried to save him.

I wish for more updates to come in the future!? <<less

OMG I CANNOT!! >///<

I read this for a second time already, but d*mn Gu Yunjue is still so cute whenever Mu Chen is around. I also got this tingling laughter when I realized that Mu Chen didn't even know that his little disciple was already black and that Gu Yunjue was only cute to him.

I recommend this novel so much.. Come on, Read it. Go ahead, no need to be shy... We're all fujoushi/fudanshi here (or still converting (๑‾̀◡‾́) σ»)

The only thing I don't like here is the long duration of updating. Please I'm a desperate reader here!! I also can't read chinese (-_-")

I love the plot and the story itself is intriguing and fun! Hehehe a black belly disciple who deceives his master so that he alone could have all of his shizun's affection. I think that it's one of the best yaoi that I've read so far! The thing that I love so much is that the master which should be the uke is not the clumsy and adorable type but rather the "I am cold but with a warm heart" type.

And he could also fight and defend himself. It has... more>> so much potential. Please continue translating this work. &Lt;3 <<less

Sister upstairs who gave this novel 2 star, you almost deceived me with your review ah! >.<

Luckily I already read some of the translated ch so I decided to MTL this novel. Well it's true that the relationship between MC and ML is somewhat forced in the beginning. I expect nothing less from a Yandere character. But hey, it's not that bad, trust me. ML still respect and cherish MC y'know. And MC loves him too, he's a tsundere by nature so.... yeah... their love is kinda awkward. Some ppl... more>> like sister upstairs might think that this kind of relationship is toxic and unhealthy. And I know this novel is not for everyone. But oh well... all's well that ends well~ for me I have no complain hahaha.

Tbh it's quite hard to mtl this novel. I think I missed lots of details, and I don't really like the ending bcs I think it could be more. Don't worry it's a HE.

Overall it's a cute read. Not extremely good nor really bad. <<less

Read this in Chinese a while back and I am so glad someone decided to translate this is English.

A really heart warming yet cute story about the disciple and master. Disciple is a little devil and the master is a little slow-cute. Interactions between them are fun to read. Pace is a little slow, but not too bad.

Highly recommended!

Edit: I finally ended up dropping this series. The master is too clueless/clueless distracted and the student is too over-powered and in control of everything. All of the side characters are completely two-dimensional. You might enjoy reading this if you just want to see the student flirt and sexually harass his dense master in every single chapter, but after a while it really felt nonconsensual, and it just went from cute to creepy for me. Also, everything comes too easily, there is no plot or strife, just one guy who... more>> knows everything and one guy who knows nothing despite reincarnating.

There aren't enough chapters for me to write a full review, so I'll update this again later on. It may be a while since the translator changed and they're starting the translation over again from scratch.


Alchemist Mu Chen's disciple became a devil and the enemy of the world. Mu Chen is blamed for teaching him poorly and killed, only to see his estranged disciple sacrificing himself in an attempt to save his life... and then Mu Chen is transported back in time to his younger self. He takes in his disciple again and is determined to raise him properly in this lifetime... Little does he know that his disciple has brought back memories of the future as well.


So far, this series hasn't had a very strong start -- not bad, but nothing that really captures your attention. The writing style could be more exciting. It's like there's supposed to be some sort of emotion, but I'm just not picking up on it. I was also hoping that the tone of the series would either be light-hearted and comedic, or very emotional, but it doesn't seem to be able to make up its mind and it's sort of in the bland middle.

I am hesitant to judge the personalities of the main characters. The main character, Mu Chen, is cold and tactless despite his decades of experience. I think he's supposed to be "lovably dense, " but so far I'm baffled by how he isn't more subtle with his attempts to change the future. His disciple is just yandere (and that's it).

For now, 3 stars. I'll review this again when more chapters are released. <<less

Loss many brain cells trying to mtl this. Luckily, I found the Vietnamese translation and read from there. Don't be fool by a low review (to each their own, but see spoilers for my explanation). I'd say 4.5 for now since I haven't finished the novel. The story is very fluffy. I like how both Mu Chen and Gu Yunjue are very protective of each other. I've read to ch 68 after the not so pleasant part and still find the interaction between Mu Chen and Gu Yunjue hilariously adorable.

... more>>

Prior to the non-consensual part. Mu Chen was already rather protective of Gu Yunjue and would get jealous of his friendly interactions with other people. He's a bit slow and quite stubborn so he doesn't admit his disciple has a rather high place in his heart.

Mu Chen starts to feel different towards Gu Yunjue when he followed GY to the secret Realm to retrieve the GY's sword inheritance. He gets sucked in into some unknown portal with GY dashing into it with him without thinking of the possible peril. Mu Chen's heartbeat becomes erratic when he realizes how much GY treasures him to be able to dash into a space that reduces their capabilities into mere mortals.

Fast forward, he gets poisoned with an aphrodisiac. He can only live he engages in the deed with someone or takes an antidote. GY has the antidote but he's been repressing his urges for too long and decides to take advantage of the situation. While Mu Chen's mental capabilities are impaired GY initiates a death marriage contract where if one dies the other follows. Can't agree with GY's action here. Although, Mu Chen does seem like a guy that you need to push to make some progress. GY's kisses didn't work so I guess the author thought r*pe would help make some progress. GY only initiated the death marriage contract to make sure Mu Chen doesn't shrug off what happened. This dispels Mu Chen's intent to give GY a drug to wipe his memory of the event. GY did not demand that Mu Chen be with him or else he'll wreak havoc in the 3 realms as far as the current plot goes. Mu Chen did not agree to be with GY after a day. They continue to travel for serval months with some awkwardness to find the cure for Mu Chen's spiritual backlash. No smut scenes at all yet. The story didn't turn dark as Mu Chen and GY do cherish each other very much.

As for the Mu Chen's kidnapped uncle Chen Mo: GY kidnapped him to prevent him from telling Mu Chen GY's real identity. There's a pothole here so didn't get the full details but he eventually follows one of GY's minion to the Devil Realm to live freely from Chen family's responsibilities. GY is a yandere so its good enough he didn't kill Mu Chen's relative.


For those of you willing to lose brain cells with the mtl, ch 66 and 67 duplicate prior chapters in the original for a majority of the Chinese sites I've searched. You can try to mtl them from the Vietnamese title: Mỗi Ngày Đều Phải Phòng Ngừa Đồ Đệ Hắc Hóa. <<less

Always grateful for translating efforts; I know that I would not be able to undertake such tasks.

However, the quality of translation went so terribly downhill that I found myself going from reading, to scanning, to skipping, to giving up.

... more>> Really became more of a chore than a pleasure to read.

As for the content itself, I only held out until ch. 49. At this point, MC and ML have a cutesy relationship with a lot of humor stemming from totally different interpretations of interactions. Too bad that I just don't have it in me to slog through such a messy translation: ( <<less

The story is good. The plot progression was a bit slow. NSFW scenes were so little, but the kissing scenes were more abundant lmao. Nevertheless, the sweet and fluff moments gradually took me away.

The ending is quite rushed..? I wanted to see the side story between side couple 1 Duanmu and Hanzhi even if just 2 extra chapters :' (Same for the side couple 2 Tianyi and Yue :' (The ending didn't feel like an ending at all. :/ And I think Mu Dong and Jing Ting would... more>> become a thing in the future and I'm kinda looking forward to it.

In the end, the Mu side family didn't recognized Gu Yunjue fully so I'm kinda hopeful to see how will Gu make them give them their blessings as a couple.... ah it's kinda disappointing it ended abruptly.

This novel was fairly decent and had an interesting premise up until the MC and ML got together. After that, it really started to drag and I can understand why the author rushed the ending.

MC at first glance appears to be your typical cold mountain of a master, but he's actually a little fireball. ML, on the other hand, is sly and conniving. This leads to many funny interactions in the beginning as MC tries (and fails) to raise the adult ML who is trapped in a child's body. As... more>> a couple, hmm... I wouldn't say they have the healthiest of relationships. MC isn't good at expressing his feelings so he takes it out on ML by kicking, punching, and pinching him, although ML allows him to.

Things really started to derail after MC and ML got together because essentially there really wasn't much left to do. Yeah, I suppose the author could have explored MC's identity more or showed what happened to the side characters, but it seems they didn't try and just ended the novel.

If you're going to read this, I suggest staying away from Flying Lines and waiting for another translator to continue this because there are many parts of the novel that are mistranslated or just outright wrong. <<less

It was an ok read, I liked that even though the ML is said to be a yandere he never has hurt the MC in any way and has only angered him. He acts like a spoiled brat and is really possessive but the most important thing to him has always been the safety and happiness of his master. As for the Master (mc), he is such a tsundere it's funny, even though he won't admit he loves the ML he is as possessive as his disciple. The ending was... more>> happy which was good but a bit rushed, the translating was ok but I was confused about some things because of the way it was written, it would be good if someone acted as a beta and made it easier to read, but I have seen worse.

A xianxia novel with an intriguing couple: an archetypal yandere (GuYunJue) and an archetypal tsundere (MuChen). Both are perfect representatives of those classic, anime-style dere-types. With these extreme personalities, it is obvious their romance will not be ordinary and this novel is definitely not for everyone.

If you are looking for fluff and romance, there is none. If you are looking for smut, there is none (except a little bit at the end). But if you are looking for an unusual couple, who are constantly bickering, fighting and teasing each other... more>> about who is more powerful, superior and stronger, then you might like this story. There is no fluff, but the love between them is undeniable and unquestionable.

Others complain about their ‘evil’ nature... lol... Please consider that GuYunJue is an evil entity more familiar with mass murder than lovey-dovey romance and MuChen is a anti-social belligerent hermit, more often seen hugging his isolated mountain, or (literally) kicking guests from his home, or collecting fluffy spiritual beasts babies (and kicking them out when they grow up not fluffy enough lol)... yeah... both are not ‘nice’ characters... what? Did you expect a devil or an anti-social tsun-tsun to be nice?

Some will complain about r*pe, unhealthy relationship, stockholm syndrome bla bla bla... MuChen suffering from stockholm syndrome lololol... So ridiculous it’s funny... This is a fiction about a devil god and a taoist immortal! How on earth does real-life drama enter this story? In this couple, I see no submissive, no weakling, no victim that needed to be saved. If you so wanna see drama where there is none, it’s delusional, but up to you. <<less
