MC is transmigrated into this world (like most story does) and he found the young boy, Mo Shulin, also future Demon Lord, came into his place to seek shelter. Bai Yuming realized it was the Demon Lord and decided "Eh, why not, both of us will die at the protagonist's hands anyway, so let's just have a good time together." Bai Yuming is s*upid and unreliable because the world he used to live in and the world he's currently in, have different common sense. Bai Yuming was never meant to be a master, never meant to be a reliable elder and that's the fun part, seeing a modern, dependant on his mother college student suddenly became an elder that has power and status with no one to help him.

Bai Yuming also knew he's not meant for this job but he tried his best for his little disciple, wanting to teach Mo Shulin that being a demon cultivator isn't always a bad thing. He knew Mo Shulin hated himself when he was a Demon Lord. Mo Shulin is ashamed being a demon since he thought that his whole existence is an embarassment to his family, and Bai Yuming wanted to change that view, wanted to give his 10 yr old disciple a safe place to live in by not being bullied in the outer sect like his last life.

That's what I like about him, he'd do anything to let Mo Shulin live comfortably and not let him be wronged (though he's a very useless elder) but the thought also counts. There's one part where Mo Shulin cried, fearing his master would leave him but even though Bai Yuming doesn't understand Mo Shulin's thought, he still stayed there and comfort the already broken and battered young Mo Shulin.

Bai Yuming also gave Mo Shulin an advice regarding love and possessions. There's one chapter where Yan Qianqian and the slag scum were fighting and claimed it was love, Mo Shulin agrees to the point where love is about not wanting to share their lover to another, wanting their lover for themselves and don't want their lover to see others but Bai Yuming told him it wasn't love, but possessiveness. Love was meant to be a beautiful thing and an experience that would let you feel happiness all over but if it only made tou felt trapped and caged as if there's a chain holding you back, then it's not love. And there's where Mo Shulin realized his feeling towards Bai Yuming was something similar to a kid wanting to protect their beloved toy from other people touch and sight.

And in the secret realm, both of them spent their time together, it's very cute and honestly made me felt "Hey, maybe this is not so bad after all."

like killing demons for money to buy his house. He said he can't do it, but didn't even secretly try. The story already said he can fly really fast, so I doubt location/timing/secrecy is the problem.

And oh my god, the house issue made me so mad. Cause he looked through his purse and knows he has ZERO money. And what does he do? Buys possibly of the most expensive houses+alterations.

Then the next plot point is about the ML and MC having to do jobs, which brings in the previous point. And just further highlights the incompetency of the MC to even sit still and not break the things that the ML has done.

and there is no system or punishment for no following the plot line, so why don't the MC just up and go live somewhere far away, the plot literally says he's going to be r*ped and made into a scarf, like? They do say that the world is smaller than protaganist halo, but that is a really weak point imo, like who told you, it's not like you experimented right? (Atleast idt he did)

Though he didn't know much about the world he's in nor cultivate but he's trying his best for the ML and it's stated that he wanted the ML to accept himself as a demon cultivator, ML hated himself for falling into the demon path and MC thought when ML was in his child body, MC could at least give ML a better childhood but he didn't expect ML got reborn. MC is actually wise regarding feelings and other things since he gave ML a love advice after they met Yan Qianqian before entering the secret realm.

Yes MC is cowardly, st*pid and lazy but some of us also have his traits too, but even with all of this, MC is willing to appease ML and try his best to fix the mechanical rats he broke. That's why I like Bai Yuming, even if most of his hardwork is for him to become lazier, but when it comes to the people he cares about, he wouldn't hesitate to do it. Bai Yuming also shaves all of his precious rabbit furs just to save ML from his coma, it was so heartwarming to me

So MC ignores ML in the beginning, but later (when another disciple joins them) ML realized MC is the type that needs time to adapt to new situations LOL.

When they were in the fairy realm, ML was going through the final test where he was answering questions and he fails at the last step because even though he admits he loves MC (3 times!), his love isn't the pure unselfish kind (and MC is oblivious of course, just kindly comforts him and tells him it's okay that he failed).

So their feelings progress nicely (not too slow though :)) ML, who already realizes he wants MC as a taoist companion, gets aged up by a grandpa supporting their love from the fairy realm lolol and also that arc was sweet because MC was in a glitchy illusion of modern times so he knows it's fake but he's enjoying himself because he misses wifi and technology - at this point ML finds him and is confused at first but they somehow have an impromptu date. Dw they're pretty much already have an unintentional marriage contract at this point LOL)

It's also a cute healing story of MC being heaven's gift for the rebirth ML. :3

And the ending was something I should have seen coming it was a really good ending (bittersweet and happy ending) which wraps up and concludes the plot nicely

I'm upset at the fact that Xiao Yu, their disciple died, and the mushroom grandpa never came out and interacted with him. Xiao Yu had a difficult life, and his death was so upsetting!!!! It was one of my favourite moments seeing Xiao Yu and the gramps get along so well with each other, and how he had progressed after being given a chance. But they never met in reality, and Xiao Yu died in mushroom gramps' realm. : (

It's also upsetting that Shangguang Zhu qing had to experience his love ones die in front of him.

But it was nice knowing that Yan Qing Ling and the original BYM got married in their next life. YQL said that he probs never really love BYM, but he still decided to commit su*cide due to the emotional pain and found BYM in his next life. That was so wholesome!

I think the main reason people think he's s*upid is bc he doesn't know how to do many things like fighting and making artifacts which I think is kinda realistic since he didn't get the memories of the previous owner otherwise he does have some moment where it's showcased that in some situations although he knew that a person is not genuinely nice to him he decided to ignore it in some situations

It's also that he knows how unhelpful he is and he is accepting that he is kinda unreliable in many situations compared to the ML
