MC was born with a demonic heart, that caused him to lead a different life with split-personality when he was younger. By the time his Systemic power starts up and he regains his own consciousness, he's already in his 20s and stuck in a villain role.

Gu Changge was plotting after the Human Messiah, a reincarnative entity that descended whenever an Absolute Negative Sky (my own lousy translation) Calamity also descended. They effectively represent absolute "good" and "evil" respectively. These two forces have battled through the ages, and the MC is after them both.

As part of his scheme, he captures and manipulates Jiang Chu Chu to reveal the whereabouts of both these entities. There's r*ape involved, which is disappointing and very pointless. The only lame defense Gu Changge makes to Jiang Chu Chu is that he's "just trying to survive, like everyone else", because Human Messiahs have always exterminated Demonic Art Successors like him.

Lawful Evil: These characters believe in using society and its laws to benefit themselves. Structure and organization elevate those who deserve to rule as well as provide a clearly defined hierarchy between master and servant. To this end, lawful evil characters support laws and societies that protect their own concerns. If someone is hurt or suffers because of a law that benefits lawful evil characters, too bad. Lawful evil characters obey laws out of fear of punishment. Because they may be forced to honor an unfavorable contract or oath they have made, lawful evil characters are usually very careful about giving their word. Once given, they break their word only if they can find a way to do it legally, within the laws of the society. An iron-fisted tyrant and a devious, greedy merchant are examples of lawful evil beings.

Chaotic Evil: These characters are the bane of all that is good and organized. Chaotic evil characters are motivated by the desire for personal gain and pleasure. They see absolutely nothing wrong with taking whatever they want by whatever means possible. Laws and government are the tools of weaklings unable to fend for themselves. The strong have the right to take what they want, and the weak are there to be exploited. When chaotic evil characters band together, they are not motivated by a desire to cooperate, but rather to oppose powerful enemies. Such a group can be held together only by a strong leader capable of bullying his underlings into obedience. Since leadership is based on raw power, a leader is likely to be replaced at the first sign of weakness by anyone who can take his position away from him by any method. Bloodthirsty buccaneers and monsters of low Intelligence are find examples of chaotic evil personalities.

1st is mc's fiance, she's a female protagonist from the future, well I kind of understand why MC doesn't kill this one because she has use and really loves him.

NOW 2nd female character is mc's cousin who, mind you MC DUG OUT HER BONES. MC just talks to her and she's yeah he's kinda not bad. It's only later on that MC digs out the bone and gives it back to her like its a f*cking glove. Well, now one more girl in the harem I guess.

Then there is 3rd girl, this one is a f*cking masterpiece. She goes to meet MC and finds out his greatest secret well maybe 2nd greatest since 1st secret is his system. Just happens that she's dumb enough to go into mc's house and meet him openly even though she suspected something might be really wrong with MC. What did she expect? Well now MC has her in his grasp and can kill her whenever... but he needs information about a new son of luck. How? you may ask; well according to MC by taking to her and using his CHARM (hmmm... reminds me of EVERY protagonist ever) Later on its revealed that 1st girl already knew about the new son of luck and MC knows she knows... then why keep the 3rd girl alive since she's dangerous and if she reveal mc's secret the world is gonna be against him you may ask....i don't know go ask author ¯_ (ツ) _/¯. So when MC effortlessly kills son of luck who is revealed to be THE HUMAN ANCESTOR (REN ZU) he guess what.... he releases the 3rd girl and lets her go in the world with his secret and says that she won't reveal it because he's confident of his "effect" on her. (spoken like a true protagonist with his charm as a whole plot armor in itself) . Behold a new harem girl.

And btw why are every male characters depicted to be s*upid and idiotic? Even the human ancestor is like -100 iq. Like he's supposed to have reincarnated soooo many times and be the most ancient one.... did he not f*cking learn anything all these year.

In this novel all female characters are harem material and never killed and all male characters are potential food for MC.

Well I dropped and gave this novel a new chance 3 times now, this time I think I'm done with this novel.

his true identity is a true ancestor from the source world (the Strongest and highest world) his transmigration and the system is an arrangement by his true body, his ultimate Goal is to swallow the other 2 true ancestor and surpass his current cultivation

The problem is the translation. I don't know what the f* happened over the years or why there are so many translation groups for this, nor do I know why not even a single one of them manages to do the job right all the way. But let's just pretend there are only the three translations displayed on novelupdates, demonic translations, divine dao library and fantasy world online. I don't know much about demonic translations, because they didn't translate that many chapters so I wouldn't read their translations.

What I read after comparing chapter 1 of divine dao library (DDL from now on) and fantasy world online (FWO from now on), was FWO's translation. It read pretty decently and was fun and energetic enough, while not being that great in grammar all the time, it wasn't bad enough to be an eyesore either. It was translated good enough to be worthy of being called a translation without throwing sh*t at the original, names and translations were clearly relatively accurate. After chapter 150, however, that changed. The translator stopped and someone else there picked it up, suddenly the quality did a huge nose dive and after checking much later chapters, the old translator never returned. Suddenly, the dialogue felt weird, flowed badly, had worse grammar and completely lacked the "energy" and "liveliness" a novel like this should have. I still felt like giving it a shot because I like the novel, and for 50 or so chapters after 150 it read good enough, but after that it got way worse. The quality became very irregular, sometimes good enough to read but for most chapters it was horrible, as if the editor just up and spontaneously disappeared.

Very bad flow, huge grammar issues and clear mistranslations, titles started to often seem like machine translations as soon as the quality got horrible (which happened at chapter 200 that had the title "Husband ab*ses her for a while as she chase her husband's crematorium, I completely misunderstood him", which makes absolutely zero sense, haha. Makes you wonder if some girl chased a building with body incineration furnaces) and the chapter content's translation wasn't much better, some examples would be "Gu Changge personally explained what happened back then, and even dug up the bones to return the sister, no matter what happened in between, so that Gu Xian'er could not raise her hatred for him", "Gu Xian'er smiled sweetly, revealing a pair of shallow pear eddies", "if zhao tianxing's father had not interceded this zhao tianxing would have been beaten badly, and it would have been difficult for him to get off the ground for several months", "In any case, they came to escort, even if there was no credit, they still spent a lot of time and energy. But it was not to get a good look from the other side.", "You still have a chance to leave here while I am not angry right now", "This woman was beautiful to the extreme. such empty valleys and orchids, clear fog in the forest, very dusty, there was a quiet and moving beauty". So, I dropped the novel knowing it would just be a waste of time and energy to read more after 26 more chapters of horrible quality and fluctuating garbage quality which showed signs of getting even worse (checked 10 chapters ahead of that point and it was even crappier). They butcher the fun of reading it with such crappy english, too bad because a transmigrator female that also talks about chapters and clichés was just about to appear and it would've likely been very fun to read about.

Then I checked DDL's version at that chapter and after trying a few chapters, I once again confirmed just how utterly worthless their translations are and that it's a persistent issue all the way through. They systematically change almost every single ability and location name, sometimes even conjuring up nonsensical names with no basis (that might not even be english at all, chuunibyou much?), they also actively censor words or entire paragraphs, making the work very stale and lifeless. They practically parody the entire story by changing things actively, to the point where you question if they have any respect at all for the source work or author. Last time I checked, a translator needs to keep to the original meaning and story, just adapting some things slightly to mean exactly the same thing in english and make it easier to understand. But they change things to the extent that the story changes and it reads like crap. They have a, at first glance, good level of english, but the english they use doesn't fit a novel format at all as they often use rarely used or out of place english that would be more at home in education essays than a novel format, sadly the grammar and flow is nowhere close to being worthy of higher education either, it has tons of issues even if it looks decent at first glance. This fixation on "fancy" yet often inaccurate and out of place english instead makes it lifeless, flawed and dull to read, it barely even reads as a novel. It feels like they're tooting their own horns by trying to show off their english knowledge even though they're clearly not that good in the first place and the level of editing is not at the level of liberal but just not even correct anymore on any level. I really despise their translation, so sadly there wasn't any other options but to drop this otherwise pretty good novel so early, it really makes me sad.

Who the hell translates destiny points/value as "fatum", fortune points/value as "fortuity", black as "onyx", golden crow clan (which is a very typical race in this kind of story) to golden raven clan, daoist immortal palace to skyward schloss, transcendent bones as absolute detachment bones, leaving out various parts of names like "black heavenly eagle clan" becoming "black hawk family" or "ancient immortal gu clan" becoming "immortal gu family". Then we have wonderful sentences like instead of writing "Damn it! How dare you come to our territory and kill our people! You are courting death!", they write "curses! how insufferable of him to kill people in our territory!". They also changed "they roared with anger and hatred since even their own clansmen were here! The dead must be avenged" into several sentences of completely made up text, namely "they yelled vexedly as if they were growing insane. Some of them were even letting out deafening shrieks. Given how there were members of the victims' clans and factions around, the dead would definitely be avenged." See how incredibly awkward it reads? Not only do they conjure up fake content, it's also extremely cringeworthy to read. It flows choppily and the english used is ill-fit for the purpose. As translators they should respect the author and their work and they should also have the awareness that they suck at writing dialogue and descriptions, so how about sticking to the script? This isn't some theater improv. The worst part is that they do this several times a chapter at least, you see why they're probably one of the worst "translators" out there? Even the new translator at fwo after chapter 150 still translates things pretty accurately and doesn't change things randomly. Oh, I gotta mention this one as well, just to show how bad their translation can get. They translated "Once these two ancestors are under my control, the entire black heavenly eagle clan will effortlessly fall into my hands." as "Once I gain control of these two ancestors, the Black Hawk Family will all be mine. Easy peasy, lemon squeezy.". It almost made me god damn cry how moronic that sounded, they changed his entire personality for a lame joke as he's not the kind of guy who would say crap like that, not to mention he didn't even say "easy" or anything close to it, they just made it up. Go write your own damn novel if you want to write whatever you feel like and make things up.

Also, not sure what the f* FWO is thinking, but their site is a hot mess, utter garbage from a design standpoint. I say this after having taken many game design and art design classes over several years with a player (user) -centric standpoint. It's a mess to use, it's as if they've done everything in their might to restrict and bother their readers, which is simply counterproductive. I had to get an addon just to be able to right click and have my mouse cursor change depending on where I hover it, but even then their text is locked behind idiotic code that makes it impossible to select it, not that I care much about selecting text, I just hate sites that disable right click and other options. They made any interaction with the site impossible without modifying the code or getting addons. Changing cosmetic things like color, font etc is also very difficult thanks to this. As if that wasn't enough, they cram in various floating buttons and when you scroll down, you get a huge banner of "next" "previous" and other sh*t options, but at the bottom and top of the page you find these options anyway. Also disruptive yellow boxes before the "next chapter button" in every chapter about donations and so on, which gets really annoying to repeatedly see. I had to use an adblocker to remove all the bothersome elements. One of the worst sites I've ever seen, but at least usable if you block the crappy elements.
