Well, Tempokai did something else. He actually made me read it as well. I'm sorry, but I won't do the usual feedback, it takes too long. And Tempokai voiced a lot of good points that I agree with. Your novel is bad. It's not a 'this isn't my cup of tea' but a somewhat objective bad.
Reason for why I dare to utter the word objective is quite simple. It has bad grammar. We can argue that pacing is subjective, we can argue that characters are subjective, plot is subjective, etc. We can't argue about grammar. It's either good or bad. Yours is bad. Not terrible, but in combination with bad prose, your paragraphing, choice of words, sentence structure, usage of dialogue and action tags, and so on, it is even worse.
And if we dismiis the fact that story parts can't be objectively bad, I would once again agree with Tempokai and add that those parts are also bad. There is also a lot of small logical mistakes that all ties into the characters and plot.
I will do just one example.
"I trusted Lin Fan… I helped him steal the Dust of Destruction so we could escape together, but in the end, he left me here to face this fate."
Maybe I'm blind, but not once did she comment on the fact he has changed after that. She knew him, but when MC appeared she treated him as this weird mixture of already knowing the new Lin Fan, and not knowing the new Lin Fan. It honestly doesn't make any sense.
It doesn't make any sense that MC's past as a person from Earth doesn't play any role in the plot, and is only featured in the first few paragraphs. Might as well make him someone native to that world, like an old and evil cultivator who hijacks a young body for himself. Nothing would've changed. Well, I guess you couldn't have made him enjoy his 'newfound' power, but honestly, it won't make any difference in the grand scheme of things. It only changes a couple of words here and there. Like when he is surprised or whatever at how easy it is to take life, you just delete the surprised part, and nothing changes. It's still 'evil' guy.
Ahem, you can brush the point above, but here's what will really hurt you once you finish reading it. Crazy lunatic like no other... I'm sorry to say this to you, but your story is banal or generic, whatever word you prefer. It doesn't stand out among translations and original works. There is no unique spin, and I'm sorry to say this, but the grammar doesn't allow me to say it's better than others. Again, even if we close our eyes and pretend like plot, characters, pacing, world, and so on are all subjective, you still lose when compared to other works. Because your prose and grammar are worse. So your story isn't even a classic that has been done well.
And this leads me into a question that will hurt you. Why should a reader read your story? Let's pretend I am a reader who really likes this type of stories, reincarnated or transmigrated or whatever as the villain in a cultivation. Why should I read your story and not other ones? It's the same stuff, but worse. Honestly, the only answer I can think of is, I will read your story only when there is no more similar stories to read.
Another question that will hurt you. Why should a reader spend their money on your story? You might think I'm just dumping on you here or making fun, but this is a legit question I want you to ask yourself. Because I see nothing wrong with this desire to earn money through writing. I'd like to do it myself. But we should look at it objectively. Let's pretend once more that I'm one of those readers that like this type of stories. Why should I sub to your patreon, and not sub to DDL that translate I Am the Fated Villain? You might think, why not sub to both? The answer is, not only people have limited budget, there is also more than I Am the Fated Villain you are competing with.
Another person made a good point. You can and probably will do better at WN. Maybe you will even earn some money there if you sign the contract, which I don't recommend doing, but it's your decision ultimately. The problem with WN though is that it's a different type of competition there. You should produce your chapters at least daily. All year round. It's better if you do two chapters a day. Can you do it? I personally don't know, and don't need the answer. It was a rhetoric question.
The only good part I can point out is super subjective. There is no system. I hate system. They are the epitome, the creme of the crop of bad and lazy writing. So here I can say you did good. The bad part of this praise is, as I said a subjective nature of it. Because people on WN don't hate systems, so it's not even a realupside. ?
P.S. I read a bit past Tempokai.
