I Am the Source of the Uncanny

This protagonist isn't the source of all the supernatural phenomena; he clearly learns skills by killing them. And "source" means origin, so the title implies that killing the protagonist will prevent all supernatural phenomena from appearing in the world. What's the point of this lousy protagonist being alive then? Just grab some damn evil fire and blast him with it!

That's incredibly stupid! You believed the supernatural being when it said it had a symbiotic relationship with you?! Don't you have some kind of cheat code? Just kill it and absorb the supernatural's essence, and its abilities will still be yours. This is so ruthless!!!

Is this really written by the author? The subject matter is good, but the writing style is poor. And the protagonist seems rather useless.

The author is ruthless; not only did they abandon the story, but they also made readers pay money to see a terrible ending.

No way, author, you just love making the protagonist suffer, don't you? Being possessed by the mirror ghost was bad enough, but now this? If you're going to write a tragic story, just say so at the beginning! What happened to the invincible protagonist from the "Strange People's Inn" story? Seriously, this is ridiculous. You're really good at turning readers away.

Skillfully adding books to the bookshelf, skillfully waiting for updates, then skillfully discovering abandoned books, and skillfully removing them from the bookshelf.

The plot is alright, watchable, with some flaws, but the major flaws are too obvious. The mirror ghost replacing the protagonist is a bit jarring, but still somewhat acceptable. However, the original owner's consciousness replacing the protagonist is just disgusting.

Write a fantasy novel, featuring a senior disciple, powerful family connections, and villains. Just easily brute force your way through the story and you're done.

Hopefully, this won't become the source of eunuchs. 🙂

It's short and weak, I just hope it won't be abandoned.
