Mysterious Divinity

This is my first time writing a novel, because I like Cthulhu + SCP elements, but this genre is very niche on the Internet. I read one book after another, so I decided to start writing it myself. The writing style may be relatively immature, so I hope everyone can give me more opinions. The protagonist is reborn into a world with all kinds of weird creatures and old gods. While constantly strengthening himself, he uses his talents to create mysterious objects one after another to explore the truth of his abilities and at the same time find a way to return to Earth. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
