After Signing in for a Hundred Years, I Became the Peerless Immortal Emperor

I read the first chapter, Big Poison, and the main character's perspective is too crooked.

The first two films of Toxic feel like the protagonist has no brains. It's the kind of story where the protagonist is pretentious and has no brains. The outlook on things is a bit different from that of normal people.

The first chapter always feels familiar.

I feel like this protagonist is a bit narrow-minded. He just traveled through the body of the original owner, and was told on the same day that he (he is the original owner, not the protagonist) hooked up with the woman and wanted to dump him. And a teenager can understand the problem. He had several years of experience in modern society in his previous life, so he should be very mature in how to deal with people, right? Why does this feel like that of a junior high school student who has not yet left school? Such childish thoughts, and in a fantasy world, if you have no ability, is it not normal for others to abandon you? Strength is greater than anything else. It is normal to downplay the weak and praise the high, even in modern society.
