Reincarnation? I'm an Old Hand at This

Alpha male lead + feel-good power fantasy + secret identity revealed and amnesia + reincarnation setting + everyone has special powers = reincarnation? I'm an expert at this!

One night during his junior year, the "hero" Wu Ni sees an unbelievably awful web series adapted from a novel. Furious, he opens the comments, only to find everyone discussing the original novel instead. The next day, he wakes up lying on the ground. What is going on??

After living here for a while, he seems to realize that his memories aren't real. He never got into college at all; he's always lived in a small village. His memories have turned his happy family into a single-parent household. Yet he doesn't seem worried, leisurely wandering through 7,000-plus cycles of reincarnation?

Then the arrival of an old teammate changes everything. Was she the one who caused his amnesia???

After everything goes wrong, Wu Ni resolutely embarks on another cycle of reincarnation. His memories seem to grow hazy. Who is he?

"I want to create a happy world where no one dies."
