A warp in space-time occured because of the Space-Time Demon Spirit Book, and Ni Li, who should have died in an ambush by God-rank Demon Beasts, awoke to find himself sitting in a classroom. He had returned to his 13-year-oid self. Everything had been reset. How will he protect his true love now?
The anime is the worst thing that they could have done to the story. I am a big fan of both the manga and the novel and was so happy when I saw they were doing an animation. But with poor animation choppy scenes and even worse voice acting I am sad this was made. And it says something that the voice acting was the best part about this. I still love the story and will continue to read it but this is an abomination and I do not recommend it at all.
I am personally not sure why many people seem to dislike the animation. in comparision with the manga it is indeed inferior to it, but that doesn't matter. the manga is really good, and i'm exited every time there is a new update. the animation is not that bad, the intro is fantastic but maybe a little too long given that the episodes are 7 minutes, and they still made the opening 1 minute 30. the episodes are a little cringey (and i missed some scene's) but i think that is what makes the animation pretty good. altough i would like it if the episodes where a little less short...
Not bad, it's a bit bad on episode 1, but the story slowly progresses as it was in the manga nad novel. The concept of rebirth and having all your past knowledge into your new reborn life is basically broken, especially on the mc's situation where he had over 200-300 years of wisdom from his past life. Only thing I don't really like is the short episodes, but they make multiple episodes a week, so I guess that makes up for it. Its ok so far, but I would like it go faster and possibly catch up with the manhwa(chinese), then maybe the novel :p. if you want to find out more about it then ofc there's always the manhwa and the novel. I recommend the novel over the manhwa, because the manga skips some details(basically every manga/manghwa). the novels interesting to read, but since mad snail fudged up the novel I think so he basically gave up on it, but he still writes out chapters but like on a basis of once a month :(
