There is a lot of novels like that, not only one.
For some reason a lot of Chinese fantasy novels involve a person reincarnating and then beating the shit out of everyone else. It's a generic form that almost everyone follows.
I hope not, harem ruined tales
It's either being sent back to younger self, or having god's luck and finding an item (with or without super powerful spirit inside) that allows them to cultivate several times faster than others. :P
Yes.. there tons of that type
yea it's just like the isekai genre all the stories are kinda the same but with their own little tweaks here and there
the story is copying from the Tales of demons and gods story, the main character died, travel through time because an item, in his previous life the heroine died trying to save the main character.
