(TL;DR: author doesn't know what he's doing, story contradicts itself too much, it isn't self aware)It's quite bad, the author is worst at keeping his story consistent than I was when I was lying as a toddler.MC is Op AF, and that's ok but he contradicts himself too much.First of all: MC supposedly is an elder with more than hundreds of years old, but thinks 15 years to reincarnate is a long timeMC goes against a guy who is way out of his league, just because he ain't gonna bow before "a kid with a hundred years" and some medium level compared to his old self.After that MC who doesn't give a F about the strongest guy in the region (that could kill him with a sneeze even before he could react, the guy who no one in the whole place would be able to go against) bows before his h*e of a teacher just because p*ss and some randomic thing about her potentialMC also claims to have a bunch of cultivation methods for alchemists in the beginning of the novel, just some chapters later says he have read more than 10The story is dumb and the author is everywhere with it and isn't self aware.Read if you want to laugh at how ridiculous it is, other than that, don't waste your time
