So this one has lots of weird elements, including an MC who was born to the Tang Sect, a cult so awful that the MC felt he had no choice, from the first chapter, but to commit suicide, because he (justifiably) didn't accept to only be a low-rank individual, as determined by his birth and rank in the cult..
So what does the MC do, after being reborn in another world? Why, seek to recreate the same cult, of course! (Mind control is a terrible thing)
Then we get all the teenage bullies the MC teams up with. None of them are more than thugs, and all they do is go around looking for fights, bullying those weaker than them.
How about the side story of how the one very young teenager's regular visits to a ghetto brothel ended up in his getting a really slight beating from some older dude who wasn't having any of this little wannabe thug's attitude (after all, they are all relatively weak early on).
With just these little bruises as a reason, the team of teenage sociopaths decides to gang up on the old guy, and basically cripple him in a horrifying fashion, afterwards regretting not having just murdered him outright, since obviously now, this guy has some serious beef with them.
Frankly, these protagonists all deserve to meet a bad end, so much so that I just couldn't care about any of their travails after a while.
Then it starts to get downright disgusting when the incest subplot gets mixed in:
The MC's master accidentally fell in love with his half-sister (not cousin), only to find out just before the wedding and have to break up with her... And evidently, even in that world's society, such close blood ties make marriage and children unacceptable, which is why the MC's master cannot accept his poor deranged half-sister's advances.
Rather than encouraging them to just move on and find other people to be with, we instead have to bear witness as the half-sister keeps trying to jump her brother, and we are all supposed to cheer?
I have zero fantasies of being with overbearing, dangerously violent, incestuous, post-menopausal and clearly demented dragon-hags!
And perhaps even worse, since this affects the normally simple pleasure of powerups:
To top it all off, we have a world setting wherein it seems like it may be a grave sin to go around killing intelligent animals just for powerups, but the powerups are so tempting that who could say no?
The MC's gf supposedly cares about the animals, but not consistently (at all), and in any case she is one of the most vicious and psychotic of them all, so I can't imagine her doing anything good about anything.
In this world, special people are billions of times stronger than regular people, only it takes decades to train, so of course the protagonists only ever meet people of the appropriate power level to allow them to beat down all the other bullies they meet (100% bully world).
These stupid little cretins are so freaking lucky, since obviously it normally would only be a matter of time before someone smarter, stronger or luckier showed up and taught them the painful consequences of a Thug Lyfe (TM)!
P.S.: some stories (ex: Claymore) have great reasons for fighting and risking one's life. This one REALLY doesn't.
