So now we get a world where only Tang San gets hurt

Indeed such a disgusting place should not exist. Even though it acts as a prison for the evil spirit masters, blood trading, drinking, etc are too disgusting. Compared to Tang San doing it so that no other person can get Killing God domain. He can do it because he might truly consider this place disgusting and even if evil spirit masters don't have a place like this to go to, at least there won't be any situation like douluo dalu 2 considering Spirit Hall would never get destroyed because of him.

The author probably doesn't want to write scenes of dating , confession, etc. So he thought of this kind of saying which lets him write less.

My everything hurts from laughing.

If your parents abused you and didn't treat you well during your childhood and after becoming stronger you kill them, it is justified, at least in that kind of world and even in this world. But following someone else's orders to kill your own clansmen and loving family is too disgusting. Fugaki was said to have taken Itachi to a battlefield at age of 4, that's how he developed his so called Hokage thinking, but in most places he was a good father even if he was not a competent clan leader, Mikoto definitely the best mother towards both her sons. Yet he only cried while killing them for the village. It doesn't matter to him what his family did for him, it matters to him whatever the village did for him which is nothing.

Raftel actually sounds like an island.

Still a good choice considering this is a training feedback system. Others in the Konoha 12 are limited in their learnt techniques. So just tag the one who would reach the Six Paths level but still has to train and has gotten exposure to most paths. Ninjutsu, Genjutsu, Taijutsu, Senjutsu, Kenjutsu.
