@ShionSinX Are we talking about the same person? If i got it right Mr Oh Se-Chan believes he's quite skilled and is testing him. All they have been doing are deals, where he never really tried to kill him. He has to be cautious, since last live Messiah killed him and took all infos on the dungones he had. Don't think he ever treated him as bait. Might have missed or forgot something.
As for his friend the immortal Lee Jin-ah, he obviously doesn't trust anyone especially someone who arrives and behaves so confidently like our protagonist. But the first thing he did was pretty much insult him. True he has the power now, but he knows his powers and from the mentioned bits he does acknowledge his powers. He can easily show his superiority he has now, without right off trying to make him hate our protagonist by insulting and threatening him.
He would be a great accomplice to take down Messiah.
The following chapter doesn't seem that bad, but for some reason I didn't like the protagonist's behaviour in this one.
Except the few friends who were killed by Messiah his past live, the protagonist treats everyone as enemy, but doesn't even try to contact any of his friends, either.
I hope I could more or less convey, why I didn't really like the protagonist's behaviour this chapter.
