Liang Dong spoke a candid truth; greed is man's original sin. As long as one exists in this world, there is no avoiding greed.
But mere greed alone isn't a good reason to give up a stable job to become a mercenary and earn blood money.
Money is something everyone loves, robbing a bank is quick money, but hardly anyone robs banks; why? It's because the risk is too high, and getting caught means death. Even a desperado wouldn't resort to this unless there's no other way, because the risk is too high and far outweighs the benefits.
Being a mercenary isn't much different; it's still a business where you trade your life for cash. The previous invitation from Satan to Liang Dong was declined. Now he's got a stable high income, and he's opting to risk his life for money, which is hard to understand.
Gao Yang is not a boss who's fond of setting up obstacles for people, but Liang Dong's inconsistent attitude makes him uneasy if he doesn't get a clear answer.
