From a player's perspective, the issue is even simpler.
What do players pursue in a game?
Strength, martial arts, equipment, skills...all that matters are these things and nothing else.
What about the benefits of joining a clan?
What the heck is that? Can it increase attributes?
If not, players obviously wouldn't care.
After surrendering, all they need to do is to explain the situation clearly, and then they can get a reward of 100 gold coins! The price they has to pay is nothing more than spending a few hours in jail.
Is it possible to earn 100 gold coins in a few hours?
Throughout the game, how many people dare to say that they can?
Of course, if the players participating in the mission are clever enough, they will definitely think about the possibility of losing Yu Canghai's trust and causing a significant drop in his favorability.
