Wu Chang originally acted unintentionally, wanting to catch Liu Wu's handle, to use it to coerce him and extract some information.
Unexpectedly, this move hooked a big fish.
When he went in, he was clean and tidy, seemingly an ordinary villager. But Liu Wu came out in a different attire, with seventeen or eighteen faint red grudges following him.
The owners of these grudges were all players.
The last scene they encountered in life was being dragged into the Ghost Cry Forest by Liu Wei and Liu Wu, tortured by various cruel methods, until death.
This kind of experience should have tightly bound their grudges to Liu Wei and Liu Wu, but inside the village, Wu Chang had never seen any trace of grudge on their bodies.
The reason they could escape these grudges should be related to the attire on Liu Wu's body.
