At this time, he also activated the ghost system, and at the beginning, he gave the ultimate talent that can make evil ghosts return to the world. However, if you want to help the female ghosts re-become a human being, you have to go through a series of complicated and tedious processes, which makes Zhang Yuan complain of back pain. The most outrageous thing is that the female ghosts are all stunning beauties. Who the hell can withstand this?
