Travel into Turtle Soup and Become an NPC

Tan Xu's family went bankrupt, and in order to avoid debts, he ran to a remote place in the backcountry. I originally thought that if I burped my fart, I could go to heaven or hell. Unexpectedly, he entered a parallel world and became an NPC in Turtle Soup. As long as you become the first in the service excellence list, you can realize a wish. So, it's strange that he wants to return to the real world. What he really wants is to dominate this parallel world.
