Substitute - Chapter 15

When a glorious old civilization was toppled overnight, a strange purple moon rose and thus began the Purple Moon Era.

Hell Ghost Wang Wannian is born again, smiling and proud!
What?
Are you a soldier, will the tank drift?
You are a master, can you give birth to dragons and tigers?
You are a superman, can you call the wind thunder?
Excuse me, I am not targeting anyone, everyone in my eyes, it is rubbish!
