Empire Black Knight

Fang Heng was transmigrated to a parallel world and his soul was forced into the body of a man who had just committed suicide.
Huh? What? Every human here was being forced to join a game? Those who refused would be killed?

Damn! The S-rank skill evolved! My zombie clones could auto hunt!

Hm... What an interesting game!
