Story of: I am in Ice Emperor! World destroyer
His name is Kurosaki Ryuichi. When he traveled to the world of Net King, he did not have the invincible system like other time travellers, but only a steel-like body.
But he relied on this body to create his own great reputation.
The world calls him this: Destroyer of Worlds!
Duke: He is the real King of Destruction!
Polk: He ruined my tennis!
When Kurosaki picked up the racket, the world trembled.
