Gu Yang had originally planned to spend his whole life lying around, but suddenly activated a hot-blooded Naruto fighting system.
System: You can get stronger just by fighting!
Gu Yang: There's no way I'm fighting. Not in this lifetime.
System: Host, refusing to accept a mission will be punished with castration.
Yan Luo: O_o Ancestor, hurry up and fight me!
Ancestor: Get lost.
Gu Yang: If you don't fight me, I'll die.
Ancestor: If I fight you, I'll really die. Get lost, as far away as you can!
Gu Yang: Sword God, let's fight!
Sword God: Again?! Ugh!
Gu Yang: Your Majesty the Empress, have mercy! Isn't it enough that I surrender?
Empress: No. Again, I'm getting impatient.
PS: One female lead.
