Seeing the cause of justice, the student Ning Tianlin, who was strangled, accidentally gained a combat system in the local government and returned to Yang.

What the hell, your fighting power is only fifty, then you still pretend to be me! I’m sorry to tell you 10,000 points of combat power!

What are you doing, have you been boiled down, trained in martial arts, and practiced iron gear? The fighting power is five hundred? That has something to do with me, I won’t tell you, the clothes I wear, but combat equipment! Just a single underwear, can add a thousand fighting power to me!

Hey, why do you say my combat power has increased so fast? Can I tell you that if I step on an ant and destroy a cockroach, can I increase my combat effectiveness?
