MTL - God Level Star System - Chapter 3 Activation system and English test

Shi Qing’s task was to be a protector.

An 18-year-old poor college student tried to apply for a job as a tutor but his life almost ended as demons' meal. In his last breath, a mysterious woman gave him a strange power. When he opened his eyes he had turned into a demon with a system that would turn him into… A pervert.

Now he must lived with his dual identity as a model student named Ethan and an incubus named Damian.

Shi Jin once read a book. It was supposed to be about satisfying the desire for vengeance.
