I am a Gao Fushuai Villain - Chapter 360:

In a world where monsters dominate, and humans are but one out of ten thousand of the population, Gao Yang, having transmigrated to this world at the tender age of six and led the life of a normal boy until his eighteenth birthday, must seek the truth and survive against all odds—with the help of a mysterious system, a bottom-of-the-list Talent, and the companions he meets along the ways.

What is hidden under the facade of an ordinary city and its ordinary occupants? What are these different manners of monsters, and where is the line drawn between monsters and humans? Could relationship and love be true when all are merely playing their own parts?

Ride along on his journey and find out!

He almost got killed when he realized the truth, and he would, if not for the system and Talent he acquired at the last moment, Lucky—the longer he lives, the stronger he will become!

Now commenced the battle royale of a lamb among wolves…
