I Am the Great Mastermind

[Behind-the-Scenes Schemer, Infinite Realms, Unstable Protagonist Who Goes on Occasional Psychotic Rampages]

Before the apocalypse arrived, Jiang Sheng, a patient in a psychiatric hospital, became bound to the Main God System.

The System told him he would inherit a Rubik's Cube, which he could use to create games and send people into them to obtain survival supplies and skills for the apocalypse.

Jiang Sheng nodded. Sounded kind of fun. Then he took off like a wild horse, creating a series of games that were anything but human.

System: Why is there only one road? Where's the danger? The killing and competition?

Jiang Sheng nodded, as if enlightened, then brought out bicycles, electric bikes, tricycles, and cars.

“The battle for vehicles starts now!”

System: A mysterious ancient castle, filled with terror. One wrong move and you'll lose your life.

Jiang Sheng immediately set up a haunted house and threw a big Halloween party.

System: Deceased.

Much later, Jiang Sheng sat in his seat and laughed. “Who's the master here, you or me? Learn some manners.”

System: ...I was wrong.
