"I reiterate, I am not only a villain with a system, but also an extremely stingy scumbag. Don't come close to me again!" Traveling through the parallel world, Gu Yuan just wanted to rely on the [Devil King Development System] to do some petty theft, save money to buy potato chips, drink Coke, and sleep in. But the devil's wish was not fulfilled. The newly reborn No. 1 School beauty climbed through the window and kissed her forcefully in the middle of the night. He must be the savior in the dark night.

From that day on, everything went wrong. He just wants to lie down and live his life, they say he is recharging his energy and waiting to see what happens; He wanted to cause chaos, and they said it was a secret plan; He casually taught a few little Karamies a lesson, but they decided that he was playing a big game to save the world.

The girls' faces were full of enthusiasm: "Understand, your identity cannot be revealed yet!" System: [Congratulations to the host for successfully deceiving the world. The Demon King's prestige has increased ten thousand times!
