He Just Became a Demon King and Was Summoned by the Common School Beauty.

After traveling to another world, he finally became the Demon King, but he didn't expect that it was actually a trap. He had been trapped for 18,000 years as soon as he became the Demon King. Fortunately, I finally broke through the space and escaped, but I didn't expect that all my magic power was lost, and the system was awakened at this time! However, the cheating thing is that the system actually turned him into a bonded spirit. That's okay, but why did he turn into a little kid wearing diapers? The little devil with a milky voice looked at his body and was very angry: "I can't accept this!" The bloody thing is that as a bonded spirit, he can't go out if he can't reach a contract with a human being, so he has no choice but to sign a contract with a common school beauty and become her bonded spirit, which makes the whole room burst into laughter! "Holy crap! Did the goddess summon a milk baby?" "The school beauty becomes a wet nurse?" Chu's mother: "Am I becoming a grandma? Wait, is this spirit-loving man a woman?" Just when they were about to open their diapers to find out what was going on, the little devil disappeared on the spot. "Bold, how dare you think of blaspheming this king!"
