So Luo Kai would have done nothing in his life and could just lie back and enjoy himself. Unfortunately, he unexpectedly awakened the most dangerous profession that no one has ever successfully activated: the Demon King! At the beginning, you must make a contract with the random demon. Either you know the devil's real name, or you have a fight with the devil! However, when the devil appeared, he said he was very familiar with it! Isn't this the popular Queen Rias and Tacheng Kitten; and Rem from Zero? Others don't know the devil's true name, but he knows it! As his strength grew, he contracted more and more demons.
