I Am the Demon King in the Demon World

Since ancient times, it has been said that the three realms are at odds. Since the spiritual power in this world has gradually become scarce, demons rarely go to the human world. So I don't know when there was a rule that the two realms of demons and demons were not allowed to set foot on the human world unless there was anything wrong. After that, the opposition between the three realms became two realms, and the situation between the two realms of demons and demons became as dangerous as a pinhead. The current demon king, Wu Peng, wanted to calm down the dispute between the two worlds. He worked hard for thousands of years. He was killed while outing and wandered around the world. He accidentally possessed a human boy. In order to find out the truth, the two joined hands to level up and fight monsters to find the truth and settle the thousand-year grudges between the demon and demon worlds.
