I don't know how many epochs later, in the immortal world, under the leadership of the victorious Buddha Sun Wukong, the evil demons were slain, and the good demons were collected in the demon clan autonomous region of the immortal world, cutting off the path of becoming demons. When there were no more monsters on the human world, the Jade Emperor cut the connection between the immortal world and the human world with a sword. At this time, 14 little demons hid deep underground for unknown reasons, and 5,000 years later, they transformed into human beings and quietly caused harm to the world.
