Mo Xuan, the prince of the divine world, was demoted to earth because of the priest Yaoying who protected the fallen ghost. When he was impoverished, hungry and cold, he met the emperor He Xuan of the human world who was visiting incognito incognito. The young emperor generously donated his money and broke half of the big cake he brought with him to Mo Xuan. As the saying goes, eating people is short of mouth and taking people is short of hands. In this way, he was abducted to the palace and became a general, and together they saved the precarious country.
