Synopsis：The Heavenly Emperor made a wish during his birthday banquet to travel through the mortal world. Unable to dissuade him, the immortals stripped him of all his divine powers to maintain order in the human realm, allowing him to descend successfully with the Three Realms Stone. Upon arriving on earth, the Heavenly Emperor was arrested by local authorities for damaging a statue of a deity. While being punished in a temple, he developed feelings for a girl who came to burn incense—actually a fox spirit in disguise. The fox spirit tricked the Heavenly Emperor into a brothel, where the Demon Emperor, disguised as the madam, attempted to steal the Three Realms Stone and kill him. Just then, Xu Mengjiao arrived with his team to investigate the case, and the Green and White Snakes, having received word, also rushed to rescue their master. In the chaos, the Demon Emperor, lacking sufficient power, was forced to flee. Later, Xu Shilin fell under the Demon Emperor's possession, and the White Snake could not bear to kill "Xu Mengjiao." Enraged, the Heavenly Emperor parted ways with the Green and White Snakes. Seeking help from mortals and lesser immortals, he discovered that his authority in the human world had completely vanished, leaving him to fight the Demon Emperor alone. Moved by his determination, the people resumed their offerings to the Heavenly Emperor. In the moment of crisis, he regained his divine form through their devotion, ultimately vanquishing the Demon Emperor and restoring peace and stability to the Three Realms.
