Mucheng and Changning were originally a couple, but thousands of years ago, alien beasts caused chaos and harmed the three realms. Changning was a sealed alien beast and lost all his divine power. Before the calamity, he issued an order for Mucheng to receive three thousand lashes from heaven. At this point, the two broke up.
Thousands of years later, the seal began to loosen. In order to seal the strange beasts again, Muzhen was asked by the heaven to travel to the lower world to travel to the gods.
After going around for thousands of years, the two met again.
Intention: The way of heaven will always have feelings, and it will help others as well as oneself.
