The two gods in the heaven, the water god Yunlan and the Tianjingsha Shenxi, were deprived of their godhood and memory because of violating the laws of heaven, and were demoted to the "Dayin Dynasty" in a different world. The divine power is sealed and the spiritual power is weak. Only on the line between life and death or deeply moved can one glimpse the afterimage of the god.
She is Shangguan Cheng Xi, the pearl of the Zhenguo General's Palace, who is born with a glow, but is trapped in the whirlpool of the court; he is the reclusive prince Yun Lan of the Jingnan Palace, who is frail and sick, and hides the secrets of time and space. A royal marriage tightly binds two souls who should be strangers.
The mortal world has experienced tribulations, and every step is startling: identity confusion, power struggles among powerful ministers, sect battles, and even the mysterious power "Dark Emperor" who intends to devour the world is hidden. In the struggle for survival, the dormant divine power in the body quietly erupted like a volcano. From mutual repulsion to mutual understanding, from responsibility to heartbreak, every time we fight side by side, we are asking: Is this love a disaster or fate? Is it obsession or fate?
When the shadow of the "Dark Emperor" envelopes the three realms, mortal creatures are on the verge of disaster, and the sleeping gods finally awaken! Shangguan Cheng Xi activates the light of day to purify the world of filth; Yun Lan controls time and space to reconstruct the collapsed order. The waves rise, the clouds open, and the divine light appears again.
The calamity is completed, but we are faced with a choice: return to heaven, or stay to protect him? In the end, they chose to take root in the mortal world, maintain the balance of the three realms with their divine power, and become the eternal legend of Dayin - riding on the waves and clouds, showing the true light of day, and guarding the world they loved so much.
