The human world, the divine world and the demon world do not interfere with each other and have rules for each other. As the youngest clam spirit in the tribe, Su Ye was supposed to live a carefree life in the sea. But Suye's mother broke the rules and had a love affair with Qiyun, the fruit of which was Suye. However, the good times did not last long and she quickly discovered Qiyun's deeds. She chose to leave in despair. In order to tie up the clam clan, Qiyun allowed Suye to travel between the ocean and the heaven at will under the pretense of protecting the sacred objects of the heaven. She also became one of the "guards" of the sacred objects and got to know Xuan Yi since she was a child.
Qi Yun understands the nature of the demon world and uses this to provoke, and a traitor appears within the tribe after being bribed, causing the whole tribe to be involved in a major disaster.
