In ancient times, Ba Snake Bi'an (the male protagonist), the god of war in heaven, sacrificed his body to destroy the Yuanding cauldron to seal the demon king Zhutian. The giant snake's body was blown up, and its remaining soul had nowhere to live.
His master Chang Yujun (the heroine) is the incarnation of the way of heaven, and his mission is to maintain the cycle of good and evil cause and effect in the three realms and five elements. Knowing that the Bodhi Fruit can be used as a guide, he helps Ba Snake reshape his snake body. He and other immortals cast spells to save Ba Snake and send him to Linyuan (Ba Snake's fiefdom) to practice again. He agreed to go to Linyuan in person after a thousand years to pick him up and return to heaven. He will be rewarded based on his merits and ranked among the immortals.
Thousands of years later, Chang Yujun, who lives in the 21st century, accidentally traveled to Chang Yujun, the incarnation of the way of heaven who had a thousand-year appointment with Bi'an thousands of years ago, and started a magical and funny journey of sadomasochism...
