Story background
In a mountain village, a white snake that had been practicing for many years was brutally killed during the molting period. The perpetrator was Shen Xuan, the youngest son of the snake-catching family, a fifteen-year-old boy who was held in the palm of the family's hands. The snake demon Shen Wang returned and bloodbathed the village, killing twelve people.
In order to appease the snake demon's anger, the villagers pushed the murderer out - no, it was not the murderer who was pushed out. The person who was pushed out was the murderer's taciturn and unpopular brother, Li Yu.
Twenty-five-year-old Li Yu took the blame for his younger brother and was sent to the snake's den to become Shen Huan's "atonement".
Snakes are cold-blooded. But cold-blooded creatures also know what warmth is
