Mountain village woman Ye Zhi encounters an injured psychic red snake, feeling compassion in times of danger and rescuing it with all her might. Understanding human intent, the spirit snake steps forward to protect the people with its body when the village faces flash floods and crises, in repayment of the grace of saving its life. Facing the covetousness and persecution of greedy people, Ye Zhi and the spirit snake share a meeting of hearts and minds, uphold morality, and jointly resist dangers with unyielding will. In the end, evil thoughts bring self-inflicted consequences, good deeds exchange for a consummation of merit, the red snake sheds its mortal coil to transform into the Dao, wind and rain disperse, and morning light pierces the fog. With "all things have spirit, good and evil are rewarded" as its core, the book demonstrates cross-species trust guardianship and sincere great love deep within human nature.
