Liushugou has suffered a prolonged drought, with no rain in sight. The fields are cracked and the villagers struggle to survive. Zhu Chan, who is in charge of arranging rainfall, joins forces with the immortal merchant Boss Jin to introduce a paid membership system for rain, exploiting the desperate villagers for profit while turning a blind eye to the suffering of ordinary people. Mu Huaixi appears to be an ordinary woman, but she possesses ancient dragon power and a compassionate heart. Unable to bear watching her fellow villagers beg desperately for rain only to face endless obstacles and humiliation, she steps forward to challenge the unjust rules. Using her own power, she brings life-giving rain back to the earth, protects the people, and restores justice to the world.
