After being murdered by his daughter's fiancé, Guo Huaian, Ye Qingcang was reincarnated as a peach tree in the courtyard and bound to an evolution system. By collecting human emotional value, he continuously evolved, from mastering vines to hardening his bark, secretly protecting his daughter, Ye Yuanyuan. Coveting the family fortune, Guo Huaian repeatedly attempted to burn the peach tree, but was thwarted by Ye Qingcang every time. Guided by the peach tree, Ye Yuanyuan gradually saw through the truth, ultimately fleeing her wedding and reuniting with her father. Ye Qingcang accumulated enough emotional value to complete his final evolution, transforming into human form, turning the mother and son of the Guo family into flies, and reuniting with his daughter.
