Song Huaizhen, a mediocre disciple of the Canglang Immortal Sect, was banished to a remote and desolate medicine mountain, where he accidentally saved a dying withered seedling. The withered seedling transformed into an ancient tree of life, possessing powerful healing powers. The demonic army is pressing hard on the border, leaving the living creatures in devastation. The youth carries the ancient tree to dissolve hostility with gentle power, making the demon lord put down the butcher's knife. Without tragic killing, with life and kindness, he guards a world where all things are peaceful and happy.
