To cultivate the Tao means to ask the mind. Yu Xian, an orphan from Dayushu Village, lives with the spiritual tree in the village. When the spiritual tree was robbed, the tree lady used her last soul to open up spiritual roots for him, leaving behind a thread of immortality and endless concern. Carrying this heavy protection, Yu Xian stepped into the world of immortality. In the Baiyun Sect, thanks to the guidance and protection of his master Xiao Wusheng, who was like a father and a friend, he gradually emerged on the path of alchemy. However, in the secret realm of Shengxian, the cruel laws tested his Taoist heart. This is a path of enlightenment in which one takes the body of a wood spirit, sticks to one's heart in the mortal world, and protects one's loved ones with strength. Yu Xian will take this warmth from life and embark on his own path to immortality.
