After Yu Xian's mother dies, she transforms into the great elm tree in their village to protect him. However, on the day she is supposed to take human form, she is brutally murdered by an evil cultivator. Before her spirit dissipates, his mother bestows upon him a spiritual root and a protective jade pendant, guiding him onto the path of immortal cultivation. By a twist of fate, Yu Xian obtains an Ascension Token and joins the Baiyun Sect. Because he possesses an inferior-grade Wood Spiritual Root, he is banished to the mining district. Using the jade pendant, he discovers an enormous abundance of ores, allowing his cultivation to advance by leaps and bounds. When the mine supervisors repeatedly scheme against him and attempt to kill him, he fights back to protect himself. He unexpectedly reveals a talent for alchemy and becomes the disciple of Xiao Wusheng, a renowned master of the alchemical arts. During the trials on Ascension Island, Yu Xian endures brutal battles, undergoes a transformation of his spiritual root, and grows stronger with every step. He vows to kill the evil cultivator and avenge his mother!
