In a martial world where the strong prey on the weak, Su Yi, a boy from Qingyan Village, is an ordinary farmer's son. But fate takes a hand, sending him down a turbulent road to rise against the odds.
When a pack of wolves suddenly attacks, Su Yi is rescued by Uncle Liu, an outer sect steward of the Moyuan Sect, who takes him on as a nominal disciple. At the sect, Su Yi befriends Chen Xuan, who seems honest and simple-minded. The two become close, but beneath the sect's peaceful surface, undercurrents are stirring.
The Moyuan Sect and the Ziyan Valley have long been at odds, and a fierce battle descends without warning like a storm. In the brutal fighting, Su Yi is stunned to discover that his dear friend Chen Xuan is a spy for the Ziyan Valley. This betrayal costs Uncle Liu his life and leaves the Moyuan Sect badly damaged.

Along the way, Su Yi must face countless challenges in both the jianghu and the cultivation world, as well as uncover the astonishing secrets hidden behind it all. Is this the cruel hand of fate, or a call to fulfill his destiny? Can Su Yi turn the tide in this ever-changing world and earn the title of Profound Immortal?
