Qin Yue is a handyman disciple of the Qingyun Sect. He was born with five spiritual roots. After three years of cultivation, he is still trapped in the third level of Qi Refining and is regarded as a "waste" by the sect's genius. Su Qingyuan is the only female apprentice in the Alchemy Hall. Although she has an innate medicine heart, she has an incompetent constitution. She cannot condense spiritual energy to activate the Alchemy Fire and can only do chores of sorting herbs.
During a secret trial, the two accidentally broke into the tomb of an ancient monk. Qin Yue obtained the "Spiritual Root Purification Bead", which was able to swallow spiritual materials and purify the bones. The five spiritual roots gradually condensed into the rare "Five Elements Spiritual Body"; Su Qingyuan used the elixir of the tomb to break through the shackles of the body, awakening the "alchemy aura", which can use the elixir to activate the aura of heaven and earth.
Just as the strength of the two of them was advancing by leaps and bounds, the protector of the Netherworld Valley's foundation-building period came with evil crowds, hoping to seize the spiritual root beads to refine evil weapons and subvert the entire world of immortality. Qin Yue, who was on the fifth level of Qi refining, used the Five Elements Spiritual Body to overturn the pressure of the foundation, while Su Qingyuan refined the "Breaking Realm Pill" and "Spirit Protecting Pill" to assist in combat, and could even use the heart of medicine to control spiritual plants to lay out killing arrays.
From fighting to the death in the secret realm to guarding the sect, the two went from being strangers to each other to having a tacit understanding. In their repeated confrontations with the foundation-building evil cultivators, they not only unlocked the ultimate secrets of spiritual roots and alchemy, but also revealed the shocking secrets behind the spiritual root beads related to the immortal world, and wrote a counterattack legend with their Qi-refining bodies.
