Lin Chen and Su Lingxi were originally inconspicuous monks in the mortal world. They went to Kunlun Fairy Mountain together to seek enlightenment, but they were accidentally involved in a shocking secret that spanned the three realms.
On the fairy mountain, the righteous sect is hidden and corrupt, and the ancient inheritance is coveted by traitors. The two survived the trial after nearly dying, and unexpectedly encountered the remnant soul of an ancient immortal in a desperate situation, and obtained the true secret of chaos that had been lost for thousands of years. This technique can integrate the five elements and break all laws, but it also attracts the pursuit of the good and the evil - the good denounces it as a demon method, while the evil cultivators want to seize its secret book.
They escaped into the ancient secret realm, avoiding pursuit and killing, while refining their true skills and experiencing growth. From dangerous monster lairs to strange ancient ruins, the two work together to break through formations and kill enemies, conquer spiritual pets, find treasures, and their strength soars rapidly. As their practice deepened, they discovered that the secret of sealing the Demon Lord was hidden behind the true technique, and the truth that the seal was loosened and the Demon Lord was about to resurrect also emerged.
When the Demon King's minions swept across the world of immortality, Lin Chen wielded the Chaos Sword and the power of Su Lingxi's spiritual veins to activate the ancient formation with true secrets, and joined hands with the righteous people to fight against the demonic tide. A battle related to the survival of the Three Realms begins, and the road to enlightenment finally becomes a battle to protect the Dao. With their blood and true skills, they compose a fairy tale!
