Su Chen and Lin Yue accidentally stepped into the mobile secret realm of Wanxiang Immortal Mansion. This place is rich in aura and filled with treasures, but it also hides the murderous intentions of ancient beasts and demons. Su Chen, who has the root of chaos, encounters the boundary-breaking talisman guarded by the Xuanwu spirit turtle, awakens the chaos transformation, swallows the origin and other heaven-defying abilities, and even obtains the "Wanxiang boundary-breaking skill" and the demon lord's token left by the master Wanxiang.
In the secret realm, the two of them were surrounded by demonic monks led by Elder Xue Sha. Su Chen used his cultivation in the middle stage of foundation building to overwhelm the powerful enemies in the late stage of foundation building, and used the chaos sword and the power of space to slay demons. Lin Yue used the twin spiritual roots of wood and fire to fight together, and cooperated tacitly to break the situation and counterattack.
Returning with the treasure from the secret realm, the world of immortality is facing the crisis of invasion by the demonic army. The major sects formed an anti-demon alliance. Su Chen and Lin Yue relied on their secret realm income and strong strength to become the vanguard core of the alliance. They trained troops to make medicine, set up large formations, and grew up rapidly in the battle of life and death. As young men, they took on the important task of protecting the common people. In the duel between swords, shadows, and immortals, they wrote a passionate fairy tale.
