In the ancient times, the heaven and earth were unstable, and hundreds of millions of creatures were in danger of being destroyed. In order to complete the number of heavens, Hongjun, the ancestor of Taoism, combined his body with Taoism and became Hongjun of Heavenly Dao. His disciple Nuwa was grateful for the mercy of heaven and earth, and used her own blood to create a human race at the foot of Mount Buzhou. After the calamity, the world is divided into three realms: immortal, mortal, and netherworld. For thousands of years, the two realms of immortality and the underworld have used their capital to get a taste of the way of heaven and run rampant in the world. However, there are also many talented and awe-inspiring people in the world who uphold the Taoism of the ancestors, obtain the fragments of the skills, use their mortal bodies, and use the power of magic weapons to eliminate demons and kill ghosts and gods. They are invincible in the world and are called cultivators by the world. Zhang Fengyu, an ordinary young man in a town, accidentally encountered a fight among cultivators and escaped death but got a secret treasure. A mysterious fortune teller appears, three rare treasures appear, and for a while, sects quarrel and demons emerge... Is all this a coincidence, a entanglement buried in ancient times, or a huge conspiracy? The divine sword whispers, and the sword's edge can destroy everything it points to, but can it break this fateful cycle?
