In the era of spiritual decline ten thousand years later, the world of immortality has long lost its former glory. The monks no longer pursue ascension during the day, but are obsessed with how to lie down and enjoy themselves in their limited life span. The once peerless swordsman returned after reshaping his body in an accident, only to find that the world had become unfamiliar: the spiritual energy was as thin as wine mixed with water, the magic weapon had become an antique, and even the lover who once kept saying that he would accompany her to fight the sword to the end of the world has turned into the aloof and ruthless Heavenly Dao.
