Shen Moyan, the number one swordsman who retired from the world of immortal cultivators, transformed into a delivery boy and lived an ordinary life. However, when delivering orders on a rainy night, he was accidentally involved in a shocking conspiracy - Su Wanqing, an ordinary employee, was actually chosen by the evil cultivator as a sacrifice on the Blood Moon Altar. With a special spiritual vein, she became the evil spirit's target.
The swordsman who used to kill decisively has now transformed into a madman who protects his wife. In order to protect Su Wanqing, he did not hesitate to expose his identity, perform forbidden arts to change his veins, abandon his centuries-old cultivation, and use himself as bait to fight against the Blood Moon Altar and the evil cultivators.
When the identity of the ordinary delivery boy was revealed, the hidden sword fairy returned to the battlefield, wielding his sword energy to kill evil spirits and protect her every year. The fate of the world of fireworks and cultivating immortals is intertwined. He said: "Cultivation is something that can be practiced again. If people are gone, they are really gone."
