Previous story: Yun Zhongjun and the flower fairy Zhuo from the third heaven were in love, but unexpectedly, Tianjun Chaofeng blocked them. Because he was afraid of the power, Yunzhongjun personally gave Huazhuo to Tianjun Chaofeng.
On the day Tianjun married Hua Zhuo, Yun Zhongjun made an excuse to go away to fight, and said goodbye to Hua Zhuo in the Cloud Corridor. Before leaving, he gave her his Yin Yang Sword. Unexpectedly, after turning around, Hua Zhuo jumped off the Cloud Corridor holding the Yin Yang Sword.
The Yin Yang Sword broke into two halves after falling from the fairy world. Half of the Yang Sword fell into the Dabie Mountains under the control of Immortal Siming, while the sword spirit became entangled with the Huazhuo Immortal Spirit and fell into the dark and lightless abyss. The other half of the Yin Sword body and sword spirit fell into the Yunze territory controlled by Yun Zhongjun.
In order to keep the Yinjian sword spirit spiritual, Yun Zhongjun recruited immortal cultivators from all over the world and fed the sword spirit with their blood. Immortal cultivators who came one after another boldly and greedily hoped to ascend quickly through this method, but they were all killed by the sword spirit.
Three hundred years later, a young Taoist named Qin Zhiheng finally withstood the Yin Sword Spirit's backlash, fused the Sword Spirit with his own human spirit, and successfully ascended. At the same time, he was also entrusted by Yun Zhongjun to start looking for the other half of the sword spirit in the three realms of immortality, human and underworld.
