Bai Jiu (Li Lun) rushed to the secret room and realized that what Zhao Yuanzhou said was true. He wanted to kill Wen Zongyu, but he didn't expect that Wen Zongyu had already poisoned Bai Jiu (Li Lun).Wen Zongyu wanted to use the antidote to Bai Jiu (Li Lun), but Bai Jiu (Li Lun) made Wen Zongyu give up this idea and he would never be controlled by others.Because the Yun Light Sword is Zhuo Yichen's natal weapon, he and Zhuo Yichen share the same feelings.Now the Yun Guang Sword broke, causing Zhuo Yichen to fall into a coma.Pei Sijing and Ying Lei also learned from Lu Wu that the only way to strip away Li Lun's spiritual consciousness and rescue Bai Jiu was by relying on the Yun Light Sword.
In order for Zhuo Yichen to fully recover, he must recast the Yunguang Sword, otherwise Zhuo Yichen will be weak and die.At this time, the five-color stone was induced by the Yunguang Sword and appeared in the Demon Hunting Department.The five-color stone is a treasure passed down from generation to generation by the Bingyi tribe and can repair the Yunguang Sword.At this moment, Bai Jiu (Li Lun) appeared in the Demon Hunting Department and snatched the five-color stone, but the five-color stone was shattered.A drop of demon blood hidden in the five-color stone entered Zhuo Yichen's body.
Zhao Yuanzhou told everyone that in ancient times, Zhuo Yichen's ancestor Bingyi was also a demon. Because of his meritorious service in killing the evil demon Yinglong, Empress Nuwa granted him a wish.Bingyi's wish was to become a human, so Empress Nuwa melted the inner elixir for him to help him become a human. However, she did not want Bingyi's God of War power to dissipate, so she used a five-color stone to preserve a drop of Bingyi's demon blood.
