After the death of King Yan, his younger brother Shi Qi, Cihou Yan, took control of the government. The Marquis of Yan is evil in nature and has many desires. He wanted to unify the country, so he had four cages. For those who do not want to join his sect, they choose to kill them all to avoid future troubles.
At that time, Liu Huaiyu, the military commander of the imperial capital, was an upright person and did not want to help the emperor to abuse him. Later, he was persecuted by the Marquis of Yan. He was first dismissed from his official position and then intercepted and killed on his way back to his hometown. In order to save his only son, Changfeng, Liu Huaiyu had to abandon the rest of his family.
God favored him, and Liu Changfeng survived and settled in Xizhuang to make a living by hunting. One snowy day, Changfeng went out to hunt in the mountains and met Wuteng Jing. Due to his kindness, Changfeng protected him with his life and helped Wuteng Jing transform into a demon.
After Yanhou Yingquan massacred Xizhuang, Liu Changfeng embarked on a life of escape together with the Wuteng Jing.
By chance, Changfeng met Qiu Jizi, the medicine king of the generation, and with Qiu Jizi's help, he entered the fairyland, improved his cultivation step by step, and finally avenged his family.
