The ancient divine snake, Xiu Snake, was designed by an evil person and accidentally harmed all the villagers in Zhuluo Village with colorful fire. Huang Di was furious and sent Hou Yi to kill him. After 1900, Xiu She was in danger again and was rescued by Jiu Qian, a snake demon boy who had a destiny in his previous life. Xiu Snake repays the favor and presents the colorful crystal snake heart to Jiu Qian. As a result, Jiu Qian was accepted as a disciple by the ancient god Crane Xuanxiang, a friend of the divine snake. But there are also Fu Chai and Ya Yu who are also Xuan Xiang's apprentices. In their previous lives, these two people were lotuses and fairy fish in the Xuanxiang Pure Pond. In the emotional entanglement between Jiu Qian, Fu Chai and Ya Yu, the war between Wu and Yue intensified. In order to avenge his father's death and take away the hatred of his former lover, Fu Chai assassinated his master, the ancient god Crane Xuanxiang, and stole the power of the crane to deal with Jiu Qian. At this time, although Jiu Qian was superb in martial arts and unrivaled by mortals, he was still unable to control the seven-colored crystal snake heart in his body to rival Fu Chai at that time. Unfortunately, he was defeated and became a prisoner. Just when Jiu Qian's life was hanging by a thread, Xi Shi, who was the lover of the ancient divine snake in her previous life, was enlightened. Thinking of the snake heart in Jiu Qian's body, she began her life of mediating for Jiu Qian. At the same time, under the pursuit of Yayu and his good friend Feng, who are equally loyal, Jiu Qian endures the humiliation and bear the burden, and is finally tempted to endure. The colorful crystal snake heart spontaneously violently violently merges with Jiu Qian's heart, and Jiu Qian gains the power of the snake god. Jiu Qian's Fu Cha fought a duel between snakes and cranes, and finally defeated Fu Cha, annexed the Kingdom of Wu, and gradually dominated the Central Plains. However, in the process of achieving hegemony, Jiu Qian also lost his beloved master, best friend, and beloved queen again and again. Every winter, when the plum blossoms stand proudly, Jiu Qian can't help but shed tears and sigh, "The colorful crystal heart, the hardest thing in the world, can make me become more courageous the more frustrated I am, but it is difficult for the enemy to defeat the country and the enemy's love!"
