This is a story about the human heart and ancient magic weapons. After Pangu died, Nuwa divided the Pangu ax that could open up the world into five parts using the Five Elements technique. They are the Heaven-shaking Divine Bow held by Hou Yi, the Qinrui Ge held by Chi You, the Sea-Dinging Needle held by Xuan Ming, the Shennong Whip held by Emperor Yan, and the Xuanyuan Sword held by Huang Di. In the beginning, the five ancient divine weapons did play a role in balancing the yin and yang energy of heaven and earth. However, with the passage of time, especially the struggle for the dominance of the newly born creatures in the Three Realms, the God Realm gradually divided into two factions, the Yellow Emperor Clan led by Xuanyuan and the Yandi Clan led by Shennong. The two races are in sharp opposition. In the end, a war inevitably broke out, and Hou Yi and Chi You were the first to become the victims of these two clans, and the magic weapons they held were also sealed successively. In this way, for thousands of years, time flies by, when people only use Hou Yi to shoot the sun and the Battle of Zhuolu as topics of conversation after dinner. A shocking conspiracy that has been hatched for a long time is being quietly planned. In the end, this led to a major disaster for the Tianshu Sect, the Yuheng Sect and even the human world. The Innate Bagua Map was destroyed, the Hetu Luoshu was lost, and the twenty-third generation head of the Tianshu Sect died in battle, all because of that ancient magic weapon and the long-lost legend about the human heart.
