In ancient times, it was not called the "Era of Holy Light" but the "Era of Gods and Demons". At that time, the demon Chiyou did not die in Zhuolu, but led the Jiuli Eighty-one Division to compete with Xuanyuan Huangdi for Kyushu. In the end, the Yellow Emperor gathered the power of all the spirits in the world and did not kill Chi You. Instead, he dispersed his true spirit and suppressed him together with the old Jiuli tribe at the bottom of Guixu - the endless abyss at the end of the East China Sea and under the return flow of thousands of waters.
After the Yellow Emperor ascended, he left behind the "Seal of Heaven", and Kyushu entered the "Era of the Human Emperor", a time of eternal peace. People and emperors in the past generations patrolled the sky, there were many immortal gates, and the righteous path prospered. The Guixu seal has been guarded by the Sixiang family from generation to generation and has become the highest taboo that no one dares to mention.
Until this day, Guixu Haiyan suddenly hung upside down, and the whispers of the abyss began to sound at the sealing nodes all over Kyushu at the same time. In the bloodlines of those Jiuli descendants who were exterminated, the sleeping demonic blood began to awaken. The historian secretly recorded this incident and wrote only eight words: The abyss awakens, and the era will change.
