More than 2,000 years ago, Gu Huai, the Azure Dragon God Lord who had no strength left in the God Realm due to repairing the rupture of the world, died trying to seal the demons. All that was left were Cangshan and the mixed-race twins he picked up.
That battle "The green dragon fell, the demon clan was sealed forever, the two foxes cried blood, and the heaven and earth were in sorrow."
After that, Siming established a special investigation bureau to maintain the relationship between the six realms, and the twins' personalities changed drastically. The elder sister became a "cold-faced evil god" and the younger brother became a "smiling fox". Together with the other three talented people, they completed the last wish of the twin masters in modern times - to seal the demon clan, and Siming ensured their safety while searching for the divine weapon. During this period, Siming's love for Wu and Wu, the companionship of his partners, and the warmth of the Special Bureau healed the wounds suffered by the twins in that battle.
Purpose: Seal the demon clan
