My Lord, Times Have Changed.

In the ancient times, heaven and earth were not divided, and the earth and Cangchu domain were originally one. Mountains, rivers, grass and trees absorb the essence of the sun and moon, and all living things can cultivate. At that time, the human race and the Chu beast were born from the same source - Cang Neng circulated between heaven and earth, and the living beings practiced to absorb energy and expel impurities from the body. Under the long-term influence of Can Neng, these impurities gradually condensed and took shape, and the first Chu beast was born: Chu Zu. Chu Zu is neither human nor beast, but is transformed from the dark side of Cang Neng and the turbid energy of living beings. It is like a reflection reflected in sewage - people have seven emotions, and Chu Zu split into seven royal families, corresponding to arrogance, greed, lust, jealousy, gluttony, anger, and laziness; people have zodiac signs, and Chu Zu gave birth to twelve royal families, corresponding to rats, cows, tigers, rabbits, dragons, snakes, horses, sheep, monkeys, chickens, dogs, and pigs; and Chu Zu himself became an imperial clan, superior to all beasts. Chu beasts feed on human flesh and blood, not because of cruelty, but because of instinct - in the Chu beast's understanding, they are the executors sent by Cang Ancestor to clean up the filth, and they are the scavengers of the world.
