In ancient times, the human race relied on its unparalleled understanding, learning ability and reproduction speed. It was the leader of all races in the wild, with a splendid civilization and strong men. However, due to the jealousy and fear of all races, they were jointly attacked and suppressed. The fate of the human race was cut off, their inheritance was lost, and they were kept in "pastoral areas" as rations and slaves. Once any human race shows signs of cultivation talent or awakening, it will be "harvested" and eaten to avoid future troubles. The entire human race is trapped in a cycle of despair.
