This is a world of cultivation with beast control as its core. Thousands of years ago, countless mysterious space cracks suddenly appeared between heaven and earth, and eggs and cubs of ancient beasts descended into the world from the cracks. Human beings discovered that they could use their spiritual power to establish soul contracts with these strange beasts, forming a master-slave relationship between the beast master and the beast master. After thousands of years of development, beast-controlling civilization has become the absolute mainstream in this world.
