1. Era background and disaster: After China's highly developed scientific and technological civilization encountered an unknown disaster, the recovery of the earth's aura and alien invasion occurred simultaneously. Human beings have been reduced to the bottom, and can only regain their dignity by awakening to the strange beasts in "The Classic of Mountains and Seas".
2. Native beasts and the law of the jungle: The original animals and plants on the earth absorb the violent aura and mutate crazily, evolving into "native beasts" entrenched in ruins and wilderness. All high-level training resources are occupied by alien beasts. Beast masters must step into the dangerous wilderness to hunt alien beasts to "steal food" and obtain crystal nuclei and flesh and blood essence for training.
3. The law of symbiosis (life and death contract): The beast master is bound to the soul of the mountain and sea beast, and they live and die together. When the divine beast dies, the beast master will die; when the beast master dies, the divine beast will also dissipate. This requires the protagonist to be extremely cautious and affectionate.
