In the Era of Cataclysm, the world changes and spiritual qi revival begins. Beasts and livestock across the globe turn into demons, their bodies swelling as their sharp claws and scaled armor grow harder than alloys. Ancient primordial demon beasts also break free from their seals, becoming even more powerful. The demon beasts expand relentlessly, hunting humans. Cities fall one after another, and the territory of civilization shrinks at a staggering pace.
In humanity's hour of need, reclusive cultivators emerge from hiding. Hundreds of schools, including alchemy, swordsmanship, body refinement, and talisman arts, display their powers, only to suffer defeat after defeat. The laws of the world have changed: no matter how diligently humans cultivate, their physical combat strength will always be inferior to that of demon beasts. Even ordinary demonized beasts can withstand spells head-on, while ancient primordial demon beasts can tear through spell barriers and destroy magical treasures. Countless Dao lineages are wiped out and their legacies lost. Only the Beast Taming lineage survives.
The path of beast taming does not seek to have humans fight alone. Instead, it uses soul contracts to tame exotic beasts and fight demons with beasts. Pet beasts charge into battle while beast tamers coordinate, empower, and support them from behind, making up for humanity's physical shortcomings. From then on, beast taming rises to become the world's only mainstream cultivation system. Humanity uses modern weaponry as its last deterrent to defend its settlements, while promoting the art of beast taming to everyone. All people raise pets, and anyone can become a beast tamer, raising powerful pet beasts to protect the last spark of civilization and prepare to counterattack and reclaim the fallen lands.
