Guo You, a brooding young man abandoned by his family, inherits a dilapidated “abnormal creature shelter” on the outskirts of the city. No one knows that this seemingly ordinary shelter is actually the entrance to an ancient “divine beast prison,” where countless beasts were sealed away. As the heirs of the great families unleash bloodshed across the city in a fight for the right to form contracts with divine beasts, Guo You discovers that the beasts sealed deep inside the shelter have actually chosen him as their master. They can sense that this young man is the only person in a thousand years with the talent to communicate with the “source of divine beasts.” Power struggles, schemes, sieges, betrayal... While forces of every kind go mad over the divine beasts, Guo You simply opens the shelter door in silence and lets out a primordial behemoth capable of devouring an entire city. He never makes the first move, because every trouble comes looking for him on its own. And when trouble turns into a pleasant surprise, all he has to do is sit in the shelter courtyard, sip tea, and watch his divine beasts trample his enemies underfoot.
