Those who were lucky enough to survive the catastrophe came to call their original planet and the distant alien world the Sun Wheel and the Moon Wheel: two overlapping yet independent spaces.

As the two spaces connected, powerful beasts poured through in an endless stream. Humanity's conventional weapons could no longer stop the ever-evolving monsters.

As the catastrophe unfolds, the protagonist, Xu Heng, grows stronger step by step and leads the surviving clans in resisting the beasts. What stirring tales of courage and compassion will unfold along the way?
