After three days of relentless storms, Yun City Hospital surgeon Ji Qingyan watches patients turn into ravenous zombies as the apocalypse breaks across the world. Awakening wood-element powers and a hidden spatial realm fed by a spiritual spring, Ji Qingyan pulls Gu Jinfeng, a wounded special-forces soldier, inside to save him, only for their mingled blood to seal an ancient Soul Contract between them. Bound together and cultivating side by side, the two must fight through monster-ridden ruins and uncover what is really driving the end of the world.
