The gray-green fog swallowed up the sun, and for three years of "Silent Catastrophe", only ruins and predators remained in the Jianghuai Plain. The superpowers crack the earth and become kings, while mortals become consumables; the refugees live in the putrid mist, and even clean water can change their lives. Li Mu, a former civil engineer, was separated from his family during the disaster and awakened the power of "Earth Control". The old pocket watch with his family's names engraved on his palm is the bottom line for him not to be alienated in the apocalypse - he doesn't want to be a perpetrator, he just wants to protect the refugees and survive. But the top supernatural organization "Blackstone Brotherhood" coveted his abilities and burned down the settlement he protected.
