In 2089, the "Purple Mist Descent" sweeps across the globe. Half of humanity mutates into bloodthirsty "Bone-Eaters," skyscrapers become shattered ruins, and once-prosperous cities turn into wastelands where no living soul dares to venture.
Chen Mo, an ordinary college student struggling to survive among the ruins, is on the verge of death when Bone-Eaters surround him. At that moment, he unexpectedly awakens the "Apocalypse Cultivation System." His first mission, to kill a first-tier Bone-Eater, earns him not only the spiritual energy he needs to stay alive and the basic cultivation manual, "Qi Guiding Art," but also sets him on an incredible path from a nobody to an Immortal Venerable.
In the wasteland, resources are scarce and humanity is twisted. He keeps a low profile, using the System's "Disguise Mode" to play the pig to eat the tiger as he quietly develops within a survivor base. He searches for rare medicinal herbs to help Su Qingyue resolve the base's predicament, helps Lin Xi's ability-user squad break through a beast tide, and comes to Chu Mengyao's aid when she gets caught up in a family feud. While everyone thinks he's merely a survivor with a little strength, he has already quietly broken through to Foundation Establishment and the Golden Core stage. Ye Zihan, who holds an ancient inheritance, also reveals to him the shocking secret behind the Purple Mist and the Bone-Eaters.
From the struggle for supplies at Dawn Base, to the search for traces of immortals in the Kunlun ruins, to the interstellar war against the Bone-Eater Starfolk, Chen Mo wields the System as his blade and cultivation as his shield, carving out a path through the wasteland strewn with corpses. He must not only protect the women by his side, but also lead the surviving humans in rebuilding civilization from the brink of destruction. In the end, he will ascend to the rank of Immortal Venerable and let the light of China's dragon veins shine over this desolate land once more.
