In 2726, a global catastrophe strikes, and Jiang Chen awakens an apocalypse survival system. He builds a secure fortress, shelters survivors out of goodwill, and establishes fair rules for survival. Together with Wen He, an immune nurse with special abilities, and Shen Xi, his powerful second-in-command, he repeatedly repels hostile forces seeking to seize their abilities. Jiang Chen then comes to the rescue of the besieged Qing Su Command, gaining military support and scientific resources. Eventually, the system unlocks the power to purify the entire world, wiping out the threat of mutation. After the crisis, everyone joins hands to cultivate the wasteland and build a peaceful, stable new city for humanity.
