Earth is on the brink of collapse. The Federation conceals the truth behind the depletion of psionic energy, while resource wars and class oppression push the world toward the abyss. Lin Xiuyuan, once an ordinary office worker in his previous life, unexpectedly transmigrates to a wasteland where people are exiled. There, he awakens a cultivation System: daily sign-ins can reward him with techniques or resources, but failure will cost him years of life. Alone and without help, he reveals his abilities during a psionic-energy riot, drawing the Federation's pursuit and the exiles' suspicion. He proceeds cautiously, hiding his identity, yet the lure of power puts his humanity to the test. His partnership with Su Wanqing, a brilliant researcher, is fraught with tension. She is rational and proud, yet softhearted, and repeatedly warns him not to lose himself. When the Star River organization reveals the truth about evolution to a higher dimension, Lin Xiuyuan faces an ultimate choice: overthrow the Federation or sacrifice a few. Caught between a clash of beliefs and torn emotions, can he rewrite the rules of the apocalypse?
