Tampering with Destiny: the Retrograde Man in the End of the World

In the third year of the apocalypse, Li Chen unexpectedly awakened the "Fate Tampering System", which was able to tamper with the probability of events and change fate against the will of heaven. But every tampering triggers a butterfly effect - zombies evolve, natural disasters come, the world correction mechanism is activated, and crises follow like a shadow. In order to survive, he was forced to team up with survivor Lin Wei, hacker Zhang Heng, and medic Zhao Yu to struggle forward in the ruins. As the hidden mission of the system "Tracing the Origin" unfolds, Li Chen discovers that the truth of the apocalypse is closely related to his previous life as the CEO of a gaming company. The AI ​​matrix in the company's underground base regards humans as evolutionary experimental samples, and he is the key variable. The Blood Wolf Gang's mechanical legions, probability storms, memory deprivation and other crises followed one after another, and every choice was accompanied by sacrifice and betrayal. In order to resist fate, Li Chen continued to struggle amid system betrayal, teammates dying, and memory annihilation. In the end, he faced the mother body, launched the ultimate modification at the cost of his own death, and restarted the source code of the apocalypse. In the alternate reality, the apocalypse has ended, but Li Chen has disappeared from all timelines, leaving only the team in memory of the "missing hero" in front of the monument. In the cracks in the data, the afterimage of his consciousness is still flickering, hinting at the unfinished mission and the hidden conspiracy... This is a story about fate's struggle, moral choices and self-sacrifice. When the price of tampering with destiny is the entire world, the retrograde will eventually face it - is he the biggest variable?
