Eternal Ferryman: 20,000 Years of Civilization Watch

Immortality mechanism: When the protagonist Lin Mo participated in a quantum neural experiment in 2025, his consciousness accidentally became quantum entangled with the cosmic background radiation, and he obtained "probabilistic immortality" - he would be reborn at a random node in the timeline after each death, and retain all memories, but he could not actively control the time of rebirth. Civilization Accelerator: Lin Mo's brain is injected with the unfinished "Human Civilization Map" quantum model, and he can instinctively perceive the potential risks of branches of the technological tree, at the cost of experiencing a 72-hour memory chaos period every century. Time Anchor: Only when human civilization as a whole breaks through to Kardashev Type III civilization can Lin Mo end his reincarnation. One sentence summary: A mortal trapped in the amber of time spent 20,000 years of death and rebirth, dancing a dance of redemption on the edge of the precipice of the rise and fall of civilization—until he became the legend itself.
