Part 3/8:
As the plan unfolds, humanity relocates to vast underground cities built near these colossal engines. Here, we meet Liu Peiqiang, a Chinese astronaut preparing for a mission to the Navigation Platform International Space Station. On the eve of his departure, he spends precious time with his young son, Liu Qi, and his father-in-law, Han Zi'ang, imparting knowledge about Jupiter and promising to return when Liu Qi can see the planet without aid.
As the years pass, disasters plague the Earth, turning its surface into an icebound wasteland. Flashing forward to 2078, we find an adult Liu Qi reluctant to adapt to life in this new world, grappling with grief and abandonment as the memories of his father haunt him.
