Zhang Jingshan, a senior civil engineer, dies while helping rescue workers after a major construction-site collapse. When he opens his eyes again, he has been reborn in the late 1980s, not long after starting his career.
Back then, monitoring equipment was scarce, and the only way to assess geological hazards was through field observations and experience. Carrying the painful memories and hard-won lessons of countless accidents from his previous life, he knows exactly where one engineering crisis after another will erupt over the coming decades.
He cannot prevent every geological disaster, but he gives advance warnings whenever he can. Some hazards still occur, but the warnings allow everyone on the work crews to get to safety.
From mountain roads, tunnels, and bridges to permafrost on the plateau, urban excavations, and subway projects, Zhang Jingshan devotes himself to frontline infrastructure work, struggling to uphold his principles amid deadline pressure, cost disputes, and geological risks. He records every hazard he has witnessed and every lesson he has learned in his notebooks, then passes on a lifetime of engineering insight to the next generation in his old age.
This is the rebirth story of an infrastructure worker. He does not seek to defy fate, only to keep projects safe and protect every precious life.
