Erased Young Man with His Roof

A young man whose name was deliberately erased burned 300 samples and shattered a whole room, just to make the world more "stable". After his death, the project was shut down, his colleagues were fired, and his name disappeared from all files. The only thing left is a mysterious number - LM-2044. Twenty-three years later, tenant Lin Yu discovered a tile that generated electricity on the landlord's roof. From then on, he followed a series of numbers hidden in daily life, tracing an eradicated technological genealogy: from the energy storage tank in the corner to the nuclear battery in the body, from wave energy at sea to photovoltaic stations in space. When the truth was peeled back layer by layer, he finally understood the young man's last words left in his memory: "Technology is ours, no one's secret." Some light has been blocked for twenty-three years, but has never been extinguished.
