In 2023, Lin Zhou, leader of the chip research team of the Chinese Academy of Sciences, suffered a heart attack on the eve of the breakthrough of the 3-nanometer process. When he opened his eyes again, he returned to the attic of the Shanghai stock market in 2000. Outside the window are the Millennium fireworks, and the TV is broadcasting China's WTO accession negotiations, while in his mind are the technological blueprints, patent traps, and history of blood and tears for the semiconductor industry in the next twenty-three years. "When the chips are soldered, the systems are piled up." Taking this as his credo, he started by dismantling old microcontrollers, persuading old technicians to come up with photoresist formulas, and wrote a simple operating system in assembly language in an urban village. He managed to attract an investment of 500,000 yuan despite being infamous. Faced with TSMC's ridicule, he led the team to tackle difficulties step by step. In the end, "Loongson" broke the x86 monopoly, the "Kirin" system forced Google to modify the open source agreement, and the China-led RISC-V architecture became one of the three major chip ecosystems in the world. Looking at the blue light of the 28-nanometer domestic DUV lithography machine in the laboratory, Lin Zhou smiled and said to the gray-haired old engineer next to him: "Back then, you said that I drew children's graffiti on the chip image. Do you believe it now?" This is the story of a man who carries the memory of the future and plants trees on the barren technological soil to shade China.
