I Risked My Life for Science, and Now Everyone's Begging Me Not to Die!

Zhou Xingfan is a transmigrator who transmigrated to a parallel world. Before even two years had passed, he developed heart disease and spent three years bedridden. Just as he was about to die, he activated the System, which lets him stay alive by doing scientific research. He recreates a 2-nanometer lithography machine, stunning the professors at the research institute. Then he develops 1-nanometer lithography, turning the whole world upside down with the work of a young man on the verge of death!
