I Sold 4 Billion Mines and Developed My Own Photolithography Machine

Before his death, Su Cheng, the coal boss, suddenly realized that he had spent billions to build a chip research institute, but in the end it became a trophy for his wife and brother. Even his son was not his biological son. He returned to 2006, activated the technology revitalization system, and had a full set of 90nm chip production lines in hand. Faced with the ridicule of everyone, Su Cheng made plans step by step. He decisively took action in the coal mine, founded Huachuang Technology, tackled chips and photolithography machines, and broke through the overseas technology blockade. In the past, everyone laughed at the coal bosses as unworthy of talking about rejuvenating the country through science and technology, until Su Cheng stood at the top of the industry and shouldered the burden of technological breakthrough with the tenacity of coal mining.
