Lin Feng, a double academician, accidentally traveled through time and became a "waste worker" at the Inner Mongolia Steel Plant in 1978. This Huaqing genius, who was sent to the frontier in the name of "academic fraud," was actually the victim of a major material discovery stolen by foreign scholars. When Soviet experts openly insulted Chinese industry with steel slag, he resolutely tore off the disguise and launched a counterattack with a pile of waste materials and indigenous steelmaking technology. From improving converters to developing special alloys, from technological breakthroughs to international recognition, under the protection of factory directors who were veterans of the War to Resist U. S. Aggression and Aid Korea, he led Chinese industry to break through technological blockades, embrace the wave of reform and opening up, and create China's industrial glory. This is a counterattack legend about hard-core technology and passionate struggle!
