The Iron Moon Dyes the Light: the Era of Manganese Steel in Western Hunan

Materials scientist Zhang Tan traveled to western Hunan in the late Ming Dynasty. The first thing he did was not to make guns or cannons, but to make a pair of iron trousers and armor for the bride who was deprived of her first night by the chieftain. Dignity has become the first forgeable commodity. From then on, the fire never goes out. From a blacksmith shop to an industrial system; from a corner of western Hunan to defeating the Manchus and escaping to Japan; from a troubled time to an industrial country. While Western scientists were still thinking hard, the Chinese children's book "One Hundred Thousand Whys" had already given the answer. After being translated, it was banned by the Pope.
