The Game Starts in a Steel Mill, and I Assist the Empress.

Chen Chuan, the director of a modern steel factory, accidentally traveled through time and became a "good-for-nothing son-in-law" in a small country in ancient times. Just as the empress ascended the throne, the treasury was empty and border troubles continued. Chen Chuan was bound to the [Great Steelmaking System] at the beginning. In a different world where modern civilization was hit by dimensionality reduction, he used a roaring steelmaking plant to build the Great Steel Wall that the empress swept across Liuhe. In the end, he counterattacked from a son-in-law to the "Steel Protector Prince" who dominated the world.
