Chen Yan's Craftsman's Dream: Lin Yan's Firearms Legend

On a mysterious night, Lin Yan, a modern mechanical doctor, unexpectedly traveled to the Chenyan Dynasty in 1320, and the gears of fate began to turn crazily. When he first arrived in Monan, the blacksmith village where Lin Yan was located was massacred by the Tie Rong Army. His father gave his life in exchange for half a fragment of the "Illustrated Firearms" for him. The fragment contained unique secrets such as the forging process of the Xixia "Zhentian Lei" shell and the improved sketch of the base of the return cannon. From then on, Lin Yan embarked on the road of escape and counterattack. Relying on the knowledge from his previous life and the guidance of the "Firearms Catalog", he began to overcome obstacles in the ocean of technology. Taking advantage of the drop of Yinshan Waterfall, an improved hydraulic forging hammer driven by a three-stage water lifting device was designed, which greatly increased the efficiency of forging iron. The improved return gun used "gravel + tung oil solidified bombs" to shine on the battlefield, successfully repelling the Mongolian army's attack. However, the road ahead will not be smooth. The conservative Mongolian dignitaries and corrupt local officials regarded him as a thorn in their side and tried every means to suppress him. But Lin Yan did not back down, and he made allies such as enlightened Mongolian princes, Han intellectuals, and businessmen from the Western Regions. With their help, Lin Yan continues to break through himself. He improved Li cotton spinning technology, established the "Silk Road United Banknote", and issued "Silk Road Treasure Banknotes", disrupting the monopoly of the Semu Merchant Group. In the military, he also developed a "modular detachable crossbow", which greatly challenged the advantages of the Mongolian cavalry. A series of key battles. Can Lin Yan lead everyone to victory with his wisdom and technology? What major choices will he face on the road to personal growth? Should he establish a new dynasty or retire from the world?
