I Cultivated Immortality Through Science and Technology in the Late Ming Dynasty

Gu Mingchuan traveled back in time to the late Ming Dynasty with the memory of Huang Maple Valley's weapon refining, and became the son of a blacksmith in Daxing County. In his previous life, he had cultivated hundreds of entry-level magic weapons, and could draw the pattern of a green leaf with his eyes closed; in this life, his spiritual energy was thin and his spiritual materials were completely gone. It took him seventeen years to build a degraded version of the weapon refining furnace. Then a bolt of lightning struck the workshop, and the furnace started to work. The discovery that thunder and lightning can replace spiritual power makes everything different. In the spring of the 17th year of Chongzhen's reign, Li Zicheng entered Beijing, and the Qing army knocked on the pass. While Gu Mingchuan was repairing weapons for Dashun's army in order to gain a foothold, he also used a refining furnace to temper steel that was far ahead of this era. Hydraulic forging hammers, seamless steel pipes, rifled rifles, pure oxygen converters... A new industrialized city rose from the ground in the cracks of war. The priests of the Holy See came to the door following the fluctuations of spiritual power. The Manchu and Qing cavalry were still struggling in the quagmire of Jingdong, and the drawings in his hand had already drawn generators and electromagnetic induction. This is the story of a weapon refiner who distorted the technology tree in the end of the Dharma era. Amid the roar of steel and steam, the death knell of the old order is tolling.
