Ming Dynasty: Father and Son Penetrated the Gunboat Technology and Swept Wanli

Lightning struck the Forbidden City, and Lin Zhiyuan, the vice dean of the engineering department, and Lin Qiyuan, the son of the UP master, traveled through the Wanli period for twenty years and became poor children. The two brought a 2TB library with them. They first laid cement to block embankments and replaced the fields, then built a hydraulic cotton gin and a Jenny machine. They produced hundreds of kilograms of yarn a day, creating a storm in Songjiang Bu City. Faced with the encirclement and suppression by the Japanese pirates, the Weaving Bureau, and the Neo-Confucian school, the father and son entered the imperial examination by "checking things", changed the match rope to rifling, upgraded the cast iron boring machine, and the 6-inch "Eclipse" gun had a range of over 1,000. In the Battle of Chongming, the chain bomb broke the sail, the three cannons at Longtun in Bozhou collapsed the Shimen, and the Japanese iron artillery team was covered with shrapnel under Pyongyang City, reducing the dimension and crushing it. By the way, stocks were issued, silver coupons were issued, and waste mine taxes were issued to leverage the Ming Dynasty's finances. Her father was promoted to a minister in the Ministry of War, and the heroine Shen Zhiwei became the richest man in civilian life, but she refused to fall in love with him. Three wars and thirteen consecutive technological leaps turned the late Ming Dynasty into a semi-industrial empire; the solar eclipse was out, the east was white, the father and son set sail, and the stars and the sea were waiting to be continued.
