Zongfan Iron Cage: I Made Muskets in Longqing

In the first year of Longqing, the Jingjiang Palace in Guilin. As soon as Zhu Bangyu opened his eyes, he became a criminal who would be escorted to Fengyang High Wall in three days. He lost his title, lost his backing, and still had an iron cage of vassalage hanging over his head - he was not allowed to command troops, he was not allowed to do business, and he had to apply for approval before going out of the city. Ignore others, this is a dead end. However, in his previous life, he was a scout and an engineer in the military industry. He also had a "Tiandao system" hidden in his mind: he was only given blueprints, not magic weapons. Gunpowder, muskets, bastions, and military systems had to be built by himself. While others listened to the sound of a matchlock gun, he determined the caliber, quantified the medicine, and tested each piece, turning a pile of scrap guns into an elite army that dared to confront Gutian's strong army. While others were trapped in a feudal cage waiting to die, he took advantage of Yin Zhengmao's 100,000-strong army to conquer Gutian. Granular gunpowder replaced bulk inferior medicine, queuing gun arrays crushed bravery in the mountains, geometric bastions nailed the border between Guangdong and Guangxi, and ocean-going ships brought back silver and grains one by one. From the sin sect awaiting death to the king of Nanyue who took charge of the army and established a vassal state; from a royal city under Duxiu Peak to the thousands of miles of waves in the South China Sea. The rules of the Ming Dynasty can trap ordinary clans, but they cannot trap a person who has standards, firepower and organization in his hands. Let's see how he broke the situation with firearms. During the Longqing era, he created another iron-clad country for China overseas in southern Xinjiang.
