Gun Regulations State: the Legend of the Artillery God in the Late Ming Dynasty

Can a Hongyi cannon rewrite the fate of the Ming Dynasty? In the third year of Chongzhen's reign, Yuan Chonghuan was defeated, Kong Youde planned a rebellion, and Xu Guangqi's Western artillery became the last hope to save the crisis. Shen Yanzhi, a scholar carrying a gun and compasses, and a close disciple of Xu Guangqi, accidentally got involved in a game that changed history on the night of the cannon test at Baoguo Temple - he used the telescope to calibrate the angle of 30 degrees, but he did not know that he was aiming at the last way out of the Ming Dynasty. When the flames of the Wuqiao mutiny ignited Dengzhou, when the blueprints of the Hongyi artillery fell into the Later Jin Dynasty, when the Qingliu of Fushe and the remnants of the eunuchs were fighting in the court, this Shujishi who was proficient in Western arithmetic, holding "Fire Attack the Key Points" in his left hand and the Miao knife in his right hand, walked a path of "defending the country with artillery and saving the country with wisdom" between the secret ticket numbers and the Hongyi artillery list.
