In the first year of Chongzhen, Zhu Youjian opened his eyes and faced the situation of empty treasury, rogue bandits, and the whole dynasty hoping that the new king would die soon. When the civil servant group united with the Houjin smuggling caravan to force the palace to depose the emperor, this time traveler with a background as a military engineer directly threw the flintlock blueprint and the new policy of the Salt and Iron Government at the court meeting. He supported businesswoman Su Wantang to establish an intelligence network, used Sun Chuanting to organize the army, and reinforced the Ningjin defense line with cement. When Zhou Yanru and hundreds of officials knelt down to beg for the removal of the new law, Zhu Youjian sneered and pulled out the red cannon - since the Manchu Dynasty wants me to die, I will overthrow this man-eating Ming Dynasty first!
