[A condemned prisoner from the start, a fortress built in seven days, firearms sweeping the grasslands!]
Lin Yuan, a modern army staff officer, transmigrates during a military exercise to the third year of the Chongzhen era. He wakes up on the execution ground, owing three hundred shi of grain and set to be beheaded at noon!
He activates the Military Campaign System and receives a cement formula. He builds a star fort in seven days, stunning the border troops; three months later, he trains a new army whose firearms sweep away the Mongol princess Agula.
From a low-ranking border officer to the commander-in-chief of Xuanfu, from a cement workshop to a modern arms factory. Flintlock rifles, field guns, steam engines, railways... I'll use modern military industry to smash this rotten dynasty!
When Li Zicheng enters the capital and Chongzhen hangs himself, I place Princess Changping in charge of the regency and lead an army armed with firearms on a northern campaign to unify the realm. At last, I reform the government into a republic. Each of my four heroines takes charge of one branch, and steam trains carry us into a new age.
