In the last years of the Dayan Dynasty, there were separatist vassals and towns, refugees were everywhere, and powerful enemies were lurking around outside. As soon as the seventeen-year-old prince Zhao Chen ascended the throne, he became the "last monarch" destined to perish. The court is empty, but there are loyal ministers but no strong army. The treasury is empty and it is difficult to support the military pay. The countdown to the country's subjugation is urging people to die.
In a desperate situation, Zhao Chen accidentally unlocks the "Wanjie Arms Mall" - with a tap of his fingertips, he can buy repeating rifles to suppress cavalry charges; accumulate reputation, which can be exchanged for mortars to blast enemy fortified cities; when resources are sufficient, he can even summon armored vehicles and fighter jets to rewrite the rules of war in the cold weapon era.
He is no longer a puppet monarch who is at the mercy of others: he uses a sniper rifle to intimidate the rebellious vassal king, relies on a batch of machine guns to rebuild the elite forbidden army, and uses an artillery array to drive back the prairie cavalry. From quelling civil strife to sweeping through surrounding countries, from building a modern army to establishing a global colonial system, the last emperor of the past will eventually use steel and artillery to pave an iron-blooded road from the edge of subjugation to the unification of the world in another world.
