In the second year of Chongzhen, after the Tumubao Incident, the Ming army lost all its elite troops, and the Oala cavalry was eyeing them. The soul of modern veteran Zhao Yan traveled through Zhu Qi Town. When he opened his eyes, he saw a desperate situation where the army was pressing down and the ministers were panicking. He has no system and no golden fingers. He only has a body with military training, a mind full of modern tactical thinking, and the "August 1st Bar" rifle (30 rounds of ammunition), a small diesel generator and the "Small Weapons Maintenance Manual" that he accidentally brought in when he traveled through time.
The game started with a dead end: Oala's pioneer Saikan Wang led 3,000 cavalry to attack the imperial camp. At the critical moment of life and death, Zhao Yan raised his hand and fired - the Saikan King fell off his horse in response, and Oala's formation was in chaos. He tore off his dragon robe and shouted to the stunned Ming army: "Want to live? Use this thing with me to teach the barbarians what 'firepower density' is!"
Breaking the situation depends on thinking: firearms are not plug-ins, but "the key to breaking the system." He used firearms to form the "Shenji Battalion Demonstration Team" and taught Qi Jiguang the "alternating cover" tactic; he used generators to demonstrate "energy conversion" and inspired practical learning in the Ming Dynasty; he used the "National Revenue and Expenditure Account" to visualize financial collapse and force the civil service group to face the truth. Hai Rui went from "opposing strange and cunning skills" to becoming a "sword of auditing", Qi Jiguang went from "traditional famous general" to "Father of the New Army", and Xu Guangqi went from "empty talk about investigating objects" to setting up a "Investigation Institute" to study firearms. In the collision of firearms and thinking, all the characters break away from historical labels and bloom complex arcs.
The endgame lies in the system: When the new army swept across Mobei and the finance turned around, what the readers saw was not "crushing with guns and cannons", but a modern soul using "limited resources + systematic thinking" to let the decayed empire learn to "fight" again.
