Late Ming Dynasty: My Knowledge Can Be Upgraded

Lu Qiming traveled through the late Ming Dynasty and became a military household in Shaanxi who was about to starve to death. There was only a house slave who was also dying and three moldy bran dumplings beside him. Outside is a thousand miles of red land, rogue bandits are like combs, and officers and soldiers are like grates. In a desperate situation, a knowledge base called [Reverberation of Civilization] awakened in his mind. But there are no complete drawings here, only incomplete principles. Every bit of knowledge extracted was accompanied by severe pain as if the head was exploding. He must use practice as fuel to light up this rugged technological tree. From using physics knowledge to make the first hunting trap, to using chemical principles to purify the first drinking water; from leading dozens of refugees to reclaim wasteland, to establishing a modern legion that scares the enemy. When he pointed his flintlock at the cavalry outside the pass, and when his warship crossed the ocean... The world was shocked to realize that the spark ignited by a traveler was enough to start a prairie fire.
