Counterattack from a Poor Family: I Use Technology to Level the World

There was an explosion in the laboratory, and Luo Yufeng, a man from 985 Science and Engineering, transformed into a gangster from the border town. As soon as he opened his eyes, he was blocked by a creditor demanding a debt of twenty taels. He was followed by two silly brothers and a debt-paying girl who was scared to death! In troubled times, the emperor is fatuous, the north and the south are moving, refugees are everywhere, and human lives are worse than dogs! The original owner is a gambler and has enemies all over the place. This start is simply hellish! Fortunately, my golden finger is mathematics, physics and chemistry! Coarse salt mixed with sand and sold at exorbitant prices? He purifies the snow-white refined salt using local methods and earns a fortune every day. He can even build a workshop after paying off his gambling debts! Is the plague rampant in every room? He refined penicillin, instituted quarantine, saved thousands of people from fire and water, and gained massive popularity among the people! Are the Beimang cavalry fierce? He made flintlocks, forged cannons, improved black powder, and used firearm arrays to teach barbarians how to behave! Suppression from the imperial court and separatism among the heroes? He mobilized teams and built base areas, used engineering thinking to build infrastructure, used chemical knowledge to strengthen the military industry, and used historical perspective to determine strategies! From a gangster in a border town to the overlord of one side, from avoiding war to heading north to fight against the enemy, Luo Yufeng relied on his knowledge of mathematics, physics and chemistry to fight his way through this troubled world! What you owe me, pay back double! Those who bully me, plow the court and sweep the holes! Beimang wants to fight? Destroy! The court wants to suppress? Opposite! Let's see how men in science and engineering use science to break class stereotypes, unify divided mountains and rivers, and establish a new dynasty where everyone has food to eat and clothing to wear! When modern science collided with the troubled times of ancient times, who would have thought that it would be a bag of refined salt, a bottle of gunpowder, and a subject of mathematics, physics, and chemistry that would change the world?
