Become an Emperor Through Time Travel: I Have Three Thousand Beauties in My Harem

[Emperor] [Travel] [System] [Strategy] [Ancient Black Technology] Transformed into a sick prince who could not live for three days in Dajing, Zhao Chen was bound to the [Strong Country System] when he coughed up blood. Poisonous wine is on his pillow, powerful ministers are in front of his bed, and history books have decreed that he will die. He used local methods to make saltpeter, improved agricultural tools, and established the Royal General Academy. When all the enemies thought they were dealing with a cheating emperor of science and engineering, they were horrified to discover that what Zhao Chen was facing was never a cold weapon rebellion. The Taoist temple in central Sichuan sent geniuses who were brainwashed by "ancient methods", camel teams from the Western Regions spied on gunpowder formulas, and mineral specimens were hidden in wooden boxes at sea... A cross-continental "knowledge jihad" has already begun. Some people want to restore the country, some want to usurp the throne, and the most terrifying enemy wants to permanently tamper with the direction of civilization in this land. Zhao Chen stood in front of the furnace of General Academy and sneered: "Comparing with me on the science and technology tree? Behind me is the desire to win and lose that has been passed down from the ancestors of science students for five thousand years."
