Lord: I Build the Supreme Civilization

After an accidental time travel, Ryan became a baron on the bitter cold border, lacking food and clothing, and surrounded by foreigners. Fortunately, he awakened to the civilization development system. As long as you promote the development of civilization, you can obtain civilization points and exchange them for technology. Exchange [Basic Power Generation] technology, and the territory will light up the night from now on. Exchange the [Arquebus] technology and soldiers enter the age of firearms. Exchange [Fighter] and [Destroyer] technologies to suppress them across the sea, land and air. … Some years later. Ryan initiates all-out war. The mechanized troops advanced rapidly, and resistance along the way was quickly cleared. The enemy soldiers knelt down and surrendered, and saw a copy of "Ryan's Struggle" flying from the tank. "I don't have time to accept your surrender." "Report to the Prisoner's Department yourself."
