Lord of the Nation: I Became the Largest Arms Dealer

(The setting is not set well, it is unfinished, don't come in.) The game "Civilization Progress" is a game developed by the Universe Alliance, which allows civilization to evolve in the game. Each lord starts with five square meters of territory, and Zhang Yi is rewarded with 10 matchlock guns at the start, starting his journey to the game's hegemony. Matchlocks, breech-loading guns, machine guns, cannons, aircraft, and tanks will gradually appear in the game as civilization evolves. The vast game space is where civilizations from all over the universe will collide.
