Busy, Fighting for the Throne

Wang Meng traveled through the Middle Ages and became the Grand Duke of Clyde of the Plain Country. Since you can't live a life of salted fish, let's do something serious. The goal is nothing more than to dominate the world and sweep across the world. Kill the king and depose the emperor, destroy the country and practice the noble title.
