Li Kuan, a modern social beast, accidentally transformed into the leader of the "Four Pests of Chang'an" during the Zhenguan period - King Li Kuan of Chu.

That same year, when Li Shimin traveled around the world on a steamship, he discovered that his son had established the "New Tang Federation" in America: "This bastard actually placed the mahjong table in Rome!"
