A First-Class Prince of the Tang Dynasty

The eldest brother died young and passed away suddenly. On his way back to his hometown, Li Xuan traveled back to the Tang Dynasty in grief! Unexpectedly, Li Xuan, who was in a coma, met the unlucky Li Shimin who had just been robbed by the Turks by the Weishui River. With the exact same appearance, Li Xuan became Li Shimin's younger brother and inherited the title of King of Qin! "Brother, let's search for things!" "No, my country is unstable, my treasury is empty, my people are not rich, and the Turks, the Western Regions, and Gaoguli are thorns in the road, and domestic affairs are not settled, so I really have no time!" "This is such a small thing! I have just developed a new weapon in my laboratory. It has a long range and is very powerful. Please wait for me for a few minutes!" A few days later, Li Shimin and Li Xuan looked at the huge map of the Tang Dynasty, frowning and really couldn't figure out who to fight. Li Xuan suddenly said: "Brother, I heard that there is a small country named Byzantium across the sea..." Li Shimin was delighted: "The emperor's brother has won my heart!"
