A First-Rank Prince of the Tang Dynasty

His eldest brother died young, passing away suddenly. On his way home, Li Xuan transmigrated to the Tang dynasty in his grief! As it happened, while unconscious by the Wei River, he encountered the unlucky Li Shimin, who had just been robbed of everything by the Turks.

Their identical appearances made Li Xuan Li Shimin's younger brother, and he inherited the title of Prince of Qin!

"Brother, let's study the natural sciences!"

"I can't. My empire is unstable, the treasury is empty, and the people aren't prosperous. The Turks, the Western Regions, and Goguryeo are all a handful, and domestic affairs are still unsettled. I simply don't have the time!"

"Those are all minor issues! I just finished developing new weapons in my lab. They have long range and great power. Give me a few minutes, brother!"

Some days later, Li Shimin and Li Xuan stared at the vast map of the Tang Empire, frowning as they struggled to think of anyone left to fight.

Li Xuan suddenly said, "Brother, I hear there's a small country called Byzantium across the sea..."

Li Shimin was overjoyed. "You understand me well, dear brother!"
