Li Changge, a young man from modern times, unexpectedly transmigrates to the prosperous Tang dynasty during the Zhenguan era. He becomes Li Shimin's legitimate imperial son, raised in the home of the God of War, Li Jing.
In his previous life, he talked back to Li Shimin and refused to return to the imperial family, so he was thrown straight into the Dali Temple prison.
After transmigrating, Li Changge obtains a Fortune Pouch System.
During a war in the north, Li Changge is still locked away in prison, a thousand miles from the front lines. Yet one fortune pouch turns the tide, transforming defeat into victory and making the Tang dynasty's might resound across the world.
No matter how desperate the situation, opening one of Li Changge's fortune pouches can resolve the crisis, avert danger, and even turn defeat into victory.
And the one who makes all this happen is the eldest son of the Duke of Weiguo, locked away in prison, and also Li Shimin's legitimate imperial son raised in Li Jing's household.
