A modern office drone transmigrates into the Tang dynasty as Li Xuanba, the so-called "Dumbest Prince in the Realm," wielding an 800-jin golden war hammer. He had planned to play dumb, lie flat, and coast through life, but his older brother Li Shimin keeps throwing him onto battlefields, into court, and into every whirlpool he wants to avoid.
When he's finally backed into a corner with nowhere left to run, the world discovers that this supposedly dim-witted prince's hammer can smash the Turkic cavalry and pave the way for the golden age of the Tang dynasty.
Traveling through collision history, the plot is passionate and worth reading!
