An accident sends his soul transmigrating into the body of Li Shimin’s eldest legitimate son in the Tang dynasty.
Who would have thought his leg would be broken from the start? How is he supposed to keep having fun now,
let alone experience the customs and sights of the Tang dynasty
or meet all those wonderfully uninhibited young ladies?
