Li Nan, a social beast, transformed into the tragic King Jing of the Tang Dynasty. He knew full well that the original owner would end up being involved in the tragic death of his heir, and he vowed to live to the end. He refuses to take sides, hides his edge, pretends to be mediocre, and is determined to be a transparent waste prince. But the more he tried to keep a low profile and avoid trouble, the more he was accidentally pushed to the forefront. All forces frequently misinterpreted his "cowardice" as a far-sighted plan, and a life-saving drama that was forced to be conspicuous began.
