The Han Palace Case

Wu Shen, an obscure swordsman, transmigrates to a Great Han dynasty that is familiar yet not quite the same. He originally plans to rely on his swordsmanship to become a dashing, gallant swordsman, but by chance he meets a group of people and gets caught up in the affairs of the Huaiyang Prince's palace. Under the care of the Huaiyang heir, whose gender is difficult to discern, one case after another lands before Wu Shen, drawing him ever deeper into law enforcement until he reaches the capital, Chang'an.
