This book has no System, no golden finger, and not many wish-fulfillment moments. Everything is fairly realistic. The protagonist is neither a genius nor all-powerful.
Chen Hao inexplicably transmigrates to Jing State. Fortunately, his original self was the second young master of the Duke of Chen's household. Though born to a concubine, he is deeply favored by the Duke of Chen, and his maternal family is a wealthy Jiangnan clan worth a fortune.
