Reborn as the Crown Prince, Surrounded by the Empress from the Start

The protagonist, Qin Hao, is a military expert from Huaxia with an extensive knowledge of modern warfare history and military theory. By chance, he transmigrates to a fantasy world resembling the Warring States period of ancient times and becomes the crown prince of Daxia, a small nation teetering on the brink of collapse. To the north, the barbarian Bei Mang tribes watch like hungry tigers; to the west lies the mighty Qin Empire; to the east stretches the vast, endless Tianfeng Sea. At home, powerful ministers hold sway and plot rebellion. And his “legendary” father has just died, leaving him with a terrible mess and... three dowagers of different ranks and backgrounds.
