Zhao Huaijin, the eldest son of the Yongning Marquis Mansion, returns from rebirth. The nightmare of his entire family being massacred in his previous life is still vivid in his mind. In this life, he is still a gentle prince on the surface, but secretly he joins forces with Shen Qingluan, a female general who has also been reborn, to set up a shocking chess game in the capital. The chief assistant Chen Boyuan is scheming, Jiangnan female conglomerate Liu Ruyan is both an enemy and a friend, and the commander of the Gyeonggi Guard Zhou Jingan becomes his sharp knife in the imperial army. Even Zhao Yuanlang, his concubine who rebelled against the enemy in his previous life, is attracted by him again. From the Marquis Mansion to the Court, from the border to the south of the Yangtze River, Zhao Huaijin worked step by step to accumulate power. When the time was right, he would take back everything that belonged to him - even the dragon chair.
