In the twenty-seventh year of Jinghe reign of the Dayin Dynasty, the late emperor suddenly died, leaving behind the eight-year-old prince and the vacant imperial power. Prince Jing Xiao Jue, who had great military exploits and dominated the government, was promoted to the high position of regent as an imperial uncle and took charge of the government on his behalf. Above the court, he was the "half of the sky" who ruled the world with a cold, decisive and iron fist. The courtiers either feared his power or respected his abilities. In the palace, he was the "Uncle Jue" who the young emperor Xiao Chengyi relied on and feared. He was also an unfathomable "powerful official" in the eyes of the late emperor Shen Weilan.
Shen Weilan, once a noble daughter of a well-known family in Beijing, once entered the palace and became the queen, but after the death of her husband, she became a "widow queen" who had to rely on imperial power to protect the young emperor. Between her and Xiao Jue, there was the kindness of the late emperor, the rules of the royal family, and even a secret past that no one knew about when they were young. When the undercurrent of power in the court surges, the vassal king is spying on the throne, and the relatives are trying to seize power, the nominal "uncle and sister-in-law" have to form a fragile alliance and work step by step in the turbulent power chess game.
In the name of "Prince Regent", he used thunderous means to clear obstacles, but when he was alone late at night, he took off his armor, revealing his unknown fatigue; she guarded the palace as the "Queen Mother", gentle and restrained, but when no one was around, she held on to the hairpin with hidden edge, fighting for her son and herself to survive. Power is the best catalyst and the strongest poison. When the alliance gradually deteriorates, and temptations and temptations breed in the shadow of the palace wall, can they face each other's deep-seated desires and emotions while preserving the country and the young emperor? And how will the past buried by time set off new stormy waves?
