In the 313th year of Moli, Yang Yan established the Huan Dynasty, and the world called him "King Huan".
In the 515th year of Moli, Yang Cheng, the 14th monarch of the Huan Dynasty, succeeded to the throne. However, during the two years after taking the throne, he almost always wandered in beauty, and even heard the sound of sex from the curtains of the court. The Huan Dynasty, which had been prosperous for more than two hundred years, finally gradually fell into poverty under the rule of this mediocre king. Officials are increasingly corrupt, the people are in dire straits, and the world is in chaos.
In the 518th year of the Mo calendar, Guan Ruoqing, the ninth prince, led his troops into the fragile imperial capital and seized power in one fell swoop. The Ninth Prince loved the people like a son, was diligent in political affairs, and was deeply loved and trusted by the people. Half a year later, he was crowned the new emperor, established the Sheng Dynasty, and was called the "Sheng Emperor."
Due to his diligence, Emperor Sheng's official Ruoqing rarely came to the harem. He gave birth to a son only seven years after he became emperor, and the second prince was born four years later. The eldest prince is introverted and obsessed with martial arts, while the second prince is extroverted and obsessed with politics. The combination of the two can lead to the emperor, so the crown prince has not yet been named. Unexpectedly, the second prince was abducted by the enemy at the age of ten and disappeared. The eldest prince wanted to have good relations with another country, so he was handed over to another country as a "pawn exchange".
Three years later, Emperor Sheng, who was on patrol incognito, met the second prince who was begging and had amnesia. In the same month, the eldest prince returned to the court, and the whole country celebrated. Soon, the world will be at peace.
However, darkness lurked beneath this calmness. The second prince who only cared about having fun and ignored political affairs after his return, the eldest prince who became increasingly cold-hearted, the princess who made friends with assassins, the prime minister with ulterior motives... Everything was hiding murderous intent under the shroud of imperial power.
