The Kyushu Continent is divided into four major kingdoms: Eastern Qi, Western Qin, Southern Chu, and Northern Yan. Jiuzhou has experienced ups and downs in troubled times, and Kyushu has been scattered. Only the four major families of Qin, Chu, Yan, and Qi remain standing in this desolate and chaotic world. The ancients said that Western Qin and Southern Chu were almost half separated, and Northern Yan and Eastern Qi had a deep friendship. In the ups and downs of the troubled times, Western Qin and Southern Chu had good relations to fight against the powerful Yan Qi in the north. In AD 12, the Western Qin royal family fought for the throne and had an enmity with Southern Chu. Qin Xuqi, who took the throne of Western Qin with the help of Northern Yan, wanted to show his favor to Northern Yan and married Yanyang, Princess Anyang, the daughter of Prince Heng of Northern Yan, as his concubine. In 24 AD, Qin Xuqi, the king of the Western Qin Dynasty, and Prince Yi jointly defeated the ethnic minority tribes in the northwest, and once again turned against the Northern Yan. In order to re-alliance with Southern Chu, Western Qin sent Liancheng, the eldest son of Western Qin, to Southern Chu as a sign of the alliance's sincerity.
At the same time, Emperor Yan of Northern Yan married Queen Gu of Eastern Qi, and Emperor Qi married Princess Yanzi, the emperor of Yan. The Kyushu Continent suddenly became turbulent, and rumors spread from all directions. Rumor has it that a daughter of the Chu family is the emperor and has the potential to unify the nine states.
The Queen of Nanchu gave birth to Princess Roujia not long ago. Unexpectedly, the midwife accidentally reported the princess to the daughter of the Prime Minister of Chu. The real Princess Roujia, Chu Muran, met a young man in green clothes in the breeze and drizzle in the Prime Minister's Mansion when she was young, and the young man left quietly.
Can Chu Muran, the real princess of Southern Chu, and Qin Liancheng, who is still alive as Emperor Ming, turn the tide and ascend to the throne of Western Qin? Who is responsible for the ups and downs of the three rumored princes of Western Qin? Can Emperor Beiyan and Princess Roujia regain Eastern Qi? Queen Qi Yanzi is willing to kill her?
