After the War of the Five Kingdoms, the Qi State unified the world, and the other four countries became small dependent countries. The Emperor of Qi is already old, and several princes are ready to make a move. Whether it is the humble King An or the insignificant King Min, they are inevitably involved in this power dispute. The position of the East Palace is high, and people's hearts are uncertain. Fortunately, the turmoil in the court after the victory has not been so obvious, but there is still an undercurrent. The old emperor was suspicious and never established the crown prince's position. The ministers were busy standing in line for this purpose all day long. All the princes are also secretly developing their own power. Yulin Valley has naturally become the target of various forces competing to win over.
Yulin Valley is located in the mountains and forests dozens of miles outside the capital. Its medical skills are unparalleled in the world and have won the hearts of the people. People in the valley treat people who come to seek medical treatment free of charge, and they can also take people as apprentices and teach them medical skills and martial arts. But there is a rule in the valley, regardless of the origin of the visitor, you will be treated as an ordinary person if you are a prince, general or minister after entering the valley. Those who want to leave the valley after learning must sever ties with Yulin Valley. If they cause trouble to the valley or have other intentions, they will be killed. Some people say that Yulin Valley is philanthropic and helps the world. Some people say that Yulin Valley is ruthless and kills countless people.
The master of Yulin Valley is known as Young Master Nanqi. Although he is a young master, he is actually a twenty-eight-year-old girl with stunning appearance and unparalleled medical skills. She is dressed in white clothes and looks like an immortal. Everyone said that Master Nanqi was half a god, saving all sentient beings, and half a demon, seducing souls. Nanqi also keeps a Mengze beast, which looks like a cat and is named Shiqi. It can speak human words, become invisible, and has boundless magical power. Therefore, during the battle for the right to inherit the throne, Yulin Valley fell from a paradise into a turbid imperial court.
