Shen Qingci, a doctor who lives in seclusion in the south of the Yangtze River, possesses peerless medical skills, but carries an unknown bloodline from the previous dynasty. When she tried to uncover the mystery of the "Black Butterfly Heart-Eating" epidemic, she fell step by step into a huge vortex of conspiracy - the mysterious sect "Xuanming Sect" reappeared in the world, and court officials died suddenly one after another. Her encounter with the commander of the Jin Yiwei Xie Wuwu was both the redemption of fate and the beginning of disaster.
Xie Wuwang, the cold-faced commander of the Jinyi Guards, holding a broken saber, is in charge of the world's prisons. He originally thought it was another ordinary turmoil in the world, but during the investigation, he discovered that this conspiracy went directly to the foundation of the court, and was closely related to the family blood feud that had been buried in his heart for many years. When he gave up his official seal for her and became the enemy of the entire martial arts world, he realized that some beliefs were more important than loyalty to the emperor.
From the apricot groves in the south of the Yangtze River to the evil plague in the Miao border, from the fog in Dongting to the wind and clouds in the north of the Great Wall, the two work together to uncover layers of mysteries:
· Why is the strange epidemic related to the lost magic?
· Why is the true identity of Xuanming Cult Leader so shocking?
· What is the connection between the treasures left by the previous dynasty and the national destiny of the current dynasty?
· What secrets of heaven are hidden in the twin powers of ice and fire?
When the world's common people and personal love and hatred are placed on both ends of the balance, and the orphans of the current dynasty and the sharp swords of the current dynasty fall in love with each other, can they keep their true feelings and break out of the situation in the treacherous world of rivers and lakes and court affairs?
This is a desperate battle involving medicine and killing, loyalty and betrayal, restoration and protection. In this blood-stained picture of mountains and rivers, there is only a touch of celadon, which has survived the disaster and witnessed the sincerity and unrepentant affection in troubled times.
