A torn volume of "Records of Strangers in the Song Dynasty" records a brilliant and beautiful Wulin Commander named Song Yuanchao who was dubbed a "rebellious minister and traitor".
"In the fifth year of the Taiping and the rejuvenation of the country, the Wulin Division led Song Yuanchao, named Yuhe. He was an elegant and upright person with unrivaled intelligence. He was proficient in poetry and prose, and had unparalleled martial arts skills. He created the 'Heluo Sword Technique' and was famous in the world. However, he was so talented, but he was willing to work as a tiger, colluding with the Jin people, and intending to subvert the country. In the end, he was executed in Tokyo, and he was truly a sinner for the ages..."
These few lines of words cast a stone in Le Yiran's fate. She was born through the womb with the memories of her previous life since she was a child. She was born as the daughter of Duke Ding. Because of her extraordinary intelligence, she was raised in the palace by the Queen Mother. For sixteen years, she has been searching for the meaning of her rebirth across time and space.
Until that day, she saw this record in the ancient book given by the Queen Mother. There are contradictions everywhere in the words: Why would a person who was praised as "elegant and upright" betray the imperial court? Why was the peerless talent who created the world-famous "Heluo Sword Technique" so easily captured and executed? What confuses her even more is that the special symbols hidden in this record are surprisingly similar to some ancient cryptography she learned in her previous life.
The gears of fate turned quietly when she decided to find out. Le Yiran, known as an expert in investigating crimes, was recommended by the prince as a special adviser to the Wulin Department with her outstanding medical skills and reasoning abilities. Here, she met the man slandered by history books - Song Yuanchao.
However, the real Yuan Chao in Song Dynasty is very different from the historical records. The commander of the Martial Arts Division, who is only 25 years old, looks as gentle as jade on the surface, but is actually unfathomable. The Heluo swordsmanship he created implies the principles of heaven and earth, his chess, calligraphy and painting skills are superb, and his martial arts skills are unparalleled in the world. But under such a perfect appearance, there is a shocking secret...
When a series of bizarre martial arts murder cases occurred one after another, when undercurrents surged in the court, and when the mysterious Jianghu organization was ready to take action, Le Yiran discovered that what she had to face was far more than just a hero who had been misunderstood by history...
A huge conspiracy related to the fate of the country is unfolding, and the fates of her and Song Yuanchao are gradually entangled in the process of solving layers of mysteries. What kind of truth is it that makes an unparalleled hero willing to bear eternal infamy? How is her rebirth related to this dusty history?
Intention: This situation is complete and cannot be solved except by you.
