During the Northern Song Dynasty, the powerful Prime Minister Long Yutao colluded with foreign enemies and framed Zhongliang in order to gain political power. The entire Yang family was massacred, but the youngest son Yang Ming was rescued by his father's old subordinates and sent to Fanjing Mountain to practice martial arts for eighteen years.
Eighteen years later, Yang Ming mastered swordsmanship and went down the mountain to find out the truth about the murder. On the way, he met Xiao Jinghan, a scholar holding a folding fan - they were both orphans of a destroyed family, and the two became brothers;
He also meets Su Rongrong, the second young lady of the Su family. She dislikes the boudoir and prefers swords, so she joins hands with Yang Ming to investigate the case.
The three people peeled off the cocoons and found that all the clues pointed directly to Prime Minister Long Yutao and the "Dulong Society", a powerful force in the world under his control. And Long Tingting, the daughter of the Dragon Mansion, got acquainted with Su Rongrong and caught a glimpse of her father's conspiracy, so she decided to put herself in danger to help.
This pursuit of revenge in the world gradually unfolds the chess game of seeking a country. Yang Ming not only needs to kill the enemy with his own hands, but also needs to prevent the mountains and rivers from overturning. At the beginning of the sword, grievances and family and country are intertwined, and a bloody storm sweeping the government and the public has come.
