Yun Shu, the legitimate daughter of the Hou Mansion, mistakenly believed Prince Ye Chen and his concubine Yun Yao in her previous life, and they jointly framed her for treason and the death of her brother. She was deprived of Canghai's bloodline and secret treasures. In the end, her whole family was executed, and her soul was destroyed in Canghai Secret Realm. When she was crying and cursed with blood, she was unexpectedly reborn and returned to the eve of her sixteenth birthday. At that time, her relatives were still alive, the prince's mansion was safe, and the conspiracy had not yet begun.
With the blood feud and prophetic memory from his previous life, Yun Shu lost her innocence and took up the sword and swore to protect her relatives and collect blood debts. She picked up the "Xuan Shui Jue" that she had abandoned, practiced the secret technique of Canghai bloodline, honed her skills in the martial arts field, and worked step by step in the whirlpool of power and intrigue. During the royal hunt, she avoided the trap of "love at first sight" with Ye Chen and returned all Yunyao's plots, exposing his ugly face; above the court, she understood Ye Chen's conspiracy to seize the legitimate son, and secretly planned to dismantle the foundation of his power; the fog of the Canghai secret realm gradually cleared, and she took the initiative to explore the truth about the secret treasure, control the power of her blood, and get rid of the fate of a chess piece.
On the way to revenge, Yun Shu encounters Xiao Ce, a young general who was buried in his previous life. The two have formed a deep bond from testing each other to fighting side by side. Faced with her stepmother's ruthless schemes, the turbulent events in the court, and the test of life and death in the secret realm, she uses her wits to overcome the situation, protects her weaknesses with a sharp edge, and sticks to her true heart amidst the entanglement of love and hate.
When the true secret of Tears of the Canghai comes to light and the shackles of fate are approaching again, can Yun Shu, who has undergone rebirth and transformation, completely reverse the situation, protect the people he loves, and make Ye Chen, Yunyao and all other enemies pay for their debts with blood? This counterattack that spans life and death will eventually stir up a storm in the world.
