In the Dajing Dynasty, a storm is about to come.
Seventeen years ago, Shen Jinghong, a generation of swordsman "Duan Tide", was framed and sealed in a blood coffin. His whereabouts have been a mystery ever since. Seventeen years later, the "Blood Coffin Order" that had been lost for hundreds of years reappeared, and seventeen coffins were dug out - in the last coffin sat a living young man.
His name is Shen Yan, the son of Shen Jinghong, and he has been sleeping in a coffin for seventeen years.
The half-cut sword "Broken Tide" in his arms is the only relic left by his father, and it is also the key to unlocking all the truth. As soon as he came out of the coffin, he frightened Qishalou with the power of his sword and embarked on the road of seeking revenge.
However, the road to revenge is far more dangerous than imagined:
- The mysterious "Tingchao Pavilion" woman claims to know that his mother is still alive;
- The warning carved on the bottom of the coffin made him suspicious of Tingchao Pavilion;
- My father's death that year involved a huge dark web between the court and the world...
Is the mother alive or dead? Is Tingchao Pavilion an enemy or a friend? Whose hand was the carving on the bottom of the coffin? What is the truth behind my father's death? Holding a broken sword, Shen Yan entered the rivers and lakes and gradually uncovered the shocking secret that had been sealed for seventeen years. Every step is a trap, everyone is suspicious, and the half-broken sword in his hand will eventually set off a huge wave.
