On a rainy night, the body of a craftsman suddenly appeared in front of the Su family's old kiln, holding a strange piece of broken ice-cracked porcelain in his hand.
This is the third "accident" in the past three years, and rumors have arisen again: the Su family's porcelain is stained with the grudges of the previous dynasty, and could cost lives.
Seventeen-year-old Su Qingci looks timid, but picks up the key pieces of porcelain in the dark. She discovered that the cracks were going in the wrong direction—someone had poisoned the glaze.
At the same time, Shen Yanci, an appraiser who returned from studying abroad, suddenly visited. On the surface, he was appraising porcelain, but in fact, he was tracing the mysterious death of his father twenty years ago. Two unrelated murder clues point to the secret ice crack recipe that the Su family has guarded for hundreds of years, and a shocking secret about the "Pisces Playing Lotus Vase" from the official kiln of the Northern Song Dynasty.
The kiln fire was rekindled, revealing not only the porcelain, but also the ghosts in people's hearts. When her grandfather died suddenly, her cousin "committed suicide", and the porcelain workshop was bombed, and all her close relatives and support collapsed one after another, Su Qingci finally grasped the blood-stained seal of the family head.
This time, she wanted to burn not only the porcelain, but also the blood debt of twenty years, and build a clean Su family from the ruins.
