Zhu Erjue, the master of Yangzhou painting, hid in the cellar when the city was destroyed. Using his ears as eyes and blood as ink, he painted the tragic massacre of the city in seven volumes in seven days. On the eighth day, the Qing army arrived in pursuit, and he learned that there was another secret behind the massacre - hundreds of thousands of lives were stained with blood in Yangzhou in search of things left behind by the previous dynasty. Carrying the "Picture of Plum Blossoms" that his mentor protected with his life, Zhu Erjue stepped into the Plum Blossom Academy that had become a ghostland, and in the bloody puzzle stained with cinnabar, he uncovered a truth more cruel than death. The brush is the blade, and the painting is the witness. He wants to leave the final testimony for the silent Yangzhou.
