Su Wan, a survivor of the massacre of the Su family ten years ago, is striving for revenge at every step. On New Year's Eve, she sneaked into a gathering of Boss Wu, the old member of the Blood Sparrow League, and successfully subdued Boss Wu, the murderer of her mother. She learned from him that the man behind the scenes was actually Zhao Huan, the Minister of War at that time. Xiao Yan, an official from Dali Temple, arrived in time, put Wu Laoda on death row, and promised to investigate the case thoroughly. Su Wan felt confused after the support of revenge collapsed. During the Lantern Festival, Xiao Yan invited her to serve as a sacrifice in the medicine storehouse of Dali Temple. Faced with Xiao Yan's solemn words of "I don't believe in cause and effect, I only believe in knives and scales, and I believe in you even more", Su Wan let go of the past and accepted a new position, like a phoenix rising from nirvana, ushering in a new life in the lights of Chang'an.
Mission: Ten years of redress of injustice, one day of redress. On New Year's Eve, Su Wan cleverly captured the boss of the Left Guard of the Blood Sparrow Alliance, Fawu, and uncovered the truth behind the massacre of the Su family, pointing out the man behind it, Zhao Huan, the Minister of War. With the firm support of Xiao Yan, the young minister of Dali Temple, the sword of justice broke through the fog of power desire, and the iron law of the king finally brought the guilty officials to justice. When the obsession for revenge gradually dissipated, Su Wan took over a new life in the Lantern Festival lights. With her ability to identify medicines and poisons, she joined the Dali Temple and found inner peace and salvation behind the flash of swords. The story is intertwined with hatred and justice, machinations and tenderness. Finally, in the bright lights of the thousand-year-old ancient capital, it shows the strength and hope of those who have experienced disasters and are reborn.
