In the seventh year of the Apocalypse, the powerful officials of Dayin Dynasty were in power and the border was in crisis. The former Taishi Ling Su Wenyuan was destroyed because he uncovered Wei Zhongxian's secret conspiracy to collaborate with the enemy. The ten-year-old girl Su Qingwan was rescued by his loyal servant and escaped death with half a volume of "Jinglong Secret Records" which contained secrets on border defense. Ten years later, she changed her name to "Awan" and used her superb Su embroidery skills to sneak into the house of her enemy, Xie Chong'an, the chief minister of the cabinet, waiting for an opportunity to take revenge.
Xiao Jinghan, who was in charge of the execution of thousands of households in Dongchang, was the most powerful "minion" in front of the powerful eunuch Wei Zhongxian. He was cold and ruthless, and his hands were stained with the blood of Zhongliang. The two met for the first time because of an embroidery scandal. He saw that there was a vicissitude in her eyes that was inconsistent with her age. She suspected that he was the murderer who participated in the family's extermination. During the trial and error, they were forced to join forces because of the common enemy.
With the complete revelation of "Jinglong Secret Records", Su Qingwan was shocked to realize that her father's "collaboration with the enemy" was actually an unjust case, and Xiao Jinghan's true identity was that he was the son of a loyal general who died to protect the Su family - he lurked in Dongchang for revenge. Family feud intertwined with national hatred, love and righteousness collided. When Wei Zhongxian threatened Mongolia with a secret record and wanted to overthrow the country, the two faced the ultimate choice: should they join hands to avenge private revenge, or sacrifice to bring peace to the whole family and the country?
Old dreams are hidden in the light and shadow of swords, and loyal souls are embroidered on the tips of silver hairpins. They used their flesh and blood as pens to embroider a tragic legend of "putting country before family, and righteousness for everlasting life" in the ashes of history.
