After the fall of the Southern Chu Dynasty, the eldest princess Shen Shuning and her younger brother stayed dormant in Shuodu, using ancient books to restore the secrets of restoring the country. They used Chu's acupuncture needles to preserve the lives of their loved ones, save their lives, and relieve the enemies' stubborn diseases. She and Lu Jinghan, the prince of Beishuo, the mastermind of the destruction of Chu, were pulled in the abyss of hatred between the country and the family. Their tit-for-tat relationship was deeply rooted in love, but they could not escape the fateful entanglement of "love and hate". In order to protect her young brother and restore her homeland, Shu Ning used her blood as a guide and her life as an injection to plot a plan on the edge of a knife; Lu Jinghan hid his deep love in the city, and in order to protect his sweetheart's sister and brother, he eventually died in a conspiracy in the court. When the blood-burning needle technique exhausted Shu Ning's last vitality, and when the palace was shocked, the farewell of life and death was frozen. Ten years later, Chu Ting returned to glory, and the mountains and rivers were intact. Only two lonely graves facing each other were left, engraved with lovesickness and regret that spanned the country.
