In the 23rd century, Su Qingwan, the heir to the ancient martial arts family and master of ghost medicine, traveled through time and became the legitimate daughter of the "evil star" of the Hou Mansion who had been abandoned for ten years. With a marriage proposal, she was forced to marry Xiao Juechongxi, the god of war, Prince Jing, who was disabled in both legs and was not going to die soon.
On the wedding night, the handsome prince in a wheelchair was dying. Su Qingwan raised her eyebrows after checking her pulse: "It can be cured, but it hurts." Xiao Jue raised his eyes: "You are not afraid of death, but you are still afraid of pain?"
From then on, the crippled king was succeeded by a little princess who forced him to drink bitter medicine and take silver needles every day. During the day, she disguised herself and opened the "Rejuvenation Hall", selling magic medicine, saving the emperor's life, training elite soldiers, and holding the economic lifeline of Dayong; at night, she used the spiritual spring to detoxify him and prolong his life. Wherever the silver needle passed, dead trees bloomed.
While the Hou family was waiting to see her become a widow, Su Qingwan was as rich as anyone in the country. When the enemy invaded and there was no one in the court, King Jing in the wheelchair was wearing armor again, and beside him, the princess in red wore a silver needle to determine life and death, and her long sword defeated thousands of troops.
Later, the world learned that it was the princess who cured Prince Jing's leg, that the emperor's life was saved by the princess, and that the enemy army was brought down by the princess with poison. The people who once laughed at her for marrying the crippled king are now on their knees begging her for a pill.
Xiao Jue held her in his arms and chuckled: "What else do you want to do, princess?" Su Qingwan counted the banknotes and raised her eyes: "The trade routes in the Western Regions have not been opened yet, and the pearl mines in the East China Sea have not been dug yet."
