On the eve of the Yinqiong Kingdom Princess Yingran's banquet, envoys from the seven countries gathered. The leader of the Yunyin Kingdom's tribute gold team saw that his country's envoy Yu Han was taciturn and was inexplicably provoking and throwing punches. However, Yu Han backhand subdued him, and everyone was shocked to realize that the tall and tall envoy was actually a woman.
After entering the imperial city, the leader held a grudge and took advantage of Yuhan's physical weakness to knock her out and sell her into a brothel. Yuhan would rather die than obey, accidentally injuring a guest, and was abandoned in an alley next to the brothel. He happened to be rescued by Yingran on patrol at night. King Yinqiong saw that Yuhan was excellent in martial arts and appointed him as Yingran's personal bodyguard. After three years of morning and evening companionship, Yingran's trust and warmth became the only light in the cold and dark sky. The two were more than master and servant, and their friendship was deep and difficult to understand.
Unexpectedly, Yunyin Kingdom suddenly raised its troops, and the leader captured Yuhan's mother and forced her to treason. On one side was the grace of childbirth, and on the other was the love of meeting again, Yu Han finally chose the former - she burned the palace, pointed her sword at King Yin Qiong, and ended three years of peace with her own hands. Yingran witnessed her blood-stained appearance, and became a prisoner after the destruction of her home and country. However, Yuhan disappeared without a trace since then, and hatred has been entangled with her like poisonous ivy for five years.
One rainy night, while Ying Ran was sleeping in a pigsty, she was called by the God of Marriage in her dream and was given a magic formula. During the day, she worked as a lowly servant in Yunyin Kingdom, and at night she hid in the woodshed to practice secretly. After a few years, she finally ascended and entered the Yuncui Immortal City. However, when she stood under the immortal steps and saw the figure wearing black clothes with the same eyebrows, the blood in her body froze instantly - that person was Yuhan.
