She is a descendant of the Qimen of the Yu family and the leader of the Yu family's army. She is proficient in the secret arts of the Qi family, medical skills, and martial arts. She is now 19 years old!
Because of her outstanding strength, she was plotted by the treacherous ministers of the Yan Kingdom and betrayed the information to the Yao Kingdom. She was besieged by Yao Kingdom's killers on the battlefield and died from thousands of arrows piercing her heart. Although she died, her soul was still there, and she once traveled to the daughter of the enemy's left prime minister.
By accident, she was named the eldest princess of the Yao Kingdom, and married into the royal family of the Yan Kingdom on behalf of the Yao Kingdom. It was just in line with Yu Xingran's wish to return to the Yan Kingdom. On the way back to the Yan Kingdom, she went through many twists and turns, and was intercepted and killed by gangsters. She almost died in a foreign land. Fortunately, Cheng Jin, the national master, helped each other along the way, supported and cooperated with each other, and a friend in need was a friend indeed, and they exchanged feelings for each other. Finally, they were able to return to the Yan Kingdom. What followed was a bloody battle. The final outcome remains to be seen as the story develops.
