This is an era when the weak are content and the strong are tyrannical.
This is still an era when all countries are secretly engaged in espionage wars.
Twenty years ago, the Rouran Kingdom was defeated by the Zhou Dynasty, a powerful country in the Central Plains. It was defeated like a mountain. The imperial capital was massacred, the main branches of the imperial line were cut off, and the whole country became a vassal state of the Zhou Dynasty.
Kutu Shijia is an outstanding killer in the "Silver Clothes Camp" where killers are hatched in the Rouran Kingdom. In order to avenge his brother, he transformed into Xun Chang, a prince of the Zhou Dynasty, and lurked in Shangjing for many years.
Xun Chang (Qutu Shijia) is getting older and his marriage cannot be postponed. When he goes to Qinjiang to track down the real murderer of Xun Chang, he meets Yin Yin, who has abandoned her aristocratic status, escaped from her oppressive family, and gone north to find her husband.
At that time, Yin Yin pretended to be the most beautiful Taoist nun in the world, and she and Xun Chang fell into the lair of Qinjiang water bandits. Yin Yin recognized Xun Chang's identity as a noble man in Beijing, but she chose to conceal her identity and helped Xun Chang capture Xu Liujiang, the leader of the water bandits.
After that, the two reached an agreement to be a pair of fake phoenixes - Xun Chang provided Yin Yin with a well-off life, while Yin Yin helped him take care of Jingyang's house and at the same time inquired about the news of the aristocratic family in Shangjing.
In order to dispel the suspicion of the two people's "marriage" by all the forces in Beijing, a four-year-old orphan was found and recognized as his "blood and flesh", and a thrilling and troubled journey of finding love and redemption began.
In this makeshift family, one is an enemy spy, the other is a daughter of a wealthy family who fled home, and the other is a sick and orphan child whose identity is a mystery. They hide each other's true side. They face many tests and have to work together to overcome one difficulty after another and create one miracle after another...
Purpose: There is only one kind of heroism in the world, which is to still love life after having tasted the ups and downs of life.
