Xie Yu, the daughter of a loyal minister, was framed and involved in the rebellion of King Xun because her father was too upright in the court. His father committed suicide in prison after proving his innocence, and the Xie family was exiled because of this. On the way, when passing through Kangping County, Taiyuan Prefecture, Xie Yu was buried due to fake death, and was later rescued and adopted by a widower who went up the mountain to chop wood, and since then the woman has changed her name to Xie Yu in disguised as a man.

Xie Yu, who wanted to overturn the case for the Xie family, started from the arrest of the Kangping County Ya, because Kangping County made Fu Lin honest and independent, Fu Lin, who was isolated by a group of officials in Taiyuan Prefecture, had not been promoted for fifteen years, but Xie Yu knew that Fu Lin was a good official, and when the imperial court sent an inspection of Qincha, there were two murders in Kangping County, which had always been stable, and there were two murders one after another.

Xie Yu's loyalty was favored by Pei Heng, who intended to promote him and bring him into Beijing, and Xie Yu also took the first step in overturning the case for the Xie family in this opportunity.

With Pei Heng's inspection all the way, Xie Yu on the way to Zhengzhou Mansion, and broke the curse of the Longmen Grottoes, as the case was cracked, everyone also found the old armory hidden under the grottoes, because the weapon was engraved with the word Xun Wang and there were traces of use, resulting in the Xun Wang rebellion ten years ago was mentioned again.

Pei Heng, who was entrusted with an important task by the emperor, took over the case again to completely eliminate the possible rebellious ministers. In order to overturn the case for Xie Yu, who was full of people, followed Pei Heng around, investigated in various parts of the country, and in the process of investigating old things, Xie Yu, who had solved the case many times, gradually aroused Pei Heng's interest.

Knowing that the brothers and sisters who were exiled back then were still alive, Xie Yu encouraged Pei Heng to go to the place of exile to investigate, but Xie Yu, who was reunited with her family, was discovered by Pei Heng at this time. Xie Yu, who knew Pei Heng's character, thought that she was in a catastrophe at this time, but she never thought that Pei Heng would help her hide it, Xie Yu was moved, only to know that Pei Heng had a relationship with his own family, it turned out that Pei Heng had great respect for the upright Xie father when he was young, and because of his identity, he went to Xie's house under the alias Zhao Jing. Xie's father took him very seriously, but unexpectedly, Xie Yu's brother was dissatisfied, and he wanted to play tricks on Pei Heng, causing Pei Heng to be injured in Xie's house. And Xie Yu was loved by Xie's father and took the punishment for his brother. And after Pei Heng left the Xie family, he was worried that his injury would cause Xie's father to be implicated, so he never had contact with the Xie family again.

The Xie family was framed and involved in the case of King Xun's rebellion, and it was precisely because of Pei Heng that his father interceded for the Xie family in the court, in exchange for the Xie family's family being exiled.

Xie Yu also had feelings for Pei Heng day and night, and she looked forward to the day when the Xie family overturned the case, and she could be with Pei Heng in a dignified manner. At the same time, the case of the Xie family being implicated in the rebellion has also progressed, and the correspondence between the Xie family and King Xun was found again, Xie Yu recognized that the handwriting on it was indeed the pen of Xie's father, and he always thought that Xie Yu, who firmly believed that the Xie family had been wronged, was hit hard and could not believe that his father was really involved in the rebellion case.

After losing her faith, she gradually became depressed, and she didn't dare to reveal the feelings in her heart as the daughter of a guilty minister, and decided to part ways with Pei Heng.

Pei Heng, who was aware of Xie Yu's thoughts, had a showdown with Xie Yu, and showed him his discovery, proving that although Xie's father corresponded with King Xun back then, both of them were framed by traitors, and King Xun and others were also framed by others, and they did not have the intention of rebelling.

Xie Yu, who found out this, was greatly encouraged, and was determined to completely overturn the case for everyone who had rebelled against King Xun back then, but unexpectedly found that the person who framed King Xun for rebellion was His Majesty today, just to eradicate the dissidents.

The emperor knew that King Xun was innocent, and the armory under the Longmen Grottoes was also made to frame King Xun. The emperor, who had forgotten about the incident, was worried that someone was really rebelling after discovering that there were really traces of use in the armory, so he appointed Pei Heng to find out the traitors in the court who really had the intention of rebellion under the pretext of investigating the current affairs.

At the same time, there was an abnormal movement outside the pass, and Pei Heng and Xie Yu were captured outside the pass.

Xie Yu, who was living outside the gate, determined that there was someone in the court who collaborated with the enemy and treason, and Xie Yu finally found out the person who collaborated with the enemy, and this person was actually Pei Heng's father.

It turned out that the armory that framed King Xun ten years ago was created by Pei Heng's father by the emperor's order, and the idea of rebellion was born.

In distress, Xie Yu stepped forward to rescue Pei Heng. In the end, all the truth was revealed, and the Xie family was wronged.

Pei Heng and Xie Yu, who saw through the sinister court, finally resigned and went into hiding.

Finale.
