While the border soldiers were training intensively, the lively atmosphere in the Five Cities was still there. All the martial artists had not left. They were all waiting to catch a glimpse of the new leader and to exchange ideas with him.

The emperor rested in the house for five days, and the swelling on his face finally subsided, but there were still bruises on his face. Fortunately, the medicine prescribed by Imperial Doctor Miao was very effective, and he also practiced qigong every day to regulate his body. On the tenth day, his face finally recovered as before, and he had the face to go outside to bask in the sun.

The ministers offered auspicious words one after another, but only Kan Chaoyan brought news: "Your Majesty, we have interrogated the identities of the spies who participated in the Wu Zun competition. They are spies sent by Jiu Guang, Jiu Yue, Jiu Ao, Jiu Sheng, and Jiu Yu. Each of them has the strength of a Wu Zun. They participated in the competition to gain the position of leader and the support of the martial arts community, and then instigate everyone to rebel together. But the most terrifying thing is that they sneaked into Da Qian as spies seven years ago."

"Seven years ago?" The emperor was shocked. She had sneaked in as a spy before he unified the five kingdoms. "Did the spy say that?"

"Yes, we used hallucinogenic powder on them to make them hallucinate and force them to tell the truth." Kan Chaoyan frowned slightly: "Of course, the hallucinogenic powder may not really work on Wu Zun. It is possible that some lies are mixed in, but I think that 70% of what they said is true."

"Then what are their identities in Daqian Country..."

"They are all gang leaders, and the governor has already led people to raid their branch offices. I believe good news will be reported back in an hour."

The emperor was really worried: "Can you find out if they have any accomplices? For example, is it possible that their people are serving in the court?"

Kan Chaoyan shook his head: "We asked about this matter, and they all said that they received the spy mission through letters. Even if there are accomplices who have sneaked into Daqian Kingdom, they don't know who the other party is, let alone what they do."

"If the spy is just a civil servant, it won't cause any big trouble. But if he is a military officer, or a military officer in a frontier area..."

Even before the emperor finished speaking, Kan Chaoyan knew the seriousness of the matter: "Your Majesty, don't worry. We only need to ask one person to find out if there are any spies on the border."

He glanced across the courtyard, and the emperor immediately understood.

The person who lived opposite the emperor's courtyard was Mu Nanjin. As long as she was there, there was nothing they didn't know.

When the emperor thought of Mu Nanjin, he felt a mixture of love and hate. How could there be such an annoying little girl in this world?

He sighed: "She is really suitable for the position of Jinyiwei."

Kan Chaoyan agreed: "She is still suitable to stay in the Ministry of Justice. With her around, there is no case that cannot be solved."

The emperor nodded and said, "When we return to the capital, let the governor find a reason to have her stay in the Ministry of Justice for a few days. Once all the old cases are dealt with, she will have done a good deed and will have done a great deed."

"Huff—"

Suddenly, the sound of Mu Nanjin sneezing was heard from the opposite yard.

[Who is scolding me? Or who is thinking about me? ]

The emperor and Kan Chaoyan shut up immediately.

The emperor raised his chin towards the courtyard opposite, signaling Kan Chaoyan to go to Mu Nanjin to do the work.

Kan Chaoyan came to Mu Nanjin's yard with a smile on his face: "Mu girl, don't you have to go on duty today?"

"I have to go out for some errands today."

Mu Nanjin sat on the rocking chair and rocked.

Kan Chaoyan asked with great concern: "Are you going out to do something? Do you need my help?"

Mu Nanjin glanced at him and said, "Aren't you busy investigating the spy? How do you have time to help me?"

"It gives me a headache just talking about this matter." Kan Chaoyan sighed deliberately and sat on a stone bench nearby: "Don't you know that the mouths of these five spies are like they are sewn together and can't be pried open no matter how hard you try? They would rather die than reveal who their accomplices are."

He rubbed his temple and said, "The emperor has only given us one day to interrogate you. If we can't get the answer, we will be punished."

Mu Nanjin asked casually, "What's the punishment?"

"At the lightest, it will be a fine of half a year's salary for our left court. If the fine is heavy, it's hard to say."

He originally wanted to say demote him, but changed his words when he realized that demote him was exactly what Mu Nanjin wanted.

[Half a year's salary is only a few dozen taels of silver. I have money now, so I don't care about these few dozen taels of silver. If you want to fine me, then fine me. Hehe.]

Kan Chaoyan: “…”

Now that the little girl has grown up, she doesn’t even care about a few dozen taels of silver.

"But if someone can do this well, then the person who does it well will be rewarded with a thousand taels of gold."

"A thousand taels of gold?"

Mu Nanjin's eyes lit up slightly.

[Ask a few questions and you will get a thousand taels of gold, which will be enough for Taotie's food for ten days. ]

Kan Chaoyan secretly breathed a sigh of relief. Fortunately, money was still attractive in Mu Nanjin's eyes, otherwise it would be difficult to ask her to do things again.

"Yes, I can't ask all the questions, and I don't have the blessing to get a thousand taels of gold."

If Mu Nanjin could reveal the other spies, the emperor would be willing to give her, not to mention a thousand taels of gold, even ten thousand taels of gold.

Mu Nanjin glanced at the sky and said, "It's still early. I'll go interrogate the spy first, and then do my work."

Kan Chaoyan asked in a fake tone, "Do you have a way to find out?"

"You'll know after you try it."

Mu Nanjin took Wu Yuan into the cell with the list of names obtained by Kan Chaoyan during the interrogation.

Kan Chaoyan was waiting outside, and she came out after just a quarter of an hour.

He was surprised and asked, "It came out so soon? Did they find out after the interrogation?"

"I found out what I asked." Mu Nanjin handed Wu Yuan the case file he had written and said, "When you return to the capital, remember to send the thousand taels of gold to my house."

After saying this, she took Wu Yuan away. She had to go buy materials with Chen Dao today, so there was no time to delay any longer.

Kan Chaoyan watched them leave in a daze. It took him ten days to figure out a task, but the other party did it in just half a minute. He had to admire them.

The five spies in the prison were even more confused.

Mu Nanjin came in and first read out their names, and then told them all the stories of their ancestors like telling a story. Moreover, she knew more about things they didn't know than they did. She could even accurately name the other spies in the Daqian Kingdom and knew what official positions their accomplices held.

Finally, they were forced to put their fingerprints on the case file.

Not only was there no torture or threats or inducements from beginning to end, but the results were also obtained at the fastest speed.

While they were still confused, the other party left with the case files.

The spy from the Nine Territories asked the spies from the other four nations, "Did she just say that what happened in your country was nonsense?"

In fact, you don’t need to ask, you can tell from their expressions that what Mu Nanjin said is true.

The spy from the Nine Saints said, "I think she is more of a spy than us. Moreover, she is an old spy who has been lurking in our country for a long time. She has seen through all our secrets."

The spy from Jiuguang Nation was puzzled: "By the way, if they knew everything about us, why did they torture us so severely before? And forced us to drink so many drugs?"

The spy from the September Kingdom snorted coldly: "I think they just want to beat us, but they are afraid that we are from a medium-sized country, so they have to find a reason to torture us."

The spy from Jiuao Country pooh-poohed, "The people of Daqian Country are just despicable."

The other four nations agreed: "Yes, despicable."

Kan Chaoyan, who was standing outside the cell and heard their conversation, said: "..."
