In the evening, Xia Yu and his group were covered in dust and rushed back to the camp.

As soon as he entered the camp gate, Xia Yu hugged Li Daoxuan and said, "Prince Prince, I have worked hard all the way, go back early to rest."

"Pei Xuan, Du Qiu."

"military adviser."

"You two will go back too."

"promise."

After the arrangement was completed, Xia Yu hurriedly left.

This is something wrong!

Li Daoxuan was quite clever and raised his hand to call his personal soldiers over: "Follow the military advisor and see what you are doing. Be smart!"

"No." The personal soldiers went there quickly.

Pei Xuan and Du Qiu looked dark: Prince of the County, can you send someone to follow our boss? It’s hard for us to do it!

Li Daoxuan then remembered that there were two people next to him, and laughed dryly: "Well, aren't you afraid that the military advisor will be in trouble, and want to help."

I believe you! Pei and Du looked speechless.

"What are your expressions?" Li Daoxuan said with a embarrassed look and said, "I am a noble man in heaven, can I still be a small person?"

He just simply saw if there was a war.

Pei and Du looked at each other, why did Li Daoxuan beat Xiao Jiujiu? How could they not know? He shook his head helplessly and quickly escaped.

They are nobles, so it’s nothing to make a taboo, so they don’t dare to interfere.

Xuanjia soldiers stationed.

Xia Yu hurriedly arrived and found Qin Qiong's camp tent. Outside the tent, two personal soldiers were guarding him. When he saw Xia Yu, he hurriedly greeted him: "I have met the military advisor."

"Can General Qin be there?"

"General Cheng is here too."

Xia Yu lifted the curtain and saw Qin Qiong and Cheng Yaojin gathered in the corner of the tent, and were whispering something

"Military Advisor." Seeing Xia Yu come in, the two of them quickly got up.

"No need to be polite." Xia Yu sat down and said directly: "General Qin, do you think there is a detailed work of Zheng Jun in the camp, but is there any evidence?"

"There is no conclusive evidence, just suspicion."

"That day when he fought against Yang Gongqing, this person leaked his mouth and seemed very familiar with the military advisor. But the military advisors arrived, how do they know?"

"After coming back, I felt uneasy. I wanted to report to the King of Qin, but I was afraid that I would be suspicious and cause disagreement in the army."

"So, after thinking about it, I looked for Yao Jin to discuss it."

"Yi Jin thought that the military advisor was resourceful or had an idea. So, I dare not neglect and quickly compile a book and send it to you."

Qin Qiong is an honest man, and now he usually speaks clearly about pouring beans from bamboo tubes.

After hearing this, Xia Yu gently tapped the desk with his fingers and said slowly: "General Qin's worries are not unreasonable. I also think there must be a gap in the Tang camp."

"That day, I briefly interrogated Zhu Can, and this person is indeed very familiar with me."

"And he also revealed an important message that someone in Zheng's army was responsible for using the room, which was Wang Shichong's chief adviser Huan Fasi."

"This person is sinister and cunning, known as a poisonous man, and it is not surprising that there are hidden secrets in my camp."

Qin Qiong was excited when he heard this: "It's great. It turns out that the military advisor also feels the same. He is also worried that he is thinking too much."

"But, if there is really a little detail, you should remove it as soon as possible, otherwise there will be endless troubles."

"Yes, military advisor," Cheng Yaojin also worried, "If our army's movements are discovered by the Zheng army, it would be very disadvantageous."

"But there is no trace now." Xia Yu had a headache: "Who do you two think is the most suspicious?"

Qin Qiong and the other two looked at each other, but they did not dare to answer.

This question is deadly. It would be fine if you guess correctly. If you guess wrongly, you might kill the innocent, or you might be able to get a strong enemy out of thin air.

"Forget it, it's hard to answer, right?" Xia Yu sighed, closed her eyes and pondered, and then tapped the tabletop with his fingers.

At this moment, his mind began to search wildly.

In order to write a good graduation thesis, he consulted millions of words of historical materials, and there may be valuable clues among them.

However, the historical materials of how both sides use troops are very detailed, while spy wars are used in few words.

Of course, this is not surprising.

Is spy war? It happened in the darkness, and the dark activities involved are endless, and these are not suitable for recording.

Suddenly, Xia Yu's eyes lit up and he remembered something.

During the Eastern Expedition, Yuchi Gong was arrested by Li Yuanji. The charge seemed to be a crime of espionage, and he was almost killed.

However, Li Shimin firmly believed that Yuchi Gong was loyal and brave, and he stood up to everyone's opinion, so he released him and waited for him as usual.

So, what was the fuse for Yuchi Gong's arrest?

It's a search for a face!

Xia Yu's closed eyes suddenly opened, and his eyes flashed: Yes, during the Battle of the Eastern Expedition, Xunxiang suddenly rebelled against Tang and defected to Wang Shichong!

Xunxiang and Yuchi Gong were both surrendered generals of Liu Wuzhou, and even had a good personal relationship, which led to Yuchi Gong being almost killed unjustly.

Found you!

Xia Yu smiled, smiling proudly. There was no way, and she was awesome with golden fingers. She found the real owner from clues.

More importantly, he clearly remembered that the defection of Xunxian did not seem to have caused much serious consequences.

Therefore, he ignored it even after all the historical materials.

Cheng Yaojin had a lot of chickens. When he saw Xia Yu laughing as if he had found ten thousand coins, he quickly tentatively said: "The military advisor is so happy, but he has an idea?"

"No," Xia Yu said confidently: "What kind of people in the same camp are the most unstable and most easily confused by outsiders?"

Qin Qiong and the other two looked at each other and were still thinking, but Xia Yu took the initiative to announce the answer: "It's a surrender!"

Qin Qiong: “…”

Cheng Yaojin: "..."

Both of them looked strange and embarrassed: Military advisor, we are also surrendering generals. Are you pointing at the monk and scolding the bald man?

Seeing that the two of them looked wrong, Xia Yu also reacted.

"Sorry! Sorry!" The guy smiled dryly: "I'm not talking about the two generals. In fact, there should be a condition, that is, surrendering the general, but he is unsatisfied."

Qin Qiong and the others breathed a sigh of relief. It was true that they surrendered to the generals, but they were still highly valued in Tangying.

This is a busy job, but I put myself in it. That is not a true sucker!

"If that's the case," Cheng Yaojin touched his chin with interest: "The range is much smaller. Although there are surrendered generals of the Great Sui Dynasty, surrendered generals of the Rebel Army, Xue Ju, Liu Wuzhou, etc. in our camp, those who are not satisfied are those people."

"Tell me," Xia Yu was excited.

Although Xunxian was taken from historical materials, the records were too vague, and no one knew what kind of fellow scholars Xunxian had.

Even if he is looking for a face, he has no evidence. He can't say that he is a time traveler.

So, he needs more clues.

"The first one is to find the face."

"This person was originally under Liu Wuzhou's command, second only to Song Jingang and Yuchi Gong. After surrendering, he was still depressed and unsuccessful."

"Your Highness of Qin feels that this person is a bit too slippery at both ends, so he doesn't like it very much."

"At present, he served as a side general in the rear army and commanded two thousand troops, which is far inferior to Yuchi Laohei's pride."

"So, in private, I heard that this person has some complaints."

Xia Yu laughed when she heard this: Two people proved it, but the search for it didn't run away. She asked again: "Is there anyone else who is suspicious?"

"Long live that one."

"This person is also a general under Liu Wuzhou. He and Yuchi Laohei surrendered to Tang together. This person is cruel and bloodthirsty and is profit-oriented. His Highness the King of Qin is not too fond of him."

"At present, he is also a side general in the rear army, commanding two thousand troops, and he is very unsatisfied."

Xia Yu's heart moved.

Although he was not sure whether this Zhang Wansui was a mere fact, if he was looking for a picture, he would not miss such a natural ally.

“Is there any more?”

Cheng Yaojin scratched his head: "Xue Ju surrendered to the general Ma Jun, a prominent family in the northwest Ma family. He surrendered to the Tang Dynasty with Lao Zhai, and he was unable to do anything. He only had a side general under Lao Luo, the former army, and unified a thousand light cavalry."

"Others-" Cheng Yaojin wanted to say something else, but Qin Qiong gave him a wink, and the guy immediately woke up: "Uh, it seems that there are only a few people."

Qin Qiong's eyes, how could Xia Yu not see it?

He also understands what it means.
