Datang: The prince of salted fish was overheard by Li Er

The man was looking around at this moment, trying to avoid everyone's gaze, but he still met Li You's eyes while his eyes were moving.

Feeling the scorching heat in Li You's eyes, the man was shocked again.

Accompanied by surprise, Li You's voice rang in his ears like a thunderclap: "Yinan Khan, what do you think of this case?"

Now Li You's target is the former Xue Yantuo's Pearl Khan Yinan.

This Pearl Khan Yinan came into view after Li You, Liu Bowen and others expanded their investigation personnel that day.

If the war between Datang and Gaochang really started, Xue Yantuo would have the greatest impact.

Geographically speaking, Xue Yantuo and Gao Chang can restrain each other and fight against the enemy together.

Therefore, Xue Yantuo's Pearl Khan Yinan wants to create chaos and rebuild the country, so he must cherish this opportunity.

It doesn't need Tang Dynasty to really lose to Gaochang. It only needs the battle between Datang and Gaochang to reach a stalemate, and Yinan Khan can take the opportunity to gather the old troops and re-establish Yating.

Historically, Xue Yantuo existed in the form of the Xueyantuo Khanate after his surrender. When the Tang army attacked Gaochang, they really attacked Datang.

If Li Shimin hadn't sent Ashna Simo in advance to take the Turkic people scattered in Hebei back to the grasslands and rebuild the tooth tent in Dingxiang, thus slowing down their attack speed.

Perhaps Xue Yantuo's attack would pose a considerable threat to Datang.

But this time, with Li You's preventive economic control, the possibility of Yi Nan wanting to restore the country has become less and less.

Yi Nan felt that if the current situation was allowed to continue, within ten years, he would be in a situation where he would have no money to use.

He needs to restore the country quickly in a short time. Even if he cannot restore the country, he must find a way to delay the use of Datang coins in Xue Yantuo.

Speaking of which, Xue Yantuo is the one who is making the slowest progress in the promotion of Datang coins outside the customs.

After Li You left the household department, he naturally transferred Hexi Wei back to Hexi.

Therefore, the promotion of Datang coins will be completely handed over to the market.

Although Datang coins have various advantages such as convenient portability, high security, and convenient transactions, the process of market change is still slow.

It can be said that if Kang Jie and his clan had not insisted on using Datang coins, this process would have become slower.

After careful analysis, Yi Nan's doubts became more and more serious.

Soon, Yuhuatian raised one of the biggest doubts.That was this time, Yi Nan Khan could not have appeared in Chang'an originally, but he found various excuses to stay in Chang'an, the biggest possibility was that he had a guilty conscience and wanted to know the situation as soon as possible.

For this reason, they made a scene in front of Yi Nan.

After screening out the suspicious person from Kang Jie's caravan, they invited the so-called wine man away in front of him.

Sure enough, the Turkic man who was in Kang Jie's team couldn't help sending out a letter soon.

But it's a pity that Li You's people made some mistakes when they were excited. They intercepted the letter, but failed to catch the person who received it.

And the lurking person was also stubborn, knowing that he was exposed, he killed himself on the spot, and did not leave any key evidence for Li You's people.

But even so, Yinan Khan spent the past two days in fear and anxiety.

For this reason, he almost didn't escape from Chang'an directly, but in the end he stayed behind in a strange way.

It has to be said that the move he stayed behind also bought him some time.

If he dared to escape, he would be captured by Jin Yiwei immediately.

Jin Yiwei is not like the joint trial of the three divisions. After confirming that Yi Nan is the mastermind, he will be arrested and interrogated first.

But just now in the Tang Dynasty, Yi Nan Khan showed a completely different performance from Kang Yandian and others, but it confirmed his identity.

Suddenly asked by Li You, Yi Nan was also shocked, and then he pretended to be calm and said: "Well, King Yan, I have no objection!"

"This Kangjie tribe has a bad reputation in the grasslands and often buys and sells by force. Even if there is no suspicion of collaborating with the enemy, it still needs to be rectified!"

Hearing this, Yi Nan was still pouring dirty water hard, and Li You was also amused for a while.

He said with a smile: "The caravan led by Kang Jie is promoting Datang coins. Is this called forced buying and selling?"

"They are also fair trades with clear prices. Compared with those merchants who are short of gold and poor in gold quality, I don't know how many times better."

Yi Nan became anxious, and quickly said: "They just use paper, what's the use of holding it!"

"Many tribes would rather collect less gold than return the paper!"

"Besides, the grassland people are simple and simple, and it is easy to be deceived when receiving paper!"

Although Yi Nan tried his best to explain, but after some explanations, the ministers who know the goods in the court also saw the importance of the promotion of Datang coins.

Li You chuckled and said, "The promotion of Datang coins is a national policy set by the Ministry of Households..."

The reaction of the ministers made Yi Nan even more anxious. He had already started to speak indiscriminately: "What kind of national policy is it, you made it up."

"You will come out and frame me for selling the military formation map and the number of troops to Gaochang, just to help your subordinates."

"I want Kang Jie to continue making money for you!"

"Everyone, my lord, Yi Nan is really not lying!"

However, this time, after Yi Nan Khan finished speaking, he found that the ministers above the court looked at him with strange expressions.

He opened his mouth and wanted to say something when Du Ruhui came out and said, "Khan Yi Nan, you are in a hurry."

Du Ruhui turned to look at Liu Dewei and the others and asked, "Master Liu, did we mention the number of troops when we reported the case this time?"

Liu Dewei shook his head and said: "Never, we just said that we suspect that someone has leaked the deployment position of our army."

Then Wei Zheng and Li Daozong also opened their mouths and said that they never said any redundant information.

Then Du Ruhui turned around and asked, "Yi Nan Khan, how do you explain this?"

Yi Nan Khan knew that Li You had led him astray from the Datang coin matter, and accidentally told the truth. At this time, he could only smash the pot and fall.

"Du Xiang, this is my guess."

"Think about it, since it is to assist Gao Chang in dealing with Datang's attack, it is natural to tell him the defense and the number of troops."

"I, a barbarian, was also half my life as a soldier, so I still have the common sense that I should have."

However, Hou Junji, the trusted minister of the Ministry of War, sneered and said, "I don't think so, so why don't you tell the other party that my Tang Dynasty has also mobilized [-] Xue Yantuo cavalry!"

"Before, I always suspected that there was fraud in this matter, but now it seems that everything makes sense."

After speaking, Hou Junji also took out a secret report.

Not only did Gaochang have spies in Datang, but Datang also had spies in Gaochang.

After the incident of the Kangjie tribe was exposed, the intelligence department under the Ministry of War began to operate rapidly.

Finally, a few days ago, a secret report from Gaochang came into the hands of Hou Junji, Shangshu of the Ministry of War.
