"Zhang Xuan actually wanted to exchange Loufan County for Xiao Xian and his daughter. It's an incomprehensible weird idea!"

Li Yuan's eyes were full of mockery, "Does he think holding Xiao Xian will help him regain Nanjun?"

Li Yuan glanced at Liu Wenjing, who was also in the imperial study room, and asked, "What do you think of Liu Xiangguo?"

Liu Wenjing said respectfully: "Weichen thinks that Zhang Xuan may feel that betraying Xiao Xian is a loss of reputation, so he wants to use this method to restore his reputation."

Chen Shuda also nodded, "Weichen thinks so too."

Li Yuan snorted disdainfully and asked again: "What do you say about Lou Fanguan?"

"Your Majesty, I want to take it step by step, first take it back to Loufan County, and then talk to the other party about Loufan Pass. If the two are mixed together, they may not be able to get it back either."

Li Yuan walked back and forth in the study with his hands behind his back. In fact, he knew in his heart that with Loufan's important strategic position, Zhang Xuan would never give up Loufan Pass, but if he couldn't get Loufan Pass, they could not defend Loufan County. It was not a big deal to take back Loufan County, but it was not possible to realize it at the negotiating table. Only their army could capture Loufan Pass.

Li Yuan thought of Hetao again, and he felt upset. What he really cared about was Hetao. The Sui army captured Hetao, which meant that the Sui army's troops had pointed to Guanlong. No matter what, he could not let the Sui army capture Hetao, and the Sui army had to retreat.

Thinking of this, Li Yuan gritted his teeth and said, "You can answer Xiao Xian and his daughter in exchange for Loufan County. Don't bother with Loufan Pass anymore. Just talk to the other party about the Hetao issue and tell them openly that their invasion of Hetao is equivalent to tearing down the agreement signed before. I cannot guarantee that the five counties including Changsha, Yuanling and others will be handed over to them."

At this time, Liu Wenjing committed the problem of being unrestrained. He couldn't help but whisper: "How can Zhang Xuan spit it out after swallowing the fat meat in his stomach?"

Li Yuan glared at him and snorted heavily, "Those who have arrived in Chang'an cannot even think of returning to Zhongdu!"

The negotiations on the next day were almost in a stalemate. Wen Yanbo and Ling Jing insisted that they knew nothing about what happened in Hetao and could not respond to the Tang Dynasty's appeal.

However, Wen Yanbo and Ling Jing were shocked by the Tang Dynasty's preparation to break the contract and no longer deliver it to Changsha and other five counties. Although they also thought of this possibility on the way, they did not expect that the Tang Dynasty would really tear up the previous agreement.

In protest, Wen Yanbo and Ling Jing immediately withdrew from the negotiations and returned to the VIP hotel by carriage.

The carriage walked slowly on the Suzaku Avenue, with both sides guarding them safely, and the iron armored cavalry of the Tang army, holding long spears in their hands, surrounded the carriage so that it was blocked.

At this moment, a piece of paper suddenly rolled in from the corner of the car window. Wen Yanbo was stunned. He opened the piece of paper and saw a sentence written on it, "The emperor has decided to put the house arrest and the cavalry of the VIP hotel has been arrested and detained. If you have any news, please immediately."

Wen Yanbo was shocked and handed the note to Ling Jing. Ling Jing's face changed and he sneered: "It seems that all the negotiations before were made up. The key is Hetao. What Li Yuan wants is Hetao."

Wen Yanbo pondered for a moment and whispered: "Can it be the other party's trick that let us expose the Chang'an Intelligence Agency?"

Ling Jing thought for a while and said, "It doesn't feel very similar. The key is who is reminding us?"

This sentence is crucial, who is helping them?

Wen Yanbo pushed the car window open a crack, and a Tang army captain close to the car window whispered: "I am Yu Gong's man, please believe me."

Wen Yanbo was an official in the court. He didn't understand the meaning of this sentence, but Ling Jing knew the inside story. It must be Yu Yun who was secretly helping them.

He nodded and said to Wen Yanbo: "You can believe it!"

Ling Jing immediately wrote a note and handed it to the cavalry captain and said, "Leave this note to the Qingyun Restaurant's high tent!"

The Tang Army Captain quickly took the note and stuffed it into his sleeve. He gently urged the war horse to run forward.

The Tang Army Captain did not deceive them. The VIP hotel was surrounded by three thousand Tang army soldiers. When the Northern Sui envoys entered the gate, the gate was immediately closed, and a seal was posted, and Wen Yanbo and others were placed under house arrest in the VIP hotel.

Li Yuan was already determined. If Zhang Xuan did not withdraw from Hetao, he would never let him go. The various consensuses that had been reached before were kicked away by Li Yuan. He didn't care about any spoils, and it didn't matter if he couldn't get back Loufan County, but the Sui army would never be able to get Guanlong.

At noon, the young son Yu Weiming came to Qingyun Restaurant, which was a regular visitor here. Although Qingyun Restaurant is the Yu family's property, his father had handed over Qingyun Restaurant to the Chang'an Intelligence Agency to operate, so the Yu family no longer involved in the restaurant. However, the Chang'an Intelligence Agency is a bridge between Yu Yun and the Northern Sui Dynasty, so he would of course let his son come and go often.

Yu Weiming entered a elegant room on the second floor. After waiting for a while, Gao Jin also walked in quickly and said with a smile: "I'm still going to find my brother in the afternoon. What a coincidence, I didn't expect my brother to come to my house by myself."

"Brother, come to me if you have something to do?" Yu Weiming heard something in Gao Jin's words.

Gao Jin nodded, took out a letter from his arms and handed it to him, "This is the reply from His Highness the King of Qi to Lingzun, and it was only delivered last night."

Yu Weiming was overjoyed and quickly took the letter, looked at it and put it away carefully. He said, "I have something important to come to find my brother."

"What's the matter?"

"Brother, don't know yet! The VIP hotel has been blocked by three thousand troops, and all the Northern Sui envoys have been under house arrest in the hall."

Gao Jin was shocked and asked anxiously: "When did this happen?"

"Just happened just half an hour ago."

Yu Weiming took out another note and handed it to Gao Jin, "This is the note written by Ling Chanjun halfway back to the hall. Let us pass it over to his brother."

Gao Jin hurriedly took the note and opened it, and saw a sentence written on it, "The Hetao negotiations broke down, and the five counties including Changsha fought for a contract," which was Ling Jing's handwriting.

Gao Jin pondered for a while and asked, "How did you get this note?"

"The Yulin Army Captain who guarded the envoy was a general of the Yu family. After my father learned that the emperor ordered the envoy to be placed under house arrest, he immediately notified the envoy to pass the message. Ling Jing wrote this note on the way. If the brother wanted to contact them again, we might not be able to do it."

Yu Weiming understood what Gao Jin meant. Gao Jin wanted to borrow their power to contact Wen and Ling, but they were really powerless.

Gao Jin had no choice but to nod, "I understand, I will send away Ling Guanjun's notes immediately."

Yu Weiming was anxious to send Zhang Xuan's handwritten letter to his father, but he didn't care about eating and stood up and said goodbye. Gao Jin immediately went to Dongcheng City and arranged for the Yingxin to send it to Loufan County. They could not contact Hetao directly, so they could only send the Yingxin to Jingle County, Loufan County, and then forwarded it to Hetao by Fang Xuanling.

The Yu family is in Kaimingfang next to Wubenfang. Yu Weiming left Qingyun Restaurant and soon returned home. His father, Yu Yun, who served as the craftsman, happened to have lunch break at home. Yu Weiming hurried into the study and knelt down to salute his father.

"Have you given that note to Gao Jin?"

"Report to my father, I have already given it, and he said he would send it away immediately."

Yu Yun nodded. Today was indeed a bit abnormal. The emperor actually issued an order to put a house arrest for the Northern Sui envoy. This was the first time the Tang Dynasty was established. The emperor was so furious and lost his composure.

Of course, Yu Yun was not surprised. He also knew that Hetao was captured by the Northern Sui Dynasty. This incident was indeed very serious. Once the Northern Sui Dynasty destroyed Liang Shidu to the west, the gates between Longyou and Hexi would be opened to the Sui army. On the contrary, if the Sui army destroyed Song Jingang to the east, the army would reach Shangjun directly, and it would be close to Guanzhong. This is a series of serious consequences caused by throwing away the three counties of Bingbei. The three counties of Bingbei are like a corridor. If the corridor is occupied, the road to the west will be presented to the Sui army. No wonder the emperor was furious and did not even want the most basic etiquette.

At this time, Yu Weiming took out the letter in his arms and presented it to his father, "This is the reply from His Highness the King of Qi to his father. It was just delivered to me last night, and Gao Jin gave it to me just now."

Yu Yun was very happy and hurriedly took the letter. He opened it and read it quickly. Zhang Xuan's words in the letter were very tactful. He praised his efforts to unify the world, and at the same time he placed hope for the future of the family. Seeing this, Yu Yun was very excited. The letter had already made it clear that the future of the Yu family would be guaranteed. At the same time, he admired Zhang Xuan's ability to speak and said that betrayal of the Tang Dynasty was made for the unification of the world, which made Yu Yun morally gain a foothold.

Yu Yun continued to read again. After the letter, Zhang Xuan put forward several more requests, such as asking him to continue to support the Chang'an Intelligence Agency and let him continue to keep a low profile and concealment.

Finally, there is another one. Zhang Xuan said it very implicitly and tactfully, but Yu Yun still understood it. Zhang Xuan asked him to unite such as the Dugu family and the Yuan family to jointly create a new situation for the Guanlong family. (To be continued.)
