The so-called "one move" is the overall situation. The Sui army unexpectedly occupied Shanggu County in November, which not only put huge pressure on Youzhou Luoyi, but also made other Hebei forces nervous. Among the four major forces in Hebei, Wei Daoer was the weakest, Gao Kaidao, the second was Youzhou Luoyi, and the most powerful was Dou Jiande.

Faced with the strong eastward expansion of the Sui army, all major forces in Hebei realized that it would be difficult to resist the Sui army with the power of one side alone. In this case, the call for abandoning past grudges and the call for joint resistance to the Sui army gradually appeared among the major forces. First of all, the alliance between Luo Yi and Gao Kaidao. They joined forces more than once in the battle against Dou Jiande to the north. This time, the Sui army expanded eastward, and Luo Yi and Gao Kaidao naturally reached an alliance agreement to jointly deal with the Sui army.

At this time, Dou Jiande also had the idea of ​​joining Luo Yi to fight against Sui. As early as a month ago, he sent Song Zhengben to Youzhou to contact Luo Yi secretly. Dou Jiande originally considered contacting Luo Yi many times to ease the hostility of both sides, and then proposed the joint proposal of both sides. Unexpectedly, the Sui army occupied Shanggu County in advance and disrupted Dou Jiande's plan, but at the same time it also brought opportunities to Dou Jiande.

As night fell, a carriage drove into Youzhou City. In the carriage, Song Zhengben stared at the streets shrouded in the night, but was thinking about the next direction of the Sui army.

Like Wen Yanbo, Song Zhengben also believed that the purpose of the Sui army's attack on Shanggu County was to open the door to attack Hebei, establish a granary and military-capital land, and lay the foundation for the Hebei battle next spring. If you consider this, it would be completely reasonable for the Sui army to attack Shanggu County now and it is not surprising.

This shows that the Sui army has not changed its plan, and they also need time to build warehouses and transport supplies. Youzhou is not Shanggu County. Once it enters a confrontation, if there is no sufficient supply of food and grass, it will be difficult for the Sui army to win this war in such a cold winter. This is not a surprise soldier to win.

So the time for the Sui army to launch the Hebei offensive should be next spring, which gave them two months. They can use this time to establish a temporary alliance to unite against the Sui army.

Song Zhengben is still very confident about his mission to this trip. When he secretly went to Youzhou last month, he saw that Luo Yi was already tempted, and now Luo Yi is facing huge pressure. As long as the strategy is right, the possibility of success will be even greater.

As for Gao Kaidao, Song Zhengben was not worried. As long as he convinced Luo Yi, Gao Kaidao would naturally become one of the alliances. By then, a powerful triangular alliance will be formed and he will no longer be afraid of the Sui army's eastward expansion.

At this time, the carriage began to slow down. "Master, we are here!" The voice of the coachman came from outside.

Song Zhengben looked over and saw Luo Yi sending Wen Yanbo out of the mansion. He seemed to be saying something. Song Zhengben immediately ordered the coachman, "Slow down!"

Song Zhengben knew that most of Luo Yi's subordinates hated Dou Jiande. Before he had negotiated with Luo Yi, he did not want to be seen by Luo Yi's subordinates to avoid unnecessary trouble.

Wen Yanbo got on the carriage and said to Luo Yi: "I will set off tomorrow morning and will definitely bring good news to the prince."

Luo Yi smiled slightly, "I wish Sima a good journey!"

The carriage started, gradually walked away, and disappeared into the darkness. Luo Yi was about to return home, but turned around and saw another carriage. The curtain of the carriage was opened, and he saw Song Zhengben with a smile on his face. Luo Yi was stunned for a moment.

In the study, Luo Yi and Song Zhengben sat down. Luo Yi did not expect that Song Zhengben would suddenly visit at this time. He had just discussed with Wen Yanbo the strategy of dealing with the expansion of the North and Sui Dynasty, and Song Zhengben appeared.

A maid served them tea. Then she stepped back. Song Zhengben picked up the tea bowl and smiled and said, "What's the statement I said last time with the general manager?"

Of course, Luo Yi knew what Song Zhengben was talking about. He was extremely moved by the alliance with Dou Jiande, but Wen Yanbo's persuasion made him a little shaken. He knew Dou Jiande very well. When he needed to use people, Dou Jiande could bend down and lower his head. But once you were not needed, he immediately turned his back. He just patted his shoulder and stabbed him with a knife. Luo Yi really didn't believe in Dou Jiande's sincerity.

He pondered for a moment and said, "I'll consider this matter again."

Song Zhengben's mouth twitched slightly. Now it was already burning, and Luo Yi actually had to consider it again. Song Zhengben immediately guessed Luo Yi's thoughts. I'm afraid Luo Yi had thought of something to deal with Yang Yuanqing, so he became less enthusiastic.

Song Zhengben couldn't help but sneer in his heart. With Dou Jiande's hundreds of thousands of troops, the forces that separatisted most of Hebei were not sure to confront the Sui army, and he had to find a way to fight against the Sui army. Luo Yi had only 50,000 troops and only had three small forces in the territory. Do he think he could compete independently with the Sui army?

Of course, Song Zhengben could not say this, as this would annoy Luo Yi. He advised tactfully: "We also know that the Youzhou army has strong combat effectiveness, and has the assistance and support of Gao Kaidao's 100,000 troops, and sufficient food. Such strength is indeed not to be underestimated. However, General Luo did not understand the strength of the Sui army. He attacked Fengzhou with hundreds of thousands of Turkic troops, and was defeated and returned home in a crushing defeat. Who can do this? Moreover, in the battle of Hanoi County, tens of thousands of elite old troops who had followed my lord for many years were wiped out. We deeply realized that we cannot fight against the Sui army by relying solely on our own. Only when the entire Hebei forces unite can we be able to match the Sui army."

Song Zhengben's earnest persuasion made Luo Yi a little moved. He originally wanted to join forces with Dou Jiande, but was temporarily persuaded to withdraw by Wen Yanbo. At this time, Song Zhengben showed the facts, and Luo Yi suddenly realized that he was a little naive and thought that he could fight against the Sui army with his own strength. The 300,000 Turkic army was defeated by Yang Yuanqing's powerful force, and can his tens of thousands of Youzhou army defeat the Sui army?

Song Zhengben saw that Luo Yi was already tempted, so he used his killer move and said slowly: "Master Luo, I am forgiving, we should not be the ones who are anxious now. Judging from the current Sui army's troops, the first one he wants to attack is obviously Youzhou, not us. I can completely watch the tiger fight. When the Sui army and the Youzhou army fight both sides, we will send troops to attack the Sui army. I believe that our army will drive the Sui army out of Hebei, but my lord did not do this. We are considering that our lips are dead and teeth are cold. If Youzhou is over, then it will be our turn next. Although our two families have always been in a state of disagreement, in the face of the common foreign enemies, we should abandon past grudges and unite against the Sui Dynasty. This is a wise approach."

Song Zhengben's words hit Luo Yi's key point. If the Sui army and Youzhou army really fought each other and suffered both losses, then Dou Jiande would have been the one who laughed to the end. He sent all his troops to drive the Sui army out of Hebei and then ate himself. Wouldn't it be easy?

Although Song Zhengben did not say it clearly, Luo Yi understood it and he felt creepy. No! You must not let Dou Jiande stare at him, and he must also pull him into the water and bear the price of fighting against the Sui army. In this way, he is unable to eat himself.

Thinking of this, Luo Yi finally made up his mind and nodded slowly, "Mr. Song said very well, his lips are gone, and the teeth are cold. Youzhou is over. The next one is your turn. Yang Yuanqing is our common enemy. Everyone should abandon the grudges of the past. Join hands to fight against the Sui Dynasty. Please tell King Changle that Luo Yi is willing to work with him to fight the Sui army eastward expansion."

"So General Gao Kaidao..." Song Zhengben asked tentatively.

Luo Yi said without hesitation: "There is no problem with Gao Kaidao. He advocates uniting against Sui Dynasty. If I agree to cooperate with you, he will agree. I can convince him. The key is how we cooperate. I think it is necessary to discuss the details."

Song Zhengben took out a document from his arms, placed it on the table, pushed it to Luo Yi, and said with a smile: "This is a specific plan we have proposed. Manager Luo might as well take a look. I will stay in Youzhou for three days. Specialize in discussing the details of the cooperation. However, there is one thing I want to remind Manager Luo that this matter must be kept absolutely confidential. I mean, I am worried that it will be leaked. If Yang Yuanqing knows, it will be detrimental to us."

Luo Yi nodded, "I understand this, don't worry!"

It was already very late at night. By the first update, the streets were empty and there was no pedestrian. Occasionally, a few tiny dogs ran past the streets and gathered together to bite them. They soon dispersed again. The weather was particularly cold, with dirty snow piled up everywhere, and the ice ridges under the eaves were two feet long.

On a small street northeast of Youzhou City, a tall and thin black shadow was walking hurriedly along the wall. He looked back and watched the changes in the surrounding situation. He walked across a street intersection and saw a wine shop not far ahead. His neck shrank and he accelerated his pace to walk towards the wine shop.

The wine shop is called Hongfeng wine shop. It is a very ordinary name. The wine shop is not big. It covers an area of ​​about one acre and two floors. There are many such wine shops in Youzhou City. Moreover, this location is not very good and looks a bit remote, so the business of the wine shop is not very good, and it closed early.

At this time, the door of the restaurant opened, and a friend walked out, followed by a middle-aged man, looking at his outfit, he looked like the shopkeeper of the restaurant.

"Shopkeeper, I'll go back first."

"Be careful on the road and take good care of your mother. If you can't come tomorrow, you can't come the day after tomorrow."

"I'll try to come tomorrow!"

The guy put his sheepskin coat on his body and said goodbye. The shopkeeper of the restaurant was about to go back, but in the dark, a tall and thin shadow flashed out.

"Who is it?" the shopkeeper was shocked.

"It's me!"

The shopkeeper looked left and right and quickly pulled the black and thin man into the restaurant. Under the light, this was a young man with dark skin, bright eyes, long arms, and very powerful.

This person is named Luo Shanwen. He was a spy sent by the Northern Sui Army to Youzhou. The shopkeeper of the wine shop was also a spy of the Northern Sui Army. His surname was Zhang. He opened this wine shop to cover him. They had been in Youzhou for two years and had collected a lot of information.

"Are you gaining anything?" Zhang Manager Zhang asked. He was responsible for passing on information. He knew that Luo Shanwen was so late, so he must have important information.

“There is an important piece of information!”

Luo Shanwen nodded, "We squatted in front of the General Administration's Office today and found that Dou Jiande's military advisor Song Zhengben arrived. After he entered Luo Yi's residence, he did not come out."

"Have you seen it clearly? It's Song Zhengben?"

Luo Shanwen nodded affirmatively and said, "I can be sure that it is Song Zhengben. This information is very important. I hope I can send it away as soon as possible."

"Okay! As soon as the city gate opens tomorrow, I will leave the city and release the eagles."
