Shortly after the Sui army secretly withdrew from Mengyin Fort, a Sui army of about 8,000 people quickly left Dong'an County and headed southwest, with clear targets pointing to Zhuanyu County, Wang Bo's old nest.

In the night, the Sui army moved quickly. At the front were five hundred cavalry, behind were neat Sui infantry, without a logistics convoy. Each soldier marched silently with a bag of dry food on his back. No one spoke or left behind. The soldiers' armor in the moonlight reflected the cold light, and the spears carried on their shoulders shone coldly, and the team looked particularly murderous.

This is the main force of the Sui army going to fight. You can see the Sui army commander Zhang Xuan in the middle. Among the cavalry in front, there is Pei Xingyan, and Yuchi Gong holding a big iron spear in the back.

Shortly after the Sui army left Dong'an County, they were immediately discovered by spies ambushed near Dong'an County, including Sun Xuanya's spies and Wang Bo's spies. They immediately sent this important information back to their nests with an eagle letter.

Two eagles spread their wings in the air and flew towards Zhuanyu County and Fei County respectively.

Since Wang Bo went north to attack and lost tens of thousands of people, he has completely silently. Wang Bo originally had 20,000 troops, and thought he could rely on these 20,000 troops to capture a territory and become a prince, but he never expected that his seamless plan would fail, losing his most elite 10,000 soldiers and escaping less than a thousand remaining troops.

At this time, Wang Bo only had 10,000 people left. These 10,000 people were recruited locally. They were not trained enough, had weak combat power, and their morale began to be unstable. The consequences of the devastating defeat in Lu County began to emerge gradually, and there was a phenomenon of escape among the soldiers, which made Wang Bo extremely anxious.

He began to consider leaving Langya County and going elsewhere to develop, but the war in the Central Plains was also fierce. He originally planned to defect to Wagang, but now it has become unrealistic.

But the cunning rabbit has three caves, so Wang Bo cannot leave a way out for him. Shortly after he was defeated and fled back to Zhuanyu County, he sent his brother-in-law Xu Shunming to lead three thousand troops into Lu County, where the Sui army was weak, and sent his family to the Fangshan Xinshan Village near Qufu. That was the retreat he had prepared long ago. Once Zhuanyu County could not defend, he would immediately withdraw back to Lu County.

Wang Bo’s greatest hope is that the Sui army will attack Sun Xuanya first, give him some breathing opportunity, so that he can have time to transfer the last part of the materials, money and food, and be able to train the army. Time is extremely precious to him.

But often things don't go as they wish. Just when Wang Bo secretly prayed that the Sui army would attack Sun Xuanya first, he received an emergency eagle letter from a spy from Dong'an County. A Sui army with nearly 10,000 people was quickly coming to Zhuanyu County.

In the lobby, Wang Bo didn't say a word for a long time. Yingxin fell from his hand. He looked straight ahead, as if he was struck by lightning. His whole person turned into a sculpture, and he was already in ashes.

"King! King!"

His confidant general Liu Haochun advised: "It's time to come, so it's better to think about countermeasures urgently. Perhaps we can withstand this disaster."

Wang Bo finally recovered. He sighed, "I regretted not taking the risk of sending troops to Qi County. This led to the loss of my elite troops. Now there are only 7,000 people in the city, with poor morale and weak combat power. How can I resist the large-scale attack of the Sui army?"

"King, maybe the Sui army brought insufficient food. As long as we stick to the city and wait until the Sui army is exhausted, they will naturally withdraw their troops."

Wang Bo shook his head, "If Xintai County was not lost, we might have this opportunity. But Xintai County was also lost. The Sui army would definitely transport grain from Xintai County to the south. How could Zhang Xuan have imagined this problem?"

As soon as he finished speaking, a soldier rushed to the hall to report: "Report to the king, news came from Xintai County that a grain team had set out from Xintai County and headed towards our Zhuanyu County."

Wang Bo showed a bitter smile on his face and said to Liu Haochun: "See, the Sui army's food supplies have been released. They set out from Dong'an County without supplies, just to march quickly. The real food supplies were in Xintai County, which I expected."

"Then Beizhi is willing to lead an army to ambush the grain team. As long as the ambush is successful, the Sui army can only withdraw its troops!"

"You're thinking too simple!"

Wang Bo sneered and said, "You want to get it, didn't Zhang Xuan think of it? He would repeat Pei Renji's mistakes? If you ambush the grain, you will only be intercepted by the Sui army, just as Zhang Xuan's intention."

Liu Haochun lowered his head and did not dare to say anything. Wang Bo took a few steps with his hands behind his back and said resolutely: "The current strategy is to use the strategy of surrounding Wei to save Zhao and ask Sun Xuanya to send troops to attack Mengyin Fort or Dong'an County. Only then can Zhang Xuan withdraw his troops and relieve the danger of Zhuanyu County."

"But......"

Liu Haochun said helplessly: "I'm afraid Sun Xuanya is still angry about our sneak attack on Qi County and refuses to send troops to help. Moreover, Bei Zhi feels that he also hopes that the Sui army will attack us first."

"This won't be. My lips are dead and my teeth are cold. If I am destroyed, it will not be a good thing for him. I can retreat to Lu County. Where can he retreat? I believe Sun Xuanya understands this principle, but..."

Wang Bo also knew that his sneak attack on Qi County angered Sun Xuanya. It was indeed difficult to calm Sun Xuanya's dissatisfaction with a letter alone. Well, he couldn't bear to bear the child and could not beat the wolf. Wang Bo knew very well that Sun Xuanya had always wanted his concubine Huang Meiniang, so he gave Huang Meiniang to him.

Thinking of this, Wang Bo immediately wrote a letter, found his own personal soldiers, handed the letter to him, and told him a few more words.

The personal soldiers nodded and went immediately.

Half an hour later, fifty Wang Bo's personal soldiers guarded a carriage and drove westward. The carriage was Wang Bo's beloved concubine Huang Meiniang. In order to get Sun Xuanya to send troops, Wang Bo also took the initiative.

The next afternoon, the main force of the Sui army arrived in Zhuanyu County, but they did not launch an attack immediately, but built a camp five miles away from Zhuanyu County. They seemed to be waiting for the arrival of the grain trucks in Xintai County.

............

Fei County, while Wang Bo received the news that the Sui army sent troops, Sun Xuanya also received the news that the Sui army sent troops to Zhuanyu County, which immediately made him feel relieved. Of course, it was natural to attack Zhuanyu County. Zhang Xuan wiped out Wang Bo's elite main force in Lu County and took the opportunity to capture Xintai County.

This is the time when Wang Bo is the weakest. It is indeed a bit unreasonable for Zhang Xuan not to beat Wang Bo, but Wang Bo will inevitably ask for help from him. What should he do? Sun Xuanya couldn't get an idea for a while.

Just when Sun Xuanya was hesitating, his brother Sun Zhian came to the hall and bowed and said, "Are you still worried about the Sui army sending troops to Zhuanyu County?"

Sun Xuanya smiled bitterly, "What do Erlang thinks?"

Sun Zhian walked into the hall and said to Sun Xuanya: "Since the elder brother also knows that his lips and teeth are cold, why don't he take the opportunity to attack Mengyin Castle and take down this confidant's trouble?"

Sun Xuanya sighed, "I just can't figure out why the Sui army withdrew from Mengyin Fort? I think there is something strange here. Since the Sui army is going to attack Zhuanyu County, it should strengthen the defense of Mengyin Fort. How could it reduce its garrison instead? It's a bit unreasonable!"

"Maybe this is Zhang Xuan's plan to doubt the soldiers, which makes the eldest brother feel unreasonable, so he dare not act rashly."

"Impossible!"

Sun Xuanya shook her head, "This kind of suspicious military strategy is too risky, so there is no need for Zhang Xuan to take this risk."

Sun Zhian was silent for a moment, "Don't you think Zhang Xuan's troops in Zhuanyu County are hasty this time?"

"Why do you say that?"

"I feel that Zhang Xuan is not fully prepared. He started an offensive without even finding all the mule drivers. I feel that he is going to fight quickly."

Sun Xuanya still couldn't figure out what his brother meant. He frowned slightly, "What the hell do you want to say?"

"Brother, I want to say that Zhang Xuan is likely to have insufficient troops. He withdrew from Mengyin Fort. It is likely that the army has transferred back to Beihai County and Qi County. Have you forgotten Wang Shichong?"

Sun Xuanya suddenly realized, "Are you saying that Wang Shichong taking the opportunity to plunder Qi County and Beihai County again?"

"That's what I mean. Since the Emperor of the Sui Dynasty did not punish Wang Shichong, it was equivalent to acquiescing his actions. With Wang Shichong's greed, this time Zhang Xuan fought south and Pei Renji went to attack the Wagang army again. Qi County and Beihai County were empty. Wang Shichong would not miss this opportunity and would definitely go south to plunder again. Therefore, Zhang Xuan rushed to send troops to Zhuanyu County. He wanted to destroy Wang Bo and give the court an explanation, and then he would withdraw his troops and return north."

Sun Xuanya paced back and forth in the lobby with his hands behind his back. He was very excited. If this was the case, Zhang Xuan would not be able to attack him. He began to become active, and his original doubts gradually disappeared. He actually forgot about Wang Shichong, which is an important factor. Could it be that Zhang Xuan secretly withdraws troops from Mengyin Fort and must have returned to defend Beihai County?

"Brother, we can really attack Mengyin Castle, there is a rare opportunity!"
