After listening to Jia Xu's analysis, Cao Cao was relieved. Although Jia Xu was not sure whether it was Qingzhou or Yanzhou in the end, he had greatly shortened the scope of Cao Cao. Although Cao Cao's military strength is still not as good as Sun Jian's, if we can determine the specific target, Cao Cao can still resist by focusing on defense.

After unifying the north, under Jia Xu's suggestion, Cao Cao also began to establish his own intelligence network. At this time, Cao Cao discovered that Sun Jian had planted so many detailed works in the north, which really made Cao Cao wipe a cold sweat. Cao Cao really realized that the strength of Soochow was far above his imagination. After several overt and covert battles and the cooperation of the local Cao army, most of Sun Jian's detailed works were finally driven out of the north, and a small number of detailed works had to be gradually eliminated, but at least Cao Cao could be relieved to start his deployment.

Now that Jia Xu has narrowed the scope of prevention to Yanzhou and Qingzhou, Cao Cao has begun to make arrangements to support the two states. Just as Cao Cao had just finished his defense plan, a young man came out of the ranks of civil servants and bowed his hand to Cao Cao and said, "my Lord! I have a plan to offer to the Lord! "

Cao Cao looked at it, but he hired a counselor last year. He was the son of Sima family in Hebei Province. His name was Sima Yi, and his name was Zhongda. When hiring this man, Cao Cao asked Jia Xu to take the place of himself. Later, Jia Xu replied to Cao Cao and said, "this man is a genius in the world." Naturally, Cao Cao believed in Jia Xu, so he also attached great importance to Sima Yi. Now Sima Yi suddenly offered a plot, which was also the first strategy Sima Yi made after joining the Cao army camp. Cao Cao also attached great importance to it.

"Zhongda? Tell me what you have in mind Cao Cao said with a smile.

Sima Yi said to Cao Cao: "just now, according to the words of Lord Jia, the eastern Wu Kingdom will take revenge for the fact that our army sent troops to Xuzhou this time. Therefore, they actively took precautions. But my subordinates think that this is the real opportunity for our army to attack Soochow! "

"Ah?" Cao Cao looked at Sima Yi strangely and asked, "Dongwu is powerful. If they start to attack, we should do our best to defend! Why did Zhong Da say that it was a great opportunity to attack Soochow? "

Cao Cao's question is also the question of everyone. Except Jia Xu, who seems to have thought of something silent, others are looking at Sima Yi with questioning eyes. Although Sima Yi was young, she did not feel uncomfortable in the eyes of the public. Instead, she was enjoying herself. Sima Yi said, "as the LORD said, when the eastern Wu started fighting for revenge, all the people in the world expected that we would try our best to resist it in the Northern Wei Dynasty, and Dongwu itself was no exception. Then, if we suddenly send troops at this time, we will not be prepared to attack them! "

"Wonderful!" Before Sima Yi had finished speaking, Jia Xu also figured out the joints. He could not help but drink, and turned to Cao Cao and said, "Lord! What a wonderful plan Zhong Da has

Cao Cao also turned Sima Yi's plan in his head. His eyes began to shine, and he quickly continued to ask, "it's reasonable indeed! Now that Zhongda has come up with such a plan, it must be decided where we should attack Soochow! "

Sima Yi was not modest, and immediately gave Cao Cao An Analysis: "if his subordinates have not guessed wrong, I think it will not be a few days, then the eastern Wu will send Jingzhou army to Hangu pass! The Lord is carefree, but this action of Soochow is not to let the Jingzhou army attack, but to make the Xuzhou army attack as a cover. Once Jingzhou army is stationed in Hangu pass, the Lord can start from Yuzhou! If you can take advantage of the chaos and seize Yuzhou, it will be of great benefit to the Lord in the future against Dongwu! "

Speaking of this, Sima Yi stopped for a meal, swept the people around, and saw that all the people were looking at him, and couldn't help smiling. Then she continued: "firstly, the land of Yuzhou is fertile, and the annual supply of grain and grass is not much less than that of Xuzhou. Seizing Yuzhou can provide logistical support for the Lord to build a more powerful army in the future 2、 Yuzhou is located at the junction of Yanzhou, Bingzhou and Yongzhou, and there are Jingzhou and Yangzhou in the south. It is indeed the best outpost for the Lord to march into Dongwu in the future. Thirdly, if Yuzhou is captured, the logistics of Jingzhou army at Hangu pass will be completely cut off by our army. At that time, the Lord will come back to join the two armies. The Jingzhou legion, which is known as the three armies of Dongwu, is bound to be It's gone

After Sima Yi finished three o'clock, there were bursts of cold air in the whole chamber. Everyone looked at Sima Yi with strange eyes. I didn't expect that Sima Yi was so young, so insidious and vicious that she was no less than the old-fashioned Jia Xu. Jia Xu frowned a little at Sima Yi. When he took the examination of Sima Yi before, he had already realized that the ambition in his heart was not small, but Cao Cao's ability could still suppress him. But I didn't expect that Sima Yi's ability was much better than he thought, and Cao Cao could deal with it. But if Cao Cao's successor was not as strong as Cao Cao's, I'm afraid that Sima Yi would become a disaster of the Northern Wei Dynasty.

However, it is useless to think too much now. Sima Yi's ability is exactly what Cao Cao needs now. However, Jia Xu made a secret decision. Once Sima Yi's power is too big to suppress, Jia Xu must eliminate this person first!

Naturally, Cao Cao and Sima Yi didn't know Jia Xu's intention. Cao Cao, who had already approved Sima Yi's plan, swept away the depression before him and said with a big wave of his hand: "very good! Everything will be done according to Zhongda's plan! "——Outside the Donghai city of Qingzhou, Chen YangZheng and his army horses were ambushing in the woods beside the city. This Donghai city is a big city adjacent to Xuzhou. Cao Zhang, a general sent by Cao Cao to Qingzhou, stationed about 50000 troops in this city, which is definitely not an easy city to attack.

It is said that Chen Yang followed Bao Bao to go to Qingzhou at the order of Sun Jian, and temporarily mobilized about 200000 people from Xuzhou, leaving 100000 people to stay in Xuzhou. Bao Bao took the 200000 yuan to xiapi on the edge of Qingzhou. However, Qingzhou is not easy to attack. Unlike Xuzhou, Qingzhou has so many cities that it is not suitable to attack one by one. So Baobao divided the army into three parts: 50000 troops to Chen Yang to March eastward and 50000 troops to Sun Yi to march westward, while Bao Bao himself led Lu Xun and 100000 troops directly to Linzi City, the capital of Qingzhou.

Chen Yang led the army alone for the first time. However, Chen Yang was not nervous at all. Some were excited about the war. After setting out from xiapi, Chen Yang ordered the army to rest during the day and rush on the road at night to conceal the troops' movements as far as possible. Chen Yang was not worried about the speed of the March. Although he attacked the nearest city in Xuzhou, he did not intend to fight the first battle. It took Chen Yang three days to get to the East China Sea, which was only a day's journey.

Even when he arrived at Donghai City, Chen Yang still did not attack Donghai city. Instead, he hid all the 50000 people in the woods outside the city. He was not allowed to make a fire to cook every day, but only ate the prepared dry food. This is because Chen Yang is waiting for the moment when the battle between the other two sides starts.

Sure enough, on the fourth day of Chen Yang's arrival in Donghai City, Chen Yang sent spies to the west of Donghai city to report that several groups of people rushed into the city successively. As soon as Chen Yang got the news, he immediately guessed that it must be the military information from Bao Bao and Sun Yi attacking Teng city and Philadelphia.

Tengcheng and Philadelphia are also Qingzhou's two cities, but their scale is far less than that of Donghai, and because they are far away from Xuzhou, there are not as many soldiers as Donghai. For Bao Bao and Sun Yi, it is not difficult to capture these two cities. The two cities suddenly attacked will surely rush to Donghai city for help, and Chen Yang, waiting for reinforcements from the East China Sea!

After getting the news, Chen Yang quickly ordered the soldiers to rest well and get ready to go. He quietly walked out of the woods and gradually disappeared in the night.

The next day, as Chen Yang had expected, a troop of about 40000 people had been surging out of Donghai city. It was not other people who led the troops, but Zhu Ling, the governor of Donghai City appointed by Cao Zhang. As soon as the team left Donghai City, they went directly to Philadelphia. According to the letter for help received by Zhu Ling yesterday, Philadelphia was attacked by Bao Bao Bao himself. At this time, the situation was in danger, so he asked Zhu Ling for help urgently. When he got the letter, Zhu Ling hesitated. After all, according to the truth, Donghai city is the closest to Xuzhou, so we should fight Donghai first! Is this guarantee not afraid of being cut off?

However, this day has not passed, and another letter for help has been sent to Zhu Ling. This time, Teng Cheng is asking for help. This time, Zhu Ling is relieved. In his opinion, this Baobao should be based on the idea that soldiers should be divided into two routes. Even if Donghai city sent troops to cut off the back road, Baobao could also let the troops attacking Tengcheng come back to rescue. The two teams of people and horses help each other, so they are not afraid of logistics failure. Donghai can't sit back and ignore it at this time. If the Xuzhou army goes all the way north to capture the city of Lu, Baobao will only need to kill a gun, and Donghai city will become an isolated city and will be occupied sooner or later.

Having figured out this point, Zhu Ling began to gather people and horses that night and prepared for the whole night. In the early morning of the next day, Zhu Ling set out to go to Philadelphia for rescue. In Zhu Ling's plan, after rescuing Philadelphia, he was not in a hurry to rescue Teng city. At that time, he only needed to cut off the back of the team that attacked Teng City, and then the Xuzhou army would not attack itself.
