Zhang Yi captured Xuyi, and Pan Zhang's side also took Huailing. Zhang Yi left Jiang Qin to defend these two county towns, and ordered Xu Sheng to lead the army to cruise in the upper reaches of the Huaishui River in order to meet Jiang Qin.

Zhang Yi repaired for a few days and once again entered Hongze Lake by boat. Zhang Yi's soldiers, after offensive training, all have a certain amount of water. Even if he didn't know how to swim, he could still take a boat, so that he could maximize the advantages of his sailors.

Zhang Yi landed directly in Sheyang from Hongze Lake, and then went directly to the east and arrived at the foot of Sheyang City.

In Sheyang City, Chen Deng and Yu Ban were confused by Zhang Yi again, and they didn't know why Zhang Yi had left for half a month. If Zhang Yi didn't appear, they might think that Zhang Yi had withdrawn from the army, but they didn't expect Zhang Yi to come back, so they had to think about where Zhang Yi had gone in the past half a month.

Chen Deng looked at the map of Xuzhou, scratched it at the place where Xu Yang handed over, and his finger stopped in the area of Xuyi Huailing.

After Yu Ban saw it, he asked puzzledly: "Do you think that Zhang Yi has captured Xuyi and Huailing in this half month?" ”

Chen Deng nodded: "It's only possible here." ”

Yu Ban said in wonder: "Forgive me for being stupid, although Xuyi Huailing is a place where grain is produced, Zhang Yi doesn't seem to be short of food, right?" ”

Chen Deng said: "Zhang Yi is indeed not short of food, but most of his grain is in Huainan (Jiujiang County, Jiujiang County is also called Huainan County, here refers to the county is not a region) Lujiang, and it is quite complicated to transport it. In particular, Dongyang and Ping'an counties were obtained by Zhang Yi, and the road was not very calm. Zhang Yi has the advantage of a naval army, as long as he takes Xuyi and Huailing, he can open up the waterway and transport grain directly from Shouchun. ”

Yu Ban gasped, "This Zhang Yi actually designed such a strategy, which makes people unable to guard against it." ”

Chen Deng said: "That's true, now that Zhang Yi has opened up the waterway, he can directly transport grain from Hongze Lake, and the land grain road is only thirty or forty miles, and it is impossible for us to rob grain." ”

Yu Ban said proudly: "The food in the city is enough to eat for a year, and the ban can guarantee that it can be kept for a year." ”

Chen Deng glanced at him and asked, "What about a year from now?" ”

Yu Ban was stunned for a moment, "Could it be that Zhang Yi can still attack for a year?" ”

"But he can besiege the city for a year!" Chen Deng said: "Now that the upper and lower reaches of Huaishui are occupied by Zhang Yi, even if Lord Sikong sends reinforcements, he will not be able to cross the river. ”

"Not necessarily!" Yu Ban said: "In another two or three months, the water level of Huaishui will drop to the lowest, and it may even freeze, and then the advantage of Zhang Yi's water army will no longer exist." ”

"It's time too! We can speculate. ”

Huaishui does not freeze in winter, which is a very serious problem. It's about winning or losing a war, or it can be about the rise or fall of a dynasty. However, the answer is very certain, this year's Huaishui will definitely freeze.

In ancient China, there were many periods when the climate was very cold, much colder than now. The coldest time was the Xiaoice River period of the Ming Dynasty, which directly caused various natural disasters, and many people did not have food, so they revolted one after another, becoming one of the most important conditions for the demise of the Ming Dynasty. If there were no natural disasters during this period, Li Zicheng, Zhang Xianzhong and others would not have so many people to support them, and they would not have been able to rebel.

The Three Kingdoms period was also a relatively cold period, and it was cold until the Eastern Jin Dynasty. This is why the Hu people began to occupy the north in the Eastern Jin Dynasty, and the Northern and Southern Dynasties appeared.

You must know that from the end of the Han Dynasty to the Three Kingdoms, even if it was an inseparable fight between Wei, Shu and Wu, the combat ability of the Hu people was not weakened at all. Cao Cao begged Wuhuan and governed the Huns; Sun Quan, Ping, Shanyue; Zhuge Liang collected the Southern Barbarians. The Qiang people in the Wuhu are swaying on both sides of Wei and Shu, the Qiang people are still just a small tribe, serving as mercenaries for various forces, and the Di people have not been separated from the Qiang people, and they should be called Baima Qiang at present. Only Xianbei is considered a big force, but Xianbei is even more divided than the Han Dynasty, and he is too busy to take care of himself.

Therefore, the Central Plains Dynasty has always suppressed the surrounding Hu people until after the Western Jin Dynasty. After the Western Jin Dynasty tossed itself to death, the Eastern Jin Dynasty retreated to the south. To tell the truth, it was not impossible for the Eastern Jin Dynasty to recover the lost territory, but the people at that time did not want to recover it at all! It was cold in the north and there was no food to eat. You must know that many people in Wuhu use people as military rations, in addition to psychopaths, there are also reasons why there is really no food to eat.

It is said that human flesh is sour, and there will not be so many perverts who like to eat human flesh. If there was grain in the north, the Eastern Jin Dynasty would not be able to let it go. You must know that most of the Beifu soldiers under Xie Xuan came from the north, if they didn't want to regain the lost territory? So many people in the Southern Song Dynasty advocated the Northern Expedition? No emperor was arrested in the Eastern Jin Dynasty, and the land that was beaten down was all owned by those families, and many of them were the ancestral lands of the northern families, and there was no resistance from top to bottom.

But we don't seem to have heard of the Northern Expedition in the Eastern Jin Dynasty, and the later Song, Qi, Liang and Chen all had the Northern Expedition, and Liu Yu, Chen Qingzhi, Tan Daoji and others all carried out the Northern Expedition.

Zhang Yi also felt that time was pressing, so after building the siege equipment, he immediately attacked the city, and he wanted to take advantage of the Huaishui before it froze, shoot the sun, and pull out all Cao Cao's strongholds in the south of Huaishui.

"Kill!" Zhang Yi's soldiers are also very warlike, Zhang Yi treats these soldiers very well, not only has a large amount of food, but also changes the way to increase their combat effectiveness, even if no one can make iron or leather armor, they will also make wooden armor, and the wooden armor after soaking in tung oil is also very strong. Of course, such armor is afraid of fire attack, but it is difficult to attack by fire during the siege of the city, so you need to pour oil and throw it down. Don't mention rockets, rockets at this time are even more difficult to get than torches and require a high level of technology.

Chen Deng and Yu Ban were both famous generals for a while, and they calmly organized soldiers to deal with Zhang Yi's various offensives.

Zhang Yi looked at the two generals on the city tower where the arrows couldn't shoot under the city.

"Yu Ban, Force: 91, Strategy: 97, Strategy: 87, Internal Affairs: 71, Education: 82, Diplomacy: 62. Trait: Handsome. ”

"Chen Deng, Force: 46, Strategy: 91, Strategy: 95, Internal Affairs: 91, Education: 83, Diplomacy: 90. Trait: Civil-military. ”

These two people are really heroes! Yu Ban Zhan Strategy actually had 97, and Chen Deng actually had four attributes on 90.

There are really not many people under Zhang Yi who can compare with them, only those famous generals and famous faces in history can compare with them. Cao Cao's subordinates have so many talents! If these people are used by me, how many years in advance will I agree with China!
