"What? Are you saying that the Shu thieves are attacking in two ways this time?! Moreover, the king of Yiyang also took the lead in folding for a while, losing seven or eight thousand soldiers and horses? You can't be mistaken, right? ”

"Military affairs, how dare subordinates deceive General Zhenxi. That's exactly what happened. So King Yiyang said that he would not be able to send reinforcements to the general in a short time. He also asked the general to do his best to deal with the Shu thieves with his existing forces. ”

"What about the Imperial Court?"

"The King of Yiyang has sent an envoy to gallop to Luoyang. But as of the date of the subordinate's return, the envoy from the imperial court has not yet come. ”

With a weak wave of his hand, after making the messenger retreat, Hu Fen sat down on his soft collapse.

At this time, it was already October 25th, and it had been twenty days since Jiang Wei trapped Shangqi.

"Hey, I'm so dizzy. Xishu's national strength has recovered very quickly over the years! Not to mention anything else, my Hu family's salt caravan has to pass through Wudu County in Xishu every month. That Wudu County is almost thriving day by day under my nose. This Wudu County is like this, do you still need to think about the situation in the entire Xishu? Why did I stubbornly think that the Shu thieves could only attack alone this time? ”

With a long sigh of annoyance, Hu Fen turned his head to Wang Shen and said, "Xuan Si, is Yao Kehui still unwilling to send troops?" ”

"That old thief has been pretending to be sick, and I can't even see his face!"

"This old horseman! If you are sick, you will be sick, but the food we sent is received with a smile! ”

"Humph! When Ben defeated Jiang Wei this time, he must turn his head and slaughter their entire clan! ”

After gritting his teeth and saying a threat that he felt was ethereal, Hu Fenqiang beat his spirit: "Everyone, the situation is very dangerous now. No matter how insufficient our troops are, we must send troops to rescue Shangdi. But before we go to Shangtai, we have one more thing to do. ”

"Please show me the general."

"Street Pavilion! Ladies and gentlemen, according to the intelligence, the Shu thieves have a total of about 120,000 troops from the two routes this time, which can be said to be from the empty country. But this number of troops is still too much and insufficient compared to my Great Jin. Therefore, the strategy of the Shu thieves in Longxi must be to attack the street pavilion after taking Shangqi. Then block the reinforcements sent by the imperial court to Longxi. Therefore, the general's arrangement is: the 40,000 people who are now concentrated in Jicheng are divided into two routes. All the way to the street pavilion, all the way with the general to Shangtai to look for fighters. ”

After Wang Shen and the others exchanged glances with each other, they all bowed down: "The general has made good arrangements." ”

"Good, then, please ask Ji Wei to lead five thousand infantry and five thousand cavalry to gallop through the street pavilion. Hey, that place has not been repaired since Zhang Junyi destroyed it back then, and Ji Wei went there, but it was not easy at all. ”

Hearing Hu Fen's words, Wen Hu also felt a toothache: "The last general, do your best!" ”

"Well, Ben General's team has 20,000 cavalry and 10,000 infantry. I will try my best to deal with Jiang Wei and buy time for Ji Wei to repair the castle as much as possible. ”

"Thank you, General, in this way, the last general will go down to the whole team."

"Hehehe, go together. We're going to go to Shangtai sooner. Counting the time, there are still seven or eight days before Jiang Wei's embankment should be used. ”

……

Just five days before Hu Fen finally made up his mind to send troops, on November 20, outside the city of Shangqi.

"Still haven't you seen Hu Fen's army?"

"Returning to the general, the scouts in front have already advanced to twenty miles south of Jicheng, and there is still no sign of the enemy's army moving south."

"Hey! This Hu Xuanchong is really like a stone. Order, all the engineer battalions retreat, and prepare to destroy the dam. ”

"No!"

In fact, saying that Hu Fenxin is like an iron stone still wronged him. The crux of the problem is that as a contemporary who has never seen cement, Hu Fen never knew that after having this thing, Jiang Weijun had to block a river with a width of no more than 100 meters, and its construction time could be saved by half!

"It's all scattered, scattered!" Commanding the dam construction site was Guan Yi's student Li Xiang. This kid is now full of unhappiness: what if he said that he would be promoted if he set up a good flying rope? Well, the officer was promoted - engineer captain. What the hell is this? Soldiers don't lift knives to kill people, and they build bridges and pave roads every day, and are they considered soldiers? Okay, this Northern Expedition will take me to Guanzhong to find the sister of the family? As a result, they kicked me to Longxi......

There were constant broken thoughts in his heart, but Li Xiang's movements were not slow. With his command, the hundreds of soldiers of the engineer battalion on the bank of the river vigorously rotated the huge winch, and the ropes at the upper ends of the two largest prefabricated boards that had blocked the Jinghe River gradually tightened. Finally the two prefabricated slabs were dragged out of place.

Immediately afterwards, several soldiers from the engineer battalion poured a bowl of ginger soup, took off their clothes, and plunged into the water. The ropes extending from the winch were hung on the iron rings preset at the tops of the two other prefabricated slabs under the water....... and this was repeated two or three times, and the cement prefabricated slabs that really blocked the entire dam were quickly removed.

Behind the prefabricated slabs is a thin layer of dam made of wooden strips and mud. Without the hard precast cement slabs in front of it, the dam could not withstand the tremendous pressure of hundreds of tons of river water at tens of meters high, and at a speed visible to the naked eye, the dam leaked in one place, then in several places, and finally, with a loud bang, the entire dam collapsed completely. The river water that had been stored for a long time, with huge potential energy, was like a dragon that had been imprisoned for a long time and could finally run freely, roaring towards the Shangqi city wall!

This huge flow of water, guided by the guide trough built by the engineer battalion with cement in advance, slammed into the west wall of Shangtai City with rapid speed and great kinetic energy. Its strength was sufficient, and in that instant, the entire western wall of Shangtai City shook slightly. Duan Zhuo, who was watching all this happen on Shangqi City, accidentally fell on the city wall.

"General be careful!"

"General, I might as well kill it together now, so I can take the heads of a few Shu thieves on my back!"

"Yes, general, I'm not afraid of death, and ask the general to take me out to kill!"

"Hey~~~" Seeing that his subordinates were still full of fighting spirit in such a desperate situation, Duan Zhuo felt ashamed at the same time: "Everyone, it's not that I don't take you out of the way." But now we can't rush out if we want to. ”

Why is that? Because, Jiang Wei's water attack on Shangqi was not simply to build a dam on the Jinghe River, and then use the huge water energy after the gate was opened to impact the city wall.

Before the dam was opened, Jiang Wei had already ordered the people who accompanied the army to start a circle of low embankments around the Shangqi city wall.

The embankment is very low, and the waterproofness is completely unreliable. However, with the existence of this circle of embankments, after being guided to the vicinity of the Shangqi city wall, the Jinghe River water will not retreat quickly while violently washing the city wall, but will stay in this circle of embankments for a short time. Although a large amount of water leaks from here every day due to the quality of the embankment, the remaining amount of water is still enough to soak the foundation of the Shangtai city wall for three to five days.

That's enough.

The city walls of this era were all rammed earth walls. The rammed earth walls themselves are not very afraid of water (otherwise they will collapse when it rains). But there is a requirement: the water area of the entire wall should be relatively uniform, and at the same time, after a large amount of water (such as rain), the water should be quickly drained away.

Now, due to the low embankment around the city walls, the entire foundation of the city is submerged in water. No matter how tightly the wall was built at the beginning, in the face of the water molecules, the entire city foundation would become soft in three to five days. At the same time, the foundation of the city was unusually flooded, causing the foundation to expand unilaterally, while the upper wall remained dry......

On October 25, that is, when Hu Fen made the decision to send troops in Jicheng. The western wall of the castle was finally overwhelmed by the loosening of the foundation, and there was a partial collapse.

"Almost, Ji Ren!"

"The end will be."

"You personally go to the embankment on the east side of the city, tear it down, and divert water into the Jing River again."

"No! Xiang Chong received the order. ”

"Xuangao, Dianbo."

"The end will be."

"The two of you will lead the Tiger Infantry Army forward, and when the water is drained away, you will approach the city wall and dig the foundation."

"No! We will receive the command. ”

"Zicheng!"

"The end will be."

"Lead the crossbow team forward to provide cover for Xuangao and Dianbo."

"Come and be faithful!"

With Jiang Wei's repeated orders, the entire Shu Han army moved in an orderly manner.

"Jiang Boyo, I hate not to eat your meat raw!" Seeing that the water level under the city was gradually decreasing, nearly 10,000 Han troops approached the city wall with various wall-digging tools. Duan Zhuo knew very well in his heart that this Shangcheng was lost.

After gritting his teeth and scolding Jiang Wei, Duan Zhuo turned to his lieutenant and military marquis and said, "Everyone, this city is about to be destroyed. Originally, with today's situation, we should retreat from the city wall and enter the city to engage in street battles with the Shu thieves, which will definitely be able to inflict maximum damage on the other side. But now there are nearly 10,000 people in the city, besides us. So, Ben decided to open the door and rush out. If you go this time, you will definitely die, so Ben will not force you to rush out with Ben Jiang. Whoever is willing to go, go down and prepare the army and horses. If you don't want to go, maintain order in the city, and don't let the people in the city take this opportunity to harm the people! After Ben is killed, you can surrender! ”

……

On October 25, 267 AD, the city of Shangtai was about to be broken. The defender Duan Zhuo led more than 7,000 defenders to rush out, and the whole army was killed!

The city of Shangtai then fell. Zhang Yijun began to advance in the northwest direction.

At this time, Hu Fenjun had just driven out of Jicheng.
