The coalition forces began to dig trenches, and more than 100,000 people dug together, digging one kilometer a day, and it was really a piece of cake.

Seeing that it will be dug under Luoyang City in a few days, as soon as the water is released, Luoyang City is not coated with waterproof coating, and it is a matter of time before it is flooded. If the water is flooded, it will not be able to hold the city 100%, there is no doubt about it.

A day later.

Cao Cao was anxious in the conference hall, looking at Gao Yuan and sighing, looking at Guo Jia and others sighing.

Gao Yuan was silent, because the allies were at a disadvantage in terms of strength against the coalition forces, and the other party wanted to do something outside, and it was impossible to stop it.

Sima Yi said behind his back: "My lord, Yuan Shao actually used this kind of poisonous trick that hurts heaven and reason, and hundreds of thousands of people in Luoyang are not protected day and night, and it is almost time for us to go back." Although the south bank of Mengjin is occupied by Yuan Shao, we can retreat to Hangu Pass and return to Xiexian from Xinfeng Port to Bingzhou. ”

This strategy is too poisonous, and if you want to make a big flood, the high-tech in the future market can't stop it, let alone now. Even if Guo Jia, Sima Yi and others are super resourceful, they are helpless against such a poisonous plan under the disadvantage.

If Gao Yuan leaves, it is estimated that Cao Cao will be gone.

Cao Cao seemed to see something, grabbed Gao Yuan's hand, and suddenly changed from a hero to a poor old man, and said, "Meng Yan, you can't abandon me." We're all counting on you. ”

Gao Yuan grinned, and said in his heart When you came to my side to sabotage two years ago, you didn't say that.

Of course, at that time, we were not a family.

Gao Yuan came to the Eastern Han Dynasty alone, and was very reluctant to feel the warmth of a large family. On the other hand, strategically, Cao Cao could not be completely defeated.

At this time, Guo Jia said: "You may take the initiative to attack and disrupt the excavation process of the coalition forces." ”

There is no way to do it.

Therefore. The Allied army of 50,000 left the city and went straight to the south bank of Mengjin.

On the side of the coalition forces, Mengjin excavated the site.

I saw that the river dug by the coalition forces was already four miles away.

A large amount of soil was excavated, and Yuan Shao did not waste it, so he used this soil. A number of earth sealing platforms were erected on both sides of the artificial river. Each one was as high as a five-story building, with a flat top and a width of five hundred square meters, capable of standing two or three hundred archers.

As far as the eye can see, on both sides of the river, all of them are this kind of soil sealing platform. The role is self-evident in the excavation work to protect the river.

Yuan Shao was on the front of the sealing platform, looking at the huge body of Luoyang City in the distance, and said to the left and right: "Within six days." Dig under the city of Luoyang. Open the floodgates here to release the water, and ask for the lives of Cao Mengde and Gao Mengyan! ”

Because Yuan Shao wanted to release the water slowly, he was able to control the breach area. After destroying the allies, Luoyang was safely owned by him.

Liu Bei and Cai Mao felt that this was a good plan.

At this moment, all of a sudden, the dust rose in the direction of Luoyang City, and a coalition army came from a nearby horse. He raised his head under the sealing platform and shouted: "Lord, Luoyang City has killed the allies." It is estimated that there are 50,000 soldiers and horses. ”

When Yuan Shao heard this, he laughed and said, "Cao Mengde can't sit still!" He stepped on the sturdy earth sealing platform under his feet, "I have already prepared here, so let Cao Mengde also know the difficulty of attacking the fortification, pass on my orders, and blow the horn!" ”

Suddenly. The sound of the trumpet shook the sky. The soldiers who had been digging the river put down their tools one after another and picked up the weapons piled together. The archers and a small number of infantry went up to the sealing platform, and the infantry gathered in the space between the sealing platforms, and used the earth under the platform. Immediately, between the platforms, a small earthen wall one meter high was piled up to block the cavalry assault.

There are high platforms and earthen walls. There were archers on the high platform, and spearmen behind the earthen walls, and the defense was really tight. On every platform, there are generals. What Yan Liang, Wen Chou, Zhang He, Zang Ba, Wen Ping and others are also in command.

Therefore, when Gao Yuan and Cao Cao came, they looked at the two rows of sealing platforms across the river, which was equivalent to a king-size arrow tower, and their hearts sank to the bottom.

In fact, they also got the news that there was a sealed soil platform, but after seeing it at the scene, they were even more shocked.

Gao Yuan frowned, turned the halberd in his hand, and said, "Uncle Yue, Yuan Shao is fully prepared, so don't attack." Let's go back and think of something else. ”

Cao Cao and his advisers have been pondering for several days, but there is no way, and if they don't attack, it will be too late. Therefore, Cao Cao had to try to attack no matter what. So, he issued an order for the onslaught of the whole army.

For a time, the shouts of killing filled the south bank of the Yellow River.

I saw that on the sealing platform of the coalition army, a rain of arrows like locusts was shot wildly. Shot too many Cao soldiers to death under the sealing platform. The coalition soldiers on the stage were condescending and stabbed, and the Cao soldiers could hardly go up. It was also shot into a hedgehog by hundreds of archers.

And Cao's army attacked Taizi again, and encountered a frantic counterattack by the allied infantry. The coalition soldiers didn't need to move, they stabbed their spears behind the small earthen wall, and a string of stabs was a string.

Although the archers of the Cao army also launched a fierce fire, the archers of the Yuan army were condescending and soon completely suppressed the archers of the Cao army.

Half an hour later, Cao's army only captured three fiefdoms, but it lost as many as five or six thousand soldiers. And there are more than 30 such fiefdom platforms in Yuan Jun.

Gao Yuan did not let his soldiers die, in his opinion, this earthen platform is connected one by one, which is the tower defense, and Cao Jun is the poor invader. The infantry blocked and all the archers were killed.

He was very distressed by the fearlessness of Cao Jun's soldiers, and couldn't help but say, "Lord Yue, you can't sacrifice like this!" ”

Cao Cao showed his true colors, "Take him ten soil sealing platforms, I am here, confront Yuan Shao, he will not be able to dig a ditch." ”

This idea was good, but the news that came later shattered Cao Cao's illusions.

"Report ......, lord, the coalition army of 150,000 is approaching Luoyang City!"

With the arrival of this news, Cao Cao's face changed drastically. Only then did he think that if he confronted Yuan Jun here, Luoyang City would have no soldiers and horses to protect it. For a time, the superiority of the coalition forces was reflected to the greatest extent, and Cao Cao could not take care of the end.

"Uncle Yue, if you don't withdraw, it's too late?" Gao Yuan said coldly. It's not that he is afraid of fighting, but that such operations are already tasteless.

Cao Cao was immediately disheartened, and ordered Mingjin to retreat.

Yuan Shao was overjoyed, and on the nearest sealing platform, he shouted: "Brother Meng De, sooner or later, one day, we will meet in Luoyang City, at that time, my father invited you to drink and talk about the friendship for many years." ”

Cao Cao was furious, but had no choice but to retreat to Luoyang.

And Yuan Shao didn't chase after him, because he had a way to surrender his soldiers without fighting, so why should he lose his soldiers. At this point, the coalition forces attacking Luoyang also retreated.

Gao Yuan and Cao Cao returned to the mansion, because there was nothing they could do, so they were bored, and each returned to their respective residences with worries.

After Gao Yuan returned to his compound, he immediately summoned Sima Yi and others to a meeting.

At the meeting, Sima Yi still said: "Lord, let's go." Defend the annexation, gather strength, and wait for the opportunity. He also analyzed: "Our annex is different from Luoyang, a land that is attacked on all sides, and our people are also different from the people here, and there will never be a result like Cao Cao." ”

Just when Gao Yuan was hesitating, a messenger came from Bingzhou and brought Chen Lin's letter.

Gao Yuan opened it and looked at it, his face changed greatly, "It's not good, there is a flood peak in the upper reaches of the Yellow River!" ”

When everyone heard this, their hearts were shocked. The news of this flood peak, that is, the Yellow River will be flooded and flooded this year. Wherever Hong Feng goes, there is a Ze country. It is a certainty that the grass will not grow, the people will suffer, and the displacement of millions of people will be assured. (To be continued......)
