The army that Sun Jianjun saw outside Xuchang City was naturally the 5,000 reinforcements brought by Gao Shun.

As for why the 5,000-strong army seems to have the feeling of 40,000 or 50,000 troops, in fact, the answer is very simple, it is nothing more than tying branches and other things to the legs of the war horses, so that they can raise endless dust in the process of advancing, so that people will mistakenly think that there is a strategy such as the arrival of a large army when they look at it from afar.

This is Guo Jia's strategy - the strategy of doubting the army, to make Sun Jianjun think that the number of reinforcements is quite large, so that he has concerns, so that he can smoothly delay the time of his siege.

For this reason, Guo Jia also suggested that Cao Cao let Gao Shun take all the cavalry away. After all, only a small half of the 1,000 cavalry troops brought to Guandu are now left, and they can hardly play a role on the battlefield of Guandu, so it is better to use them well elsewhere - even if it is just to tie branches to the horse's legs for the purpose of suspicious soldiers.

An excellent cavalry team is usually one person with three horses, Cao Cao's conditions are not so sufficient at this time, but one person and two horses must be absolutely guaranteed, so Gao Shun brought back more than 800 horses to Xuchang. The eight hundred horses were tied to the legs of the horses, and the smoke and dust that could be raised was quite powerful.

In another time and space, Zhang Fei used this strategy in front of the Nagasaka Bridge, when he only asked his subordinates to use a dozen horses to raise smoke and dust, which made Cao Cao mistakenly believe that there was an ambush and did not dare to enter.

If Cao Cao knew that there were really only Zhang Fei and a dozen of his men on the other side of the Changsaka Bridge, even if Zhang Fei's voice was loud and useless, Cao Cao's army would have crushed you into slag long ago.

As for the reason why the support army chose to camp outside the city instead of entering the city to help the garrison, this reason is also very simple. If you choose to camp, you can arrange it in many ways, so that Sun Jianjun will continue to misunderstand and think that there are a lot of reinforcements. But once the army enters the city, its movements may be observed by Sun Jianjun, so as to know the details of the number of reinforcements through scouts and other channels.

Even if there are 5,000 more people, Xuchang's guardian strength is still insufficient, if Sun Jianjun is allowed to find out the truth, then the other party will attack the city unscrupulously.

In this way, when camping, Gao Shun deliberately built many more empty camp tents according to Guo Jia's instructions, and then when he ate at dusk, Gao Shun deliberately set up more camp stoves. According to the analysis of the number of tents in Cao's camp and the cooking smoke reported from the scouts, Zhou Yu and Sun Jian felt that the number of support troops was at least 40,000.

————————————————————————————————

In Sun Jianjun's camp, Zhou Yu looked solemn and was thinking about some questions.

"Gong Jin, you say, why didn't Cao Cao's reinforcements enter the city?" Sun Jian sat on the main seat and asked Zhou Yu, his expression was also very serious.

"Cao Mengde is deceitful, maybe this is his strategy." Zhou Yu is also very puzzled by this, it stands to reason that when the reinforcements arrive, they should go into the city to help the defenders defend, but why did this support army camp outside the city?

After thinking about it, Zhou Yu thought that he had come up with a correct answer.

"I'm afraid Cao Cao wants to contain our army." Zhou Yu slowly said what he thought in his heart, "Cao Cao chose to camp outside the city instead of entering the city, probably because he wanted to attack when our army was attacking the city, so that our army could not take care of each other, and its momentum collapsed by itself." ”

In Cao Ying, Cao Zishuai's flag was hung high, so both Zhou Yu and Sun Jian thought that Cao Cao had come in person.

After all, it is an army of 40,000, no matter what unknown changes have happened in Guandu in the north, but since so many people have returned, it means that the war in Guandu must have come to an end.

Therefore, Cao Cao must be in the midst of reinforcements, and as his commander, Sun Jian and Zhou Yu are convinced of this.

If Gao Shun knew what Zhou Yu and they thought, he would definitely roll on the ground and laugh.

However, now Zhou Yu and Sun Jian are really embarrassed.

"As soon as we attack the city, they attack, so aren't we passive to the extreme?" Sun Jian's brows furrowed heavily, and he said in a deep voice.

Zhou Yu didn't speak, Cao Cao's 40,000 army arrived, and his army was indeed very passive now.

Sun Ce, Tai Shici, Zhou Tai and others on the side looked at Zhou Yu, who was speechless, and they were secretly anxious in their hearts.

Even Zhou Yu was silent, which showed the level of trouble in the situation.

"What is there to hesitate about? If you are afraid that Cao army will stab us in the back, then we can get rid of them all before attacking the city. Zhou Tai's personality is the most arrogant, and he muttered directly.

Sun Ce and Tai Shici heard it on the side, it was called a violent sweat, 40,000 Cao army, although in terms of the number of our army, it is still a little more, but if we really fight, our army may not be able to take the other party. Besides, since you said that the reinforcements may attack during the siege, why don't you want to think about it, when we attack the reinforcements, won't the defenders in the city still come and copy our back route?

We martial artists can think of this truth, but unexpectedly, there are people who are more stupid and naïve than us.

Zhou Yu roughly explained the truth to Zhou Tai, and Zhou Tai laughed a few times, and then fell silent.

According to Zhou Yu's original intention now, he wanted to persuade Sun Jian to withdraw his troops. After all, if Cao Cao really led the army back in person, then Xuchang City would no longer have any possibility of being conquered by the army.

But in the end, he didn't say the words of persuasion, he knew that Sun Jian would definitely not be willing to withdraw his troops.

As long as he can enter Xuchang City, then Sun Jian will really have the capital to win the world.

And if Sun Jian wants to win the world, he must also enter this Xuchang City.

Sitting in Jiangdong, no matter how well Jiangdong is developed, it is just a prince after all. Only by mastering the Son of Heaven and connecting Jiangdong and the Central Plains can we have the strength to expand to the whole world.

During the day, the self-army was only one line away from taking Xuchang City, if it was to increase its efforts, perhaps Sun Jian would have already entered Xuchang City by now and "greeted" the emperor.

What a pity!

Cao Ren, it was because of Cao Ren's sworn resistance that all this came to naught.

Now Zhou Yu regrets a little, when he took the East Gate as his goal, he was a little casual. If he had known that Cao Ren was so difficult, he should have investigated it well and chosen a city gate with such excellent guarding ability to implement the strategy.

But in fact, there is no regret medicine, things have evolved to this field, and now it is necessary to consider how to deal with the current situation.

Sun Jian, Sun Ce, Zhou Tai, and Tai Shi Ci all set their eyes on Zhou Yu, expecting him to come up with some good strategy to defeat Cao's army and capture Xuchang in one fell swoop.

If Zhou Yu knew that they expected so much from themselves, I am afraid they could only smile bitterly, I am just Zhou Yu and Zhou Gongjin, not some heavenly immortal.

Although Zhou Yu came up with some strategies, he was soon vetoed by himself.

In his opinion, since Cao Cao is in the reinforcements, there must be a lot of talented people around him, and the strategies he came up with before are not without flaws, and he may be seen through by a wise man.

If Zhou Yu knew that there was only one Gao Shun among the reinforcements, and there was no strategist to assist him, then he would definitely pat his thigh while hurriedly letting people carry out the strategies he had thought of earlier.

"Let's wait and see what happens." After a long time, Zhou Yu said such a sentence that disappointed everyone present slightly.

But no one will blame Zhou Yu, because they all know that Zhou Yu has done his best.
