When Zhao Yun led the green dragon to ride across the Langdang Canal, he was in Yuzhou, a little south. The war between Cao Cao and Liu Biao also reached a critical juncture.

At the beginning, Xu Huang, the commander-in-chief of the three armies in Yuzhou, was defeated and retreated under Liu Biao's surprise attack. Although Cao's army did not lose much, the city lost a lot. Gradually, the pace of war retreated to the city of Runan again. As it stands, it seems to be a replica of the war nine years ago.

That year, under the city of Runan, too many stories happened. And today, the defensive front of Cao's army still came to the city of Runan.

This time, with the lessons of nine years ago, it is impossible for Xu Huang to make the mistakes of the year again. Therefore, the battle of Yuzhou once fell into a stalemate. Liu Biao's army launched an attack day and night, while Xu Huang firmly used the city wall for defense. You come to attack, I will defend, this is naturally the right way, but if you let me go out of the city to attack, I'm sorry, I won't go out. Even if you put Cai Mao's head on my Xu Huang's table, I won't go out.

Cao Jun's rogue defense this time really gave Cai Mao a headache. Oil and salt don't enter, soft and hard don't eat, so Cai Mao has no other way than to attack.

When Cao De's reinforcements and the Tianxiang army led by Cao Ren arrived near Runan City, Xu Huang and Cai Mao were stumbling. After Cao Ren sent out the sentry cavalry, he immediately made adjustments according to the first news he received.

The 10,000 men of the Tianxiang Army's infantry battalion immediately circled Cai Mao's rear, while the 10,000 men of the Tianxiang Army's cavalry battalion immediately drove to the vicinity of Runan City.

When Cai Mao found the army appearing on his side, Cai Mao realized that his situation seemed to be very bad. However, what Cai Mao guessed was not good was not the same thing as the bad thing that Cao Ren was about to give him.

"Quick, go and find out immediately how many people are coming from Cao De's army!"

"General, 10,000 people, just a little more!"

The size of the cavalry of 10,000 people does not need to be deliberately counted at all, and experienced generals only need to look at it with a big eye to guess the same.

And Cai Mao was scared at the answer of 10,000 people. Cai Mao knows very well that Cao De either doesn't move, as long as there is action, it must be a vigorous and resolute action. And with only 10,000 people like today, that's impossible. Therefore, Cai Mao came to a conclusion that it is definitely not as simple as 10,000 people around him. There must still be an unknown number of large armies already lying in ambush on their way to retreat. As long as you mess up, you're doomed. Therefore, Cai Mao immediately ordered, "The whole army maintains a formation and retreats slowly." ”

As long as the Cao army on the opposite side does not attack, then we will not provoke them. Everything will be said when he retreats to the city. Since Xu Huang and Cai Mao have been playing defensive battles for so long, why can't Cai Mao play with the combination of Cao De and Xu Huang to resist the city once. Anyway, we have a lot of infantry, and the cavalry can't be directly engaged in siege warfare. So, let's drag it out.

Cai Mao's consideration is actually very normal.

Defense, since it is to be set as defense, it must be to defeat the enemy at the minimum cost. There are many types of defense, and although the use of city defense is the most passive defense, this type of defense is common and a way to reduce your own losses.

Cai Mao was slowly retreating, and Xu Huang in the city could see it clearly. Xu Huang couldn't help but feel a burst of curiosity, why are you fighting so passionately, why are you suddenly ready to leave. Do you want to retreat as a preparation to pit me! Therefore, Xu Huang soon ordered: "No pursuit!" ”

How do you like to play, Lao Tzu just won't play with you.

And when Cai Mao's army became thinner and thinner, Xu Huang, who was standing on the city wall, finally saw the army staring at the low hill on Cai Mao's side.

Who's that? When did we have such a large army on our side? Could it be Cai Mao's reinforcements? If it really is, Cai Mao has come with reinforcements, why is he still retreating? This is even more bizarre. If you talk about reinforcements, I haven't received a report from the back that the King of Wei is going to send reinforcements. Could this be Cai Mao's trick for me?

After the big defeat nine years ago, Xu Huang is now very careful. Why? Just because Cai Mao is a stupid person. If you treat Cai Mao as a fool, maybe Cai Mao and Jing Yue will have a big reversal at any time, just like nine years ago, and if you look at Cai Mao, these battles made by Cai Mao are really not good. So, to be on the safe side, let's keep it guarded. Don't ask for reactive power, but ask for no fault, this is always okay!

Cai Mao's army had gone farther and farther, not only Xu Huang in the city was indifferent, but even the unknown army standing on the low hill was quietly saluting Cai Mao.

Finally, when Cai Mao was gone, they moved! Slowly move towards Runan City. This time, Xu Huang's nerves suddenly tensed up again. Why did you just leave a batch and come again, could it be said that you can't fight the wheels at this time?

"General, the situation is not right. The clothes that the gang were wearing didn't seem to be Liu Biaojun's blue clothes, but red battle clothes! ”

"Red suits?"

Under the light of the setting sun, everything on the earth is showing a golden color, coupled with the light reflected by the armor, it is really not easy to tell what color the suit is.

Gradually, the army on the opposite side got closer and closer. "General, it's a red suit. The subordinates saw it clearly. "At this time, there is no need for him to talk nonsense, because Xu Huang can also see it clearly." The red battle suit, and the big flag, this, this is Cao Gong's army! ”

Xu Huang suddenly figured it out, where is Cai Mao's reinforcements, but our reinforcements. Our rear party is not only King Wei, but also Prime Minister Cao Cheng!

"Quick, open the city gate and welcome the army of Cao Gong into the city!" With reinforcements, Xu Huang was naturally happy. But......

"The general is slow, if it is really Cao Gong's army, then why didn't he attack Cai Mao, but quietly watched Cai Mao escape. According to the subordinates, this must be the disguise of Cai Mao! ”

"You mean, at this time, Cai Mao's people pretended to be Cao Gong's army?" Xu Huang said in surprise. Soldiers, treacherous! There is often only one chance, and defeat is defeat, and it is impossible to have such a good thing as regretting chess. Therefore, Xu Huang must not be cautious.

"Then be on guard. Wait until I've found out, and then I'll act! ”

"No!"

It's still the same sentence, if you're not afraid of 10,000, you're afraid of what happens, it's better to be careful.

But when the person in the lead approached, Xu Huang couldn't help but give the person behind him a big mouthful.

"Xu Huang, what are you kid doing. Lao Tzu came to help you, did you actually take a bow and arrow to greet Lao Tzu? ”

"It's General Cao Ren, the army is fake, is General Cao Ren still fake? You kid killed me, go and open the city gate, and General Ben will personally go down to the city to greet you! ”
