Sun CE always comes and goes straight, and rarely goes around in circles. Although sun CE's temperament is like this, he has never been willful on the battlefield. He knows that the temporary retreat is not fear, but for better counterattack.

So sun CE listened to Lu Su's suggestion, but he didn't make a decision immediately. Instead, he looked at Zhou Yu and said, "Gongjin, how do you know that Zhang Xiu sent troops?"

Today, Zhou Yu is also much more mature, he said: "Your Highness, I agree with Zijing's proposal. The killing of Zhang Xiu's army is a great threat to the state of Wu. If we are short of troops and fight head-on, we will be defeated. "

"It's a fool's job to attack the other with his own short points."

"So now, we will go back to Chaisang. On the one hand, there is the Yangtze River to the north of Chaisang. We can use the advantage of geographical location to block Zhang Xiu's army. On the other hand, it's also an opportunity to let Zhang Xiu know that it's easy for him to gallop in the north, but when he comes to the south, especially in the south of the Yangtze River, his army has to shrink. "

Zhou Yu gave suggestions.

Sun CE said: "if so, withdraw immediately."

Zhou Yu said, "Your Highness is wise!"

Sun CE is not a procrastinator. He does things in a crisp and resolute manner. After working out a plan with Zhou Yu and Lu Su, he moves quickly. Sun CE, who was attacking Jiangxia County, withdraws his troops and leaves.

This news first spread to Huang Zhonger.

After Huang Zhong got the news, first, he arranged for people to send the news to the rear and let Zhang Xiu deal with it; second, he strengthened the arrangement of sentries and arranged more sentries to inquire about sun CE's news, so as to ensure that he knew sun CE's situation in time; third, he slowed down the speed of going on the road slightly and was on guard to avoid being ambushed.

Huang Zhong doesn't know whether sun CE's retreat is a real one or a fake one. If he is ambushed in front of him and is killed by sun CE, it won't be wonderful.

So along the way, Huang Zhong went on cautiously to ensure the steady progress.

When Huang Zhong arrived at the border of Jiangxia County, the news spread to Zhang Xiu in the rear.

Zhang Xiu saw sun CE withdraw some, some accident.

Sun CE came, but even if he withdrew.

Obviously, she doesn't want to fight him head-on, but if Zhang Xiu withdraws with the army now, sun CE will invade Jiangxia county again. This is a typical way for the enemy to advance and retreat. Zhang Xiu knows it very well.

In such a situation, the only way is to make the opponent's strength incomplete and unable to organize the offensive.

Otherwise, the other side is like a dog skin plaster, sticking up constantly.

It's disgusting.

If Zhang Xiu wants to go north to deal with Cao Cao or Yuan Shao, the first thing to do is to defeat sun CE's army and make sure that sun CE can't send any more troops in a short time. Therefore, in Jingzhou, Zhang Xiu doesn't have to worry and can go north with all her strength.

Zhang Xiu and his army continued to advance to the front line. When Zhang Xiu's army came to the border to join Huang Zhong, the army was temporarily stationed and did not continue to advance.

The Chinese army is in the tent.

Zhang Xiu sat down with all the guests and guests. Looking around, Zhang Xiu said in a deep voice, "about the battle with sun CE's army, sun CE has retreated to Chaisang county and settled down in Chaisang county. What do you think of it?"

Zhang Song sat down and didn't yell.

He was used to it.

Every time he opens his mouth, he will be rejected immediately. In the end, his suggestions are not smooth. So when Zhang Song hears Zhang Xiu's inquiry, he thinks carefully in his heart. At the same time, he also waits to see what Jia Xu and Sima Yi have to say.

However, neither Sima Yi nor Jia Xu took the lead.

Seems to be thinking.

When Zhang Song saw this, he couldn't restrain his agitation and said, "Your Highness, I think the main problem of attacking Jiangdong is to cross the river. This is sun CE's defense focus and the place where he attacks us."

Zhang Xiu nodded, a look of listening and encouragement.

Inspired by this, Zhang Song said, "under the current situation, what sun CE relies on is the Yangtze River. In fact, Jingzhou has always had a water army. That's why I think we can transfer the water army of Jingzhou to cross the Yangtze River. As long as we cross the Yangtze River, we can drive straight in and get firewood. "

Sima Yi said: "the question is, once we cross the river, will there be Wu state building boats on the Yangtze River to attack? You know, what Wu is good at is fighting on water. "

"If we go to World War I, we may not be able to stop it."

"The most important thing is that all the soldiers in our army, except the Feixiong army, are not used to water fighting and let them fight on the ship. They are shaky and unstable, and even feel uncomfortable. I'm afraid it's difficult to fight."

Sima Yi said: "the Yangtze River is vast and broad. Even in the cold winter, people who are not idle can not spend it in the dry season."

Zhang Song said: "to defeat sun CE, that's a step we must take. Even if it's hard, I'm afraid it's easy to deal with. Your highness, there is a way to ensure that the soldiers in our army will not be affected by the waves of the ship and can fight like walking on the ground. "Zhang Xiu said, "what's the plan?"

Zhang Song replied: "our army of 80000 and 90000 has countless soldiers. If we want to cross the Yangtze River, we must recruit countless warships and building ships. We can connect all the warships with iron locks. If such a building ship is connected in series, there will be less shaking and swinging. In this way, we will not be afraid even if we are attacked."

Zhang Xiu began to laugh.

Isn't that the result of Cao Cao's defeat in Chibi?

This era is not like later generations. It's very easy or even comfortable to cross the Yangtze River. However, in this era, both sides of the Yangtze River have not been developed. Only the ferry terminal can log in, so it's very difficult for northerners to cross the Yangtze River.

It's extremely vulnerable.

But the problem is that there are also considerable problems in connecting building ships and warships.

When Sima Yi heard Zhang Song's words, she thought about the feasibility of Zhang Song's plan.

But Jia Xu stroked his beard and said, "Lord Zhang, all our building ships are connected by iron locks. But in case sun CE's army takes fire attack and rushes into our building ship with countless ships carrying hay, how should we deal with it when all the building ships catch fire?"

Brush!

Zhang Song's face changed greatly.

He didn't take this into consideration. It was a complete omission.

If this really happens, it will be a loss of troops and a loss of generals in the end. Even if the 80000 troops can't even touch the other side's hair, they will have to go back to their homes and lose. There will be countless obstacles to the unification of the Qin Dynasty.

This battle against sun CE is of vital importance.

Zhang Xiu won sun CE's battle, and it's easy to wipe out Cao Wei. If we don't win sun CE, Qin's strength will be damaged. If we want to unify the world, it will be impossible in a short time.

So it has to be won.

Zhang song took a deep breath, suppressed the bitterness of his inner breath, and said, "Jia Shangshu refuted my strategy. Then, what brilliant strategy does Jia Shangshu have to let his Majesty's army directly enter the state of Wu and win this war?"

He began to fight back.

This attack on Sun CE was different from the fighting in the north. The fighting in the North was mainly the fighting of cavalry and infantry, but the developed water system in the South was not suitable for the fighting of cavalry.
