With Liu Zhengjin's investigation, these news quickly reached Liu Zheng's ears.

His Jinyi guard really saw that there were some people on the landscape near Gaotang Lake, who were sneakily digging something.

Although the work is done secretly, if you want to dig the dam of Gaotang Lake, you need to use a lot of labor, and the movement cannot be small, as long as Liu Zheng's men and horses pay a little attention, they can be detected.

When the news reached Liu Zheng's ears, two more days had passed.

The water level of the Huai River has risen again, although it has not reached the point of directly flooding Huainan City, but time is a little more urgent for Liu Zheng.

"Lord, it's a big deal, those people are really digging a dam, and it is very likely that they will dig up the water of Gaotang Lake and divert the flood water to directly irrigate Huainan City!"

Xu Huang, who received the news, looked nervous and rushed to Liu Zheng to report the news.

Although Xu Huang reported the news to him, Liu Zheng was not surprised at all at this time, as if he had already guessed it.

"Yes, if Liu Bei is not stupid, he will definitely not give up the opportunity to flood Huainan City, and we will be a little embarrassed at this time."

Liu Bei was not in a hurry to attack the city, but wanted to wait for the water level to rise, and then use the water of the Huai River to flood Huainan.

Liu Zheng really didn't expect this time that the Huai River was rising recently, and the soldiers and horses he brought over were all cavalry under Xu Huang.

The cavalry originally planned to attack the city with Liu Bei's full strength, and after being exhausted, they suddenly killed Liu Bei's people and attacked them with all their might, but now they didn't expect that Liu Bei would not attack.

"Lord, what shall we do now?"

"What else can I do, of course I have to leave, continue to stay here, isn't it just waiting to be flooded by them, they have surrounded three city walls, there will be nothing to do here by the river, I have asked Zulang's army to rush over to support two days ago."

"Later, we will take advantage of Liu Bei's people and horses, and we have not yet implemented the plan to flood Huainan, so we will give Liu Bei a dismount first."

"How's the plan?"

"I will lead 20,000 people to break through with Wen Ping, I guess they will deliberately let me break through, and then annihilate our army in the field, but at this time, you lead 20,000 cavalry to kill from behind and severely demolish Liu Bei's morale, how about it?"

Since Liu Bei plans to flood Huainan City, Liu Zheng naturally can't sit here and wait for Liu Bei to flood Huainan, Liu Zheng naturally has to make some changes.

This time, Xu Huang became interested, he didn't have any plans in this city these days, and he was a little impatient, and now Liu Zheng finally had the intention of fighting with Liu Bei, where would Xu Huang refuse.

"Lord, you can give the order, these cavalry under my command will finally come in handy, raise soldiers for a few years, it's time to make contributions to the lord!"

Xu Huang's mood was high, which made Liu Zheng also see some hope.

"Okay, without further ado, immediately let Wen Ping lead the people guarding the city to come over, we plan to break through from the south gate, the south gate is the place where Liu Bei's people deliberately show weakness, they are actually waiting, waiting for us to break through. We'll do what we count. ”

Although Liu Bei surrounded the entire Huainan City, Liu Bei, who had only 70,000 soldiers and horses, put 30,000 Chen soldiers in the west, 30,000 Chen soldiers in the north, and only 10,000 in the south.

This meaning is obvious, if Liu Zheng breaks through, then the only choice is to choose the south.

In fact, Liu Bei also wished that Liu Zheng would break through, because Liu Zheng did not have many troops in Hehuainan City, and once he broke through Liu Bei, he was still sure that Liu Zheng could be killed outside the city.

During the siege war, Liu Bei's people were at a disadvantage, but in the field of encounters, Liu Bei's people had an advantage, whether it was the advantage in troops or the advantage in individual combat power, it was obvious.

So Liu Bei only waited for Liu Zheng to break through.

It just so happened that Liu Zheng could also understand Liu Bei's thoughts, and at this time, he simply planned and gave it a go.

Soon, under Liu Zheng's instructions, the personnel on the city tower began to decrease, and the people in the city, Liu Zheng led the soldiers and horses under Wen Ping, and stationed them at the south city gate.

"Open the city gate, let's kill it, remember to be ready to withdraw to the city at any time, give Liu Bei and these people a false impression, thinking that we are going to raid!"

"Yes, my lord!"

Wen Ping waved his hand at the soldiers who controlled the city gate around him and signaled to open the city gate.

Then the city gate was slowly opened, and Liu Zhengjun inside, under the leadership of Wen Ping, began to rush out of Huainan City.

Liu Bei's garrison outside the city was still a little leisurely, but he didn't think that Liu Zheng's people would go out of the city at this time, but at the moment when the city gate moved, these people outside the city immediately blew the horn.

At this time, the sound of whining immediately made Liu Beijun's men nervous.

"The enemy is out of town!"

I don't know who shouted, and the soldiers guarding the south city gate by Zhang Fei immediately stood up at this moment and began to surround the city gate.

Wenpin's men did not hesitate at all, and when Wenpin opened the city gate, he took the lead in rushing towards the place with the most people, the purpose was to break through to the outside of the city.

Zhang Fei glanced at the enemy who rushed over, shook his hand, directly took his Zhangba snake spear in his hand, and shouted at his side.

"I really let the eldest brother calculate, these people of Liu Zheng will actually break through at this city gate, soldiers, we can't let Liu Zheng's men and horses escape from us! Follow me up to block the enemy, and the eldest brother's people will come in a short time! ”

After Zhang Fei shouted, he rushed forward in the lead, planning to lead by himself and go over to block Liu Zheng's breakthrough men and horses first.

Zhang Fei's strength is very strong, and the soldiers and horses arranged in this south are also very strong, and they are all the elite of Liu Bei's subordinates.

Although there are only 10,000 soldiers and horses arranged by Liu Bei at the city gate in the south, they are the most elite 10,000 people.

And at the first time, Gongsun Chan at the other city gate will be killed in a short time, Gongsun Chan has a part of the cavalry, which is Gongsun Zhan's most elite white horse servants, these white horse servants are light cavalry, and they can quickly support the southern city gate in a short time.

So although it seems that the south side is a good place to break out, in fact, it is heavily guarded, and if Liu Zheng's men and horses choose to break through in this place, unless Liu Zheng's troops are as many as Liu Bei's.

Otherwise, it will be extremely difficult to break through from here.

Wen Ping and Zhang Fei's soldiers and horses collided together at this time, and the two sides immediately fought fiercely, but they were not killed by Wen Ping, but let Zhang Fei's men and horses force themselves and block Wen Ping's attack.
