August 13th, night.

Although the moon is not full, the moon is bright and the moon shines on the ground extremely bright.

The fires of the Wei army camp on the south bank of the Zhang River were swaying, and Sima Yi was wrapped in a fine velvet wool blanket and stood on the high side of the river embankment, like a piece of dead wood standing on the shore.

The autumn gradually rises, especially at night, it is already a little chill.

Sima Yi has been working hard all night and often overworked.

If I hadn't been relying on my heart to hold on, my body would have collapsed long ago.

Even though the chill was not heavy, Sima Yi, who was getting more and more hunched, could no longer bear it. He had to grab both sides of the blanket and wrap himself thicker.

The dull sound of rammed earth came not far away.

Five thousand Wei army engineers stepped barefoot in the cold river mud, digging the embankment with the ignition torches and moonlight.

The friction between shovels and earth and rocks mixed into the sound of water, as if a giant beast was grinding its teeth in the dark.

Guo Huai rode his horse and rushed over, his battle robe covered in mud, and he whispered:

"Tao Fu, Sanhujin, is ready."

Sima Yi nodded, leaned over and grabbed a handful of wet river mud, and said slowly:

"When Emperor Wu built a Tongquetai in Yecheng, the Zhang River became a natural danger. Now I also want to use this water force to block the Han army..."

In order to capture Yecheng, Emperor Wu once destroyed the Zhang River to flood Yecheng.

Now, in order to stop the pursuers behind, I can only dig out the Zhang River...

At this time, a low voice came from the underworld.

It turned out that someone's hoe suddenly broke and the hoe blade was stuck on the oak pile deep in the embankment.

This wooden stake was built by Cao Cao when he built the Zhangshui embankment around Yecheng.

Twenty engineers wrapped around wooden stakes with hemp ropes, and the sound of the horn suppressed the rhythm of the water: "Hey—Yo!"

When the solid wooden stakes slums slumped, the first turbid current was like a black snake coming out of the hole.

"retreat!"

Mud sprayed out of the gap, and the ceramic guide pipe buried in the early years was destroyed, the gap was constantly torn, and the mud gradually turned into mud and water...

Seeing all this through the moonlight and firelight, Sima Yi ordered Guo Huai:

"Go, light a wolf smoke and send a message to Sanhu Tsu."

"Here!"

As the gap continued to expand, the Zhang River gushed out. Coupled with the canal built by Cao Cao in his early years, the south bank of the Zhang River quickly became a Zeguo.

At dawn, the flood had formed mud of varying depths within a radius of dozens of miles - the shallowest part could reach the horse's leg joint.

The flood wrapped the humus soil upstream, dyeing the fertile fields on the south bank of the Zhang River into ochre.

The locust trees that the Wei army cut down in advance became a natural embankment, and the branches were covered with baskets of fleeing people.

Seeing this scene, Sima Yi's mouth finally loosened, and he pointed at the field mouse struggling in the mud:

"The cavalry is like this at this point. Feng Thief, Feng Thief, let me see, why are you here to chase me?"

Looking up at Yecheng in the east, a cold light was jumping in Sima Yi's eyes:

"When Emperor Wu attacked Yecheng in the past, he used water instead of troops, and today I will use mud as a formation."

He suddenly raised his foot and crushed a crawling mole cricket, "Tell me the order to pull up all the gates of Yecheng and lead the water from Xuanwu Pond to the south. I want to keep this Nize for a month!"

Since Zhang Bao was in Liangqijin, the Han army on Yecheng was just suspicious of the troops, and it was not to be afraid.

Anyway, if he can't defend Yecheng, he will turn the south bank of the Zhang River into a giant mouth of Taotie that devours the Iron Cavalry at the cost of this thousand miles of fertile land.

Instead of letting Feng thief lead Zhangshui to attack Yecheng, it is better to do it yourself.

When the morning light tore open the mist of the Zhang River, the Zhangba Snake Spear pierced into the soil on the north bank of the Zhang River.

Zhang Bao held up his telescope and looked at the dark brown mud on the other side, and his pupils suddenly contracted.

The south bank, which was still as flat as a raging beast, was now like a rotten corpse gnawed by giant beasts. Half a piece of locust tree branches floated in the surging mud, and the branches were hanging on the branches of children's shoes left by the people when they fled.

"Old thief Sima!"

Zhang Bao's face turned ashen, and he couldn't help but shout, drawing his sword to the willow tree on the shore!

"brute!"

"Beast!"

Last night, I knew there was something going on on the other side, and even lit a smoke. I thought it was Sima Yi who was going to make some tricks on the North Bank.

Zhang Bao secretly asked the soldiers in the army to be prepared.

Unexpectedly, the other party was digging a dike!

He found that he still far underestimated Sima Yi's lower limit.

“Try the road with a board!”

Because the Zhang River continues to flood the south, the Wei army has taken the initiative to retreat.

He barely wades through the Zhangshui River, which only reaches his calves, and arrives at the south bank. The guards carry the wooden boards on the mud, but the wooden boards sink at a speed visible to the naked eye.

Zhang Bao didn't believe in evil, so he rode his horse onto a floating board. After walking three steps in the war, the mud and water fell to half of his leg.

The beast roared in horror and overturned the wooden boards while struggling.

Fortunately, Zhang Bao's horseback riding was good. He turned over and got off the horse and returned to the safe place. He bent over and grabbed the black mud and crushed it. The mud dripped from his fingers, and a low growl burst out between his teeth:

"What a vicious plan, what a cruel heart!"

He knew the most about how fertile the fields around the Zhang River were.

Otherwise, Cao Cao would not have promoted water conservancy around the Zhang River and diverted the twelve channels of Zhang River to use them for farming.

In order to stop the pursuers, Sima Yi actually turned these fertile fields into a marsh country.

The other party's purpose is very obvious, but Zhang Bao had no choice at this time when facing this situation.

"General! There is a situation in the east..."

The news came from Sanho Tsu as quickly as possible:

"The thief army, the thief army is at night..."

After finishing the conversation, I saw the scene in front of me and was choked:

"Sanou Tsuyi became a Zeguo..."

Zhang Bao stood there in a steady state without saying anything.

No need to think about it, Yechengjin will be similar.

He quietly led his troops back to Liangqijin, caught Sima Yi off guard, and forced the other party to break his tail.

I thought it would be avenge a revenge for the ambush, but I didn't expect Sima Yi to immediately repay him overnight.

At this moment, he finally felt a deep sense of powerlessness.

How did your brother-in-law chase the opponent away?

It was not until the scorching sun at noon that the mud was covered with cracked fine lines, and Zhang Bao's head was soaked with sweat.

He simply tore it off and threw it into the quagmire, rolled over the horse again, and wanted to try again without giving up.

The horse's hooves shattered the thin ice-like mud shell, and the horse's legs quickly fell into the mud pool - there was still a sludge trap under the surface hard shell.

More importantly, the Zhang River continues to flow, so it is difficult for this Zeguo to disappear.

Backing back to the north bank, Zhang Bao sat dejectedly under the broken willows, staring blankly at the Zeguo in front of him.

Judging from the current news, Liang Qijin to Yechengjin - perhaps even going east - may have to be at least seventy miles, and they may have become a quagmire that cannot be walked in a short period of time.

Even if his brother-in-law came at this time, he had no way to continue to go south to pursue Sima Yi, so he could only watch the other party retreat calmly.

While my thoughts were rolling, I heard a report in my ears:

"Report! General, there is something happening in the north!"

"Oh? Yecheng isn't already..." Before he finished speaking, Zhang Bao finally felt something was wrong and almost jumped up. "North? What's going on in the north?"

"General, news came from the north that he had met our people."

"Our people?"

When Zhang Bao heard this, he didn't quite understand.

Who else can I have in the north besides my brother-in-law?

But if you really are brother-in-law, then Chuanqi should be saying "Grand Sima" rather than "our people".

"It's General Zhao! It's said that General Zhao is coming here."

"Zhao Sanqian?"
