Bian Bing raised his head in surprise. He didn't expect Xiahou Dun to ask him like this.

Xiahou Dun let out a breath, looked up at the smoke exhaled from his mouth dissipated in the air, "It is not difficult to conquer Shexian County, but the difficulty lies in the follow-up... Not to mention Shangdang, there are thousands of soldiers in Taiyuan, plus the northern territory protection of Taiyuan... If you fight steadily, even if you can fight, it will be difficult to achieve full strength without three to five years of hard work... But at this time...

"There is a general's plan..." Bian Bing subconsciously said some clichés, but was interrupted by Xiahou Dun.

Xiahou Dun turned his head to look at Bian Bing, "You and I are all close to the lord. There is no need to say more about these polite words. If you say too much, you will become more distant... You should also know that we marched into Shangdang, Taiyuan, just to restrain the strength of the cavalry and horses. If even the local defenders of Shangdang Taiyuan cannot shake it, how can we mobilize the three auxiliary personnel of the cavalry and create opportunities for the lord?"

Bian Bing was silent for a moment, "I understand. Then I will send someone to urge the soldiers to speed up and take Shexian as soon as possible!"

Xiahou Dun nodded, then turned to look at Shexian.

Below Shexian in the distance, there is a gray and black line that is not very obvious...

That was the newly dug trench.

...

...

Above the county.

Yan Zhi stared at the trench that was getting closer and closer under the city.

It is not easy to dig trenches in the cold weather, but the dug trenches are not easy to collapse. In addition, Cao's army almost kept digging, so the trenches were very close and were about to connect to the moat.

There is Zhang River next to Shexian, so there is also a moat. However, because the water level is lower, the water level of Shexian moat is also relatively low. As long as you are slightly guided away, the moat in Shexian, which is blocked from the water inlet of the upstream, will quickly dry up.

Liang Qi was on the side, "What should I do? It's broken! It's broken!"

"This is the technique of clashing the acupoint..." Yan Zhi swallowed his saliva. It was cold and the ground was frozen. Before it was frozen, the moat was no less than a powerful weapon. Even if he was not injured, he would just soak in water. After Cao's army returned, he would have to keep it for a few days, otherwise the infection of wind and cold would be infected with two, and a large area would be in a blink of an eye.

However, once the moat is empty, Cao's army is equivalent to being able to enter the city very conveniently. At that time, the city defense must remind Cao's army to attack at all times...

『Sneak attack... no, night attack...』 Yan Zhi said in a deep voice, 『Now there is only one way... night attack!"

Liang Qi looked at the trench under the city, "What? Night attack? How to break this trench?"

『Who said he wanted to break this trench?』 Yan Zhi said, 『It was the dam that blocked water upstream!』

As long as water is poured in at the source, even if Cao's army digs a trench, the water will be shallower. Moreover, if Cao's army wants to build a dam, it will take another time. The longer the delay is, the more the Cao's army suffers in the wild...

So, it is still necessary to attack at night.

But today's attack is different from the past.

Yan Zhi was able to understand the importance of blocking dams upstream. Doesn’t Xiahou Dun understand?

In addition, the importance of several night attacks demonstrated by Fei Qian's potential wars in the northern and southern battles, how could there be a reason for Cao Cao, a military master?

Although there is no way to strengthen the logistics supply of the entire army like Fei Qian, it is still possible to strengthen nutrition for the private armies of important generals and improve their visual ability at night. Therefore, at present, Fei Qian's official report in the martial arts lecture hall indicated that night attacks are not a panacea, and also reminded all military generals that as long as they are well prepared, the night attack will actually suffer even more...

But now, there seems to be no other way, or Yan Zhi and Liang Qi have not been able to come up with any better way. If the intercepted dam cannot be destroyed, then you can only sit and watch Cao's army drain the water from the moat, which is undoubtedly a more dangerous and difficult thing.

...

...

The night has sunken.

The mountain wind is gradually rising.

In the sky like ink, there were a few stars shining listlessly. The harsh winter was approaching, and the birds and insects in the mountains were silent, and everything was silent. Everything was shrouded in the boundless darkness.

Yan Zhi and his men quietly, under the cover of night, lowered the rope down the city wall and touched the upstream dam to the intercepting place.

There is still no movement or movement in the dam or surrounding areas.

Only when approaching Cao Jun's camp was the light of some vaguely jumping bonfires, and some figures were shaking.

Yan Zhi held the sword, quietly bent over and walked forward.

He suddenly felt a little regretful.

He was more familiar with cavalry. He liked the prairie. His battlefield should be on the grassland and desert. It was just that he hated fighting on the grassland, so he arrived in the mainland. However, he didn't expect that the war could not be avoided. Even if he arrived in the mainland, he still came to the mainland. If he had known this before, it would be better to stay in the Northern Territory before, so that his brother would have to accompany him to the mainland.

In fact, the grassland is where they adapt more.

I don’t know why his brother came to help so slowly this time. Logically speaking, he should have arrived now...

Two hundred steps.

With the faint light of the stars, you can see the black dam.

The river dam blocking entrance was temporarily erected, so the branches and branches were scattered in the night.

There was no sign of Cao Jun at the blockage.

It seems normal, after all, the cold wind is howling, so who would like to be blown by the wind in the wilderness?

One hundred and fifty steps.

Yan Zhi felt that his breath became heavy, and even the breathing of the people behind him was also heavy. He held the sword tighter. He seemed to pick up something in his mind and warned him, but he didn't pay attention. He was just thinking about one thing in his mind, rushing over, rushing to the intercepting dam, killing all enemies who dared to resist, and then returning to the city!

One hundred steps.

Yan Zhi stared at the front and stepped over several branches and leaves that seemed to be thrown away on the ground. The dam blocking entrance was already close, and there was still no figure of Cao Jun...

Suddenly, a crisp copper ringtone rang in the night!

Yan Zhi suddenly turned around and saw that his subordinates not far away seemed to have encountered something, causing the sound of the bronze bell to ring in the night!

His heart suddenly tightened!

Before Yan Zhi could react, someone shouted in the darkness: "Cum!"

The sharp whistling sound came towards us!

Almost at the same time, some torches were lit, and then they threw a high arc and fell to Yan Zhi and others. On the opposite side of the fire, Cao's figure swayed, and short commands rang one after another...

Oh no!

There is an ambush!
Chapter completed!
