Five days later, the city of Changli.

It is obvious that in the past five days, the Han army has completely mastered the alluvial plain between the Dayu River and the Xiaoyu River. Except for the lonely Tuhe City at the southern end of the Dayu River, there is no trace of the rebels' sphere of influence.

There is nothing to elaborate on the military discussion process between Liu Bei, Li Su and Lu Su, because Li and Lu fully agreed with Guan Yu's suggestion - to encircle three missing one, to encircle the river and attack Changli, completely removing the main strongholds where the enemy still had food and grass accumulation.

In order to achieve this goal, while completely controlling the two rivers, there were two other Han troops, each with about 3,000 troops, crossing the Dayu River, and establishing camps on the east bank, besieging the north gate and the east gate of Changli City respectively.

The west gate of Changli City is next to the Dayu River, which is equivalent to using natural rivers as moats, so it is difficult to siege. However, when the Han army had the advantage of the navy, the rebels could not escape from the west gate.

As long as they surround the North Gate and the East Gate, they will leave the South Gate for the enemy to escape. When they really feel that they can't hold on, they will go to Tuhe from the South Gate, or expect the reinforcements from Tuhe to come from the South Gate to reinforce.

Zhou Tai was besieging the north gate of Changli, and Guan Yu was besieging the east gate.

Zhou Tai was responsible for attacking the city gate in front of him, so the pressure was less. Guan Yu had to take into account the necessary energy to prevent being attacked by enemy reinforcements, and the task was heavier.

Zhao Yun still had the same rules as the cavalry and was ready to intercept and kill at any time.

Zhang Fei honestly led 5,000 people, some defended the Han army's water village granary, and some besieged the two gates of Tuhe City, leaving the east gate, so that the enemy soldiers in Tuhe saw hope of returning to help.

The Han army's siege forces are actually slightly inferior to the number of defenders in the city.

But who made the Han army so arrogant? I have fewer people than you and dare to surround you. If you have the courage, you can go out of the city to fight. I am just looking for it!

Six thousand people surrounded 7,000, and five thousand people surrounded 6,000 and even guarded the village. The Hu people dared not attack the camp!

The death of King Nanqiao has given every Wuhuan general a blow: when the Han army had a crossbow formation, relying on light cavalry with only leather armor to attack the Han village is seeking death!

...

On the ninth day of the third month, sunny.

After the morning dew was evaporated by the sun, Li Su also followed Liu Bei to patrol the camp in the north of Changli City, preparing to usher in the first day of the siege.

The morning light shines on the river surface of the Dayu River and on the black soil on the other side. It gives off a vibrant artistic conception. You can see thousands of ploughed horses transferred from captured slightly injured horses, dragging plows, and plowing back and forth. Tens of thousands of farmers are busy irrigating and sowing seeds.

The river valley between the Dayu River and the Xiaoyu River was controlled by the Han army for less than a week, so I missed the best time to cultivate rice in spring.

However, the black soil between the two rivers is the most fertile, and it is the mature fields that people have cultivated in previous years. It was temporarily abandoned because of the war in the past two years. Now there are more and more refugees coming, so it is definitely not enough not to farm. So Liu Bei asked Lu Su to organize further expansion of the scope of military farming.

Cracking soybeans and vegetables in these areas, although they do not provide much food reserves for winter, can provide more seasonal rations in summer and autumn.

This is why the strange scene of "the east bank of the river is still fighting in the city, and the west bank of the river has begun to cultivate farms and reclamation", which also fully exerted the fearlessness and provocation of the Han army-

If the rebels dared to go out of the city and cross the river to massacre refugees, the Han army would send troops to intercept them and kill them, and they would definitely be able to tell them that they would never come back!

I believe that as long as I am not a murderer who would rather die than drag a few innocent people on his back, I will definitely not do such a crazy thing.

Lu Su wanted to farm the farm, and only Li Su, the military advisor, took on the job of being a staff officer in the battle.

At the end of the Mao hour, the soldiers in Zhoutai Camp had already finished cooking and started eating breakfast. After preparing for a meal, they rested for half an hour before they lined up to attack.

The breakfast time was advanced and was arranged in order to fight. Li Su also took a few words about it, and the interval between eating and fighting should be extended, at least half an hour, to reduce the incidence of appendicitis and reduce unnecessary non-combat attrition.

This kind of medical common sense is not very good for ordinary people in the Han Dynasty. If the military advisors take care of it, then just execute it.

Taking advantage of the soldiers' meals, Liu Bei and Li Su took more than a hundred cavalry to the north gate of Changli City, and patroled a circle a few hundred steps away from each other.

Then, according to the strategy set by Li Su the day before, Liu Bei divided up several sharpshooters who could draw strong bows. He led by Liu Dun, the commander of the Wuhuan Tuqi Tun, to more than 100 steps below the city, quickly raided the formation horizontally, and shot several arrows at the top of the city.

The rolled silk book was wrapped around the arrow shaft, which was about to persuade Yan Rou, the military advisor of King Nanqiao to surrender. He also said some vague words in it.

What "Su Zhi was captured by Wuhuan since childhood, and was born and raised by Hu Tan Feng, and his heart was really towards the Han Dynasty. If it were not for Zhang Chun, King Nanqiao would not have been solemn. If he surrendered as soon as possible, he would have to kill Nanlou, and he would have been able to leave the blame and grant him the position of the county, and would be rewarded with twenty kilograms of gold and two hundred pieces of silk."

The most vicious thing is that the letters were deliberately modified by Cao Cao. They also implied that "the reason why I know that the city's head is now a difficult place is because Yan Rou had informed us before and was already leaving a way out for herself."

If you want to distract yourself from books, it is not called a complete set!

As for the "Nanlou" mentioned in the letter, it is the nephew of King Nanqiao. King Nanqiao's son is still young this year and cannot control the tribes left by King Nanqiao after his death.

Therefore, after analyzing the personnel of the enemy's main generals and officers, Li Su thought that the main general who is still in charge of the Changli City is definitely difficult, and he had to write this way if he wanted to disagree.

"Can Yan Rou really kill Nanlou and surrender? If he surrenders, he really has to pardon him? He was the chief evil sent by Zhang Chun to talk about the anti-Nanqiao King. It can be said that the sin is still above the King of Nanqiao. Now he has killed the general whom he said was rebellious and left behind the instigator. Will he not be able to convince the public?"

After Liu Bei saw the arrows shooting up the city, he was still a little nervous.

The reason why they came to the North Gate to shoot today was that they learned in advance that the North Gate was the defense zone that Yan Rou was responsible for. The letter of shooting here would definitely fall into Yan Rou's hands.

As for whether Nanlou can be obtained, it depends on whether Nanlou has eyes and ears around Yan Rou, whether she is suspicious enough, and is willing to ask for trouble. If he has Ma Chao's courage, he will definitely dare to do this.

Faced with Liu Bei's concern, Li Su comforted:

"No matter whether Yan Rou has the opportunity to kill Wanlou or not, we can definitely cause internal strife in the enemy. It is best to kill him. If he can't kill him, it's good to kill Yan Rou. A vulgar person like Wuhuan, knows what counter-espionage strategy? As long as he hears the news, he will definitely react.

After all, it was Yun Chang who killed King Nanqiao, creating a good opportunity for us to use today. Every time the enemy commander died in battle and personnel change, we can try counter-essay."

Li Su said very beautifully, but she still didn't make any contribution.

This strategy is not in vain, and there is no loss if you fail to use it.

Shortly after the implementation of the counter-espionage, Zhou Tai's men were also ready to attack the city.

The Han army sent five or six hardwood slanted trench bridge vehicles; dozens of arc-shaped appearances and large protective shields with support inside were pushed to the city by the soldiers to carry out basic siege operations.

That is to say, fill in several gaps in the moat outside the north gate of Changli City, and at the same time, the crossbowman was ordered to face the archer and shoot arrows on the top of the city behind the protective shield.

The moat in Changli City was originally dug a canal from the Dayushui River to bring the live water. However, before the Han army was preparing to attack the city, it had already blocked the canal outlet in the northeast corner of the city, so the water level in the moat had dropped a little, and there was no source of live water, so it became much easier to fill it.

After half a day of excavation, the bows and arrows were shot at each other, and more than a hundred people were killed or injured in the siege, and several gaps were filled, so the troops retreated. The rebel archers on the top of the city also died or injured thirty or forty people.

However, these losses will not cause any harm to the Han army, because the one who filled the river was not elite soldiers, but was recruited by Liu Bei temporarily rewarded money and grain from the hungry people.

This is not to say that Liu Bei is false and righteous, but that the soldiers who attack cities do not need much professional quality, and they are equal to all living beings in front of bows and crossbows.

When death and injury are inevitable, Li Su asked him to give priority to middle-aged and elderly hungry people who were over 40 years old and barely physically strong to fill the army, which can be regarded as trying to protect the young and strong.

Because only Li Su knew that the war in the future would last at least ten years. Therefore, among the soldiers recruited by Liu Bei, the soldiers destined to be used as direct lines must be young.

In the meantime, other warlords generally felt that the comprehensive quality of the military qualities of 30 or even 35 years old were the best and could get started as soon as possible. However, Li Su repeatedly advised Liu Bei to try to recruit soldiers around 20 years old to train them with great care. Liu Bei was also happy to do so in line with "young and strong people's life expectancy is still very long."

The Han army retreated without any plague or fire, which really made the defenders on the city feel a little strange.

Especially that night, when they heard that the battle situation of Guan Yu's main attack on the battlefield was much more intense than here, many people became suspicious.

The next morning, Nanlou brought hundreds of strong guards to the North Gate Defense Zone and found Yan Rou.

"Mr. Yan, I heard that letters were shot from the city yesterday. Can you give me a look?"

Yan Rou was shocked: "Why did Shanyu say this? This...forget it, since you know that the letters exist, my explanation is useless - I wanted to burn them immediately and not read them, but the soldiers had already submitted them to me at that time, and I regretted it too much! I knew that after reading them, I would definitely not be able to win the trust of Shanyu, and maybe I would feel guilty.

I did keep that letter, but it was Liu Bei's counter-espionage plan! It was to ask your lord and ministers to kill each other! If the Shanyu was willing to give me a chance, I would use the trick in the near future and counter-killing Liu Bei showed my thoughts!"

The guards around Nanlou have already drawn their swords and can dismember Yan Rou at any time. Seeing that Yan Rou is so straightforward and open, he believed it seven or eight points:

"Then how do you express your feelings?"

Yan Rou wiped her face: "Liu Bei asked me to kill Shanyu in his letter, so I used the trick to say that Shanyu was closely guarded. I was a military advisor, and I had few direct troops and could not start. But I was willing to give up the northern city gate at night and let the Han army enter the city, so that the Han army would attack and kill Shanyu.

At that time, we will be ambushing the city tower near the North City Gate. After the Han army vanguard enters the city, we will put down the gate and cut off the way back and shoot all the enemy vanguards into the city. But I also said that in the front, Liu Bei may not risk entering the city himself. If Liu Bei cannot kill Liu Bei, as long as he can kill some Han army vanguards, it will be enough to show my feelings! Does Shanyu agree?!"

Yan Rou was also nervous, and after saying that, she was waiting for the verdict of fate.

If Nanlou doesn't believe him, but as long as the other party doesn't execute him immediately, he will have to silence the snake and delay time and find a way to assassinate Nanlou's surrender.

As a Wuhuan man who had never read any books, Nanlou really felt that Yan Rou's plan was already a brilliant plan in the world.
