Five days later, the city of Changli was down.

Obviously, in the past five days, the Han army has completely mastered the alluvial plain between the two rivers of Dayushui and Xiaoyushui. On the west bank of the Great Chongqing River, except for the lonely Tuhe City at the southern end, there is no trace of the rebels' sphere of influence.

There is nothing to repeat about the military discussion process between Liu Bei and Li Su and Lu Su, because Li Lu and the others completely agreed with Guan Yu's suggestion - surround three and lack one, encircle Tuhe and attack Changli, and completely uproot the most important stronghold where the enemy still has grain and grass reserves.

In order to achieve this goal, while completely controlling the two rivers, two other Han army forces, each with about 3,000 troops, crossed the Great Chongqing River and established a camp 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 a natural river as a moat, so it is difficult to besiege, but when the Han army has the advantage of a water army, the rebels cannot escape from the west gate.

As long as they siege the north gate and the east gate, and leave the south gate for the enemy to flee for their lives, when they really feel that they can't hold on, they will go to Tuhe from the south gate, or count on reinforcements from Tuhe from the south gate.

It was Zhou Tai who besieged the north gate of Changli, and Guan Yu who besieged the east gate.

Zhou Tai only needs to be responsible for attacking the city gate in front of him, so the pressure is less. Guan Yu also had to take care of the need to divide his energy to prevent the camp from being attacked by enemy reinforcements, and the task was heavier.

And Zhao Yun still has the old rule of maneuvering with cavalry, ready to intercept and kill at any time.

Zhang Fei honestly took 5,000 people, part of them to defend the granary of the Han army's water village, and part of them to besiege the north and south gates of Tuhe City, leaving the east gate, so that the enemy soldiers in Tuhe could see a hope of returning reinforcements.

The besieging strength of each part of the Han army is actually at a slight disadvantage compared to the number of defenders in the city.

But who made the Han army so arrogant, I dare to surround you with fewer people than you, you have the courage to go out of the city to fight, you can't ask for it!

6,000 people around 7,000, 5,000 people around 6,000 people, and they also have to take care of the garrison, and the Hu people dare not attack the camp!

The death of the Nanqiao King has given every Wuhuan general a blow to the head: in the case of the Han army with a crossbow array, relying on light cavalry with only leather armor to attack Hanzhai is to find death!

……

On the ninth day of March, it was sunny.

After the morning dew was volatilized by the sun, Li Su also followed Liu Bei and rode a horse to inspect the camp north of Changli City, preparing for the first day of siege.

The morning light shines on the river surface of the Dayu River and the black soil on the opposite bank, a vibrant artistic conception can be seen, and thousands of ploughing horses transferred from captured lightly injured horses can be seen dragging ploughshares and galloping back and forth. Tens of thousands of farmers are busy irrigating and sowing seeds.

The valley between Dayushui and Xiaoyushui was controlled by the Han army for less than a week, so the best time to plant rice in spring was missed.

But the black soil between the two rivers is the most fertile, and it is a ripe field that has been cultivated in previous years, and it is only because of the two years of war that it has been temporarily deserted. At present, more and more displaced people are coming in, and it will definitely not work if we don't hurry up farming. Therefore, Liu Bei asked Lu Su to hurry up the organization and further expand the scope of Tuntian.

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

This is the strange scene of "the east bank of the river is still besieging the city, and the west bank of the river has begun to reclaim the fields", and it also brought the Han army's fearlessness and provocation to the fullest-

If the rebels dared to go out of the city and cross the river to slaughter the displaced people in Tuntian, the Han army would definitely teach them that there would be no return!

I believe that as long as you don't want to die and drag a few innocent murderers on your backs, you will definitely not do such a crazy thing.

Lu Su wanted to Tuntian, and only Li Su was responsible for the work of the staff officer.

At the end of the hour, the soldiers in Zhou Tai's camp had already finished cooking and began to eat breakfast, and after preparing for dinner, they would rest for half an hour before arranging to attack.

The breakfast time was advanced and was arranged in this way for the purpose of fighting, and Li Su also said that the interval between eating and fighting should be extended, at least half an hour, so as to reduce the incidence of appendicitis and reduce unnecessary non-combat attrition.

This kind of medical common sense is not very well understood by ordinary people in the Han Dynasty, and the military advisers take care of it, so implement it.

Taking advantage of the soldiers' meals, Liu Bei and Li Su took more than 100 horsemen to the north gate of Changli City first, a few hundred steps away, and patrolled the circle.

Then Liu Bei followed the strategy set by Li Su the day before, divided a few sharpshooters who could open strong bows, led by Liu Dun, the head of the Wuhuan Tu Cavalry, to a place more than a hundred steps below the city, quickly swept horizontally, and shot a few arrows towards the head of the city.

The shaft of the arrow was wrapped in a tightly rolled silk book, the content of which was to persuade Yan Rou, the military advisor of the King of Difficulty, to surrender, and there were some ominous words in it.

What "Su Zhi was captured by Wuhuan since he was a child, endured humiliation and grew up in the wind of Hu Ji, and his heart is true to Han. If it weren't for being coerced by Zhang Chun and King Nanqiao, it wouldn't have been like this. If he surrenders as soon as possible, he only needs to kill the difficult building, and he will not be blamed for the past, and he will be awarded the position of the county, and he will be rewarded with 20 catties of gold and 200 horses of silk. ”

The most vicious thing is that there are a few deliberate alterations in the letter like Cao Cao. and also hinted, "The reason why I know that the main city is now a difficult building is also because Yan Rou has reported to us before and is already leaving a way back for himself."

If you don't wipe the book, then it's not called a full set!

As for the "Nanlou" mentioned in the letter, it was the nephew of the king of Nanqiao, and the son of the king of Nanqiao was still young and could not lead the people left behind after the death of the king of Nanqiao.

Therefore, according to the personnel analysis of the main generals and officers of the enemy army, Li Su thought that the main generals who were still in charge of affairs in Changli City must be difficult to do, and they had to write like this if they wanted to be separated.

"Can Yan Rou really kill Nanlou and surrender? If he comes, will he really forgive him? He was originally sent by Zhang Chun to talk about the first evil against the King of Nanqiao, and it can be said that the evil is still above the King of Nanqiao. Now that he has killed the generals he said he had rebelled against and left behind those who instigated him, will he not be able to convince the public? ”

After Liu Bei saw the arrow book shooting into the city, he was still a little apprehensive in his heart.

The reason why they came to the north gate to shoot today was also because they had learned in advance that the north gate was Yan Rou's defense area through the observation of the siege a few days ago, and the letter shot here would definitely fall into Yan Rou's hands.

As for whether Nanlou can get it, it depends on whether Nanlou has eyes and ears by Yan Rou's side, whether he is suspicious enough and willing to ask for revenge - if he has the courage of Ma Chao, then he will definitely dare to do so.

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

"Regardless of whether Yan Rou has a chance to kill the martyrdom or not, we can definitely contribute to the infighting of the enemy army. It's best to be able to kill it, and if you can't kill it, it's not bad to let Nanlou kill Yan Rou in turn - Nanlou, a rude person, knows what kind of anti-intrigue? As long as he hears the wind, he will definitely react.

In the final analysis, it was Yun Chang who killed the King of Difficulties and created a good opportunity for us to use today's strategy. Every time the commander of the enemy army dies in battle, he can try to reverse it. ”

Li Su's words are very beautiful, and they don't take credit.

This kind of strategy does not need to be used in vain, and there is no loss if it is not successful.

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

The Han army sent five or six hardwood-roofed trench carts; Dozens of large protective shields with curved appearance and internal support were pushed by the soldiers to the city to carry out the basic siege operations.

That is, to fill in a few gaps in the moat outside the north gate of Changli City, and at the same time order the crossbowmen to throw arrows at the city head behind the protective shield to suppress it.

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

After half a day of excavation operations and bow and arrow shooting, more than 100 besiegers were killed and wounded, and several gaps were filled, and the troops retreated. The rebel archers at the head of the city also lost thirty or forty dead and wounded.

However, these losses did not hurt the Han army, because it was not the elite soldiers who filled the river, but Liu Bei recruited money and grain from the hungry people.

This is not to say that Liu Bei is hypocritical, but the soldiers who are besieging the city do not need much professional quality, and they are equal in front of the bow and crossbow.

When casualties were inevitable, Li Su asked him to give priority to middle-aged and elderly hungry people over 40 years old who were barely in good physical strength to join the army, which could be regarded as trying to protect the young and strong.

Because only Li Su knows that the future war will last for at least ten years. Therefore, among the soldiers and horses that Liu Bei is currently recruiting, those soldiers who are destined to be used as descendants must be young.

Other warlords of the same era generally still felt that the 30-year-old or even 35-year-old had the best overall quality and could get started as soon as possible. However, Li Su repeatedly advised Liu Bei to recruit soldiers around 20 years old as much as possible to train them attentively, and Liu Bei was happy to do so in line with the idea that "the life expectancy of young and strong people is still very long".

The Han army retreated so unrelentingly, which really made the defenders at the head of the city feel a little strange.

Especially that night, when they heard about the battlefield where the east gate of the city was defended and Guan Yu was attacked, and the battle was much more fierce than here, many people were suspicious.

Early the next morning, Nanlou came to the North Gate Defense Area with hundreds of elite guards and found Yan Rou.

"Master Yan, I heard that a letter was shot from under the city yesterday, can you give me a look?"

Yan Rou was shocked in her heart: "Why did you say this?" This...... Well, since you know that the letter exists, it is useless for me to explain it—I would have burned it at once and not read it, but the soldiers had already presented it to me, and I regretted it! I know that if I burn it after reading it, I will definitely not be able to win the trust of Shan Yu, and maybe it will seem that I am weak-hearted.

I did keep that letter, but it was Liu Bei's counter-plan! It is to kill each other! If you are willing to give me a chance, I will plan in the near future and kill Liu Bei to show my heart! ”

The guards around Nanlou have all drawn their swords out of their sheaths, and they can divide Yan Rou's body at any time, and when he saw Yan Rou being so straightforward and frank, he also believed seven or eight points:

"And how do you show your heart?"

Yan Rou wiped her face: "Liu Bei's letter asked me to kill Shan Yu and surrender, so I will plan and say that Shan Yu is closely guarded, and I have a military advisor and a descendant who is not much to start, but I am willing to sacrifice the north city gate at night and let the Han army enter the city, and the Han army will attack and kill Shan Yu."

When the time comes, we will ambush crossbowmen in the city towers and city walls near the north city gate, and wait for the Han army vanguard to enter the city, put down the gate to cut off their way back, and shoot all the enemy pioneers into the city - but I also said ugly things ahead, Liu Bei may not personally venture into the city, if you can't kill Liu Bei, as long as you can kill some Han army pioneers, it is enough to show my heart! Do you think so?! ”

Yan Rou was also apprehensive in her heart, and after finishing speaking, she waited for the judgment of fate.

If Nanlou doesn't believe him, but as long as the other party doesn't execute him immediately, then he can only delay time and find a way to assassinate Nanlou.

As a Wuhuan man who has never read any books, Nanlou really thinks that Yan Rou's strategy is already a clever plan in the world.

"Yan Junshi is a good plan! Then I will personally sit in Beichenglou at that time, and watch you kill the vanguard of the Han army to show your heart! ”
