After being sent by Zhao Yun to show off his flags and cursed the army so hard that the guards in Jiangzhou City were indeed in a state of chaos and were in chaos for a while.

Some people have already secretly surrendered, and they only regret not being the supreme commander and have no right to offer the city directly, so they have to wait for the opportunity for the time being. Maybe in the future, they will wait for the official attack on the city, and offer a door or something in chaos, and make a stepping stone to save their lives.

Seeing this, Li Su was not disappointed. He knew that Jiangzhou was the capital of Ba County after all, and the heart of the entire eastern front of Shu. How could Liu Yan not pay attention to his confidant and iron-core generals guarding him?

If we could surrender here as soon as we persuaded us, then we would not have to fight any wars along the way until Mianzhu, because the will of other cities in resistance would definitely be worse than that in Jiangzhou.

"The enemy is a little confused, which means that the imperial edict and the divine punishment have both worked. In the future, just create some chaos and pressure. Since they refuse to surrender directly, it is probably Yang Huai and Li Yi who have dead and hard elements among the main military generals, so they can only kill them. As long as they die or become in chaos, other people who want to surrender will definitely offer their doors."

Li Su thought to himself, so he discussed with Guan Yu and Zhang Fei, asking them to lead 10,000 troops each to deploy siege weapons on the northwest side of the city, and prepare to attack the city. (The Jialing River and the Yangtze River on the southeast side are respectively the Jialing River and the Yangtze River. The city is built directly along the river, so it is impossible to attack)

Because the army came by water and could transport heavy siege weapons and components with ships, most of the wooden structures of the catapult can be dismantled using the Diaoyu City battlefield and assembled on site outside Jiangzhou City, which is much faster than the new logging in place - just like when playing "Age of Empires", a new trench trench machine was built, and the speed difference between the existing trench machine was expanded.

However, during the battle in Diaoyu City, there were no rushing vehicles, trench bridge vehicles, or wooden donkey vehicles (cars used for cover and excavation, and can also cover and fill the moat)? So these equipment still have to be built in stock.

Just two days later? About fifteen counterweight catapults were built on a position about two or three hundred steps away from the northwest of Jiangzhou. Dozens of simple wooden donkey carts were also built, and hundreds of huge rattan signs for covering arrows.

Two or three thousand crossbowmen shot arrows at the top of the city under the cover of the rattan array? The wooden donkey cart covered the soldiers and filled some gaps in the moat.

The defenders on the city wall also shot arrows and tried to delay the operation speed of the Han army? But the firepower density was obviously not as strong as that of the Han army, and they were quickly stunned. They chose to retract and dared to shoot without target behind the female wall wall. Even a little cross-fire side-fire angle would not leak.

Some hard-working officers on the city were plucking up the courage to pull the supervisory team to beat and whip the archers? They were asked to aim and shoot arrows, and they were not allowed to shoot randomly, but they soon paid the price. Several supervisory officers thought they were standing far away from the wall and not on the direct ballistics of the Han crossbowmen under the city? So they were not worried about safety. As a result, some gravel was thrown, or scattered powerful crossbow arrows flew past, directly taking away the lives of the officers.

It turned out that the Han army's throwing carts did not use single-headed bullets this time, but used gravel bullets wrapped in bamboo cage baskets? It can pour dozens of small stones weighing half a pound to one pound at a time, and the coverage and killing effect is many times stronger than that of single-headed bullets.

Of course? Because the technology is not yet mature, relying on more than a dozen catapult cars alone will not suppress the city. But the key is that the quality of the Han army's crossbows is far higher than that of the rebels - when Wu Kuang left Luoyang? He received two thousand high-quality crossbows and waist-induced crossbows from the arsenal of the capital in full. This is much stronger, such as the crossbows commonly used by local troops outside today, which is much stronger with arm strength.

These two thousand individual crossbows were left with some of the Gao Shunxing camp outside Jianmen Pass? All the others were taken to the front battlefield? More than a thousand such crossbows? Compared with ordinary bows and arrows produced locally by the defense, the gap came out instantly.

The Han army's crossbow was shot through two hundred steps, and the arrows shot to the top of the city could still penetrate the leather armor. If it was penetrated with a zigzag, the gap between the iron sheets could be squeezed into the instant.

This kind of shooting state lasted for only a quarter of an hour, and the hard-working officers in charge of the battle were seriously injured. They could only allow the archers guarding the city to shoot blindly and shoot, without any threat.

After two days of leisurely attack, the Han army collapsed more than half of the heights of several city walls. The Jiangzhou city wall, which was three and a half meters high, had the largest gap of only one and a half meters, which was three and a half meters, and the ladder could rush up in a few steps. There were several large gaps on the moat that could easily pass through.

...

Late the night after the siege began, Zhang Su, an important civil servant in the city, patrolled the city tower with concern.

Faced with such pressure, he had to consider the issue of surrendering.

Zhang Su is also considered to be from a famous family in Shu, but he is not the four scholars of Shu Confucianism, such as Dong, Ren, Yang, and Chen, and can only be considered as the second echelon. The so-called second echelon is the tribe and subordinates. The disciples hide the powerful men and the strong men and the fields, and the number of children and children should not exceed 10,000. Including the elderly, weak, women and children, it is only 20,000 to 30,000.

The Dong, Ren, Yang, and Chen families mentioned earlier all started with tens of thousands of hidden men. The population controlled by the four surnames can be 500,000, accounting for 100,000 of the entire Chengdu Plain. Therefore, when Liu Yan's previous life, Xie Jian was said to be greedy and plundered, which aroused civil unrest. There must be greed and despair, but it caused a change. It is estimated that the four Shu Confucian sects did not want to be identified and hidden in the houses that made people resist.

Because it was the second echelon, Zhang Su's family did not directly lose in Liu Yan's killing of big families, so Zhang Su was still quite loyal to Liu Yan. Later, Liu Zhang took office and even appointed Zhang Su as the prefect of Zhang Su's county early, so that his younger brother Zhang Song later sold his owner to seek honor, and Zhang Su also exposed Zhang Song that led to Zhang Song being killed.

Of course, all this has not happened yet. Zhang Su himself was just a middle-level official in his thirty years old. His younger brother Zhang Song was a teenager younger than him and had not yet entered the official career. At the same time, even though Zhang Su was loyal to Liu Yan, he knew that Liu Bei was taking over with an imperial edict, and his reputation was completely unremarkable, so he would not object to Liu Bei.

"But... Ziqiao and his relatives in other clans are all in Chengdu, Mianzhu and other places, and are controlled by Liu Yan. If I offer my family here, what should I do if my tribe members are affected by disaster? I am afraid that some other civil and military officials from prominent families in the city are also concerned that some tribe members are detained by Liu Yan in Chengdu, so they dare not surrender easily and harm their family members...

We have to find a way to contact Liu Bei and see what conditions they can give. We have not yet announced that we have surrendered for the time being, pretend to take us as prisoners, and wait until we take Chengdu in the future, and then we will redeem our reputation for the founding city and restore our official position..."

Zhang Su thought about it for a while and decided to write a secret letter and shoot it out of the city.

However, there are also problems with the operationality of the archery book when it comes out of the city.

Because the reckless generals who were loyal to Liu Yan, Yang Huai, Li Yi and others, personally guarded the city gates on the west and north sides, and handed the east gate facing the Yangtze River not important to the Yangtze River defense to Zhang Su and others. If you shoot arrows outside the city, there will be not many Han warships on the river, and the Han army does not expect to block the water traffic in Jiangzhou City. How can the Han army pick it up?

"Forget it! Take a risk, carve a few simple words on the wooden board, carve a few more pieces, and drift out. I hope that if there are those caught by the Han army, just make an appointment with a secret code in advance."

...

The next morning, Guan Yu's army, who was responsible for the north side of Jiangzhou, caught a wooden board that rushed to the shore in the early morning by the soldiers patrolling the riverside, and then searched carefully. He saw that there might be some on the river. But because the patrol ships could not catch up, he had to give up.

Don’t think that things like drift bottles can be discovered to be of great luck, because as long as the army has a large number of people, the probability of superposition is still considerable.

In history, Fu Youde, a general of the Ming Dynasty who destroyed Shu on a similar route as Deng Ai, smuggled through Yinping to take down Jiangyou, threw many wooden boards into the Fu River with the words "Ming Army Breaks the Jiange Road". After drifting for 1,500 miles, they were picked up by Tang He, the commander of the Ming army's Eastern Army who was blocked outside Qutang Gorge. Only then did Tang He know that the northern line had broken through, and then made up his mind to attack and break through the Three Gorges of the Yangtze River to take down Baidi City.

Tang He could even pick up drift bottles upstream of 1,500 miles, but it was normal for Guan Yu to pick up drift bottles ten miles away - Chongqing, which was only a little distance away, didn’t even come out of Longtou Temple.

After the sentry showed Guan Yu the wooden board, Guan Yu immediately handed it over to Li Su, who was the military supervisor.

"Boya, look at this secretary, what is the authenticity of this letter? Could it be that the fake Ba County Chief Zhang Su is willing to offer his door?"

"Oh? When I look at it carefully." Li Su became interested when she heard this and immediately began to take a closer look.

Zhang Su’s wooden board states that “If the city is broken, please pretend to take advantage of the unprepared defense and successfully attack, it has nothing to do with the guards. However, it should be ensured that Chengdu is captured and the surrendered generals were rescued and the families detained in Chengdu were rescued, and the generals were surrendered and the officials were restored."

Moreover, Zhang Su also emphasized that "after surrender, he will provide a list of other colleagues who are interested in the Han Dynasty, hoping that the treatment of these people can be retained." This is obviously to make a bargaining chip in his hand and be a "middleman in the business position to keep the official position". In the future, those colleagues who have maintained their positions through his own ways will not be grateful to him.

This official fan is also very self-protection-oriented!

At the end, it also emphasized the difficulty of replying, so if you are willing to agree, don’t reply. Just send a warship outside the East City Gate on the night after the conditions are agreed, and shoot three waves of rockets at the head of the city. The defenders will secretly open the door and present the door the day after receiving the rocket signal, and receive the warship into the city.

"The retreat is so detailed, and the retreat is so thoughtful, so I should have surrendered sincerely. Moreover, the East City Gate is facing the Yangtze River and there is no urn. If the water gate is opened and the warships are allowed to enter directly, it is really impossible to play any tricks."

Li Suru thought to himself and told Guan Yu the result.

Guan Yu asked simply: "Then let's act according to your inner response?"

Li Su: "Let Youping and Xingba be the pioneers, and bring more warships and troops at that time. In addition, starting tonight, we will also launch a night offensive against Ximen and Beimen, so that Yang Huai and Li Yi will be distracted and do not doubt the direction of Water Gate."

Everything was arranged according to the plan. After three days, the Han army even began to attack the city at night, leaving the defenders exhausted themselves.

On the first night, he replied to Zhang Su from the East Gate by leaning against the whistle and rocket.

The next night, Guan Yu took thousands of elite troops and set off for dinner at the third anniversary, and took hundreds of large and small warships to the east gate of Linjiang. Then at the fourth anniversary of the night, the water gate was opened at the top of the city, and the warships rushed in.

Zhou Tai rushed up the city tower as instructed, controlled the situation, and politely captured Zhang Su, who had "here to resist bravely."

At the same time, the war at the north gate of the West Gate was not over yet. The shouts of killing disturbed Yang Huai and Li Yi's attention for a while. When they came back and forth to defend, two or three thousand Han troops had entered the east gate and controlled the entire section of the city tower and walls.

The rebels wanted to resist, but they had already become a street fight and were soon destroyed by the brave Danyang soldiers and Banyang barbarians.
