Jiangling is a big city, and the width and thickness of the city wall are not comparable to the small cities of Exian.

Therefore, the Jiangdong Army spent more than 20 days just building siege equipment, and prepared forty or fifty large and small siege equipment.

Seriously, Zhang Xi was amazed.

If Zhou Yu had used these siege equipment to fight Echeng, Zhang Xi would definitely not have been able to defend it for more than ten days, wait, there seems to be something wrong?!

It seems that it took more than 20 days to build these siege equipment

Well, there's nothing wrong with it, my record hasn't been flooded, it's great.

Watching these Jiangdong troops build ordnance and then prepare to attack the city, Zhang Xi always had a strange sense of familiarity.

And the culmination of this sense of familiarity was when the Jiangdong Army attacked the city in a big way. This siege level is as bad as ever.

Siege of the city, in Zhang Xi's view, is basically to continue to maintain enough pressure, once there is a sign of a breakthrough, immediately increase the intensity, storm the breakthrough point, strive to occupy the city wall to defend, and then expand the gap and attack the city.

But this method is only used when the army has an absolute advantage, just like when Zhou Yu attacked Exian, the ratio of troops reached ten to one, so naturally there is no need to find another way to attack the city, just press it.

But now, the military strength of the Jiangdong Army is not superior.

Therefore, Zhou Yu adopted the second method of attacking the city.

Let the Jiangdong Army attack tentatively and find the weak points of the defenders' defenses. After testing for a long time, I didn't find any weaknesses in Cao Ren's defense.

Next, Zhou Yu asked the Jiangdong soldiers to have reservations when attacking the city, only fighting for an hour every day, and the siege equipment invested in a siege will not exceed ten planes, and if it is damaged, the troops will be withdrawn.

The frequency of attacks was also maintained at the level of attacking once and resting for two or three days, and the intensity of such siege lasted for nearly a month.

It was this siege method that made Zhang Xi mistakenly think that the Jiangdong Army's siege was as bad as ever, and it also made Zhang Fei frown.

If Zhou Yu's siege level is like this, then the Battle of Chibi really made Zhou Yu pick up a bargain and achieved a prestige in vain.

But Zhou Yu told Zhang Xi and Zhang Fei with practical actions that he really didn't waste his name.

Just a month after the continuous low-intensity siege, Zhou Yu suddenly ordered the Jiangdong Army to attack on all fronts, with all forty siege vehicles put into operation, and three city walls to attack the city with all their might.

This sudden change in rhythm stunned the Cao army, who was accustomed to the rhythm of the Jiangdong army's siege, and the three city walls were all in a hurry, and the anxious Cao Ren personally led the troops to the city tower to supervise the battle, which barely blocked the attack of the Jiangdong army.

But even so, the Jiangdong Army still did not intend to withdraw its troops after an hour, and maintained the intensity of the attack from morning to afternoon.

Cao Ren saw that this was not a solution, and if he let the Jiangdong Army attack it like this, he would suffer a lot of losses if he didn't do it on his side.

Cao Ren, who didn't care so much, led the cavalry out of the city again, intending to kill the attacking infantry of the Jiangdong Army and burn the siege equipment.

Zhou Yu would naturally consider Cao Ren's cavalry going out of the city, but Zhou Yu really didn't have a good way to deal with it.

Zhang Fei's soldiers were less than 1,000 people, which was not enough to be disassembled and used, so Zhou Yu led the Chinese army to attack the south gate, and Zhang Fei was responsible for the cavalry defense of the south gate, and cooperated with the crossbowmen to shoot the cavalry that attacked out of the city.

The Jiangdong Army officers and soldiers of the other two gates should attack Cao Ren's cavalry, and the order given by Zhou Yu was to harass with bows and arrows, and it was really impossible to temporarily retreat, the purpose was not necessarily to attack the city, and it was also a great achievement to kill and injure Cao Ren's cavalry.

Anyway, now Cao Ren only has seven or eight hundred cavalry, and he will have to feel distressed for a long time if he dies, and when Cao Ren has no cavalry available, he will only have one choice left.

Cao Ren can't help it now, he doesn't lead the cavalry out of the city, as soon as the offensive rhythm of the Jiangdong Army comes up, the three city walls are warned everywhere, if he leads the cavalry out of the city, there will always be some losses every time.

The east and west gates are better, at most there are unlucky ghosts who are injured by the loss, and the casualties are only in the single digits.

But once the south gate took the risk of attacking, he would have to face the arrows of Zhou Yu's strong crossbowmen, and he couldn't break through, and he would damage nearly a hundred cavalry when he went out.

If this happened a few more times, Cao Ren felt that his cavalry would be finished sooner or later.

And Cao Ren also needs to leave some back roads for himself, cavalry is a sharp weapon to open the way, and it can't all be lost under Jiangling City, in case it can't be held one day in the future, and cavalry is needed to take the lead when withdrawing.

For this reason, after losing a few times, Cao Ren was a little afraid to let the cavalry out of the city anymore, so he just cowered in Jiangling City and waited for help.

But there is one point, Cao Ren gradually realized that something was wrong.

The food, grass and ordnance that were supposed to be in place three days ago have not come until now.

The military law is strict, and the consequences of missing the deadline are very serious, if there is no legitimate reason, then Cao Ren, who is definitely going to be beheaded, does not believe that Xiangyang will deliberately delay the support of grain, grass and ordnance.

Sure enough, Cao Ren didn't have to wait too long, and the support grain, grass and ordnance from Xiangyang arrived, but unfortunately, the number of documents and the physical object were seriously inconsistent.

At first, Cao Ren thought that some unlucky ghost wanted to taste what military law was like, but when he asked the escort officer, he realized that it was not the wrong goods, but that he was robbed by someone.

The person who dared to rob military supplies in these years was definitely not an ordinary person, not to mention that the characteristics of the robber were super obvious - the beard grew and remained until his chest.

Cao Ren instantly knew that his back road was cut off, and the person who broke it was Guan Yu.

The generals of the Cao clan generally have a bad impression of Guan Yu. Who made Cao Cao like Guan Yu so much, it made the generals of the Cao clan feel a little uncomfortable.

Cao Ren didn't like Guan Yu either, but it didn't prevent him from recognizing Guan Yu's ability to lead troops, and immediately began to ask the escort officer, how many troops Guan Yu had, where was it robbed, why didn't he rob them all, and he actually had a little left for himself? !

The escort officer quickly replied.

Originally, the escort was unfavorable, and it was necessary to be held responsible, but now that there is an opportunity to shake the pot, of course the escort officer is desperately blowing Guan Yu to death.

The number of troops was said to be tens of thousands from thousands by the escort officer, and it was obviously robbed in the north of Nanjun, and the escort officer was stunned to say that he was besieged by Guan Yu not long after he left Xiangyang.

The cowhide was blown so big that the last question could not be answered - why was there a little left?

The more Cao Ren listened, the more he felt that something was wrong, if Guan Yu could lead tens of thousands of horses to appear near Xiangyang, then what kind of ordnance and food would he rob, wouldn't it be okay to attack Xiangyang directly?!

There are only more than 30,000 people stationed in Xiangyang, and some local wealthy families with two hearts have to be suppressed internally, and the troops are not enough.

Hearing what the escort officer said at the end, the reason why Guan Yu didn't snatch all the food and ordnance was because Man Chong led the troops to support and repelled Guan Yu's attack, which was nonsense.

Full Pet is stationed in Linfang, the north of Nanjun, and it is almost close to Jiangling, which door is near Xiangyang?!

Also, with the ability to be full of favor, there are only thousands of defenders in addition to the frustration, how can he repel Guan Yu, who commands tens of thousands of soldiers? !

Cao Ren suddenly realized that the escort officer was lying, and after repeated questioning, he finally knew the truth.

Guan Yu did go to the northern part of Nanjun, but he only brought three or four thousand people, so after he burned some of the grain, grass and ordnance sent from Xiangyang to Jiangling, he saw that Man Chong brought people to rescue, so he took the initiative to retreat.

This is a very troublesome matter.

Being harassed so much on his supply line, although he can still make some additions, no one can stand it after a long time.

So Cao Ren hurriedly repaired a book and asked people to take it to Xiangyang in the starry night and hand it over to Le Jin, who was stationed in Xiangyang.

On the one hand, let him send more people to protect the materials sent to Jiangling, and on the other hand, let Lejin organize soldiers to encircle and suppress Guan Yu.

As for whether Guan Yu can be exterminated. This is not within Cao Ren's consideration.

Cao Ren's duty is to guard Jiangling, and he is harassed by others on the back road, so naturally he is responsible for Lejin.

As for the difficulties faced by Lejin, Cao Ren will not think about it, this kind of thing is the responsibility of a military commander of Lejin, and he Cao Ren does not need to be responsible for Lejin.

And after Lejin received Cao Ren's letter, he also had a headache.

Cao Cao's defeat in Chibi made Xiangyang also floating, and the troops he had on hand were not enough to suppress the local wealthy families, how could there be a way to divide the troops to encircle and suppress Guan Yu.

Besides, doesn't he know Guan Yu's ability?!

At the beginning, Xu Huang and Man Chong led 10,000 troops to Hanjinkou, but they were defeated by Guan Yu and 5,000 sailors. How is this battle fought?!

If you want to encircle and suppress Guan Yu, you must bring more than 10,000 people, and you have to be led by a famous general, so you can't let him give up the duty of Xiangyang Taishou and run to lead the troops in person.

But Cao Ren's request, Lejin can't ignore it.

The importance of Gangneung is not to mention Cao Ren, his surname is Cao.

Therefore, Le Jin repaired the book to report the situation to Cao Cao in Xudu, and suggested that Cao Cao transfer troops from Runan to Xiangyang to help Jiangling maintain the grain route.

On the other hand, he ordered to give the Linfu guard general Man Chong and the Fancheng guard general Xu Huang, and let the two people send troops to attack Guan Yu in the south and the north, and strive to expel Guan Yu from the hinterland of Jingzhou.
