Liu Beijun's siege seems to be a little different from what Liu Zhang thought.

Liu Zhang thought that Liu Bei's army should attack the city, it should be to build a ladder, a well, and rush the car, but if it can't work, let the soldiers and ants attach to the siege and so on.

Liu Zhang is not a person who has not seen siege warfare, when Zhao Spoon was in turmoil, Chengdu City was besieged, or Liu Zhang personally commanded and repelled the attack of Zhao Spoon's army.

The siege war is not so easy, 30,000 against 100,000, even if it is consumed, it is not necessarily Liu Zhang who loses in the end.

But. Dozens of tanks in a row, what do you mean?!

When Liu Xun saw it, his face turned pale, and he dragged Liu Zhang off the city.

What kind of chariot, this is a catapult, seventy or eighty catapults.

At the beginning, in Ruocheng, that Zhang Xi almost collapsed the city wall of the south gate of Ruocheng with thirty catapults, and now so many stay on the city tower and wait for death.

Liu Xun pulled his father and left quickly, as far away from the city tower as possible, it would be too late.

Then, the defenders of Chengdu finally appreciated the power of the heavy catapult.

Seventy or eighty catapults, all of them throwing stones, some throwing small stones, and some throwing some indescribable excrement. Well, this one is a bit lacking.

But this matter is really not Zhang Xi's idea, it is really that some soldiers who operate trebuchets are too out-of-the-box, and after Zhang Xi knew about it, he quickly stopped this behavior.

It's not that I'm afraid of disgusting, it's mainly people in this era, it's really hard for you to say whether there is a parasitic infectious disease in his Oli or something, if there is a plague, then Zhang Xi's sin will be great.

But even so, the north gate of Chengdu City, after being smashed by catapults for several days, the outer shell of the city wall began to slowly crack and peel off.

Catapults are really not easy to defend against, after all, they are a means of long-range attack.

To deal with this kind of thing, either use a bed crossbow to fight back, or send troops out of the city and burn it.

It's relatively simple for the bed crossbow to fight back, but the question is, who has the courage to brave the rain of stones and go up to the city wall to manipulate the bed crossbow?!

Moreover, the bed crossbow was fixed to the city wall, and the damage was one less than the other's catapult. As long as there is a tree, a stone and time, it can be built at any time.

As for sending troops out of the city to the field and burning the catapults. Then you have to ask if you have the ability to break through the defensive position set up by Zhang Fei.

Besides, if a catapult can smash a city wall, can't it adjust its range to smash people?!

The catapult is not unbreakable, it is the inferior side, and it is difficult to do.

Later, the Southern Song Dynasty lost Xiangyang, and it was almost the same reason, and they couldn't go out of the city to fight, so they could only let the catapult smash it, and after the smashing, the city defense and morale were gone, but there was only surrender left.

After three attempts to go out of the city and burn the catapult to no avail, but instead lost his troops and lost his generals, no matter how anxious Liu Zhang was, no one was willing to go out of the city again to die.

Don't look at the nearly 30,000 defenders in Liu Zhang's hands now, but what he actually controls is a garrison of 10,000 people, and the other 20,000 people really obey the orders of the family, and Liu Zhang can't fully mobilize them.

And going out of the city to burn the catapult, Liu Zhang didn't plan to let his garrison go at all, and sent all the troops of the family to take risks.

But Liu Zhang did this, and the family took a look. Since you Liu Zhang are so unparticular, the family will not take risks desperately for the benefit of Liu Zhang.

If you don't go, you won't go out of the city at all.

In this way, the catapult outside the north gate was still raging, and after a slight pause, it was immediately the siege launched by Liu Beijun, so back and forth several times, the defenders of the north gate suffered heavy damage, and there were four or five thousand casualties in ten days.

What's even worse is that now in addition to the north gate, the other three gates have also slowly begun to appear catapults.

The miserable appearance of the north gate, the other three gates are all in their eyes, and now when they see that such siege equipment has appeared in their own defense area, the guard will have a numb scalp again.

But fortunately, the number of other three-door catapults is not as large as that of the North Gate, and if you calm down and deal with it, you can still hold on.

I just don't know what the next battle will become, if Liu Beijun makes such catapults on a large scale, then no matter how strong and thick the walls of Chengdu are, sooner or later they will be breached.

In fact, Liu Bei Group could indeed do this, but Liu Bei didn't want to harvest a ruined Chengdu city, so he didn't do it.

The power of the catapult is not small, but the damage is great, and after the Chengdu is laid in the future, it is also a very expensive thing to repair the city wall.

Therefore, Liu Bei still concentrated the trebuchet at the north gate as much as possible, trying to exchange the damage of one city wall for the integrity of the other three city walls.

But Liu Zhang is still somewhat unwilling to surrender like this, he feels that he still has hope.

Cao Cao's power over the years has been extremely great, as long as he personally leads the troops westward, then Zhang Lu will definitely not be able to stop it, and the guards of Jia Meng Pass will not be able to stop it for long.

And on his own side, even if the outer city wall of Chengdu is broken, there is still the urn city, the urn city is broken, and the inner city Liu Zhang feels that he has not reached the point of complete exhaustion.

Therefore, Liu Zhang is indeed still insisting on the arrival of a turning point.

But Liu Zhang didn't wait for the turn he wanted to see in the end, but waited for an unexpected figure - Ma Chao.

Yes, Ma Chao still appeared under the city of Chengdu after all.

Ma Chao's appearance, not to mention that Liu Zhang didn't expect it, and Zhang Xi didn't expect it either.

Zhang Xi originally thought that in this attack on Chengdu, there might not be any Liu Zhang's surrender, and he had to attack strongly, so he desperately supervised the construction of catapults, and also offered a plan to let Liu Xun go back, maybe he could create panic from the inside. But Ma Chao actually came.

Zhang Xi wondered, how could Ma Chao come, shouldn't he be in Liangzhou to fight with those heroes?!

But Ma Chao did come, but not as Zhang Lu's general, but as a "prince of one party".

Ma Chao was too unauthentic in Liangzhou, and he surrendered and killed when he was fighting Jicheng, which caused the local heroes in Liangzhou to be in danger, so they jointly set up a bureau and pitted Ma Chao.

After more than two months of struggle, Ma Chao was finally defeated, defeated and expelled from Liangzhou, and his wife and children were all killed by the wealthy family in Liangzhou.

After the defeat, Ma Chao originally wanted to go to Hanzhong to join Zhang Lu, borrow troops from Zhang Lu, and then counterattack Liangzhou to avenge himself.

Yes, Ma Chao never really wanted to take refuge in Zhang Lu, he just wanted to use Zhang Lu to deceive soldiers and horses from Zhang Lu, and the purpose was to return to Liangzhou and be his prince.

But Zhang Lu's strength is really not very good at this time, if Ma Chao has a choice, he really doesn't want to go to Zhang Lu.

At this time, Ma Chao heard that Liu Bei was attacking Yizhou, and even surrounded Chengdu Ma Chao's careful thoughts, and suddenly moved.

Compared with Zhang Lu, Liu Bei is a standard hero in the world.

And Liu Bei not only has Jingzhou in hand, but now he is about to attack Yizhou again. Across the two states of Jingyi, the strength is definitely much stronger than Zhang Lu.

If Ma Chao goes to Zhang Lu, then Zhang Lu can only borrow a few thousand people for Ma Chao to counterattack Liangzhou, but if he goes to Liu Bei, maybe Liu Bei will give him 10,000 horses.

But there is also a risk in this, that is, Liu Bei is a person who is more difficult to fool than Zhang Lu.

But now in front of Ma Chao, there are two ways, one is to take refuge in Zhang Lu, who can only defend himself in Hanzhong, and the other is to take refuge in Liu Bei, who is famous all over the world. Ma Chao's small brain turned slightly, and he made a decision.

With Liu Bei's strength and ambition, he will definitely enter Liangzhou in the future, and he will take refuge in the past at this time, and when Liu Bei attacks Liangzhou in the future, he will definitely reuse himself.

At that time, he had Liu Bei's support, and when he returned to the Qiang tribe in Liangzhou, he would be able to summon a large army in an instant.

And with this army, Ma Chao's best result is to re-occupy Liangzhou and become a prince, and the worst result is to become a great hero of Liu Bei's group's attack on Liangzhou.

No matter how you look at it, it's better than having nowhere to go after the defeat now.

Therefore, Ma Chao made a detour from Qiangdi in the northwest of Hanzhong and entered the north of Yizhou, and at the same time wrote to Liu Bei, asking to be taken in.

As soon as Liu Bei received Ma Chao's letter, he immediately knew that the time had come to make a forced landing in Chengdu.

On the one hand, Liu Bei asked Ma Chao not to appear for the time being, and to stop the army for a while.

On the other hand, Liu Bei sent a force of nearly 10,000 to meet Ma Chao, pretending to be Ma Chao's subordinates, and then asked Ma Chao to lead this force to appear outside the north gate of Chengdu.

And what Liu Zhang saw was Ma Chao outside the north gate, showing off his might.

At this time, the last luck in Liu Zhang's heart was also completely broken.

Because of the relationship between the war and the delay of information, Liu Zhang did not know that Ma Chao was defeated and came to vote, and at his information level, Ma Chao was still a warlord in Liangzhou, a prince.

But now Ma Chao actually crossed Hanzhong and appeared under the city of Chengdu, what does this mean? !

First, Ma Chao, a warlord in Liangzhou, united with Liu Bei.

In this way, if Cao Cao wants to enter Hanzhong, he must first solve the coalition of Ma Chao and Liu Bei, and he will not be able to rescue him in a short time.

Second, Zhang Lu's grandson actually let Ma Chao lead his troops south, which shows that Zhang Lu also united with Liu Bei.

Once Zhang Lu unites with Liu Bei, then Hanzhong will not be so easy to fight, even if Cao Cao comes in person, I am afraid that he will not be able to win easily in front of the three coalition forces.

The third Ma Chao's kid is not very good.

At the beginning of last year, Cao Cao wanted to attack Hanzhong through Guanzhong, and Ma Chao and other Guanzhong princes were afraid that Cao Cao would destroy him on a false path, so they raised troops to fight and supported Han Sui as the governor.

But it's no problem for others to raise troops, but Ma Chao, a kid who raised troops, is a little inauthentic - his father Ma Teng was still enjoying his old age in Yecheng at the time, Ma Chao's rebellion, his father can have his life? !

Sure enough, although Cao Cao did not kill Ma Teng at the first time, after breaking the coalition army of Ma Chao, Han Sui and others in Guanzhong and expelling Ma Chao and Han Sui to retreat to Liangzhou, Cao Cao, who had no worries, the first thing he did when he returned to Yecheng was to cut down Ma Teng's family.

Ma Chao is a person, but he doesn't even care about his father, he appeared in Chengdu, once the city is broken. Liu Zhang was a little afraid to think about it.

Liu Bei is a person who has to nod his face to some extent, since he swore in public that he would not kill his family, Liu Zhang still believes it a little.

But Ma Chao didn't even care about his own father, he really slaughtered himself after turning around and breaking the city, and then Liu Bei took the opportunity to retreat 625, anyway, it wasn't him Liu Bei himself, and then he pretended to cry twice, and no one in the world would accuse Liu Bei of not keeping his promises.

Therefore, after Ma Chao appeared at the north gate of Chengdu, Liu Zhang struggled in his heart for more than ten days, and finally decided to surrender in Kaecheng.

Since then, Liu Bei has captured Chengdu and pacified Yizhou.
