By the time the first mountain defense line broke through, more than a month had passed, and these fortifications built in the middle of the mountain did play a role in slowing down the attack of the Gunpowder Army, but after the battle at the airfield, the soldiers of the Gunpowder Army had accumulated a lot of experience.

As a result, in the later battles, those strong mountain defenses no longer seemed so difficult to break, and the use of a large number of explosives made those fortifications built in the middle of the mountain become the biggest damage to the defenders.

Every time a large area of explosives resounded throughout the world, a large number of defenders in the mountain would die, and this kind of large-scale blasting, the gunpowder army became more and more familiar with the use, so even if there was such a line of defense, everyone already seemed very indifferent.

After handing the telescope to Xiao Liu on his side, Yuan Yun immediately hung a graceful arc on the corner of his mouth, and then looked at Zhuge Liang, who was still holding the telescope, and then said: "The day of breaking through Chengdu is not far away, and the scout will return to report, saying that the line of defense behind is basically the same as these, so it seems that there is not much difficulty." ”

Zhuge Liang also put down the binoculars when he heard this, then shook the feather fan, and said: "The baggage sent by General Xu Yi is enough for us to use for a long time, so in terms of manpower distribution, Liang plans to send more people to repair the road, and the road from Yong'an to Jiangzhou is basically formed, and the road from Jiangzhou to Chengdu should be started." ”

Yuan Yun heard the matter of road construction, and couldn't help but secretly smile bitterly, he didn't think that the road would be built so quickly, because in his mind, he always thought that the road should be like those highways in later generations, when he heard the speed of road construction, he smiled, the road in this era is just a slightly smoother loess road, there are 100,000 people building at the same time, it will naturally be very fast.

"What do you think Liu Bei is doing?" Yuan Yun suddenly changed the subject.

Zhuge Liang thought for a moment, and then replied: "At this time, he should be preparing for the worst, but Liang is a little worried that he will choose to surrender to the imperial court." ”

Yuan Yun didn't care about this worry, shrugged his shoulders and said: "No, even if Liu Bei chooses to surrender, Prime Minister Cao Cheng will not accept it, I'm afraid that if we want to kill Liu Bei, Prime Minister Cao Cheng is still more anxious." ”

Zhuge Liang nodded and said: "I hope it's best to do so, otherwise once Liu Bei really chooses to surrender, our army can only stagnate, so staying for one more day will cause huge pressure on the logistics supply of the army, even if we have very good means of transportation, it is still difficult to offset the waste of long-distance transportation, and the food hoarded in Luoyang is also limited, Liang has already calculated that we can wage a war on such a large scale for a maximum of one year, and no matter how long it will inevitably cause a vicious circle in all the workshops in Luoyang, It will have great disadvantages for subsequent developments. ”

Yuan Yun is very clear about this problem, not only is the production pressure in Luoyang extremely high now, but these soldiers who have come out have also somewhat developed some war-weariness, after all, it has been almost half a year, and it is fake that he doesn't want to go home after such a long battle.

Looking at the gradually falling sunset, the temperature is still very hot, it is indeed not a good thing to enter Shu in the summer, now not only the soldiers, but even Yuan Yun himself feels very tired.

"The back line of defense, we must take it within ten days, and I don't want to delay it any longer, capture Chengdu earlier, cut off Liu Bei's head, so that we can return to Luoyang as soon as possible." After Yuan Yun finished explaining, he had already climbed down from the watchtower, looked at the various people who were still busy in the camp, and couldn't help but smile heartily.

Now that the general trend has basically taken shape, Liu Bei's defeat is also a matter of recent times, so the unification of the world is also close at hand, and now it is time to consider the future, after all the battles, all positions must be removed in the fastest way, and then live the life of his marquis leisurely in the Yuan Mansion in Luoyang.

Rumble!

While Yuan Yun was thinking about the problem, a huge explosion suddenly sounded at the foot of the mountain in the distance, and then he saw a large-scale collapse on the side of the mountain, with countless corpses rolling between the rubble, and then turned into a ruin.

When the voice finally quieted down, Yuan Yun said to Zhuge Liang beside him: "The guard over there in Mianzhu Pass is Meng Da, I think this person can be encircled." ”

Zhuge Liang was stunned for a while, and then said: "This person Liang doesn't know much, does the lord have any channels to obtain information?" ”

Yuan Yun didn't know how to explain it, so he simply thought that Zhuge Liang was right, so he continued to nod and said: "This person is a subordinate of Liu Zhang, and he was forced to take refuge in Liu Bei, so he will not be like Guan Yu in loyalty, if Cao Ang's prince can envelop him, then Mianzhu Pass can naturally be self-defeating."

Now the form of Yizhou is very clear, Meng Da is a smart person, and smart people will not choose what die-hard loyalty, so the chance of this person being encircled is very large, I have asked Cao Ang Shizi to pay attention, I hope to get a good news. ”

Zhuge Liang didn't express any opinions, now he almost doesn't care much about Yizhou's strategy, he cares more about how he will run Chang'an after taking Yizhou, after seeing so many new ideas in Luoyang, he has formed a set of goals in his heart very early on.

"I don't want Cao Ang Shizi to agree to hand over Chang'an to Yu Liang to take care of later, now Liang is a little anxious, if the lord is free, why don't we talk about construction and development."

After Zhuge Liang finished speaking, he looked at the sky, and then continued: "It's still early, it's better to go to the lord's camp to mix some tea." ”

Yuan Yun saw that Zhuge Liang did not do anything for Meng Da, but talked about the future development of Chang'an, and couldn't help but smile bitterly again, feeling that even if the world was unified, he might not be able to be a mixed marquis as he wished.

After thinking about it, Yuan Yun smiled heartily, pointed to the location of the camp tent, and said: "Then go to my place to drink tea, and tell Brother Kong Ming about foreign trade management, Chang'an will probably not develop in the future, but trade." ”

After another half a month, the gunpowder army finally broke through the last line of defense on the periphery of Chengdu, Zhuge Liang's strategy was very good, and he specially chose some unfairly strong places to break through, resulting in Liu Bei sending reinforcements all in the wrong direction, because a large number of reinforcements in Chengdu went to the weaker position to defend, but it just deviated from the offensive line of the gunpowder army, resulting in every fortification being broken, and the rear did not have time to organize defense again, so that the speed of the gunpowder army's attack increased greatly.

After three days, the gunpowder army finally set up a camp in the eastern suburbs of Chengdu, the camp of 100,000 people stretched for ten miles, from the city wall of Chengdu, you can only see a piece of black pressure, every night, those camped positions, more like the stars in the sky, densely packed with all fire.

Yuan Yun did not choose to attack immediately, but adopted Zhuge Liang's suggestion and first sent Zhao Yun's troops to establish a new camp on the northern front to prevent the defenders of Mianzhu Pass from coming to the rescue.

Zhao Yun built a strong defensive line in three days, and then the gunpowder army besieging Chengdu fired the first shells, and then the fierce siege began.

The existence of a mobile city wall makes the advance of the gunpowder army very efficient, after all, the city of Chengdu is almost built between several peaks, the terrain is very high, and there is a very wide moat, without a certain protection, the artillery battalion really cannot enter the effective range.

The bombardment lasted four days, during which the defenders of Chengdu organized several desperate charges, and although they lost many men, they also breached several artillery positions, and skirmishes like this were fought several times a day.

The reason why he chose to bombard outside the city all the time was because he found that Liu Bei had completely turned Chengdu into a posture of all the soldiers, and when the gunpowder army entered the city from the broken city wall for the first time, the first force it faced was some ordinary people with wooden sticks.

This battle into the city ended with the retreat of the gunpowder army, because no one is like a person who has a reputation for slaughtering people, even if the army's killing talents are very indifferent, but Yuan Yun will never let this happen.

After another three days, the intensity of the bombardment also weakened, and Yuan Yun began to tentatively tell the people in the city to give up resistance, but these people who had been bewitched by Liu Bei for a long time would not listen at all, and they resolutely believed that the gunpowder army led by Yuan Yun would start a massacre once the city was broken, and such things were common in this era.

Such a large army besieged Chengdu for a whole month, although the shelling continued every day, Liu Bei would always send the dead soldiers to fight hard, but their number was really very large, it seemed that no matter how many soldiers died, they could still organize a larger-scale sneak attack out of the city the next day.

Although the siege was disturbed during this month, there was good news from Mianzhu Pass, Meng Da chose to surrender, and in order to show his resoluteness, he personally killed Ma Liang and Ma Tan brothers, and sent their heads to Cao Ang to make a vote.

When the news was transmitted back to Chengdu, some gunpowder soldiers who had infiltrated the city soon began to spread deliberately, and the results were very satisfactory, and a large number of people began to waver.

In order to cooperate with this matter, Yuan Yun even released some captured soldiers and let them return to the city, and there was no shortage of armed personnel of some ordinary people, but when these people entered the city, they were strictly cut off by Liu Bei and blocked them all at the city gate.

After several days and nights of confrontation, the released captives finally mutinied, tried to force themselves into the city, and were finally massacred by the defenders.

This incident directly led to the division of the forces in the city into two factions, one faction was still loyal to Liu Bei, and the other faction began to deviate, and Liu Bei had to order the city gate to be opened in order to calm the resentment in the city, so that the prisoners could return.

After these captives entered the city, they were not free, they were forcibly arranged in one place, and there were defenders to strictly guard, so that these Chengdu soldiers who were brave and abnormal before, seemed very discouraged, after all, they were willing to pay for their lives at the beginning, but they fought with the gunpowder army outside the city, and at this moment they got such an end.

So this specially set up prisoner camp in the city, and finally under the instigation of some people, they began to resist, and they even succeeded in hitting Liu Bei's mansion, but because of the disparity in strength, they all died in the end.

Those who instigated the captives to rebel were naturally sent in by Yuan Yun, with the aim of destroying the peace in the city, and after this uproar, more and more people turned away from Liu Bei, and most of these people were veterans under Liu Zhang's subordinates before, and they basically lost a lot of power after Liu Bei entered Shu.

Now these forces are gradually starting to rise under the pressure of the gunpowder army outside the city, especially when the news of Mianzhuguan comes back, this force has developed to an existence that is enough to shake the stability of the city.
