The road to Chengdu was not smooth, and after Liu Bei lost Jiangzhou, he immediately ordered the destruction of all roads leading to Chengdu, resulting in the gunpowder army even though it carried out a forced march, but it did not achieve its previous goal, and could only barely catch up with forty miles a day.

Looking at a rugged mountain road, Yuan Yun had no choice but to sigh secretly, not only was the road difficult to walk these days, but it also rained heavily, causing the march to be slower, and in the narrow mountain road, heavy units such as tanks were even more difficult to walk.

At this moment, it was already evening, and if it was in the past, the gunpowder army would have begun to camp a long time ago, but now it was a rapid march, so it was delayed until the sun had completely set, and the army came to a standstill.

Watching the craftsmen begin to build mobile city walls on the periphery of the camp, Yuan Yun had some doubts for the first time, did these moving city walls help the Gunpowder Army, or did they drag it down?

Zhuge Liang saw that Yuan Yun's eyes had been wandering on those city walls, and he immediately understood, so he shook his feather fan and smiled: "Don't worry, my lord, although our marching speed is very slow, Chengdu will not run, sooner or later we will come to the city."

And judging from the battle report on the southern front sent yesterday, the fierce battle over there started again, and Cao Ang Shizi launched several large-scale attacks in order to hold off Guan Yu's army, and thousands of shells were shot out alone, so we still have enough time. ”

Yuan Yun nodded, then shook his head again, and then said with a wry smile: "Maybe I'm a little anxious, always thinking that as long as I win Chengdu, the world will be unified, so that I can return to the pastoral life as soon as possible, such a mentality is unacceptable." ”

Zhuge Liang smiled even happier when he heard this, and said: "Liang also longs for that kind of life, but he talked to the lord about future development before, but it gave Liang a new goal, that is, to make Luoyang as the lord said, what is called an 'international metropolis', such a city Liang has never thought of in the past, if it can really be done, it is really a great ambition in life." ”

When Yuan Yun saw Zhuge Liang speak, his eyes seemed to be shining, and he couldn't help but feel for a while, after all, according to the original history, Zhuge Liang was the person who would become the prime minister of Shu, but now he is just a mastermind by his side, even if he has an official body in Luoyang, it is not a very big official position, and now he sees that the other party seems to be full of yearning for the future development of Luoyang, and he has somewhat made up for some guilt.

"When the world is peaceful, Kong Ming might as well go to Chang'an to develop, I will propose it to the prince, I believe it will be approved, but you run Chang'an alone, according to the development order we discussed before, I believe that such an international metropolis will definitely appear in our lifetime."

"Then there is the master of labor, after all, Liang is developing in Luoyang, and he always feels that he is more constrained, so it is better to go to Chang'an alone and start over, which will be more fulfilling."

Yuan Yun saw that Zhuge Liang agreed, and his heart became happy again, now he is waiting to eliminate Liu Bei, and then he can let everyone do what they want to do, and such a day is almost just around the corner, thinking about it really makes him very anxious.

After suppressing the chessboard in his heart a little, Yuan Yuncai pointed to Zhao Yun who was walking in the distance and said, "It seems that Zilong also has something to say today, otherwise he would rather live in the wild than return to the camp, and see what he wants to say?" ”

Zhao Yunlong walked in a tiger step, and hurriedly saluted when he arrived at Yuan Yun's side, and then said with a smile: "Lord, Chengdu is close at hand, the spies I sent out three days ago have now reported that almost all the periphery of Chengdu has been cleared by Liu Bei's strong walls, and even the jungle around the city has been cut down, and then Liu Bei used these timbers to connect many mountains and organize a line of defense."

As a result, the other side has built fortifications in the middle of the mountainside, and the condescending defense of us may occupy a lot of advantages, after all, although our artillery is powerful, it can't hit so high, and this time I'm afraid it will be more troublesome. ”

When Yuan Yun heard this, he immediately searched the map in his mind, and found that there were indeed many peaks around Chengdu, and establishing a defense halfway through these peaks could indeed play a role in getting twice the result with half the effort.

Such a halfway up the mountain did make the gunpowder army's artillery lose a lot of color, and the opponent fired arrows or used trebuchets to attack in the middle of the mountain, and the range was even farther, even reaching the range of artillery.

Thinking of this, Yuan Yun looked at the mobile city walls that were being built again, this time there was no hesitation, this thing definitely has a strong advantage, even if it is very inconvenient to transport, but when it is really used, it will be found to be very valuable.

Zhao Yun finished reporting his business, and in an instant, he said: "When the world is unified, I plan to go to the north, can the lord give a few words to Cao Zhanggongzi, it is best for me to go to his side to serve." ”

Yuan Yun was stunned when he heard this, and said in confusion: "You were going to Xiliang when you were crusading against Karasuma before, why are you going to fight in the north now?" ”

Zhao Yun said with a smile: "I heard that there is Ma Chao in Xiliang, so I started to compare, now Chengdu is close at hand, once we are pacified, it is estimated that there will be no war in the world, and there is no choice to go to the north, although those Xianbei people are stupid, but they are better than others, and they ...... compete."

Before Zhao Yun could finish speaking, he suddenly stopped, because at this moment, a very dazzling signal flare was shooting into the sky from the hot air balloon, which was a warning of a surprise attack by a large army, and then the rumbling sound of horses' hooves came, and the number was extremely large, as fierce as a big flood.

Zhuge Liang was the first to react, so he immediately shouted to the herald: "Prepare for war, the heavy armor battalion will be fortified for one mile, the rifle battalion will follow, and the artillery battalion will be shelled!" ”

After a few orders were issued, the rumbling sound of horses' hooves was almost in front of them, and as soon as the incense was burned, there was already a terrible shout of killing outside the camp, and at this time I saw that several heralds had returned, and then reported the situation in the front.

Less than half of those moving walls had been built, and thanks to Wei Yan's quick response, when Zhuge Liang's order arrived, he had already pushed 10,000 heavy infantry to the periphery, just blocking the place where the city wall had not yet been built.

At the same time, the enemy's cavalry had already rushed to the front, and if it weren't for the strong shields of the heavy infantry, this charge would probably have penetrated the entire battalion, and the consequences would have been unimaginable.

While the hoplites were resisting the flood of cavalry, the sound of battle was heard on the other side of the battalion, and the guns of the rifle battalion were fired one after another, and the artillery also opened fire, setting off countless waves of sparks in the mountains not far away.

And under the illumination of these lights, Yuan Yun saw clearly that the flat land between the mountains was crowded with the heads of people who were charging, like an avalanche rolling in, even if under the intensive fire of the rifle battalion, many fell on the way, but more heads poured out from behind, giving people a steady stream of illusions.

The crackling sound of the rifle almost made it difficult to speak in the camp, whether it was Zhuge Liang or Yuan Yun, every time an order was given, it was necessary to shout to make his subordinates understand.

Soon, the side of the rifle battalion finally quieted down, because of the cover of the city wall, the opposing infantry did not succeed in charging closer, most of them died on the way, only a few small forces reached the city wall, but they couldn't imagine that the gunpowder army was camped in the field, and it was possible to build a tall wall in such a short time, so the final fate of these people can be imagined.

The heavy infantry was not as easy as the rifle battalion, and the formation was broken several times, if it weren't for Zhao Yun's Hu cavalry pad, the opponent's cavalry vanguard would immediately be killed into the camp.

And Zhao Yun was not just guarding it, soon he organized more than 3,000 people, and then the west side of the large battalion came out and launched a surprise attack on the enemy's right flank, which immediately caused a lot of confusion among the opposing cavalry.

After so many battles, Zhao Yun was not the stunned young man at this time, and after creating a certain amount of confusion for the other party, he immediately collected the team and returned, so that the enemy was shot and killed by the rifle battalion on the way to pursuit.

But this defense was still very difficult, the opposing cavalry continued to pour in, so that the heavy infantry cried, every time they were attacked, the formation would be a little slack, without the cover of steel wire and trenches, these soldiers even wearing heavy armor, still could not stop the brave cavalry charge, and the losses continued to rise.

Yuan Yun looked at the battle formation of the heavy infantry and kept frowning, he and Xu You kept urging the battalion to start assembling those city walls frantically at the moment, hoping to establish a city wall defense line behind the infantry position, as long as this defense line was established, then the gunpowder army would be safe.

Wei Yan obviously felt that the charge of the opposing cavalry was not disorganized, every time the personnel of the forward fell, they would immediately disperse to the two wings, so that the new cavalry in the rear could effectively impact the big shield positions established by his subordinates again, and after several times, the infantry battalion could still maintain the formation, which was already commendable.

But at this time, he could only grit his teeth and insist, Wei Yan looked at the city wall behind him that was constantly rising, and began to calculate the time in his heart, this time was not the time to feel sorry for the soldiers, his 15,000 subordinates were all sent to the front by him, and even the personal soldiers around him did not let go, only hoping to win more time.

Suddenly, the infantry phalanx on the right flank collapsed, and if it weren't for the fact that the soldiers of the Gunpowder Army were trained by professional soldiers on a daily basis, this rout would have been enough to defeat the whole army.

Wei Yan looked at the soldiers who were slaughtered quickly after being defeated, gritted his teeth, and sent some of the remnants of the soldiers who had just retreated in the rear again, and at the same time only heard him howl: "Where is General Zhao Yun's cavalry?" ”

A herald immediately replied: "General Zhao Yun has just returned to the camp, and just now he led 10,000 cavalry out of the formation, and at this moment he is entangled with the enemy on the left flank. ”

Wei Yan was a little relieved when he heard this, and immediately ordered: "Order, the infantry on the left flank will start to move to the right, abandon the line over there, and let General Zhao Yun block it." ”

In less than half a column of incense time when the order was issued, the rifle battalion had just withdrawn, and Zhao Yun immediately made up for the gap, just killing several enemy cavalry that rushed into the position, and at this moment, the right flank formation of the infantry battalion had finally stabilized.

However, even after dodging this charge, Wei Yan's brows furrowed a little tighter, because of the alarm from the hot air balloon, more cavalry of the enemy began to rush towards his position, and the number was actually more than the first charge.
