"Spill our gasoline and build a wall of fire on the right flank!" Yuan Yun finally couldn't sit still when he saw that Wei Yan's heavy infantry was gradually starting to disperse, so he went to the front of the battle in person despite Xiao Liu's opposition.

When Wei Yan heard Yuan Yun's order, he immediately seemed to understand something, so he immediately shouted to his subordinates, and after a short time, a group of people pushed the sprinkler truck up, and when more than a dozen sprinkler trucks were discharged, Wei Yan immediately began to order the infantry on the right flank to retreat.

At the same time, Zhao Yun's side also began to retreat gradually, it was really the other party's cavalry was too strong, it was simply a charge regardless of life and death, those knights on horseback, even if they saw a gunpowder bullet falling on the way forward, they would continue to urge the horses without hesitation, and then they were instantly blown into pulp.

Zhao Yun's Hu cavalry was casually fierce, but against these opponents who were not afraid of life and death, they naturally fell behind, so they had no choice but to retreat.

Boom!

When the sprinkler sprayed tons of gasoline, all the heavy infantry on the right flank also retreated to their position, and the enemy cavalry chasing after them was crushed by Huang Zhong's rifle battalion fire, so they temporarily chose to evade.

When the last group of infantry withdrew, Wei Yan immediately gave the order to ignite, the timing of this order was very accurate, just when a new group of enemy cavalry rushed in, the fire was in the sky, the opponent's cavalry was instantly swept in a sea of fire, the screams of people and the neighing of horses continued to come from the wall of fire.

With the blocking of the wall of fire, the enemy's cavalry finally slowed down, but hearing the sound of horses' hooves constantly wandering around the wall of fire still made people dare not be careless, and from the sound of these horses' hooves, it can also be judged that the number of the other party is very large.

At the same time, the left flank of Zhao Yun's defense also ignited a sky-high fire, and the two walls of fire immediately completely separated the enemy army from his own troops, and the general camp in the rear finally had enough time to build a mobile wall.

When the last sprinkler retreated from the front, the tall and strong walls were built, and a fortified city rising from the ground in the mountains shocked the enemy soldiers, who could not understand why the Gunpowder Army could build such a fortified city after the fire wall was extinguished.

At this time, some unwilling enemy soldiers began to hold the freshly made siege ladders, trying to break through such a city wall, they always felt in their hearts that these looking at the tall city wall was just an illusion, as long as they continued to launch an offensive, they would definitely be able to expose the magic of the Powder Army.

It's just that these charging enemy soldiers all went and never returned, and most of them died halfway through, and those who were lucky enough to rush to the city wall, after hitting the solid wall, finally understood that this was not a fantasy at all, but a real thing, but when they found this, they didn't have a chance to report it back.

The attack continued all night, and the other side did not seem to have any intention of withdrawing, and kept thinking of ways to attack the city, until the sky began to light, and the enemy army was left with only dead bodies and blackened bloodstains, and they could not even attack a single wall.

When the sun rose, the enemy's offensive finally stopped, but in the distance among the mountains and forests, you could still faintly see the army lurking in it, and it was at this time that scouts finally returned to report that the number of the enemy exceeded 100,000, most of them were cavalry.

"Why are there so many cavalry in Chengdu?" Yuan Yun asked himself in wonder, at this moment he was standing on the tall city wall, looking at the enemy army in the mountains and forests in the distance, and he felt very strange.

Zhuge Liang on the side heard this, only thought for a moment, and then replied: "The letter sent by Cao Ang Shizi before, saying that most of the people led by Guan Yu were cavalry, so they could launch a sneak attack everywhere, and they immediately fled thousands of miles away after a successful blow, causing a lot of trouble to the gunpowder army on the Shizi's side.

At this moment, it seems that these cavalry who attacked us are probably the one led by Guan Yu, when Cao Ang Shizi confronted him at Mianzhu Pass before, Guan Yu should have left, and then chose to surprise us in this area, and the people who are still guarding against the prince at this moment have definitely changed people. ”

After listening to Zhuge Liang's analysis, Yuan Yun immediately recruited an entourage, and then ordered: "Send a letter to the prince and inform him of the situation here, once it is confirmed that it is Guan Yu who attacked us, then Mianzhu Pass can launch a large-scale attack." ”

After the entourage left, Yuan Yun took out his binoculars and glanced at the mountains and forests in the distance before continuing: "The other party seems to be very familiar with the terrain here, last night's battle, they retracted into these mountains and forests as soon as the sky dawned, and these mountains and forests are very good locations, not only the terrain is high, but there are also high mountains and cliffs on the left and right sides, and we can only attack from the front." ”

Zhuge Liang nodded and continued: "Liang has already seen the terrain here, and the position where the other party is now hiding is halfway up the mountain for a long time, so that it can effectively defend against our artillery, and they are mostly cavalry, once we choose to attack, they will rush down from the mountain, which can be said to have an advantage." ”

Yuan Yun heard Zhuge Liang say this, and did not choose to answer, because he knew very well that Zhuge Liang would inevitably have countermeasures, and he would soon reveal the following.

Sure enough, Zhuge Liang was silent for a while before continuing: "Since they chose to defend in the middle of the mountain, we will give them a look in advance of the power of our moving city walls, as long as we move our fortified city to a close place, we can use artillery bombardment, we have these city walls, and the other party's cavalry can only throw rat weapons." ”

Yuan Yun nodded with satisfaction, and then added: "The artillery battalion must be allowed to choose gasoline bombs, although they have cut down a lot of trees in the mountains and forests, there are still many more, if they can be connected into a sea of fire, Guan Yu and these soldiers must stay here." ”

When Zhuge Liang heard Yuan Yun say this, his brows furrowed slightly, and finally gave the order to launch a gasoline bomb.

Looking at Zhuge Liang's somewhat hesitant expression, Yuan Yun immediately understood the other party's thoughts, the attack method of the gasoline bomb is indeed very vicious, this time the gunpowder army went out, Zhuge Liang could almost not use it, basically would not use it, but if Guan Yu's army was not eliminated as soon as possible at the moment, the gunpowder army could only be dragged here, which was definitely not a good thing for the gunpowder army who did not understand the environment here, in case the supply team in the rear was sneak attacked, it was not a joke.

When the first wall began to move, the enemy troops in the mountains and forests immediately reacted, and they seemed to be very restless, not understanding what was happening in front of them, because such a tall wall was gradually moving on the ground, although very slowly, but gradually moving towards the side of the mountain.

Suddenly, the other party finally showed the big flag, and the Guan character on it was extremely eye-catching, and after this flag was displayed, a large group of cavalry began to assemble at the foot of the mountain again, ready to attack the posture again at any time.

Yuan Yun saw Guan Yu show the banner, and saw that the other party was gathering cavalry, and immediately said with some surprise: "Could it be that Guan Yu plans to go into battle in person?" ”

Zhuge Liang was also looking at the Guan Zi banner opposite, and when he heard Yuan Yun's question, he just shook his feather fan and said: "The lord is right, Guan Yu is indeed planning to come in person, he should feel that once our city wall moves, there will inevitably be loopholes or weaknesses, at this time he really has not many options, if he continues to hide in the mountains and forests, he will only become a target who cannot fight back, and he should know our weapons very well." ”

After Zhuge Liang finished speaking, Xu You appeared, this old man had been urging the craftsmen to assemble the city wall all night last night, and he was obviously a little decadent until now, but he still gritted his teeth and went up to the city wall.

After hearing Zhuge Liang's words, Xu You immediately followed: "Our city walls are designed to facilitate movement, so even if we let the enemy army let the horses come, we just wait for work, if we can kill Guan Yu directly, or capture it alive, our battle will be considered a victory." ”

Yuan Yun was still a little worried when he heard Xu You's words, so he asked, "Have all those tanks that pushed the city wall been checked?" ”

Xu You nodded and replied: "Yuan Hou can rest assured, every old man has taken a craftsman to inspect it to ensure that it is foolproof." ”

Yuan Yun was a little relieved, and then said with a smile: "Then let's take a look at how Guan Yu broke our city wall." ”

Although the moving city wall can be moved, the speed is surprisingly slow, and after a full hour, it has only moved forward for more than a mile, but even at such a slow speed, you can still see those mountains and forests close in front of you, and it is estimated that there will be another hour to reach the destination.

The enemy cavalry with Guan Yu's banner finally began to act, only to see that tens of thousands of cavalry were divided into three groups, one came directly to the wall of the gunpowder army, and the other two went to both sides, the speed seemed to be very fast, and tens of thousands of people acted at the same time, which was completely meaningless and chaotic.

"Yuan Houke?" When the cavalry rushing straight towards the city wall was a mile away, a small group of cavalry accelerated and began to shout when they got closer.

Yuan Yun immediately laughed when he heard the other party call his name, and then said to Zhuge Liang: "Is Guan Yu using a delaying tactic?" ”

Zhuge Liang smiled: "That's right, he should be planning to delay for some time, and then let the team that went around our two wings be ready at the same time, so that they can attack us from three sides." ”

Yuan Yun smiled again, and then instructed Xiao Liu, "Go and ask the other party what they plan to do?" ”

Soon Xiao Liu was full of energy, and then asked a question, and the answer turned out to be Guan Yu to say hello, which was a kind of politeness to his old friend, and then asked about Zhang Fei, only asking whether it was life or death.

Yuan Yun shook his head helplessly when he heard this answer, and soon Xiao Liu replied with four words: delicious and delicious.

This Yang's brief back-and-forth conversation did not last too long, when the moving city wall advanced for another half an hour, Guan Yu finally launched an attack, those cavalry actually carried siege ladders, charging head-on, from this can also be guessed, this cavalry is very well-trained on weekdays, with so many siege ladders, and can maintain a fast horse speed, it is definitely not something ordinary people can do.

Rumble!

The first cannon finally howled, and a one-sided slaughter began.
