Deng Ai immediately reacted and shouted:

"It's not good, our army is going to be besieged on this mountain, hurry! Quickly pass on our military order, the whole army retreats, and retreats to Nan'an! ”

Deng Ai's order was soon passed down by the heralds, and the Wei army was only a little proud of the battle leader of the Lushan Mountain, but in less than an hour, it became like a pins and needles in the Lushan Mountain, and he was eager to leave this place immediately.

Under the leadership of Deng Ai, the Wei army began to try to break through, but soon, Deng Ai saw the heavy armor of the Qilin army that he remembered in the Battle of Longxi.

At this moment, the Qilin army has already lined up a formation between the official roads of Lushan and Nan'an, and is ready to fight a bloody battle with the Wei army just after the Wei army breaks through.

Behind the Qilin Army, there were a large number of Hun cavalry and Liangzhou iron cavalry galloping back and forth. Those hateful Hun cavalry, while running, kept shooting bows and arrows at the Wei army's front, forcing the Wei army to retreat again and again.

Deng Ai saw that the arrangement under the mountain had been completed, and I was afraid that it would be very difficult to rush out today. So he immediately asked a sentry horse beside him:

"Are the soldiers and horses of our army responsible for capturing the water source of Koji Mountain still alive? Can our army's water supply be guaranteed? ”

The sentry horse said: "General Qiyu, the shouting and killing sound at the water source shook the sky, the villain has sent people to investigate, the thousand troops stationed at the water source have been defeated by the Liangzhou iron cavalry of the Shu army, most of them fled to the mountains, and a small number of them fled without a trace, and our water source was lost." ”

"What?!" Deng Ai was shocked, he didn't expect that the thousand troops he sent would be defeated by the Shu army so quickly, and as a result, Deng Ai's water source would be cut off.

"Oops, our army's water source is cut off, if the Shu army traps our army in the upper mountain, besieges but does not attack, and the military rations carried by our army are seriously insufficient, and within seven days, our army will be defeated!"

So he made up his mind and said: "No, our army must break through, otherwise it will sit and wait to die, and order all the troops, with me, to break through to the east, no matter what the cost, our army must break out." ”

So the Wei army on the entire mountain was quickly assembled, and Deng Ai commanded more than 24,000 troops, rolling down to the east, like a tiger descending the mountain, frantically charging down the mountain.

When rushing to the foot of the mountain, the ten large phalanx of two hundred people of the Qilin army was already in full array, and there were Xiliang iron cavalry on both wings of the phalanx, and in front of the phalanx were the Hun cavalry that gave Deng Ai an incomparably headache.

Deng Ai knew that the Hun cavalry did not dare to fight with themselves, as long as the army went down the mountain, the Hun cavalry would inevitably retreat, the most difficult was the Qilin Army, this army was extremely well equipped, and good at fighting, although its own strength was several times that of the Qilin Army, I am afraid it would be difficult to break through the defense line of the Qilin Army, and there were a large number of cavalry on both wings.

So Deng Ai ordered loudly: "The pikemen are in the front, drive away the Hun archers, and after driving away the Hun archers, the pikemen will attack the Shu cavalry along the two wings, and the middle line will be charged by the sword and shield hands, and the line must be torn apart by the line of the Shu army's Qilin army, and the crossbowmen will be in the rear to press the formation." The whole army, follow me to break through and kill! ”

Deng Ai shouted, and Wei Jun immediately followed Deng Aishan and shouted.

"Kill!"

Suddenly, the shouting of killing in the mountain of Koji Mountain shook the sky, and the Hun archers on the side of the Shu army soon shot arrows like rain, causing heavy casualties to the dense Wei army in the charge.

At this time, the Wei army had no choice but to charge bravely without avoiding arrows and losing ground, so as to have a glimmer of life.

According to the previous deployment, the pikemen of the Wei army were in the front, and after approaching the Xiongnu archers, they quickly charged to the archers, wanting to fight the Xiongnu archers in close combat.

The Xiongnu archers were now all equipped with stirrups, and their riding skills had made a qualitative leap, and they turned their horses' heads one after another, scattered along the two wings, and while retreating, they stepped on the stirrups and fired arrows at the Wei army on their horses.

The pikemen of the Wei army had to withstand the rain of arrows and pursue the Hun cavalry desperately, to drive away these hateful Hun archers.

As the Shu archers and pikemen of the Wei army gradually spread out towards the two wings, the Wei army's phalanx of sword and shield hands began to assemble at the foot of the mountain, facing the ten Qilin army formations in front of them.

After the Wei army completed the formation, the rumbling war drums in the formation suddenly sounded to the sky, and the Wei soldiers relied on the advantage of numbers, gathered nearly 5,000 sword and shield men, formed dozens of phalanxes, and began to charge the Qilin army with wild shouts and shouts.

The Qilin army stood still like a solid stone wall, and the two armies collided and quickly began to fight each other hand-to-hand, and the entire battle line was suddenly filled with shouts of killing, and blood began to trickle down the place where the two armies were fighting like a stream.

The Hun archers of the Shu army on both sides of the battle line quickly withdrew from the battlefield from the gap specially set aside by the Xiliang Iron Cavalry, and when the pikemen rushed to the front, they were faced with the Xiliang Iron Cavalry of the Shu Army who had formed a dense charging formation.

The pikemen of the Wei army were suddenly a little overwhelmed, only the officers in the queue kept shouting and driving the Wei pikemen in the whole formation, and they wanted to form a phalanx of spears to attack the Xiliang iron cavalry of the Shu army.

Before the Wei army could attack, there was a terrible horn sound from the Shu army. Immediately, the Xiliang iron cavalry on both flanks began to charge towards the pikemen.

As the horses charged collectively, their footsteps became faster and faster, forming an unstoppable momentum, like a flood of water, rushing towards the pikemen.

At this moment, the pikemen of the Wei army, just after chasing the archers and cavalry, experienced a fierce battle, at this moment the physical strength has dropped seriously, and before they can form a front, they suddenly faced the cavalry assault of the Shu army, and suddenly confused, and retreated behind them in horror.

The Xiliang Iron Cavalry of the Shu army was like an iron plow, quickly breaking through the line of the Wei army's pikemen, easily smashing into the Wei army's pikemen, and wantonly slashing and killing the Wei soldiers in the not dense pikemen formation.

The pikemen of the Wei army collapsed in an instant, and fled desperately towards the mountain.

The rout of the pikemen caused the two wings of the Wei saber and shield soldiers to lose the protection of the pikemen, and they were directly exposed to the front of the Shu army's Xiliang iron cavalry.

The dense Xiliang Iron Cavalry carried the momentum of thunder, coming from both wings, and the Qilin Army in front of the fearful sword and shield soldiers was like a great wall of steel, which could not be moved at all, and could not be penetrated, and soon, the Wei army sword and shield soldiers phalanx were surrounded on three sides.

The sword and shield soldiers on both wings were the first to collapse, and the infantry had always had an advantage over the cavalry, and the weapons used by the sword and shield soldiers were the standard knives of the Wei army, not long weapons, and they suffered very much in the face of cavalry raids, and the sword and shield phalanx on both wings quickly collapsed.

Then this rout directly triggered a series of collapses, the entire Wei army's front collapsed, and all the soldiers desperately fled towards the mountain, for fear that they would be chased and killed by the Shu cavalry if they ran slowly.

There were so many Wei troops retreating like a tide that Deng Ai couldn't suppress it no matter how much he pressed it, and he could only sigh:

"It seems that tonight's chance to break through has failed, so we can only hold the mountain first, so as not to be surrounded and annihilated by the Shu army tonight!"

So since he couldn't stop it, Deng Ai simply ordered all the soldiers to retreat to the camp in the mountain of Qishan, and sent crossbowmen to shoot at the foot.

After the soldiers under the mountain were able to escape, almost all of them fled up the mountain, and the Shu army under the mountain also tacitly stopped the pursuit.

Ma Dai found Jiang Wei and asked, "General, our army has won a big victory, why not take this opportunity to annihilate the Wei army of Lushan in one fell swoop?" ”

Jiang Wei said with a smile: "Don't be in a hurry, Deng Ai can't escape, the most important thing for us at the moment is to capture Nan'an, besiege Deng Ai, and at the same time guard against the enemy reinforcements in Tianshui, this is like eating a feast, calling for eating one, clamping one, and watching one." ”
