Two huge iron fire thunderbolts exploded earth-shattering above the heads of the Hui soldiers, and two blazing flames rose into the air, instantly turning into black smoke, and a strong shock wave swung downward, and tens of thousands of dense poisonous nails burst out in all directions, flying hundreds of paces away.

The Hui soldiers were all shocked to death, and the bursting iron pieces and dense and small poisonous nails shot through the leather armor of countless soldiers and shot into their bodies, but the pain of being shot was far less than the fear and sound stimulation of the strong explosion, and the attacking Hui soldiers collapsed instantly, they threw away the siege ladder, shouted in fear, desperately turned around and fled, and the army was defeated like a mountain.

More than 700 people were directly killed by two large iron fire mines, and thousands of people were shot by poisonous nails and pieces of iron, and countless people were shot in the head by pieces of iron and died on the spot.

The main force of the Hui two miles away was also affected by the explosion, the strong explosion made everyone's ears unbearable, the war horses screamed violently, and the prime minister was shocked and shouted: "Retreat ten miles!" ”

20,000 cavalry turned around and fled, for a time like a mountain torrent erupted, the slower was dragged down by the war horses, trampled by the horses and died, 20,000 people ran for their lives, and the defeated soldiers behind also galloped, the drums on the city were like thunder, and the cheers resounded in the sky.

Su Zhen led 500 cavalry out of Guancheng, captured the horses, and killed the wounded enemy soldiers.

.........

More than 20,000 people fled for more than ten miles before they slowly recovered from their panic, and sighed with their hearts up to the sky: "I have always wondered, why were the Qarlu people wiped out by the Tang army in Hexi so quickly? Now I know the reason, they have such a sharp killing weapon, can the Qarluq people be undefeated? ”

Wanfu Changsu Muda said in a low voice: "Prime Minister, something is not right?" ”

"What's going on?"

"I counted it just now, why are there only 25,000 people who have escaped?"

Chi Xin was also stunned, it was impossible to kill 5,000 people at once!

He immediately ordered, "Let the spies go back and check, what's the matter?" ”

More than 100 spies galloped away on horseback, and half an hour later, a spy came with the news, thousands of soldiers fell on the way, killed by the Tang cavalry who came out of the city, we rescued some soldiers, but none of them survived, they showed symptoms of poisoning, they themselves described, they were shot into the body by a secret weapon such as a poison nail or a stinger.

Chixin immediately understood that it must be explosives mixed with a large number of poisonous nails, and he gritted his teeth with hatred: "Damn bastard!" ”

In his memory, no Tang army would be so vicious, and at this time, all the generals looked at him and waited for his decision.

Chi Xin said slowly: "Running after poisoning, once the poison gas attacks the heart, it will be difficult for the gods to be saved, so let's protect the main force!" Pass my order and retreat north to the steppe. ”

Everyone understood, the commander gave up the wounded soldiers, but no one objected to the decision of the red heart, they were all frightened by the Tang army's big killer, and the idea of going south to loot Taiyuan had long been lost, and the generals gathered their soldiers one after another and evacuated to the north.......

The Hexi army that fought out of Loufu Pass gained a lot, they captured more than 4,700 war horses, more than 2,000 wounded enemy soldiers were killed by them, two large iron fire mines exploded in the densest place of the crowd, although more than 700 people were killed on the spot, nearly 600 people were shot in the head by iron pieces and died, and more than 300 people trampled to death when retreating.

However, most of the dead were shot by poison nails, and the poison spread rapidly throughout the body during the run, and finally died of poison gas, and many soldiers did not die for a while, but finally died under the spears of the Tang cavalry.

This is a classic firearms strike war, the first time Hui encountered a powerful firearm, the whole morale and military spirit collapsed in an instant, fear made them fall into madness, and running for their lives became instinct.

It is a pity that the Tang army at Lou Fu Pass does not have many troops, otherwise it will take advantage of the victory to pursue and completely defeat the Hui army.

The 25,000 Hui cavalry retreated north in panic, and simply rested for two hours at night, before dawn, the Hui army hurriedly set off north, bypassing Shanyang County and Mayi County, and arrived at the Lahe Valley at noon, half a year ago, the 3,000 Hui soldiers were wiped out here.

However, the traces of the war have long since disappeared, and the Hui army in front of them does not know what happened here half a year ago?

The Lahe valley is about ten miles long, about 100 zhang wide on average, on both sides is a gentle slope, the slope is lush with woods, but in the narrowest place it is only a few zhang wide, and the cliffs on both sides are just a bend.

The 25,000 Hui army entered the canyon in a mighty way, just in the woods on the hillside, Guo Song looked coldly at the Hui army below, he turned around and ordered: "Order the heavy infantry to move!" ”

2,500 heavily armored infantry quickly dispatched and rushed to the south of the Lahe Valley, cutting off the southern retreat from the valley.

At the same time, three thousand crossbowmen and two thousand spearmen were arranged to the northernmost part of the valley.

The forward of the Hui people gradually entered the narrowest place, and at this moment, seven or eight large iron fire thunders were thrown on the top of the cliff in a row, and before the Hui soldiers below could react, the iron fire thunder exploded in a series of explosions in the valley.

The continuous violent explosions were like a landslide and the ground cracked, blood and flesh flew everywhere, and the screams were terrible, almost all the Hui soldiers were frightened, and when they reacted, the soldiers turned around, shouted loudly, and fled for their lives to the south desperately, they had been frightened by the Tang army's big killers.

'Woo! ’

Horns sounded on the slopes on both sides, and more than 20,000 Tang troops from Hexi came out of the woods on the hillside, and the arrows shot like a storm towards the chaotic Hui army below, and large areas of the Hui soldiers were shot down.

Guo Song waved his sword, "Kill!" ”

"Kill—"

223,000 Tang cavalry were killed, and the chaotic Hui army was cut into countless sections, and the Tang army was well-trained and fought in a very disciplined manner, and they took 100 people as a team to mercilessly kill the Hui soldiers in the chaos.

Chi Xin was well aware of the danger of the situation in front of him, and if he continued to fight like this, the Hui army would be wiped out, and he must withdraw, and he shouted with all his might: "Break through to the south!" Break out! ”

Thousands of Hui cavalry in the south desperately broke through, but they were intercepted by 2,500 Modao troops, who were like an iron wall, wielding sharp long knives and cutting the enemy cavalry that kept rushing up to pieces.

The corpses in front of them were piled up, and the valley was filled with a pungent smell of blood and viscera, and although more than 3,000 Hui cavalry were killed, the cavalry that broke through still rushed forward in waves.

There were also many cavalry in the north who tried to break through, but the narrow passage restricted the large cavalry from rushing out, and on the opposite side were 3,000 crossbowmen, but whenever a cavalry ran out, they were killed by random arrows, and the horses were not spared.

The battle lasted from noon to dark, and the meat grinder-like war finally came to an end.

The fierce battle has ended, thousands of Tang soldiers are busy cleaning up the battlefield, this battle, the Hui army is almost completely annihilated, 25,000 people died in the Lahe Valley, but the Hexi army also paid a lot of price, nearly 5,000 casualties, although only 20% of the enemy's army, but also a rare heavy loss in recent years.

At this time, Li Bing walked over quickly and said, "Envoy Qiqi, I have discovered the whereabouts of the enemy commander." ”

This is where Guo Song is very puzzled, combing through it several times, but he did not find the body of the enemy commander Chixin, and his own soldiers did not find it, obviously he fled, but where did he escape, Guo Song did not figure this out.

"Where is he?" Guo Song asked anxiously.

Li Bingyi pointed to the woods in the southwest direction and said: "He led more than a thousand people to flee into the woods from there, walked south from the woods, bypassed the heavy infantry and was discovered by the scouts on the periphery, but they still broke through." ”

Guo Song became more and more puzzled, "If you go south, it should be a cliff, and the heavy infantry is at the mouth of the cliff, how can they get around." ”

Li Bing smiled bitterly and said, "The corpses became an obstacle for the heavy infantry and they continued to advance forward, advancing a total of two hundred steps, and the result was that these two hundred steps left a gap, causing them to flee from the edge of the cliff. ”

Only then did Guo Song realize that the battlefield was constantly changing, and the defense should also judge the situation to adapt to the changes, and he would respond to all changes with the same, more or less carving a boat.

Guo Song said helplessly: "Where did they flee?" ”

"They should have withdrawn from Yangmayu to the west."

Yangmayu is a very wide valley eighty miles to the west, and it is much safer to go there than here, but it is a long way to detour about two hundred miles, and the Hui army did not have enough food to support it, so they chose the Lahe Valley, and finally the whole army was destroyed.

Chixin led more than a thousand of his subordinates to gallop all the way in the dark night, and entered Yangmayu at dawn.

Although the Tang army surrounded the Hui army without leakage, it was still found a loophole by the prime minister Chixin, who led more than 1,000 cavalry to break through into the woods, bypassing the blockade of the heavy infantry from the woods, and escaping Shengtian.

The 1,000-year-old cavalry quickly whipped their horses and did not dare to stop for a moment, and fled to the nearest northwest steppe.
