At the first watch, most of the defenders in the city fell asleep, only a very small number of soldiers patrolled back and forth at the head of the city, the Sui army has besieged the city for ten days, and has not launched a siege, the soldiers defending the city are gradually tired, inertia, and the soldiers defending the city can see clearly, the Sui army did not make any large siege engines, only a lot of wood was transported, but the shadow of the siege engines is gone, according to this progress, five or six days later may not be able to cause ladders or trebuchets, and their reinforcements are coming.

It was this kind of fatigue and luck mentality that made the defense at night particularly lax...... "Most of the garrisons hid in the city to sleep, and even the officers did not bother to ask, and the sweltering heat caused the physical strength to drop greatly, and everyone seized the time to rest and recover the physical strength that had been exhausted during the day."

In the eastern and western cities, the number of soldiers patrolling at night was reduced from the initial 500 to more than 100, while in the northern and southern cities where the Sui army did not deploy an attack, it was difficult to see a single patrol soldier on the city wall.

The sky was overcast, the clouds were thick, there was no starlight or moonlight, the night was pitch black, nothing could be seen from a few dozen paces away, and there was only endless darkness outside the city.

The soldiers guarding the northern city could not see or think that at this time, the trench a hundred steps away was densely packed with Sui soldiers with bows and crossbows, there were tens of thousands of people, and soldiers were still pouring out of the tunnels, these 10,000 crossbowmen were used as cover, commanded by the general Qin Qiong, and the four thousand heavily armored Modao infantry led by Yang Sien were in charge of the siege, and they were also sitting in the trench waiting for the moment of attack.

In the middle of a group of heavy armored infantry, there is a five zhang long, more than three feet in diameter of the ramming ram, this ramming ram is made of a girder of Jinyang Palace, it is a thousand-year-old iron wood harvested from Yuzhang County, weighing thousands of catties, the front end is equipped with a stainless steel ramper, and the lower end of both sides is equipped with two hundred grippers, and two hundred heavy armored infantry must be used to lift it.

Although the trench was crowded with fourteen thousand people, not a single one spoke, the trench was silent, even if someone could not help coughing, he would lower his head, cover his mouth with his hand, and try not to make a sound, the only thing that bothered the soldiers was the mosquitoes, which were hot and humid, and a large number of mosquitoes bitten the soldiers, so that they kept driving away these disgusting vampires with sweat cloths.

Two miles away, 30,000 cavalrymen were already lined up, their spears held high, their swords unsheathed, and they stared at the northern city with cold eyes, waiting for the moment when the city gate opened.

The time gradually came to a watch, the time for the siege of the city came, fifteen black shadows moved unusually fast to the north city gate, more than ten thousand pairs of eyes stared at them, this is fifteen scouts with high martial arts, they used long planks to build the moat, quickly crossed the river and stuck to the root of the wall, each of them carried three bags of oil on their backs, unloaded the oil from their bodies but did not act in a hurry, two of them climbed the suspension bridge like apes.

The drawbridge was the key to the siege, and only by lowering the drawbridge could the city gate be rammed, but the drawbridge was wide and heavy, with strong planks up to half a foot thick, and two arm-thick iron chains stretched down from the head of the city, firmly holding the drawbridge and dragging it high in the air.

Everything has weaknesses, and this suspension bridge is no exception, its weakness lies in the iron chain that fastens the two iron wedges of the suspension bridge, the iron wedges are deeply inserted into the wooden planks, and a pig iron ring is also tied outside, and holes are punched in the pig iron rings so that the iron wedges pass through the holes, so that even if the wood decays, the iron wedges will not fall off.

However, the North Gate Drawbridge had been worn out of time, and the holes in the iron hoops had been worn out, so it was possible to pull the iron wedge out of the drawbridge, and the Sui scouts discovered this small loophole.

It was this noon detail that made Yang Yuanqing finally decide to attack the North City Gate, perhaps, this is called the Sniper Festival to decide success or failure!

The two scouts climbed the drawbridge, they used a short iron rod to slowly pry the hoop, the hoop moved up a little bit, out of the iron wedge, without the support of the hoop, the two iron wedges could not hold the heavy drawbridge, made a creak, the drawbridge shook slightly.

As soon as the two scouts turned over, they got under the drawbridge, hooked the drawbridge with their feet, and took out the bright saw, one scout turned around and made a gesture to signal that the others could move, and the other thirteen scouts slowly poured the oil from the gap at the lower end of the gate, and a wooden board blocked them from flowing out, and the oil flowed into the city along the gap.

At the same time, the two scouts under the drawbridge gradually sawed a crack in the planks on the edge of the iron wedge, and the cracks appeared so that the iron wedge could no longer hold the heavy drawbridge, 'Boom! There was a loud bang, the iron wedge on the left came out, the long, thick iron chain flew into the sky like a long snake, and the drawbridge tilted to the left.

The loud sound of the drawbridge tilting alarmed the defenders of the city, "Who is it!" One of the defenders came out to watch, but a poisonous crossbow arrow shot like lightning, the defender snorted, and fell softly on the battlement, but he did not expect that there was another person behind him, he saw that his companion was shot dead, and shouted in shock, "Come on!" ”

At the shout, the chain on the right also flew into the sky, followed by 'Boom! There was a muffled thud on the ground, and the drawbridge landed heavily on the moat, making a big splash.

The fall of the drawbridge was the signal, and two hundred heavy infantry moved the ramshell out of the trench, with a hundred people standing on each side, two layers in front and two, holding the handle of the hammer with both hands, and two hundred heavy infantry raised huge shields to cover.

Like a giant hundred-legged worm, the hammer began to rush towards the gates, when the alarm bell on the city wall rang, 'Dang! While! While! It was so harsh that tens of thousands of defenders sleeping on the head of the city were awakened, and they rushed to the city.

The chief officer on duty at the head of the city tonight was Liu Zhenghui, the commander of the guard, and he already understood that something was wrong, the Fengzhou army launched an attack at night, and he was so anxious that he shouted: "Hurry up and report to General Xiahou!" ”

Liu Zhenghui ran to the city wall, and was about to look down, when an arrow flew whistling and grazed his forehead, startling him into a cold sweat, he hurriedly turned around and shouted: "Trebuchet throw!" ”

"Envoy, you can't see it outside!"

"if you can't see it!"

Trebuchets creaked apart, and in the darkness the soldiers could not see what was happening outside the city, and boulders flew out and smashed aimlessly.

More than 1,000 crossbowmen rushed to the edge of the battlements, to be suppressed by the overwhelming arrows, and could not lean out to shoot at all, at this time, the crossbowmen of the Sui army of Wanfengzhou under the city formed an arrow array, and ten thousand arrows were fired together, covering the heavy infantry to hit the city.

A raging fire has been lit in the city gate, the tongue of fire is burning the gate wrapped in iron sheets, the entire city cave is engulfed in fire and smoke, so that the defenders dare not take a step closer to the city gate, Xiahou Duan has arrived, his face is unusually pale, and he has become a little distorted due to nervousness, he has realized the seriousness of the problem, Fengzhou did not beat the drum, did not blow the trumpet, and attacked silently at night, it is very likely that Taiyuan City will be lost today, he immediately shouted: "Quickly adjust five thousand crossbowmen to the north city gate!" ”

As soon as the words fell, an earth-shattering loud noise came from the city gate, the dull and strong impact sound of "boom one by one" seemed to come to hell, directly hit people's hearts, and made people's hearts seem to be broken, many soldiers couldn't stand this impact, covered their ears and screamed to the ground, the whole northern city was shaking, the soldiers screamed in horror, squatted down one after another, a trebuchet tilted, lost its center of gravity, and slowly fell from the city, breaking into several pieces.

The shaking of his feet caused Xiahou Duan to fall to the ground, and he got up and shouted anxiously: "Go and adjust the crossbowman!" Just go! ”

Outside the northern city, hundreds of heavy armored infantry slowly retreated with rams, holding hundreds of huge shields above their heads, although the bow and arrow could not shoot them, and the boulders were thrown from the city, there were still many heavy armored infantry who were hit, fell to the ground with a muffled scream, and were immediately dragged down by the soldiers next to them......

Yang Sien, the commander of the heavily armored Mo Sword Army, was also beside the ramshell, and when everyone retreated twenty steps away and began to prepare for the second impact, he shouted loudly: "One! Two! Three! ”

Hundreds of soldiers exerted force at the same time, and the ram hit the city gate again with an incomparably fierce force, only to hear another earth-shattering loud noise, the city gate shook violently, and the latch behind it was about to be broken, and the masonry on the gate was loose and fell down one after another, and huge cracks appeared in the city wall next to it.

"Come again!"

Yang Sien roared, the team retreated again, retreating to more than twenty steps away, hundreds of heavy armored infantry roared in unison, they poured all their strength, hugged the ramming ram and rushed towards the city gate again, the power bursting from the ramming ram seemed to be able to destroy even the mountain.

Not long after the drawbridge collapsed, Taiyuan City has begun to be in chaos, the Xue brothers led hundreds of people to rush to the outside of the barracks, set fire to the barracks, hundreds of camp tents were set on fire, the barracks were already in chaos, the horse circle was also opened, thousands of war horses rushed out of the horse pen, running on the street, the Xue brothers' subordinates ran up to grab the horses, and did not care about killing the enemy and making meritorious contributions.

The Xue brothers wanted to catch Li Wuji, and led more than 100 people to run towards the governor's mansion, but they just ran to the governor's mansion, but they greeted Changshi Dou Dan on horseback and rushed over, and there were less than ten guards around them.

Xue Shen was overjoyed and shouted, and more than 100 people rushed up, overturned Dou Dan to the ground, and tied him up, at this time, one of his subordinates rushed to shout: "Big brother, Li Wuji led the army to the south gate." ”

Xue Shen hesitated, since Li Wuji had an army in his hands, it would be difficult to fight hard, but burning down the barracks, letting go of the war horses, and catching Li Yuan's son-in-law, these are all credits, he saw a group of soldiers in the distance running towards this side, so he waved his hand, and everyone grabbed Gu Dan and ran towards an alley, and soon disappeared into the darkness.

On the streets of Taiyuan City: chaotic, full of soldiers, the fire has engulfed the barracks, the soldiers can't find the team, they are running aimlessly, many soldiers began to take the opportunity to smash the shops and loot.

When the first sound of hitting the city came, Li Wuji and Yu Wenshu led three thousand cavalry at the south gate, the south gate was slowly opening, Li Wuji was flustered, although he should stay to command the last defense of Taiyuan, but he had completely abandoned Taiyuan City, he now only had one idea, to escape Taiyuan City as quickly as possible.

"Qi Gong go slowly!"

Sima Liu Dewei chased after him, he stopped Li Wuji, and said hurriedly: "Now is the most critical time, if Duke Qi escapes, the army's morale will be weakened, and Taiyuan will really be finished." ”

Li Wuji glared, "Who said I was going to escape, I was going around to attack Yang Yuanqing's camp and force them to retreat, you dare to ruin my plan?" ”

Li Wuji used a long lance to pull away Liu Dewei's horses, whipped the horses, and led 3,000 people to rush out of the city, Liu Dewei turned over and dismounted, and ran towards the city, he stood on the city wall, Li Yuanqing's cavalry had disappeared into the darkness, but he faintly heard the sound of horses' hooves heading south, Liu Dewei sighed, Li Wuji still escaped.

The third fierce impact of the Fengzhou army finally broke the latch of the city gate, and the north gate of Taiyuan was smashed open, and the thousands of heavily armored Mo knives behind shouted and rushed towards the city, and the dense rain of arrows shot at them, but they could not penetrate their armor, and they raised the snowy Mo knife to rush towards thousands of soldiers.

Two miles away, Yang Yuanqing saw that the north gate had been knocked open, and he waved his war knife and shouted: "Kill into the city!" ”

"Kill!"

30,000 cavalry launched and rushed towards Taiyuan City.
