Extreme anger made the Qarlu Khan Amit almost crazy, they came all the way, the assassination department was full of devastation, the young and strong men were almost killed, only women, children and old people were left, and the assassination headquarters was looted, the wealth accumulated for decades and thousands of Qarluq nobles were captured by the Tang army, and more than 3 million cattle, sheep and horses in the headquarters were robbed.

An aristocratic old man from Qarluq cried to Amit: "They are so ruthless, all the young men have been killed, all the belongings and cattle and sheep have been robbed, Khan, we are going to exterminate the clan, let's go!" Let's go west! Get out of here, it's too dangerous here. ”

Amit clenched his fists, his teeth clenched, "Blood and hatred, how can you leave?" I will make a big tent out of their human skins, and I will not take revenge on them, and I will not be a man!" ”

Amit turned on his horse and shouted, "Go and gather all the armies, build siege weapons, capture Shattered Leaf City, and raze it to the ground!" ”

'Woo-' The continuous sound of trumpets sounded, and hundreds of soldiers rushed to the various tribes of Qarluq, armed with wolf heads.

This is a tragic massacre that Qarlu has never encountered since the founding of the country, and only by annihilating the Tang army with the strength of the whole country can we avenge the dead clansmen and wash away this shame in blood.

Guo Song stood on the city wall, looking at the Qarluq army in the distance and setting up a large camp, at this time, a soldier rushed over and presented a letter to Guo Song, "Envoy Qi, this is an urgent message sent by Commander Zhang!" ”

Zhang Yun led three hundred scouts to operate on the periphery to understand the movements of the enemy army, Guo Song took the letter, opened it and looked at it, and said to several generals next to him: "Ge Lulu is transferring troops in various places to deal with us with the strength of the whole country. ”

Luo Daxiao's eyes widened and said, "There is still such a good thing? I was afraid that we would not have enough to eat, so I sent it to the door in more quantities, saving us from going around to find them. ”

Everyone laughed, and Guo Song also smiled: "Your commander is too light on the enemy, I still want you to be the governor of Broken Leaves, now I have to reconsider." ”

Luo Daxiao was startled, and hurriedly explained: "It's just a joke, there is no underestimation of the enemy, so don't reconsider it." ”

"What are you anxious about, I'm just kidding!"

........

In the next few days, the Tang army was actively preparing for war, and the regimental training army in the city also lived up to Guo Song's expectations, and more than 500 Qarlu people were searched, who were linked by a Qarluq official in the city, secretly equipped with a large number of weapons, and prepared to cooperate with the Qarlu army to capture the city.

Guo Song ordered that all of the more than 500 Qarlu Neiying be killed and this hidden danger was removed.

Although the Broken Leaf River flowed from the east of the city, there was no moat in Broken Leaf City, so the Tang army temporarily installed two moat drawbridges and dug a deep ravine in front of the city gate.

The walls were tall and strong, but they were not easy to defend and difficult to attack, the north and west sides were flat grasslands, the Broken Leaf River was on the east side of the city, forming an obstacle and could not be placed on the battlefield, and the south was a gravel field, which was not convenient for siege battles.

It was almost certain that the Qarluqs would attack the city from both the north and the west.

In the southeast corner of Broken Leaf City, the Tang Army opened up an equipment field, hundreds of Tang Army and Broken Leaf City craftsmen are reassembling heavy trebuchets, these heavy trebuchets were found in the Broken Leaf warehouse, and hundreds of siege ladders were also found, the siege ladder Tang Army did not need it for the time being, but the heavy trebuchet was the most urgently needed weapon for the Tang Army to defend the city.

The materials used for Gelulu's heavy trebuchets were good, but the assembly was very rough, and they would collapse after a few uses, and the reliability was too poor, so the Tang army needed to reassemble all thirty heavy trebuchets to improve their reliability and ensure that they would not be damaged at least ten times.

The size of this heavy trebuchet is very large, the base is one zhang wide, three zhang long, up to three zhang, and the broken leaf city wall is level, the long throwing rod is ten zhang, and the 100 catties of heavy objects can be thrown 200 steps away.

Such a large trebuchet could not be installed at the head of the city, but could only be placed under the city, but the trebuchet had a large wooden wheel on the chassis, which could be pulled by the oxen and moved slowly according to the enemy's attacking position.

The Tang army built a warehouse with big bluestone under the four city walls, and a large number of arrows, oil and iron fire thunder were stacked in the warehouse, this was the first time that the iron fire thunder went to the battlefield, the Tang army carried a total of 500 iron fire thunders to the west, including 200 large iron fire mines, 300 small iron fire mines, 50 small iron fire mines were left in Jinman County and Yiwu County, and the remaining 400 iron fire mines were taken to the broken leaf by the Tang army.

Iron fire and thunder were all placed in wooden boxes, neatly stacked in four warehouses, this was the first time that the Tang army used such a powerful killing weapon, and it was extremely cautious.

Guo Song was inspecting the warehouse under the North City, and Li Bing asked a little puzzled: "I am a little confused, since the big iron fire thunder is more powerful, then why not cast all the large iron fire thunder, what is the point of the small fire thunder?" ”

Guo Song smiled slightly: "Think about it, if the enemy army under the city is dense, and a large iron fire thunder is thrown down, it will blow up very coolly, but what about the city wall?" ”

Li Bing patted his forehead and said with a dumb smile: "I didn't think about it thoroughly, I forgot to kill three thousand enemies, and I lost eight hundred!" ”

At this time, there was a sudden sound of horns in the distance, and Guo Song smiled: "It seems that there is movement, go to the city and take a look!" ”

When they went up to the northern city wall, they saw in the distance a mile-long Qarluq cavalry was galloping towards them, carrying the banner of Qarluq's black background and golden wolf's head, and there were thousands of them.

Although this was only the first one, it was significant, as it meant that the reinforcements summoned by Qarlu had finally arrived.

For three days, more and more reinforcements came from various pastures, they were herdsmen, they were usually herdsmen, and when they received the call for war, they put on their armor and went to war.

On the tenth day of the wolf's head order, an army of 100,000 Qarlu came from all directions, bringing the total strength of Qarlu outside the city of Broken Leaves to 130,000, and the big tent stretched from outside the northern city to outside the west city, which was very spectacular.

At the same time, Qarluq craftsmen built more than 700 siege ladders, and everything was ready.

In the early morning of this day, the dull sound of war drums sounded in the Qarlu camp, and the horns of the expedition sounded one after another, and the alarm bell sounded urgently at the head of the Broken Leaf City, 'Dang! While! While! '

Countless Tang soldiers rushed to the city from under the city walls, each soldier had his own position, Guo Song threw 5,000 troops in the north and west cities, 1,500 troops in the east and south cities, and 3,000 regiments trained as logistical support, they were responsible for maneuvering trebuchets and transporting supplies up the city, carrying wounded soldiers down the city.

Another 6,000 cavalry were assembled under the northern and western cities, waiting for the order to attack.

On the first day, the Qarluq Khan invested 60,000 troops to attack the city, 30,000 in the north and 30,000 in the west of the city, and the Qarluq Khan also knew that the herdsmen's army was weak in siege and could not capture Broken Leaf City alone, so he added 10,000 direct troops to each of the two siege armies, and let them lead the army to attack the city.

Qarluq Khan Amit stared at the city of Broken Leaves, three miles away, and he waved his sword, "Siege!" ”

'Boom! Boom! Boom! ’

'Woo-' a low horn resounded across the field.

The 60,000-strong army carried 600 siege ladders to advance towards Shattered Leaf City, and they were like black waves, advancing in rows, and the banner of the golden wolf's head on a black background was overwhelming.

At the head of the city, the Tang soldiers stretched their bows and arrows, and waited for the battle, and the thirty heavy trebuchets at the head of the city stood in the north and west of the city respectively, dozens of soldiers pushed the winch like a grinder, and in the sound of 'squeak', the long throwing rod was forcibly pressed down, and the three soldiers lifted a large iron fire mine weighing one hundred and fifty pounds and placed it in a huge iron throwing pocket.

Theoretically, a heavy trebuchet could throw such a large iron fire mine a hundred and fifty paces away, but what kind of consequences and effects it would have, no one knows now.

The soldiers of the firearms battalion have undergone strict training, and they must receive orders from the commander-in-chief to fire iron fire mines, and they must not ignite and fire them without authorization.

The sound of war drums outside the city suddenly became urgent, and the 60,000 Qarlu army outside the city shouted like a tsunami, changing from walking in line to running, rushing towards Shattered Leaf City.

Guo Song looked coldly at the Qarlu soldiers who were getting closer and closer, they had already rushed within a hundred steps, although the iron fire thunder could be launched, but now the launch could not produce the best killing effect, only when the enemy army pressed up, it was the best time to launch.

Guo Song ordered in a deep voice: "Archery!" ”
