Li Zhe's second battalion finally caught up with the large army and entered the large camp in Kabu. With this merit, the next attack on Kundu finally caught the battle.

Three days later, the large army came to Kundu, and the second battalion also entered the combat sequence.

The army was arrayed in the valley of the river, facing the walls of the city of Kundu. This Kundu connects the ancient city of Balkh to the east and the Central Asian steppe to the north, which is also the main road of the ancient Silk Road, and the only inconvenience for the Song army is that the Kundu city is located in a river valley, and the river valley is narrow, making it difficult for the Song army to expand head-on.

Li Zhe stood in the middle of the formation, and he couldn't see clearly what the situation was like in the front front, so he could only listen to the drums and whistles in the army to accept orders.

The handsome banner of the general Wang Yu stood on the cliff next to him, a big fashion held high.

Ahead of him, invisible to the naked eye, gunners and artillery were concentrating to suppress the walls.

Boom, the cannon roared non-stop, it was the artillery of the Shenwu general in the army who was striking at the enemy city wall.

The Great General Cannon is a series of heavy siege guns of the Song Army, firing projectiles ranging from three catties, five catties to ten catties. The farthest range is more than three or five miles away, the maximum weight is several thousand catties, and it takes four to eight horses to pull it.

Being able to pull such a big thing all the way here shows how powerful the Song army soldiers are.

The power of the Shenwu general's cannon is amazing, every time the cannon hits the city wall, the entire city wall shakes violently, although the rate of fire is extremely slow, and it takes more than a few minutes for each cannon to fire a second shot, but the destructive power is really amazing, hitting the city wall to crack the stone and collapse, and the enemy troops in the city listen to every cannon sound as if experiencing hell.

Wang Yu looked at the battlefield below the mountain with a telescope from the top of the mountain, which was made of glass that was stolen from Florence in Europa by merchants of the Great Song Dynasty a century ago and then popularized in the territory of the Great Song Dynasty.

This European monopoly of glass-making technology has long been changed into the hands of the skilled craftsmen of the Great Song Dynasty.

In the early years, the price was more than gold, and now the merchants of the Great Song Dynasty made Chinese cabbage, and many middle-sized families can now afford to buy that one-foot square dressing mirror at home, which is most popular with ladies and ladies.

This was far away, and it was back to the point, but it was said that Wang Yu was watching the battle on the top of the mountain with the binoculars, the sharp weapon of the army.

The heavy artillery of the Great Song Dynasty bombarded the city for half an hour without blasting the city wall, which made the senior officers of the Song army, who were accustomed to heavy artillery breaking the city, a little puzzled. Why is it so difficult to break down the wall today?

Wang Yu took the binoculars and carefully observed the place on the city wall that had been hit by cannonballs, for a long time, thoughtfully.

"General, General!"

At this moment a staff officer came up from the bottom of the mountain panting, and came near,

"Report, check clearly, this Kundu city was renovated and rebuilt more than half a year ago, it is said that when the city was built, there were masters of Western Europa who were invited by the Khan King from Constantinople to help build this city, and when the city wall was built, I heard that the sacred mud made of the ancient Western method was used, which can not be broken, and it is very hard!"

"What?"

The officers around Wang Yu were all shocked,

The Great Song Dynasty fought with the Khanate, when was it the turn of the people of Constantinople to intervene.

In this life, because of the continued strength of the Great Song Dynasty and the Mongols, they have been suppressing the West Asian region, so that the Ottoman Turkey, which was prominent in history, has no chance to appear.

The Eastern Roman Empire, which was destroyed by the Turks in history, has not fallen, and is still strong at the junction of Asia and Europe.

As far as Li Zhe knows, Turkey here is a branch of blood that was originally destroyed by the Tang Dynasty when the Western Turks were exiled to Europa, and now it is attached to the Ilkhanate, but it is only one of the important thugs of the Ilkhanate in the West to continue to suppress Europe.

On the issue of dealing with the Mongols, the interests of the Eastern Romans and the Song people were the same, and they had a tacit understanding in this regard for many years, and now, the craftsmen of the Eastern Romans came to help the Mongols build cities?

Could it be that this is a new trend?

As one of the most important military chiefs of the Metropolitan Governor's Mansion of King An, Wang Yu had to consider this kind of problem.

However, if the Mongols think that they can keep the city by getting this bullshit Europa's divine mud, it is simply bullshit, and the heavy artillery can't open it, so don't I have any other way to do it?

What childishness!

Let me see how powerful your clay from Eastern Rome really is!

"Shi Xiu!"

"In!"

Wang Yu called out his generals.

"The enemy's city is thick, and my general's cannon can't work, so I'll let you use the collapse method to destroy the city wall, is it feasible?"

"Order!"

Shi Xiu looked resolute, hugged his fists, and strode away.

Hundreds of years ago, black powder began to be popular in the Song army's siege application, in fact, it was to use tunnels to dig into the city wall, and after going to the bottom of the city wall, then bury it with a large number of heavy mines made of black powder, and collapse far away.

If the city wall does not blow up, without it, you only need to do it again, with more medicine, and no matter how strong the city wall is, it will be impossible to resist it.

After Shi Xiu went down, he only heard a drum beat in Dangdang, and saw several teams of shirtless men thrown out in front of the formation, each team was responsible for a digging point, and they began to dig on the spot less than a few dozen meters away from the city wall.

At first glance, these big men are specialized in training earthwork heavy soldiers, with shovels, nail rakes, and pickaxes in their hands, and a group of people divide labor and cooperate, one after another, and the efficiency is extremely efficient, and in just a few minutes, a pit with a meter square appears in front of the position.

When the observation posts in the city saw this, they panicked.

"Collapse, the Song people want to collapse!"

How can you forget the horror of this collapse method after dealing with the Song people for hundreds of years, and you can know the Song army's intentions at first sight.

Immediately, the city gate was released, and a team of elite horsemen with scimitars rushed out! Wanted to stop the excavation of the Song army.

It's just that since the Song army has been ready for battle, how can they let their attempt succeed.

There were already dozens of sub-mother cannons blocking the front of the formation, and there was a wild bombardment, and the people who rushed out were turned on their backs. Then a neat line of spearmen pressed over, crushing the enemy cavalry under the walls.

There were also firecrackers and archers on the city wall, wanting to support the city wall, but the firecrackers of the Song army on the city wall had been preparing for a long time, and when they landed, the bullets rained down, causing the rubble on the city wall to fly, and suppressed the wall in a blink of an eye.

Hu on the city of Kundu jumped to his feet, but he had no choice but to watch the tunnels of the Song army under the city extend rapidly underground.

In a short time, the tunnel was already dug under the city wall, and some gunners planted explosives, and then under the silent gaze of tens of thousands of people in the whole army, there was a bang! The entire city wall of a few tens of meters flew into the sky!

The Song army, which had been prepared for a long time under the city, shouted, and rushed into the smoke of gunpowder, and the guns and cannons inside were loud, and the city of Kundu was broken!
