The crossbow on the northwest corner also fired an arrow, but this time the accuracy was not good, and the rocket flew over a few feet away from the looking building.

But it is no longer possible to rest assured to the lookouts on the tower.

It turned out that the accurate stone bomb shooting gradually began to lose its accuracy. The Song army's accurate head in the city was getting higher and higher.

The fence originally built in front of the Mongolian cannon cart was almost wiped out by stone bullets, and the curtains were burned by fire. The whirlwind cannon cart could suppress some of the city guards exposed. The three-pound mud ball was completely harmless to the high-rise battle shed on the village wall. The lookout hand of the Tulong Army could safely hide inside and continue to observe until the gun cart on its own side completely destroyed the target.

The Mongolian gunners began to shift the fire concentration targets in a hurry, trying to concentrate their firepower on the two corner tower platforms to destroy the crossbows. However, the stone thrower's accurate head was not as accurate as the crossbows, and there were war sheds above both bows and crossbows, so it would be fine if they were hit by a stone bullet.

During the melee, four three-bow crossbow rockets launched one after another, and soon hit the other two towers.

The balance of victory began to tilt towards the defenders.

"Come on, let's see what Shi Tianze, who is famous in the world, has real skills." Yang Xuan murmured, and waved his hand to let the husband under the city start to pull the strings.

Unexpectedly, a rushing gong sound came from the direction of the Mongolian camp.

Advance and retreat when hearing the drum and retreat when hearing the gold is a traditional order for the Central Plains to fight. There was no such set on the grassland, but most of the powerful people in the Central Plains and Liaodong followed the old rules. Moreover, this effective signal system was reversed into the real Mongolian army, and drummers and gong players were also started to be organized in the standard Mongolian light cavalry team.

"The enemy wants to retreat?" Ma Xiang poked his head out from behind the horse's card in surprise and watched the Mongolian soldiers on the stone throwing machine's position start to retreat one after another.

He turned his head and asked Lu Xunzhi on his seat, "Direction, can they really not be able to hold on?"

Lu Xunzhi shook his head and did not speak. He just silently looked at the orderly retreating team in the distance.

When Lu Xunzhi got off the horse road, he happened to meet Yang Xuan holding a jar of fine wine and was joking with a group of crossbowmen in bed excitedly.

"Constitution!" Yang Xuan, who saw Lu Xunzhi walking over, hurriedly poured a bowl of wine and brought it forward: "Today's first battle, I have worked hard to command the commander of the first battle. Come and drink this bowl of yellow oranges. This is a wine made of Dongting honey oranges, a unique Jinghu wine."

Lu Xunzhi reached out to block the bowl of wine.

"Don't you think there is any difference between today's victory and the day before yesterday?"

Yang Shu lowered his head and thought for a while, saying, "Apart from normal casualties, the cheers after the end were lowered."

"That's right," Lu Xunzhi pointed to the wall of the village and said, "This is why Shi Tianze gave up so easily today."

Only then did Yang Yu realize that there were tired and powerless faces under the city wall.

Many people were sitting on the ground and gasping for breath, while others simply lay down on the ground. The people standing were sweating all over their faces and their hands and feet were shaking slightly.

The strength of the entire army has reached a point where it is about to be exhausted.

"They have not really decided to retreat, they are preparing to regroup." Lu Xunzhi said calmly: "Shi Tianze has exhausted our army's physical strength, and the next is a truly violent blow."

"They will dispatch siege troops to wipe out our tired army in one fell swoop."

Yang Xuan then realized why Lu Xunzhi insisted on requisitioning the strong men from the parody to use as gunners to pull ropes before the war was to save the army's physical strength to the greatest extent.

But the tyrants had not been trained, so each cannon carriage had to arrange some soldiers to take the lead in pulling the ropes, otherwise they would not be able to compete with the Mongolian cannon carriages for so long.

In this way, the physical strength of thousands of soldiers was completely exhausted. This is not the archers who had just fought against the Mongols.

The two thousand defenders have too few troops!

Yang Xuan smashed the wine jar to the ground: "I didn't notice this at all!"

"On the contrary, Shi Tianze knows this very clearly." He gritted his teeth and said, "He has an absolute advantage in military strength, but he always only used a part of his people to engage in artillery battles with our army, because he deeply understood that behind each cannon car is manpower, with dozens of people and hundreds of people. He only uses one or two thousand soldiers and a sufficient number of civilians to force us to use the same number of manpower to fight with him. Regardless of success or failure, our army's physical strength will inevitably be exhausted."

"And he still has enough new horses in his hand!"

"It's useless to say more." Lu Xunzhi shook his head and said, "Carry out the last five hundred new forces prepared in the camp, organize Zhuangdeng to go to the city to replace the exhausted sergeant's storefront, so that the soldiers can seize the last time to recover their physical strength."

"The only thing left is to be left to fate."

Without a stick of incense, the horns of the Mongolian military camp sounded one after another. The leader's crooked horse team rushed out first and occupied the periphery of the three village gates. This was to avoid the military and civilians escaping from other directions after the city was broken.

The following were the brigades of iron-armored cavalry, with bright armored helmets and bright armor, arranged in neatly under the flag, and advanced towards the north gate of Dazhai with slow and solid steps.

Behind them were the siege soldiers of a large siege. At the front of the queue were the First Ding soldiers wearing armor. During countless siege operations in the north, these soldiers danced long spears in their hands, held sharp armor, and fought bloody battles with the Jin Dynasty defenders on the city, achieving brilliant results. They were Shi Tianze's most trusted Hejian guards.

Although most of the ordinary infantry following could only cover their bodies with a simple piece of iron armor or leather armor, they were numerous and had no lack of combat experience. When they first entered the army to open a breakthrough, they would rush up to fight with the defenders and win with their number and superb martial arts.

But none of these were enough to surprise Yang Yu. What Yang Yu was surprised was the six goose cars with ladders rising in front of the siege team.

In the earliest siege, the soldiers rushed to the city bravely and used human power to build human ladders to climb up the city wall. Later, they invented a ladder that could overcome the city wall.

However, the archers shooting randomly in the city were still a big threat, so some people came up with a way to build a shelf with wood, covering one or two layers of cowhide or iron, as a cover, and installed wheels underneath, and the soldiers hid in the car and pushed forward. This is the siege weapon cave chariot that is often used in the Central Plains.

The use of cave chariots was not uncommon in the siege battles of the Central Plains, and the manufacturing process was simple and easy to understand. Not only were they used in large numbers when the heroes of the Central Plains competed, but even foreign ethnic groups such as Nanzhao, Tubo, Silla, and Khitan were widely used. The Liao and Jin dynasties were used to attack the solid city walls of the Song Dynasty. After Mongolia advanced south, they captured Jin craftsmen and made large quantities of these cave chariots to attack the capital of the Jin Kingdom Bianliang. Since then, the cave chariots became a conventional weapon for the Mongols to attack the city.

However, there is only one way to attack the city, which is to rush under the enemy's city wall to dig caves and open a path under the thick city wall. However, China's cities have a reputation of indestructibleness. Helian Bobo built Wancheng and used an iron cone gun to test the strength of the city wall. This level of city is actually not uncommon in the Central Plains. Just a few hoes are like making holes in the city wall at will. Wouldn't it be considered a joke to siege the city? In fact, even if soldiers worked under the city wall all day, they might not be able to dig a cave that could hide people, let alone dig through the city wall. In the fierce offensive and defensive battle, it is difficult for the cave car to avoid being destroyed by the defenders for a whole day.

So another craftsman thought, could the cloud ladder and the cave car be combined into one? Most of the risks of using the cloud ladder also come from the distance from the starting position to the city wall. If the cave car is protected, it will be safer to lift the cloud ladder under the city wall. On the other hand, soldiers do not have to dig the soil under the enemy's rolling wood and stones when rushing to the city, and just use the cloud ladder to climb the city.

The cloud ladder was placed on the cave cart, and the upper end of the cloud ladder was tilted forward, and its shape was similar to a goose, so it was named Goose cart.

Shi Tianze wanted to use six goose cars as the vanguard to attack the troops, and be able to seize the city wall in the shortest time, so as to give full play to the Mongolian army's numerical advantage as soon as possible.

Before this, although Shi Tianze fought with Peng Yibin, a Shandong hero who was known as the general of the Song Dynasty, and also met with Li Quan, the general manager of Shandong Military and Horse Capital of the Song Dynasty, these two were actually the remaining troops of the Shandong Red Coat Army and were not considered regular troops of the Southern Dynasty.

He didn't know that in the Song and Jin war, the soldiers and civilians of the Song Dynasty suffered a lot in front of such siege equipment invented by the Han people themselves, and had long summarized a complete set of ways to deal with it.

After the infantry held up regiment signs and leather signs to clear out the road ahead and filled the gully with firewood, dozens of people under each goose carriage with colorful flags pushed slowly towards the north wall of Laoyashan Village.

When the Hejian guards followed the goose cart to General Mu's range, they were greeted with a huge roar and a jet of lead-stone bombs.

It was also the first time that Shi Tianze's elite soldiers performed much better than the Han'er army under King Tasi's subordinates. Although there were chaos and shock and some people tried to escape, most of them still followed the goose cart firmly.

How could a man from Hejian, who roamed North China, be frightened by these fire-breathing bamboo tubes at will!

The archers on the city wall also began to shoot arrows, but as Shi Tianze expected, their physical strength had been consumed, and the arrows they shot were weak and powerless, and they were unable to pose a substantial threat to the armored troops.

When General Mu was ready for the second shot, the goose car was only twenty or thirty steps away from the village wall.

"Don't worry about the big cart first!" Wang Bao, the officer of General Mu's army, shouted: "The more infantry you follow, the better!"

Another burst of lightning and fire bombardment, and many of the armored soldiers of the goose cart fell to the ground.
Chapter completed!
