Yelu Dagu was too full of words in front of the local clan leaders such as Magutou last night, although he saw that the walls of Shuitou City had increased by nearly half, and the walls were cold and slippery, and hard as stones, which was very unfavorable for the siege, but he still ordered the siege with a gritted tooth.

Yelu Dagu led the Xijing army to attack the city, like the sprint of the Khitan iron cavalry, just three words - hard hit.

Seeing that the Xijing army of the Liao State was also this method of attacking the city, this made Zhang Bin breathe a long sigh of relief, especially watching the Liao army carrying ladders and climbing the ice wall being easily killed or beaten down by the soldiers, and soon there were four or five hundred corpses of Liao people under the city, Zhang Bin was completely relieved.

If the Liao people always only had this method of siege, all he needed to consider was the problem of food and arrows.

But soon after the Xijing Army of the Liao State launched more than 100 stone throwing machines, Zhang Bin's expression became solemn.

Because these stone throwers look quite exquisite, and the volume is not small, not much worse than the stone throwers built by the Song State Military Weapons Supervisor.

A quarter of the population of Liao is Han Chinese, and the largest number of Han people in Xijing Dao, including the sixteen states of Yanyun, are not surprising to be able to build such a level of stone thrower.

Soon, a terrifying stone and ice bullet smashed towards the head of Shuitou City with a piercing sound of breaking through the air.

The casualties caused by these stone and ice bullets were actually far less than the bows and arrows thrown by the Liao people outside the city to the city, but the psychological fear brought to the defenders of the city was greater than the bow and arrow attack.

Therefore, watching a stone bullet and ice bomb smashing towards the city, including Zhang Bin, many people couldn't help but show fear on their faces, and Zhang Bin was naturally protected by the guards and retreated to a safe place.

Bang bang......

The stone bullets and ice bullets smashed against the ice wall, causing a splash of ice chips, which hit the armor of the Song soldiers who had already retreated behind, and there were two or three screams.

"Hahaha......" Zhang Bin couldn't help but be overjoyed, and shouted: "There are more than 100 stone throwing machines of Liao thieves, only three stone bullets fell on the city head, and four stone bullets smashed on the city wall, this accuracy really scared me a lot........."

Zhemuqiu said in a timely manner: "The accuracy of the first wave of shooting is generally not high, and after the Liao people adjust, the accuracy will increase." ”

As the two were talking, the second wave of ice bombs and stone bullets of the Liao people flew over again, and compared with just now, there was one more stone bullet that fell on the city, and there was only one more stone bomb that fell on the city wall. Many of them were smashed on the ground outside the city walls.

Because the accuracy of the Liao people's own stone throwing machine is too poor, if the soldiers are allowed to attack the city in the process of the stone throwing machine, there will inevitably be a large number of accidental injuries, so the purpose of the Liao stone throwing machine is to smash the ice wall that Yelu Dagu secretly hates.

Because the Liao soldiers did not rush to the city, Zhi Kerou ordered the defenders to retreat to a safe place in the rear as soon as possible, leaving only a small number of people to hide behind the wall and watch the enemy situation outside.

Zhang Bin secretly calculated the efficiency of the Liao people in smashing the city wall, although as long as the stone bombs and ice bombs bombarded the city wall, it would cause large pieces of ice covering the city wall to fall off, but the Liao people needed to smash it for a whole day before the stone bullets and ice bombs would fall directly on the rammed earth city wall.

And it was just one night, enough time for Su Guo to drive the Liao people in the city to carry water, so that the city wall was rebuilt and nearly half an ice wall was raised, I don't know how the Liao army outside the city felt the next day when they watched Bai busy all day.

Zhang Bin watched the Liao people's game of throwing stone bullets for a while, and then surrounded by a group of guards, he got off the city wall and came to the most heavily guarded area in the city.

The most heavily defended area in Shuitou City was not where Zhang Bin and Zhi Kerou lived, nor was it a military camp, but the cleared open space in the center of the city. In addition to being guarded by Han Saburo with nearly a hundred people from the pacification division, there were also 500 soldiers on the periphery who surrounded the place.

In addition to the five hundred catties of black powder that have been reformulated these days, there are also a hundred barrels of light fire oil that Zhang Bin arranged for Han Saburo to transport with the caravan in advance.

Zhang Bin came here at this time, but he didn't come to see gunpowder and light oil, he came to see some things made by the seven craftsmen who came with Han Saburo's caravan.

These seven craftsmen are not folk craftsmen, but craftsmen of the Great Song Dynasty Weapons Supervisor, who were specially brought by Zhang Bin to Han Saburo from Tokyo City, and have been building various equipment for the Great Song Dynasty military for defending or attacking the city for generations.

When they came, they also brought their tools, which were made from demolished houses in the city.

In addition to the seven craftsmen, all the people who made the utensils were more than 100 Han people in the original caravan, and after ten days of work, seven bed crossbows and 20 stone throwers were built to defend the city.

Zhang Bin came to see the stone thrower, and just now looking at the accuracy of the Liao stone thrower, he suddenly had some ideas.

It is not the first time that Zhang Bin has seen the stone thrower in this era, of course, it is mainly the memory of Zhang Bin before he traveled.

The stone throwing machine in front of him looks not much different from the stone throwing machine of the Liao people outside the city, it is quite simple, the main structure is the throwing rod, and the front part of the throwing rod is connected with a full dozen ropes, but it is not used to tie stones or heavy objects, Zhang Bin knows that this is used for manual pulling, and the stone throwing machine of the Liao people outside the city is also used in this way.

After the seven craftsmen of the Ordnance Supervisor saluted just now, they stood aside, watching the young Supervisor staring at the stone thrower that he and the others had built in a daze, thinking that he had never seen the civil official master so interested in these tools.

They are very confident in their craft, and they have been building such things as stone throwers from generation to generation for many years, so they are not worried that the overseers will check out that the stone throwers are unqualified and so on.

"Tell me how to do it." Although Zhang Bin knew how to operate, he still pointed to the old craftsman in the lead.

Although the old craftsman is very old, and he is also a person with some status in the Ordnance Prison, but in the Great Song Dynasty, except for the emperor, any other profession is not higher than that of a civil official, not to mention that this is in the army, he immediately walked over respectfully and quickly, pointed to the stone throwing machine and said: "Hui Guan, this stone throwing machine is very simple to operate, each of these dozen ropes needs to be pulled by one person, and when the time comes, a unified order, more than a dozen people work together, and the other end of the throwing rod worn on the beam is pulled up, and the stone bullet on it is thrown out." ”

Zhang Bin nodded, without any accidents, and said: "Why do you have to drag so many ropes, so many people use them to pull, the strength is different, the direction will be different, this accuracy is naturally poor, and it is very troublesome to adjust it later, and even because it is pulled by more than a dozen people, there is no way to adjust it." ”

The old craftsman praised from the bottom of his heart: "The official is clear, this is indeed the truth. ”
