Seeing Han Heng's expression ugly and despair appeared in his eyes, Shen Pei asked in confusion: "Zi Pei, do you know what the wooden frame outside the city is?"

Han Heng smiled bitterly and said, "Lord, Zhengnan, I also saw the introduction and description of this object from a non-black history by chance. This object is called the 'cattering machine', which is a treasure of the Mo family during the Warring States Period. After the Qin Emperor unified the world, as the Mo family retired to the mountains and forests, the manufacturing process of this object gradually disappeared. During the reign of Emperor Wu, some people also made this cattering machine. However, due to various reasons such as inconvenience in transportation, the size of this cattering machine was not too large, but the cattering machine outside the city was so huge, it is really hard to imagine how the Yang family army transported them from Bingzhou!"

"Ah?" Shen Pei was shocked when she heard this and said, "This thing is the catapult? It's a bit different from the ordinary ones! It's too big."

There are many plains in Jizhou, and the trenchers in the past were not big, so I didn’t think about that aspect. Now, if you look closely, it’s really as Han Heng said. The wooden shelves outside the city are enlarged versions of the trenchers.

Yuan Xi gritted his teeth and said, "Even if it is a catapult, how many stones can they find? Shen Pei, you immediately take people to collect the cattle and horses in the city, then slaughter them, cut out the skin, soak them in water, and then connect them with needles and threads. Within three hours, you can make ten wet cowhides, three meters long and one meters wide."

Han Heng nodded and said, "No, use wet cowhide to block stones!"

Shen Pei did not dare to neglect her, so he quickly took the order and left.

Outside Xiabo City, most of the soldiers of the Yang family were also stunned by this huge catapult. Li Ru even exclaimed: "So huge, how powerful will it be?"

A young man next to him heard Li Ru's words and said proudly: "Mr. Li, it can throw stones a hundred feet away."

"What?" Li Ru said in surprise: "Baizhang?"

Zhang He frowned slightly and shook his head and said, "If it can be thrown out a hundred feet, then this power will be reduced a lot. It will have a very small effect on the city wall made of bluestone! Perhaps it can only hit the city wall, and even the wall cannot be thrown in!"

The young man replied confidently: "General Zhang, this city wall is only seven or eight feet high. The catapult I made will definitely throw the stones into the city!"

Gao Shun stepped forward and patted the young man on the shoulder, and smiled and said, "Okay, Deheng, as the saying goes, you can see it at first sight. Just let them see it with their own eyes. This is the power of the lord's weapon as the power of the country!"

It turned out that this person was Ma Jun and Ma Deheng of the Scientific Research Office. This time he went to Jizhou, Yang Fan decided to use Ma Jun's improved trench machine. After all, any invention must be tested through practice. Because it was the first time that Ma Jun was invented, as the inventor of this trench machine, Ma Jun naturally had to be present. First, he could teach the use method, and second, he could also record its shortcomings on the spot to facilitate future improvements.

After hearing this, Ma Jun smiled and said, "Sir, wait for a while. The catapult underneath will surely make your eyes lit up."

The people who operated the catapult were all temporarily drawn from the scientific research office. Next to each catapult, there were more than ten soldiers carefully selected by Gao Shun to observe and learn how others operated.

Soon, the first stone that was tested was thrown out, and the effect was not very ideal and it hit the city wall.

This scene attracted the ridicule of Yuan army soldiers. At first, they were nervous and thought that this catapult was so great. Now it seems that this is the case.

Yuan Xi and others also breathed a little relieved, thinking that if the catapult outside the city wanted to throw the stone into the city, it would only shorten the distance between the two. However, such a heavy guy was extremely laborious to push. When the Yang family pushed the catapult to the appropriate position, Yuan Xi would have the chance to dispatch cavalry and burn the catapult.

Yuan Xi smiled and said, "This thing is not useful, it's just that!"

Shen Pei suggested: "Lord, if the Yang family army wants to throw the stones into the city, they will definitely order people to push the catapults forward. However, this thing is too heavy and the action will be extremely slow. Our army can take advantage of the Yang family army's push to send cavalry to burn the catapults!"

Han Heng nodded and responded: "What Zhengnan said is right. With such a huge object, even if there are many people guarding it, our army can take advantage of it."

After hearing the suggestions of the two, Yuan Xi decisively adopted them and ordered the Wangmen to gather a thousand cavalry immediately, each of whom prepared a can of animal fat and a torch. When the Yang family army stepped forward to push the catapults, they would go out of the city and burn them.

Yuan Xi firmly believed that even with heavy troops, his thousand cavalry could break through the encirclement and burn down those hateful catapults.

However, the Yang family army's next actions made Yuan Xi and others stunned and wondered why.

The Yang family army outside the city did not push the catapult, but began to reload the stones after fiddling on the catapult. This time, it was not just about loading one piece, but about ten pieces in succession.

Yuan Xi was stunned when he saw this, pointed his hand and asked, "What are they going to do? Do you want to break the city with those stones?"

Shen Pei's face was heavy and he lowered his head to think, but Han Heng's face suddenly changed and he exclaimed: "No, the catapult outside the city must have been improved. The launch just now is just testing the range."

Yuan Xi said in confusion: "Zi Pei, what do you mean? Could it be that the catapult can really throw stones into the city from such a distance?"

Han Heng nodded and said, "If it is not bad as expected, it will definitely be possible."

Shen Pei said inexplicably: "Even if it can be thrown into the city, the catapults outside the city are only fifteen. Every time fifteen stones are thrown, our army can easily resolve them! Moreover, it is difficult to collect stones here, and the Yang family army's move is really puzzling!"

Han Heng said anxiously: "Zhengnan, those catapults have fired one stone more than once! Look, they load more than ten stones at a time!"

As soon as Han Heng finished speaking, he saw the Yang family army outside the city launching the first round of attack. Fifteen trenchers fired ten stones in a row and one hundred and fifty stones the size of a washbasin, flying towards the head of Xiabo City like chasing stars and the moon.

The stones are densely packed with the sound of the whistling wind, making people's scalp numb instantly.

Yuan Xi saw such a scene for the first time, and was stunned on the spot. Fortunately, Han Heng was quick-witted and quickly pulled Yuan Xi to his side and hid under the wall to avoid being hit by a stone.

In an instant, all the stones fell on the top of the city, and Yuan Jun immediately lost hundreds of people. Even the prepared wet cowhide was smashed to pieces.

Screams, curses, and crying suddenly rose and fell.

Before Yuan Xi could react, the second round of volley shots fell to the top of the city again. Countless Yuan soldiers had no other way except to run away with their heads. This way of siege is rare in the world. Its killing power is extremely shocking, but physical trauma is far less than the shock of the mind.

In the history of modern wars, there has always been a saying that is, "New soldiers are afraid of artillery, and veterans are afraid of horns!" The coverage of "artillery fire" is not only visually, but also auditoryly. The deafening sounds and the whistling stones made these Yuan Bing, who had just joined the army, both hearts and minds were ups and downs.

Even Shen Pei, who has always been as stable as Mount Tai, was hit by such a large scale of "artillery fire", which was so scared that his face was pale and at a loss.

The Yuan army was so unbearable that the soldiers of the Yang family outside the city were even more stunned.

Even if they were not in the scene, Zhang He and others could still experience the pain of Yuan Jun above the city.

After several rounds, hundreds of stones were thrown out. At this time, the head of Xiabo City was already full of holes and blood flowed into a river.

After Ma Jun finished the task, he patted the ashes on his hands, came to everyone, and smiled and said, "Sir, how about it? Is this effect OK?"

Zhang He was surprised. He never expected that such a powerful catapult was created by the young man in front of him. He bowed to him and said, "Mr. Ma, the catapult you created is so powerful. In the future, our army will attack the city, and will do everything wrong!"

Xu Chu smashed his mouth, reached out to wipe the corner of his mouth, and smiled at Ma Jun, "Deheng, do you also need to be equipped in the army?"

Ma Jun nodded and smiled, "Of course I need to equip the army, but I don't know who to give it to first!"

Gao Shun asked, "Deheng, how much inventory do you have?"

Ma Jun spread his hands and said, "It's all here! The lord said that he should first see the effect, and then make it on a large scale after improvement. After all, this thing consumes a huge amount, and it will take half a year to build a catapult!"

Zhang He said in confusion: "I will see that these catapults are assembled from wood, how could it take so long?"

Guo Jia smiled and said, "Ye Yi, you don't know anything about this. The most valuable thing about the catapult is the frame wood!"

Li Ru's eyes were full of energy and analyzed: "It must be the mechanism at the connection. It is difficult to create such a huge body. I guess it is necessary to have good materials."

Xun Chen nodded and smiled, "What Wenyou said is right. The most expensive thing on this thing is those machines. Not only are they small, but they must also be hard. Bingzhou does not produce much iron, so the manufacturing of trench machines has been dragged down again and again!"

Xu Chu's eyes were excited and laughed: "It seems that our army must take down this Jizhou!"

Zhang He then took a step forward and asked Gao Shun for his order: "General Gao, now the Yuan army in Xiabo City has unstable morale and unstable military morale. This is a great opportunity for our army to attack the city! The last general asks for his order and leads his troops to attack the city!"

Gao Shun nodded and smiled, "Okay! After the second batch of stones arrive in the afternoon, smash the round of Bocheng first, and your troops will go to attack the city!"

After the baptism of "cannon fire", Yuan Jun was frightened. Even Yuan Xi was so scared that he couldn't eat lunch. In the afternoon, the soldiers came to report that the Yang family army outside the city had stones delivered, and seemed to be "cannoning" down to Bocheng.

After hearing this, Yuan Xi and others were all shocked. Yuan Xi looked even more pale and asked helplessly: "I was hit by a stone in the morning. The morale of the army is unstable. Now I will be smashed again. The soldiers will collapse. What should I do? What should I do?"
