The ballista was a chariot equipped with a crossbow. The ballista stood in formation and used a flag to block the ballista. The ballista had a bed crossbow on it, and the crossbow was as big as a ballista.

The ballista could be said to be the most powerful and lethal weapon in the era of the cold weapons. "The power and range of a catapult is far less than that of a ballista. It would be better to use it to attack a city wall, but not to engage in a battle with a ballista.

There were two types of crossbows. One was the small crossbow carriage, which was easy to transport. However, they could only fire one arrow at a time, so its lethality was relatively low.

One was a bed crossbow, as the name implied, it was a large type of crossbow carriage, it was made from metal, it's weight was extremely heavy, its volume was also relatively large, it was inconvenient to transport and could fire dozens of crossbow arrows at the same time, its lethality was extremely great, it was a meat grinder from the Great Hengkong Empire's battlefield.

At the beginning, the crossbow carriage of the Great Hengkong Empire was made of wood. It was large in size, and was difficult to transport. It was easy to damage, have a short range, and had a limited lethality.

Subsequently, in order to reduce the volume, easy to transport, the metal production, not easy to be damaged and durable, the long-range lethality is enormous. However, the crossbow carriage made of metal was not small, and it was also too heavy. It required at least four horses in order to pull it and six horses in order to have speed.

A crossbow truck like this was best used to guard the city walls. Once it moved, it would be extremely inconvenient.

How to make a large crossbow truck easy to transport became the biggest problem. In this era, the bed crossbows could be considered extremely advanced, but they still needed several people to operate them before they could shoot out a full volley of crossbow bolts. Each ballista could fire three bolts, which would then be refilled.

Filling the crossbow arrows took a lot of effort, and shooting the crossbow arrows also took up manpower and resources. Every time the crossbow arrows were refilled, it would take a period of time. This period of time was the most dangerous.

Each ballista had to be secured with at least six horses in order to ensure the speed of the march and retreat. This sort of heavy weapon couldn't be left to the enemy unless it was completely destroyed. The first thing they had to do was destroy the ballista and not leave it to the enemy.

Because the inferior tribes did not have a heavy weapon like the crossbow carriage, if they were not a match for the inferior tribes, the first thing they had to do was to destroy the crossbow carriage and turn it into waste, not leaving it for the inferior races.

The ballista's crafting technique and design were similarly the most secretive things in the imperial government and would not be spread out to anyone. Helian Manqiu did not know where Gan Qianyu had gotten the ballista's drawing from.

"This design doesn't seem to be complete. It's not detailed enough."

"Yes, only the Imperial Palace has the true design, and only the few Imperial Clans know where it is hidden. This pattern was something that the military craftsmen and soldiers had researched and drawn over the years. It was not detailed enough. This was also extremely rare. A few years ago, he had met a ballista craftsman's descendant who had made a ballista for the imperial government. Thus, he was able to obtain an incomplete set of designs. We had to dismantle a ballista several times in order to get this pattern. "

"So that's how it is."

Helian Manqiu held her cheeks and thought carefully as she looked at the map. The small crossbow was not very useful and required two people to operate it. They could only fire one bolt at a time and it was not light.

Due to its weight, large crossbow carts were difficult to transport and use on the battlefield.

"Qing Yu, is there any way?"

"It's a bit difficult. Has my lord ever thought about if this ballista can be dismantled, transportation would be much more convenient?" "After being transported to the battlefield, we'll assemble them. If we don't use them, we'll dismantle them and transport them away. This way, it'll be very convenient."

Gouyu lightly tapped the table. Why didn't he think of such a simple method?

If a crossbow carriage could be dismantled, there was no need to use the six horses to pull a crossbow carriage. It could be separately loaded onto several carriages and quickly transported to the battlefield to be assembled for use. After using it, disassemble it and transport it back separately. Even if they failed during the battle, they could still transport or hide some of the parts. As for the incomplete parts, even if they were taken by the opponent, they would be useless.

After disassembling it, it would be easier to hide it and it would be more than ten times easier to move it.

"How can a ballista be dismantled as it pleases? One must know that after the ballista is damaged, the imperial government has to send people everywhere to repair it, or to equip it with a new ballista, and the old ballista will be reclaimed by the imperial government. "

"It is not difficult. The strength of the ballista should not be determined by its size nor by its weight. The crossbow carts that can be easily disassembled and transported can only fire three crossbow bolts at a time. Their lethality is also somewhat lower. "

"What is Qing Yu's opinion?"

Gan Yuxuan clenched his hands under the table. Helian Manqiu did not know that her words had made this great general extremely excited, causing his entire body to tense up.

On the surface, he appeared cold and emotionless. His deep eyes were dark as he stared at Helian Manqiu, not moving away from her for a moment.

How many other astounding talents did he have? Did he know? Would his talents allow him to become a popular talent in the Great Hengkong Empire, and eventually, everyone would be able to get their hands on such a talent?

If Helian Qingyu's talents were known by the world in the future and others found out, no one would want to kill him. Instead, they would think of all sorts of ways and means to get this youth to serve them, regardless of the cost.

Helian Manqiu looked up at Gan Yuxuan and said with a smile, "Master Qing Yu has solved this difficult problem. Master is willing to calm his anger, so shouldn't you consider Qing Yu's offense?"

"This grandpa hasn't been angered yet, how can I calm down? I didn't blame you. The military state was originally under my jurisdiction, so now that I have entered the military state, this place is my place. "

"It is because Qingyu measure is too small, a person's heart should be placed on the stomach of a lord, don't blame me, my lord."

Helian Manqiu sighed to herself. The courage and boldness of Gongye was not something that an ordinary person could compare to, nor was it something that she could compare with. At the very least, she hadn't been willing to give up her magnanimity and magnanimity to this great general. She had still underestimated him.

"Before you came, you ordered people to tell the people that they can all go and register to work, regardless of age. "In the prime of life, you can work and repair the city walls and houses, and the elderly, women, and children can cook, do laundry, clean and transport, and so on, all without worry for food or clothing."

"My lord, your kindness is so great that your chest is like the sea. I am ashamed."

Helian Manqiu cupped her fists and said, "Yes, this lowly general has forgiven you. My lord, please forgive me."

Gan Zhixuan smiled faintly, his gaze falling upon the crossbow, "Is Qingyu willing to solve this problem?"

"My lord has ordered me to do so, how could I dare to disobey him? My lord has solved the problem of the crossbow carriage, but can my lord still bear to kill me? Should I not leave my general by my lord's side?"

A devilish chuckle, a bewitching charm, and in an instant, a slight absent-mindedness. Was he really a youth?

The smiles of so many women were not even one out of ten thousand of her.

This young man was a few years older, and it was unknown how many young girls in his room had their hearts shattered. Even he was moved by such a beautiful smile, let alone others.
