Throne of Vientiane Civilization

According to Zhuang Mengdie's idea, they don't need a fixed platform at all. The city defense crossbow they create only requires two to three soldiers to operate it. Wherever you want to attack, you carry the city defense crossbow to that wall. Just get on one.

Not only does it solve the problem of flexibility, it can even reduce some of the wall space that would otherwise be occupied by city defense crossbows.

After that, regardless of the soldiers on patrol on the wall, the two of them spread out the animal skin drawings and started drawing with charcoal.

Although this idea was proposed by Zhuang Mengdie at the beginning, as a time traveler, Zhou Xu was able to come up with many useful ideas after having such an idea. In just a few words, he could enrich Zhuang Mengdie's ideas. This idea made Zhuang Mengdie regard him as a god.

However, Zhou Xu couldn't help feeling a little ashamed when he felt Zhuang Mengdie's gaze.

His advantage is that he is a modern person who has withstood the impact of huge network information. Compared with him, he can think outside the box and create something from scratch with his own mind. Zhuang Mengdie, who came up with this idea, is obviously more genius.

After going back and forth, the two of them decided on the latest design of the city defense crossbow directly on the wall of Huangsha City.

If you want to make changes later, you can only wait for the actual product to be made, see if there are any problems during the specific use process, and then make targeted adjustments and improvements.

"Then let's make the first version of the city defense crossbow and test it first."

They basically brought the tools and materials they needed themselves, and there were also many materials and equipment in Huangsha City for them to use at will.

The work started quickly. Although the specific positioning of the city defense crossbow and the three-bow bed crossbow has completely changed, but leaving this issue aside, many parts of the city defense crossbow are actually smaller versions of the three-bow bed crossbow. These parts, Zhuang A few assistants brought over by Mengdie can easily handle it.

Zhuang Mengdie himself concentrated on producing the core components.

Putting aside the previous bearing design that has become obsolete, in order to improve stability and durability, the core structure of the bed crossbow is also made of metal, and this city defense crossbow is naturally no exception.

As for this core component, only Zhuang Mengdie can do it for the entire Zhou Dynasty.

"Deputy Minister, the parts are all cast."

"Okay, thank you for your hard work."

As he spoke, Zhuang Mengdie glanced at the plates where the parts were placed one by one, picked up one of them with iron tongs, and put it directly into the hot forging furnace.

After the metal part was burned red, he pinched it out, then waved the small hammer in his hand, which was no bigger than a palm, and started to beat it.

At this time, Zhuang Mengdie was in a state of complete concentration, completely ignoring the existence of other people around him.

One of the accompanying members was stunned as he watched Zhuang Mengdie knocking on the parts.

"Brother Li, what the deputy minister is making now should be the core component, right? Just made it directly in front of us? Don't you need to avoid it or something?"

"unnecessary."

The man called Brother Li glanced over there.

"The structure of the core components is not a secret. The real difficulty lies in the production craftsmanship and control of precision."

While speaking, Brother Li threw a piece of wood in his hand to the member.

"Speak, keep talking, and don't stop doing the work at hand."

"oh oh."

The accompanying member quickly got busy while responding.

After Brother Li saw it, he continued talking.

"Parts cast simply with molds are very brittle and not strong enough, so they can easily break. In order to increase the strength, they must be repeatedly forged. You should know this, right?"

The accompanying members nodded quickly.

"Know."

Entering the Ordnance and Equipment Department is a common sense question, and Brother Li continued...

"When the mold is cast, the size of the parts can be unified, but during the forging process, as the strength of the parts increases, the thickness, width and other dimensional data of each part will also change accordingly. Variety."

When Brother Li said this, the accompanying member vaguely knew what the problem was.

"So taking this into consideration, our molds are generally made appropriately larger to reserve a certain size for subsequent forging."

"Under this premise, there are a total of twenty-seven parts that are combined into a core component. If one of these parts is not forged in place and cannot fit tightly, it will affect the stability and durability of the entire finished product. and the normal operation of internal agency structures.”

Having said this, Brother Li paused, and then looked at the accompanying member with a half-smile, whose expression was gradually beginning to be confused.

"That is to say, when you are forging it purely by hand, you must ensure that the sizes of the twenty-seven parts are completely matched and that they can be put together perfectly."

"So far, the only one who can improve the accuracy of this craft to this level is the Deputy Minister. If you can do it, the Deputy Minister will definitely be very happy. After all, someone will be able to help her. The work is divided.”

After listening to what Brother Li said, facing that kind of precision requirement, the accompanying member felt that it was simply abnormal.

But then, another trick came up.

"Brother Li, what do you think about the method of directly filling the seams with water when it is impossible to achieve a tight seal?"

What this accompanying member means is to pour molten copper or iron juice into the gaps to fill them. In this way, the entire structure can be tightly fitted.

When Brother Li heard this, he rolled his eyes subconsciously and felt speechless in his heart.

But when he thought about it, he realized that this accompanying member was just here to help them, and was not a formal technician, so he felt relieved again.

After all, the other person is just a handyman, so it's normal to not understand this.

"This core component is not just as simple as putting twenty-seven parts together. As I said just now, there is a mechanism and internal linkage in it. Once the juice is poured, it is possible to make an entire core component Abandoned."

"At the same time, such a delicate mechanism needs to be disassembled at regular intervals and maintained on every internal part to ensure that it can be sensitive and smooth enough when used. How do you usually take care of it?"

Brother Li's words completely gave up on the entourage.

When he came to the Ordnance and Equipment Department, he certainly didn't just want to be a handyman, but if he wanted to get ahead, he was obviously still far away.

Putting aside this small episode, a period of time passed and an ingenious mechanism component was quickly assembled in Zhuang Mengdie's hands.

Every piece fits tightly and perfectly, and the super precision brought by those skillful hands is simply amazing.

The manufacturing of core components can be said to be the most time-consuming, and other components have already been prepared and waiting.

The final assembly work was completed quickly, and their first city defense crossbow was officially launched at this moment!
