With Lin Meng's return, the drawings of Yang Zizong and Wang Zongwei were drawn one after another.
When the drawing was handed over to Qingcang, he looked at it for a while, his face expressionless, as if he was thinking about the problem.
He placed the blueprint of the city rush vehicle in front of the sand table.
"Everyone, come here and let's brainstorm ideas.
Take a look at this drawing and see if there is anything that needs improvement."
At the same time, he pointed to the city on the sand table.
The rows of wooden blocks in front represented the city ramming vehicles.
"We need to improve it based on the actual situation.
How can the city rush vehicle rush to the city gate safely without losing as much personnel as possible?
This is very important because we don't have many troops.
We can only use these equipment to replace We're done."
If this is the case, the difficulty is not small.
Lin Meng looked left and right, expressing confusion, "Looking at this is not as fun as killing people.
Commander, I can't see the difference.
I won't participate."
Qing Cang had no idea why Lin Meng was behaving like this, but Zhang Liao shouted: "I think you guys are too busy, why don't you go bring some tea and water for the men to drink?"
Lin Meng was not angry but said: "Brother Zhang has spoken, then I will do it."
Give him something to do, and he won't talk nonsense.
He went downstairs, prepared tea and left.
After the eight people at the scene watched for a while, Qingcang first asked Yang Zizong: "Do you think the structure of your car is strong?"
Yang Zizong said with some pride: "My entire vehicle uses a mortise and tenon structure, which can withstand violent impacts.
It can be dropped from a height of ten meters by a hundred kilograms of stone without cracking."
The mortise and tenon structure is a commonly used structure in ancient Chinese wooden buildings.
This structure basically does not require a single iron nail.
It uses special processing of the wood to interlock and is extremely strong.
This city bus is painted three meters high, about the same size as a small bus.
It relies entirely on people to push it, and the same is true when attacking the city gate.
He then asked other people, because Yang Zizong must be confident in his stuff, and these city assault vehicles have also been tested in many battles, large and small, and their quality is definitely guaranteed.
"Do you think the structure needs to be changed?"
Probably because the three armed battalion commanders had seen too many such car rushes and were very indifferent.
They looked at it for a long time and still couldn't find anything that could be changed, so they didn't say anything.
Instead, Wu Chaojing raised a question.
"I think the most fearful thing about open fire is that the car is made of wood.
Once it encounters fire, it will be a disaster."
Zou Wei nodded in agreement.
He had witnessed several major sieges.
"Yes, once this city ramming vehicle hits the fire, it will almost be scrapped.
Let alone siege the city, it will be burned to ashes before it reaches the city."
Wood has this shortcoming, but there seems to be no other more suitable material besides it.
Xu Xun said: "But if you don't use wood, just use other materials.
It is definitely not as light as wood, and it is quite troublesome to process.
It is so heavy.
If you want to push it, the number of people needed will naturally increase.
All the troops are here.
They are equivalent to being exposed to the enemy's attack range, and the casualties may increase. " Speaking of which, no one really cares whether the design is reasonable or not.

Everyone keeps using it, and that’s it.
Probably because it is simple and easy to make.
At this moment, Qingcang thought of the car.
Although it was made of iron, it was just covered with iron, which could still protect it from wind and rain.
"Let's do this, let's add a layer of iron to this city car.
Xu Dezhi" "exist" "Can you find an iron sheet with a uniform thickness?"
"Return to Commander, this is no problem."
"Well, can it be made as thick as this?"
He took out a piece of wood that was about two millimeters in size.
Because the measurement units in ancient times were very different from those in modern times, he didn't know how to describe these two millimeters, so he took something over to compare.
"Anything thinner than this is fine."
"Okay, let me tell you my opinion.
What you just said was very good.
But I have my own ideas.
If there is something wrong, you can put it forward."
Qingcang took a pen and drew an eaves section on the new drawing, and then extended it to form a roof.
"This is a roof, wrapped with a thin iron sheet, which can protect the safety of the pusher.
It can also prevent fire and is not too heavy to cause a burden."
Wu Chaojing patted his thigh and said: "I never thought that it could be wrapped with iron sheets.
If that's the case, the city ramming vehicle can ignore the fire attack.
By the way, the wheels also need to be added with iron sheets to rush the city pillars.
It also needs to be wrapped.”
"Consultant Wu is right.
The wheels should also be wrapped in iron sheets.
In order to prevent the enemy from rushing over and destroying them, I have another suggestion.
Some weapons should be installed around the city ramming vehicle.
As the vehicle moves forward, once it encounters The enemy also keeps them at bay.”
Zou Wei also joined in and said: "In this way, wherever you go, you will be invincible."
Yes, such a city-attack vehicle is like a harvester, harvesting everything it goes.
When people thought it was over, Qing Cang continued: "Also, Battalion Commander Wang is responsible for this.
I don't want to use manpower.
I am going to use horse power.
Put the horses in the city ramming vehicle and rely on them to drive."
Zhang Liao, who had been silent just now, also echoed: "What a good idea.
This will free up the remaining warriors, which is equivalent to using horses to replace warriors to complete the task of storming the city."
Wu Chaojing gave a thumbs up and said: "Yes, that's it.
Why didn't I expect that the commander is the real staff officer?
He is really high."
Qingcang's position is different.
He wants to grasp the overall situation.
With modern thinking, he can naturally think of a wider range of things.
If nothing else happens, this plan will be finalized.
Just when everyone was agreeing with Qingcang's words, there was a voice that was not very gregarious and said: "I don't think it is appropriate to use horses."
Qingcang was feeling energetic.
"Oh Xu Xun, you have a better way."

Vaguely, this person named Xu Xun seems to be more suitable as a staff officer than Wu Chaojing, but Qingcang will not let him replace Wu Chaojing.
At most, he will be of the same level, and all conflicts must be foreseen in advance.
And when the team is strengthened, these literati will be assigned to their respective legions.
Xu Xun explained: "The so-called horse power is known from a distance.
This sentence has another meaning, that is, the endurance of horses is strong, and the explosive power is correspondingly lower.
What if we use cows?
I have seen cows explode wildly.
One ox can overturn three horses.
Moreover, using horses is too wasteful.
The contribution of this horse on the battlefield is much greater than that of the ox.
In addition to being killed for meat, it is also used for plowing the fields. " Xu Xun always quotes some allusions and poems when he speaks, which makes people feel that he is a talented person.
"What Xu Xun said makes sense.
Battalion Commander Wang, take note.
We have decided to have Yang Zizong and Xu Dezhi cooperate with you to complete the first sample function.
As for how to do the best, it is your responsibility."
"Yes, Commander" The improvement of the first city-attack vehicle has come to an end, and the rest will be left to Wang Zongwei and others.
He only provides one direction.
As for the experiment, that is their business.
