After a while, Zhao Feng, Xu Shu, and Xiong Da walked out of the camp and came to the temporary resting place of the Mo family students.

A group of students, seeing Zhao Feng and Xu Shu coming, stood up one after another, gave Zhao Feng a long look, and said in unison: "Meet the dean!" ”

Then he waved at Xu Shu again: "I've seen the fake dean!" ”

Zhao Feng was very satisfied with the title of these students.

These students, who do not have official positions now, immediately call Zhao Feng a general, they can also call Zhao Feng a state pastor, and even call Zhao Feng the king of Zhao!

However, among so many titles, Zhao Feng cares most about the identity of the dean.

After all, Zhao Feng is also the dean of all academies, and he can be regarded as an indirect protégé all over the world.

Zhao Feng nodded in response, and then smiled: "Who will help me introduce the specific effects of these catapults?" ”

As soon as the words fell, Xu Shu directly called and said, "Shao Kang, you come to help the general explain." ”

Shao Kang waved at Xu Shu: "Oh! ”

Then he gave Zhao Feng a long look, and then pointed to the large catapult: "This catapult, after our use, has drawn several conclusions. ”

"First, the maximum range of this catapult should be about 300 steps, depending on the size of the stone."

"In addition, using the maximum range projection will cause damage to the catapult itself, and will reduce the number of uses."

"According to the first scrapped catapult, it was about ten times with the maximum range projection, and many important devices needed to be replaced."

"Second, the best range of this catapult should be about two hundred paces."

"This range will cause normal damage to the catapult, and it can throw about fifty stones."

After Zhao Feng heard this, he frowned slightly.

Although the range is indeed long, it has reached a distance of one mile.

At this distance, if it is used to sneak up on the enemy's camp, it will be very effective.

It's just that this service life is too short!

The maximum range is used ten times, and the regular use is fifty times, and important components need to be replaced.

That alone doesn't make it possible to use it on a large scale.

After all, important parts must be similar to gears and need to be polished manually.

These objects are not only handicraft-demanding, but also time-consuming.

Most of the construction of the entire catapult was spent on these important components.

As for the other large components, those can be increased by manpower.

However, considering that this is the first generation of large-scale catapults, these key parts will definitely be improved in the future, so Zhao Feng can also accept it.

After all, this is the pinnacle product of the Southern Song Dynasty!

Originally, Zhao Feng also wanted to let the large catapult try it out to see the realistic effect.

Now this thing can only be voted fifty times, and once it is used, it is one less time, so Zhao Feng dispelled this idea.

After all, at a critical time, maybe just because of this more time, you can crush the morale of the other party.

Even if it is not a critical time, when it is sent to Xinzheng to defend the city later, one more throw will be able to kill many more people.

Anyway, since it can be sent here, it must have been adjusted and can be used normally.

In addition, in the process of tuning, it may have consumed several opportunities to use it.

Zhao Feng then nodded: "Go on!" ”

Shao Kang waved at Zhao Feng: "Oh! ”

Medium-sized and small catapults were then introduced.

According to the introduction, the maximum projection distance of the medium-sized catapult, which is about one hundred and twenty steps, has also achieved Zhao Feng's expected effect.

The disadvantage is that there is also a so-called number of uses, and key parts need to be replaced after damage.

Fortunately, under normal circumstances, it can be used two or three hundred times, and the specific number of uses depends on the usual use method.

The maximum projection distance of small catapults is only about seventy to eighty paces, which is only a small half a distance away from archers.

The advantage is that the accompanying twenty people push hard together, and they can move in a small area on the battlefield.

After that, Shao Kang introduced the miniature catapult, that is, the catapult developed by Huang Yueying herself.

The maximum throw distance of this miniature catapult was only between fifty and sixty paces, which was slightly farther than that of the archers.

Of course, the stones thrown out are much smaller than those of the previous catapults.

In the current unit of measurement, the stone of the miniature catapult is about two pounds or sixty catties.

According to Zhao Feng's early conversion, the weight corresponding to later generations should be about thirty catties.

And Zhao Feng also found the structure of this miniature catapult very interesting.

The structure of this miniature catapult is actually a small catapult that has been reduced by about half at the top, and the bottom part is made up of four bicycles that are slightly larger.

Naturally, the wheels have also been changed, and they are much wider than the wheels of ordinary carriages.

The advantage of this miniature catapult is that it can be moved by four people pedaling a bicycle.

It's a flexible version of a catapult!

Of course, after all, it is a miniature catapult, and the stone thrown is not big, whether it is useful or not, how useful it is, Zhao Feng can't judge it for the time being.

It's just that Zhao Feng always thinks that this miniature catapult looks weird.

It's just a moment and a half, and I can't tell what's strange.

Zhao Feng pondered for a while and looked at Shao Kang: "Operate the miniature catapult, let me see the specific effect!" ”

Shao Kang waved at Zhao Feng: "Oh! ”

After saying that, he beckoned the four of them and quickly ran to the miniature catapult, and the four of them walked to the bicycle, and one of them pushed hard behind him.

After that, the five of them demonstrated.

If you ride with four people alone, the speed is very slow, slightly slower than normal human walking.

But those who are pushing in the back can free up their hands and carry out the stone-throwing operation.

It's just that all the operation processes are completed by only one person, and the projection speed is not fast.

If the movement is effective, the four people riding can directly take the handlebars to increase the speed of the catapult.

If one person pushes in the back and four people ride, the speed of the miniature catapult is about the same as that of ordinary people.

Seeing Shao Kang demonstrate the two sides, Zhao Feng had a flash of inspiration in his mind, if he used a wooden plank, he would surround the four bicycles that were several sizes larger.

So this thing should be a tank? Armored vehicles? The prototype of a class?

Of course, it is similar in shape, and the actual use is very different, and even what the actual use is, it is not clear now.

Therefore, it is completely unnecessary, because I want to make it like a tank or an armored car, and deliberately add a few wooden boards.

After all, it can be seen from the speed of exercise that the weight of this thing is already very reluctant.

Maybe with a few planks, just four people won't be able to step on it!
