Often the more simple the mind, the more touching people can be, Wei Yao and Wang Zebang only knew that there was a team of people with their wife, but they never seriously understood what kind of people followed her.

Sure enough, those who can follow Mrs. are naturally people with a generous temperament and a heart of gold like her.

Yu Wensheng bowed his head, indicating that he understood the meaning of Zheng Quqi's words, and he said: "Since you are some trustworthy people, you might as well talk about the special features of this ballista?" ”

In fact, the craftsmen didn't know very well, after all, these weapons were jointly developed by Zheng Gong and the Ordnance Superintendent, and they only assisted in the assembly of later instruments, and did not participate in the construction.

The two craftsmen looked at each other, and they didn't know how to speak for a while, so they could only look at Zheng Quqi.

Zheng Quqi didn't hide it like a secret, she knew that they were all curious about the difference between this "ballista" and the "multi-bow bed crossbow".

"The ballista does not use ordinary spears or arrows, but stone shells and cannonballs, so its firing device is different, and the frequency of its firing, that is, the time difference between firing a cannonball and the reloading magazine, is small, and it is ten to dozens of times faster than the reset of all other heavy equipment."

She made an action, pretending to hold a stone projectile in her hand, then "throwing" it from the ballista's loader, activating the torsion spring, and then signaling the crossbow arm to drive the bowstring to throw the projectile, and the whole process was demonstrated in the form of the ballista.

"It can achieve rapid reloading and launching, continuous, marching locust-like culling."

Sound...... It's amazing.

Those who don't understand it only capture key words and sentences to understand, and they don't seem to understand, and those who understand are stunned and surprised.

"Zheng Gong, what is the principle of the power of the ballista? According to its range and rapid launch, it must require strong force to promote, and the technology currently mastered by various countries is not yet up to rapid preparation for war, and this process will inevitably require a lot of manpower to twist the winch, how is this done? ”

"That's right, the three-bow bed crossbow built by the Giant Deer Country caused a sensation in the Seven Kingdoms, the bed crossbow they designed replaced the giant bow and crossbow, and the individual bow and crossbow were already difficult for ordinary crossbows to break the fine shields and armor, but the three-bow bed crossbow can cause more terrible lethality, can our artillery crossbows go to the next level?"

The craftsmen of the other warehouses rushed to hear the news, and the servants were curious to surround them, in the past, they did not have much opportunity to get the guidance of Zheng Gong nearby, but now the opportunity is rare, and they can't help but want to come over to get a "scripture".

"How is the propulsion of a cannonball and a stone projectile compared to a spear? Why did Zheng Guild abandon the unbreakable spear and choose a blunt object to shoot? ”

Zheng Quqi didn't expect that she just brought Yu Wensheng to participate in her recent research results, but it suddenly turned into a large-scale lecture venue.

But since they are thirsty for knowledge, she does not hesitate to explain them one by one.

"What else do you want to know?"

She looked around at everyone in the storeroom, smiling gently and patiently.

"We all want to know, what is the difference between the ballista built by Zheng Gong and the three-bow ballista bed built by Julu Kingdom? Which is the best to lose? ”

Other laymen don't understand, but Wang Zebang and Wei Yao also have such a question in their hearts at this time.

Zheng Quqi saw that the voices gradually subsided, and everyone no longer asked questions enthusiastically, but began to calm down and wait for her reply, and then she spoke.

"To put it simply, the firing force generated by the deformation of the traditional crossbow arm cannot drive the speed and distance of the spear at all, so the bed crossbow is produced, but the bed crossbow is not yet able to achieve the arbitrary control, it not only needs a cumbersome winch to charge before launching, but also cannot give the bed crossbow a flexible sense of direction and elevation angle......"

"And so, there were ballistas."

At this time, Zheng Quqi mentioned a few points, first, the bed crossbow has a long charging time, and second, it is not flexible enough, and the control and adjustment of the direction cannot be achieved.

"So, Zheng Gong's ballista improves these shortcomings?" Someone asked.

Zheng Quqi nodded, and she pointed at the ballista: "That's right, I installed a torsion spring group at the front end of the main beam, this spring technology is now mature, and it will soon be promoted to various crafts in the Ye Kingdom, it is the power device that drives the projectile." ”

"Look, do you have a dovetail groove on the side of the beam? This is a long guide rail, the slider in the long groove can slide back and forth, the rear is equipped with a set of exquisite excitation mechanism, which can easily lock and release the bowstring, as long as the handle is pulled, the slider can be dragged by the rope to move, when the firing mechanism locks the bowstring and pulls it back, the weapon is in a state of readiness, and the circular spike wheel can easily adjust the force of the projectile, and perfectly lock the range distance. ”

She bent down, and all eyes followed her every move.

"There is also a free-turning pedestal that allows you to adjust the launch orientation as you like."

"In addition, one of the things you are most concerned about is whether the improvement of the ballista can surpass the bed crossbow of the Giant Deer Country, I think the two cannot be compared at all."

"As for why the stone projectiles and cannonballs are installed......

"This explanation is far less clear than what you have seen with your own eyes, you will know tomorrow's drill, the remaining issues will be put on hold for the time being, everyone hurry up and finish the matter at hand, and then discuss it slowly when we return from the war."

She probably just talked about it, not that she was hiding her secrets, but that the current war was imminent, so she naturally did the right thing first.

Everyone listened with relish, although the abrupt end made them unsatisfied, but it was also temporarily relieved of their "gluttony".

"Yes, everything is arranged by Zheng Gong."

This time, Zheng Quchi spoke in public, in addition to taking advantage of the situation, she didn't want them to speculate wildly, because she was worried about the upcoming war in her heart, and missed the big thing.

Anyway, everything will be made public to the world in the near future, so it is better to give them a reassuring pill in advance, and at the same time a reassuring pill for the whole army.

- Ye Guo is no longer the "broken down" it once was, it is trying to rise, it just needs time, and in the future it will definitely not be worse than any country, she wants to convey such a confidence to them.

Speaking of which, Yu Wensheng and her also have a tacit understanding, he took the initiative to open this mouth and asked her to "reveal the secret" to everyone.

Now I am afraid that their Ye army's matter of "ballistas" will soon set off a craze in the army.

After leaving the fire storehouse, Zheng Quqi took them to visit other gold, wood, water, and earth storehouses, including her specially improved machete, which was hard and heavy, and could cut off the horse's legs with a soft knife, as well as her self-created repeater, which fired ten arrows in a row, and she improved the types of common weapons.

In the gold storehouse, she also spent a lot of money to make a batch of scale armor, which is not only the highest defense of Ye Guo's current defense, but also can withstand the penetration of the current individual shooting intensity to the greatest extent, which she has experimentally verified, but the number is limited, and how to configure it reasonably still needs to be decided by the general.
