Li Shao thought deeply, "But not only your Jiang family, but also the Laojun Palace, and even the entire Tang Daomen forces, can see the prospects." It is precisely because of this that the existence of Tianji Pavilion in the future is bound to open up the door of a world and create a foundation, and the predictable influence is unimaginable! Then again, without the protection of people from all sides, the cultivation world would not easily move to a secular family, which would be a taboo move. Of course, in theory, this does not mean that we are a little lax, so the Xianfeng host has taken all the risks into account! ”

Jiang Han understood that he had good intentions, and the purpose was to comfort his family, so that the Jiang family would have enough confidence to look at the possible crisis.

But he didn't know that Li Zhi's position in the minds of the Jiang family was unreasonable, especially the Jiang County Order, who had witnessed Li Zhi exerting his power in the county government, and later asked Yang Gaotang, who had a good personal relationship, and knew that Li Zhi's true strength was comparable to it.

At that time, Yang Gaoyu was already a third-level master strength, although Jiang Xianling was not a cultivator, he also understood the rarity of this strength, so those in the Jiang family had already regarded Li Zhi as a peerless master.

Moreover, this person also has Shang Fangjian, and there are several kings surnamed Li who have deep contacts, which is equivalent to the strong background of the official face, which is appalling, and the Jiang family does not believe that any force dares to provoke him.

So Jiang Han responded to Li Shao with a smile: "We don't understand the things in the cultivation world, but it doesn't prevent us from knowing one thing, that is, the text will not push our Jiang family into the fire pit, since he has made such a decision, he must have made arrangements early!" ”

Li Zhi somewhat understood that the Jiang family had something to rely on in their hearts, and his true psychology was indeed as they thought in their hearts, and being able to arrange the Tianji Pavilion here was based on the final decision after getting the old way of inheritance, and there was a second-level grandmaster, and the previous worries had long since disappeared.

Even if he encounters the worst inference and attracts a certain hidden sect force, I believe that Cheng Bi alone will be able to deal with it, not to mention that he has other means to deal with the people who come to harass.

"Uncle, after dinner, you arrange a few craftsmen for me, I have some things to build, and before Qingqi and them return, try to complete them all, so as not to delay the establishment of Tianji Pavilion."

Seeing Jiang Han's puzzled eyes, he then explained, "Actually, there is no secret, I have a method for manufacturing a crossbow in my hand, which is a newly designed large mechanical device, each crossbow machine is equipped with ten steel crossbow arrows, each of which can have a strength of two thousand catties. It shoots far farther than ordinary bows and arrows, and the lethality is extremely strong, and overcomes the weakness of physical limitations when drawing the bow and cannot be sustained. ”

Compared with Jiang Xian Ling and Jiang Han, Li Shao, who was a soldier, knew the importance of this brand-new crossbow machine, and the surprise on his face had just appeared, and he was already exclaiming: "Mr. Li really has this kind of crossbow manufacturing method?" Can it make it difficult for even a first-level master to escape? ”

Li Zhi nodded, "This kind of crossbow, not only is each arrow made of steel to make the crossbow body, but the tension spring chain that guides the crossbow string to pull is also made of steel, and the elastic force of each tension spring is different. Arrowboxes can actually contain more bolts, but those are designed to kill enemies on the battlefield. The crossbow used to deal with cultivators will reduce the elastic dispersion of the chain as much as possible, so as to exert a faster meteor-like effect. ”

That Risong's excited expression was no less than Li Shao's, "In the Spring and Autumn Period, there have been relatively dexterous mechanical device crossbows, but they are all wooden arrows, even iron arrows are very rare, but the performance is a good crossbow, even if the longest range can reach a mile, through the machine to make a cluster of shots or bursts, I am afraid that it is not as good as the single arrow in Mr. Li's mouth." If this kind of crossbow really had such a huge tension, it would really not be difficult to shoot a cultivator! ”

Li Zhi smiled slightly and said: "My crossbow arrow does not even have a tail, but adds a rotating air guide groove to the arrow, which can make the crossbow arrow rotate after it is fired." That kind of rapid rotation force, as long as a first-level master strength dares to catch it with his hand, he will be slashed off by the upward rotation force of the arrow in the blink of an eye. What's more, the momentum of the rapid whirl can increase the speed of the arrow several times, and when it is within reach of the naked eye, the body shape has been accurately locked, and without the blessing of the special body method, it is impossible for ordinary master-level cultivators to avoid its rapid flying momentum! ”

"May I ask what is the core of these crossbows? Mr. Li, please forgive me for being reckless, I was too curious. ”

That day Song's question was indeed a bit abrupt, just like the refining method of the Qiankun bag, or the secret formula of gunpowder, all of which belong to the category of unique secret arts, without permission, under normal circumstances, such a taboo opening of the mouth is really offensive.

But Li Zhi originally had the intention of handing it over to Na Risong, so he didn't care about saying the ingenuity in it: "Actually, it's very simple, but in all mechanical devices, the mechanism can be called the most important part, it is small and secret, but it affects the whole body and controls the overall movement trend!" The crossbow I designed is heavy on the tension spring chain that plays the role of pulling strings, but ordinary steel is difficult to withstand the huge tension pulling, and it still needs to be forged by Brother Na Song overnight. Because in the process of pulling the crossbow string, the tension force of the tension spring chain is not linear, but the force of the composite crossbow arm is used, so that the force used to pull the string will meet the extreme conditions! Take ten arrows as an example, each with a range of at least several miles, the longer the range, the greater the tension required, and once achieved, it is not an exaggeration to reach the arrow at a distance of one mile! ”

Na Risong himself is a very experienced foundry craftsman, and he can understand the deep meaning of Li Zhi's words better than others, at this time, I saw that his facial expression had already been distorted by shock, and he gasped with a hiss, and then he spoke in a tremolo:

"Oh my God, replaced by a steel crossbow arm, how can it have such a sensational tension? If it is built into an ironclad car that can hold hundreds of arrows, after the corresponding elastic spring chain is increased, wouldn't it be a mud chop on the battlefield? ”

"Hehe, what Brother Song said that day is good, this kind of crossbow is extremely versatile, and it is indeed my plan to load it in an ironclad car! But where is the amount of high-quality steel, at least for now? An arrow is five feet long and half an inch thick, and a hundred arrows plus the steel weight of a crossbow and an ironclad car, a car has tens of thousands of catties. At the moment I am still looking for a way to carry the load, but I believe that there will be a perfect solution in the future! ”

"Hehehe, I'm a little taken for granted, but ten crossbows are already amazing, and if there are arrows smeared with poison, I'm afraid it's the power of the grandmaster, and I don't dare to enter the range of such arrows!"

"Poison can't be touched at will, it's too vicious! This time, I will personally teach you how to make such a crossbow, and when the Tang Dao order for the Cliff Mountain Arsenal is completed, you will need the eldest brother to be in charge of this matter! Before that, you can design a small single and double arrow crossbow that is more suitable for carrying around according to the principle of the finished product. And because Zhang Xian is modulated in advance, it is more mobile and flexible, and at the same time, it also eliminates the limitation of the huge tension crossbow launch! ”

"But if it is made of pure steel, no matter how light it is, it is not suitable for long distances, can some of the structures be replaced by wood?"

"In principle, it is possible, but it will lead to a significant reduction in force and range, so I suggest that the number of tension spring chains be considered in the streamlined parts, but the special steel is not considered to be replaceable. Of course, trap crossbows could have been found in a different way in their miniature design, such as being strapped to an arm. Moreover, the arrow is added to the wooden tail, which is also the advantage of a single-shot crossbow, and the weight of the arrow is reduced several times. ”

"The ten pieces that Mr. Li said, but there is only one arrow slot?" Knowing the general construction principle of the crossbow, Narimatsu raised questions again.

"That's natural, multiple slots only reduce the speed of the arrows, and each time you add a slot, the weight and design difficulty increases several times! At that time, the single arrow slot had a double track, and two could be fired at a time. The Arrow Containment Device is a cylinder that rotates itself to allow the arrows to fire automatically. A rotary fan is installed at one end, so that a relatively strong airflow can be formed in the cylinder, and the air duct above the crossbow rod is close to the tail, and the instantaneous infusion of airflow is the core principle of trajectory and force stimulation and control. Li Zhi replied.

I didn't see the real thing, even if he explained it thoroughly, others didn't understand it, and even Narimatsu couldn't understand the subtlety.

So the desire for the unknown made Na Risong unable to bear the urgency in his heart at this time, and looked at Li Zhi, the meaning of which could not be more obvious.

On the side, Jiang County's order understood it, and he said happily: "Text, not only are they eager to see the real thing, but I am also a little impatient!" You can use the wine at any time, hurry up and eat some food, and the deer hunting meeting will end in two days, so you should hurry up and start preparing! ”

That day, Song frequently responded with his jaw: "Then I will organize people to forge steel by hand, and it just so happens that the foundry craftsmen of Cliff Mountain are also there!" ”

Li Zhi waved his hand, "Don't be in a hurry, there are still many counterintuitive designs in the crossbow, all of which need to be built in advance with various special tools, and you and the Jiang family craftsmen need to do a good job of division of labor in advance, and each has its own responsibilities, so as to make more effective and reasonable use of labor!" ”

"Oh? Mr. Li said, what other unusual designs are there? Narimatsu's curiosity was even greater.

"For example, the arrow shaft and guide rail are curved and have a certain curvature, because the arrow shaft is made of steel and does not have flexibility, and the flexibility will greatly affect its own elastic vibration changes when flying in the air, which can reduce the resistance caused by air vortices. Therefore, the arrow with a radius is flying forward along a wave-shaped trajectory, and its vibration frequency amplitude directly affects its flight speed and accuracy! In addition, bending the arrow shaft can avoid friction with the guide rail, and the crossbow machine potential can be completely converted into the kinetic energy of the arrow, so it is essential to replace the elasticity by the curvature, so it is necessary to build the accuracy of the bending arc, and forge the shape, size, and weight of the same ruler in advance to ensure that the efficiency of batch production is higher, and it is also a standard for the standardization of similar crossbow arrows in the future. ”

"What else?"

"Then the arrow part needs to be wound with a fixed size string, and the rope is spiral-shaped, which can cause the arrow to rotate around its axis due to aerodynamic forces in flight, so as to improve flight stability, precise range and accuracy. This kind of rope requires extremely thin steel wire to add weight, so as to avoid the rope fluctuating in high-speed flight, so its manufacturing also needs to formulate steel wire adding standards in advance, as well as related rope making masters. ”

"Rope rubbing master is not a problem, there are people in the Jiang family who are good at this kind of work!" Jiang Han added.
