Wei Long's attitude didn't seem to be very good, he glanced at Zhao Qing from time to time, and then looked at Yang Duwei, his eyes were full of inquiry, obviously very dissatisfied with Zhao Qing's appearance here. Pen & Fun & Pavilion www.biquge.info

As if he was completely unaware of Wei Long's dissatisfaction, Yang Duwei said with a smile: "Lord Wei, Captain Zhao is looking for your ordnance supervisor to communicate, I see that your ordnance supervisor is really busy during this time, and Lord Wei can't get out, but the military is no matter how big or small, I am afraid of delay, so I directly brought Captain Zhao here." He deliberately mentioned that Zhao Qing's current identity is the captain of the forbidden army, and he was forced to make this decision because of military affairs, and he also blocked Wei Long's interrogation in advance.

Hmph, if a school captain wants to see me, he has to see me, isn't it in the name of a Guigumen person? Wei Long muttered in his heart but didn't say it, this time Jiangmen's intention to reach into the weapons prison was too obvious, but he used an upright and righteous conspiracy, so he couldn't say anything, after all, Zhao Qing had indeed entered the scope of his investigation, and this kind of talent who had an advanced understanding of firearms Da Zhou could not miss it. But the inspection period has just begun, the details of this mysterious young man who suddenly appeared are not yet clear, and the report sent to the cardinal mansion has just been on the road, let Wei Long call the shots and let Zhao Qing join the weapons prison now, he will never dare, once something goes wrong and the military secrets are leaked, it is not a simple matter of losing his head, it is to connect the nine clans.

But now Zhao Qing is looking for the door, coming to this secret place that must not be exposed, not mentioning the matter of joining the Weapons Prison, just to communicate, Wei Long is embarrassed but it is not easy to drive people away, after all, if there is no accident, Zhao Qing will definitely join the Weapons Prison, and his status is likely to be much higher than him, if he does something disgusting now, so that he is resistant to the Weapons Supervisor and is unwilling to serve the Weapons Supervisor anymore, then he will be a sinner of the Great Zhou.

Wei Long's face was uncertain for a while, and he hesitated in embarrassment, Yang Duwei had a smile on his face, and Zhao looked at it in his eyes, and after thinking about it, he also figured out the clues. Of course, he is not interested in the busy stuff of these guys underground, this time he is just looking for craftsmen who are proficient in iron craftsmanship in the Arsenal Prison, this kind of person must be indispensable in the Armament Prison, Zhao Qing provided ideas, they made real objects, and it was not difficult to engrave rifling into the barrel of the roaring young general, and after thinking about the wording for a while, he arched his hand and smiled: "Brother Weilong, the idea of bringing thunderbolts to the bed crossbow bolt that the junior brother said before is still useful?" ”

Wei Long didn't expect Zhao Qing's first sentence to ask this, the effect of the thunderbolt on the bed crossbow is surprisingly good, with both the power of artillery and the penetration accuracy of the bed crossbow, several bed crossbows in the inner city have been moved to the outer city to replace a few artillery, but the number is too small It is a pity, but it has also greatly enhanced the defense force of Ningjiang Prefecture City. Thinking that the ordnance supervisor took advantage of a lot of people in this Guigumen but was still so guarded against others, and people were not interested in their sense of confidentiality, but they didn't necessarily guard against him like a thief, Wei Long couldn't help but feel a little guilty, and clenched his fists and said: "It's easy to use, Zhao Gongzi has helped me a lot of weapons supervisors, and if something happens here, it will definitely be reported to the cardinal government to make a name for Zhao Gongzi." He was still tactfully hinting that Zhao Qingdon't be in a hurry and make it difficult for him.

After Zhao Qing joined the army, he faded the mind of joining the weapons superintendent, although he was not in his position and did not seek his own politics, and the research of military science and technology was also strictly limited to the ordnance superintendent, but he is now more interested in the formation of the first musket team, if it were not for this roaring young general It is really difficult to go to the battlefield, he will not deliberately come here. He took out the roaring young general he carried with him and said to Wei Long: "Today, the little brother has nothing else, I just want to transform this roaring young general, my soldiers are really not comfortable with this roaring young general, it just so happens that the little brother I have some improvement ideas, but there are too few craftsmen around, so I want to ask a few veterans in the armory prison to help, which is also conducive to the military, and ask Brother Weilong to help." ”

Wei Long looked at the roaring young general, and his eyelids jumped. It is not an exaggeration to say that the design of this roaring young general is the highest secret of the Liaodong Military Weapons Supervisor, in order to develop this thing, I don't know how much manpower and material resources have been invested, and it was reluctantly made a finished product, but it was criticized by Zhao Qing a few days ago for nothing, and the arrogant Wei Long was hit very hard. Now goodbye Zhao Qing, he actually proposed that his subordinates wanted to improve and improve with a roaring young general, Rao is knowledge knew that the other party's firearms knowledge level was far beyond his own, and Wei Long still felt hot on his face. You must know that the precision equipment of the roaring junior is integrated, and it is easy to make changes, and the ordnance supervisor thinks that if you want to overcome the many defects of the roaring junior general, you can only start over, and you have no idea of improvement, but what Zhao Qing said is an understatement, as if it is very simple, which makes it difficult for Weilong to accept.

"Well, how does Zhao Gongzi want to change it." Wei Long, who was red-faced, held back a sentence for a long time, Zhao Qing's previous performance made him really unable to refuse, and people who were engaged in scientific research had an attitude of being more or less humble in their studies.

"I just don't know if the person in this weapons prison is reliable or not, after all, there was a roaring young general leak some time ago." Zhao Qing looked around casually and said.

Hearing this, Wei Long's face also changed, and then he shook his head violently, and said: "It will definitely not be the work of someone in my weapons prison, if there are internal ghosts here, then Ningjiang Prefecture would have changed hands a long time ago." ”

Although he said this verbally, Wei Long still did not discuss with Zhao Qing in front of his colleagues, but took Zhao Qing to a hidden room, and called an old craftsman according to Zhao Qing's request.

This old craftsman is his predecessor, absolutely reliable, and his skills are also extremely high, which just meets Zhao Qing's requirements. Yang Duwei is not good to enter again, he has already left, and there are only three people in this well-equipped room at the moment, Zhao Qing, Wei Long and the old craftsman.

Looking at this sturdy old man, Zhao Qing didn't know why he remembered Song Ci's old boy, shook his head, hugged his fists and said, "Under Zhao Qing, I have seen my predecessors." ”

"Haha, Zhao Gongzi doesn't have to be polite, Guigu is superb, in terms of firearms knowledge, it should be me who calls you senior." The old craftsman was very modest, and actually got up and bowed to Zhao Qing.

Zhao Qing hurriedly got up and helped the old craftsman up, and even called his sins and sins. The two of them sat down again on either side of the wide iron platform.

Zhao Qing didn't come here to chatter, the three of them quickly got to the point, Zhao Qing dismantled the Roaring Boy, took out the copper barrel, and said to Wei Long and the old craftsman: "The Roaring Boy is really not good to make changes in other places, but this barrel can still be improved, the inner wall of this barrel is rough, and there is no stable trajectory of the lead bullet, which causes the Roaring Boy to hit low, but the predecessors of Guigu have already solved this problem, that is, to engrave rifling on the inner wall of the barrel." ”

"Rifling?" The old craftsman and Wei Long were puzzled, especially Wei Long, who had heard Zhao Qing say the name rifling that day.

"The so-called rifling is the pattern engraved on the inner wall of the barrel, in a spiral shape, like this." Zhao lightly lowered the barrel of the gun and drew a spiraling curve on a piece of paper on the iron platform.

The old craftsman and Wei Long are both insiders, and they can understand the meaning of Zhao Qing's drawing at a glance, and when they look at each other, they both see a trace of surprise in each other's eyes, this kind of rifling can really solve the problem of accuracy of the roaring young general that has plagued them for a long time.

But soon, they showed embarrassment, the old craftsman lay on the iron platform and looked at the drawing for a long time, raised his head and said: "Sure enough, it is worthy of the idea of the master of the Guigu Valley, this method gathers the gunpowder momentum in the chamber and does not disperse, and the spiral pattern implies the principle of Yin and Yang Taiji, and it is indeed very likely to solve the problem of ballistic instability, but... ”

"Just how?" Zhao asked lightly.

"It's just that this process is too difficult, the roaring young general's barrel is three or one inches wide, and if you want to engrave such a complex rifling in such a thin barrel, not to mention the ordnance supervisor, it is difficult for skilled craftsmen from all over the world to do it, but I don't know how to do it in the Ghost Valley." The old craftsman looked at Zhao Qing.

Of course, Zhao Qing knew, but the tool needed to be built, otherwise he would not have come to the Ordnance Supervisor for help, and said: "You need an iron rod, the iron rod is slightly thicker than the inner width of the barrel, longer than the barrel, carve the iron around the iron into a thread-like shape, the iron is harder than copper, aim the iron rod at the muzzle, rotate the barrel so that the iron rod penetrates the barrel." ”

The old craftsman's eyes lit up after hearing this, and he immediately said that it was feasible, and left the room without saying much nonsense, obviously to find materials, seeing the old craftsman so diligent, Zhao Qing also breathed a sigh of relief, what he was most afraid of was that he said the method, but the craftsmen in the ordnance prison could not operate, and now it seems that the old craftsman is very confident in being able to make spiral irons.

After a while, the old craftsman found five or six iron rods, the thickness and length of these iron rods were very suitable, listening to Wei Long's statement, these iron rods were originally used to polish the inner wall of the barrel of the roaring young general. When Zhao Qing heard this, he hurriedly said that it should be slightly thicker than the barrel of the gun, but it attracted the strange eyes of Wei Long and the old craftsman.

The old craftsman explained that copper and iron are tough, and that if an iron rod is carved into a screw, it will definitely be thicker than before, and that the width of the inner wall of the barrel will be reduced after the iron rod passes through the barrel and leaves rifling on the inner wall of the copper barrel.

Although Zhao Qing was not confused after hearing this, he couldn't help but show embarrassment, his major is in chemical engineering, and he only has more common sense about mechanical materials, but he is far from being proficient, so he lost a big face in front of the two ancient people who were proficient in this way.

The old craftsman didn't react, but Wei Long looked at the embarrassed Zhao Qing intently, with a smile on his face, obviously he had discovered that this Guigumen man was just a person with empty theories and no practical experience, which made him find some comfort from his previous frustration. Zhao Qing's performance at this time was more in line with his age.

Wei Long and the old craftsman each took an iron rod, clamped it on a fixed device that was common in later generations on the iron platform, and then took out two handmade knives and processed them along the iron rod.

"Tungsten Knife?" Zhao Qing raised his eyebrows, he didn't expect that this kind of extremely hard metal had been developed in ancient times, no wonder the old craftsman and Wei Long would be confident that they could finish the iron like that.

"Zhao Gongzi knows this metal? Haha, too, I think there will be no shortage of this rare gold and stone in the Ghost Valley, but this metal is not called tungsten gold in the Great Zhou, but called black iron, and the history of discovery is only more than 100 years, and the hardness is far beyond ordinary iron and copper, but the output is too small to be mass-produced into weapons. Wei Long explained as he engraved.

"There are indeed ones in the Ghost Valley, but it is not this tungsten gold knife that is used to process iron glass, but a diamond knife, a material that looks like glass but is extremely hard. This type of diamond is even rarer. Zhao said lightly.

Zhao Qing couldn't intervene in the next thing, Wei Long always looked at him with a smile from time to time, which made him very uncomfortable, Zhao Qing was very unhappy with this situation of exposing his own shortcomings, and it did not affect the work of the two, so he walked around in this studio.

He found that the studio was actually very dirty, with all kinds of black ash on the floor, and there were many bottles and cans in the corner. Zhao Qing rolled his eyes, and he understood that these were all old thunderbolts recovered by the Ordnance Supervisor, and it was obviously unrealistic to make a large number of new thunderbolts with the current reserve materials in Ningjiang Prefecture, of course, it was necessary to recycle the old thunderbolts, take out the original gunpowder inside, and then replace them with new formula gunpowder.

Thinking of this, Zhao Qing moved his mind again, and the Ordnance Supervisor hurriedly promoted the new gunpowder, and the recovered old gunpowder must have accumulated a lot. Although these are not as powerful as the new gunpowder, it must be reasonable to be able to use them for two hundred years in the Great Zhou, and it is absolutely impossible to be eliminated at one time, such as the roaring young generals and artillery are inseparable from this old gunpowder, the new gunpowder is too powerful, and even the 2,000-pound artillery will explode, which is obviously not suitable for the roaring young generals.

These old gunpowder have been dispensed, it is impossible to turn back into raw materials to mix new gunpowder, then the ordnance supervisor must have accumulated a lot, and his forward right battalion is in urgent need of these, Zhao Qing is already thinking about how to ask for these old gunpowder to supply his musket team.

After waiting for an afternoon, the old craftsman finally finished processing the iron rod, and in order to increase the sharpness of the iron rod texture, he even used a file to polish it carefully, and the spiral pattern bulge on the iron rod was sharpened. Zhao Qing stepped forward to take a closer look, and found that this iron rod simply met the requirements perfectly, the spiral lines on it were very neat, although it was carved out by the old craftsman with a carving knife in his hand, but it was no worse than the drill bits processed by the lathe that Zhao Qing had seen. He couldn't help but glance deeply at this sturdy old craftsman, this kind of craftsmanship can already be called a masterpiece.

After a while, Weilong, who had a few circles of thick body, was finally completed, compared to the old craftsman's face did not change color, this big man was soaked all over, and water was dripping from his beard, Zhao Qing inspected the goods and found that although the lines on it were also neat, it was still a lot worse than the one made by the old craftsman, but it was barely usable.

"Then let's start rifling." The old craftsman's face, which had not changed since he picked up the carving knife, was also a little excited, and he pushed away Wei Long, who looked exhausted, picked up the barrel of the roaring young man, aimed it at the drill-like iron rod fixed to the fixed frame, and poked it in.

The processed iron rod was really a little thicker, and it was just right to pass through the barrel, but at this moment it was resisted as soon as it touched the mouth of the barrel, and the old craftsman's face sank, and the arm full of strong muscles was forced, and he grabbed the copper barrel and slowly rotated it and pushed it in, like a screw, although the force used was great, but the barrel was always aimed at the straight drill-like threaded iron, and it was not skewed at all.

Time seemed to have passed a century, looking at the barrel slowly inching in, Zhao Qing and Wei Long did not dare to make a sound, for fear of affecting the old craftsman's hand, if there was a slight tremor at this moment, they would all lose their efforts.

Finally, all three were relieved to see the drill bit of the threaded iron come out of the other end of the barrel.
