Qi Jiguang was surprised at this time, since you can't help with artillery manufacturing, what do you mean by helping?

His mind was racing, and he said secretly: Could it be that Gao Shiyu means that the elder of the Gao Pavilion and even the emperor will allocate an extra part of the silver to our Jizhen for the development of new artillery? Well...... That's another way to help, but can he really help with this kind of thing? The use of the imperial court is not sufficient, not to mention that the elder Gao Ge is now checking and filling the gaps in all aspects, in order to smooth the deficit of the imperial court and plug the loopholes that some previous appropriations were abused. Then it is even more impossible to raise the salary of a certain military town casually - take 10,000 steps back and say, even if you really want to raise it, shouldn't you raise it first on the side of Xuanda? Over there, I came to directly face the most threatening Altan Khan, and secondly, I was also the descendant of Gao Ge Lao, and they didn't have the turn to raise salaries, where would I have a chance in Jiliao?

But Gao Pragmatic's words made Qi Jiguang puzzled, because Gao Pragmatic said: "The main focus of this help is the artillery truck." ”

"Gun carriage?" Qi Jiguang deserved to be Qi Jiguang, and he immediately asked: "Gao Shishu is good at making cars?" Do you mean that it is possible to create a better gun carriage to act as a mobile gun mount for artillery, so that artillery can move more quickly, and improve the ability to mobilize and deploy in formation? ”

"Qi Dudu is really good, but you are only half right." Gao pragmatic smiled: "I do have a way to increase the movement speed of the gun truck, but it requires a very critical part, but that thing not only needs steel, but also needs to be very precise manufacturing." In addition, once that thing is made, it can be used not only by the gun carriage, but also by many engineering tools, far more effectively than any existing method. ”

Qi Jiguang no longer thinks that Gao Shishi is a little fart kid who can brag about it, and when he heard this, he not only immediately became serious, but asked solemnly: "I don't know what Gao Shiyu said?" ”

"This thing should have never been seen before, and I didn't mention it in the manuscript album I gave to Qi Dudu last time." Gao Shishi took a deep breath, sat up straight, and said, "I named it 'Bearing'." ”

"Bearings?" Qi Jiguang frowned, he couldn't think of what it was, and he couldn't help but be a little difficult to speak.

Gao pragmatic smiled: "I'll show you a simple painting...... Gao Mo, take a charcoal pencil. ”

Although Gao Pragmatic is different from many traversers, his brush writing is really passable because he has practiced since he was a child, but being able to write calligraphy does not mean that he can paint with a brush - he has not learned this, but he was forced to learn a few sketch classes in middle school, so when he came this time, he specially prepared a few charcoal pens that seemed to him to be so simple that he wanted to cry, and he used it for a while.

Qi Jiguang didn't dare to underestimate Gao Pragmatic, and took Gao Pragmatic "painting" seriously. He soon discovered that Gao Shi's painting style was extremely different from that of previous dynasties, especially his mastery of the shadows of geometric figures was exceptionally pure, and after a complex ring-shaped object was drawn in his hands, it was almost like a real thing in front of him, especially the sense of hierarchy was extremely strong.

If Gao Shishi knew that Qi Jiguang had wandered into this aspect, he would definitely tell him: This is all pediatrics, but it is just an incidental skill after practicing sketching and drawing eggs back then, let's not go off topic.

In the end, Gao Shishi drew a ring with an inscribed edge, a circle of small beads in the ring, and another small ring inscribed on the opposite edge of the foreign minister's ring.

"This kind of can be called a ball bearing." Gao Shishi smiled and said, "Qi Dudu, you can imagine that if this thing is installed on the axle, will the resistance of the vehicle when it travels much less than the current one?" ”

Qi Jiguang didn't answer immediately, but carefully stared at Gao Shishi's sketch and thought carefully for a while, before he sighed: "Gao Shiyu, your intelligence, Qi Mouwei is convinced, although the principle of this thing can be understood even by me, a martial artist, but such a whimsical idea, how can there ever be a second one for thousands of years?" ”

Gao pragmatic kept a reserved smile on his face, but said in his heart: That's not necessarily, the Romans have used this kind of thing, but the metal smelting technology of their time is even more inadequate, so they just made some wood products, and then Da Vinci, the real genius, and has a new idea for bearings, and finally when the level of metal smelting comes up, Westerners will suddenly lead the world in this regard. I haven't started sailing yet, and I can't get books like geometric originals, but the ancient Chinese were especially good at handwork, so although the bearing is complicated, I can design it first, and then force it to rely on the excellent manual skills of skilled craftsmen to grind it out, but ...... Iron smelting and steelmaking must wait for my steel plant to dry, otherwise with the current smelting level of Daming, even if the bearings are made, the durability will not meet my requirements at all.

Although Gao Pragmatic was thick-skinned, he couldn't stand Qi Jiguang's constant praise, so he coughed dryly and changed the topic: "Qi Dudu, I have already drawn the appearance of this thing, but with the current steelmaking technology, even if it is manufactured, it will not achieve my ideal effect, so I bought land in Kaiping, planning to use the iron ore and coal mines near Kaiping to make steel, and then start manufacturing it myself." ”

Qi Jiguang was surprised: "I know that there are some iron mines near Kaiping, but the coal mines are ...... Although it seems to be a lot, as far as I know, it is impossible to make good steel from coal mines...... Is there another way? He originally wanted to say, "I'm afraid you'll be disappointed if you do this", but suddenly it occurred to him that with a ghost like Gao Pragmatic, can't coal be made into good steel? Knowing that he has to do it means only one thing: he can solve the problem.

Sure enough, Gao pragmatic waved his hand: "I can solve this problem, but it's too late to talk about it now...... Let's start with the second area where the gun carriage can be improved - this time it may be more direct than the improvement of the gun carriage with bearings, because this method can directly improve the combat capability of the artillery. ”

Qi Jiguang was surprised and delighted, and was surprised that Gao Pragmatic's brain didn't know how to grow, and improving the artillery carriage could actually improve the combat capability of artillery? The gun truck itself is just a carrier, what does the change of gun car have to do with combat capabilities?

The good news is that if Gao Pragmatic's words are true, then this effect can be immediately strengthened to the existing artillery, isn't it wonderful?

Without saying a word, Gao pragmatic picked up the charcoal again and drew on the paper.

This time, he drew the rest of the gun carriage very briefly, but at the lower position of the front of the gun carriage, he carefully drew a device that Qi Jiguang had never seen before, that thing was like a pillar, and some words were marked on the column, which looked like a scale on a ruler, and the top of this cylinder was a longitudinal semi-cylindrical concave.

Qi Jiguang looked at it seriously, and suddenly his heart moved, and he blurted out a sentence: "The role of this thing is to hold up the muzzle?" ”
