Meng Huan Chilong heard that Tian Zhikun was praising him, but he didn't understand what the other party meant, and looked straight at Tian Zhikun. "Mr. Tian, what are you talking about! I don't know anything about blacksmithing, and I'm going to ask you. ”

Tian Zhikun shook his head with a smile and said: "A good caster, imagination is very important, only by imagining something different can it be called ability, you are such a person." Just said that the wooden pole is equipped with a metal spear tip, not only to reduce the material and production time, easy to carry, but also the lethality is not weaker than the iron crossbow spear, the disadvantage is that the distance is worse, but it is much better than the wooden spear. ”

He listened to these words and opened his mouth, in fact, this was what he had thought many years ago. There are no metal arrows in the mountains and forests, only wooden arrows and bamboo arrows, but this kind of arrow is not sharp enough, and there is no accurate head at a long distance, so I want to install a sharp metal arrow on the wooden arrow, which is also good, at least it can shoot far, and it is easy to shoot through the mountain beasts with thick skin and rough flesh.

"This is actually my original idea, and I just said it casually. Didn't you just say that wooden spears are easy to rub in flight and cannot be well balanced?

"I just thought that this kind of arrow is much easier than making an iron crossbow spear, and it is cheap and short-lived, and it can be used as a disposable arrow. ”

Hearing this, Meng Winding Chilong was very happy, at least what he wanted could be realized. "That's great, so there are enough arrows. No, it's a crossbow. ”

Tian Zhikun smiled bitterly: "It's not so easy, the weapons of our soldiers are all smashed by craftsmen one by one, and the production time is long, so they can't keep up with the training wear and tear in peacetime, and now it's even more troublesome in wartime." I think you're a good idea, as long as you make the spear point, you can save the blacksmith time. It's just that the weight of the spear tip and the wooden pole is another problem, and only by trying a few more times can you find the exact ratio. ”

"Why? Is it that no one wants to be craftsmen now, so we don't have enough manpower?"

"This is one reason, and the other is that there is no ability to make standard instruments in batches, and the metal products are all hammered out, although the quality is guaranteed, the production time is long, and to make exactly the same thing, the craftsmen have to do it with experience, and sometimes a little heavier hammer has to start all over again. ”

He understood, and said: "I have seen a slender and long sword of the Duanzheng Dynasty, it is said to be called a stabbing sword, it looks the same, I think their soldiers are each equipped with one, do they have the ability to make standard instruments?"

"There should be, as far as I know, there are many casters in the Angel God Kingdom and the War Clan Country, and their weapons are the best in the whole continent, and when I studied in the War Nation Country, they had the ability to make them in batches. ”

Meng Winding Red Dragon had a lot to ask, such as why those two countries produced forgers, but he still asked what he wanted to know the most.

"Mr. Tian, you have been in the Warring Clan Country, do you know this method of mass production?"

Tian Zhikun shook his head silently. "I don't know, you know, I already did it. At that time, this kind of process was not shown to outsiders, I just heard that it seemed to be poured out of some mold, but I didn't know the details. ”

"Mold?" Meng Huan Chilong listened, and walked around the workshop a few times, because he was familiar with this thing.

I remember when I was a child, when I celebrated the Wu Nationality National Celebration Festival in the mountains and forests, my grandmother would make pastries for them, and every time before making them, my father would carve some different molds out of wood, and then my mother kneaded the dough, pressed the mold down, and then put it on the stove to bake, it became a beautiful pastry, and he and my brother liked this kind of pastry the most.

When he thought about it, his eyes lit up, and if he made a crossbow spear mold and then beat the red-hot metal into the mold, would there be a crossbow spear, but he remembered that no matter what shape the pastry was, one side was always flat, and that made the pastry mold easy to make, and the crossbow spear mold was not easy to make. Because the shaft of the crossbow spear is round, but the spearhead is triangular.

He hesitated, looked at Tian Zhikun and asked, "You know that it was poured out of the mold, have you ever tried it in this regard?"

"I've tried, and many people have tried, but I can't solve the things made by the mold, and one side must be flat, otherwise the things inside can't be taken out. ”

He knew what Tian Zhikun meant. "Looks like you've tried, but I don't know what you think?"

Tian Zhikun shook his head helplessly, and said: "I have tried many times, but I haven't made this kind of mold, so I remembered that I had seen a furnace in the Warring Clan Country, so I got one myself, which helped me save a lot of effort." ”

"What is the stove for?"

"Metal ores have to be burned on fire, and impurities are hammered out to form metals. After hearing about the mold, I thought that the earth could make gold, and I used stone to make the mold, but I didn't expect it to be useful. It's just that the metal is cast into the mold, which is a troublesome thing, so it is much more convenient and faster to think of the furnace, melt the ore into water, remove some impurities, and wait for a little cooling before forging and refining. ”

"Heh, it looks like the stove is made, what kind of stove?" This made him a little curious, thinking what kind of stove can make hard metal into the shape of water.

Tian Zhikun said proudly: "The matter of the furnace is naturally done, do you want to take a look?"

He was intrigued, and naturally wanted to see a furnace that could boil metal into water. He swept around the workshop, but saw no stove.

"Mr. Tian, where is your stove?"

"Come, go inside. Tian Zhikun pointed in one direction in the workshop, and then walked over.

He followed Tian Zhikun until he walked to the innermost part of the workshop, and saw a rectangular box more than a zhang high standing in a corner, and the whole box was made of refractory stone.

This kind of refractory stone can only be found in the earth fire, or the eruption of the earth fire, and these stones are tempered by fire and are no longer afraid of fire burning.

The fire pond in the mountain is enclosed with this kind of stone, and this kind of stone is common in the mountains and forests, and it seems that a pile will emerge somewhere, maybe this place was originally the mouth of the ground fire. This stone is grayish-white, lighter than ordinary stones in the hand, and has a smoother surface.

And the box is divided into two layers, the upper part is the place where the metal is smelted, there is an obvious discharge port, which is the discharge of the metal that is burned into liquid, and the lower part is the place where the fire is generated, the whole principle is similar to the medicine tripod, but I don't know what this big box is used to burn, if you use the fire attribute yuan qi stone to burn, how many yuan qi stones do you have to use?

He looked at it carefully for a while, and asked with some curiosity: "Mr. Tian, what is the stove used to burn?"

Tian Zhikun narrowed his eyes and said a little slyly: "Hehe, didn't you learn the formation from Master Lei?

He looked around and found that there was a formation in this corner of the workshop, which, according to his memory, should be the fire gathering array on the "Divine Array Record".

"Gathering fire?" he blurted out.

"I can see it, then I should know what it was burned with? This is what your master helped me build. ”

Meng Huan Chilong thought for a while, and felt that there should be earth fire here, and only earth fire could destroy this array and produce flames, which could save the cost of burning and smelt those metals.

He patted the big box and said, "Mr. Tian, this box is the only one that wants to come to the Wu Clan, right?"

Tian Zhikun laughed proudly, held his head high and said: "I don't have this knowledge, the name is given by Master Lei, it's called the Burning Gold Forging Furnace, how about it?" ”

He reminisced for a moment and said, "The name is not only atmospheric, but also in line with the role of the stove, which is really good." My master has been thinking about it for a few days. ”

Tian Zhikun laughed out loud when he heard it, probably remembering what funny things happened when he was named at that time. And the words of Meng Winding Red Dragon themselves are also joking with the master.

In Tian Zhikun's laughter, the red dragon's gaze fell on a few stones by the stove. It was a few large refractory stones, and now there are square, elongated, and circular holes dug on the refractory stones, which were used by Tian Zhikun to make molds, but they didn't succeed.

He crouched on the ground, looked at the refractory stone on the ground, and then looked at the crossbow spear in his hand, and suddenly his eyes lit up, and he quickly stood up.

walked to Tian Zhikun's side, pointed to the crossbow spear in his hand, and said, "Mr. Tian, although the tip of the crossbow spear is triangular, if it is changed to a flat shape, it will become symmetrical." If you open the mold in half according to the crossbow spear, and then try to put the two molds together, isn't it still a complete crossbow spear, and then pour molten iron into it, can you get a crossbow spear?"

Tian Zhikun was stunned for a moment, and then immediately smiled: "Sure enough, he is a genius, he should indeed be a caster, and he can come up with ideas so quickly, I thought about it for a long time before I thought of this method, but I can't solve one of the key problems, so I can't do it." ”

"What's the problem?" asked the red dragon instinctively.

Tian Zhikun scratched his head and said: "That is, after the two molds are combined, when the molten iron is poured into it, the molten iron will leak out from the joint of the two molds, which also deforms the things made, which is not only a waste of molten iron, but also troublesome." ”

Meng Huan Chilong frowned, thought for a long time, and suddenly remembered something. "Mr. Tian, I'll show you something. ”

As he spoke, he took out the box that contained the exercise book in the storage bag from the storage bag. "This is the box of the Righteous Dynasty, what do you think?" he opened the lid of the box.

Tian Zhikun took the box and looked at it carefully, and found that the two sides of the box lid were not flat, but had opposite concave and convex surfaces, so that after the box lid was closed, it could be tightly sealed, and there was no gap between the two sides.

You must know that the jade bottle that the Wu Clan Kingdom now holds the elixir does not have a bottle cap, but is only sealed with wax or cloth strips. So Tian Zhikun looked at it for a while before he understood.

This made him very excited, and said, "I've seen such a box, why didn't I remember it." Actually, it's very simple, why am I so stupid. Don't be in a hurry to leave, I'll come when I go. Saying that, he found someone to go to Zhang Luo and left Meng Huan Chilong in the workshop.

In fact, there are a lot of things in this world to understand, they are all simple things, but there are very few geniuses in this world, you haven't seen it, or you don't know it, then no one will think about it, and naturally you don't know.
