"You don't know where to put these things, or you could have done it faster. Tianyou said as he pounded the iron bar in his hand, and his speed did not decrease at all.

Kuroko leaned over and looked at it twice, but couldn't recognize what it was, so he asked, "What are you doing here?"

"Bow blades. ”

"What is used on the bow?" Kuroko didn't know what a bow was, but since he had a bow word, it would be eight or nine and ten.

Tianyou nodded. He hammered it twice more to see that it was about the same shape, and threw the red-hot iron into the oil tank.

There was no snorting sound as expected, and the solution in the oil tank was simply tumbling and calming down, but it was manifested as a large cloud of smoke and a rather unpleasant smell.

The guys and craftsmen in the shop began to arrive one after another, and they were very curious to see Tianyou doing things, but there were sunspots there, and they couldn't ask directly, so they could only ask what sunspots were doing. Kuroko could only shake his head, because he didn't know what Tianyou was doing. Separately, he could see everything that Tianyou did, but when it came together, he couldn't understand it at all.

After finishing the work in hand, Tianyou was finally idle, and Kuroko took the opportunity to go up and ask a bunch of questions, but unfortunately Tianyou's answer was equal to not listening, because he didn't understand it at all. Tianyou also knew that Kuroko would definitely not understand, so after a brief explanation, he talked about the issue of money.

The materials are definitely not enough, and last night the firewood alone burned a pile the size of a room, and the iron ore and wrought iron were not counted. However, Tianyou didn't plan to pay, because he planned to sell the bellows technology to Baibingfang.

This shop belongs to Lu Meng, and the relationship between the two is quite good along the way, so Tianyou doesn't mind selling this kind of technology that doesn't matter to him. Anyway, the technical content of the bellows is really not high, even if God blesses it and doesn't sell it, people can figure it out if they look at themselves.

Kuroko had seen the power of this bellows last night, and Tianyou said that he wanted to sell the whole set of technology, of course he was in favor, but because he had seen the power of this thing, he couldn't call the shots. This bellows is too important to the blacksmith shop, and he feels sorry for the less money given, but if he gives too much, he doesn't dare to make the decision casually, and he always knows that Lu Meng will do it.

Anyway, Tianyou wants to stay in the royal city for a while, so there is no rush in this matter. Heizi promised to communicate with Lu Meng as soon as possible, and he also directly waived the material fee of Tianyou, anyway, compared with the bellows, it was all small money.

Entrusting the stove to the old horse to watch, Tianyou and Kuroko went to eat some breakfast together, and when they came back, they just opened the furnace and took out the parts inside.

The strange-shaped parts were put on the stone slab for natural cooling, and Tianyou did not use any auxiliary cooling tools. This batch of parts has actually been quenched last night, and when the sunspot woke up in the morning, the parts he saw were all in a low-temperature tempering state, in order to remove the internal stress of the metal. This process reduces the hardness of the metal, but at the same time reduces the thermal brittleness of the metal and increases the toughness.

When Tianyou processes these parts, the material characteristics are similar to spring steel, and the toughness and yield resistance are required instead of hardness, so they need to be tempered.

Relative. Instead of tempering, the arrows are quenched in two stages in order to maximize the hardness of the material.

The performance of steel mainly depends on the use, Tianyou has a variety of precise formulas of alloys, although he can't get such an accurate ratio now, but he can at least adjust the ratio of materials and smelting methods according to his own wishes, which is also the main reason why Tianyou's weapon performance is so outstanding.

The natural cooling rate of the metal is very fast, and the tempering does not need such a high temperature, and the temperature of the furnace mouth selected by Tianyou is about 200 degrees, and these iron parts will quickly cool down naturally even if they are not treated with special treatment at this temperature.

After an hour, all the parts are close to normal temperature, at least they can be touched directly by hand. Without waiting for the things to cool down completely, Tianyou took out his compound bow from the carefree bag and began to disassemble the parts.

Although it is necessary to remake a bow, there is no need to recustomize all the parts, at least the bowstring and eccentric wheel can continue to be used. If it weren't for the lack of standardized equipment and the inability to customize the screw holes, Tianyou could have made a new bow with just two bow blades.

Before, the people in the store couldn't understand the things that Tianyou created, but everyone could at least recognize what this bow was for, and it was this strange structure that people couldn't understand.

Tianyou didn't leave them much opportunity to observe, and quickly dismantled the original bow, and then began to assemble the new one. The bow handle is still the original one, replace the two newly completed bow pieces, adjust the angle, insert the adjustment bolts, do not tighten it first, but install the pulley block and bowstring, and wait for the bowstring to be in place and then tighten the bolt to tighten the bowstring.

In less than a stick of incense, Tianyou assembled the new compound bow, but this was not the end, because the new bow was not accurate and needed further tuning.

"Brother Hei, do you have an arrow target here?"

"Arrow target?" Kuroko shook his head and said, "We don't sell bows and arrows, even if we need to test weapons, at most we use scarecrows and wooden men." ”

"Wooden people are fine, too. ”

"I'll get it for you. ”

Soon a wooden figure was erected, but it was said to be a wooden man, but in fact it was just a cross made of thigh-thick logs. Tianyou asked Kuroko to help find a few ordinary bows and arrows, and Kuroko quickly found two feathered arrows with iron arrows from the blacksmith shop across the street.

After getting the arrow, Tianyou did not immediately test the shot, but first tried the bowstring back and forth a few times, and then pinched an adjustment rod at the front end of the bow body, pulled and pushed, re-locked, and tried twice, and only then picked up the feather arrow and put it on the arrow platform after feeling that it was almost done.

10. The courtyard where the centipede furnace is placed in the arsenal is a long and narrow space, which is just used to test the bow and arrow, of course, it is impossible to measure the distance, after all, the store cannot be so big.

Standing at one end of the courtyard, Tianyou holds the spreader in his hand, buckles the D-ring with the front jaws, raises the bow, pulls it apart, and aims at the opposite wooden man through the crosshairs.

In the morning, there was nothing to do in the shop, and everyone gathered behind Tianyou to watch, looking at the strange bow and talking about it.

"It's strange that this bow has three strings. ”

"What's that in his hand? Why don't you just pull the string and hook it with something?"

"What are those two balls for?"

“......”

Tianyou didn't care about the discussion of everyone behind him, he had heard this kind of discussion countless times. This is the reaction every time someone sees his bow, after all, the structure of the compound bow is so special, it is strange for people to feel strange.

After pulling the bowstring, Tianyou didn't deliberately aim, and just pulled the trigger on the spreader in roughly the right direction. The feather arrow flew out lightly, and as a matter of course it deviated from its target, slamming into the boulder-made wall with a thud, and then ...... Dropped.

Everyone, including Kuroko, was quite surprised. Not because it's too powerful, it's because it's too small.

Just now, Tianyou used the feather arrows of the best iron arrows, and it is said that even if it is an ordinary longbow, at such a close distance, the arrow should be able to be embedded in the wall. Even if it can't be hung, it should leave some marks, but the arrow just now didn't even leave a white spot.

With such a complex bow and so much power, what is he doing with it? Wouldn't it be better to use the simplest horn bow?

The discussion behind gradually became louder, but Tianyou didn't hear it at all. Adjusted the improvised sight on the handle of the bow up a bit, then re-locked it, picked up the second arrow, and tried another arrow.

Quiver...... This time, the feathered arrow hit the wooden man's head accurately, but the arrow was only embedded in the fingernail and stuck there. Because of the lack of depth, the tail of the arrow quickly collapsed, and then it fell to the ground with the arrow in tow.

In the past, it was better to say that the stone was too hard to shoot in, but what was the matter if it couldn't even shoot into the wood? Is this kind of rag really a bow? Isn't it a toy for children to practice arching?

At this time, even Kuroko couldn't sit still, and ran over to ask Tianyou what was going on, if there was a problem with the parts made last night. Tianyou smiled to reassure him, then went to retrieve the feather arrow, adjusted it and tried to shoot it again, this time it still hit, but it still failed to embed itself in the wooden figure. The fourth arrow was the same, it accurately hit the shallow mark left by the third arrow, but it still couldn't hang up and fell off on its own.

Two arrows to try to play, and some people in the onlookers behind them have already begun to make nonsense to assert that this thing is useless, but Tianyou just laughed it off.

Open the adjuster in the center of the bow handle, pull back to the previous position, and lock it again, Tianyou tried the strength of the bowstring again, and felt that it was still almost there, so he adjusted the two ends of the newly made bow blade again.

Preparing the compound bow, Tianyou did not immediately start testing the arrow, but ran to the side of the wooden man, took a damaged shield, and hung it on the wooden man's body. Thinking about it, he still didn't feel at ease, so he went to the pile of materials that had been scrapped and took out a thick iron plate that was not in shape and put it behind the shield.

After all was done, God blessed him and returned to his original position. Instead of using the previous feather arrows, he took out the armor-piercing arrows he had made from the oil tank. Dry the surface and re-pose. Inhale and exhale, and suddenly raise the bow at the same time as the second inhale, and exert force on the waist, back, arms, and chest at the same time. The bowstring, which could be easily pulled away before, trembled this time, and almost failed to pull it completely. Tianyou's face was flushed before he finally let the apex of the eccentric wheel pass through the critical position, and then Tianyou felt that the bow force suddenly lightened, and he was instantly pulled to the full moon state.

The biggest difference between a compound bow with an eccentric wheel and a traditional bow is this, once the apex of the eccentric wheel passes the critical position, the pull of the compound bow will drop sharply, so it is far less labor-intensive to pull a compound bow with the same pull than a normal bow. Also, when the compound bow is fully open, only a small amount of force is required to keep the bow open, allowing the shooter to focus more on aiming rather than maintaining the open.

Everyone had seen the power of this bow before, and the four arrows in front of them didn't even shoot into the wood, and they didn't understand why Tianyou put a shield on the wooden man, and he also put an iron plate on it. What's even more strange is that it was obviously very easy to see Tianyou open the bow before, but this time it somehow became so difficult.

The crowd didn't understand, so they could only watch patiently. However, there is no shortage of capable people in the 100. After hearing his apprentice's questions, a master said uncertainly: "The mechanism that this little brother just adjusted should be used to adjust the tension of the bowstring, but I don't understand how he put this kind of thing on the bow." Judging by the struggling appearance of his bow when he first opened it, the power of this arrow should be far greater than before. ”

"Really?" the apprentice was still asking, but Tianyou suddenly pulled the spreader.

I only heard the sound of a bowstring trembling, and it felt as if there was no interval at all, and at the same time as I heard the sound of the bowstring, the wooden man on the opposite side had already flown backwards, hitting the wall behind him with a bang, and then rebounding back and falling to the ground, splitting apart in an instant.

A lot of people are taken aback because they weren't prepared, but the people who were really scared weren't here.

After the start, it took a while for everyone to react.

"Oh my God! what just now?"

"Didn't the previous few arrows have no power? Why did they suddenly become so powerful?"

"Go and see the target. ”

Finally, I had a quick reaction and remembered to go to see the target, and then a few guys with quick legs and feet ran over first.

Turning over the wooden man that had been broken into several sections, a few guys looked around on the ground and couldn't find where the arrow was.

"Strange, what about the arrow?" one of the fellows looked around and didn't see the arrow, so he simply picked up the shield.

The center of this shield was slashed, and it was about to be broken, but the upper and lower halves were basically intact, and the defense power had not decreased much. But when the man picked up the shield, everyone couldn't help but gasp, because everyone saw the big hole in the shield.

"Oh my God!

"This is the special shield for the squad leader ordered by the Yulin Army!

The crowd was still talking about it, and a guy over there picked up the piece of iron that was underneath, and as expected, there was a flowering hole in the sheet, and it felt like something had exploded. Looking at the wooden man again, the chest position has been completely shattered, and it seems that the wooden man fell apart before. The wooden figure used for the knife test itself is also very strong, and it is impossible to fall apart casually. The reason why it shattered so completely was because its interruption had been completely shattered when it was hit by an arrow, and it would be scattered all over the ground.

The shields, the pieces of iron, and the wooden figures were shot through, and the eyes of the people unconsciously moved to the wall, and as a result, everyone saw a round hole, and there were no arrows on it. Now everyone really couldn't be calm, and a group of people in Hula ran to the front yard, even Tianyou. He's afraid of shooting people!

The bow was made by him, and of course he knew the power, so he deliberately padded a shield and an iron plate, but he didn't expect the power to be so great. Even if they shot through the shield and iron plate, even the stone wall of the Hundred Soldiers could not block the residual power of the armor-piercing arrows. The hole in the wall was completely clear, indicating that the arrow had not been caught in the wall, but had passed through.

Inside this wall is the storefront of the Hundred Soldiers, and if the armor-piercing arrow flies through the store and into the street, it will be really dangerous.

A group of people rushed to the front store, and then found the guy who was supposed to be watching the store squatting behind the counter with a frightened look, and the weapon displayed on the shelf behind him fell to the ground.

Look further. The weapons in the shop were fine, but no one could see where the arrow was.

Tianyou was blocked by the crowd, and he had just run into the front storefront, but before he could see the situation clearly, he heard a bang, and the door of the Baibei Workshop was kicked open.

"Which bastard did this?" an angry roar exploded in the doorway. Everyone followed the prestige but almost burst into laughter. I saw a middle-aged man at the door, who was protected by the stars and the moon, with a hairpin nearly two feet long on his head. Take a closer look, what kind of hairpin is this, is it clearly the arrow they are looking for!
