The second craftsman's room: Qin Jianfang.

In the blink of an eye, everyone entered a huge craftsman's room, only to see that half of the thousands of craftsmen were pouring bronze and tin proportionally in the high-temperature furnace fire, and the other half were "ping pong" to build all kinds of long swords.

Everyone's eyes suddenly lit up, you must know that there are only two kinds of good swords in most of the present: one is the stainless steel long sword made of precious meteoric iron, and the other is the super long bronze sword produced by the Qin State. Meteorite iron swords are extremely rare, rare in the world, and they are worth thousands of gold, and many meteorite iron swords made by famous teachers such as cadres and Mo Ye are even more difficult to find; And the Qin State has extremely strict control over weapons, and ultra-long bronze swords rarely flow into the people, so everyone can't help but be very excited to see the casting process of this super-long bronze sword with their own eyes now.

Everyone gathered around a few craftsmen who were concentrating on building bronze swords, and they didn't bother, just watched quietly. Although the craftsmen saw Fusu and others, one did not know who it was, and the other was subject to strict military law, they did not dare to stop for a while, and only buried their heads in their work. Fu Su and the others watched it for a long time, but they were just at a loss, and they couldn't see why Qin Jian was sharp in the world, and at the same time, the length was actually in the world.

Fusu, who had no choice, had to go to the side of the weapon rack and take down a half-finished bronze sword that had just been cast, and looked at it carefully. There is a way that 'insiders look at the doorway, laymen look at the excitement', Fusu looked at it for a long time and shook his head depressedly, nothing was gained, and the nine people who were not injured seemed to be thoughtful, but there was also a glimmer of confusion in the excitement, it seems that they only know one of them, and they don't know the other.

Fusu then asked depressedly: "Engineer, why is it that the bronze swords of the Six Kingdoms of the Kwantung Kingdom can only be within two feet six inches (sixty centimeters), while the bronze long swords of my Qin Kingdom can be more than four feet (ninety centimeters) long, what is the reason?" Seeing that Fusu was puzzled, he couldn't help but proudly say: "Of course, my country's bronze sword casting technology is the most advanced in the world, and there are secrets that are not passed on." Childe, please see! Then he explained it to the people.

"To cast the best Qin sword, the mixed ratio of bronze and tin is the key. I have already told Gongzi just now that the hardness and flexibility of the gold water will reach the most perfect level under the ratio of four parts bronze and one tin part, which is a prerequisite for whether Qin Jian is sharp or not. And if you want the Qin sword to exceed the general norm and reach more than two feet and six inches, the secret lies in the shape of the Qin sword, please see, Childe: there is a length of two inches and two from the hilt to the blade of the sword, which is called the sword grid. It can be seen that the sword grid is wider and thicker than the rest of the place, and this design is to enhance the firmness of the foundation of the sword body; From the sword grid to the blade, the blade of the blue leaf gradually narrows, with a vertical apex angle between the two blades, and the sword body has eight sides. This is followed by a concave corset, which gradually widens after that. Among them, the girdle is very important to the length of the two-edged and eight-sided Qin sword, which can act as a 'wind trough', thereby enhancing the speed and power of the assassination. At the same time, the thickness of the sword body decreases where it is wide, and the thickness of the sword body increases where it is closed, and the degree of width and thickness can be said to change in the opposite direction. This complex shape can not only strengthen the force part of the Qin sword, but also maintain a certain degree of elasticity, and at the same time, the sword body will not be too heavy, which is extremely conducive to hand-to-hand combat. This is why my Qin Jian can be more than four feet long for the top-secret technology! ”

"Oh! I see! Everyone had an understanding expression: It seems that Qin Jian's manufacturing technology is really complicated! Fusu then took the semi-finished product of the ultra-long Qin Sword beside him, aimed at a piece of waste wood beside him and slashed it with a sword, and the sword broke with a "click", and the wooden block more than two inches thick was so fragile under the power of the Qin Sword, you must know that this is not a complete finished product. Fusu and his party couldn't help but be a little stunned.

"Good sword, good sword, not inferior to the ordinary meteorite sword!" Fusu and everyone were full of praise. If it weren't for the fact that Fusu now had the 'Hao Cao Sword', he would have gone to great lengths to get a few of the best long swords from here and bring them back. Fusu suddenly thought in his heart: When Jing Ke assassinated the King of Qin in history, it is said that the King of Qin pulled out a bronze long sword and hit Jing Ke seriously injured and fell to the ground with only one blow, which shows the advantage of the bronze long sword fighting. Obviously, the current ultra-long bronze sword of the Qin State has reached a perfect combination of the length, hardness and toughness of the bronze sword, and the attack power has naturally reached the point of almost perfection! Strong, majestic Great Qin, iron-blooded hero!

After everyone reluctantly browsed the Qin Sword Craftsman's room again, they followed the words to another Smith's Room step by step, and everyone was looking forward to a new surprise for a while.

The third craftsman's room: the crossbow room.

As soon as they entered the third craftsman's room, everyone couldn't help but immediately feel a lot cooler, obviously this craftsman's room was not built to build that kind of big weapon. Everyone looked up, and sure enough, the thousands of craftsmen in the room were divided into two groups, one making crossbows and the other making arrows. Everyone immediately thought about it, the essence of the Qin crossbow is also in the world, what kind of secret are they hiding!?

The crowd immediately watched from the room. In the southeast corner of the room, Fusu and his party found a row of finished crossbow bows, divided into three types from large to small. The length and width of the small crossbow arm and crossbow are only about forty centimeters; Medium in length and width are nearly a meter; And the large one is amazing, completely in the shape of a heavy crossbow machine, lying there like a group of entrenched tigers.

Fusu came up in spirit, picked up the smallest crossbow, and asked, "Engineer, such a small crossbow can't shoot far, right?" Is it also used by my Qin State? He didn't dare to laugh when he heard this, but said respectfully: "It is indeed used by my Qin State, but this is just a cavalry crossbow." Because it is inconvenient for the cavalry to fight on horseback, it is better to be light, so the construction made this small riding bow and crossbow for the use of our cavalry. Don't underestimate this crossbow, this crossbow can be loaded with one hand and fired, which is extremely simple. And the range can also reach a distance of 150 steps (one step is basically equivalent to one meter). It is very powerful, and our cavalry also completely relies on this crossbow to compete with the rangers of Zhao State! ”

"Oh, I see!" (Today, the words 'so it is' are the most frequently used words by Fusu and others.) In front of the huge and top-secret weapons manufacturing industry of the Qin State, their knowledge is too poor! In order to hide his red face, Fusu couldn't help but look at the cavalry crossbow with great interest.

After looking at it for a while, Fusu picked up the medium-sized crossbow again, this time Fusu didn't dare to pretend to understand anymore, and asked seriously: "Engineer, what kind of crossbow is this crossbow, and what kind of crossbow is it used for?" He replied: "This crossbow is a single-shot infantry crossbow, which is used by the infantry crossbowmen of our Qin State." With a range of up to 300 paces and a distance of up to 300 paces, this crossbow is the sharpest long-range weapon available today! And there are three sub-categories of single-shot crossbows, three-shot repeaters and ten-round repeaters! However, the most used are single and triple crossbows! ”

Fusu nodded, learning a little more knowledge. Then he pointed to the largest crossbow machine and said, "What about this?" He said: "This is called the bed crossbow, one shot at a time, the range can reach up to 1,000 steps, and it is generally used by heavy soldiers for siege and long-range combat." The penetration of this kind of crossbow machine is rare in the world, and within a hundred steps, even a strong oar shield up to two inches thick can be shattered with one blow! Today, only the crossbow machine manufacturing technology of the old Han can be slightly comparable to that of my Great Qin! Everyone couldn't help but take a sharp breath when they heard this. Fu Su said in his heart: "Good girl, so fierce!" If a person is shot with an arrow, it is not dead! It is estimated that within 100 steps, it should be no problem to shoot through three or two people. This is the ultimate long-range weapon of ancient times! ”

Suddenly, Fusu discovered a strange feature of the Qin crossbow. Fusu pointed to a protruding square-like metal object on the end of the crossbow arm and said, "Engineer, what is this?" Shi smiled slightly and said: "Hui Gongzi, this is called Wangshan, which is used by crossbowmen when aiming and shooting!" "Dizzy, Fusu is sweating wildly": Qin's weapons have reached such an advanced level that they even have sights. It's not a dream! ”

Fusu's eyes widened, and he opened his mouth wide and asked, "Then how to aim?" Shi smiled and said, "Childe, please see, there are six eye-catching black lines on this infantry crossbow, which are used to estimate the distance of the shot." When firing, the crossbowman estimates the height of the bow according to these six black lines, and then shoots the arrow in an arc. Finally, hit the enemy soldiers accurately. These six black lines are: 50 steps, 100 steps, 150 steps, 200 steps, 250 steps, 300 steps! ”

Everyone is stupid, so powerful! No wonder when Zhao Kuo personally led the army commander Ping to break through the siege, history said that the Qin army's arrows were like rain, almost hitting the arrows, and even Zhao Kuo was shot to death in front of the battle. It's really that powerful!

Seeing that Fusu and the others were stunned, Shi obviously continued with a smug face: "Actually, this Wangshan has another role. Childe, please see, the firing mechanism of the Qin crossbow is composed of seven or eight parts of the size, while the crossbows of the six Kanto countries such as the Han crossbow are only half of the parts. Why? Could it be that my Qin State's crossbow manufacturing technology is inferior to theirs? No, in fact, the truth is this: generally speaking, when shooting a crossbow, the crossbowman has to rely on the strength of his fingers to push the tightly strangled bowstring out of the crescent, which requires a lot of effort, and at the moment of firing, the crossbow will definitely have a great shake, so the shooting accuracy is very poor. As for my Qin crossbow, although the shooting mechanism is complicated, as long as the trigger is gently pulled when shooting, the arrow will be shot out through the delicate and flexible shooting mechanism, and the shaking is extremely small, so the power and accuracy of the Qin crossbow should be the first of the seven countries! And this lookout can also automatically pull the trigger back to the firing position when the arrow is fired and rewound. Because it is also connected to an elaborate shooting mechanism! ”
