A small workshop in Lufu.

The crossbow, also known as the "nest bow" and "cross bow", is a weapon used for archery, it is a bow equipped with arms, mainly composed of crossbow arms, crossbow bows, bowstrings and crossbow machines.

The bow is mounted horizontally at the front of the crossbow arm, and the crossbow machine is mounted at the rear of the crossbow arm.

The crossbow arm is generally made of wood, which is used to support the bow and string, and is supported by the user. The crossbow machine is used to pull the string and fire.

Lv Zhi has first-hand drawings and first-hand samples, and compares them one by one.

There is one thing to say, the crossbow, he still knows something, but as soon as it comes to the details, it will be a black eye.

Fortunately, this thing is not too complicated in terms of structure, at least it is much simpler than a pistol.

Lu Zhi studied for half an hour, and finally had a certain understanding.

"Click~~~" Lu Zhi picked up a crossbow and pretended to shoot arrows, and even dubbed with his mouth, to be honest, this thing is very cool, and it feels super good to play.

After playing for about a stick of incense, Lu Zhi finally put down the crossbow, picked up the longbow on the table on the side, drew the bow, and shot an arrow......

Airplanes~~~

Lu Zhi is not afraid of damaging the bowstring, the empty string is released, the key is that he can't shoot well, and it has no practical meaning if he can't get on the arrow, in case he is accidentally injured again, it will not be good.

The bow and arrow are also very handsome, and Lu Zhi has also tried to practice, but unfortunately it is not that material after all.

"Hey~~~" With a sigh, Lu Zhi put the longbow next to the crossbow and compared the two.

"Well, although the crossbow takes a lot longer to reload than a bow, it has a longer range, more lethality, and a higher hit rate than a bow.

The key is that the requirements for users are also relatively low, and I should be able to master it with practice. Lu Zhi put his hand on the crossbow, and he couldn't be happy.

"The range of the strong crossbow can reach three or four hundred steps, about 600 meters, and the range of the extra-large bed crossbow can even reach six hundred steps, which should be thousands when converted into meters." Lu Zhinian muttered, talking about some of the information he had collected.

"This is the oral statement of Jin Shang, even if there is some bragging, but there is still a certain degree of credibility." Lu Zhi picked up another stack of materials and looked at them one by one, "It can be said that the crossbow is a powerful weapon of long-range destruction. ”

"According to the different methods of opening the strings, it can be divided into arm tension crossbows, stepping tension crossbows and waist tension crossbows, etc., as well as repeating crossbows that can count arrows in salvo or burst fire and bed crossbows equipped with several crossbow bows."

Lu Zhi read the information in a low voice, a little greedy, Da Yue's crossbow making process is relatively backward, far less than the Jin Kingdom, you look at people, a crossbow is played with flowers.

"Relatively speaking, the bow is lightweight, the tensile force requirements are relatively low, it is flexible to use, simple to structure, and the technical content and manufacturing cost are relatively low, which is convenient for mass manufacturing.

To use, the arrow, the bow, aiming, and firing in one go, can have a relatively high shooting frequency, and can be easily used regardless of the horse, and the versatility is strong.

However, the bow's lethality, penetration, and range are relatively limited.

Moreover, when aiming with the bow, you need to maintain your posture and not let go of your hands, which requires good arm strength and training.

Riding on horseback on bumpy horses requires a high level of skill, otherwise it will be difficult to hit.

Compared with the two, the crossbow is relatively heavier, the structure is complex, the technical content and manufacturing cost are relatively high, and the corresponding economic strength and technical strength are required to be manufactured in large quantities.

To use, the tension force when the crossbow is stretched is larger, and the time is longer, of course, the firing frequency will not be high.

Crossbows are not as convenient as bows and arrows, and it is extremely difficult to stretch strings on horseback, but they are better than bows and arrows in terms of lethality, penetration, and range.

In addition, the crossbow no longer needs to be forced, and can calmly concentrate on aiming, so the hit rate is usually higher.

To concentrate your fire on a target, a crossbow is more suitable than a bow. ”

The butt decides the head, and Lu Zhi is the deputy envoy of the Ordnance Bureau, these are all issues that he has to focus on.

"In addition, the use of the crossbow does not require much training, and it is easier to master, so that there is a saying that 'learning is the end of the day'."

This is what Jin Shang said again, damn it, this sentence "learning and becoming successful" is more attractive to Lu Zhi himself, "Even if the talent is not good, you can always master it after three or five days of practice, right?" Three or five days? It's not very long. ”

Before he started practicing, Lu Zhi was overjoyed at first, "And the preloaded crossbow can also be used to deal with emergencies, and the first strike is stronger, which is also a function that the bow does not have." ”

The cold arrow that shot at Lu Yi must be the case, unexpected, and the sneak attack is also a good hand.

Lu Zhi picked up a long collar arrow on the table again, which he also brought back from the Ministry of Works, and it was matched with the sample of the crossbow.

The firing force of the crossbow is greater than that of the bow, and if you continue to use the usual arrowhead, it is easy to cause the arrow to be too large in the arc of the trajectory due to the light body during the flight, and the hit rate is not high, or the arrow shaft is broken when hitting the target.

In order to overcome the above drawbacks, it has become an inevitable choice to increase the length of the collar and increase the weight of the arrow body.

The so-called "collar" is the part of the arrow that is inserted into the shaft at the back of the arrow.

This long-collar arrow is very large, which increases the mass, improves the flight performance, and thus enhances the penetrating power.

The cold arrow in the court hall was even more done, not only did it lengthen the collar, but it was simply made of bronze.

As for why that arrow was so small, it should be a matter of the crossbow.

The guy who is suspected of being a spy of Wu Guo should use a small crossbow, this kind of crossbow is not powerful, the range is not far, and the power is poor.

"Fuck it!" Lu Zhi scolded secretly, "That's why you quenched the poison?" Despicable and shameless, you kid wait for me, wait for me to catch you, see if I don't crush you to ashes. ”

…………

The prison of the criminal department.

With the will of King Yue, Lu Zhi has a wider choice of candidates for the eighteen horsemen.

Since you want to choose someone who can do it, eighteen extremely vicious death row inmates must be very suitable.

"My lord, it has been done according to your request." The cell boss led the way in front, and there was no shortage of sycophants along the way, "It's just that these people are very dangerous, I'm afraid it's ......"

"Well, it doesn't matter." Lu Zhi is a person who cherishes his life, and the key is that he is afraid of pain, how could he rashly put himself in a dangerous situation?

Bang dang dang~~~ This is the sound of iron chains hitting the cell door.

Lu Zhi didn't see him, he heard his voice first, and then took a closer look, and the death row prisoners glared at him angrily one by one, eager to eat his flesh raw, "Okay, good, good, then help me do one more thing." ”

He took out eighteen collars from his arms, "One for each person, put them on for me, and I will come back in a few years, if this matter is done, it will definitely be indispensable to your benefits." ”

The cell boss took the collar, and no matter what these things were, "Okay, don't worry, I'll leave it all to me!" ”

On that day, 18 death row inmates who had been tortured were put on board.

There is always a sentence echoing in their heads, whether they are awake or asleep, "Lu Zhi is the master, you have to listen to the master......"
