Gunpowder is a magical thing. The pen "Fun" Pavilion www.biquge.info its production method is simple, but its uses are thousands.

However, when it comes to gunpowder, most of people's first reaction is an explosion.

As early as ancient China, gunpowder was invented by alchemists.

It's just that what makes Wang Hao speechless is that in the system space, for some reason, gunpowder is actually defined as a third-level technology.

It is precisely because of this that the research and development of gunpowder weapons put Wang Hao in a predicament.

Despite having Jiulong Mountain, where fire melons are grown, and a large number of black crystal bombs, Wang Hao still feels that the use of gunpowder will be more extensive.

Last year, Wang Hao used the nitrate produced in the nitrate field to develop the formula of gunpowder.

It's just that gunpowder is very easy to get started, and in China, even a junior high school student knows the materials and approximate proportions of gunpowder.

However, it is very difficult to increase the lethality of gunpowder.

After a whole winter of research, Wang Hao and the others failed to come up with a formula for a high-explosive bomb.

The biggest achievement is the use of gunpowder to make artillery battles such as the Sky Monkey.

If you want to engage in R&D in the wilderness, it is almost impossible.

The knowledge is thin, even Gu Mu can only be helpless when facing gunpowder.

However, with so much effort to build the nitrate field, Wang Hao could not let it be wasted.

Wang Hao finally decided to build a semi-automatic weapon of mass destruction with gunpowder as the center.

This weapon is the ancient Chinese Lianzhu rocket.

As early as the period of the Northern Song Dynasty, rockets appeared in ancient China.

This kind of rocket has four parts: arrowhead, arrow shaft, arrow feather and powder cartridge. The shell of the gunpowder cartridge is made of bamboo or cardboard tube, which is filled with gunpowder, the upper end of the cylinder is closed, the lower end is open, and the small hole on the side of the cylinder leads to the fuse. After ignition, the gunpowder burns in the barrel, producing a large amount of gas, which is ejected backwards at high speed, creating a forward thrust. In fact, this is the prototype of modern rockets.

To put it bluntly, it is a cupola monkey tied to the barrel of an arrow, and then with the help of the momentum of the monkey, the shaft of the arrow is launched to achieve the effect of killing and injuring the enemy.

If, if that's all, then the bow and arrow can also be done, and the accuracy of manual shooting is a hundred times stronger than that of a rocket, then why develop a rocket.

Actually, there are two sides to everything. Although the target of the rocket is a little worse, and the lethality is not as good as that of a bow and arrow, it is a weapon that can attack on a large scale, in a large area, and in a group.

In battle, one rocket, perhaps, is useless, what about two?

Well, two eggs are useless, but what if this number is raised to two hundred, to twenty thousand?

Launching 20,000 rockets at the same time to carry out a covering strike towards an area, this kind of attack without accuracy and completely random, I am afraid that no creature can dodge.

After listening to the carpenter's words, Wang Hao decided to go first to see if the cluster bazooka made by the carpenter was the same as he thought.

Most of the houses in the new village are made of wood.

When the village has a group of mature carpenters, this simple wooden house is much easier to build than a brick house.

However, in the middle of the new village, there are 15 bright brick houses.

Although only a shallow layer of foundation has been dug for these brick houses, they are much more solid than wooden houses.

The carpenter took Wang Hao to a brick house in the middle.

As soon as he entered the door, Wang Hao saw the rocket launcher tied up with hollow bamboo in the middle.

Four hundred hollow bamboos of similar thickness were tied to a wooden cart that could be adjusted at an angle.

The carpenter picked up a rocket from the side and stuffed it into a random quiver.

At the very end, the quiver has a small embedded baffle that is just enough to block the gunpowder accelerator on the rocket, but it allows the lead to be exposed.

Wang Hao looked at it, and the size of the rocket launcher was about the same as his estimate.

When the rocket is placed in the launcher, the position of the arrow is just outside the bamboo barrel, and the position of the tail of the arrow is under the arrow barrel.

Wang Hao counted it, such a rocket launcher has twenty quivers horizontally and twenty quivers vertically, for a total of four hundred quivers.

In other words, if all the rockets are filled inside, the number of rockets it can launch at one time will be 400.

And the time for these 400 rockets to be launched was less than five seconds.

In this way, when the monsters attack the city, in the face of those overwhelming low-level creatures, if Wang Hao has a hundred rocket launchers, he will be able to shoot 40,000 rockets in an instant.

If the firing range of these rockets is narrowed a bit, Wang Hao believes that the places attacked by him will definitely become useless.

"Is this a test?" Wang Hao asked.

"There is no salvo yet, because there are more things needed. However, a small number of shots were tried. The shooting range is only half of that of a bow and arrow, and the lethality is only half of that of a strong bow. However, this kind of power is more than enough to shoot ordinary creatures such as tigers and lions. The carpenter spoke.

"In that case, let's have a salvo test today, and just let those people from other villages see our confidence in Huacheng in the face of monster siege." Wang Hao patted the rocket launcher and said.

The carpenter answered, and went out to call for someone to prepare.

The rocket launcher was pushed into the open space in front of the village, and several clansmen followed with bundles of rockets.

And those people from other villages were also called over by Wang Hao, saying that they wanted to take them to visit a new weapon in Huacheng.

Hwaseong's weapons, these people from other villages have seen many kinds.

There are ballistas, there are Sombra bombs, there are fire melons, and bows and arrows.

Each of these things that brought them was shocking.

Hearing Wang Hao say that there were weapons to show them again, everyone immediately became interested and came out one after another, watching several Huacheng people busy around the rocket.

Four hundred rockets were quickly inserted into the quiver.

However, the time-consuming part of rockets is that if you want to launch them all at once, you have to connect all the rockets' leads together.

The rocket in the middle is still better, and the lead is longer, but the rocket lead in the square is not that long.

In desperation, the clansmen could only bring some more leads and continue them.

Wang Hao patted the carpenter and asked him to remember that the lead needs to be improved, and the lead on both sides needs to be lengthened.

After the entire 400-round rocket was sorted out, Wang Hao estimated the time, and the three of them took almost 20 minutes to sort out the 400-round rocket.

If the speed is increased in the future, this time may be shortened to 20 minutes for one person.

Twenty minutes is too long to decide the outcome of a battle.

In terms of speed, it has to be improved. It is best to reach the speed at which the rocket can be changed in less than a minute.

After thinking about it, Wang Hao asked, "Is your launcher connected to the rocket launcher?" ”

"yes." The carpenter looked at Wang Hao and couldn't understand why he asked this.

"Then you have to find a way to separate the launcher from the launcher, so that we only need to make more launchers, and when we fight, after launching a round of rockets, we will immediately change the launcher. In this case, the speed is much faster than this slow reload. Wang Hao said.
