Primitives are stunned

Chapter 511

The date for the start of the Great Migration has been set.

What made Wang Hao happy was that the carpenter finally developed the large rocket ten days before the date of the Great Migration was set.

The shafts of the large rockets are made of black ironwood.The arrows are still metal arrows, mainly because the metal arrows are sharper and can easily penetrate the enemy's defense.

This kind of large rocket has been tested to be three meters long and weighs fifteen kilograms. The range of a flat shot will exceed 500 meters, but if it is fired directly into the sky, the shooting distance cannot be counted.However, it is conservatively estimated that within 500 meters, it can penetrate the defenses of advanced creatures.

This enlarged rocket was independently designed by the carpenter.

In the beginning, if the gunpowder was filled too much, the bamboo tube filled with gunpowder would explode.

But if there is too little gunpowder and the shaft of the arrow is too heavy, it can only fly a dozen or twenty meters away with the shaft.

Later, after determining the maximum dose of gunpowder, the carpenter thought of a way, that is, to tie three gunpowder tubes for propulsion on the shaft of the arrow in the form of a tripod.

And the three gunpowders, when ignited, will generate thrust at the same time.

The results of the experiment are gratifying. The thrust produced by the three gunpowder tubes is not the result of one plus one plus one equals three.

Its power is multiplied and multiplied upwards.

In that test launch, the big rocket flew 500 meters at a time.

After seeing this method work, the carpenter's mind was opened.

What can't be done with one gunpowder tube, I can use three gunpowder tubes.

So the goal that three gunpowder tubes cannot achieve, does it mean that I can accomplish it with six or even nine gunpowder tubes?

Later, the carpenter tried to tie six or even nine gunpowder tubes to the shaft of the arrow.

However, after the number of gunpowder tubes increases, its weight and volume also increase.Naturally, the wind resistance it suffers also doubles.

In the next test firing, the shooting distance of six or nine gunpowder tubes is not as good as that of three gunpowder tubes.

The carpenter who was at a loss had the result of shooting several times like this. Wang Hao, who learned the news later, made a point based on the experience of rockets flying to outer space on the earth that ignited many times. In this case, why not ignite the rocket? The number of times is divided into two or three times.

There are three rows of gunpowder tubes tied to the arrow shaft.

It was the bottom three gunpowder tubes that ignited first.

After the gunpowder in these three tubes is burned out, the fuse will be ignited, and then fall off by itself, reducing weight.

At this time, the three gunpowder tubes tied in the middle of the rocket will be ignited to continue to provide power for the rocket to move forward.

By analogy, after the three middle gunpowder tubes are burned out, the top three gunpowder tubes will be ignited.

After listening to Wang Hao's suggestion, the carpenter was like enlightened. After more than a week of testing, he finally made a rocket that can fly thousands of meters.

And after testing, the carpenter found that when the gunpowder tubes on the rocket were nine three-layer, the flying distance was the farthest.

If there are six, the rocket is not powerful enough, so it can only fly a thousand meters flat.

And if the number of gunpowder tubes exceeds nine and reaches twelve, the weight of the rocket will be too heavy, and the final shooting distance will be less than that of nine rockets.

Now that the large-scale rocket has been successfully developed, the next step is to mass-produce it and put it into use.

A large rocket car, because of its size, cannot launch four hundred rockets at a time like a small rocket car.It was tentatively set to fire forty rockets.

Before the start of the Great Migration, ten large rocket vehicles, plus [-] rockets, were driven out by carpenters.

This is also the reason why the carpenters in Hwaseong were freed up because the wooden sheds in more than 60 villages were completed.

Otherwise, the [-] large rockets would not be able to be manufactured in a hurry if the two sides started working.

This great migration is of great importance. Except for the construction of Huacheng, other things are not as important as it.

As the most powerful combat force in Hwaseong, Gu Mu handed over all the government affairs in his hands, and together with Wang Hao, accompanied by the first batch of black armor troops who delivered food, went to the vicinity of Snake Cave to meet the Great Western Wilderness on the agreed day The tribes that migrated over there.

Six volts midsummer, scorching sun.The sun in the sky is extremely poisonous.In the air, the breath is full of heat waves.

On the back of the giant clawed dragon, there are two wooden frames like scales.On the wooden shelf, there are a lot of pancakes.

Fortunately, the giant clawed dragon in Hwaseong is a giant clawed dragon that evolved from eating super thatch.

Ordinary giant clawed dragons, carrying such a large pile of things in such hot weather, might not even be able to walk.

In order to reduce the burden on the giant clawed dragon, the Heijia army walked on foot, and those who trot followed the giant clawed dragon.

Some Heijia soldiers even carried drinking water on their backs in order to reduce the burden on the giant clawed dragon.

Biological carapace has a certain ability of sun protection and heat insulation.However, black has a strong heat absorption capacity.

The black armor on the black armor army really made them love and hate at the moment.

When they were walking under the scorching sun without any shelter.

The black armor on his body was like a red-hot iron plate, which was unbearably hot.

However, if passing through a mountain depression or a small forest, under the shade, the temperature of the black armor can drop by more than ten degrees in an instant when a small wind blows.

Under such a hot and cold environment, fortunately, the black armor soldiers whose physique has been strengthened to an inhuman state, if replaced by ordinary people, they will definitely get sick.

Before leaving, Linglong probably sensed that Wang Hao was going to leave for a while.

This time it will follow Wang Hao no matter what.

However, now Linglong has grown to the thickness of a bucket, more than ten meters long.

With such a huge body, Wang Hao will no longer be able to take it on long trips as he did at the beginning.

Snakes prefer shade and shade, if Linglong can't hold on halfway and is unwilling to move forward, it will be troublesome.

I don't know if it's because Linglong is too young, but Linglong hasn't yet evolved its own language system.

The four Gulus struggled to convey Wang Hao's meaning to him.

However, this time Linglong is determined to go out with Wang Hao.

In desperation, Wang Hao could only take Linglong with him this time.

Although her size has grown, Linglong's ability to change color has not disappeared.

After being exposed to the sun for a period of time, Lingling cleverly turned her body transparent.Even its bones and flesh and blood have turned transparent.

Then, sunlight can only penetrate its body, and cannot keep heat on it.

Although Linglong's growth rate is astonishing, this does not change its characteristics as a cold-blooded animal.

After the body became transparent, the temperature on its body was more than ten degrees lower than that of the other side.

Mao Qiu naturally discovered this at the first time, and lazily lay on Linglong's body, using Linglong's body temperature to cool down.

　PS: First of all, I wish everyone a happy Friday.

　　Then, Qianqian brazenly asked everyone for a wave of assists.

　　Due to the high pressure of life, Qianqian opened a new book with a new vest.The title of the book is {Almighty Star}, and the author's name is {Cai Gao Wu Dou}.

　　I ask everyone to collect a wave, and vote for a few recommendation votes by the way.

　　Qianqian has never asked everyone for a recommendation ticket for this book. This time, I will ask for a ticket for the new book. As long as the new book period is over, I will not ask for anything. Thank you everyone.
