When the bolts from the Eight Bull Crossbows were fired, the place where the stone mountain in the distance was aimed collapsed at a speed visible to the naked eye. The pen %fun %pavilion www.biquge.info and the crossbow arrow disappeared directly.

It wasn't until two seconds later that the sound of crossbow bolts and stone mountains crashing came.

The dull sound of impact penetrated his heart, and even Wang Hao was shocked.

As for the giant frog king, who was originally scheduled to be a live target, he was so frightened that he screamed three times in a row.

Evolution has given it no less intelligence than humans, and it is natural to be able to imagine what the result of this eight-bull crossbow shooting at itself will be.

When the clansmen cleaned up the collapsed gravel where the crossbow arrow was shot, Gu Mu wiped away the nosebleed and told Wang Hao that the force carried on the tip of the arrow reached a terrifying thirty-seven tons.

You must know that even if it is a two-haired bull on the Great Wilderness, the force of the impact is only more than 20 tons.

Think about it, what a terrifying thing it is to concentrate such a huge impact force on one point.

Moreover, Gu Mu also told Wang Hao that this was just an ordinary impact force.

As for the crossbow arrows, the rotational force generated by the special spiral blade arrows in flight has not been taken into account.

Because the speed at which the crossbow bolts rotated was so amazing that even Gu Mu, who had special vision, couldn't see clearly, so he naturally couldn't calculate it.

The rubble from the place where the bolts were fired was quickly cleared, and cracks like spider webs spread all over the mountain.

In the center of the crack, a dark hole with a diameter of a meter wide appeared.

A black-armored soldier lit a torch and went into the cave, dragging in his hand the hemp rope that Wang Hao used to measure the cultivated land. When the hemp rope stopped advancing in the cave, Wang Hao saw that the scale on the hemp rope stopped at a distance of six meters.

Under one blow, the crossbow arrow not only pierced through the hard stone, but also penetrated more than six meters into the stone, which is not an exaggeration to call it the king of cold weapons.

The Black Armor Army came out of the cave and told Wang Hao that the hemp rope touched the end of the crossbow arrow.

As for the front end, it is all stone strips that are cut into twisted flowers by high-speed rotating crossbow arrows and then protruded, and people can't get past them at all.

He tried it inside, and the crossbow bolt was firmly embedded in the stone mountain, and it was basically impossible to take it out by manpower.

When the Black Armor Army said this, everyone was even more surprised, in this way, the tip of the crossbow arrow should be more than nine meters deep into the mountain.

Although the expressions of the several black-armored soldiers who shot the Eight Bull Crossbows could not be seen clearly, judging from their staggering steps, their hearts should be very unsettled.

Due to the special structure of the arrow, the enhanced version of the eight-bull crossbow allows it to rotate at high speed in flight, and the penetrating force generated by it is out of the category of crossbow arrows.

Now, it can no longer be a ballista, but a ballista.

Although the lethality of the eight-bull crossbow is amazing, the recoil is amazing.

Unlike hot weapons, the impact force is the most important attack method for cold weapons such as crossbow arrows. Therefore, although it is very simple to add a smoothbore to the ballista to slow down the recoil, it will definitely reduce the power of the crossbow arrow, so although the material of the eight-bull crossbow has changed and the volume has become larger, the final shape has not changed too much.

The Black Armor Army that transported the Reinforced Eight Ox Crossbow back to the village knew that when one day, they could overcome the recoil and accurately hit the target with the Reinforced Eight Ox Crossbow, that would be when their Black Armor Army declared war on the third-level creatures.

On the tenth day, the 3,000 acres of land in the Grand Canyon were finally completely divided.

Wang Hao lay on the grass with a painful face, blaming himself for being lazy, if he took the time to give two more classes to the good students in the school, and now at least a few people who can help, then he will not be so tired.

Usually lazy, when it comes to the critical time, he is still tired, Wang Hao decided, when he goes back this time, he must teach seriously and never be lazy.

The matter of strengthening the Eight Ox Crossbow was perfectly solved, but there was a problem with the progress of the repeater.

There are countless kinds of crossbow arrows in the system space, whether it is a fully automatic crossbow arrow driven by gas with a number of crossbow arrows exceeding 1,000 yuan, or a crossbow arrow that can be automatically wound back and forth to form a perpetual motion machine, which can be downloaded by the secondary system.

Wang Hao searched for a long time, and finally found several suitable crossbow arrows from the download category of the secondary system, but none of them could really be called repeaters.

The first is the famous Zhuge Repeater.

The inverted magazine and the wrench-type winding bracket allow the second arrow to be fired immediately after shooting one arrow.

Because of the lack of winding, the speed is about three times that of a bow and arrow.

In Wang Hao's opinion, this kind of repeater should be the most worthy of ligature.

There is also a kind of repeater, which can shoot dozens of crossbow arrows at the same time in a swarm, and can instantly attack a large area like a shotgun.

But the disadvantage is that it is wound at once, which varies from a few minutes to more than ten minutes, depending on the number of crossbow arrows.

Finally, there is a multi-stringed repeater, capable of storing up to five crossbow arrows, firing a single bolt with a single pull of the trigger.

Pull the trigger five times, and all five arrows are fired.

However, the disadvantage is that it takes too long to wind.

Because of these various shortcomings, repeaters are only useful under certain circumstances, so the number of repeaters downloaded by Wang Hao is not large.

Of course, for Wang Hao, the most restrictive reason for the development of repeater is because of crossbow arrows.

Compared to bows and arrows, the shafts of repeaters are shorter and smaller.

If this feature is placed on the earth, there is naturally nothing, as long as it can shoot people.

But in the Great Wilderness, because the vitality of wild beasts is generally strong, the size requirements for the arrow shaft are higher.

If the size is not reached, then the only way to increase the lethality is to increase it.

Therefore, a material as light and fluttery as arrow wood is not suitable for arrow shafts.

The three kinds of crossbows downloaded by Wang Hao consumed the same crossbow arrows as the Eight Bull Crossbows, all of which were alloy crossbow arrows downloaded from the system.

The Level 2 system can only craft ten things a day. Even if Wang Hao doesn't do anything for a year, just making crossbow arrows, he can only make 3,650 crossbow arrows a year.

This amount, let alone fighting, will be consumed by even a big training.

It's not that Wang Hao didn't think about making it himself, but the melting point of iron is far greater than that of copper, and when there is no coal mine, no matter how fast the blower is pulled, the temperature cannot be reached.

Therefore, although the repeater appeared, it is not very practical at present.

On the fifteenth day of coming to the Grand Canyon, Wang Hao finally planned to go back.

Rows of thatched huts line the center of the Grand Canyon.

The level at the entrance to the canyon is only one-fifth complete, and it is beginning to take shape.

This time, Wang Hao went back not because the affairs of the Grand Canyon were over, but because the full moon night of stealing knowledge once every three months was coming again. Wang Hao needs to take this opportunity to experiment with some of his conjectures.
