"Blasting range?" Dong Junwei was puzzled.

"Yes, so to speak, it's the radius of destruction."

"Is it to make it bigger?"

"It's good to make it bigger, but it's also bigger, it's not easy to carry, and for people who don't have enough strength, the throwing distance is also a problem." Chen Dudao.

"We have Lu Shanshan, and when the time comes, we can consider letting her reduce the weight of the grenade, so that it will be easier to throw."

"That's a good idea." Chen Dui bowed: "But we must also grasp the proportion, Lu Shanshan's ability is to reduce the mass of the object, not to weaken the gravitational force, and the decrease in mass means that the kinetic energy and inertia are reduced, if it is too small, I am worried that it will not be able to reach the collision limit and will not be able to detonate." ”

Dong Junwei thought about it for a while, and then understood what Chen Duan meant.

For the thrown object, the lighter the better, once it is light to a certain extent, the lethality is gone.

The same egg-sized, stone and styrofoam, the inertia of the latter may not even be able to overcome air resistance, resulting in simply not far away.

Chen Du said, "But that's not what I meant. ”

"Huh?"

"Increasing the kill radius doesn't have to start with your ability, maybe I can too."

Dong Junwei didn't understand it at first, but quickly reacted: "You want to add something to it?" ”

"Hmm."

Chen Du nodded: "In reality, there are also things like placing iron nails and iron beads in explosives to increase their destructive power, and if the abilities of the two of us are combined, it should not be difficult to achieve this effect." ”

As he spoke, he held the stone in his right hand and gradually melted it into a bowl, while his left hand removed a small piece of stainless steel from the weapon and held it in the palm of his hand.

A full minute or so.

Chen Du spread out the palm of his left hand, and tiny stainless steel beads clanged into the stone bowl in his right hand.

Then, like a dumpling dumpling, he re-enclosed the stone into a ball, but it was slightly larger than before.

"Does this work?"

"Just try it."

After Dong Junwei's "processing" of the stone grenade, there is a very interesting phenomenon, that is, once blasted, the original stone will disappear without a trace, not scattered, but completely disappeared.

This may sound like a violation of the first law of thermodynamics.

Tang Jing also laughed, saying that if Dong Junwei's ability was strong enough to process the entire earth into a giant bomb one day, would she be able to make the whole world disappear together.

Of course, this is just a joke.

In fact, until now, everyone has not even thoroughly figured out the law of Dong Junwei's ability.

Stone is just a broad umbrella term.

In fact, it comes in a variety of forms.

Gelogically speaking, most of the rocks that people see on the surface are sedimentary rocks, but the so-called sedimentary rocks are actually a category named according to the genesis, and under it, there are various classifications, if you have to be specific to the chemical composition, it is more complicated.

Take, for example, the storage room.

The so-called "stones" that the people of Qiming can usually come into contact with come from two sources.

One is cement residue, and the other is all kinds of dust particles, mainly yellow sand.

Portland cement for general construction, the main components are calcium oxide, silicon dioxide, iron oxide, etc.;

Yellow sand, on the other hand, is dominated by silica.

In fact, the cement mortar on the surface of the indoor floor is a mixture of cement and yellow sand.

Therefore, it is almost impossible to find out what the composition ratio of the stones in your hand is, given the current conditions.

And Dong Junwei's ability, which ingredient is effective, or the difference in the effect of various ingredients, may not be able to figure out for a long time.

But this does not prevent everyone from using this simple and inexpensive grenade.

Chen Du made several enhanced grenades in a row, preparing to find a place outside to experiment with the effect.

At this time, everyone has already gotten up one after another.

When I heard that there were new weapons, I wanted to see them.

After breakfast, I found a time when Xiao Huang was not there, and everyone came outside together.

The original crack in the door has been blocked, and a passage has been opened on one side for people and flatbed trucks to enter and exit, and the passage is set up with a heavy iron door, which requires the cooperation of several people to open, and if the internal door bolt is bolted, it is almost impossible to open it with brute force from the outside.

It took a lot of effort for Chen Dui to open this door, but he had to do it.

Otherwise, once he leaves, the people in the room will be trapped inside.

Outside in the open space.

Twilight told everyone to retreat to a safe distance, himself holding an enhanced grenade, and looked around for a usable target.

Soon.

A green worm crawling out of the grass caught his attention.

After reaching a distance of about 10 centimeters, he threw it in the direction of the insect without saying a word.

This insect is not very large, it is thinner than an earthworm, and Chen Du did not hit it unexpectedly, but landed a few centimeters away.

The grenade landed with a thudding sound.

The moment Chen Du made his move, he had already opened a plastic shield that was large enough to cover his entire body.

Through the shield, it can be seen that the effect of this blasting is obviously different from the past.

The original grenade blast had little visual effect, and generally only left a scorched mark at the place of the explosion.

But this time, countless steel balls glowing with silver light splashed in all directions, as if the goddess scattered flowers.

The safety distance is the most important test data.

Otherwise, it will be another version of the M-388 nuclear bazooka, the killing radius is greater than the range, whether it can kill the enemy is another matter, once launched, you will die first.

As it turned out, the shield was still necessary, because two steel balls bounced on it, making a thumping sound.

Although there was not much left, it was clear that the throw distance of 10 cm was too close.

After the first grenade has been blasted.

Chen Duan stepped forward to check on the condition of the green worms.

I saw that several tiny steel balls were embedded in the body of the insect facing this side, and the scalp was numb.

Although these injuries are not going to kill it for the time being, death is only a matter of time.

Next.

After several rounds of experimentation.

In the end, the effective killing radius of this grenade after adding steel balls was set at 15 cm, but it is still possible to be injured at a distance of 20 cm, depending on the quality and quantity of steel balls, as well as the blasting power of the grenade itself.

The smaller the volume, the greater the specific surface area of the object and the greater the air resistance it will experience.

Therefore.

At this time, throwing 20 centimeters, and throwing 20 meters after magnifying 100 times, the former is more difficult.

At this distance, the requirements for arm strength and accuracy are already relatively high, except for Wei Dalei who is very relaxed, even Chen Duan has to hold back his strength to do it.
