Chapter 108 Killing Radius
"Explosion range?" Dong Junwei was confused.
"Yes, it can also be said that it is the killing radius."
"Do you want to make it bigger?" "
Making it bigger is good, but the weight will be larger, which is not convenient to carry, and it is not suitable for people who are not strong enough. , throwing distance is also a problem." Chen Mu said.
"We have Lu Shanshan. At that time, we can consider letting her reduce the weight of the grenade, so that it will be easier to throw." "
This is indeed a good idea." Chen Mu nodded: "But we must also grasp the balance. Lu Shanshan's ability is to reduce the size of objects. Mass does not weaken gravity, but a decrease in mass means a decrease in kinetic energy and inertia. If it is too small, I am worried that it will not reach the collision limit and will not detonate." Dong Junwei thought for a moment and understood what Chen Mu meant
. .
For thrown objects, lighter is not always better. Once it reaches a certain level, its lethality is gone.
The inertia of the same eggs, rocks, and Styrofoam may not even overcome air resistance, causing it to not be far away at all.
Chen Mu added: "But that's not what I meant."
"Huh?"
"Increasing the killing radius does not necessarily have to start with your ability. Maybe I can."
Dong Junwei didn't understand it at first, but quickly reacted Come over: "Do you want to add something inside?"
"Yeah."
Chen Mu nodded: "In reality, there are also things like iron nails and iron beads placed in explosives to increase their destructive power, and if the two of us It should not be difficult to achieve this effect with the combination of human abilities."
As he spoke, he held the stone in his right hand and gradually melted it into a bowl shape, while his left hand took off a small piece of stainless steel from the weapon and held it in the palm of his hand inside.
A full minute or so.
Chen Mu opened the palm of his left hand, and tiny stainless steel beads clinked into the stone bowl in his right hand.
Then, like wrapping glutinous rice balls, he re-sealed the stone into a ball, but the volume was slightly larger than before.
"Is this effective?"
"You will know after you try it."
There is a very interesting phenomenon in the stone grenades that have been "processed" by Dong Junwei. That is, once blasted, the original stones will disappear without a trace. Scattered in all directions, but completely disappeared.
This sounds like a violation of the first law of thermodynamics.
Tang Jing once laughed and said that if one day Dong Junwei's ability is strong enough to process the entire earth into a giant bomb, will the whole world disappear together?
Of course, this is just a joke.
In fact, until now, no one has even fully understood the rules of Dong Junwei's ability.
Stone is just a broad term.
In fact, it comes in many forms.
Geologically speaking, most of the rocks people see on the earth's surface are sedimentary rocks. But the so-called sedimentary rocks are actually a category named according to their origin. Under it, there are various classifications. If you have to be specific, Chemical composition, then it’s more complicated.
Take the storage room as an example.
The so-called "stones" that people in Qiming usually come into contact with generally come from two sources.
One is cement residue, and the other is various dust particles, mainly yellow sand.
The main components of Portland cement used in general construction are calcium oxide, silica, ferric oxide, etc.;
while yellow sand is mainly composed of silica.
In fact, the cement mortar on the surface of indoor floors is a mixture of cement and yellow sand.
Therefore, it is almost impossible to figure out the composition and ratio of the stones in your hand under the current conditions.
As for which ingredient Dong Junwei's ability works on, or the differences in the effects of various ingredients, it may not be clear for a long time.
But this does not prevent everyone from using this simple and cheap grenade.
Chen Mu made several enhanced versions of grenades in succession and was going to find a place outside to test the effect.
By this time, everyone was getting up one after another.
I heard there were new weapons and wanted to take a look.
After breakfast, we found a time when Xiao Huang was not around, and everyone came outside together.
The original door gap has been blocked, and a passage has been opened on one side for people and flatbed trucks to enter and exit. A heavy iron door is set up in the passage, which requires the cooperation of several people to open. If the internal door bolt is bolted, It is almost impossible to open it with brute force from the outside.
This door took a lot of effort from Boss Chen Mu, but he had to do it.
Otherwise, once he leaves, the people in the room will be trapped and die.
Outdoor space.
Chen Mu asked everyone to retreat to a safe distance. He held an enhanced version of the grenade and looked around for available targets.
soon.
A caterpillar crawling out of the grass caught his attention.
After he walked to a distance of about 10 centimeters, he threw it in the direction of the insect without saying a word.
The insect was not very big, and was slightly thinner than an earthworm. As expected, Chen Mu missed the target and landed a few centimeters away.
The grenade hit the ground and made a loud explosion.
The moment Chen Mu took action, he had already opened a plastic shield that was enough to cover his entire body.
It can be seen through the shield that the effect of this explosion is obviously different from the past.
The original grenade explosion had almost no visual effect. It usually only left a burnt mark at the place where it exploded.
But this time, countless silvery steel balls flew in all directions, like a goddess scattering flowers.
Safety distance is the most important test data.
Otherwise, it will be another version of the M-388 nuclear rocket launcher. The killing radius is greater than the range. Whether it can kill the enemy is another matter. Once launched, you will die first as a respect.
It turns out that the shield is still necessary, because two steel balls bounced on it and made a banging sound.
Although there is not much remaining power, it is obvious that the throwing distance of 10 centimeters is still too close.
After the first grenade exploded.
Chen Mu stepped forward to check on the caterpillar's condition.
I saw several tiny steel balls embedded in the insect's body facing this side, which made people's scalp numb.
Although these injuries will not kill it for the time being, death is only a matter of time.
Next.
After several rounds of experiments.
In the end, the effective killing radius of this grenade after adding steel balls was set at 15 centimeters, but it is still possible to be injured from a distance of 20 centimeters, depending on the quality and quantity of the steel balls, as well as the explosive 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.
Throwing 20 centimeters at this time is more difficult than throwing 20 meters after magnifying it 100 times.
At this distance, the requirements for arm strength and accuracy are relatively high. Except for Wei Dalei who was very relaxed, even Chen Mu had to hold back his full strength to do it.
