My friends never expected that Ye Han, who looked like a bookworm with thick eyebrows and big eyes, would actually pull such a trick!
To his surprise, he was actually fooled and agreed to his application.
Of course, three or four will definitely not work, even if Ye Han's words are ridiculous.
The efficiency of substance preparation is a geometric sequence with a coefficient of 4. If you upgrade it to three levels, the efficiency can be increased by 64 times! Level four is 256 times!
The amount of grenade ammunition is generally about 100 grams. With Octogen, 50 grams is enough, and the power is even stronger, so it is equivalent to one grenade per minute for level three, and only fifteen seconds for level four...
It's no use. You can't give him all the bags without leaving any margin. Everyone should tighten their belts, right?
Grenade may be useful, but in terms of accuracy and convenience, it has to be a gun!
Just gave one.
After all, graphene of more than 30 centimeters is a bit narrow. Why should it be more than 60 centimeters, or 1.2 meters wide, to be more convenient for making clothes?
As a result, none of them were used.
Because the upgrade package has restrictions...
At present, in the first circle, the items seem to only reach +2.
Ye Han calculated all the way to positive infinity, and the result is that the valid interval is {0,1}...
It's really a wave of operations as fierce as a tiger, at first glance...
Ye Han was helpless, but Gao Yiben breathed a sigh of relief.
It's not that I'm worried about the upgrade package being squandered, but because, in this case, the mysterious man can only get +2...
That's great!
Otherwise, wouldn’t it be unreasonable for him to have more than ten or twenty bags?
Ten or twenty bags?
Well, that's no exaggeration at all.
Let’s do the math. Killing 10 people equals 10 bags. Those who were wiped out just now probably had inventory, and they were all searched. Add in the inventory of other dead people. The number of kills is far ahead of the possible rewards. There are no teammates to share the consumption.
…
A dozen or twenty bags are already far less.
The weapons are strengthened to such an extent that the ump is more powerful than a girl, the m416 is more powerful than an m24, a frying pan costs 200+, and the awm thugs can be killed instantly...
It’s scary to think about it!
This is still a linear increase. You must know that +1+2+3... in the game often increases exponentially.
The traffic anchor has thought of this for a long time, and just suppressed it in order to stabilize the morale of the army.
It’s great to not have to face enemies who can blend in with the zombies without leaving a trace and kill them instantly by jumping out!
However, since he can only get +2, how did this guy kill so many people?
Thinking about it...it seems even scarier. What must be done?
"Eh? Why has it turned black? It's a little... cracked?" Su Xingmou's voice suddenly sounded.
When I turned around, I saw that the female star was wrapping graphene around her body.
The team does not have a tailor, but it does not need a tailor.
There were mummies in ancient times, and soldiers wore leggings during wars. Female celebrities who often walked on the catwalk knew how to use pins and paper clips to fix pieces of cloth to their bodies.
Tangled and rolled, one layer and two layers...
There is an attraction between graphene layers, similar to electrostatic adsorption. Once the distance is close enough, it will show up as van der Waals force, which is the attraction between graphene layers, destroying the perfect two-dimensional structure.
If Su Xing's eyes are rolled beyond the number of layers, they will definitely become graphitized, turn black and become brittle.
Even if the layers do not adsorb each other, the surface of graphene still has the ability to adsorb ions and molecules, and different adsorbates will cause changes.
It's like if the tape is exposed, it will continue to be stained with things, become dirty, and gradually lose its stickiness, so it can no longer be called a tape...
The friends all looked at Ye Han, hoping he would give an explanation.
Ye Han was stunned.
It's not that he didn't expect the secret to be revealed so quickly, but... looking at Su Xing's eyes twinkling, he suddenly had an idea!
Yes!
Although it is just a slit, who said that a slit is just a two-dimensional flat atom printer?
It may not be possible to offset the strong interaction force, merge atomic nuclei for fusion, or ignore the electromagnetic repulsion of hydrogen nuclei and carry out the densest packing in three-dimensional Euclidean space.
After all, these are operations that often require temperatures of hundreds of millions or millions of atmospheres, but two-dimensional materials can be bent and folded in half!
Ionic bonds, covalent bonds, metal bonds, hydrogen bonds, salt bonds, halogen bonds, weak van der Waals forces, hydrophobic forces, aromatic ring stacking effects... There are actually many operations at the atomic level of molecules.
Just like graphene, it is difficult to make a single layer. If it is rolled up, wouldn't it be a carbon nanotube?
This is absolutely possible!
It has the highest known melting point and its tensile strength is 276 times that of steel and one order of magnitude higher than carbon fiber. It can be flattened under 1,000 atmospheres of pressure and can quickly return to its original shape like a spring when the pressure is removed.
Collect a bundle, weave it into silk, weave it into a net, and make it into a bulletproof vest. The effect is absolutely amazing, almost as good as graphene.
It's a pity that it takes a lot more effort to use this thing than graphene.
Graphene only needs to be able to cut. This thing needs to be able to spin thread and weave cloth first, and then it can be the tailor's turn...
But when it comes to spring compression, the strongest explosive currently produced in the laboratory, octanitrocubane, is almost a perfect cube. It seems that a two-dimensional printer cannot print it, but it can be flattened first, just like origami, combining various chemical bonds.
If you connect them in a flat state, wait for them to pass through the slit and expand them, wouldn't they become three-dimensional?
Origami structural mechanics and topological kinematics specialize in this...
Tsk, it’s a pity that those are relatively fringe subjects. I’ve only heard of them but haven’t studied them carefully.
When you leave this place, you must find an opportunity to study it!
Ye Han thought about it for a moment, wandering around arxiv, a spark of inspiration.
The friends asked a few questions, but Ye Han didn't answer, so they stopped asking.
"Maybe there is a time limit? It's past time now..."
"If you can't just make things and keep doing it forever, that would be too imba..."
Gao Yiben guessed, taking Ye Han's blankness as the embarrassment of not understanding the skill description.
Ye Han came back to his senses and shrugged, not bothering to explain that there was an upper limit to the slit upgrade. If you couldn't upgrade it, it would be useless no matter how much you waste.
Set your mind and start constructing the planar structure of octanitrocubane.
If this thing can be made, the power of the explosive can be increased by several percent. Moreover, the molecular formula of octanitrocubane is c8(no2)8. It does not require hydrogen. Nitrogen plus oxygen plus carbon dioxide is enough. More materials must be collected.
convenient.
Each selected their main weapon, and the friends started sweeping along the edge of the circle to clear the area.
Koi Su Xingmou chose the counterclockwise direction, and the team moved in an off-road jeep, taking advantage of the advantageous terrain of the border zone to kill corpses efficiently and practice shooting at the same time.
