The two stood at the top of a sand dune a kilometer away, with Cheng Chao holding an AWP sniper rifle in his hand, aiming at a dead tree trunk a kilometer away.

"It's a southeast full-speed wind now, with a wind force of 3, a wind speed of 6.5 meters per second, and a minute angle of 7."

Chen Chen mentioned on the side, "After the shooting, don't look at the result first, immediately turn your back and hide behind the sand dune, understand?" ”

"Okay."

Although he didn't understand what Chen Chen meant, Cheng Chao nodded without the slightest opinion.

Chen Chen put on a pair of sunglasses, only showing one head on the top of the sand dune, ready to escape, "Okay, you can shoot!" ”

Chen Chen's performance made Cheng Chao a little panicked, he simply knelt on the top of the sand dune and aimed at the pendant thousands of kilometers away.

Bang!

With the sound of a gunshot, Cheng Chao didn't look at it, immediately turned around and jumped off the dune, followed Chen Chen's movements and lay down and protected his head.

Then, the two of them waited for more than ten seconds with wide eyes.

Emmmmm……

Nothing happened.

Cheng Chao smiled a little embarrassedly, and then returned to the sand dunes again and started a new round of shooting.

Bang!

Another gunshot rang out.

In order to prevent his eyes from flashing, Cheng Chao first turned his head sideways, glanced at the distance with his peripheral vision, and saw that he still didn't shoot, so he continued the third round of shooting......

Bang!

Bang!

Bang!

……

In this way, it lasted for five minutes, and Cheng Chao shot out three magazines alone, and just when he was a little numb, suddenly a white light flashed in front of him.

Suddenly, Cheng Chao understood something, he turned his head without thinking about it, and immediately jumped off the sand dune!

And Chen Chen, who was behind the sand dunes, only felt a flash in front of him, and the sky suddenly became brighter, and then three seconds later, a deafening sound struck!

Rumble!

With the deafening sound, Chen Chen only felt a shock wave that was about to run out, and the huge impact force lifted the sand on the top of the sand dune!

That's the shock wave formed after the explosion of a powerful explosive!

Suddenly, the two of them were splashed with yellow sand and were almost buried in it.

This shock wave came and went quickly, and after a few seconds, Chen Chen lifted his head from the sand, took off his glasses and shook his head vigorously, and then poured his ears with his mouth open.

The loud noise made both of them have some tinnitus.

Not only that, when Chen Chen looked into the sky, he even found that a circle of regular circular patterns appeared above his head, and the wisps of clouds gathered in the sky to circle the city, and the center was empty and extremely eye-catching.

This power ......

Chen Chen suddenly felt bad, this thing should not be used as an energy store, but as a bomb, and he hung this bomb around his neck for half a year.

Turning over the sand dunes again, Chen Chen saw that the dead tree where the "Galaxy Pendant" was hung before was long gone, not only was the tree gone, but the ground was also gone.

Only a huge crater with a depth of tens of meters and a radius of 100 meters appeared above the surface.

"Is it only about a hundred meters?"

Seeing this scene, Chen Chen couldn't help frowning.

The extent of the crater was only one-fifth of what was expected, so a single sniper bullet only allowed the 'Galaxy Pendant' to excite about 4-5 tons of TNT.

That's one-fifth of the internal energy.

The AWP uses a 12.7×99mm rifle bullet with a known warhead mass of 46.01 grams, an initial velocity of 850 m/s, and a terminal velocity of 0, while the duration of the projectile hit on the 'galaxy' is about 0,01 seconds, according to the momentum theorem, (N-mg) t=0-(-mv), N=mg+mv/t.

In other words, when the bullet hits the "galaxy pendant", the force acting on the galaxy pendant is about 4000N, and if you divide it by the contact area, the pressure can be easily calculated.

And it was these forces and pressures that brought out the power of the four tons of TNT explosives inside the galaxy pendant.

Well, it's intuitive.

Thinking of this, Chen Chen walked towards the big pit, and finally found the unscathed galaxy pendant in the big pit.

Sure enough, even if the energy is stimulated, it can remain unscathed, although I don't know how the aliens in the movie stimulate the internal energy, but it is clear that impact firing is also a way of excitation.

Thinking of this, Chen Chen already understood what he was going to do next.

As long as you find someone to make an electrical device that can charge the galaxy pendant, you can charge it 24 hours a day, even if you have something to leave with the USB flash drive in the future, you can also use the galaxy pendant instead of the USB flash drive to absorb the power.

As for absorbing the power and wanting to excite it, it's even simpler.

Chen Chen only needs to refer to the car engine, first install and fix the galaxy pendant in the combustion chamber, and then wait until the machine starts, the piston will automatically hit the pendant.

With each impact, energy is excited, which pushes the piston back, and the connecting rod of the piston gives the force of the next impact again due to inertia......

Then loop indefinitely.

The only difference between this engine and a car engine is that it replaces fuel excitation by the piston striking the pendant to excite energy, and it is just free from the fuel supply.

Moreover, according to the adjustment of the force of the piston hitting the pendant, you can also control the amount of energy excited by the pendant.

Not only that, Chen Chen also thought of another use of the galaxy pendant.

If only a small amount of energy is kept in the pendant and it is mounted on the initiating device, doesn't it mean that only a small piece of explosive is needed to detonate all the energy in it?

This is undoubtedly a super-powerful bomb, just like just now, with only 4000N, it can reach ten times the power of the Tomahawk missile, which is simply a necessary prop for killing people and traveling at home.

The most important thing is that this prop weighs only 20 grams, and you can take out many of them for backup......

Thinking of this, Chen Chen quickly returned to the research center and began to draw the design of the engine.

And in order to be able to excite as much energy as possible at one time, Chen Chen designed the engine into a multi-cylinder form, each cylinder has a diameter of two meters, and replaced the fuel chamber with an impact chamber, and at the same time canceled the air intake and fuel injection port, and even the spark plug was completely unnecessary.

After drawing the design, Chen Chen called Qian Wenhuan and asked him to contact the German side to see which engine manufacturer could manufacture the engine he designed.

As for the leakage, there is no need to worry about it, as long as Chen Chen declares that it is a handicraft and a hobby, after all, in the eyes of those people, this kind of engine is simply indifferent, and it is impossible to use it at all.

They didn't know about the existence of galaxy pendants, and they wouldn't have imagined that there was a substance in the world that only needed to be impacted to excite energy, and the key was that this substance would not be damaged as the energy was excited.
