The two of them stood at the top of a sand dune a kilometer away. Cheng Cao held an AWP sniper rifle in his hand and aimed at a withered tree trunk a kilometer away.
"It's a full-speed southeast wind now, level 3, 6.5 meters per second, and a minute angle of 7."
Chen Chen advised from the side, "After you shoot, don't look at the result first. Immediately turn around and hide behind the sand dune, understand?"
"Okay."
Although Cheng Cao did not understand what Chen Chen meant, he still nodded without the slightest objection.
Chen Chen put on a pair of sunglasses, only showing his head at the top of the sand dune, ready to escape. "Okay, you can shoot now!"
Chen Chen's behavior made Cheng Cao a little flustered. He simply half-knelt on the top of the sand dune and aimed at the pendant a kilometer away.
"Bang!"
Following the gunshot, Cheng Cao immediately turned around and jumped off the sand dune without looking. He mimicked Chen Chen's action and lay down to protect his head.
After that, the two of them stared at each other for more than ten seconds.
Emmmmm...
Nothing happened.
Cheng Cao smiled a little sheepishly, then returned to the sand dune again and began another round of shooting.
"Bang!"
Another gunshot rang out.
To prevent his eyes from blinking, Cheng Cao first turned his head and glanced into the distance with his peripheral vision. After seeing that he still missed, he continued the third round of shooting...
"Bang!"
"Bang!"
"Bang!"
...
This went on for five minutes. Cheng Cao had used up three magazines of bullets. Just when he was feeling a little numb, suddenly a white light flashed in front of him.
Cheng Cao suddenly understood something. He turned his head without thinking and immediately jumped off the sand dune!
Behind the sand dune, Chen Chen only saw a flash before his eyes. The sky suddenly became bright and then after three seconds, there was a deafening sound!
"Boom!"
Following the deafening sound, Chen Chen only felt a shockwave that was about to run out. The huge impact sent the sand at the top of the sand dune flying!
That was the shockwave formed after a powerful explosive explosion!
Suddenly, the two of them were splashed with yellow sand and were almost buried in it.
This shockwave came and went quickly. A few seconds later, Chen Chen raised his head from the sand, took off his glasses, shook his head hard, then opened his mouth and poured some air into his ears.
The deafening sound made both of their ears ring.
Not only that, but when Chen Chen looked at the sky, he even noticed that there was a regular circular pattern above his head. Wisps of clouds gathered in the sky and circled around the city. The center was empty, which was extremely eye-catching.
This power …
Chen Chen suddenly had a bad feeling. This thing should not be used as an energy storage device but as a bomb. He had been wearing this bomb around his neck for half a year.
After climbing over the sand dune again, Chen Chen saw that the dead tree where the "Galaxy pendant" was hung previously was long gone. Not only was the tree gone, but the land was also gone.
All that was left was a huge pit that was dozens of meters deep and a radius of 100 meters on the ground.
"Only about 100 meters?"
Seeing this scene, Chen Chen could not help frowning.
The depth of the crater was only one-fifth of the expected size. In other words, one sniper bullet only caused the galaxy pendant to release about four to five tons of TNT energy.
That was one-fifth of the internal energy.
The AWP used a 12.7 × 99mm rifle bullet. It was known that the mass of the bullet was 46.01 grams, the initial speed was 850 meters per second, and the final speed was 0. The time when the bullet hit the "Galaxy" was about 0,01 seconds. According to the momentum theorem, (N-mg) t = 0- (-mv), N = mg + mv/t.
In other words, when the bullet hit the "Galaxy pendant", the force acting on the galaxy pendant was about 4000N. If it was divided by the contact area, the pressure could be easily calculated.
It was this force and pressure that triggered the power of the four tons of TNT inside the galaxy pendant.
Well, it was a direct reflection.
Thinking of this, Chen Chen walked toward the big pit and finally found the undamaged galaxy pendant in the big pit.
Sure enough, even if the energy was triggered, it could still maintain a state of unscathed. Although he did not know how the aliens in the movie stimulated the internal energy, it was obvious that the impact was also a method of stimulation.
With this in mind, Chen Chen already knew what he had to do next.
As long as he found someone to make an electrical device that could charge the galaxy pendant, it could be charged 24 hours a day. Even if he had to leave with the USB flash drive in the future, he could use the galaxy pendant to replace the USB flash drive and absorb the power.
As for activating it after absorbing the electricity, that was even easier.
Chen Chen only needed to follow the example of a car engine and first install and fix the galaxy pendant in the combustion chamber. Then, when the machine was started, the piston would automatically hit the pendant.
With each hit, energy would be stimulated. This energy would push the piston back and at the same time, the piston would give the force of the next hit due to inertia...
Then, it would cycle endlessly.
The only difference between this kind of engine and a car engine was that it used the method of the piston hitting the pendant to stimulate energy instead of fuel.
Moreover, according to the force of the piston hitting the pendant, the amount of energy stimulated by the pendant could also be controlled.
Not only that, Chen Chen also thought of another use of the galaxy pendant.
If only a small amount of energy was stored in the pendant and it was installed on the detonator, did it not mean that only a small piece of explosive was needed to detonate all the energy in it?
This was undoubtedly a super powerful bomb. Just like just now, a mere 4000N of force could achieve the power of a Tomahawk missile ten times. It was a necessary tool for killing people and traveling.
The most important thing was that this tool only weighed twenty grams. He could take out many of them for backup...
With this in mind, Chen Chen quickly returned to the research center and began to draw up the engine design.
Moreover, in order to stimulate as much energy as possible at once, Chen Chen designed the engine in a multi-cylinder form. The size of each cylinder reached a diameter of two meters and replaced the fuel chamber with an impact chamber. At the same time, the air intake and fuel injection ports were eliminated. Even the spark plug was no longer needed.
After the design was done, Chen Chen called Qian Wenhuan and asked him to contact the engine manufacturer in Germany to see which engine manufacturer could manufacture the engine he designed.
As for the issue of leakage, there was no need to worry. It was enough as long as Chen Chen claimed to the public that it was a handicraft and a hobby. After all, in the eyes of those people, this kind of engine was simply ridiculous and there was no possibility of it being used at all.
They did not know about the existence of the galaxy pendant, nor would they have thought that there was a substance in the world that could stimulate energy by just hitting it. The key was that this substance would not be damaged by the stimulation of energy.
