It took Yang Jing nearly an hour, and he changed three impact drills in a row, to drill more than 20 holes 30 centimeters deep at the bottom of the stone. Yang Jing was almost exhausted to death. Doing such physical work in such a temperature is simply seeking death.
Fortunately, Yang Jing had the skill to repay his parents, so he was able to persevere.
Then Yang Jing took out C4 from the storage space and stuffed them into the holes respectively. He inserted small mine chambers on the outside, gathered all the fuses of the mine chambers together, and finally tied them to a longer fuse.
Yang Jing actually didn't know how to use C4, but even if he hadn't eaten pork, he had at least seen pigs run. In addition, on the flight back to Yanjing, he specifically asked Chris and a few others for advice. So even though he had never operated C4 before, he at least knew how to place and detonate this extremely powerful explosive.
As for the dosage, he had no idea. But Yang Jing knew very well that if he wanted to blow up or blow up this huge rock, he would need less explosives, so he stuffed a lot of C4 into each hole.
The fuse that was released was of course also a safety fuse. This section of the safety fuse takes one minute to burn out, which is enough for Yang Jing to run two hundred meters.
After finishing all these tasks, Yang Jing looked at the thermometer. The temperature was still as high as 45 degrees Celsius, so Yang Jing took out the motorcycle from the space without hesitation, started the engine, and ignited the safety fuse.
After lighting the fuse, Yang Jing got on his motorcycle and quickly rushed to another hilltop more than 300 meters away. With the powerful power of the motorcycle engine, Yang Jing ran to the back of the other hill in less than half a minute. There were two more hills between this position and the big rock, so there was no need to worry about safety.
The main reason for blowing up this huge rock at this time instead of at night is that the temperature is high at this time, and the distance of sound propagation is much shorter than at night when the temperature is low. Although the nearest Ghadames Airport is 20 kilometers away and surrounded by many mountains, Yang Jing is not sure whether the sound waves produced by the explosion of so many C4s can be heard by people at the airport.
Moreover, if it is detonated at night, the light effect will be quite large. Even if no one can hear it, what if someone sees it?
So while the sun is still high in the sky and the temperature is high, why not just detonate it!
Yang Jing got out of the car and sat in the middle of the canyon. He didn't dare go to the foot of the mountain. Who knows if the vibration of the explosion will shake down the rocks on the mountain? What if a rock fell down and he happened to be under that rock...
He took out the earplugs from his pocket and calmly put them into his ears. Only then did Yang Jing focus on the situation over there.
After a minute and a half, Yang Jing suddenly felt a slight vibration under his buttocks, and then a stream of air came along the surface of the canyon. This should be the shock wave generated by the explosion. However, because the distance was 400 meters and there were two mountains in between, the shock wave had no power when it arrived here.
However, the sound that followed made Yang Jing feel a little dizzy even though he was wearing earplugs.
There was no other way. Detonating a large amount of C4 in the canyon would increase the sound produced by the explosion after reverberating through the canyon, causing Yang Jing to be seriously injured. However, this situation was not without its advantages. That was that the sound waves would decay quickly after reverberating through the canyon and would not propagate that far.
Yang Jing waited for a while and made sure that there was no problem over there. Then he rode his motorcycle back there carefully.
Even though more than a minute had passed, the area was still covered in dust. The explosion had almost completely covered the entire canyon with dust. Fortunately, the canyon was more than a hundred meters deep, so the dust did not spread beyond the top of the canyon.
After waiting for several minutes, when the dust gradually settled, Yang Jing saw the stone that was as big as half a house.
The stone was still there, but it was half as small, and the remaining upper half was several meters away from its original location.
In order to blow up this big rock, Yang Jing placed two kilograms of C4. You know, as long as it is placed in the right place, just one kilogram of C4 can easily raze a five-story apartment building to the ground. Two kilograms of C4 is enough to match the size of this rock.
