Li Shan aimed at some imaginary targets through the crosshair on the muzzle, and pulled the trigger from time to time, he finally found some feeling like playing a gunfight game on the computer, but unfortunately he didn't hear the imaginary "da-da-da" gunshot, it seemed that something was missing.

At this time, I heard a roar in the air, and when I looked up, I saw a helicopter hovering back and forth overhead, the helicopter flew very low, and the red five-star logo on it was very eye-catching.

Li Shan subconsciously raised his rifle and aimed at the helicopter.

"Put down your gun!" The soldier was a little anxious at this time, and hurriedly stopped Li Shan.

"That guy above can see you raise your gun, if he sues you, you and I will be beaten!" Seeing that Li Shan looked a little confused, the soldier explained again.

What are you afraid of without bullets, Li Shan was a little unimpressed, but he still complied with the soldier's request and put down the rifle in his hand. He suddenly remembered the bullets used on his drone, I don't know if it was used in this kind of gun, but unfortunately there were no bullets in the gun, so it was impossible to compare, but it was inconvenient to talk about it with this soldier.

At this time, He Jun's preparations have also been completed, and now it is Li Shan's turn to play, and the next work is relatively simple, he only needs to put the dismantled parts back in the order in which they have been arranged.

At this time, the troops got a few high-power electric fans from somewhere, and they blew vigorously at the plane.

It took half a day of hard work, Li Shan installed all the parts, but this is not the end, whether there is a problem with the installed parts, and it needs to be tested through the test run.

As soon as he said that he wanted to check the test results here, Li Shan was a little big.

The biggest state when he came into contact with the engine was a troubleshoot on the test bench in the factory, and those test workers made a joke with him, and drove the engine to the maximum state, that experience can be said to impress him, although that time was only the maximum state, even this made him feel quite terrifying, and this time it was to drive to the ultimate state of the engine to the maximum afterburner.

Although I have not felt the maximum afterburner state before, I can deduce what the ultimate state of engine operation looks like from the maximum state, and it is terrifying to think about it, but today I am afraid that I have to face this terrifying existence.

The engine started to start, and a roar came into my ears, and the sound grew louder and stronger.

Since this was in the army, the conditions were not as good as in the factory, and only a few limited earmuffs were given to the technicians of the ground support and the airport, while Li Shan only got a lump of cotton.

He pulled a ball of cotton out of it and stuffed it into his ears, but the huge roar of the engine still kept coming into his ears, obviously the cotton was not very effective, so he pulled another ball of cotton and continued to stuff it into his ears, but the noise still stubbornly drilled into his ears, and he subconsciously took a few steps back.

At this time, Li Shan had already put on his shirt, on such a hot day, his shirt that was originally soaked with sweat had already been dried by the hot air, and the strong sunlight passed through his hair and acted on the top of his head, only to feel that his scalp was painful, and the hot air around him seemed to be stagnant, and the whole person was like being in a huge oven.

Despite this, Li Shan would rather stand in the sun than hide in the shade under the fuselage of the plane to feel the noise caused by the test run up close.

At this time, the sound of the engine running is getting louder and louder, although Li Shan is engaged in aero engine assembly, he does not often contact the engine test, and he is not very clear about the state of the engine when it is running, but can only make a rough judgment by the size of the noise.

Li Shan knows that the working state of military aero engines is generally divided into four states, namely, slow train state, cruising state, maximum state, and afterburner state, and the afterburner state is divided into two states: minimum and maximum.

Now the sound of the engine running is getting louder and louder, Li Shan covered his ears with both hands, but he still couldn't stop the sound waves from coming, it felt like a huge wave crashing on the shore, making a deafening roar, and the huge waves crashed into the embankment one by one, stirring up thousands of waves. Like an arrow off the string, like a horse off the reins, like a tiger descending from the mountain, the waves through the mountains and breaking the wall, the momentum is surging down, like a waterfall hanging in the air, banging for thousands of miles.

Now the operation of the engine should have reached the maximum state, Li Shan has also been in contact with this state, just when he was frightened, he felt that the engine began to speed up again, the sound of the engine was like a string of thunder, crisp and piercing, shaking the heavens and the earth, and like thousands of troops and horses galloping, the momentum was like an overwhelming mountain, shocking people's scalps tightened, the earth was shaken, as if the blood of the whole body was coagulated.

was so shocked that Li Shan desperately covered his ears, this should be the maximum afterburner state of the engine, but the ground and technical personnel who looked at the troops seemed to be nothing, and they were busy back and forth in front and back of the plane, and the technician He Jun also stood under the engine, looking inside from time to time.

Everyone was busy nervously, except for the soldier on duty, Li Shan was the only one hiding alone around the plane, which made him feel a little embarrassed.

After being helpless, Li Shan had no choice but to approach the plane, and when it got closer, the sound of engine vibration was even more thrilling.

Li Shan formed the last ball of cotton in his hand, kneaded it with his hands, and then stuffed it all into his ears, almost wrapped both ears tightly, and he had to hold it firmly with both hands because he was afraid of falling off.

At this time, Li Shan had already come to the plane. Seeing him coming, He Jun, who was inspecting under the engine, gave up his position to Li Shan and motioned for him to take a look.

Li Shan leaned into the engine room, only to feel a wave of heat coming, the weather was already high at the moment, and the heat generated by the engine running pushed the temperature up a lot, and in an instant Li Shan sweated like a spring, as if he had been drenched by water, and the clothes and pants on his body were quickly soaked with sweat.

Li Shan carefully inspected the parts he had installed to confirm whether there was oil leakage or air leakage, even if there was a slight problem, if he didn't notice it at this time, if there was a problem once the plane went into the sky, then the matter would be big.

The rolling heat wave hit, roasting Li Shan's face red, and he felt that his exhaled breath was like breathing fire, but this did not affect Li Shan's attention in the slightest.

At this time, his ears could no longer hear any sounds from the outside world, but he could really feel that his heart was beating wildly, and there were signs that it was getting faster and faster.

Li Shan wiped his face with his hand, but found that there was no sweat on his face, which was a little strange at first, but after thinking about it, he understood the reason, which was due to the fact that his face had reached into the engine compartment, and the heat wave inside had dried the sweat on his face.

After observing for a moment and finding no problems, the technicians of the units did not find any problems, they nodded at the same time, and then gave a thumbs up to the ground crew operating in the wheelhouse, who nodded in understanding, and then the engine began to gradually reduce its speed and finally stopped.

The test run is finally over!

The first thing Li Shan did when he returned to the guest house was to hurry up and take a bath in the bathroom, and the troops also specially prepared some light salt water for them to replenish, the water consumed by the body today is too much, and if it is not replenished in time, it may suffer from heat stroke.

This business trip was successfully completed, and then Li Shan was much more relaxed, and he began to wonder whether to go out and walk around. Shanghai is such a famous international metropolis, if you don't take this opportunity to take a stroll, it will be a loss.

In the end, it is an international metropolis, and the atmosphere of modernization is dizzying, and Li Shan can't help but be amazed. In the past, it used to be a paradise for adventurers, with many famous characters and many major events, Li Shan didn't know much about these, and the only person he knew was "Xu Wenqiang".

When he went back, Li Shan planned to take the ordinary train, because the sleeper of the ordinary train only needs to sleep for one night, and there is no need to delay anything, while the high-speed rail needs to sit for 6 hours, and the fare is much more expensive, but because he can't buy a sleeper ticket, he finally has to choose to take the high-speed rail.

The high-speed train to Chang'an departs at 11:25 a.m.

Xu Youjian sighed and said, "Alas, this is not the best time to start. ”

Li Shan, who was next to him, couldn't help but be shocked when he heard this, could it be that this Xu Youjian had some magical powers in terms of unpredictable prophets? Although the thing of time seems to be clear, it always has a certain mysterious flavor in the psychological world of human beings. You know, after all, people now live in an unknown world.

Li Shan asked: "Isn't it good to start at this time? Do you have anything to say at the time of departure of the high-speed train?"

When Xu Youjian said this to Li Shan, Li Shan and other passengers were gathering at the high-speed rail station waiting to get on the high-speed rail.

Passengers are always in a sensitive period when they are away from home, especially for a high-speed object like taking a high-speed rail.

Someone said such things before getting on the high-speed rail, which inevitably makes people feel uneasy, and Li Shan's personal feelings may be a little more serious. Because when Li Shan passed through the security check, according to the requirements of the security personnel, his hands were horizontal, and then the security personnel swept his whole body with an instrument, signaling that he was okay.

Li Shan thought it would be fine.

Unexpectedly, I was suddenly stopped by the security personnel.

"You have liquid in your bag, open it and take a look. ”

"Canned soda, too expensive on the train, bring four. ”

She picked one out of them and said, "Open it and take a sip." ”

So, Li Shan pulled away with a bang, it was all foam, and Li Shan quickly raised his neck and took a sip. But not a small bottle to the ground, the soda fell to the ground and made a "bang" sound, the sound was quite loud, all the people around were startled, and they all cast their eyes over, and several security personnel next to them were very nervous, and hurriedly ran over to see what was going on, after all, in a crowded place like the station, there can be no chaos.
