The warplanes passed by at high speed, bringing a strong gust of air in the valley, causing the snow to fall from the disturbed trees.

The deafening roar of engines resounded through the valley, and all kinds of wild beasts were frightened and scurried around, and all kinds of birds were flying around.

Although for the safety of this mission, Song Yongqi had arranged to drive birds once in advance, but the effect did not seem to be large, and there were still many birds flying again.

If the factor of flying birds is excluded, Yang Luo has ninety percent certainty about this mission, and if the factor of flying birds is added, the certainty will drop sharply.

The bird is an uncertain factor, no one knows how it will fly, and if it hits, everything will be over. With Yang Luo's current altitude and speed, there is basically no chance of escape.

Seeing the startled bird, Yang Luo was so scared that he was going to die, and he had the urge to give up the task and pull up the detachment directly, and his heart was in his throat, for fear that there would be a stupid bird that was not afraid of death flying to the front of the nose.

Compared with the last breakthrough, the danger of this time has risen sharply, and the height of the last time was about 300 meters, even if you really hit the bird, you will have the opportunity to skydive.

And this time, don't think about it, just hang it on the wall.

Fortunately, the bird's first thought was to burrow into the woods, and none of the stupid birds hit the nose directly.

Since it's an extreme mission, you have to fly to the limit.

The valley I just entered was relatively long, not very curved, several kilometers long, and the valley floor was relatively wide, about three or four hundred meters.

Although there was air turbulence in the valley, which affected the flight attitude, Yang Luo was still slowly lowering his altitude, slowly descending from a hundred meters.

Eighty meters.

Seventy meters.

Fifty meters.

Yang Luo didn't dare to continue to descend, the air turbulence was too strong, and the problem of climbing out of the descent was too strong, and the body at this time was already undergoing a huge test, and in the violent shaking of the fuselage, it was making a creaking sound that made people's teeth ache, as if in the next second, the fighter was about to disintegrate and fall apart.

Holding the joystick tightly with his right hand and pedaling on the left and right rudders, he tried his best to control the stability of the fighter and reduce the shaking amplitude.

Since he couldn't lower the altitude anymore, Yang Luo wanted to make a fuss about speed. The left hand slowly pushes up the throttle valve to increase the supply of jet fuel, and slowly increases the airspeed.

In the end, the airspeed was fixed at a little more than 700 kilometers per hour, not that Yang Luo didn't want to continue to raise it, but he didn't dare, it was too fast.

700 km/h, what is the concept?

Converting to a very clear understanding, 194.5 m/s.

That is to say, the 801 J-7G flies a distance of 194.5 meters per second, and in a valley three or four hundred meters wide, if one is not operated properly, it will crash into a mountain in less than two seconds.

A normal person's breathing rate is three seconds at a time, which shows how short the time is two seconds.

The No. 801 J-7G was completely detected by the blind radar of the mountaintop radar station, and its flight parameters were displayed on the radar screen, and the altitude, speed and other information were clear at a glance.

All the officers and soldiers in the radar station were dumbfounded and could not believe it.

So fast, so low, don't you want to die?

"Crazy, where did the 31st division find the madman? Don't you want to die? The commander of the 25th Division exclaimed, this result was too surprising, I thought that at most it would be a slight breakthrough of the original limit, but I didn't expect to directly exceed a big cut.

After being shocked by the pilots brought over by the commander of the 25th Division, their faces were as pale as earth, because they suddenly thought that this might also become a benchmark for their future training.

They couldn't reach the original record, and now, 50 meters, 700 kilometers per hour, still can't let people live?

"It can't be him again, right?" One of the radar crews' eyes widened and said suddenly.

Another radarman thoughtfully: "You don't mean ......"

"What are you talking about? Do you know who this person is? The commander of the 25th Division asked.

"A month ago, at about five o'clock in the morning on September 2, a plane entered the valley at a low altitude to break through, looking crazy, it should be the same pilot."

"Last time, the height was three hundred in the early morning, and this time it dropped directly to fifty during the day, this person is too powerful."

Hearing the words of the radar staff officer, the commander of the 25th Division suddenly had a feeling of hatred for heaven and injustice, why there was no such character in his division, but a group of rice buckets, looking at the pilots standing next to him, he became more and more unpleasant, and decided to go back and train them well.

In the air, the J-10S flew with Yang Luo, and the flight status of the 801 J-7G could be clearly seen, in order to shoot better, it has maintained the same flight speed as the 801 J-7G, and increased with the increase in the speed of the No. 801 fighter, and at this time it also reached an airspeed of a little more than 700 kilometers.

Song Yongqi was also shocked by Yang Luo's boldness, and couldn't help but sweat for Yang Luo, worried, and wanted to turn on the communication device and tell Yang Luo that he didn't have to fight so hard, as long as he followed the flight plan.

Although Yang Luo submitted the flight plan to him said altitude and speed, it was only a hundred meters of altitude and a speed of six hundred, and the current value has far exceeded it.

If Yang Luo proposed a height of fifty meters at that time, no matter what the speed was, Song Yongqi would not hesitate to terminate the mission and would not take risks.

You must know that it was Song Yongqi who proposed the task, he was the one who determined the candidate, and he was the one who approved the task, so it can be said that all the responsibility is on him.

Once something happens, there will be absolutely no good fruit to eat.

However, now, Song Yongqi didn't dare to speak out, for fear of disturbing Yang Luo's operation, even if he wanted to terminate the task, he couldn't do it now.

At the end of the valley, which is several kilometers long, is a mountain nearly three thousand meters high, where Yang Luo needs to make the first turn, and then the test is the real test.

Seize the opportunity, turn right at the rudder, and the 801 J-7G triumphantly entered the second valley, which is more dangerous because it is narrower, only more than 200 meters, and this valley has a lot of twists and turns, and it needs to be constantly turning slightly.

The airflow in the valley was stronger, the shaking of the body increased, extremely unstable, some difficult to control, and the height of fifty meters could not fly at all, which was extremely dangerous, and Yang Luo had to pull the rod to climb the height.

The plane fell and fell, and it was a big deal to change it, but Xiao Ming said that it was really gone.

Pulling up to a height of ninety meters, to the height that Yang Luo could control, he carefully controlled the 801 J-7G to dodge the obstacles ahead, and rushed left and right in the valley.

The 801 J-7G staggered and flew in the valley, every time it was dangerous, and it was about to collide, but it drew an arc and successfully avoided it, which made people frightened.

The strong air currents created by the planes swept through the trees, and the snow fell from the trees.

Left

Turn right.

Cheer up the spirit, maintain a height of 90 meters, a speed of 700 kilometers per hour, and keep repeating these two movements, drawing a continuous "S" in the valley.

The most dangerous place was a valley only fifty meters wide, with wings grazing almost against the top of the treetops on the mountain.

This is an extremely crazy distance, as long as Yang Luo's right hand holding the joystick trembles slightly, or his feet tremble a little and kick the rudder, then he will have a hug with the mountain, and the plane will be destroyed.

But all of this was successfully broken through by Yang Luo, and when Yang Luo, who was cautious all the way, saw the mountain peak about a kilometer in the southwest of Anxian County appear in front of him, he finally breathed a sigh of relief.

As soon as you climb over this high mountain, the mission will be over.

Flying all the way at a very low altitude required extreme concentration, which consumed a lot of Yang Luo's energy, and he was already exhausted at this time, and he was breathing in a big gulp of oxygen on board.

The danger is basically gone, and Yang Luo, who suddenly felt relaxed, pulled the lever back and lifted the nose of the plane to climb.

"801, congratulations on your successful completion of the mission, now you are returning, the division has prepared a celebration banquet for you." Seeing that the 801 J-7G was climbing, Song Yongqi, who had been worried, finally relaxed and said.

"Yes, I'll be back soon." Yang Luo responded with a smile.

Crossing the mountain, Yang Luo controlled the 801 J-7G to climb smoothly and slowly increase the altitude.

This is not Yang Luo's usual style, generally Yang Luo's climb is a rapid climb with a large elevation angle, simple and rough. This time I was too tired to bear the high overload.

Suddenly, a group of black shadows appeared in Yang Luo's eyes, it was a group of yellow-brown birds, flying head-on in his direction.

"Nima, I won't carry it like this." Yang Luo burst into a foul mouth, and even turned green.
