The fighter plane passed by at high speed, causing a strong air current in the valley, causing the snow on the trees to fall down.

The deafening roar of the engine resounded throughout the valley. All kinds of beasts were frightened and were running around in confusion, and all kinds of birds were flying around.

Although for the safety of this mission, Song Yongqi had arranged to drive away birds once in advance, but the effect seemed to be insignificant, and many birds still flew back.

If the factor of flying birds is excluded, Yang Luo is 90% sure about this mission. But if the factor of flying birds is added, the confidence drops sharply.

The flying bird is an uncertain factor. No one knows how it will fly. If it collides with it, everything will stop. At Yang Luo's current altitude and speed, there is basically no chance of escape.

Seeing the startled flying birds, Yang Luo was so scared that he had the urge to give up the mission and pull away directly. His heart was in his throat, fearing that some stupid bird that was not afraid of death would fly randomly in front of the nose of the plane.

Compared with the last breakthrough, the danger this time has risen sharply. The height last time was about 300 meters. Even if you really hit a bird, you still have a chance to parachute.

But this time, don’t think about it, just hang it on the wall.

Fortunately, the first thought of a frightened bird is to go into the woods, and no stupid bird directly hit the nose of the plane.

Since it is an extreme mission, we must fly to the limit.

The valley we just entered is relatively long, not very curvy, several thousand meters long, and the valley bottom is also relatively wide, about three to four hundred meters long.

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

Eighty meters.

Seventy meters.

Fifty meters.

Yang Luo didn't dare to continue descending. The air turbulence was too strong, and there would be problems if he climbed down again. At this time, the body of the machine was already undergoing a huge test. The body of the machine was shaking violently, and it was emitting a tooth-breaking crunch.

There was a crunching sound, as if the fighter plane was about to disintegrate in the next second.

He held the control stick tightly with his right hand and stepped on the left and right rudders with both feet, trying his best to control the fighter plane stably and reduce the shaking amplitude.

Since the altitude could no longer be lowered, Yang Luo wanted to make a fuss about speed. He slowly pushed up the throttle valve with his left hand, increased the supply of aviation fuel, and slowly increased the airspeed.

The final airspeed was fixed at a little over 700 kilometers per hour. It wasn't that Yang Luo didn't want to keep pushing it up, but that he didn't dare because it was too fast.

What is the concept of seven hundred kilometers per hour?

After some conversion, we have a very clear understanding: 194.5 meters/second.

In other words, the No. 801 J-7g flies a distance of 194.5 meters per second. In a valley three to four hundred meters wide, if it is operated improperly, it will hit the mountain in less than two seconds.

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

No. 801 J-7g was completely detected by the blind-filling radar of the mountaintop radar station. Its flight parameters were displayed on the radar screen, and information such as altitude and speed were clear at a glance.

All the officers and soldiers in the radar station were dumbfounded and couldn't believe it.

So fast, so low, are you dying?

"Crazy, where did the 31st Division find this lunatic? Do you want your life?" the commander of the 25th Division exclaimed in surprise. This result was so surprising. I thought that at most it would be a slight breakthrough of the original limit, but I never expected it even after thinking about it.

Directly beyond a large margin.

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

They couldn't reach the original record, but now, at 50 meters and 700 kilometers per hour, is it still possible for people to survive?

"It's not him again, is it?" A radar operator suddenly said with his eyes widened.

Another radar operator mused: "You don't mean..."

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

"A month ago, at about 5 o'clock in the morning on September 2, a plane entered the valley and penetrated at low altitude. Looking at the crazy look, it must be the same pilot."

"Last time, the altitude was 300 in the early morning. This time it dropped to 50 during the day. This person is so awesome."

Hearing the words of the radar staff officer, the commander of the 25th Division suddenly felt a sense of hatred and injustice. Why was there no such person in his division, but just a bunch of losers? Looking at the pilot standing next to him, he became more and more displeased, and decided to

Go back and train them hard.

In the air, J-10s were flying over Yang Luo, and the flight status of J-7g No. 801 could be clearly seen. In order to take better pictures, the J-10s kept flying at the same speed as the J-7g No. 801.

The speed of the fighter plane increased, and at this time it also reached an airspeed of a little over 700 kilometers.

Song Yongqi was also shocked by Yang Luo's boldness. He couldn't help but sweat for Yang Luo. He became worried and wanted to turn on the communication device and tell Yang Luo that he didn't have to work so hard and just follow the flight plan.

Although the flight plan Yang Luo submitted to him mentioned altitude and speed, it was only an altitude of 100 meters and a speed of 600 meters, and the current values ​​were far beyond that.

If Yang Luo had proposed a height of fifty meters, no matter what the speed, Song Yongqi would have terminated the mission without hesitation and would not have taken any risks.

You must know that it was Song Yongqi who proposed the task, he was the one who determined the candidates, and he was the one who approved the task. It can be said that all the responsibilities rest on him.

Once something goes wrong, there will definitely be no good results.

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

At the end of the several-thousand-meter-long valley is a mountain nearly three thousand meters high. Yang Luo needs to make his first turn here, and the next test is the real test.

Seizing the right moment, pedaling the rudder to turn right, the 801 J-7g successfully entered the second valley. This valley was more dangerous because it was narrower, only more than 200 meters away, and this valley was extremely winding.

If there are many, you need to keep turning slightly.

The airflow in the valley became stronger, and the shaking of the aircraft increased. It was extremely unstable and difficult to control. It was impossible to fly at a height of fifty meters. It was extremely dangerous. Yang Luo had to pull the lever to climb.

If the plane crashes, it will crash. At worst, it will be replaced by another one, but if you say no, your life will really be gone.

He raised the height to 90 meters, reaching a height that Yang Luo could control. He carefully controlled the 801 J-7g to avoid obstacles in front of him, dashing left and right in the valley.

The 801 J-7g flew precariously in the valley, and every time it was dangerous. It was about to hit it, but it drew an arc and successfully avoided it. It was frightening to watch.

The powerful airflow caused by the plane's passing caused several trees to sway, and the snow on the trees fell down.

Turn left,

Turn right.

Be very energetic, maintain a height of 90 meters, and a speed of 700 kilometers per hour. Repeat these two actions and draw continuous "s" in the valley.

The most dangerous place was a valley with a width of only fifty meters, and the wings of the aircraft almost brushed the tops of the treetops on the mountain.

This is an extremely crazy distance. As long as Yang Luo's right hand holding the control column trembles a little, or his feet tremble slightly and he pedals on the rudder, he will hug the mountain and the machine will be destroyed.

But all of this was successfully overcome by Yang Luo. When Yang Luo, who was cautious along the way, saw the peak of about 1,000 meters in the southwest of An County appearing in front of him, he finally breathed a sigh of relief.

Once you climb over this mountain, the mission will be over.

Flying at an extremely low altitude required extreme concentration and consumed a lot of Yang Luo's energy. At this time, he was exhausted and was breathing heavily on the airborne oxygen.

The danger was basically gone. Yang Luo, feeling relieved, pulled back the control stick, raised the nose of the aircraft and climbed.

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

"Yes, return immediately." Yang Luo responded with a smile.

After 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. Yang Luo usually climbs quickly at a large elevation angle, which is simple and rough. This time it was because he was too tired and didn't want to withstand high overload.

Suddenly, a group of black shadows appeared in Yang Luo's eyes. They were a group of yellow-brown birds flying towards him.
