It was late at night, and the moon hanging high in the sky was shining with silver and stars.

The 301 J-10C, which has just taken off, is climbing to the southwest, preparing to cross the Wuyi Mountains and enter the next Jiangyou province.

The Wuyi Mountains mentioned here do not refer to Wuyi Mountains alone, but to the entire mountain range located at the junction of the northwestern part of Fujian Province and the northeastern part of Jiangyou Province.

Wuyi Mountain Range is connected to Xianxialing in the north, Jiulian Mountain in the south, in the northeast-southwest direction, about 550 kilometers long, about 1000 meters above sea level, the main peak Huanggang Mountain, the altitude is only 2158 meters.

Yang Luo did not need to climb the main peak of the Wuyi Mountains, the place he chose to climb was 850 meters above sea level, so after climbing to 900 meters, Yang Luo was leveled.

In this section of the low-altitude penetration mission, the command center did not give the route, only asked for the result, and everything depended on Yang Luo himself.

When changing ammunition, Yang Luo was chatting with the temporary commander while studying the breakthrough route.

In fact, it is also a general route, after all, after crossing the Wuyi Mountains, you will have to face the threat of ground radar and two fighters, and the route needs to be changed at any time to avoid danger.

"Report to the command center, 301 has been reloaded, ready to enter Jiangyou Province, finished." Yang Luo took a deep breath, looked at the dark mountains in front of him, calmly adjusted the frequency, and contacted the command center.

"301, stay safe and good luck."

In the air command center, the commander looked at the radar screen with a serious face, and the danger factor was too high to penetrate the defense at low altitude at night.

"Lend you good words." Yang Luo said with a smile.

Looking at the mountains that were getting closer and closer, Yang Luo began to be vigilant, according to the theodolite, it was not far from entering Jiangyou Province.

Once you cross the dividing line between the two provinces, you will have to face radar scans from air defense forces and two warplanes that will appear at unknown times and places.

This is a low-altitude penetration with actual combat as the background, Yang Luo can send (shè) two types of training bullets, the other party can do the same, it depends on who points high and low.

Yang Luo knows that he is now in the eyes of the air defense radar unit, and he is waiting for the moment when he crosses the dividing line, perhaps the XL-1C surface-to-air training missile is ready and waiting for him.

Moments before crossing the boundary between the two provinces, Yang Luo turned on the rarely activated active phased array radar and simultaneously scanned the air to the ground.

The greatest danger comes from the ground, but the two fighters are not to be underestimated.

"Drop!"

Having just skimmed over the mountain peaks on the dividing line between the two provinces, the radar siren suddenly sounded without warning, beeping rapidly.

Locked onto by a fire control radar coming from the ground.

"As expected."

Yang Luo said secretly, did not panic, calmly pressed the rudder, adjusted the angle of attack, flew out of a conventional maneuver, avoided the lock from nowhere, and glanced at the radar by the way, but unfortunately there was no information on it, and it was difficult for the airborne radar to find the hidden target from the complex terrain conditions.

Yang Luo shook his head, and the pressure rod dived to quickly reduce the height.

The reason why Yang Luo chose to climb over the Wuyi Mountains from here was to anticipate this result.

In the territory of Jiangyou Province, the mountain is connected by a valley that can quickly dive into the blind spot of the radar.

In the dark night sky, the 301 J-10C, which was lit up with red, green and white light, quickly dived from 900 meters in the air and flew at high speed in the valley.

The roar of huge engines echoes (dàng) in the valley, waking up the many birds that have fallen asleep, chirping and flying around.

"301, watch out for birds, over." The commander reminded through the radio communication system.

"Understood, I'm paying close attention, over." Yang Luo responded.

If you don't pay close attention, the danger of low-altitude penetration at night (xìng) is many times higher than during the day, mainly because you can't fly visually, you can only rely on instruments, and there are birds that fly in the air without regularity, and this time you have to add another condition - unfamiliar territory.

Penetrating at low altitude in unfamiliar areas at night is definitely a technique that can only be mastered by top pilots.

Entering the valley, the mountains on both sides will block the high-frequency electromagnetic waves of the radar, and there is no need to worry about being detected by the radar.

In the dark night, it is impossible to fly too fast in the valley, Yang Luo has been maintained at about 500 kilometers per hour, and still flies in the center of the upper valley, at an altitude of about 400 meters.

If it is lower, it is not that Yang Luo does not dare, but there is no need to increase the danger (xìng).

Yang Luo still remembers the confrontation in September last year, the first time he penetrated the defense at a low altitude in the valley at dawn in the dim light, when he only dared to fly at an altitude of 300 meters at a speed of 350 mph.

But now his skills have improved a lot, the fighters have better (xìng) capabilities, and more importantly, the valley is more spacious and the terrain is not as complicated as it was then.

After more than ten minutes of thrilling flight in the valley, a mountain peak appeared in front of it, with a height of about 1,000 meters, and behind the peak was a plain, about 20 kilometers wide.

Yang Luo had to climb over this peak, over the plains, and into the valley of another mountain range.

These 20-odd roads will be a very dangerous distance.

Perhaps, two fighters that have not been seen are also waiting for them there.

Taking a deep breath of on-board oxygen, Yang Luo's face was solemn, his eyes stared at the black mountain peak in front of him, he pulled the (cāo) longitudinal rod back, pushed the throttle valve with his left hand, increased the angle of attack, and opened the afterburner by the way.

You must increase your speed to climb over the mountain in the shortest amount of time, and cross the empty plains as fast as possible to reduce the probability of being locked.

"Boom!"

As the aviation fuel is injected into the afterburner, the roar of the AL-31FN vector aero engine becomes louder and louder, bursting out with strong thrust, and the high-temperature tail flame of the tail spray (shè) changes from blue to orange, which is particularly dazzling in the dark night sky.

The 301 J-10C roared angrily, like a sharp long sword piercing the night sky, the left and right wings cut the dense air flow in the low air, and the large elevation angle accelerated the climb.

Having just jumped to the height of the peak, once again, as expected, the radar siren beeped rapidly.

Locked on by the fire control radar again.

What made Yang Luo feel a little relieved was that he did not find the shadow of the two fighters, and only needed to deal with the air defense forces.

Rudder, lever.

After performing a maneuver and easily evading the radar's lock, Yang Luo immediately lowered the nose of the plane and dived towards the plain at high speed.

The radar warning went off again.

Yang Luo urgently made another drum maneuver, but he did not evade the lock of the fire control radar, and the rapid alarm sound still did not stop.

Yang Luo simply ignored it, once again turned on the afterburner that had just been turned off, and drove the afterburner to dive, and the speed soared in an instant.

When climbing to the highest point, the speed has been increased to 700 kilometers per hour, and now with the afterburner dive, the altitude is reduced to less than 300 meters in less than two seconds, and the altitude is more than 200 meters.

The chirping of the radar siren stopped instantly.

The time was too short for the radar unit to launch surface-to-air missiles.

PS: There is a problem with the chapter number again, and the last one should be chapter 187.
