After talking to Xu Haoran about staring at the drone, Xu Ziling went downstairs.

first made a phone call to Yang Ruolan, who was at school today, and told him that he had something to go out for a few days, and then he called Wang Jian, and then he sent himself to the 81st Division.

"How long are you going to go this time?"

Two months ago, Wang Jian and Shen You moved to a newly bought house, which happened to be in a neighborhood with Xu Ziling, and during this time, they commuted to work together a lot of the time.

Brothers are brothers, but he knows that Xu Ziling's identity is different from him now, and seeing that he is going out, he doesn't ask where he is going, but just asks him how long he has been gone.

"It won't take long, a week at most, and you know about the matter at the Technical Exchange Center?"

"Today, I wonder how such a thing could happen in that kind of place."

In fact, Xu Ziling felt that this matter was not simple, at the beginning of the establishment of this unit, the state security department sent a special person to be responsible for the secrecy work, and under such a strict arrangement, there was actually a leak of secrets, which is really a bit incredible.

He always felt that something was wrong with this, but he couldn't think of anything for a while.

If it weren't for the fact that the information wasn't very important to the military factory, and that he didn't have much time to spare, he really wanted to investigate it himself.

"People like spies are always unguardable, you should pay more attention to this matter, and send any progress to my mailbox."

After thinking about it, Xu Ziling still explained that Wang Jian cared about this matter.

"Okay."

Soon arrived at the 81st Division, Wang Jian had something to do, and he didn't delay much, chatted with Lin Jianbin who came out to pick up people from inside, and drove back.

"How many days are you going to come back this time?"

As soon as Wang Jian left, the two walked towards the airport, and Xu Ziling asked Lin Jianbin with a smile.

"When you come back, I will come back."

Lin Jianbin glanced at Xu Ziling.

"Forehead......" Xu Ziling was stunned, "Then I may take a week, you have so long?" ”

"This time it's a mission, what time is not time, the main thing is this thing in your hand, do you still want to finish the matter and come back on a civil aviation plane?"

"Then I'd love to have someone pick me up."

After listening to what Lin Jianbin said, he understood that this thing in his hand was too important and important, so for the sake of confidentiality and security, he simply let this mission be a full pick-up.

When they came to the airport, the two changed their equipment, and when they arrived at the hangar, they saw the J-10 two-seater fighter that had already completed the take-off inspection.

The main flight must still be from Lin Jianbin , so Xu Ziling still sits in the back seat.

The two got on the plane, and the ground crew immediately drove it out of the hangar and onto the runway in a tractor.

After some preparations, the plane soon took off from the runway and flew towards the Sword base.

~~~~~~~~~~~~~~~~~~

A few hours later, the sword base.

Xu Ziling and Lin Jianbin got off the plane, and the ground crew immediately came over to put the fighter into the hangar, and Yang Kaiming, Li Cheng and others immediately ran over to greet the two.

"Binzi, I haven't seen you for months."

"No way, who told you that the door here is hard to enter."

"Ha Lu Ha ......"

Lin Jianbin This joke caused a burst of laughter from everyone, the gate of the sword base is indeed difficult to enter, as long as it is not the initiative of the base, it is really difficult for people who are not from the base to come here.

"Go, go, don't stand here anymore, go inside and talk."

When they arrived at the office area in the base, they asked Yang Kaiming and them to greet Lin Jianbin and Xu Ziling went to see the captain Zhu Gang alone.

Xu Ziling's own identity is special, and there is no estrangement between the general superiors and subordinates when the two meet, and after talking about some family routines, he seriously discussed the matter of this mission before he said goodbye and went out.

Because when he arrived at the base, it was afternoon, and Xu Ziling didn't start doing things that day, and he also had a small gathering with many acquaintances in the base.

The next day, he went into the arsenal alone to modify the high-explosive ground-penetrating bomb.

To modify this missile, there is not much work, just change the relevant programs inside, and load a guidance signal conversion module.

Originally, such a change must be authorized by the missile manufacturer, but he has a lion, so he doesn't need these at all, just crack the system inside, change the relevant control program, and then install the conversion module on it.

However, this missile was not as easy to modify as the PL series, and although it was fast enough, it took a full day to get it right.

Then there was nothing to do, because the drone hadn't been done yet, but he was keeping an eye on the progress there, and seeing that the time was completely in time, he wasn't in a hurry.

Accompanied Lin Jianbin around the base for more than a day, and on the afternoon of the third day after arriving at the sword, he finally received the news that the drone was ready.

Thinking that the drone had not yet been tested for night flight, as soon as he received the news, he immediately asked the military factory to start preparing for the drone, and decided to let the drone fly to the sword at night.

The winter night came very quickly, and before six o'clock in the evening, the operational command hall of the base was brightly lit, and the team leaders headed by Captain Zhu Gang, Yang Kaiming, Li Cheng, Lin Jianbin, Lao Bai, Xiao Niao, and some other people were all present.

This time, there was no satellite synchronization picture, but Xu Ziling used his authority to enter the security system of the military factory in the base, and put all the monitoring pictures around the airport on the big screen in the command hall.

The military factory in the picture is now also brightly lit, as bright as day.

The time will soon be six o'clock, and in the picture of the hangar on the big screen, many staff and ground staff have already prepared for the drone.

It was the first time for all the people in the base to see such a stylish drone, and their hearts were surging, but seeing that there were many people, it was not good to speak loudly, so they whispered with the people next to them.

"The test is done after the last test."

The communication between the base and the military factory has long been linked, and the relevant staff in the picture began to leave, and the report of the military factory staff came from the channel.

At this time, Xu Ziling had already sat down in front of the big screen, and what was in front of him was the control terminal of the drone.

"The drone enters the runway."

Hearing the report, he immediately gave the order.

"Roger."

The voice fell, and immediately saw in the picture that the tractor on the side started to start, came to the front of the nose of the drone, and quickly pulled the plane to the outside of the hangar.

As soon as the drone entered the runway, the tractor in front of it quickly let go of the plane and returned to the hangar.

Seeing that there were only drones left on the runway, Xu Ziling immediately turned on the control terminal and began to connect with the drone through satellites.

The terminal system was turned on, and the signal on it indicated that the connection was normal, and he immediately controlled and started the UAV avionics system to quickly check the data of the aircraft.

After doing all this, the results are normal, and then the drone is ready to take off.

The engine turned on, the brakes were released, the throttle was pushed, and after a few movements, the plane began to taxi down the runway.

As the throttle continued to increase, the tail vent of the drone spewed out a huge tongue of fire in the dark night, and the entire plane also ran at a very fast speed on the runway.

Pull up the cāo pole, turn the directional wings, and the drone takes off on the runway.

Flying quickly in the sky, the plane quickly jumped over the range of the airport runway, and as it continued to climb, Xu Ziling controlled the plane to retract the landing gear.

At this time, only a little fire in the night sky could be seen in the surveillance footage of the military factory airport on the big screen.

When the plane reached an altitude of one thousand meters, he controlled the drone to adjust its course and input the coordinates of the Sword base in the navigation system.

When he climbed to an altitude of 8 kilometers, he began to set up automatic cruise control and let go of the manual control.

It was only then that he realized that there was no difference between a drone flying at night and flying in the daytime.

When the plane was preparing before takeoff, he had to look at the camera equipment on the plane.

I usually don't pay attention to it, but when I look at it today, I realize how different it is from traditional equipment such as infrared at night.

Just think about the infrared camera, as soon as it is turned on at night, due to the problem of light, the picture display is blurry, and the face is single.

However, as soon as you open the "Eagle Eye", the picture it scans has an automatic lighting effect, which looks the same as the one scanned during the day.

In other words, even if you just look at the radar scan and cāo vertical drone, it is no different from controlling it during the day.

"I heard this thing is fast?"

Yang Kaiming, Li Cheng, and Lin Jianbin stood together, watching the drone take off, Li Cheng pushed Lin Jianbin next to him and asked, because among the three of them, only this guy had seen it with his own eyes.

"There's a flight speed on it, look for yourself, where is the upper right corner, do you see it?"

Lin Jianbin pointed to the big screen, and Xu Ziling turned over from the control terminal and told Li Cheng,

"Now it's almost Mach 2, looking at the speed has not changed, it should be entering the cruise at a fixed speed, the fastest can reach Mach 5 without loss, and it will only take half an hour to get to the base."

"Hiss......"

Yang Kaiming and Li Cheng both heard what he said, and gasped, the intelligence in the base was only about the drone in the East China Sea, and there was no relevant flight data.

In the past two days, several people were also busy taking Lin Jianbin around, but they didn't ask about it carefully, and they were really shocked to get such an answer at this time.

"I heard that the stealth drone of the Mi people can reach Mach 9 at the fastest, but that is the burst speed, and the non-destructive flight is only Mach 4.

"Catch up with Mao, what are they called stealth, but unfortunately there is no satellite picture this time, otherwise you must see what stealth is."

"What's that saying?"

The voices of several people gradually became louder, and many people heard it, looking at the meaning of Lin Jianbin's words, they realized that there was a lot of meaning in this stealth function.
