Thinking faster?

In this upgrade, there is even one more feature.

This is something he did not expect.

If you hadn't just woken up.

He really wanted to see what this new trait could do.

Besides.

The appearance of the whole device has also undergone new changes.

Maybe not only the appearance, but also the equipment inside should have been adjusted.

Anyway, the current equipment looks much more advanced, and the external materials have become very textured to the touch.

Let's put it this way.

Reaching level four is a hurdle.

Items that reach this level will be greatly improved and their characteristics will be increased.

Come to think of it.

Tang Rui was a little excited.

Because of his drone, he is just a few thousand experience points short of being able to level up.

Calculated based on the previous experience gain speed.

He only needs to fly for about three more hours tonight to be able to upgrade the drone.

Putting down the subliminal learning device, he quickly changed his clothes, then packed his things and went out with the drone.

Drive away from the complex.

He looked at the food stalls on the side of the road, a little greedy.

Hungry is not hungry.

But the stomach is definitely empty.

After all, he didn't eat at night.

However, compared to drone upgrades, eating or something is a minor problem.

Come to the gas station at the foot of the old mountain.

When Tang Rui was buying fuel, he bought three bags of bread and a bottle of drink at the supermarket at the gas station.

When you're hungry, just take a bite and fill your stomach.

Come to the observation deck again.

Tang Rui skillfully parked the car and placed the equipment.

With the roar of the turbojet engine.

The drone rushed into the sky.

Turn on the ground search mode.

Tang Rui began to look for targets in the woods, by the river embankment, and by the haystacks.

After all, at this time, there are many thrill-seekers who will run to these places to do sports.

He searched expectantly for more than half an hour, but found nothing.

What's going on?

What day is it, why is there no one?

Tang Rui controlled the drone and walked around these places several times, but found nothing.

It's weird.

Did you change places?

He took control of the drone and began to scan the woods on both sides of the road along the provincial and national highways.

As a result, it took a long time.

The drones were running out of fuel, and nothing suspicious was found.

Control the drone to return.

Add oil.

Take off again.

This time, Tang Rui didn't bother to look for it, he controlled the drone to the sky over the Yangtze River and began to fly various maneuvers.

Even control the drone, under the bridge of the three bridges of the Yangtze River, around the pier of the S-shaped shuttle.

Due to the continuous maneuvering action and the opening afterburner, the fuel is consumed quickly.

Less than forty minutes.

The drone ran out of fuel and had to return for refueling.

Tang Rui filled up the drone again and controlled it to take off.

This time, he didn't bother to control it, and directly marked a few points on the map and let the drone carry out automatic cruise.

He took out bread and drinks and began to eat dinner.

In the blink of an eye.

It was 1:27 a.m.

After more than three hours of flying, the drone landed on the observation deck.

Tang Rui ran over eagerly.

Looking at the system panel of the drone.

[Item: Exquisite fixed-wing drone +3]

[Experience: 12959/12000 (Upgradeable)]

[Enhancement: Airframe, Avionics, Engine, Energy]

[Source Point: 12 (Enhanced)]

Experience points are finally enough.

Tang Rui excitedly forgot about the current environment and clicked upgrade directly.

After ordering it, he regretted it.

Fortunately, there was no surveillance around the observation deck, and there was no one within a two-kilometer radius.

With a golden shimmer flashing.

The drone upgrade is complete.

[Item: Perfect Recon Aircraft Drone +4]

[Experience: 959/26000]

[Enhancement: Airframe, Avionics, Engine, Energy]

[Feature: High-precision scanning]

[Source Point: 12 (Enhanced)]

This time upgrade.

Drones can be described as a rebirth.

In addition to the data changes on the system panel, the entire drone has changed greatly.

From the original model airplane, it has directly become a long wave-riding body.

The length of the body has changed from the original one meter one and two to the current two meters and three five.

And the entire body is also made of stealth processing and ultra-high-speed design.

So instead of getting longer, the wing got shorter.

From a normal wing, upgraded to a variable swept wing.

The twin tail wings disappeared directly.

The ordinary air intake has become the DSI air intake.

As for the internal changes, you can't see it at all just by looking at the hardware.

Tang Rui looked at the brand-new drone, a little excited.

It's so handsome.

This shape design is simply amazing.

To put it mildly, with this shape design, it can be directly enlarged and used to engage in supersonic stealth strategic bombers.

Tang Rui poured the remaining half a barrel of oil directly into the drone.

He couldn't wait to try out the upgraded drone.

As a result, half a barrel of oil was filled.

Not to mention filling up the tank, not even a tenth of it.

The original drone could only add a barrel of fuel at most.

And now, the capacity of the tank has directly increased by more than five times.

This means that the launch time of the drone has been extended a lot.

How much to extend, you also need to look at fuel consumption.

After refueling.

Tang Rui returned to the computer.

At this time, he realized that even the picture on the computer screen had changed.

Originally, the camera of the drone could only shoot high-definition.

And now the picture displayed on the computer screen directly becomes 4K.

This improvement in image quality shows that the optical equipment and image processing capabilities of drones have become stronger.

He briefly checked the interface of the operating system and started the engine directly.

Airplanes...... Rumble!

The blue-white tail flame erupted, directly pulling out a clear Mach ring.

Let go of the brakes.

The drone ejected and started and rushed out directly.

Fortunately, he was mentally prepared and pulled the joystick directly.

Shout!

The drone rushed into the sky.

The scene Tang Rui saw from the screen was like watching a blockbuster.

It was a very good feeling.

Start the photoelectric system and turn on the full-range scanning mode.

He wanted to know how strong the high-precision scanning feature on the system panel was.

The next second.

A variety of scan result prompts appear on the screen.

He clicked on one of the markers.

Moment.

The picture of the marker keeps zooming in, and a gecko lying on the wall appears on the screen.

Suck!

Tang Rui took a deep breath.

This Nima is a bit exaggerated.

No wonder it's called high-precision scanning, this accuracy is simply amazing.

The photos displayed on the computer screen show that even the markings on the gecko's body can be clearly seen.

You can even zoom in.

Tang Rui controlled the drone to fly to the river, and after crossing the three bridges, he turned on the afterburner.

In the blink of an eye.

The drone flew faster than the speed of sound, reaching Mach 2.

At this speed.

Tang Rui turned on the ground scanning system again and began to scan and shoot the woods on both sides of the river embankment.

The effect is still the same.

The photos taken did not become blurry because of the increased speed of the drone.

After testing the optoelectronic system, he glanced at the data from the tank.

It can fly for more than ten minutes.

But you can't turn on the afterburner, and you keep flying like this at Mach 2.

Turn off afterburner.

After glancing at the location of the drone and the surrounding environment, he directly pulled up the joystick.

The drone, at an angle of 75 °, began to rise.

300 meters.

500 meters.

1000 meters.

Di Di Di ......

At this time, an alarm was sent from the system, and the drone radar scanned a fighter jet.

And this fighter jet, right above the drone.

It has been flagged by the system.

Whether or not to make a lock.

No.

Not locked.

Tang Rui's hand shook and he hurriedly controlled the drone to reduce the altitude.

Then burrow into the woods next to it and fly close to the road.

Scared to death.

Playing with drones privately, not filming secret locations, and not interfering with aviation order, if you are caught, it will be an education at most.

But if a fighter is subjected to radar locking and fire control irradiation, then the matter is a big deal.

Fortunately, after this upgrade, the drone has a stealth function.

Otherwise.

Just now, the flight altitude of the drone has long been swept by the ground radar and the airborne radar of the fighter.

It was a five-minute walk at a low altitude.

After making sure that the fighter overhead had left, he controlled the drone to return.
