Thought acceleration?
This upgrade actually had an additional characteristic.
It was something he had not anticipated.
If not for the fact that he had just woken up.
He really wanted to try out the effects of this new characteristic.
Other than that.
The appearance of the entire equipment had also changed.
The appearance and the internal equipment should have been adjusted as well.
Anyway, the equipment now looked much more advanced. The external materials also felt excellent.
In that case...
Leveling up to level four was a hurdle.
Items that reached this level would significantly improve and increase their characteristics.
Thinking of this…
Tang Rui was a little excited.
This was because his drone was only a few thousand experience points away from leveling up.
Based on the previous experience, points gain speed, he calculated.
He only needed to fly for another three hours tonight to upgrade the drone.
Putting down the subconscious learning device, he quickly changed his clothes, packed his things, and left with the drone.
He drove out of the neighborhood.
He looked at the food stalls by the roadside and felt a little greedy.
He was not hungry.
But his stomach was definitely empty.
After all, he hadn't eaten dinner.
However, compared to the drone upgrade, eating was a small problem.
They arrived at the gas station at the foot of the old mountain.
When Tang Rui was buying fuel, he conveniently bought three bags of bread and a bottle of drink at the supermarket at the gas station.
When hungry, he would just casually eat a mouthful to fill his stomach.
They arrived at the observation platform again.
Tang Rui skillfully parked the car and placed the equipment properly.
The engine roared.
The drone flew into the sky.
He activated the ground search mode.
Tang Rui began to search for targets in the woods, beside the river embankment and the haystack.
After all, at this time, many people who sought excitement would go to these places to exercise.
He anxiously searched for more than half an hour but found nothing.
What was going on?
What day is it today? Why is there no one here?
Tang Rui controlled the unmanned machine to wander around these places a few times, but he found nothing.
This was very strange.
Could it be that they had changed places?
He controlled the drone and began to scan the woods on both sides of the road along the provincial and national roads.
In the end, he wandered around for a long time.
The drone's fuel was almost exhausted, but it did not find anything suspicious.
He controlled the drone to return.
Add oil.
It took off again.
This time, Tang Rui was too lazy to look for it. He controlled the drone to fly over the Yangtze River and began to pull various maneuvers.
He even controlled the drone to shuttle around the pier under the Yangtze River Bridge.
Due to the continuous maneuvering and activation of the afterburner, the fuel was consumed in no time.
In less than 40 minutes, the drone ran out of fuel and had to return.
Tang Rui filled the drone with fuel again and controlled it to take off.
This time, he was too lazy to control it. He marked a few points on the map and let the drone cruise automatically.
He took out some bread and drinks and started eating dinner.
In the blink of an eye, it was 1:27 am.
After more than three hours of flight, the drone landed on the observation deck.
Tang Rui ran over anxiously.
He looked at the system panel of the drone.
[Item: Exquisite fixed-wing drone +3]
[Experience: 1259/12000 (Upgradeable)]
[Enhancement: Body, avionic, engine, energy]
[Origin Points: 12 (Can be strengthened)]
He finally had enough experience points.
Tang Rui was so excited that he forgot the current environment and directly clicked to upgrade.
After ordering, he regretted it.
Fortunately, there were no surveillance cameras around the observation platform, and there was no one within a two-kilometer radius.
A golden light flashed.
The drone was upgraded.
[Item: Perfect reconnaissance drone +4]
[Experience: 959/26000]
[Enhancement: Body, avionic, engine, energy]
[Characteristic: High-precision scanning]
[Origin Points: 12 (Can be strengthened)]
This upgrade… It could be said that the drone was completely reborn.
Other than the changes in the data on the system panel, the entire drone had changed greatly.
From the original airplane model body, it directly turned into a long wave rider body.
The length of the drone had increased from 1.1 to 2.3 meters.
Furthermore, the entire body of the mecha was also made invisible and designed for high speed.
Therefore, the wings didn't grow longer. Instead, they became shorter.
From normal wings, it was upgraded to a variable-sweep wing.
The twin tails disappeared.
The normal air intake became a DSI air intake.
As for the internal changes, it was impossible to tell just by looking at the hardware.
Tang Rui looked at the brand-new drone and felt a little excited.
It was incredible, to say the least.
This exterior design was simply amazing.
To brag, this design could be directly enlarged to a full-sized supersonic stealth strategic bomber.
Tang Rui poured the remaining half a barrel of fuel directly into the drone.
He couldn't wait to try the upgraded drone.
In the end, half a barrel was filled.
Lets not talk about filling up the previous drone.
The original drone could only take one barrel of fuel at most.
Now, the capacity of the fuel tank had increased by more than five times.
This meant that the drone's flight time had been extended.
As for how much it would be extended, it would depend on the fuel consumption.
After refueling.
Tang Rui returned to the computer.
It was only then that he realized that even the image on the computer screen had changed.
Originally, the drone's camera could only capture high-definition images.
The image displayed on the computer screen was now at 4K resolution.
This improvement in image quality meant that the drone's optical equipment and image processing capabilities had become stronger.
He briefly checked the operating system interface and started the engine.
Buzz... Boom!
Blue-white exhaust flames spurted out, directly drawing out clear Mach Rings.
He released the brakes.
The drone launched and rushed out.
Fortunately, he was mentally prepared and pulled the lever.
Whoosh!
The drone flew into the sky.
The scene that Tang Rui saw on the screen was like watching a blockbuster.
That feeling was very satisfying.
Activating the electro-optical system, he activated the full-frequency scanning mode.
He wanted to know how powerful the high-precision scanning feature on the system interface was.
In the next second.
All sorts of notifications appeared on the screen.
He tapped on one of the markings.
Instantly.
The marked picture zoomed in, and a gecko lying on the wall appeared on the screen.
Suck!
Tang Rui took a deep breath.
This was a little f*cking exaggerated.
No wonder it was called high-precision scanning. This precision was simply too high.
The picture displayed on the computer screen even showed the stripes on the gecko's body clearly.
It could even continue to enlarge.
Tang Rui controlled the drone to fly to the river's surface. After crossing the third bridge, he activated the afterburner.
In the blink of an eye, the drone exceeded the speed of sound, reaching Mach 2.
At this speed, Tang Rui turned on the ground scanning system again and began to scan and take pictures of the woods on both sides of the river embankment.
The effect was still the same.
The photos taken did not become blurred because of the increased speed of the drone.
After testing the electro-optical system, he looked at the data of the fuel tank.
He could still fly for more than ten minutes.
However, this meant he couldn't use the afterburner while flying at Mach 2.
He turned off the afterburner.
He looked at the drone's location and the surrounding environment before pulling the control stick.
The drone began to ascend at a 75° angle.
300 meters.
500 meters.
1000 meters.
Di di di…
At this moment, the system sent an alarm. The drone's radar had detected a fighter jet.
The fighter jet was right above the drone.
The system had already marked it.
Target lock?
No.
No target lock.
Tang Rui's hand trembled, and he hurriedly lowered the drone's altitude.
Then, he dove into the forest beside him and flew close to the road.
He was scared to death.
Playing with drones privately, not filming classified locations, not interfering with aviation order… if caught, at most, he would be re-educated.
However, if they were to lock onto a fighter jet with radar and fire control, things would get out of hand.
Fortunately, the drone had a stealth function after the upgrade.
Otherwise…
Based on the drone's height, ground, and airborne radars would have long scanned it.
They circled at a low altitude for five minutes.
After ensuring the fighter jet above him had left, he controlled the drone to return.
