Tang Rui controlled the drone to ascend directly to an altitude of 5000 meters.
This altitude was something he had never flown at before.
Securing the airspace was great; they could fly freely.
Once reaching the altitude of 5000 meters, he activated the drone's electro-optical system.
Beep, beep, beep...
The next second, warning symbols began flashing on the screen.
What was going on?
Tang Rui was momentarily puzzled, but he quickly tapped on the keyboard.
Swish!
The red dots on the screen refreshed and turned into an image.
"What the heck is this, radar vehicles?"
Seeing several military vehicles in the picture, he was dumbfounded.
One had a spherical top, another a rectangular radar array, and the third a circular disk.
Three radar vehicles, three different radar models.
On the computer screen, it clearly displayed that all three radar vehicles were in operational mode.
The radar frequencies, bands, and radiation intensities were all precisely detected by the drone's system.
Moreover, these vehicles were just three kilometers away from Zijin College.
"Damn it... These are military radar vehicles. How come they're operating in the city?"
"That rectangular radar array seems to be a low-altitude warning radar, specifically used to target drones."
"Look at the radar frequencies and bands; this seems to be pulse-Doppler radar."
"The radiation feedback is very clear. If they fire an anti-radiation missile, it would be interesting."
As the last person spoke, everyone looked at him.
'Young man, your ideas are quite bold.'
"Seems like these three radar vehicles are using our drones as targets. Is this some kind of exercise?"
"Our instructor didn't mention this. Could it be... we're being taken advantage of?"
"How about we fly over and take a look?"
"Sure, let's fly over together: one high, one medium, and one low. Jets go for a direct acceleration charge, turbofans flank from both sides, and propellers maneuver at low altitude."
"No problem, let's do it."
"Tang Rui, give us directions. We're up."
"Charge!"
After a brief assignment of tasks, everyone acted according to their aircraft types.
They were all young people.
If they were being taken advantage of, so be it.
They put their words into action.
From Tang Rui's drone's perspective, the previously scattered flying models in the sky began to organize effectively.
"Are you sure this won't cause trouble?" Li Shuyao asked quietly, seeing the group of excited people.
"What could happen? Our airspace is centered around the sports field, with a flight radius of five kilometers. The radar vehicles are within our airspace. What's the problem if we fly over there?" Tang Rui didn't mind at all.
After such an incident, it wouldn't be them who would be embarrassed.
No one would take a group of college students too seriously. He felt a bit sorry for the soldiers on the radar vehicles.
They might receive a dressing down when they return.
As the group of model aircraft began an organized charge, the soldiers inside the command vehicle immediately reported, "Report, our location has been detected, and the drone fleet is moving towards us in an organized manner."
"Discovered?"
The technician was a bit puzzled.
He looked outside the window, and the radar vehicle was completely concealed by the trees.
Their current location was practically impossible to detect unless observed from a high altitude. Even if the model aircraft carried cameras, they wouldn't be able to spot them here.
Moreover, none of the previously launched model aircraft were flying in their direction.
So, how did they get exposed?
"Thirteen drones shot down, both sides' drone squads have broken through the second defense line."
"Left-wing drone squad has been eliminated. The nearest drone is at a distance of 823 meters from our location."
"Right-wing drone squad has been annihilated. Most drones are approaching the third defense line."
As the three soldiers reported, the middle-aged military personnel and the technician's expressions eased slightly.
But the next moment, an alarm sounded from the radar, indicating that enemy drones had breached the final defense line.
In a battlefield scenario, this distance practically meant they were face-to-face with the Grim Reaper.
Though if they had equipped the vehicle with close-range defense weapons, it might not necessarily lead to a disaster.
Still, the situation was very dangerous.
As expected, more than a dozen red dots appeared on the screen, now less than 230 meters away from them.
"Why wasn't it detected earlier?"
"Report, the enemy drone squad is executing a low-altitude maneuver, using buildings to conceal themselves."
If it weren't for their location, where there were no buildings around, they wouldn't have been able to detect these dozen propeller drones.
These drones were flying too low, just five meters above the ground, using buildings for cover.
Of course, they were able to do all this because Tang Rui had provided them with a full map cheat.
"Report, the simulated destruction by the close-range defense weapons has stopped the enemy drone squad at 196 meters."
The technician breathed a sigh of relief after hearing this.
If they had been breached, he would have been humiliated.
Fortunately, the close-range defense weapons were quite deadly against these drones.
After hovering around the radar vehicle for a while, the group of model aircraft finally flew away.
The middle-aged man in military uniform opened the vehicle door and exited the command car.
The technician followed suit.
"To be honest, this test wasn't quite fair for our drone defense system. After all, we couldn't use the electronic jamming system. Once we activate that system, the drone squad wouldn't even get close to the third defense line."
"What if the enemy uses Witness and Spring Knife drones?"
"It won't work. Any cruise missile won't escape the monitoring of this system."
As soon as the technician finished speaking, they heard some commotion above them.
Looking up, they saw a futuristic-looking drone hovering over the radar vehicle.
"Do we have any drones hovering above us?"
The middle-aged man in military uniform glanced up and asked the soldiers inside the vehicle.
"Report, no, the nearest drone to our location is two kilometers away."
After hearing the soldier's response, the man remained silent, just watching the technician who had been boasting earlier.
"Impossible, absolutely impossible."
After a moment of confusion, the technician quickly rushed back into the command car and leaned in front of the screen, observing the radar display. Then he stuck his head out of the vehicle and looked at the drone above.
Tang Rui controlled the drone to circle around the radar vehicle for a while, taking several pictures before controlling it to fly away.
With its powerful engine and surging power, the drone broke the sound barrier and flew away at high speed in the distance.
The sonic boom startled the baffled technician.
"Contact the radar station immediately and scan the Xianlin airspace. There's a supersonic stealth drone flying over Xianlin."
After hanging up the phone, he sat back in the vehicle's passenger seat.
"Go to Zijin College."
Boom!
The driver started the vehicle and drove directly towards Zijin College.
