As for its battery life performance?
First of all, its maximum flight speed is 350 kilometers per hour, and its maximum endurance time is 6 hours.

Of course, this battery life will decrease as the number of times the electromagnetic gun is used to fire bullets increases, after all, the electromagnetic gun uses electrical energy.

This 'Hummingbird reconnaissance and strike UAV' is a UAV specially designed for ground combat. Its development purpose is to cooperate with the 'ground-air-space integrated defense system' to carry out joint combat missions.

The main task is to eliminate the remaining local soldiers who refuse to surrender, with the goal of completely eliminating the ground soldiers or defeating them and forcing them to surrender voluntarily.

The combat mode is to first use the "ground-air-space integrated defense system", that is, to use a large number of second-generation electromagnetic guns to carry out beyond-visual-range strikes.

Completely destroy the enemy's important buildings, armored vehicles, missile vehicles, tanks, self-propelled artillery, armed helicopters and other heavy firepower.

At this time, the soldiers in the enemy area who have lost their heavy firepower support are unlikely to completely collapse, and there is a high probability that they will still insist on stubborn resistance.

At this time, the 'Hummingbird UAV' will be dispatched to carry out the task of clearing out the remaining resistance soldiers."

Having said that, Lin Feng paused for a moment and then continued:

"To achieve this, we must give the Hummingbird reconnaissance and strike drone powerful detection capabilities, precision strike capabilities, flexible mobility capabilities, and anti-missile capabilities.

After all, even if they lose heavy firepower support such as tanks, missile vehicles, armored vehicles, and self-propelled artillery, ground soldiers may still have a certain air defense and counterattack capability.

Therefore, I miniaturized the technology of the electromagnetic gun and installed it in this 'Hummingbird reconnaissance and strike drone'."

Having said this, Lin Feng stopped talking, and the video screen turned into a highly realistic battlefield scene simulated by the artificial intelligence Jarvis through the Unreal 4 game engine.

When netizens saw this, they became quite curious and watched, wanting to know how powerful this "Hummingbird reconnaissance and strike drone" was.

At this time, the picture that appears on the screen is a picture of a military camp, in which a large number of soldiers, tanks, self-propelled artillery, armed helicopters, and anti-aircraft missile vehicles can be seen.

Then countless whistling sounds were heard in the sky, and countless guided artillery shells with a speed of up to 25 times the speed of sound instantly destroyed everything in the military camp.

Those armed helicopters, tanks, missile vehicles, armored vehicles, command centers, radar vehicles, off-road vehicles, etc. all suffered devastating blows.

After this devastating blow, huge holes more than ten meters deep or huge craters left by the explosion of 124 kg high-explosive shells were left at the site.

After this round of devastating blows, some of the surviving soldiers gathered together again, seemingly wanting to organize a counterattack.

Then, in the distance, 50 "Hummingbird UAVs" were rushing towards us at a speed of more than 350 kilometers per hour.

At this time, dozens of soldiers carried the famous Stinger individual air defense missiles and fired them at the "Hummingbird UAV" in the distance.

Then the Stinger individual air defense missile flew towards the distant "Hummingbird reconnaissance and strike drone" at a speed of 2.2 with flames.

At this moment, an electromagnetic gun about 1.5 meters long at the bottom front of the "Hummingbird Reconnaissance and Strike Integrated UAV" in the distance fired a slender bullet marked in the video as 5 times the speed of sound, 12.5mm long and 4.5mm wide.

At such a close distance, the individual anti-aircraft missile, which could only go straight to the face, had no power to resist at all and was directly blown up in mid-air.

But at this time, the electromagnetic gun of the "Hummingbird Reconnaissance and Strike UAV" did not stop attacking.

In fact, while firing bullets to blow up the individual air defense missile, its muzzle had already begun to fine-tune and turn towards the next target.

In this slowed-down video, you can see that each time it fine-tunes, it aims at a soldier and fires a bullet at 5 times the speed of sound. Then it fine-tunes the aim at the next target, and after the bullet at 5 times the speed of sound is fired, it fine-tunes the aim at the next target again, and repeats this process over and over again.

The phenomenon of such a person rewarding a bullet traveling at five times the speed of sound is not an isolated case.

In fact, the bullets fired each time by these more than 50 "Hummingbird reconnaissance and strike drones" are actually allocated in proportions by the artificial intelligence Jarvis's clones.

Therefore, there will never be a phenomenon where multiple "Hummingbird reconnaissance and strike drones" attack a target at the same time, wasting bullets and energy.

As for the result?
After the video introduced the slow-motion shots of "one bullet per enemy" and "multiple drones working together", the video playback speed soon returned to normal.

At this time, netizens who were watching the video saw a shocking scene.

They saw the soldiers in the video who raised their guns to fight back, and suddenly they all shook, and parts of their body tissues were blown into a bloody mist by bullets traveling at five times the speed of sound.

At this time, the remaining soldiers who were not hit by bullets were naturally frightened and began to flee, but it was all in vain.

Because their escape speed can never match the flying speed of a bullet at 5 times the speed of sound.

In the end, when these 50 "Hummingbird reconnaissance and strike drones" flew over the military camp, they left behind hundreds of soldiers' bodies.

After that, the more than 50 "Hummingbird reconnaissance and strike drones" turned around and started harvesting again.

During this process, some of the soldiers wanted to rely on buildings or trees to fight back or hide.

But in reality, none of them are useful, because the "Hummingbird reconnaissance and strike drone" marked in the video has multiple detection methods such as radar, infrared vision, high-definition slow-speed panoramic camera, etc.

What’s even more terrifying is that the detection systems of these 50 ‘Hummingbird reconnaissance and strike drones’ are actually connected to the Internet.

Therefore, the data of these 50 "Hummingbird reconnaissance and strike drones" have been fully digitized in front of the artificial intelligence Jarvis's clone.

In the end, everyone knows where every soldier is and where they may appear, because the artificial intelligence Jarvis's clone has already arranged a death order for them.

Finally, the 5 times the speed of sound bullet fired by the super electromagnetic gun has super strong penetrating ability. Those big trees or walls cannot block this 12.5 times the speed of sound bullet that is 4.5mm long and 5mm wide.

So what was shown before people's eyes was that in less than five minutes, all the thousands of remaining resisting soldiers in the entire military camp were shot dead on the spot!

Witness the battlefield scene simulated by Unreal 4 game engine in the video.

All netizens who were watching the video fell into silence, their eyes wide open, and many people couldn't help swallowing.

"This can't be true, right? The results are too exaggerated!"

"It's terrible. It's really too terrible."

"One bullet per soldier. It's fair indeed."

"The speed of the bullets from the electromagnetic gun of this Hummingbird drone is 5 times the speed of sound. How can a bulletproof vest intercept it? Isn't this too exaggerated?" (End of this chapter)
