The entire body is jet black.

The fuselage lines are as sharp as a shark's dorsal fin, and the matte black coating gives it a strong sense of oppression.

A massive single nozzle below the twin vertical tails.

The nearly invisible solar energy panel coating on the body of the Viper Unmanned Combat Aircraft grants it exceptional endurance, allowing it to theoretically stay aloft indefinitely, as long as it remains undamaged.

And...

The four large caliber cannons mounted under the wings.

Two words.

Perfect!

"Phew..."

Chen Mang exhaled lightly, looking at the fighter in front of him, a sense of satisfaction welling up in his heart. The strongest aspect of this drone is not its Level 20 attack strength, but its unlimited endurance.

Once it takes off, it never needs to land again.

If there had been such a thing in the last world, if it were cheaper to build, he couldn't imagine how the battles would have intensified...

The next moment—

"Warning, warning..."

The piercing alarm sounds echoed throughout the entire Fixed Star carriage. The incandescent lights on the sides and ceilings of the carriages starting from Carriage 10 began to flash red warning lights rapidly.

These were the life accessories he had just created using the "Mechanical Heart."

This way, when the fighter takes off in the future, the residents will know to evacuate the carriage quickly.

The subsequent carriages have also been cleared out.

The two "Cosmic Receivers" in Carriage 12 were placed on both sides of the carriage, and the "40-tube Sakura Fall Rocket Cannon" in Carriage 13 was the same. As for the "Earth-Burst Missile" in Carriage 14... there's only one launcher.

No missiles.

The missiles can be created on demand when needed, no rush, as they are made instantly, there's no need for storage.

Even Carriage 15, the "Breeding Carriage," has been cleared of ammunition, with the fridge and other items moved to the sides, and the rear door opened.

"Boom!"

Accompanied by a sudden outbreak of faint blue tail flame, the air distorted in the heat waves, resembling Satan's jeer.

This Level 20 Viper Unmanned Combat Aircraft began to accelerate rapidly, speeding up progressively along the interior of the carriages, swiftly moving past Carriage 11, Carriage 12, Carriage 13...

As it reached Carriage 15.

The nose began to lift.

The speed reached its peak, the sound of air being torn resonating inside the Fixed Star.

Under the jarring sonic boom, it quickly flew out of the Constant Star Train, and after detaching from the train, it began to ascend rapidly at nearly a right angle.

The advantage of not having a pilot is that many high-difficulty maneuvers don't require considering the body's ability to withstand them.

The drawback is that it's relatively rigid, only able to operate based on programmed instructions, unable to respond adequately in the first instance.

...

On the wasteland.

Chen Mang stood to the side of the Constant Star Train, looking up at the Viper Unmanned Combat Aircraft constantly circling overhead, as long as it's not destroyed, this drone will continue spinning in the air.

Of course, this assumes it doesn't encounter polar night or perpetual night.

With a Level 20 attack strength, it poses a threat to many high-level trains and monsters.

If there were hundreds of such fighters hovering in the sky, there's nothing more to say, it would fill the security feeling to the brim, especially since its speed is shared with the train, boasting a maximum speed of 5040km/h, along with unlimited endurance, being called the overlord of the sky is no exaggeration.

He has embedded it with 2 Level 4 Energy Stones crafted from 1 million units of iron ore.

To maintain a Level 20 attack intensity, the Level 4 Energy Stones can supply the four cannons with continuous fire for 30 seconds, thanks to the supermodel effect of half ammunition consumption, using it is still quite energy-efficient.
