While Orlando and the others were eavesdropping, Lydia, who was controlling the first-generation fighter plane in the sky, gradually became familiar with the big toy under her, and soon began to test the combat! Lydia pressed the wrench of the engine control directly to the bottom, increased the speed to the limit, and then dived down.

The entire fuselage was like a giant eagle, falling rapidly from the sky, causing a huge sound of breaking through the air, but the next moment it was drowned out by the sound of machine guns on both sides of the wings!

The stone road surface reinforced by magic was immediately dotted with potholes. Lydia stretched the aircraft with great excitement, changing from a rapid descent to a rapid ascent. The fighter jet flew by only 30 meters above the ground. Seeing Orlando and the others, they were terrified, fearing that this thing would lose control and fall headfirst...

Their worries did not come true. Although it was Lydia's first time to fly a real fighter jet, her operating skills were not weak. She easily completed the dangerous maneuver of flying close to the ground. Before completely leaving the ground, she opened the bomb bay at the bottom of the fuselage and dropped several incendiary bombs...

Accompanied by bursts of piercing explosions, about a quarter of the runway was instantly covered by fierce white phosphorus fire! In order to pursue the ultimate speed, the fighter's load capacity is limited, and the shrapnel it carries is only enough for this one attack.

However, according to their original design, this thing was not supposed to have a bomb bay. After all, the main mission of the first-generation fighter jets was to eliminate threats from the air, and the rest could be left to the airship.

It was obviously made to deliver another killer weapon...

At this moment in the valley, Vittorio, Orlando and a group of alchemists who were watching were extremely satisfied with the performance of this new aircraft after watching for a while.

Only Lin En looked at the runway on fire and dotted with craters, with a helpless look on his face.

If you blow up the runway, what about landing? Lydia, who was admiring the shooting results in the sky, suddenly thought of this. As the designer and maker of the fighter blueprint, Lydia naturally knew that this thing must take off and land on a very flat road. If you are not careful, the end result will be the destruction of the plane and the death of people.

Except for the newly repaired runway using magic, this valley is covered with soft and uneven soil and blocked by trees. It is not a place to land at all.

Lydia had no choice but to continue hovering in the sky, waiting for the wizards below to repair the runway. However, after circling in the sky for several times, there was no movement.

Just as she was anxiously preparing to fly back to the capital and make an emergency landing in the city square, Lin En used magic to extinguish the burning flames and repair the damaged runway.

After the fighter jet successfully landed, Lydia, who had been so excited before, was now only filled with fear.

"Fighter jets are extremely fast, which is their advantage, but also sometimes a disadvantage. At extremely high speeds, they may even crash into a flying bird and die..." Lin En reminded seriously.

Lydia's talent in engineering is self-evident, but she tends to lose her mind when she is happy, which is a big taboo for a pilot.

We should consider adding a parachute or something in case of emergency, and combined with magic such as slow fall, it will allow the pilot to save his life when encountering danger.

Most of the time, the person who controls the weapon is much more important than the weapon itself...

This is especially true with higher levels of industry.

"This new type of aircraft needs to rely on a runway to take off and land, which is a big flaw." Vittorio suggested that since the aircraft is made of metal, perhaps they could try adding electromagnetic magic to the fuselage and use electromagnetic propulsion to send the fighter directly into the sky.

Those that can use electromagnetic catapult technology are hypersonic fighter jets with speeds of several Mach or even dozens of Mach per second. Using jet propulsion, they can instantly accelerate to a level sufficient to support the flight of the aircraft.

It’s better not to use this kind of propeller plane!

Seeing that Lin En rejected his proposal, Vittorio didn't care. What really made him feel a little confused was that Lin En felt that the new aircraft with a speed of 360 kilometers per hour was too slow.

If this is called slow, then what else can be called fast? Can we expect this flying steel box to run as fast as light and circle the continent seven and a half times per second? Orlando and others also put forward various suggestions for improvement, which is why Lin En invited them here.

Some of these suggestions are out of this world and completely illogical, but some of them are practical ideas.

For example, optical stealth has been achieved on airships and laser launchers have been added to fighter jets.

Both of these can significantly improve the fighter's survivability and combat capability without adding too much weight and affecting the aircraft's performance.

The happiest person was naturally Lydia. In her opinion, the biggest drawback of this fighter was not that it needed a runway to land, but that its combat endurance was too poor!

There is only one shrapnel shell available. If the machine gun is used continuously, the ammunition is only enough for one minute. After it is used up, it loses its ability to attack and can only be used for reconnaissance. Otherwise, it must return for resupply.

This is what they call flying for a few hours and being happy for a minute...

But it would be different if it was equipped with a laser launcher. After using up the ammunition, it could also engage in close combat with the enemy, just like the bayonet on a musket.

That's the kind of battle that can make people's blood boil! With the ideas and suggestions of a group of alchemists, the magic improvement plan was produced in just two hours.

Of course, drawing the alchemical array on the machine and doing subsequent debugging would take another week.

"Then we won't be able to catch up with the next battle." Lydia said rather depressedly. She stayed up late for several days rushing to make it just to catch up with the first battle!

"To recapture the kingdom, we don't need high-end things like fighter jets." Lin En said with a smile. Their opponents were just a group of kingdom nobles who jumped back and forth and changed their attitude according to the situation.

When we actually invade the empire, that’s when this thing will show its power.

And what's the use of one fighter? If you want to ensure air superiority, you need at least one formation! (End of this chapter)
