"Start the engine! Start the engine! On a flat grassy field, a staff member shouted at the ground crew standing on the wing.

In front of him, a 109 fighter that had just been produced and tuned was already preparing to take off. Its oil is purified, and almost half of the parts of its engine are hand-adjusted by engineers.

Thanks to the efforts of the ground crew, the fighter's engine began to spin and made a roaring sound. The propeller turned, and as the speed became faster and faster, it gradually disappeared from view.

"The voice sounds like everything is fine! There is no problem with the operation! The vibration is also within reasonable limits! An inspection engineer loudly reported to the teacher next to him: "It is exactly the same as the data in the laboratory!" ”

"Ground testing is over! Let's take off the experiment! The middle-aged engineer nodded, giving a gesture to take off. Seeing his gesture, the ground crews began to evacuate the plane. The area around the plane, which was originally packed with people, quickly became deserted.

Then the fighter began to slide forward little by little, sliding faster and faster, and in the middle of the runway, the tail landing gear of the aircraft was detached from the ground. Finally, at the end of the lawn, the two main landing gears of the plane were also off the ground, and the whole plane was really flying at this time!

"Beautiful! It's flying! Chris raised his hands like a child in a cheering gesture. Beside him, Desel was also like a child, and he also made a real arm chanting movement.

This is the result of their perseverance together in the last ten days. It gave humans wings, and made the skies of Elanhill more than dragons to fly.

In the "buzzing ......" sky, Orlanke piloted this fighter full of instruments, and he had the most basic memory of how to fly this fighter in his mind. He knew that this was the experience that the Knowledge Orb had brought to him, and it made him very excited.

He did many tests on the ground, including physical fitness and motion sickness resistance. Among the many pilot candidates, he stood out and became the first test pilot to fly a fighter into the air, which is his honor.

When he actually took to the skies, he realized that he seemed to have been born to fly. He shuttled through the air currents that flickered up and down in the sky, and there was no fear at all.

On the contrary, he is now very excited and knows the state of the plane very well. He gently flicked his joystick, and the nimble 109 began to roll agilely, round after round.

The force of the overload pressed on his chest, making him seem to throw all his troubles out of his body. His airplane engine roared through the low altitude, with an exhilarating momentum and stubbornness.

"In a few weeks, we will have dozens of these planes, and in half a year, we may have hundreds of these planes to defend our airspace! Iran Hill is no longer a lamb to be slaughtered, it will stand in the East and become the backbone of the world! Chris spread his arms and shouted loudly into the empty sky in front of him.

He really needs to vent, and he's busy with one thing every day these days. He used his work, with his infinite enthusiasm, with respect and love for mortals, to do something destined to go down in history.

Before Iran Hill, mortals were a bunch of slaves, kneeling and struggling at the bottom of the exploited. And after Iran Hill, mortals flew above the sky, tearing off the shackles of imprisonment and getting a bird's-eye view of the whole world.

Soaring through the sky, Ollank fantasized that he had put on his wings. He felt the clouds playing a beautiful song above his head, and he felt the air around him pounding on his window lattice.

Pulling up his joystick, he piloted the plane up above the clouds, and he heard the roar of the engines regular and steady; Pressing his joystick, he flew the plane into a thunderous swoop, and he felt the wind shudder through the plane.

For a person who has not left the ground a few months ago, any flight, any precious soaring is a pleasure. Ollanke cherishes such an opportunity, and he really wants to fly like this, to the other side of the horizon.

If, if someone deprives him of the right to fly, if someone invades Iran Hill, Orlanke doesn't mind fighting to the end with his life! For the first time, he felt the preciousness of freedom and the meaning of dignity for the first time.

"Test! Test! Spare parts radio communication system test! Can you hear me? Can you hear me? Intermittently, the voice of the commander on the ground came from Orrank's headphones, which made him feel extremely magical.

It is very difficult for people to be able to hear the voices of others in the distance in the sky. In addition to the engine, the most difficult part of this aircraft is the radio communication system.

Now the communication system installed on this plane, there are only three in the entire Iran Hill! One is in the lab, the other two are on the ground, and one is in this plane.

This allows the pilot to maintain good communication and contact with other pilots, and can also receive orders from the ground command in the sky, communication is a very important link, only to ensure efficient communication, in order to develop tactics, to complete the formation, in order to coordinate operations.

However, before that, Alan Hill did not have such a short-distance communication tool. This is also a "sample" that Chris took people to make by hand little by little. It can't be mass-produced yet, but it's already being made.

It's really cool to have drawings and assembly experience. As long as the conditions permit, you can only hard-stack by hand, and you can also make what you want, but unfortunately, if you want mass production, that's another matter.

"I can hear ......" Because he already had a proficient communication equipment instruction manual and demonstration in his mind, Orlanke quickly adjusted the channel and answered the question just now.

Unbeknownst to him, after he had answered, the people on the ground let out another hoarse cheer. Everyone was excited, they hugged each other and cried and laughed, because everything they tested today seemed to have succeeded.

ァ新ヤ~(8)~1~Chinese 網ωωω.χ~8.~1zщ.còм

The radio communication system successfully ensured the contact, and the air performance of the fighter was visible as long as it was not blind. The current Iran Hill seems to be countless times stronger than a month ago. It seems that they no longer have to fear the threat of the dragon, and in the future, they may even threaten the Holy Demon Empire in turn!

At the same time, in the laboratory, a "communication professional" engineer who had been strengthened by the magic ball of knowledge grabbed the earpiece in his hand, and a test sound of "hear or not" came from inside. With a smile on his face, he replied, "I hear you!" ”

The first telephone, which was successfully experimented with in Seris's castle, made Chris's job much easier, just like the radio communication equipment: he could find the person in charge of the project with just a phone call, without having to wait for the attendant to summon him.

And the waiters who waited by his side to run errands now have a new job: His Majesty's secretarial team needs these very capable young people, who are responsible for transcribing many official documents, and are also responsible for receiving and arranging itineraries, etc., and the work has increased instead of decreasing.

At the same moment, when the telephone experiment was successful and an airplane was soaring in the sky, another group of workers and designers in the factory on the ground looked at their treasures and slowly moved.

Iran Hill's first car, or the world's first car, moved in everyone's eyes. After half a year of primitive accumulation and running-in, industrial civilization began to show its huge and awe-inspiring future prospects.

Sophisticated machines began to emerge, and because there was no need for trial and error and no time wasted, the people at Ellen Hill were able to make samples in a matter of weeks for what would have taken decades to perfect. They don't have to face the wrong paths and mistakes, they don't need to improve, they just need to do what is outlined in the magic ball of knowledge.

This car, which was born with a decorated compartment and a complete steering mechanism, is no longer known to be much higher than its predecessor, the ancestor of the car born in Mercedes-Benz. It is almost on the same level as the barrel car, but in terms of workmanship and design, it is much better than the barrel car.

Yes, in another world, this somewhat ugly-looking car has a very loud name.

Chris wanted to come up with a multi-purpose means of transportation, one that could transport the wounded, transport the soldiers, or act as an officer's car. After making a final choice, he chose the Jeep, a classic American means of transportation in World War II.

There are many reasons for choosing it, and after considering it all, Chris decided to mass-produce this car, because it is a more comprehensive off-road car, and the jeep is more comfortable than the German barrel car.

Another reason to laugh and cry is that Chris doesn't want to make his Ellen Hill an otherworldly version of Germany, at least that's what he thinks. So he deliberately avoided the German barrel car, which was also quite good, and chose the American Jeep, which was almost the same.

Exactly two years after Chris's arrival in this world, Ellen Hill had a plane and a car on the same day, and the magic of mortals shone even brighter on this day.

The fourth is more presented.
