I picked up the dragon girl at the beginning and I used artillery fire to liberate the other world

"Teacher, can this iron thing really fly?"

In a hidden three-story building in the northeast corner of the Mithril City, seven or eight students were gathered together, looking at the blueprint in the hands of their teacher Walder.

A strange thing was drawn on a thick stack of drawings.

That's right, they couldn't figure out what the thing on the blueprint should be called, so they had to call it something.

At this time, their teacher Wald fell silent for a moment. Can this thing called a fighter really fly?

"Do you remember what I taught you?" Although Walder's mind was also full of question marks, as a teacher, he still had to maintain his dignity in the hearts of his students.

"Practice is the only way to test truth, and according to the laws of mechanics, as long as the lift is greater than the gravity, it can rise even without wings."

Before Wald could finish speaking, his student Ian hurriedly took out a piece of rough paper, put it in his hand and started writing.

As Ian wrote, his eyes gradually became more and more excited.

"Yes, as long as there is enough lift, no matter how heavy it is, we can send it into the sky!"

"Ian, you are too happy too soon. Strength does not come out of thin air."

Another student, Alex, frowned slightly. He still found it hard to believe His Majesty Bai Yan's idea.

"This is the genius of His Majesty. Has everyone forgotten it?" Ian's face was flushed with excitement. He held up the paper in his hand and excitedly showed it to everyone.

"Air pressure!" Ian yelled, scaring everyone.

"We can use the atmospheric pressure to send the iron lump that Your Majesty wants into the sky!

Look at the principle note below the diagram, the faster the speed, the lower the air pressure.”

Ian took the drawing from Walder's hand, then quickly spread it and a new piece of rough paper on the desk not far away.

"Look at your majesty's brilliant idea. Just give this iron lump a pair of wings, a pair of flat wings at the bottom and convex at the top. In this way, when the speed is fast enough, the gas above will travel a longer distance and the relative speed will be faster.

In that case... "

Before Ian finished speaking, everyone understood.

"Your Majesty, how did he come up with this idea?"

"God of Wisdom, His Majesty Bai Yan must be the God of Wisdom!"

“This is such a bold and scientific design!”

A group of young people gathered around Wald and discussed the drawings until late at night with no signs of stopping.

"The fuselage must be smooth so that the impact on airflow is minimal and the most stable."

"There are also many things to pay attention to when manufacturing piston engines, and multiple tests must be performed before forming a production line."

"And the landing gear needs to be made of lightweight, pressure-resistant alloy."

. . .

A group of people discussed these drawings for a week before starting to manufacture the first La-7 fighter.

To this end, Wald summoned the country's top engineers and launched a bidding process for factories across the country. A beast belonging to space is being conceived.

On the other side, Electra couldn't help but find Bai Yan for the fifth time.

On the top terrace of the palace, Bai Yan was lying on a lounge chair enjoying the pleasant breeze.

On the side, Annabelle and her sister were serving on both sides of Bai Yan, one of them was rubbing Bai Yan's shoulders, and the other was putting a few small fruits into Bai Yan's mouth from time to time.

However, there was a hint of reluctance on Agatha's face. She was dragged here by her elder sister.

She felt helpless about the fact that her elder sister had become Bai Yan's bootlicker, but there was nothing she could do.

Seeing Annabelle smiling, Agatha wanted to go up and slap her hard to wake her up.

Where is the look of a legendary strong man?

"Your Majesty Bai Yan is really still uncomfortable~"

The great mentor appeared on the terrace, and seeing Bai Yan enjoying himself with a cold face, he finally couldn't help but grit his teeth and reveal a bit of anger.

"I've fought so many battles, can't I enjoy myself?" Bai Yan glanced at Electra with a funny tone.

"Yes, the master is usually very tired." Annabell looked at the silver-haired woman in front of her and showed some dissatisfaction.

Hearing this, Electra became even more annoyed, "Are you two still from the Garden of the Gods?

I am the Grand Master of the Silver Moon Empire, the Envoy of the Court of the Gods, and even Gaia doesn't dare to act presumptuously in front of me."

"Garden of the Gods? I haven't been a job for a long time. I am the master's little slave girl, and I only listen to the master." Annabelle's face was shy, and she looked at Bai Yan with uneasiness.

After seeing a smile on his face, he immediately shouted that his heart felt like it was hit and he was extremely excited.

Master, does he like to hear me say such ambiguous words?

Annabell felt like her brain was broken for a moment, and she stood there with her head slightly lowered, feeling uneasy.

Seeing a good follower of God, a strong man with legendary strength become like this, Electra couldn't help but sigh.

We have to keep Hellia and Xiao Meng away from this guy from now on.

"It's been half a month. When are you going to send envoys to the Silver Moon Empire?" The Grand Master never forgot the purpose of his trip from beginning to end. The war has really become tense.

"Let's get ready and set off today!" Bai Yan looked at Electra and nodded slowly after a moment.

"Who's going?"

"me!"

Hearing this, the Grand Master showed a hint of surprise in his eyes, "You're going?"

"That's right, let's get ready and go."

Bai Yan stood up and turned to look at Annabelle and Agatha, smiling and nodding, "Thank you for your hard work."

"No, it's okay." Agatha looked surprised and lowered her head embarrassedly.

"Master? Can you take me with you?" Although Annabelle knew she shouldn't ask this, she couldn't help but ask.

After all, as a legendary wizard, she could still be of some use, right?

"Go if you want to." Bai Yan ruffled Annabelle's brown hair, then looked at Electra, "Okay? Miss Electra?"

"Of course, but are you really not afraid that I will imprison you?" The Grand Master was a little shocked. How could a king go to another country in person?

"If that happens, my army will probably flatten the Silver Moon Empire." Bai Yan said, turning around and walking downstairs.

Looking at Bai Yan's back, Electra had a slight smile on his face.

He must have trust in me to go to the Silver Moon Empire in person. As for the last sentence, it was just a joke.

The Aksashi Empire was originally the weakest of the four empires, not to mention the Baiyan Empire which had experienced a civil war.

Flatten the Silver Moon Empire? That's so domineering that it's a little cute.

This man is obviously a tsundere.
