"What a wonderful duel," Sylvie couldn't help but exclaim.

"Indeed." Tilly raised the corners of her mouth, glancing at the head butler with a teasing look—even Camilla, who was usually so nonchalant, had been completely engrossed at the last moment, her eyes following the two entangled biplanes without wavering.

When Aircraft No. 2 broke free from the tail chase by using the wind, the ending was already determined.

But at this point, the victory or defeat was no longer important.

She saw what she wanted to see.

For example, in a many-on-one situation, the side with numerical superiority had a great advantage. They could more easily allocate altitude and speed until they forced their opponent into a desperate situation.

But this number didn't simply refer to the sum of the forces each side deployed. Extrapolating further, one could know that even the side that was at an overall disadvantage could gain opportunities for a many-on-one situation in certain areas through maneuverability and changing formations.

If the targets were more agile Terror Beasts, coordinated combat would undoubtedly be even more important.

She also noticed that the side at a higher altitude during combat had a better chance of winning. If they could drag the enemy into a dogfight and then launch an ambush from a squadron lurking in the high sky, it might be the most ideal opening.

As for how many people were suitable to form a team, and how to change formations when engaging at close range, that would be what she would study next.

However, Tilly also knew that this training was still based on the experience of biplane combat. If she truly wanted to finalize the next part of the "Flight Manual," she would have to test it out on the actual battlefield.

What pleased her was that the growth rate of this batch of students was even better than expected. At this rate, when the "Skyfire" was officially in production, the aerial knights would be able to try their hand in Wolfheart and Everwinter.

Of course, she wouldn't be absent from this war of revenge.

The Unicorn was only meant to be a trainer. The brand new aircraft that her brother had promised should already be in production, right?

After the training session, she might as well go to the castle to remind him to hurry up.

The last aircraft also landed steadily at the airport at this time.

Whether it was the student team or the trainee square, enthusiastic applause erupted.

"Now I know why you divided them into two such distinct camps," Sylvie sighed softly.

"Although that was indeed the intention, I didn't expect the effect to be so good. I originally thought it would take at least ten days to half a month to see this scene." Tilly smiled, waved to Hawk Face, and handed him a new list, "Now that they're all back, let the next round of students prepare."

Wait for me a little longer... she looked north, I will soon make the demons pay their blood debt.

"Woo————————————"

A long horn sounded outside the porthole, indicating that there were ships ahead. Since entering Graycastle territory, similar sounds had become frequent. Manfred could hear it about every half hour. And now, the interval had shrunk to about a quarter of an hour, or even less.

He had never heard that Graycastle was a country with developed navigation.

In the general impression of the Wolfheart nobles, although this kingdom was large, it was not rich in resources, probably about the same as Wolfheart. In terms of wealth, Dawn was the most enviable.

But now it seemed that this was not the case.

But thinking about it, it was normal. News could differ greatly from one village to another, let alone across two kingdoms. After all, they had defeated the Church, and that alone was enough to prove that their king's methods were extraordinary.

He just didn't know how long it would take to reach the legendary Neverwinter City.

Manfred thought to himself, yawning slightly from boredom.

The long sea journey was easier than he had imagined—after the ship arrived at the northern port of Dawn, it didn't rush to the next port, but sorted out the crowded cabins. People with severe seasickness were rerouted by land, and the rest were given ample time to rest. The Dawn people even built a large number of temporary residences in the dock area, looking fully prepared, and their cooperation with Graycastle was seamless. If it weren't for the flags flying on the walls, he would almost have thought this was the territory of the King of Graycastle.

Obviously, in order to transfer them, the two countries had reached some kind of agreement... he didn't know how much Roland Wimbledon had paid.

Thanks to this measure, the bruises on his body healed quickly, almost completely recovering in a week. He hadn't used the miraculous pills that the two women had given him.

He wondered how they were doing... Manfred touched the pills wrapped in his arms, and the figures of the two women involuntarily appeared in his mind. Although they were quite haggard at the time, and their bodies were dirty, he could still catch a glimpse of brightness from their dry hair. If they were taken care of a little, they shouldn't be too bad.

He hoped they could arrive safely, he thought. If they could escape their slave status, they could probably sever their dark past and usher in a new life.

Suddenly, Manfred heard a strange buzzing sound, as if something was passing overhead.

Then, there was a sound of chaotic footsteps coming from the cabin above.

"So noisy..."

"What are those guys doing? Can't a person even sleep properly?"

People around him immediately complained.

Manfred's heart stirred. He rolled over and climbed down from the bunk, peering out of the porthole.

If he heard correctly, the direction of those people's footsteps was basically the same as the buzzing sound.

Outside was still the blue sky and the boundless sea, seemingly unchanged, except for a few large birds chasing and playing...

Wait, what kind of birds are those?

Manfred rubbed his eyes, almost unable to believe what he was seeing—when the "birds" were perpendicular to the sea, the angular and straight wings and tail didn't look like normal creatures at all!

When they flew over the ship again, he confirmed that he wasn't hallucinating from being cooped up for too long. That thing wasn't a living thing, but seemed to be made of metal. Even more incredible, he even vaguely saw people sitting inside!

Manfred opened his mouth, wanting to shout, but couldn't utter half a word. How could this happen? Even though he had gradually accepted the existence of the First Army and steamships, and had a certain expectation for the prosperity of the Graycastle capital, this scene still greatly exceeded his understanding.

They were both kingdoms, but he felt that Graycastle and Wolfheart were not even in the same world... No, not just Wolfheart, it was probably also completely different from Everwinter and Dawn, otherwise he wouldn't have heard any rumors about it before.

Since when had other kingdoms been left so far behind?

Just as Manfred's thoughts were in chaos, the ship sounded its horn again, but this time the sound was much longer, usually to remind the migrants that they were about to dock.

Neverwinter City, here we come.
