The length of the airship is nearly 20 meters, the width is about 4 meters, and the hull is wooden, but the color of this wood is much darker than the ordinary wood, showing a dark red, which shows that this airship is not a general tree for building ships.

The ship's mast is so high that it's hard to imagine how such a small boat could use a sail that reaches a height of five meters.

There is a lateral opening in the flanks of the ship, from which a small section of the sailbone peeks, and if there is anything that makes this airship different from other ships, it is probably here.

At this time, the airship was covered with leaves and other covers, and due to its remote location, Ophelia hid it extremely safely.

Amy was the first to let out a cheer when she discovered the airship, and it was because of her familiarity with alchemy that she knew best how precious a ship made entirely of wood was. Walking a few steps to the airship, Amy felt left and right, trying to figure out how this thing was made, and if it wasn't clear that they needed to use this to get there, Amy would even want to take it apart to figure out what was inside.

Seeing Amy's face full of excitement, Ophelia removed the cover from the airship and introduced everyone.

"This is the airship I mentioned earlier, and that's what we're going to need to do to get to church. On the other hand, our destination is not on this continent, but on it, a continent in the sky. ”

"What!"

Ophelia's explanation was clearly unexpected. A city in the sky, that sounds so incredible. Then, as if thinking of something, everyone's attention turned to the airship one after another.

"That's right, the ship is capable of flying. In a moment we will take a real trip to the sky. When he said this, Vader's tone was filled with pride that could not be concealed.

It's no wonder she's like this, the means of transportation on the continent are still on the ground and in the sea, at most they use alchemy to improve their speed and sturdiness, but relying on the ancient technology that remains in religion, they can make ships fly.

As soon as Vader's words fell, Amy immediately noticed the two protruding keels on the side of the hull: "Flying depends on these two things." After speaking, Amy immediately walked curiously towards the side of the boat.

A hint of imperceptible cunning flashed in her eyes, and Ophelia said to Amy, "Okay, Amy, don't look at it yet, I'll let you study it slowly when you get to the place." ”

After finishing speaking, Ophelia looked in the direction of Nia and the others: "But before that, I have to trouble everyone to get this airship outside." ”

Originally, this airship was only placed in the shallow water, and with the combined efforts of everyone, the airship was easily pulled into the sea.

Lowering the plank, everyone boarded the boat one after another.

The ship was empty, and it seemed that the predecessors were not ready to use the ship again. But fortunately, this ship is big enough for everyone, and even if Nia and the five of them are on board, it doesn't occupy much space.

"We're not going far, we'll be there in the evening. And now, ladies and gentlemen, let's go. ”

Seeing that everyone was on board, Ophelia waved her arm forward vigorously, looking a little bit like a captain.

It didn't take long for Nia and the others to reach the surface of the sea, and by this time the sails of the airship had been opened, and the huge four-meter sail looked unusually out of place with the ship.

The waves were separated, and although the airship was on track at this point, it was still only relatively fast.

"When are we going to fly?" Although it didn't take long, Amy was still a little impatient, and at this point she had completely turned on her science madness mode.

"That's going to be good, and we'll be able to start when it's a little bit faster." Ophelia, who was in the bow of the boat, turned around and comforted Amy before turning around. After all, the airship is different from ordinary ships, and the control here is not as simple as that of ordinary fishing boats, and Ophelia, who is in charge of operation, must accurately grasp the movement of the boat.

After about four or five minutes, the speed of the airship was already beyond the speed of a normal ship, and Ophelia also shouted to several people on the board at this time: "The speed of the airship is enough, we will start flying soon, everyone pay attention." ”

Although the place where Nia and the others were sitting was not far from her, Ophelia had to raise her voice because as the speed of the airship began to increase and the wind began to appear in everyone's ears.

Hearing Ophelia's prompt, Nia and her group, who were originally sitting idly on the boat, immediately cheered up.

With a greeting behind her, Ophelia immediately began her next move.

Quickly turn both small knobs to the fullest, then press firmly down one of the levers below, facing back. And with Ophelia's movements, the hull of the airship also changed rapidly.

On both sides, the planks on the front and rear sides of the protruding keel gradually opened up to create a long and narrow space. The next moment, the keel of the ship, which was only about half a meter exposed, suddenly popped open to the size of four or five meters, and the keel was wrapped with a layer of film, as if it had turned into wings.

These wings also seem to have the effect of increasing the speed of the boat. With the ejection of the 'wings', the speed of the airship was increased again. Moreover, Nia and her party could clearly feel that the hull of the ship was gradually leaving the water.

"It's amazing, I didn't expect that without using magic amplification, it can be achieved to this level purely by machinery, how did Ophelia do this?" Watching the hull of the ship begin to rise into the air, Amy asked Ophelia, who was operating the ship, with excitement in her eyes.

Because relying on magic can easily amplify and transform machinery, the effectiveness of alchemy machinery is far beyond the level of ordinary pure machinery, which makes almost everyone on the continent form the idea that only magic can make large machinery.

Because this kind of thinking binds most people, it is extremely difficult for the development of pure machinery manufacturing on the mainland, and the development of alchemy machinery is also stuck at a rather embarrassing level. It can be said that the take-off of the airship at this time opened a door for Amy that had been sealed by people for a long time.

"You see that the shape of the upper and lower sides of the airship is different, and in the same amount of time, the air on the upper side of the wing flows more distance than the air on the lower side, that is, the air on the upper side of the wing flows faster than the air on the lower side. Therefore, when the airship slides, the air pressure on the upper side of the wing is less than that on the lower side, which gives the airship an upward buoyancy force. When the speed of the airship reaches a certain level, this buoyancy reaches a force strong enough to make the airship fly. And so, it flew. ”

Because he hadn't delved into this aspect, Ophelia didn't know the answer, and for Ophelia and Vader, the question was even more difficult. But to everyone's surprise, Nia, who was sitting on the side, suddenly spoke up and said the reason.
