Although the airbag made of camel leather is very strong and difficult to cut with a knife, they have put all their energy and savings into this flight experiment and will not allow any mistakes.
"Uncle Darren, how did you pull such a big thing over here? It's called an airship, can it really fly?" The leading boy was not afraid of Darren, who was not as tall as him, and asked with a smile.
The crowd watching was also extremely curious. Judging from its appearance, this thing called an airship must weigh tens of thousands of pounds, but Lydia and others were able to move it all the way from the workshop on the west side to the square.
"You don't understand this. This thing only looks big, but it's actually not heavy at all... No, that's not right. It should be said that it's not heavy when pushed. I heard from the wizard that this is because the lift offsets most of the gravity, plus the pulley at the bottom, so it's not tiring to carry it..."
Darren spoke proudly, his beard sticking up, but before he could finish, Lydia stepped heavily on him. Only then did he react and immediately changed his expression. He stared at everyone present as if he was guarding against thieves, and spoke with a serious expression.
"Confidential, this is all confidential!"
Chapter 72 This is definitely a scene in the history of magic that deserves to be remembered forever!
Darren's words made the townspeople present feel itchy, but there was nothing they could do. They could only speculate whether this airship could fly, how long it could fly, and whether it would fall to the ground before reaching a high altitude like the previous aircraft...
At this moment, the professors and students of Yieta College were gathered in the center of the square, staring at the huge airship parked in the center of the square.
Even Hellram couldn't help but be amazed at its size. After a pause, he turned his head to look at Lin En and said, "What a delicate alchemical creation. I heard that this is your work, Professor Lin En?"
Lin En explained with a smile. "I only provided a blueprint. The production process of the airship was completed by Lydia and the others. It should be said that this airship was made by us together."
Although Lin En said this, Helram and others knew that production was secondary. For any alchemical creation, its design principle was the most important!
"Professor Lin, since you call this thing an airship, you are not really planning to make it fly? How much magic power will it consume?" Kevin asked curiously.
The bigger and heavier something is, the harder it is to fly into the sky. This can almost be said to be an iron rule. To send such a huge alchemical instrument into the sky, the amount of magic power consumed is probably incalculable.
"I think you're mistaken. It's not magic that can make this thing fly!" Lin En shook his head.
It's not magic? Upon hearing this, the professors and students present were stunned. Could it be that this thing could fly by itself?
"Is this the aircraft you mentioned last time, changing its power and redesigning its structure?" Hellram immediately thought of what Lin En said when he just crossed the sea to the land of wizards. He indeed did not feel any magical fluctuations on the airship.
"No, if you must say, this airship uses another way of flying." Lin En thought for a moment and answered.
Hellram frowned, wondering what the so-called other way meant, and then asked with interest.
"Then how long do you think it can stay in the sky at most? Ten minutes? An hour?"
“I think it’s going to be longer than any number you can imagine. How long it can fly depends solely on how long Lydia wants to stay in the sky…” Lynn replied with a smile.
Phillip and others immediately lost their composure after hearing this. Doesn't this mean that if Lydia doesn't want to come down, she can keep flying in the sky?
This doesn't make sense, considering that flying is a feat that only a handful of wizards can achieve...
But before anyone could say anything in response, a voice rang out from behind.
"You mean this airship can stay in the air continuously without consuming any energy? This is impossible and totally inconsistent with the law of conservation of magic!"
Lynn looked back in surprise, and then saw two wizards in gorgeous clothes walking towards them.
"This is Mr. Tik, a member of the Wizard Council..." Philip hurriedly introduced him to Lin En, with a bit more respect in his tone. Although Tik was a three-ring wizard like him, his alchemy level was very high, and his status in the wizard land was not much lower than that of an ordinary great wizard.
"As for the other one..." Philip looked hesitant.
"My name is Luo Er! I'm a specialist sent by Magic Weekly." Luo Er replied politely.
"Hello, Mr. Tik, Mr. Roll." Lin En nodded. He was surprisingly familiar with the name Tik. A first-level magic he had learned was called [Tik's Farsightedness]!
"Stop being so polite. You haven't answered my question yet..." Tik had no intention of chatting and asked eagerly.
"If it's just about floating, then of course there's no need to consume extra energy." Lin En explained, and then continued. "As for the principle, I can only say..."
“This is a trade secret!”
The expression on Tik's face froze immediately, and then turned into a helpless look. As an alchemist, he certainly knew that there were some things he shouldn't ask.
"Professor Lin, the inspection has been completed. The Overlook can take off at any time!" Lydia trotted over, made a military salute, and said loudly.
"Then we can start now!" Lynn said, waving his hand.
Having received approval, Lydia immediately and excitedly called Darren and others, and began to fill hydrogen into the airship's auxiliary airbags, and put a sturdy rope around several pillars in the square to prevent it from flying away prematurely.
The airbag above the airship looks like a whole, but in fact it is divided into two airbags, the main and the secondary.
Only when the main airbag is filled with hydrogen, the lift exerted on the airship is slightly smaller than the gravity, which is at a critical point. Therefore, as long as the auxiliary airbag is also filled with hydrogen, it can fly directly.
When landing, you need to do the opposite, open the auxiliary airbags to allow air to flow in, and the airship will slowly fall.
As for why hydrogen is used instead of the safer helium, it is of course because the former is easier to obtain and can be separated directly from water.
The thing that Yieta Harbor has the most is water!
While Darren and others were filling the auxiliary airbags with gas, Lydia had already climbed up the ladder into the cabin of the airship, pulled the alchemical eyepiece on her head, and placed her hands on the large steering wheel, looking like a captain with unstoppable excitement on her face.
Everyone in the square focused their attention on it. As the hydrogen in the auxiliary airbag increased, the huge airship began to shake slowly and floated up little by little.
"Great, it really can fly!" "Really, our efforts have not been in vain..."
Seeing this scene, several halflings hugged each other excitedly. They had been working day and night for the past half month just for this day!
"Overlook, take off!" Lydia swung her knife and cut the rope connecting the airship to the pillar, shouting loudly.
Under the excited or shocked gazes of countless people, the huge monster in front of them quickly broke free from the constraints of gravity and flew straight into the sky!
"Amazing!" Helram said with emotion as he stared at the airship floating farther and farther away in the sky.
Roll on the side quickly took out a feather pen, used magic power as ink, and quickly drew down everything he saw.
This is definitely a scene in the history of magic that deserves to be remembered forever!
A halfling who doesn't know any magic flew into the sky on a huge airship that is taller than two stories!
Chapter 73 Touching the clouds in the sky!
"It's unbelievable, this thing actually flies!"
If the sight of the airship taking off into the sky was extremely surprising to the wizard, then it was a shock to the townspeople who were watching!
Because everyone knew Lydia, a halfling who was usually noisy and always liked to tinker with strange things.
The most important thing is that she, like all the ordinary townspeople present, does not know any magic.
And now, Lydia was right in front of them, driving something bigger than a house, flying straight into the sky, doing something that even many wizards could not do!
"Dad, can I fly to the sky in the future?" The boy who had just climbed up the sculpture to touch the airship looked at the man in the gray robe and asked excitedly.
"What are you thinking about? I'm sure some wizard has secretly cast a spell on the airship..." The man in gray robe didn't believe that a halfling could fly by his own strength. In the land of wizards, all miracles are the power of magic.
"Who said it was magic?" Darren was immediately unhappy when he heard this, and corrected him angrily. "I guarantee that every part of this airship was made by us halflings, without using a single bit of magic!"
"When Lydia comes down from the sky, you can also go to the airship to take a look..."
"As long as you pay ten silver coins, anyone can take a ride on an airship for a spin in the sky. I heard from Lord Lin that this thing can fly very high, even higher than many clouds. If you have the chance, you might even be able to touch the clouds in the sky." Darren said complacently.
Can you fly higher than the clouds?
The children in the square couldn't help but look up at the sky, watching the huge airship getting farther and farther away from them, and imagining what it would feel like to touch the clouds. It was so white and must be as soft as sheep's wool, right?
The other townspeople were also somewhat tempted. Such a huge alchemy machine must be very expensive. It only costs ten silver coins to fly up to the sky for a tour. It doesn't seem too expensive...
You know, that’s the sky!
At the same time, hundreds of meters above the sky, Lydia was standing on a special chair, looking down, watching the dense crowd in the square getting farther and farther away from her, turning into small dots, and finally the whole picture of the port city appeared in front of her.
Everything seemed so small, just like the wooden models she kept in the workshop, as if they could be crushed with one foot.
"Is this what it feels like to fly into the sky? It's so awesome!" Lydia looked around, then excitedly gazed at the distant mountains and the vast sea.
Although she had taken to the sky in a simple aircraft more than ten days ago, the height was only a few dozen meters, and she did not dare to be distracted at all.
It's not like now, there is no need for her to control it, the airship can float in the air spontaneously, and she can do whatever she wants here.
Suddenly, a strong wind blew, and the originally stable airship began to sway slightly in the wind.
People who fly into the sky for the first time often feel an inexplicable fear in their hearts, but Lydia was not afraid at all. Instead, she bravely climbed to the edge of the airship, spread her arms, faced the strong wind, and screamed to vent her excitement.
It was not until she saw a white cloud floating not far from the airship that Lydia had a bold idea in her mind. She jumped down and sat back in her seat, holding the rudder and driving the airship directly towards the cloud!
The huge airship crashed head-on into the cloud and passed through it. Lydia's eyes were covered with white, and her cheeks and arms were wet. It felt like she was standing on the beach and being blown by the melodious sea breeze.
"This must be a happy cloud!" Lydia said with a smile.
However, while playing, the half-orc girl did not forget the task Lin En assigned to her. After driving the airship around for a while, she hovered above the square again and then pulled the wrench next to her.
The wooden board at the bottom of the airship immediately popped open, and two spheres with a mass difference of dozens of times fell from the cabin. However, due to the restraint of the ropes, they remained suspended in the air, swaying constantly from side to side, pulling the airship to tilt slightly.
Then the half-orc girl pulled the alchemical eyepiece in front of her eyes, stuck her head out and waited for Lin En's gestures and orders.
This eyepiece is the only magical item she carries. It has a long-sightedness magic that makes her vision as sharp as a griffin. She can clearly see Professor Lin in the crowd even at a distance of two kilometers.
……
"It looks like the next issue of Magic Weekly will be a big seller!"
Ten minutes ago, Roll, who was in the square, drew the illustration with great satisfaction, and added his own feelings at the bottom. He already had a rough estimate of the sales of the newspaper in his mind.
Lynn leaned in to take a closer look. There were three pictures drawn on the papyrus, showing Lydia boarding the airship, cutting the rope, and flying into the sky.
Although time was limited and only a few outlines were sketched, the picture was already lifelike. The sketching technique was no different from that of a human printer. No wonder the other party could become a specialist of "Magic Weekly".
After such a delay, the airship had already flown high into the sky and looked like a small dot from this side.
"This is too high!" Theodore looked up in amazement at the airship that was still climbing into the sky. At first he thought that even if this thing could fly, it would only be a few hundred meters high at most. He didn't expect that in just a short while, the airship's height had exceeded two thousand meters.
Fortunately, the practice of farsightedness magic is not difficult, and most of the wizards present know it, so they can still see clearly even from such a long distance.
The airship stopped after rising to an altitude of 2,500 meters, and then used the thrust of steam to drive the propeller at the rear of the cabin and slowly moved forward.
Not only can it fly, but it can also drive, and it drives very steadily!
"This height is probably beyond the attack range of most magic." Tik looked at the floating airship from afar, his expression becoming a little solemn.
In a sense, this thing is a weapon of war. With two magic crystal cannons hung on it, it can carry out long-range attacks.
If twenty airships equipped with magic crystal cannons launched an air raid on the port of Yieta, without the intervention of the great wizard Hellram, the entire city would undoubtedly be reduced to ruins.
"What an ingenious design, perfect and terrifying..." Hellram was also very aware of this. He turned his head and glanced at Lin En, and asked again. "The design of this airship should not have been completed recently, right?"
If the crude flying vehicle made by Lydia half a month ago could be seen at a glance as a crudely made prototype, then this airship now is a finished product.
