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?
"Could this be 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.
Philip and the others immediately became upset after hearing this. Doesn't this mean that if Lydia doesn't want to come down, she can keep flying in the sky? This is unreasonable. You know, flying is a feat that only a few wizards can do...
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.
"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 to cut the rope connecting the airship to the pillar and shouted loudly.
Amid the excited and shocked gazes of countless people, the huge object in front of them quickly broke free from the constraints of gravity and flew straight into the sky! "Amazing!" Hellram said with emotion as he stared at the airship that was drifting farther and farther 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 does not know any magic, rides a huge airship that is taller than a two-story building and flies into the sky! (End of this chapter)
