Taking advantage of the time when the bald heads went to visit the principal, Ruby had already sneaked into the inside of the airship, perhaps because he didn't expect that there would be people sneaking in from the Rhine Academy of Magic, and they didn't prepare to stay behind, the entire airship was empty, the internal structure was not complicated, but it was somewhat similar to the dormitory, and independent doors could be seen on the left and right of the corridor, but Ruby's purpose was not these rooms, and he touched towards the control room after discerning and putting him down.

I don't know if it's a big heart, they didn't even lock such an important place as the control room, Lubi pushed the metal iron door open with a light push, and what caught his eye was all kinds of neatly arranged strange magic arrays and a large chair more than two meters high, the high back of the chair was enough to reach the ceiling, but Lubi didn't see his feet on the ground under the chair.

"I said it's okay, don't just go into the captain's room!"

A shrill voice from a non-human startled Ruby, and the large chair gradually turned around, and he found a dwarf green-skinned creature sitting on the chair, because it was too short he was almost lying on the chair, this creature could be said to be very ugly from a human point of view, the skin on its forehead was wrinkled together, forming conspicuous furrows, and there were more than a dozen sparse hairs on it.

"Who are you?"

The greenskinned goblin thought it was the damn bald head who had entered his territory again, but seeing that Ruby didn't look like an acquaintance in an airship, he asked with a puzzled look in his little mung bean-like eyes.

"It doesn't matter who I am, I'm interested in this, how did this thing fly?"

Ruby asked, spreading his hands to show that he had no ill intentions, and then stepped on the carpet on the ground.

"Yes, are you also a human being who was shocked by goblin technology, this is the alchemy airship that our goblin clan is proud of, goblin technology, shocking."

The goblin stood up from his chair and said with a happy face, even if the height of the seat was added, it would only make him equal to Lubi's height, and began to talk about some of the basic functions of the airship.

"It's really remarkable in terms of the technology of this world.,Are these magic arrays depicting light and heavy magic?,That's right.,With the help of magic to make matter lose weight and then use propellers to lift off.,But the shortcomings are also obvious.,In mid-air, when the wind is a little stronger, it will be blown away.。

Ruby walked to the magic array and visited, he and Moyuna were pitted by her light and heavy magic when they first met, although they didn't know magic, but this did not prevent him from remembering the appearance of the magic array, after seeing so many layers of light and heavy magic arrays, he also had a good idea of how the airship took off.

"You, you're a goblin?"

The goblin rolled out of his chair in fright at Ruby's remarks, and he stared at Ruby with wide eyes and asked, since the goblins had developed the alchemy airship, no one could see how it worked at a glance.

He even suspected that Ruby was not human, not that humans did not know these magic arrays, but because they could not have such a concept, and this person might be a high-level goblin in human skin.

"I'm human."

Ruby reluctantly explained again that it was very troubling that there were always people who suspected that he was a goblin.

"The windproof barrier is to use it to ward off strong winds in the sky."

The goblin hesitated for a while and told Ruby about the magic structure of the empty boat, how to defend against the air current, but the goblin clan was embarrassed for a long time, and finally made this magic array with the help of a human magician, although the goblin can magic, but not good at it, it can be regarded as a product made by humans together.

"It's really remarkable, I didn't expect the Blackstone Empire to join forces with the goblins."

"The emperor of the Blackstone Empire is more or less a smart person, although it is not as good as the great goblin, this airship is more or less a treasure of the town."

There is pride in the words of the goblin, and the goblin, who is born with insufficient magic power, is destined to not be able to cultivate to the level of free soaring, but can still ascend to the sky with his own wisdom, what a great thing.

"It's not that exaggerated, isn't it hard to make this thing?"

"Difficult? It took 100 years to complete, and it has been made since my grandfather's generation, and time is money my friend. Do you know how much money the Blackstone Empire spends each year to maintain this airship? I won't tell you that you need 10 million gold coins a year! ”

"Is it so expensive? If I come to build it, I can build one with 500,000 gold coins. ”

Hearing this strange price, Lu Bi was also amazed, and this money could buy a 100 million Dharma God girl worth one silver coin. Moreover, in terms of the price of the other world, 500,000 is still high, and if the other world can produce floating gas with a density smaller than air, it can be cheaper.

"Will you make it?"

"Yes, I'll draw a picture for you to see."

Ruby pulled out the pen and paper he had carried with him from his bosom, and in a moment a simple blueprint of an empty ship appeared on the paper.

"It's not magic! There is not a single magic array, what does it rely on to ascend to the heavens. ”

Goblins are clever creatures, and they quickly understood the blueprints drawn by Ruby, but he searched the map without finding a trace of the magic array.

"The airbag is filled with buoyancy gas that is less dense than air, and is lifted into the air by buoyancy."

"Is air dense?"

Goblins also know a few things about density, such as the density of wood and iron, but things like air are still beyond the goblin's knowledge.

"Of course there is, I'll tell you about it."

Ruby felt that he had finally found someone in the other world who had a common language, although the other party was a goblin, and then he explained some scientific principles in detail, and then pulled the topic to another place, and the goblin in front of him was stunned.

Before he knew it, the two of them had been discussing for a day, and the sky outside the window was getting darker, and Ruby was not going to say more, he found that the goblins had a lot of physical knowledge and minds, and if he continued to talk, maybe it would open the door to a new world for them, and in a few hundred years they would be able to make planes and tanks and the like, which was not friendly to the wizarding world.

"Luby, Uncle Luby! Please, let's talk about it. ”

The goblin clung to Ruby's calf and wouldn't let him go, he had never seen a human with such intelligence and talent in his life, and even some of the products that goblins were designing were like prophets in his mouth.

"Let go of me, I'm going back."

"God of technology, you must be the god of technology, follow me back to the goblin tribe, I will let all goblins worship you."

Goblins are different from other races, and they don't have any fixed beliefs, if they have to say it, they believe in the technology they have created, and in the face of his father, who has mastered countless technologies, he is naturally included in the scope of God.

"I appreciate your kindness, but forget it."

Ruby made up for a moment that he shuddered as he sat on the goblin throne and received the scene of a large number of green-skinned creatures kneeling below, it was okay to discuss science, but in his daily life he didn't want to mix with guys with green heads at all.

The goblin reluctantly let go of Ruby's calf and asked him to be a guest of the goblin tribe in the future, and in the end, Ruby also learned that the long-winded goblin was named Sherlock Golinde.
