After trying to prove that he was physically strong, mentally healthy, and had a normal orientation, Sekiya was fortunate enough to go out of the cabin and witness this legendary submarine that seemed ordinary and magical from the perspective of a futuristic person. I have to admit that this is simply a work of art! It is no wonder that the professor listed it as the crystallization of the strongest industrial technology in modern times, along with the Xuanzi-class airship of the Taiping Heavenly Kingdom that occupied southern China!

You must know that the reason why the Taiping Army was able to subdue the Qing State, which was supported by Britain, France, Japan, Italy, Germany and other eight countries, and abolished the unequal treaties in the territory, was due to the strong ships and cannons from the sky!

Guan Gu is not clear about the parameters of the zeppelin pirated by a copycat expert like Lu Xiaobu, but listening to the professor's meaning, it is quite powerful. Just look at the Nautilus.

The shape of this legendary dive boat is a long cylindrical shape with conical ends, much like a cigar.

The length of the cylinder, from beginning to end, is exactly seventy meters, and its transverse beam, at its widest point, is eight meters. Therefore, the structure of this ship is completely different from that of ordinary long-distance steamboats, its width is one-tenth of its length, it is long enough from end to end, and the bottom of the two waists is quite round, so that the water is easy to drain away when the ship is moving, and it will not hinder its navigation in the slightest.

The total area is 1,011 square meters and 45 centimeters, and the total volume is 1,502.2 cubic meters. That is, - when the ship is completely sunk in water, its displacement or weight is fifteen hundred cubic meters or one thousand fifteen hundred tons.

Although Captain Nemo had explained to the professor and his party the T-shaped support structure inside the outer deck, Sekiya still didn't think that this design alone would be enough to withstand the intense pressure of ordinary ship steel hundreds of meters deep in the sea! Even in the middle of the twentieth century, when submarine technology was more mature, the interior of the submarine was extremely narrow in order to better resist water pressure and reduce its size. It was only in the 21st century, with the advancement of materials science, that an underwater villa like the Sakura had enough space for people to enjoy. What's more, the Little Sakura used the power of the dragon clan's alchemy to reach the level that Guan Gu saw at that time.

The Nautilus is rich in space in every cabin. Captain Nemo even creates a museum-like living room in a submarine where every inch of land is at stake! This living room is a large rectangular room, ten meters long, six meters wide, and five meters high! With such a large room in the middle of the ship, how much space is left for keels, wiring, and aisles? If it is a general marine steel, this kind of design, maybe one day the hull will break from the weak point where the living room is located into two sessions! The materials for shipbuilding must not be ordinary!

At least Guan Tani, who walked around the corridor, could confirm that these metals would never be steel or ordinary alloys that could be mass-produced in the 19th century, and that every inch of the floor's materials would be the best materials that could be refined to make the boy Kiriaoka!

While thinking about it, Guan Gu had already walked into Captain Nemo's luxurious living room. The crew members along the way smiled at him at most, and would never say a word to him.

The ceiling of this living room is decorated with a faint pattern, and the lamp balls attached to it emit a bright and soft light, illuminating the treasures displayed in the museum. This living room is a museum! Captain Nemo, with his own ingenuity, brought together all the curiosities of nature and art, giving it the artistic messiness characteristic of a painter's studio.

There is also a library at the back of the living room. On the four walls of the library are tall rosewood shelves inlaid with copper wire, and the shelves are lined with uniformly decorated books. Beneath the shelves lay rows of couches covered in maroon skins; The couch is just the right curvature and comfortable to sit on. Next to the sofa, there is a lightweight movable bookcase that can be moved around at will, so you can put a book on it and read. In the center of the library was a large table filled with pamphlets, some of which were outdated newspapers. Four frosted glass spheres half-embedded in the vaulted ceiling emit a soft electric glow, bathing the harmonious whole. I looked at the library and admired it so much that I could hardly believe my eyes.

Sekiya watched the vibrant 19th-century Haitian world through the large glass windows embedded in the living room wall in amazement, while carefully studying the various textures of the metal faults that reveal through the window frames. Using his spiritual sense, Guan Gu could see that the molecular composition of this material was extremely stable, and it was definitely an unknown elemental metal!

"It's incredible! People in the nineteenth century could have built submarines! This is simply black technology! The speed is still so ......," Guan Gu muttered quietly.

"It's that fast, isn't it? Yes, I think it's weird too. According to Captain Nemo, the Nautilus relies on coal-fired batteries to charge its sodium batteries to provide energy for its operation. I don't believe that Nemo's steam engine is so powerful, and the battery energy storage capacity will be so powerful! There must be something we don't know. The professor's voice suddenly sounded from behind Guan Gu.

"Mr. Professor?" Sekiya turned around in astonishment, and found Mr. Professor on a chestnut fur sofa in the corner, looking at a drawing. Earlier, Sekiya had seen this drawing that Mr. Professor had kept close to him, which was the construction diagram of the Nautilus drawn by Mr. Professor based on his own exploration.

"Mr. Professor, I really can't believe that a ship as huge as the Nautilus could travel thousands of nautical miles using such an unstable energy source as sodium batteries alone! Sodium is so unsafe, it's not scientific sense! Sekiya looked like a curious student and asked Mr. Professor with his doubts.

"Energy! It is the key to the progress and development of science and technology, my dear Consel. We have gone from manpower to animal power, from animal power to water power, to the steam engine, and we have come to know that we have not yet been able to make full use of electricity like Captain Nemo, and with the development of energy, some things that we could not have imagined before have become a reality! Every energy advancement has also brought the developing world to an inflection point! ”

"The steam engine has brought us European countries a leading position in the world for nearly half a century. But as I told you, since the invention of the oil-burning internal combustion engine, as well as the industrial equipment and war weapons airships and steel warships that were driven by those masters of the Taiping Heavenly Kingdom in the East, there is no doubt that a new historical turning point has come. The biologist was talking about something that didn't fit his profession, but it didn't seem to affect the interest and depth of what he was saying.

"But even the Orientals didn't build such a submarine, did they?" Sekiya asked tentatively. If Lu Xiaobu had copied such a thing as a submarine, the knowledgeable Mr. Professor and the Netherlands would not have felt so incredible about the Nautilus.

"That's true. Therefore, Captain Nemo's technology not only surpassed most European countries, but also was unique compared to the Taiping Heavenly Kingdom with the Prophet! Still, Conseil, we have to find a way to escape from this ship......" Mr. Professor was silent for a moment, and quietly sketched the remaining half of the unfinished sentence in Guan Gu's palm: "And get its technology!" For the survival of France! ”

No wonder you are not in a hurry to escape, Professor, the picture is not small! If you succeed, if Louis XIV is still in power, he will not be able to make you a count?

"Can you tell me about the Taiping Heavenly Kingdom in the East? What kind of existence was their prophet? Guan Gu understood that most of the prophets were Rong Hong, who was dominated by Lu Xiaobu's soul, and the opportunity to learn more about his cheap "Lao Tzu" was really not to be missed.

"Prophet,......" was before the professor could speak, when a rhythmic sound of footsteps sounded at the entrance to the drawing-room, and a magnetic voice came: "My friend, you ought to have seen the submarine volcanoes we have just passed!" My lookout swore to me that he had seen a four-legged reptile the size of an adult blue whale entrenched there! What were you guys just discussing? A prophet of China? That's a great character! I can still have a few ships like the Nautilus at most. He can beat me in the ocean whenever he wants...... That's truly an admirable existence! ”

What do you mean? How many more ships like the Nautilus can there be? Are there any key materials that are so limited? Captain Nemo, you're the one who owns the entire Earth's oceans!
