Chapter 509: The Flea Carriage

As a traverser, Ricky knew that airships were no surprise, but 'knowing' and 'making them' were two completely different concepts!

The flight principle of the airship is not complicated, it is nothing more than rushing into the airbag a gas with a density lower than the air, such as hydrogen or helium, and then making the airship generate upward buoyancy, which is similar to the principle of a hot air balloon. Of course, compared with hot air balloons, airships undoubtedly have more advantages, and hot air balloons are far from being comparable to hot air balloons in terms of endurance! In addition, the military airships of the earth's modern design are also equipped with auxiliary airbags that can control the shape and buoyancy of the airship by inflating and deflating, and rudders and elevators that can improve the power of the airship, and so on.

However, for Lucky, who is now in the magical plane, there are many difficulties to overcome in order to truly build an airship!

The first is the source of gas used to inflate the airbags. For gases with a lower density than air, the common options are none other than hydrogen and helium. In exchange for the earth, helium is more chosen for the gas inflated by airships, and helium is produced in large quantities, that is, the method of industrial production of ammonia, which is nothing more than "natural gas separation", "purification of synthetic ammonia tail gas", "uranium ore method" and other methods. Unfortunately, in any of these ways, Leitch is not equipped to make it happen!

Then the remaining option is hydrogen. There are many methods for industrial hydrogen production, such as 'hydrocarbon cracking', 'hydrocarbon steam reforming', etc., and of course, these methods are also meaningless to Leitch. But there's another method that is so common for making hydrogen in large quantities in industry and that works for Reich as well: electrolysis!

The so-called electrolysis method is actually to inject a high-voltage electric current into the salt water, and finally decompose the water molecules into hydrogen and oxygen! As for why it is salt water, it is because pure water is not conductive!

In some fight scenes, once a person with water ability meets someone with an electric ability, he will often be suppressed, after all, water can conduct electricity! Because the essence of magic is to use the elements that exist in space, the water magic is the water element, and of course the water is pure water!

Therefore, among the mages who were responsible for making hydrogen specially arranged by Rych, one of them was responsible for pouring salt into the pool from time to time. This move made these mages with the level of an arcane master secretly surprised, but they also knew that now was not the time to study these.

Now that the method of making hydrogen has been determined, it is not surprising why Ricky would assign 'Water Arcanist + Summoning Arcanist' or 'Water Arcanist + Thunder Arcanist' to each pool, which is nothing more than one responsible for providing water and the other responsible for discharging!

As for how to separate the hydrogen and oxygen produced by the electrolysis of water (after all, oxygen is not needed), this is not a problem, in the process of electrolysis of water done before Leitch crossed, the two gases were discharged from the negative and positive electrodes of the solution respectively, so what Leitch has to do is to make the pool form a complete circuit in the process of energizing, and the two gases will naturally be discharged separately! This is why there are copper rods and iron rods inserted in the pool, and some glass instruments are also sleeved on the rods.

In fact, these arcanists who participated in this operation, they also discovered the existence of these things, they didn't think these things were useless, but they really couldn't understand what the use of these things was! You must know that they are at least all arcanists, and no matter how talented Lei Qi is, he is just a magician at present! This kind of knowledge gap makes these strong people secretly can't help but feel a little more awe of this young viscount!

When he learned that Elliott led the Order of the Guardians of the Holy Sepulchre to surround Purgatory City, Reich faintly had the idea of taking the fire out of the fire! You must know that Purgatory City is a real 'main city', and even in the entire Dawson Federation at present, there are only nine (not including the fallen Frost City)! Once he can successfully capture Purgatory City, then he will really open a new journey, and the status of the Black Wind Territory in the entire Dawson Federation will not be the same!

Of course, in the face of Purgatory City, which has a natural geographical advantage and is heavily guarded by an entire Death Knights, Reitch has almost no possibility of capturing it! Not to mention that between Starmist Valley and Purgatory City, there is still a Hawker Mountain Range hundreds of miles wide! This huge moat constitutes an absolute safety belt between Starmist Valley and Purgatory City! This is almost everyone's knowledge, but it is precisely this recognition that provides Reitch with the possibility of capturing Purgatory City-as long as he can lead the army over the Hawker Mountains!

Of course, at that time, Reich only had a vague idea, after all, no one could say what the situation in Purgatory City would turn out to be in the end. However, Leitch undoubtedly belongs to the type that does what he thinks, even if there is only a 1 in 10 million possibility - because the temptation of Purgatory City is too great for him!

Of course, even if Leitch really came up with the airship in the end, he might not be able to use it. However, at that time, Leitch was only in a prepared mentality, not to mention that the equipment that can realize air transportation such as airships, Leitch believes that it will always be useful!

After deciding to tinker with the airship, it didn't take much time for Leitch to solve the problem of gas raw materials, that is, the production of hydrogen by electrolysis of salt water. However, it is not enough to solve the source of hydrogen, but also to consider what materials are used to hold hydrogen!

This is not an inconsequential question, you can't let Leitch use linen or animal skins to make airbags, right? Elegant or unsightly, the former leaks, and the latter is too heavy! As for the earth, most of the commonly used materials for making airbags are extremely flexible rubber capsules, but where did you let Leitch pour rubber at that time? Even whether there is rubber in Andrew's plane is another matter!

Leitch confined himself to his study and pondered it for three days, but he still couldn't come up with any practical solution. However, Leitch is not the kind of person who has no tendons, since he really can't think of it, Leitch simply reads a book to relax himself--for him, this is also his usual way of divergent thinking! In fact, many of Leitch's whimsical ideas burst out unexpectedly in the process of reading idle books.

Leitch casually took a book from the shelf at that time, and looked at the title of the book, which turned out to be a travelogue called "Heavenly Wind Travels (Volume 1)". Speaking of this travelogue, Leitch has read, probably about the Thunder Calendar (the calendar of the Roland Empire) about 3400 years, a bard named Robinson of the Roland Empire, in an expedition, accidentally broke into an ancient teleportation magic array of unknown age, and was finally inexplicably teleported to the southern coastal area of the Oakland Continent Eternal Night Elf Country - Tianfeng!

In this land called Tianfeng, Robinson experienced a completely different geographical appearance and elven culture from the Valley of Dawn, which is described in great detail in the travelogue of 11 million words in "Tianfeng Travels". The author of this travelogue is still quite good, and it has made many readers who have read this travelogue have an infinite yearning for the magical land of Tianfeng! In fact, it is precisely because of this travelogue that many adventurers will be prompted every year to take those merchant ships that lead to the Eternal Night Elf Kingdom and pass through the Ghost Sea (the Endless Sea to the east of the Dawn Valley, the Ghost Sea to the north, and the Ember Sea to the south), in order to finally set foot on the mysterious and charming land of Tianfeng!

When picking up the book "Travels in the Heavenly Wind," Leitch couldn't help but recall some interesting episodes that he had seen in the book, for example, in the book, Robinson had come to a large city called 'Flea City'! In fact, he was named "Flea", did he think this city was very strange? At that time, Robinson also thought the same, and what was even more bizarre was that when entering Flea City, Robinson actually saw a very unusual carriage -- the flea carriage! To put it simply, this carriage was actually a huge flea! How big is this flea? Robinson describes it in the book as four stories tall, so just think about it!

At that time, Robinson was also very interested in this flea carriage, and after asking the local dark elves, he learned that this large flea beyond his imagination seemed to be the experiment of a dark elf alchemist. It is unknown to outsiders what the purpose of the experiment was in the first place, but one thing is clear, the big flea has been around for more than 5,000 years! Even after the alchemy master is gone, the big flea is still alive and well, and has evolved into that unprecedented huge size!

Fortunately, this big flea was extremely tame, and even after the death of the alchemist, it never made any moves to harm the locals. And when the alchemy master was still alive, he transformed the big flea into his own exclusive 'carriage', and often sat on the back of a big flea and traveled far away - because the flea can stay on the water, this 'flea carriage' is undoubtedly quite convenient for the alchemy master, and the waterway is available!

In the old age of the alchemist, he transferred the flea carriage to the city where he had lived for countless years (now Flea City). At first, no one dared to bang this thing, but after a period of time, after being convinced that this big flea was indeed harmless, the lord of Flea City stepped forward and truly defined this flea carriage as a 'carriage' specially used for transportation!

The first time Robinson saw such a peculiar carriage as the 'Flea Carriage', he couldn't help but feel the urge to experience it! According to his travelogue, the interior of the Flea Carriage was arranged like a hotel, and it was extremely spacious enough to accommodate 300 people at once!

When Leitch first saw this paragraph, he couldn't help but have the urge to think of the so-called Flea City to take a look, and wanted to see if the strange 'Flea Carriage' still existed today!

However, when Leitch picked up the biography again, he quickly turned over the fragments, and finally his eyes settled on another strange creature recorded in the travelogue—the hanging jellyfish!

The hanging jellyfish has the shape of a jellyfish, and the body size is relatively large, and the average adult hanging jellyfish is about the size of three or four grinding discs. And this kind of hanging jellyfish is also quite aggressive, for those creatures who dare to approach them, they will be violently attacked! But the real characteristic of this kind of jellyfish is that, just like their name, they usually hang on the surface of the water, only the end of the tentacle has contact with the water surface, about four or five meters above the water surface!

Hanging jellyfish are a characteristic creature in the Tianfeng region, which is not uncommon here, and even the dark elf hunters here often form teams to hunt these jellyfish, because the jellyfish skin peeled from them is a pretty good leather material!

That's right, at that time, Leitch's inspiration flashed, and finally his eyes were fixed on the three words 'jellyfish skin'!

Although the hanging jellyfish can only be found in the Tianfeng region, and there is a ghost sea separated from the Valley of Dawn for an unknown number of miles, but in the endless sea of the Valley of Dawn, there are also many species of large jellyfish! Many of these large jellyfish even belong to the category of sea beasts, and some of the more ferocious jellyfish sea beasts will even attack those ships sailing in the endless sea!

Therefore, for those seafarers who go to sea all year round, jellyfish skin is also a kind of income they earn. Of course, it is possible to turn into 'dry food' when there is a shortage of food! In short, jellyfish skins are not uncommon in the Valley of the Dawn!

With the help of the Black Wind Chamber of Commerce, Leitch quickly collected a lot of jellyfish skins, and after testing, it was also proved that the air bags made of jellyfish skins could indeed meet his needs - light, elastic, and air-tight!
