Ling Meimei looked at the small wrench in Xu Zheng's hand and was envious and jealous, it was only the size of Xu Zheng's palm just now, and it looked much more delicate than an ordinary wrench, and it was marked with the words "special grade" in dwarf characters, and it was obviously more suitable in the hands of a dwarf than in the hands of a human race. Ling Meimei thought about this little thing, its actual value was far less great than its honorary value, and no one who was not a dwarf technician could understand the glory it represented.

Ling Meimei took countless tests and only got a wrench that represented an intermediate technician, and this guy easily made a special one, which made Ling Meimei very unhappy. You must know that in the technician certification system of the dwarf clan, the special grade is already the highest level, and there are only six special technicians in the entire dwarf island, including Xu Zheng, a foreign product. It's not just a skill that can be obtained by reaching the super level, but it also has to make a particularly great contribution to the gnomes. But when she turned her head and thought about it, Ling Meimei was also quite convinced by Xu Zheng, that ghostly Terran boy didn't know how to grow his head, even if he started learning from his mother's womb, it seemed that he shouldn't be able to pretend to have so much knowledge, but he knew a lot of things, so much that it was a little scary, just like the concept of this submarine, even if he thought about it with a stomachache, he couldn't think of such a thing. The significance of the submarine to the dwarf race is indeed incomparably great, which means that the dwarf race may also be able to pass freely on the Aris continent in the future without having to appear in front of other races, avoiding greedy coveting and unnecessary adventures. With such thoughts, although the little dwarf girl envied Xu Zheng for having a toothache, she just had to admire him.

Xu Zheng didn't know that he had become the imaginary enemy of the little girl, and he planned to make achievements in dwarf technology in the years to come, defeat this super-grade Terran dwarf technician who seemed to be a little invincible, and let him see how powerful he was. He devoted himself to the construction of the two transoceanic means of transport, hoping that they would soon be realized to build a bridge of trade between the Orson Manor and the imperial capital of Zion.

The design and manufacture of submarines and airships were carried out at the same time. The former is undoubtedly much more appealing than the latter. Flying machine gnomes have already been built, and what can be sailed underwater is still just a concept. Which thing is more interesting, which thing attracts people, and you can think about it with your ass. In this way, there is the only surprising and strange phenomenon in the history of dwarf design and manufacturing: the dwarfs on the airship side are all passive and slacking off, and they run to the area of submarine design and manufacturing one by one, putting down their serious work and not doing it. But I ran here to help, and I was very proud.

Xu Zheng had a headache about such a situation, of course he knew the benefits of submarines, but he also knew the benefits of airships. Scientists in previous lives calculated that the cost of transporting a ton of cargo by airship was 68% less than that of an airplane and 94% less than that of a helicopter. Half less than trains. The cost savings are enormous, much more powerful than submarines. In addition to the basic purpose of the submarine to dive into the water, it is also very good in terms of safety and concealment. It costs only as much as ordinary water transportation. To be precise, not only high, but too high. Therefore, strictly speaking, it is not suitable for use as a means of transportation.

However, they are not aware of this, they are almost all crazy scientists, in their opinion, cost is not a problem at all, the key question is whether they can innovate new technology and create new things. Therefore, Xu Zheng has to supervise this group of 'unprofessional' little people at all times, and steer their research direction in the right direction - this is how to use the technology in his hands to better serve the public, instead of creating something impractical. Or maybe it's something that hurts.

Considering that the appearance of submarines in the Aris continent is indeed a bit against the sky, Xu Zheng and the dwarf people have reached an eternal agreement on the use and manufacture of submarines:

First of all, unless a submarine is used for self-defense, it is not allowed to participate in war, no matter what form it takes, even if it transports war materials. Secondly, submarines used for transport must not carry any kind of shipboard weapons, with the exception of personal self-defense weapons. Third, submarines can only be used by gnomes for their own use, and they can never be sold or designed and manufactured for other races, including drawings and related technology. After agreeing on these three agreements, Xu Zheng minimized the possible harm caused by the submarine as much as possible.

According to the above, the airship also signed a similar agreement, and Xu Zheng really put his mind at ease and let go of his hands to design and manufacture them with a group of dwarfs and dwarves. Xu Zheng just wants to use what he knows to build a better Aris continent, instead of making this green land that is primitive but full of endless breath of black smoke and miasma, and then go to the old path of self-destruction in the interstellar war in his previous life.

In this way, nearly a month later, the first airship was successfully developed and will be put into testing.

On this day, the weather was sunny, and even the heavy snow was very face-saving to stop. Although the weather was still cold, the sun was glowing slightly white in the air, and even the air at the mouth of the air was forming a white mist, everyone who had time in Orson Manor still came to the square in the middle to visit the official flight test of the first airship together.

Prior to this, the airship, named Chenguang, had successfully lifted off four times, including the first flight test, the second directional maneuvering test, and the third and fourth propulsion tests. Today is the fifth time, and what will be done is a test flight within a radius of 30 kilometers. In other words, it has to be centered on the Orson Manor, and it will be able to fly for a long time of more than 100 kilometers with a circumference as the path.

The name Chenguang was taken by Xing Badai, and as soon as the name was spoken, everyone thought it was catchy, easy to remember, and full of hope and longing, it was really a beautiful and beautiful name. For this reason, he also made a big contribution to the little princess of the elf clan, but he broke the star bardel. If it weren't for the fact that she knew that she couldn't possess this thing, the elf princess would definitely go to Asban first, then go to Xu Zheng, and finally talk to the dwarfs and classify this first airship as her mount.

Coveted, coveted...... Star Badai drooled and looked at it with red eyes.

The volume of the Chenguang is not small, with a length of 40 meters from the front to back and a maximum width of 30 meters from the left and right, and the whole is a three-layer structure in the shape of a spindle. The top layer is a hard-skeletoned airbag that can provide up to 20 tons of buoyancy when filled with gas. The second floor has a diamond-shaped structure, and the main cargo compartment, living cabin and power take-off are all on this floor. At the same time, it can also be used for people to walk on when flying at low altitudes. The third level is technically integrated with the second layer, and the gnomes designed a sealed dinghy embedded in it. It can carry up to twenty-four passengers. If necessary, it can also break away from the second layer and escape by parachute attached to it. The main power equipment and control equipment are on the second layer, and the third layer has a set of auxiliary ones, which are mainly used for high-altitude riding and escape. At present, the entire Chenguang is the first sample, in addition to being used to reduce drag and maintain a stable wind force field in the wind. Everything else that doesn't use any magic system, from power to manipulation, is all made possible by the gnome's equipment.

Using the current technology, Xu Zheng thinks that the gnomes can do this step is quite powerful. The entire Chenguang stopped in the square, and it did not have the smooth and gorgeous beauty of the modern airship, but it had a simple and heavy atmosphere nurtured by the unique cultural atmosphere of the Aris continent, and it was very safe.

Something forty meters long and thirty meters wide stopped there. It's just a behemoth. The dense crowd of Orson Manor gathered there to watch, enclosing the entire square.

In the afternoon, after a loud whistle, the airbags on the first deck of the Morning Light began to inflate. Sixteen pieces of equipment that could produce nitrogen began to fill it with gas. Xu Zheng's original plan was to use hydrogen, because the gnomes could already easily make it. Later, considering the danger of using hydrogen, it was much better to use nitrogen. The plan was changed. Nitrogen is an inert gas that is non-flammable, and even a small amount of leakage is not a big problem and does not affect flight. If the leakage is serious and affects the flight plan, as long as it is found early, it can also be repaired. Even if it can't be repaired, it can still fly back to the base for maintenance and then take off again, and the safety factor is quite good.

Xu Zheng thought that it would be difficult to make nitrogen in the Aris continent. Because in his original time and space, nitrogen was obtained by separating and refining natural gas with a helium content of about 0.5%, which was mostly not possible here. As a result, he only inadvertently mentioned it, and in less than two hours, Forrester and Adam used alchemy to make nitrogen gas for him...... Xu Zheng was speechless about this, and deeply felt that the most rebellious thing in the Aris Continent was probably this alchemy. Later, the old mentor, Adam, and the gnomes teamed up to try out these sixteen pieces of equipment for filling the air sacs with nitrogen, which had the disadvantage of being slow and not small, but the advantage was that as long as the materials were sufficient, they could be continuously charged. As for the small, lightweight nitrogen generator, the Chenguang is loaded with eight small backup models, and the rest of the time it is more efficient to use the ground. These eight spare ones are of course slower than the sixteen on the ground, but it's better than nothing, at least they can win some time for emergency repairs, and Xu Zheng and the gnomes summarized it as one of the life-saving equipment.

Because the airbag that provides buoyancy is so large that it took nearly a month for the excellent weaver of the whole elf clan to make such a material out of the silk used by the elf clan, so it took two and a half hours to fill it.

Hawke stood on the ground and covered the sunlight with his palms, looking at the airbags that had floated and the parts under it were also floating, and he was a little proud in his heart. This kind of thing, except for Orson Manor, I am afraid that there is no other place in the entire Aris continent that can make it. Just look at its appearance like a big fat man with infinite strength, if it weren't for the ten anchors that fixed it on the ground, it would have flown up.

"Xu Zheng. Hawke looked at Xu Zheng.

Xu Zheng nodded, and there was a little excitement in his heart. As for the airship that can be transported across the ocean, the first one has finally been built.

Seeing Xu Zheng nodding, Hawke suppressed the excitement of witnessing this moment, waved his hand, and shouted, "Anchor!"

The Cowherd was holding a small tricolor flag in the distance, proud of Huo Huo's special effort to grab this face-saving job, the original plan was to call the beautiful flag officer of the Starlight Song and Dance Troupe to do this, but now it is him. Listening to Hawke's voice, the bull head raised the banner of release, and shouted in a loud voice unique to the minotaur: "Anchor and release!"

Ten anchors were retracted, and the entire huge Morning Light did not shake in the slightest, but only leaped off the ground and rose upward, its fat body slowly climbing up in a manner that seemed completely incommensurate with its appearance, and was even lighter than a bird. This action alone reflects the advantages of the airship, that is, the flight is stable, vertical take-off and does not consume fuel during lifting, it seems to be bulky, but in fact, it is lighter than a bird when taking off and landing.

"Flying!"

"Flying!"

"Of course it's flying again, hahaha!"

The airship was successfully lifted into the air, and the sound of color thundered below, and the children jumped and cheered loudly under it. The first time people saw it, they still didn't believe that the big creature could fly, but it flew with an unexpected lightness. And those who have already seen it fly still can't help but applaud excitedly, only feeling that no matter how many times they see it, they still feel very enjoyable.

After the Morning Light took off, the rest of the control was taken over by Ling Meimei, who had almost become the test pilot representative of the dwarf clan, and she was indispensable every time there was a test of something new.

"Fifteen degrees to the left, 20 percent power. Schlenlun put the telescope to his eyes and looked to the left, and exclaimed. He is the navigator.

At the sound of the command, the Ameritor showed a clumsiness commensurate with its size, and slowly turned fifteen degrees to the left, and then four huge propellers spun under the impetus of the steam engine, propelling the Ameritus towards the sea. According to the predetermined plan, it had to fly 30 kilometers in a straight line first, and then fly more than 90 kilometers in a circle after reaching the predetermined point, a total distance of more than 120 kilometers.

Seeing that it successfully flew away according to the correct flight path as expected, even Xu Zheng himself couldn't help cheering this time. There were a lot of people gathered under the Morning Light, all running down with the airship that was gradually increasing in speed, and their mouths were constantly whistling. The children were even more happy, and they simply regarded this test flight as a celebration.

Xu Zheng felt that there was no need to look at it, and if nothing else, the experiment would definitely be successful. According to the plan, the Chenguang will fly in a circular orbit with a radius of 30 kilometers with Orson Manor Square as the center, and finally land on the square to complete its maiden voyage.

Xu Zheng covered his eyes with his palms like Hawke, watching the Chenguang fly farther and farther, and the corners of his mouth slowly curved upward. He knew that the passage between Orson Manor and the Imperial Capital Zion would be opened, and the aviation history of the Aris continent would take the most important step!

I secretly cheered in my heart, but I saw Bruce with a gloomy face, striding towards him from a distance.
