Liu Ziguang sat on the beach, not to watch the soldiers play volleyball, he put on his sunglasses again, and set his eyes on the sea in the distance, the sea was like a forest of masts and chimneys, wisps of black smoke rose, the ship's boiler was running, and then looking up, there was a shocking dark cloud.

The brilliance of the sun is blocked by this dark cloud, only the dazzling light from some gaps sets off the evil of this industrial dark cloud, and it is said that it is a dark cloud, because there is really no language to describe such a huge, evil, and primitive industrial beauty of the sky city!

This is Liu Ziguang's hard work, but also the crystallization of the wisdom of all the technicians of the Ministry of Industry and the Royal Academy of Sciences in the Ming Dynasty, and it also integrates the various technologies of Liguo Iron Factory, Jiangnan Shipyard, Qishuyan Machinery Factory, and Wuchang Shipyard. This book is reprinted! Literature.com! I can't see his face, a large number of excellent technicians and operators, it took two years and a lot of manpower and material resources to make this freak, just the drawings have drawn more than 100,000 sheets, and the corresponding metal smelting and manufacturing process has been greatly displayed, and the silver spent on this thing is simply incalculable.

It's an airship, but it's not your average cigar-shaped airship, it's a city in the sky made up of a row of giant airships! Five 100-zhang long rigid airships are covered together, and the outside is covered with a fairing that conforms to the principle of aerodynamics, and the top of the fairing is a flat ground with a radius of 100 zhang, which can take off, and the rear of the power parachute is six high-horsepower propeller propellers, and when you need to turn to the left, you will start the two propellers on the far right, and when you need to turn to the right, you will start the two on the left, and when you need to move forward, you will drive six at the same time, and the operation mode is similar to that of the tracked armored car. There are also flat propellers on the upper part that act like helicopter rotors to provide auxiliary lift, which is not put into operation until the airship's buoyancy is lost.

As for the issue of lifting, the sky city has not considered descending since it rose to the sky, this is a symbol of science and technology and force in the Ming Dynasty, and it is also a symbol of human occupation of the sky, as long as it is constantly replenished from the ground, food, ordnance and special gases can hover in the air for a long time, showing its suffocating beauty to the world.

The interior of Sky City is the crew compartment and weapon compartment, because its volume is too large and it is not flexible to fly, so the main weapons are powered parafoils and small airships loaded with bombs, which is equivalent to saying that the real identity of Sky City is a space carrier, of course, other weapons also have a large number of bomb pylons, small-caliber guns are all over the lower part of Sky City, and the black pressure of the barrel is sticking out, hideous and gloomy.

The motive of the airship is the most advanced refining of fierce fire oil, the internal combustion engine of eighteen cylinders is flexible, the power is strong, the pollution is small, just in order to produce refined fierce fire oil, Liu Ziguang spent 100,000 taels of silver to build a petrochemical plant in Dongying, the fierce fire oil catalysis, desulfurization, and careful refining into clear color, extremely efficient refining refining oil calorific value is much higher than alcohol, is the most advanced fuel at present.

The most consumed material in the entire Sky City is high-strength aluminum, although the content of this metal element in the earth's crust is very large, but refining is very problematic, a long time ago, Addison according to the records of ancient books, using the fire smelting method to extract copper-rich aluminum from copper and aluminum minerals, and then replacing the copper inside to extract high-purity aluminum, but this method can only be used for laboratory production, large-scale refining costs are higher than gold. Moreover, the strength of pure aluminum is very low, except for being used as a wire, there is no other function, and later the aluminum alloy doped with other metals has the characteristics of light weight, high corrosion resistance and strength, especially suitable for aircraft.

So the Academy of Sciences threw themselves into the work of smelting aluminum alloys, and after countless failures, they finally came up with a solution: fusing cryolite and pure sodium together to produce aluminum and sodium oxide, aluminum particles and aluminum particles to make aluminum blocks.

Although the cost of this method is slightly reduced, it is still not expensive for ordinary people to bear, and the cryolite used needs to be transported from thousands of miles away in Yunnan, and pure sodium also needs to be refined in a special factory, and the price per catty of aluminum is equal to thirty taels of silver!

Pure aluminum is mixed with copper, zinc and other metals to create high-strength aluminum alloy instead of the original bamboo inside the airship, although the weight has not increased much, but the strength has greatly increased, Liu Ziguang received the report, resolutely decided to go on the aluminum alloy project, regardless of the cost! Smashing pots and selling iron will also carry out the project, the metal materials of the entire sky city are almost all aluminum alloys, and no less than 10,000 catties of synthetic silver are 3 million taels! It is not an exaggeration to say that the city is made of silver.

In addition to a large number of aluminum alloys, a lot of Nanyang rubber, silk coated with tung oil, and a large number of leather products, weapons are all made of steel, all the compartments are wired, telephone wires are different from ordinary, the use of the best signal of the sterling silver wire, not important parts such as handrails, railings or something, in order to reduce weight and save costs, the use of carefully selected bamboo.

The crew of the Sky City is even more carefully selected, the first is to be proficient in flying or other professional technicians, secondly, they must have strong psychological quality, cautious and careful, and they must not be used, and then there is absolute loyalty to Liu Ziguang, the crew's uniform is poplin, fire-resistant and wear-resistant, different jobs have different colors, the anti-collision wicker helmet on the head is marked with military rank, and there are pure gold Sky City badges on the chest, indicating their noble status.

Liu Ziguang has invested almost all of the money he has earned over the years in Sky City and its supporting construction, if it were not for the success of the state-owned China Merchants Bureau, the Meilin Canned Food Factory, and the Nanyang Brothers Tobacco Company, where would there be the money to make such a magnificent thing?

The city in the sky has not been completed until recently, Liu Ziguang didn't want this military secret to be exposed prematurely, so he asked them to pull several main components to Beidaihe to assemble, and only on the sea surface can there be enough space to assemble this big guy, everything is prefabricated and fastened together, the six airships are merged together, the aluminum alloy frame is laid outside, and then covered with skin and fairing, even if it is done, the connection between the internal cabins, and the laying of communication lines are very simple, and then the crew is stationed, the debugging of the weapon system, and the beautification of the shell.

The painting of the outer skin was handed over to 200 painters to complete, these craftsmen sat in the hanging basket and painted the sea auspicious clouds on the fairing of the sky city one by one, originally according to their intentions, they also wanted to draw the four heavenly kings, the eighteen arhats, and the best and 100,000 heavenly soldiers or something, Liu Ziguang did not think so, he thought it was better to be abstract and give people more space for reverie.

There are no people for dozens of miles around Beidaihe, and the Manchu Qing Dynasty issued a sea lock order, not allowing the people to enter the Ming occupation area, and the red shirts are not allowed to enter the Beidaihe area, so as to prevent leakage of secrets, of course, it is impossible for such a big project not to be known, at least it cannot be hidden! This book is reprinted! Literature.com! The soldiers under their hands, these rest soldiers have been watching them work on the beach for several days, and the initial shock has gradually faded, but when the sky city rises from the sea, they are still shocked again, and they drop their volleyballs, standing stupidly on the beach, one by one, their mouths wide open, and saliva dripping down.

It is claimed that not only them, but even Liu Ziguang was stunned by the devil summoned by himself, it is really spectacular! There are no words to describe the psychological coercion caused by this city in the sky, at that moment, Liu Ziguang understood that this fortress actually did not need to install any weapon system at all, as long as it appeared in the sky, everyone would be overwhelmed, shocked, defeated by the amazing power shown by the heavens, and even forget the hatred, forget the war, at that moment, they were just small human beings, humble reptiles.

The sun sinks in the west, the sunset is like blood, the silent fleet on the Bohai Sea outside Beidaihe, and the silent sky city reflect each other in the distance, forming an incredible picture, and everyone who sees this scene can't help but think: This is power, unparalleled power, what a strong city with high walls, and the strong army can only tremble and surrender under its king's landing. I don't know who it is, the first one, maybe everyone coincidentally, many people raised their heads and looked at the city in the sky, and raised their right hands to their foreheads, this is a simplified military salute within the Red Shirts, and when wearing armor or other work clothes, you can not bow down.

Liu Ziguang suddenly felt a pain in his fingers, it turned out that the cigarette had burned out unconsciously, he lost the cigarette butt, and solemnly raised his right hand to salute the sky city, salute the thousands of technicians and industrial workers of the Ming Dynasty, and salute the wisdom and labor of the Chinese nation.
