Han Wenzheng finally made a final decision: "My Yanhuang clan has the ancient Great Wall to defend our borders, and today, we will also build a Great Wall on the sea to defend our people's sea borders, so I named this warship the Great Wall." There was no objection to this, and the name "Great Wall" became the name of a battleship that had not yet been built.

To build a huge warship, the first thing to finalize is the design drawing, everyone has no experience in this regard, Han Wenzheng is only relying on the experience in the earth era to provide advice, just the design drawing made everyone spend more than half a year to finalize the plan, of course, the design drawing of a large warship only took half a year is a little faster, however, they also have some foundation, so, it is not a big problem.

In the past six months, a lot of preparatory work has been done, such as preparing all kinds of materials, and building a large dock, etc., and countless tasks are waiting for everyone to do? The people in the logistics department were so busy that they didn't even have time to eat, countless materials were transported from Yanhuangcheng to New Shanghai, and many industries began to be established to strive for the best.

Construction has finally begun. For the whole battleship, there is no special design, just the design of the standard battleship of the Navy in the earth era, 200 watertight compartments on each side of the hull, a total of 400 watertight cabins, these watertight compartments ensure the anti-sinking of the battleship, even if more than half of the watertight compartments are in the water, it can also ensure that the battleship will not sink, however, this design is called a useless design by Hangul, however, it is still used for safety.

The armor of the battleship is divided into two layers, the outer armor is needless to say, of course, it is ranked first in terms of solidity and corrosion resistance, so to speak, how strong it is to build how strong, as long as all kinds of precious materials are available, they can be used to add them, and if they are not, they are necessary, and they must do everything possible to get it and add it to ensure the solidity of the outer armor and can resist more powerful attacks. As for the inner layer of armor, it adopts a one-piece structure, and all the armor is built into a shell, which is used to protect important facilities inside, such as engines. Suffice it to say that the design of the battleship as a whole gives it extremely high survivability.

In order to ensure the safety of the battleship and the need to install the formation, the whole battleship is built with special alloys, these alloys are not ordinary alloys, all of them are alloys that have been refined by a group of clansmen with true yuan, the defense is super strong, and the compatibility with the true element is very good, so that more formations can be carved on the hull, and the loss of heaven and earth vitality can be reduced to a minimum.

The design of the entire Great Wall is very large, with a total length of 280 meters, which is the opportunity of 28 nights, which is also used to facilitate the installation of the 28 nights of antiy array on the battleship. The widest point is 36 meters, the number of 36 Tiangang, from the bottom to the top, the highest reaches 108 meters, the number of 36 Tiangang 72 earth, from the bottom of the ship to the highest deck up to 18 meters, according to the design requirements, the waterline reaches 12 meters, the total displacement is up to 72,000 cubic meters, and its own weight reaches 36,000 tons. It's just that it's too hard to build.

A fire-attribute Yanhuang clan person can only refine fifty kilograms of alloys every day, so even if the power of the whole Yanhuang clan is used to refine alloys, it will take five years for the armor on the hull alone, and furthermore, these alloys need to be sent to calcining, and then made into pieces of standard plates, and various formations must be carved on these standard plates, and they can only be used after passing experimental tests, and this process will take longer, it is estimated that the hull alone will take about seven years to complete。 Just thinking about it makes people's scalps tingle.

In addition to the hull, it is not that the ship was finished like this, what about more equipment in the back? First of all, there is the problem of power, a ship of tens of thousands of tons of warships, without strong power is simply not able to drive, the previous Qian Tiexin designed the Yuan Qi engine has no way to produce such a large driving force, but also need to use the method of refining magic weapons to refine a more powerful engine, and, in order to get stronger power, Han Wenzheng spared no effort to use countless precious materials to make Qian Tiexin refine the engine, in a word, no one will think that the power of their ship is too big, only too small.

Qian Tiexin is busy like a dead dog every day, not only to design a new engine, but also to take care of other work, just the design and refining of the engine consumes a lot of his time, it took six years to complete the engine design and refining, he is really tired.

The power of the Great Wall is driven by 48 Yuanqi No. 5 engines, with a total power of 368,000 kilowatts, or about 500,000 horsepower, which makes the Great Wall have absolutely amazing energy, plus the propulsion of six steam turbines, which allows the Great Wall to run in the sea at a speed of 100 kilometers per hour, such a fast speed is basically unimaginable on the earth, after all, there is no such fast and huge warship on the earth. To put it to an extreme end, if you add enough wings to the Great Wall, it can fly.

The entire Great Wall is divided into three layers from the bottom of the deck to the bottom of the ship, and the bottom layer is a storage place for some sundries and various food supplies, which has enough space for the Great Wall to store more supplies, even if it does not dock for ten years, there is no need to worry about running out of supplies. The problem of food is not very big, as for the source of water, it mainly comes from the formation "Clear Spring Array", it can be said that even if there is no water on the ship, as long as the "Clear Spring Array" is activated, all the water tanks on the ship can be replenished within three hours, which is enough for the whole ship to use for several months.

The second and third floors are cargo warehouses, Han Wen is building only to find out that it was his own mistake, the Great Wall does not need to be so big at all, in addition to all the necessary buildings, there is more than half of the space is redundant, this is good, excess is redundant, just used for cargo hold, in this way, the Great Wall has changed from a pure battleship to a combined version of a cargo ship and a battleship, which also makes the Yanhuang clan and others ashamed: the power of the whole clan actually made a biggest mistake, or the lowest mistake. However, Han Wenzheng comforted and said: "It's okay, isn't it good to be a cargo ship? We don't need to build another cargo ship, one cargo is used for two purposes, killing two birds with one stone." ”

And the height above the deck reaches 90 meters high, of course, not the height of the main body, the main body of the battleship floating island is only eighteen meters high, divided into three layers, the first layer is everyone's accommodation area and dining area, there is also the entertainment area and other comprehensive areas, after all, the Great Wall does not need too many personnel, the design of the standard crew is only five hundred, so, there is space, it doesn't matter if it is wasted, besides, to go to the Western Continent, but it will take a few years, there is no entertainment facilities, wouldn't it suffocate people to death, so, there is still something to have, for the sake of everyone's mental health。

The second floor is where the headquarters and various functional rooms are located, where there are the most complete functions, all kinds of functions must be readily available, including staff rooms, combat readiness rooms, etc., each room has a lot of space, anyway, there is a lot of space, and the space is so large that even Han Wenzheng feels a little too much.

The third floor is the practice room, where there are all kinds of cultivation facilities, which can be used by the crew to practice, the journey is so far, cultivation is the right way, build it, anyway, it doesn't cost any more space, it is also a good thing to improve the ability of the crew, and there is a place for the crew's pets to rest, the bodies of these pets are very large, and the third layer is enough to place them.

The entire building above the deck is concentrated in the middle of the ship, starting from the bow of the ship at 40 meters to the stern of the ship at 40 meters, a total of 200 meters long, the length of the third floor is also more than 160 meters, the width is about 28 meters, the overall look seems to be a stepped structure, the appearance is very neat, it looks very comfortable, for the sake of beauty, the Yanhuang people have also spent a lot of thought.

And above the third floor, there are one hundred and eight tall masts, the largest is the middle one, as thick as ten meters in diameter, up to 72 meters high, the others are very tall, but not as tall as the main mast, this is not for play, but for another wonderful use. Of course, the Great Wall is an infinitely powered battleship, so naturally there is no need to hang sails on the mast.

With the Great Wall slowly taking shape, everyone outside can see it from afar, after all, such a big ship is a simple dock can not be completely covered, and it is not a shipyard in the age of the earth, such a large warship, so that the sea tribes in the East China Sea feel surprised, although they have not seen many warships, but some of the sea tribes that have run through the West Sea have also seen the ships of the West Continent, but, compared with the ship built by the Yanhuang tribe, it is impossible to compare, in the face of such a warship, they have not seen it, I don't know how powerful the Dao is, under curiosity, they want to do everything possible to visit nearby。

In the face of the curiosity of the Sea Clan, Han Wenzheng did not object, this is nothing, anyway, the Sea Clan can't see what is mysterious in it, the Yanhuang Clan's mastery will not be so easy for people to learn, besides, if the formation on the Great Wall is not activated, not many people can see the mystery, it is no different from ordinary ships, therefore, Han Wenzheng is also very generous, open one day every month for the Sea Clan to visit, and it is good to satisfy their curiosity.

The Great Wall was finally completed, Han Wenzheng also felt bitter in his heart, the Great Wall was very powerful, but it also consumed all the family wealth accumulated by the Yanhuang clan over the years, and all the precious materials were used up, if you want to refine a better magic weapon in the future, you need to find materials again, it hurts to think about it, so many precious materials are just exchanged for such a warship, I don't know if it is worth it, alas! However, seeing the terrifyingly large and heroic posture of the Great Wall, Han Wenzheng's heart was much more comfortable, this was his ship, a powerful ship.

The whole Great Wall is silvery-white, very beautiful, and there are two big characters written on the bow of the ship: Great Wall. The port number is 001. When all the sea clans saw it, they all thought it was too beautiful, if they could have such a ship, they would drive away, and the others would not envy death, and all the people were amazed and admired.
