"Actually, it's very simple. Su Fan took out a board and began to draw, "I can only give you a reminder, and the rest is up to you to comprehend." ”

"Hmm," Leonardo nodded vigorously.

"First of all, if the boat wants to travel at high speed, under the same engine power, then it is necessary to reduce the resistance, then we call the hull elongated!" said Su Fan, who drew a slender hull on the paper.

"But with such a thin hull, the accuracy of the main gun fire is too poor, right? The hull is shaking too badly. Leonardo could see it at a glance.

"Then that's what it is..."Saying that, Su Fan widened the middle of the hull and turned it into an elongated pipa hull, "The middle is widened, and the ends are thinner, so it is suitable for high-speed driving." ”

"That's it!" Leonardo's eyes lit up.

"Also, don't you feel awkward when you attack?" Su Fan asked, the mechanic has to control all the guns on his body at the same time, but the caliber of the main gun and the secondary gun are different, the specifications are different, and the control has the same flaw as the previous battleship of the dreadnought, that is, the problem of fire concentration.

"How can this problem be solved?" Leonardo has entered the role.

"Look, it can be like this..."Su Fan installed all four turrets on the central axis, and canceled the secondary guns, she pointed to this design and said: "You see, this layout, when firing on the side, there are four turrets that can attack the enemy at the same time, and the firepower after grabbing the T-position is much stronger than your previous layout." ”

"But once someone grabs the T-position, isn't the firepower in front of you much worse?" Leonardo pointed to the two turrets in the front section of the blueprint.

"It's not easy to solve, just raise this turret a little higher!" Su Fan raised the position of the turret a little, this is just a layout, not a real shot, so just draw it, this layout is called a knapsack turret, the main gun arranged on the central axis, the knapsack turret and the design of the whole main gun, these three concepts are the pinnacle of ideas, whether it is Yamato, Iowa, Bismarck or King George V-class battleships, the pinnacle of these battleships, are a combination of these three ideas, although this layout does not allow forward shooting, but don't forget, it is only because the concussion of the cannon will hurt the gunner of the turret below, but the mechanic does not have a gunner.

Leonardo was already stunned, he heard this theory, and he was there in a daze with this extremely rudimentary drawing.

"Well, it's just an idea, though. Su Fan continued there, "You know, a battleship is not a small ship, just use a nail to nail it, but the battleship needs to go through countless experiments and calibration, and it took a long time to complete this ship type alone. ”

"Then Shiyan slowly?" Leonardo asked, contrary to the battleships on the earth, the transformation of the battleships on the earth is basically to transform the turret and replace the weapon or something, and the transformation of the hull is hehe, but here, the mechanic can greatly change the hull of the battleship of the mechanical spirit body according to his own needs, and the weapon of the battleship is not so easy to change because it is made by an alchemist, even if the mechanic himself is an alchemist, it cannot use the liliang of the mechanical spirit body to change the basic performance of the weapon.

"Shiyan, of course. Su Fan said, a battleship from design to service is a difficult process, the speed, firepower and armor of the battleship must go through strict calculations and experiments to achieve a balance, not to mention anything else, take the freeboard of the battleship as an example, the high freeboard battleship shoots well, but the hull is wider, the wider hull will have a longer length, more armor, greater tonnage, tonnage up, power must also be up, and weapons must be changed accordingly.

Leonardo, who wanted to understand this, his face was worried, although he didn't have so much knowledge of Su Fan, but he knew how difficult it was to design a battleship, otherwise the current mechanics Weishenme were still using the battleship design of their predecessors, and they would use the corresponding ship type for each displacement level, just in terms of weapons and power, and those more alternative design drawings would cause countless mechanics to compete as soon as they appeared.

"Well, I've got a nice design here. Su Fan began to show her fangs, she has a lot of battleship designs, and "Soul Battleship" has incorporated a lot of battleships that exist in reality, and there is also a simulator in the game system, which is used to simulate the battleships that are combined with various jishu, and it will not make players build a "battleship that is extremely perfect except for not being able to float on the water".

"Really?" Leonardo's eyes lit up.

"Of course, but...this design drawing..."Su Fan's right hand began to make a gesture of counting money, this shijie has banknotes, and this posture is universal.

"Whatever you want, I'll promise anything!" Leonardo said immediately, the battleship blueprint, that's an absolute secret, can it be bought with money?

"Well...let's get 10 million Grasse coins first!" Su Fan said, she didn't expect how much the design of an old-fashioned warship could sell for, and the price in her heart was 3 million.

"No problem!" Leonardo agreed! He pulled out a red card the size of a playing card, which was not a bank card, but a bearer check, and whoever held the card could withdraw the money immediately, but only in one lump sum.

"Give. Su Fan snatched the card, and then threw the drawing marked with detailed data to Leonardo, with detailed data, not to mention that this is just a simple three views, only the data of the appearance, but only the data of the appearance of the battleship is enough, according to this picture to change his appearance This is not a difficult task for a mechanic.

Su Fan looked at Leonardo's back and fiddled with this red card, no one can fake this card, I didn't expect to ask for 10 million when I opened my mouth, could it be that there is less opening? After looking through Heidi's memory, I found that it was really less, this shijie is a noble shijie, only one percent of the nobles occupy ninety-nine percent of the wealth, which leads to the aristocracy being so rich, just a few million or tens of millions of them can't be on the table, and Su Fan is very tragic to find that he was cheated in that auction house...

As a big family of the kingdom, the Tulip family could not have only rewarded Su Fan who saved his immediate family with only 1 million Grass coins, and that gem was worth at least tens of millions, but it was simply sold by Su Fan at a price of 1 million...and nothing else, even this design is not much for 100 million!

"I'll you, I don't have common sense to kill people!" Su Fan almost committed suicide by throwing himself into the sea...

Leonardo didn't know where to go since he took the blueprint, and Su Fan didn't care, he was secretly sad in that small nest, and he didn't hurt after a few days of injury, because Leonardo came again! This time he took a few more cards of that kind and gave them to Su Fan, a total of 100 million Grass coins, and he really had a conscience! She was so moved that she almost took out the steam turbine...but Zuihou's reason overcame her conscience.

The dreadnought-class battleship is so powerful for Mao, in addition to the design concept, the steam turbine is also an extremely important factor, this factor can even be ranked first, the output of the steam turbine is several times stronger than the reciprocating steam engine, which makes the speed of the dreadnought can be compared with the cruiser at that time, even if it hits Zuihou to fight hard, still the torpedo can't catch up with others!

Counting the money until her hands cramped, 100 million Grasse coins are a few red cards, Su Fan put these cards into her ring, but no, she still put them in the safest place - the warehouse in her body, this warehouse is now stuffed with a lot of steel, but a few cards are still stuffed in.

After sailing on the sea for more than a month, this time is boring, but Su Fan found a good place when he came out unintentionally at night, this place is the top of the bridge, which is not high, so there is no lookout, but standing on the bridge, you can see everything on the deck at a glance, what is on the deck? Of course, it is a mixed hand-to-hand combat competition, and it is also a multiplayer competition with heavy taste!

Generally speaking, this kind of mercenary people who make a living basically know that they may die one day, so they are very open to some things, such as the three inches below the navel, there are a lot of female mercenaries, except for a few female mercenaries, the others are very open, in the face of whether they can see tomorrow in this kind of life, male and female mercenaries meet as soon as they are dry firewood, some time before the start of some dangerous missions, it is very common to have an open-air snap meeting or something, but there is no one a few days before the start of the mission, because the mixed hand-to-hand combat between men and women is too physically demanding。

There is still a week to arrive at the destination, this time it is zuihou once, so except for some people on duty, all the people went to the deck to participate in the mixed hand-to-hand combat activities, although there are fewer female mercenaries, but a woman can withstand N men!

"It's so exciting!" Su Fan used his night vision device to look at the scene below.

"Do you want to go down and have fun, or is it just here?" a flamboyant male voice rang out.

"You want to go yourself, I'm not interested in men. Su Fan had already discovered this person, but he didn't pay attention to him, anyway, these people are not afraid of being watched, if they are afraid of being seen, they are all in the house.

"Not interested in men?" the male voice was still unrelenting.

"I'm not interested, if you like women below a lot, if you like men below more, don't bother me here. Su Fan said impatiently.

"Yes, introduce yourself, my name is Anton Ju, and your name is Catherine, right?" the man kept buzzing.

"Hello Anton, Anton Zaijian. Su Fan waved his hand without replying and said.

"You..." Anton's handsome little white face showed a trace of anger, as a direct son of a great nobleman, except for those who are taller than his own family, or on an equal footing with his own family, who dares to talk to himself like this? You have to remember my name, because it's going to be the only man in your life!"
