"What are you arguing for?" Sten walked in, and the first thing that mattered to the pickled girl was that she was thick-skinned.

"How do you place this watertight cabin?" Scarlet Moon picked up a simplified design drawing and showed it to Sten, this watertight cabin involves the correction of the hull after being hit by a torpedo or something, it is very important, Su Fan originally planned to use the simulation system to simulate it, but he didn't have time yet.

"Hmm..." Sten's eyes lit up when he saw the battleship with a beautiful streamlined appearance written by Scarlet Moon, but he didn't ask anything, looking at this design and began to be distracted, Su Fan didn't bother, turned on the simulation system, and began to simulate, the main body of this battleship is almost the same, just a few watertight cabins, explosion-proof doors and command towers.

"Cancel this watertight compartment and replace it with armor plates!" Su Fan and Sten said at the same time.

"Huh?" Su Fan and Steng were both shocked, Su Fan didn't expect Sten to be able to see that this watertight cabin was just a burden with such a half-cut drawing, and Steng was just shocked because the beauty thought of it with him.

"Do you have research on shipbuilding?" asked Su Fan.

"A little research, my family has always been interested in enhancing the combat effectiveness of warships through ship types, but it is useless to have enough strength in the haode ship type, so it is just a hobby. Scratching his head, Steng said, "Recently I've been working on the bow of a flying clipper and the streamlined hull, and this is just an idea, but I didn't expect you to make it happen." ”

For Sten, Su Fan was still not very relieved, so after talking about the ship for a while, he began to talk about other things, not to mention, Sten knew a lot more about many things on the mainland than Scarlet Moon, for example, two months ago, the king of the Kingdom of Vlaar was assassinated, although it was not successful, but it was in danger, several princes were busy seizing power or something, Su Fan was wandering on the sea, and Scarlet Moon was squatting at home, and he didn't know.

Of course, it doesn't matter what happens to the two of them, because as long as they can enter the Imperial University of Grass, politics will be temporarily far away, because the large number of outstanding graduates of this school and several generations of powerful presidents make the school beyond the imperial politics, although it has more or less influence, but it is far less serious than outside the school.

"It's a school exam, you know?" said Sten, pulling out a book.

"Exam subjects?" Su Fan and Scarlet Yue both leaned over curiously.

Royal University of Grasse is a super comprehensive university, which not only has mechanics, magicians, these main subjects, but also some messy sub-subjects similar to art, etiquette or something, the subjects of the examination are extremely complicated, in order to make candidates understand what they want to test, the school specially compiled this book.

Forget about magic or something, Su Fan and Scarlet Moon are not interested, their interest is in the sea mechanic, the test subject of the sea mechanic Scarlet Moon already knows, divided into written test and practical operation, if the written test has not passed, the actual operation has passed, then you can definitely enter, if the actual operation has not passed, but the written test has a very high score, it is also possible to pass, the written test part is not so important, but the actual operation of the two is attentive.

The actual operation is the actual battle, of course, the school will not let the candidates die, the location of the exam is about 30 nautical miles outside the school of a fortress, this fortress was originally a natural island, and later because of the good geographical location, the school spent a lot of money to change this big island into a fortress, reinforced concrete plus magic shield defense, it can be said that this big island has been reborn, it is completely a super-large building stacked with reinforced concrete!

There are countless large and small batteries, including 20 double-mounted main batteries, distributed around the fortress, the caliber of this giant cannon exceeds 900mm, there are hundreds of secondary guns with a caliber of more than 100mm, thousands of anti-aircraft guns, as for rocket artillery, it is difficult to count, there is a huge military port on the side of the fortress, which can berth hundreds of thousands of tons of super-large warships!

The reason why such a fortress was built is because the Royal University of Grasse was once captured in a war in which the uncivilized race attacked the human Shijie with all the members of the army! The overwhelming warships of the uncivilized race rushed over, and the imperial navy had no time to react, in order to make more people retreat, nearly half of the students and teachers were killed in the battle, although nearly 100 million uncivilized races were killed, but the biggest advantage of the uncivilized race was that there were many people, 100 million people were just a drizzle, and the people who died in the war were all human beings, the elites of the Glas Empire!

This trade is absolutely not suitable, after learning this lesson, this huge sea fortress was built, as long as this fortress does not fall, then no one can attack the school from the sea, this fortress cost the treasury of the Kingdom of Vlar to be established with the help of countless old alumni, and there are 100,000 troops stationed all year round.

Every year, the sea mechanic's exam is carried out with this fortress, of course, the exam cannot use live ammunition, the cannonballs used in the exam are all school characteristics, very soft, but the effect and trajectory of the shot are no different from live ammunition, and after the hit, a large area of colored traces will be generated, so that it can be determined.

The content of the exam is that individual candidates or candidates in a team attack the fortress, according to the number of candidates in this team to assign tasks and how much strength the fortress has, generally speaking, the task of a single candidate is to "smash" under the bombardment of several secondary guns In a certain area, the candidate's strength will be tested before the exam, and then the thickness of the candidate's mechanical spirit shield and armor will be calculated, and the soft cannonball will not cause damage to the shield and armor, so the school will judge the candidate's shield and the damage according to the candidate's strength.

"Attack the fortress..." Su Fan looked at the explanation in the book and had a great grasp of the success of the exam, the structure of the fortress can be seen by anyone from the outside, sometimes there are students who go to internships, so there is no deliberate cover-up of this, besides, this fortress is not used for war against humans, the human empire is too big, it is difficult to fight, and the location of the school is the hinterland of the Grass Empire, if the fortress can be used in the war against the human race, the Grass Empire is almost finished, so there is no need to keep it secret.

In addition to the cannon on the fortress, it is a magic tower, needless to say, the range of the cannon is tens of kilometers, but what is Su Fan, a missile cruiser! The range of the Basalt 8 type is 800 kilometers, of course, there is no satellite navigation or anything here, it can only be aimed with fire control radar, Mao Zijia's radar everyone understands, although the super large electron tube, although it can aim at things within a range of 500 kilometers, but if it is used for navigation, 100 kilometers will have to be kneeled.

However, 100 kilometers is also a chasm for the fortress, and it is good to fly a kite from afar, and the most difficult thing to do now is how to deal with this missile, is it to replace the warhead with that kind of soft egghead? But the missile is not an artillery shell, and that special warhead will not disintegrate under magic, but how can it be used on the missile? How can the missile's engine be solved? If the warhead is only removed, then the missile flying at a speed of several Mach is also a terrible weapon of great destruction, and it is no worse than a large-caliber shell.

As for how to explain the missile, it is much simpler, although the mechanic has not appeared for a long time, compared to the magician, but there are many ways of cultivation for the mechanic, some mechanic families have their own different cultivation methods, and the results caused by different methods are also different, some are good at running, some are good at fighting, and some can even fly for a short time, and it is not uncommon for a rocket to suddenly appear and make a rocket turn.

"What are you doing there?" Scarlet Moon put down the pencil in his hand, climbed to the edge of the container and shouted to Su Fan below, Su Fan has not been nesting in this humble cabin for the past few days, but is tinkering with a strange-looking columnar object on the deck, under closer observation, this thing should be a rocket, what are you doing with this thing?

"I'm studying how I take the exam..."Su Fan shouted, and continued to lower her head to dismantle the missile, dismantling the missile is the first time she has done it, but the electronic product is a family, as long as the screws are found, but what makes her depressed is that her missile has no screws...use brute force? The heavy tungsten alloy shell is a laser and it will be burned for a while, you let her disassemble it by hand? And even if you use violence to disassemble it, you are not afraid that this thing will ring and turn the entire Lu Xingzhou into a spaceship?

"What's going on?" Scarlet put away the blueprints and jumped out of the container.

"This is my shipboard weapon, but I want to take it apart and take a look, but I can't open it..." Su Fan gently hit the missile body with a small hammer, the tungsten steel alloy projectile made a crisp metal impact sound, the Granite 8 missile is 11 meters long, 1.2 meters in diameter, and the explosives with a warhead of 1.5 tons, there are four engines around the cylindrical missile body, embedded around the missile body, it looks like a bundled rocket, and there are four large triangular tails between the engines to maintain balance.

The entire appearance of the missile is that the tail of the big triangle is active, it is folded inside before launch, and it will stretch out after launch, Su Fan started from here, but this missile doesn't even have a gap, including the tail, so there is no way to start.

"Is this...rocket?" Sten curiously touched the giant missile.

"Guided rockets, you can fly as much as I want. Su Fan knocked on the body of the missile and said, there is a kind of rocket called guided rocket, the difference between this guided rocket and a missile...It seems that there is no difference, Guardian 2D and Condor 400, the two "rocket artillery" except for the country of origin and the country of purchase, no country recognizes that it is rocket artillery, but the scientific name of these two is called xxx rocket artillery...
