"Lina Linna, look at this steam turbine!" Scarlet Moon excitedly pointed to a large number of design drawings in front of her, this steam turbine was really beyond her expectations, according to the calculations of various data in the book that Su Fan gave her, the volume of the steam turbine is a little smaller than that of the ordinary reciprocating steam engine, but the power output is stronger, although the material requirements are a little higher, but where is this place?

"This...you design it very well?" Su Fan looked at the design drawing, and then used the simulation system to demonstrate it once, she only gave Scarlet Moon a similar design drawing and some concepts or something, but she didn't expect Scarlet Moon to design a steam turbine suitable for herself in these ten days, which can perfectly provide the power needed to propel a 25,000-ton battleship.

"Look at this!" Scarlet Moon said excitedly, a blue light flashed between her hands, and in this blue light, a small boat about half a meter long emerged, and this boat was another image of her mechanical spirit, "I've got this mechanical spirit ready, Xiexie you!"

"No thanks. Su Fan stretched out his hand and touched this cottage Nevada-class battleship, this battleship has been made all over the body, but it lacks all kinds of gun barrels, the gun barrels and hull are not the same, the requirements for gun barrels are higher than those of steam turbines, and the school does not give students free gun barrels, if you want gun barrels, you can buy them from the school's logistics department at a very cheap price.

"Linna, how did you do in the exam?" Scarlet Moon asked Su Fan after putting away her mechanical spirit body and lying on the bed.

"There's nothing wrong with the written exam, but I don't know how to solve the actual exam tomorrow?" Su Fan also lay on the bed, but his head rested on Scarlet Moon's soft chest.

"Ah!! don't press it, it's not big, and if you press it again, it's even smaller!" Scarlet Moon quickly pushed Su Fan aside, then sat up, and pinched his chest with his hands, as if such a pinch could pinch out the point where Su Fan was pressed back just now, to be honest, Scarlet Moon's breasts...It's really a little small...but it's bigger than Su Fan...

"What's the use of being so nervous, no matter how big it is? Su Fan took out a famous quote from the earth.

"Cool yourself?" Scarlet Moon was confused by Su Fan's words, but soon she understood, and her face became a little red, "Linna, you are too sexy, you perverted girl!"

"It's a fact!" Su Fan said without saying (yes).

"I won't tell you!" Scarlet Moon hugged the quilt, wrapped herself in a cocoon, and then shrank to the side, Su Fan didn't provoke her again, and fell asleep holding the quilt.

The next morning, the two woke up from the hug again, got up, washed their faces and ate and went to school in one go, the school was on the seaside, after passing through half of the school, they saw the endless sea, in the distance, you can see a small black dot on the sea, this small black dot is the school's sea fortress.

Don't look at the fortress now, it is very small, but this fortress has a huge size of 11.6 kilometers long, 12.4 kilometers wide and more than 400 meters high, the entire fortress is one, with a thickness of more than ten meters of reinforced concrete and more than 200 mm thick metal armor plates, in this era when there are no armor-piercing bullets under the hood, coupled with a heavy magic shield, this protection is invincible.

According to the instructions of the note in his hand, Su Fan found the port where he took the exam - Port 12, the number of marine mechanics is very small, and even fewer can pass the first level of the school's audit, and there are few people in sight, Su Fan is the twelfth group, there are 5 people in a group, and the invigilator is...

"Ekaterina, huh? If you're afraid of breaking the fortress, you can set a false target next to it. Su Fan looked at the cottage with a dark face, and Snape's two thin lips spewed irritating words outward.

"I'm not afraid of breaking the fortress. Su Fan decided to teach this thing a lesson, as for what lesson?

"Then you can attack the fortress directly, don't worry, even if it is broken, you don't need to accompany you!"

The exam is divided into two parts, the first part is to test the attack power of the candidates, so that the damage of the fortress can be calculated according to the number of candidates hit the fortress during the exam, the protective shield of the fortress is nothing for the salvo of one or two warships, but it also needs to be consumed to open the protective shield, so it is simply not opened during the exam, anyway, the shell falling on it is at most a mark.

In Su Fan's group, there are three battleships with a displacement of about 25,000 tons, these three candidates are only single mechanical spirits, and the other one is a retro sea mechanic, this retro sea mechanic is an indifferent teenager, when Su Fan's eyes looked at him, a playful smile appeared on his face, and then two words "garbage" spit out in his mouth! Indeed, Su Fan's 19,000-ton arsenal ship is indeed a little thin in front of a bunch of 25,000-ton battleships.

At the beginning of the test, the candidates were launched, four huge steel battleships and a dark red sailboat appeared on the sea, the battleship was nothing to look at, the length was about the same, two rows of six turrets, the retro sea mechanic was very small, only 40 meters long, this wooden boat rose and fell in the waves caused by the four giant ships, but no one dared to underestimate him, the retro sea mechanic is a powerful representative, sometimes even the battleship is not an opponent.

Several candidates were very curious about Su Fan's strange shape, such a large hull was only equipped with two twin turrets, and the barrels were square (there were armor on both rails of the electromagnetic gun to prevent mutual influence), so a large deck in front was empty, what was it doing empty? What was it doing with such a large deck in the back? Could it be a whiteboard mechanic? But how could a whiteboard mechanic pass the initial test?

Snape of the cottage didn't know if it was a sea mechanic, he didn't deform, but walked in front in a small destroyer with a displacement of about 1,000 tons, followed by five candidates, this small destroyer came to a shore not far from the school with several warships, on the shore was a rocky peak, but the mountain had been cut in half, and it was still decreasing, because this was the first part of the actual combat test, which was to test the attack power of the candidates.

Although the mechanic's artillery has high requirements for artillery, but its own strength is also an important condition, the same artillery is more advanced mechanics to exert greater power, although the school does not stipulate the quality of artillery, but if the use of high-quality artillery can not hit the corresponding attack, the exam will also be deducted.

At this time, many candidates are taking turns to fire at the mountain, and their respective invigilators are on the edge of the group on the boat to look at the bullet point, and then analyze the candidate's accuracy according to the quality of the artillery.

"Who's going to go first?" said Snape.

"I'm coming!" said the three battleship sea mechanics.

The guns of these three marine mechanics are all 308mm, but the barrel is at most 30 times the caliber, this kind of double-row turret does not know what the consideration is, Su Fan searched all the memory, and did not find a similar design on the earth in his memory, among the three mechanics, one is four turrets, two in the bow and two in the ship, and there is a cannon with a caliber of more than 400+ in the stern, this shape reminds Su Fan of a warship in the book during the Sino-Japanese War.

The level of these three sea mechanics is not outstanding, a salvo of ping pong, blowing up the hill in chaos, quite spectacular, as the main examiner Snape's face is still the same as the dead wife, but several of his invigilators are more satisfied with these candidates, their main guns are ordinary steel guns, but the power is not small.

After a salvo, the three ships withdrew from the combat distance, followed by the wooden boat, which staggered forward, its thin hull seemed to be overturned by the waves raised by the three ships, and the three battleships hurriedly slowed down, not because they were kind, but out of fear of the small wooden ship!

That's right, it's fear, Su Fan stood on top of the signal transmission tower on the bridge very incomprehensibly, looking at the small wooden boat, this signal transmission tower is useless in this shijie, she originally planned to dismantle it, but then she didn't have time, and now it just comes in handy.

The small wooden boat staggered to the combat position, and before it could pose, a huge blue magic array with a diameter of more than ten meters appeared on the defense line at the bow, this magic array was suspended a few meters in front of the bow, and the powerful energy fluctuations made Su Fan's guard radar scream wildly, and the energy in that magic array actually exceeded his own anti-ship missile!

Hoo~boom...A pillar of light shot out of the magic array and landed on the hill, causing a violent explosion, and then the pillar of light swept over the hill that was taken as a target, and wherever the pillar of light swept, the explosion went, as if a bomber was dropping a powerful bomb! The explosion was continuous, and the power of each explosion exceeded that of a 500-pound medium-sized bomb!

No wonder those three battleships were so afraid of this small ship, if this flexible pillar of light swept by, wouldn't the three 25,000-ton battleships directly turn into a pile of garbage on the sea?

Copycat Snape was very satisfied with the performance of the retro sea mechanic, and the face of the dead wife showed a slight smile, and nodded slightly, and after the attack was completed, the retro sea mechanic slowly withdrew from the distance of the battle.
