Hu Zhonghai is the captain of the Peng Zehu, with the rank of colonel, and Xu Dong is at the same level, but Xu Dong has always stayed in the combat unit, and Hu Zhonghai has been a member of the logistics department since he was a soldier.

Hu Bin smiled: "It's nothing to make a fuss about killing a biological battleship, but Captain Hu mentioned in the report that the biological battleship tried to turn away after discovering the Peng Zehu, but it didn't know how to slow down suddenly. At that time, the speed of the Pengzehu was about 2,000 kilometers per second, that is, the biological warship that could easily get rid of the Pengzehu was sent to the door and crashed into the muzzle of Captain Hu's gun as if it were looking for death. ”

Originally, it was impossible to see the report at Hu Bin's level, but when Lu Jian handed over the problem to Hu Bin for study, he deliberately granted Hu Bin the permission to consult the relevant materials.

"Lao Hu, you better talk about the point." Lu Jian was full of doubts, "Don't go around, I'm listening to trouble." ”

"Well, I'll keep it simple." Hu Bin said, "At that time, the distance between the supply ship and the bone mound was about five light seconds, and I checked it, and all the high-speed biological ships that exceeded this distance showed a great reduction in speed. I also asked four destroyer captains to help me do a few tests, and I came to the same conclusion......"

"That's why why you say that acceleration has something to do with the bone mound?" Lu Jian glanced at the bone mound outside the window in shock, and couldn't figure out what connection there was between the two.

"That's right." Hu Bin replied, "Actually, you can figure out the reason as long as you think about it carefully. ”

"Yes, it's useless for you to talk nonsense, tell me what's going on." Xu Dong had been waiting impatiently for a long time.

"It's very simple, the main material of this bone mound is a magnet!" Hu Bin pointed to the porthole and said.

"Magnets?" Lu Jian couldn't have imagined that the answer was actually this, but after thinking about it carefully, it really made sense.

Although the time for mankind to conquer the technology of magnetic engines is very short, the theoretical research is very thorough. To put it simply, magnetic fields are everywhere in the universe, the Earth has a magnetic field, the Sun has a larger magnetic field, and the Milky Way also has a huge magnetic field that covers the entire spiral arm.

Although humans can't feel and can't accurately measure the strength of magnetic fields on large scales, they do exist in the universe.

The magnetic engine uses the ubiquitous magnetic force to generate powerful power, and as for how to use it, it is not up to laymen like Hu Bin and Lu Jian to figure it out.

"Impossible, right?" Xu Dong was still a little skeptical, "Such a big piece? ”

"What is this? It's just a magnet. Hu Bin pursed his lips disdainfully, "Miracles in the universe are everywhere, astronomers two hundred years ago found a super-large diamond with a diameter of more than 4,000 kilometers in the universe, how big is this bone mound?" ”

This thing can really blow! Xu Dong looked incredulous.

"Don't believe me?" Hu Bin didn't see Xu Dong's expression that was wrong, but he could guess, "That diamond star is in the direction of Sagittarius, only fifty light years away from the earth, you can go there and have a look in your lifetime." ”

Astronomers have discovered not only the diamond star, but also a gold star with a gold content of up to 60 percent, and the universe is so big that it is no wonder.

Lu Jian grinned: "This is a good idea, such a big diamond, you don't need to cut it to make a ring, just drill a hole in it and stuff your finger in." ”

Xu Dong's eyes were dark, and he almost fainted: "Commander, now is not the time to talk about this!" ”

"Oh, haha!" Lu Jian, who solved the mystery, was in a good mood, "Tell me what it has to do with it, just celebrate it in advance." ”

Xu Dong was sad, slumped his shoulders and didn't know what else to say.

"Of course." Hu Bin added, "In fact, it is not as exaggerated as you think, it can only be said that this bone mound contains a large number of magnet components, and it cannot be composed of a whole magnet." ”

"Well said, I'll leave this matter to you, and I've found the right person." Lu Jian smiled and patted Hu Bin's shoulder.

The so-called magnet, the accurate name should be natural magnet, the reason why there is a magnet name, is because the magnet is an iron oxide ferric tetroxide, a kind of iron ore.

Although I don't know where the bone man outside the road found such a large magnetite mine, the bone mound in front of him is by no means incomprehensible.

No wonder it's black!

Even if you can't find such a large magnetite mine, it is no problem to make some smaller ones together and form such a scale.

However, the bone mound made of magnetite should not be intentional by the Outer Bone Man, and it was just an accident when it was bumped into by the expeditionary force, so Lu Jian was relieved, the kind of high-speed biological ship that must rely on the magnetic bone mound to increase its speed cannot be a conventional warship among the Outer Bone Man.

Lu Jian could even imagine a group of biological warships drilling around in the asteroid belt, and suddenly found that the speed increased abnormally when flying close to a certain asteroid, which eventually led to the formation of this black bone mound.

After thinking about it deeply, Lu Jian suddenly felt lucky, if the warships of the expeditionary force used a lot of steel, I am afraid that before they get closer, they will be directly sucked by this strange bone mound, and they will end up with a shipwreck...... How many times stronger is the magnetic field of such a large magnet than the earth?

If Hu Bin knew what Lu Jian was thinking, he would have to laugh off his big teeth.

The earth's magnetic field is not weak, when have you ever seen an airplane sucked on the ground and unable to fly? Moreover, magnetism is the basis for the work of the magnetic engine, and the closer it is to the bone mound, the stronger the power of the warships of the expeditionary force will be, and there will never be a situation where it is not strong but weak.

In other words, the strong magnetic field is the power amplifier of the magnetic engine, and it is impossible to attract the battleship, at most it is just to interfere with radio communications.

Solving a knot in his heart, Lu Jian and Hu Bin started a family routine with sunshine, Xu Dong found an opportunity to say hello to Lu Jian and returned to the bridge first, but before he could go far, his personal terminal shook violently one after another.

Xu Dong was taken aback, what happened?

The vibration of the personal terminal represented the urgency of the message, and for more than a second, half of his arm was numb.

Xu Dong hurriedly connected the communication: "I'm Xu Dong." ”

"Report to the Captain, Base Emergency Communications ......"

"Communications from the base?" Xu Dong's spirit was in a trance, what happened? Need to enable such a high level of communication?

At the same time, Lu Jian, who was chatting happily with Hu Bin, also received a communication: "I am Lu Jian. ”

"Commander, emergency communication from the forward base, please rush to the bridge as soon as possible."

Lu Jian frowned: "I'll be there soon." Lao Hu, I'll go first. Xu Dong, wait for me! He took a step forward, striding after Xu Dong at a speed that was not commensurate with his age, and the two of them hurried to the bridge together.
