As Ming Yue'er said, the engine room is a very dangerous place, ten thousand times more dangerous than the center of the nuclear explosion, and even if humans wear a full set of protective clothing, they cannot stay in the engine room. The engine room is strictly forbidden at any time, unless the ship stops working, and the engine room has undergone more than 12 hours of particle neutralization before humans can wear protective suits to carry out repairs and other work.

However, the wreckage of this battleship has been shelved here for 3,000 years, and even if there are more particles in it, after 3,000 years, it will have been almost neutralized. So this time, Liu Nianfeng and the others went in, and there was not much danger, but the search team felt that the target they wanted to search for could not be in the engine room.

"Boom!" With the laser cutting gun finished, the outer protective wall of the engine room was finally cut...... In order to protect the inside of the engine room from particles spilling, the outer protective wall of the entire engine room was more than 50 meters thick, and the search team cut through the entire protective wall for a full five hours before cutting a 50-meter-long tunnel that could be entered.

And after passing through this tunnel, the search team finally saw the scene inside the engine.

"This is a very ridiculous and crappy design, full of all kinds of fallacies, and an extremely bad engine room that increases the chance of engine failure hundreds of times over! I finally understand why the damage rate of battleships 3000 years ago was as high as 1%!! In order to ensure that the search team can quickly carry out work in the engine room, Liu Nianfeng specially transferred some staff who were responsible for the work in the engine room on the Xili.

However, as soon as these staff members entered the engine room, they couldn't help but complain about how bad the engine room design was 3,000 years ago.

Liu Nianfeng's attention was not on these complaints at all, he searched the wall, found a controller, and then forcibly disassembled the controller, took out the memory chip inside, and finally glanced at the number of the memory chip.

"That's right! Bismarck, she's here! After seeing the number of this memory chip clearly, Liu Nianfeng immediately said with great certainty.

"Admiral? What did you find? Mingyue'er beside her asked curiously.

"You look at the number of this memory chip, and then compare the number of the memory chip we got, and you will understand why I said that!" Liu Nianfeng handed the memory chip to Ming Yue'er, and Ming Yue'er glanced at it, and her face showed a clear expression, because the difference between the number on this memory chip and the number on the memory chip that Liu Nianfeng got before was only five digits.

This means that these two memory chips are produced at the same time, and the memory chips produced at the same time are often used in the same position of the same battleship, in other words, the previous memory chip is the chip in this engine room.

It was Bismarck, who fled here, who forcibly took out the memory chip, recorded his own information, and threw it outside to ask for help!

Liu Nianfeng's discovery made everyone feel excited, and they felt that maybe Bismarck was really here.

The problem is that despite the size of the engine room, most of the space is used for antimatter engines, and there is only one aisle around the perimeter where humans can stay.

The aisle was quickly searched several times, but no trace of the existence of the frozen survival pod was found.

"Damn! Where did this Bismarck hide? Could it be that she still hid in the engine? Mingyue'er on the side muttered, and this sound immediately made Liu Nianfeng, who was originally a little dazed, wake up, and directly ordered the dismantling of the engine, completely dismantling the engine.

Although the search team felt incomprehensible to Liu Nianfeng's order, the engine room could not survive, if it entered the inside of the engine, it was estimated that there would be no ashes burned, how could someone get into the engine?

But Liu Nianfeng's words are holy decrees, and the search team can only continue to dismantle them.

However, the engine cannot be violently disassembled, although 3000 years have passed, there is definitely still residual antimatter fuel in the engine, once some incorrect operation detonates these antimatter fuels, everyone present will not want to leave alive.

Therefore, the search team was very careful to dismantle, and did not dare to use violent dismantling methods such as laser guns, and could only forcibly dismantle it by physical means, coupled with the lack of professional demolition equipment on the Yuli, so the speed of dismantling was quite slow. Ten hours had passed, and the engine had just been dismantled by 1/10th.

"What is this?" When a large piece of protective armor was removed, revealing a huge ball inside, Liu Nianfeng asked with some curiosity.

"Back to the Admiral, this is the engine's cooling tank, which contains liquefied nitrogen 87 that can help the engine cool down quickly!" A staff member who was familiar with the engine explained to Liu Nianfeng that like all engines, the antimatter engine must of course have its own cooling system.

It's just that the water used in ordinary engines obviously can't be used for antimatter engines, and even low-temperature objects such as liquefied nitrogen are difficult to quickly cool down antimatter engines with temperatures of up to millions of degrees Celsius.

This liquefied nitrogen 87 is an isotope of nitrogen, which has a cooling ability 10,000 times better than ordinary liquefied nitrogen, and has been widely used as a cooling liquid for engines after it was developed, even after 3,000 years, the cooling material used on the Yutachi is still liquefied nitrogen 87.

"Cool down at high speed!" This name made Liu Nianfeng's mind instantly clear, yes, Liu Nianfeng found that he had been falling into a misunderstanding.

Liu Nianfeng has always believed that if Bismarck wants to live for 3,000 years, he must use a cryogenic life support chamber to do so.

It wasn't until this cooling tank filled with liquefied nitrogen 87 appeared that Liu Nianfeng suddenly realized that Bismarck didn't necessarily have to use a cryogenic life support cabin, as long as she jumped into this liquefied nitrogen 87, she could also use the amazing freezing ability of liquefied nitrogen 87 to freeze herself and wait for future generations to save herself.

It's just that Bismarck couldn't have imagined that the descendants who came to save him would be human beings 3,000 years later!

"Don't deal with the engine anymore, open this cooling tank for me!" Liu Nianfeng once again gave a new order, so the staff quickly gave up their work and began to deal with this cooling tank with all their might.

Compared with dismantling the engine, opening a cooling tank is a very simple and pleasant job, and soon the entire cooling tank is opened, and at the same time the drain is also opened, and the liquid nitrogen 87 that has been sealed in the cooling tank for 3,000 years begins to slowly flow out of the human irrigation...... Because of the long-term exposure to the vacuum, and the lack of perseverance around, the temperature of the cooling tank at this time is already more than 100 degrees below zero, so the liquid nitrogen 87 that flows out only emits a little gas smoke, and does not quickly evaporate into gas, but still flows in the engine room in the form of liquid.

In order to speed up the discharge of the liquid in the cooling tank, Liu Nianfeng ordered someone to open an opening the bottom of the cooling tank the size of a human body, so that the liquid nitrogen in the cooling tank flowed out quickly, and soon all of it was empty, exposing the tank inside!

"Someone! There's really someone in there! A staff member with sharp eyes screamed for the first time, and under the arrangement of Liu Nianfeng, several other staff members rushed into the cooling tank as soon as possible and lifted out the person who had been frozen for 3,000 years.

When this person was carried out, Liu Nianfeng glanced at it slightly, but the other party's body was completely covered by frost, like ice and snow, and he couldn't see his original face clearly. But the clothes on his body are still intact.

"Quick! Hurry up and get into the medical pod! Liu Nianfeng didn't dare to expose this person in a vacuum for too long, otherwise she would not die in liquefied nitrogen, but would die under the air, which is something that Liu Nianfeng wanted to cry without tears.

Therefore, Liu Nianfeng had already prepared the most advanced medical cabin, put it in the engine room, and when this person was discharged as soon as he was discharged, he was directly sent into the medical cabin.

"Report! A life signal has been detected! We detected this person's vital signal! She's alive! The man is still alive!!! One of the staff members in charge of the medical module suddenly jumped up excitedly and said in a way that bordered on incoherence.

For this medical worker, this discovery is shocking, and it is enough to change the whole world, a human can go through 3,000 years and still not die, and still have his own life signal...... I believe that once this story is announced, I am afraid that it will cause the entire human world to boil, and I may even be able to win the Royal Medical Award of the Empire, the most famous award in the Human Empire.

"You go and discuss with Admiral Chen Shihan...... When we return to Heavenly Court, everyone on this battleship will be locked up for me, and then go back to Ancestral Dragon Star with us! Seeing this scene, Liu Nianfeng didn't say anything at the time, and there was a smile on his face, but he secretly said to Ming Yue'er.

Some of these staff members were the staff brought by Liu Nianfeng from the Ancestral Dragon Star, and the other part was borrowed from Chen Shihan from the Heavenly Court Star, after all, the battle cruiser and the destroyer were still very different, and the Xili destroyer still needed some special staff.

But this discovery, it is impossible for Liu Nian Feng to go out to the public no matter what, so he can only grieve these unlucky staff members and go to the ancestral dragon star where birds don't with Liu Nian Feng.

At the beginning, these staff members were naturally resentful and dissatisfied, and forcibly sent them to the Ancestral Dragon Star in a confined way, which would make everyone unhappy.

But after a few years, all these unhappiness and dissatisfaction will disappear, and they will be proud of every day they spend on the ancestral dragon star!
