Playing hide and seek with Da Liu and them went well, even if they hid deeper, Mei Zheren could dig them out.

He plans to find another one out immediately, on peek-a-boo, which is his strength, he can change various identities, and he can also shuttle between different dimensions.

Under the nose of the old squad leader, do you still want to stay on the Qinglong and not leave? There are no doors!

Give me back to Shui Lan to watch my home, and this place will become the throne of King Pyro.

In fact, the crew also understood that once the personnel of the Star Kingdom boarded the Blue Dragon, they would definitely be brought back, and the clues were left so that people could find them.

As for why he did this, it was probably to express a belief in coexistence with the Blue Dragon.

Mei Zheren can understand the crew's reluctance to give up the Qinglong, and people always want to pin their will on the most familiar and beloved things.

He opened the space log again, glanced at the directory hurriedly, and found that there was a large video file that was very conspicuous, and clicked on it casually.

As soon as the video played, Mei Zheren paused, because the picture was facing the control console of the Blue Dragon, and the display screen projected the space outside, and the three spaceships were approaching the orbit of the Blue Dragon.

The silicon-based people still remember the Qinglong, which should be after Da Liu fell asleep.

Zhang Beihai is operating nervously and orderly, and you can see that the picture is a little off-axis, which is the Qinglong changing orbit.

Then, the speed at which the three spaceships became larger was accelerating, and Mei Zheren's brows trembled, did Zhang Beihai really want to collide?

Really, he opened the plaintext communication: "This is the Qinglong space station, I am Zhang Beihai, the navigator of the Qinglong, now you only have two choices, either change orbit and avoid, or everyone hug, Xiao Luo, has the bomb hatch been opened?" ”

Luo Ji's voice came: "The setup has been completed, connected to the induction system of the Qinglong, whether it is vibration or heat or what, as long as they do it, the kinetic energy bullet will go down." ”

Zhang Beihai didn't react when he heard this, but continued to shout loudly towards the receiver: "Listen to the spaceship on the other side, now my ship is ordered to hit your ship, please get ready, I'm going to speed up." ”

After speaking, Zhang Beihai adjusted the output of the Hall thruster to the maximum, and the picture began to shake, which was caused by vector jetting.

The three Aba-national spaceships in the holographic screen panicked, and it can be seen from the screen that their tails and sideways also began to spray light blue flames.

This is the other party's orbit change engine turned on, and not only that, not far from the blue flame, some white fog also shot out, which is even used for the jet steering of the emergency orbit change.

But the Qinglong did not show weakness, and did not accept it when it saw goodness, but accelerated straight forward.

Seeing that the collision was imminent, the silicon-based people also went crazy, and all the emergency jets were turned on to the maximum, and more than a dozen clouds of fog were about to envelop the spaceship.

At this moment, Zhang Beihai suddenly raised his hand, his fingers opened, and he retracted it one by one, is this countdown?

Finally, when he harvested his fist, the three spaceships avoided colliding with the Blue Dragon, but they were forced to squeeze together by the Blue Dragon, and the nearest place might not be more than five meters.

At this time, the anomaly was abrupt, and the Qinglong was supposed to be a jet-propelled brake thruster, but suddenly a water arrow spewed out.

Mei Zheren finally knew why there was so little water stored in the space station, and they were used for it.

There was already an inertial speed of more than ten kilometers per second, but it was accelerated by the ejector, and the water was no longer a weak liquid, but turned into a steel knife to scrape bones.

The three ships of the country of Aba's country were cut open by this water arrow, as easily and neatly as cutting a cake.

The cut didn't cause an explosion, but silently split the ship in half, avoiding all the parts that would cause the explosion.

A good and accurate scalpel, this is a technique only available to top surgeons, no need to guess, it must have been done by Liu Yang.

She is both a hygienist on the space station, a biologist, and a logistics officer.

Only Liu Yang has such a clever knife technique, and he is violent with one sword, without losing the slightest.

The three enemy ships were calculated by Zhang Beihai in this way, and he laughed out loud, perhaps laughing too quickly, a little out of breath, and coughing violently.

Luo Ji and Liu Yang came over, and Luo Ji also showed off: "Lao Zhang, is my modified waterjet good?" ”

Zhang Beihai did not respond to him, but coughed more and more urgently, and finally spit out a mouthful of red mist.

The red mist sprayed directly at the console, and Liu Yang quickly opened the suction device and sucked the red mist away.

After finishing this, Liu Yang turned his head to care about Zhang Beihai: "How about it, can you still withstand it?" ”

Zhang Beihai waved his hand, bent down dejectedly, and sat on the floor like this.

Liu Yang took out a cardiotonic injection, but was stopped by Zhang Beihai: "Don't waste it, keep you." ”

He almost gritted his teeth and spit out a few words, his usual tough style did not allow him to survive like an old man, even if he died, he had to freeze.

Luo Ji's voice trembled a little: "Lao Zhang, hold on." ”

Zhang Beihai shook his head slightly, exhaled and inhaled hard, his breath was long and thick, and some blood stars splashed out of his nostrils.

Fortunately, the space station is a microgravity environment, and these vapors are immediately sucked away by the suction system, otherwise it is really dangerous.

Zhang Beihai took a breath before he said to Luo Ji: "I'm not afraid of Liu Yang, don't look at her as a woman, but she is calmer than you, according to the current level of health, in the end, it must be you alone to guard the Qinglong, remember, the heart must be hard, the hands must be ruthless, what we hold in our hands is the fate of Shui Lan." ”

Luo Ji forcibly held back his tears and nodded fiercely.

Zhang Beihai laughed when he saw it, and he looked at Liu Yang again: "I can't stand it, I'm going to sleep too, remember to supplement the working fluid, plus I can make up enough for three orbit changes." ”

After finishing speaking, there was a long breath, and Zhang Beihai remembered something again.

"Don't put me and Da Liu together, Lao Tzu has been pressed by him, and he was half a point short when he took the stationmaster's exam, and he was depressed when he thought about it."

"I finally won him this time, I lasted a year longer than him, but I can't stand it anymore, how can it be a damn melanoma, and I don't smoke."

Thinking that he was not angry, Zhang Beihai waved his hand, but stopped halfway through the wave, put his hand in front of him, but still couldn't see it.

"Black tumors of liver origin, caused by radiation, induce hepatic encephalopathy, complications can cause vision weakness and even blindness."

Liu Yang was very calm and said Zhang Beihai's condition flatly, but it didn't hit him.

Zhang Beihai put down his hand, folded it on his abdomen, and slowly lay down: "Come on, give me a needle, let me sleep well." ”

Liu Yang's hand was very steady and fast, she quickly picked up a jet syringe and gently ticked the launch button in Zhang Beihai's heart.

Zhang Beihai's breathing soon changed from rapid to even, and then slowly became faint until it subsided.

This time, Zhang Beihai fell asleep completely, and his whole body no longer trembled because of the pain, and after carrying it for decades, he could finally relax.

Liu Yang neatly sorted out Zhang Beihai's remains, and spit out softly: "Come with me, there are some things you have to learn, this is the last chance, next time you have to get started directly." ”

Luo Ji endured the pain and nodded, took a cart, carried Zhang Beihai to it, and pushed it to the feeding area.

This is the end of the video, but the plot continues.

The propulsion method used in the orbit change of Qinglong is Hall propulsion, which is to jet the ion stream backward to bring power, this engine does not need fuel, the ion flow is the electron flow, and the micro fusion reactor of the space station is its energy supply device.

However, the power of the Hall thruster is never large enough, and the process of starting to full speed is very slow, which brings a constraint, and the speed reduction is just as slow.

The space station is large and subject to strong gravitational forces, and there is no way to achieve it in one step with complete precision by controlling the Hall thruster switch and thrust revers.

In this way, after each orbit change, a power is needed to brake, which is the brake thruster.

Only by starting the brake thruster to slow down the braking brake can the orbit change be completed with the Hall thruster.

The orbital altitude of the space station is not large, and the orbit adjustment must be completed once a year to prevent the space station from sliding into low-earth orbit.

If left unattended for a long time, the space station is even at risk of crashing into the atmosphere.

This is also the reason why when the submarine flew up, everyone was shocked to find that the Qinglong was still safe and sound.

And every time there is a change of orbit, there is a need to advance the working fluid, which is anything that can be made into fuel.

Electrolysis of water is a major source, but the combustion value of the hydrogen-oxygen mixture is not enough, and the particle flow injected is not strong enough.

The human body contains a lot of carbon, oxygen, and water, which can be used as a source of working fluid, which sounds creepy, but it reflects the fearlessness and sacrifice of astronauts.

Matter cannot be created out of nothing, although there is a large amount of supplies on the space station, no matter how Liu Yang calculates, no matter how efficient the production of synthetic food is, it can only last for twelve years.

And time is the most precious thing that Liu Yang must strive for.

Every little time that drags on increases the hope of human beings to survive or even turn defeat into victory.

With the Blue Dragon in the sky, it can give the humans on the water blue time to breathe and prepare.

Therefore, the materials on any space station are irreplaceable.

From the very beginning of the space station's declaration of death with the enemy, the four of them began to comprehensively collect and classify the materials on the ship, and all the things that could not be eaten and could be turned into working fluids by physical, chemical, and biological methods were used.

Even the quilts that everyone covers are no exception, and it is better to use the electrical energy of the fusion reactor to adjust the temperature, but also to prepare more materials.

In the end, Da Liu pushed the plan, not to mention, he was the first one, and he went to be a propellant after falling asleep.

Because he calculated that if all four of them agreed to this plan, they would be able to survive for just the same time as the consumption of food.

In the end, the remaining person was about to convert all the food into working fluid at once, just in time for the Blue Dragon to fly into a high orbit.

What does this mean? It means it's dawn.

Da Liu also grasped the key point of the fiery red storm.

At first, he didn't know that the silicons were afraid of the fiery red storm, and he was reluctant to turn on the fusion reactor when he found that the enemy's energy supply was unsustainable.

If you don't take a shortcut, you have to take a long road, there must be a ghost!

After comparison, Da Liu and the others finally found that the enemy was afraid of electromagnetic storms, especially gamma rays, because their strength was never close to the South Ice Pole.

If they are afraid of nuclear fusion and do not go to the South Ice, it means that they are afraid of fiery radiation.

Because there is a large ozone hole over the Arctic continent, the radiation is much stronger than in other parts of the water.

They didn't think of using Starlink to channel fiery red radiation into the water blue atmosphere, because they were not Mei Zheren, and they couldn't fight each other in the network.

They felt that once the fiery storm came, the opponent's electromagnetic suppression would be weakened, and maybe then the human race would turn over.

These are all recorded in Zhang Beihai's miscellaneous notes, he is at the helm, and of course he knows everything about advancing the orbit change.

Mei Zheren browsed in the main brain as he came to the power cabin.

He easily used the infrared scan to find Zhang Beihai, this kid was hiding in the crystal center of the Hall jet device, and he really used himself as a diamond.

took out Zhang Beihai and replaced it with an ordinary crystal oscillator, Mei Zheren gently put him in the palm of his hand: "Did you kid come here to the town engine?" ”
