Rosen and Itrak spent a few days in Birch City.

The two of them bought helmets and stuffed ears.

Just in case he is attacked again by the monster that flies to find the people of Si Country, which can emit infrasound waves.

And Zheng Ying also took advantage of the dull "night" in the dense forest to start laying various detectors, in case someone came, and she didn't know it yet.

The makeshift silos, which were made by buying their own metal welding, were ready.

It's all rudimentary, and I can't bear to look at it directly.

First of all, the propeller is welded out of a one-centimeter-thick steel plate, with a double-layer "V" shaped anti-expansion structure.

Soon Zheng Ying began to sand the thruster engine, as if he had memorized all the mechanical blueprints in his head, and the forging furnace and steelmaking furnace for melting steel had already been completed.

The mountain stream a hundred kilometers away from the northern border of Qingluo Country has become his private research base.

One person lights a fire, one person goes to chop wood to burn charcoal, and then grinds and crushes the charcoal to make it into a heating dye that can be used as a refining metal, that is, coke.

He's been doing this since he entered here and settled in.

Every day, when I go out to eat, drink, and Lazar, I repair the flat land at the bottom of the mountain stream and valley, and get some suggested machinery from the outside for deep processing and utilization.

There were rocks everywhere that no one cared for, and the hammer had broken them, and the pavement could be paved with stones and stone powder.

Everyone in the real world has to work from 9 to 5 every day for that little paycheck.

Zheng Ying is like a reclusive outsider, spending all her time outside of rest to build her own hiding place.

The valley bottom in the mountain stream is dozens of kilometers long, and two kilometers from the mountain stream into the interior, it is the stone powder road paved by Zheng Ying alone!

This is used as a foundation foundation, because the scaffolding that looks only a few tens of meters high is not a joke, he really intends to get a thruster to push himself into the sky.

It is probably that a person has been in the world for a long time and has forgotten about the world, or he feels that the world has also forgotten his existence.

So I will nag to myself: "The whole world doesn't love me, then I'll go and go to a place that loves me." Then he looked up at the deep blue of the night sky, praying that one of the stars in the sky would be able to accommodate his wayward life.

The casting of refined metals is also very simple, a large number of broken scrap iron, bought from the outside at the price of scrap products, welding that should be welded, forging that should be forged.

The stones in the surrounding mountains were dug deep and the sand could be seen.

It's much easier to have sand, because it can be purified and its essence can be used as a fire-resistant and high-temperature resistant material.

After building the "stove" and the manual mechanical boom, the steelmaking furnace like a small car was hoisted, and then the sand casting began.

He wanted turbine engines early, because it was based on ancient technology, probably more than a hundred years ago, when rocket technology was just emerging, and there was a record of using kerosene as propeller fuel.

So through calculations and evaluations, Zheng Ying feels that this is the easiest thing to find on the market.

The large oil tank that was welded before stored twenty tons of kerosene.

Of course, this is not the kind of first-class aviation kerosene, but ordinary civilian lamp kerosene, looking back a few decades, Cheongla country had kerosene lamps, horseshoe lamps in the past.

Now, Zheng Ying wants to use it as a thruster dye to push a homemade rocket like a cupola cannon!

This sounds ridiculous, but after all, he is a former scientific advisor from the third base, and he has this name, and naturally he also has this brain, and the rest just don't be lazy and get started.

Perhaps many people in the world want to have a scientific and technological mind like Zheng Ying, and then make a fortune, but for him, his past life experience has affected his personality.

Originally, Zheng Ying was born a long time ago, and his relatives never appeared.

Zhang Yao belongs to the third base, which belongs to the Qingluo base in Qingluo country, and is the boss of the sub-base here.

During this period, he arranged for someone to send Zheng Ying to the countryside to be raised by a designated family.

It seems that the family's temperament is too unsatisfactory, and they treat Zheng Ying like an animal.

Zheng Ying didn't know this, it was arranged by Zhang Yao.

When the Qingluo base was blown up, Zhang Yao arranged for someone to release the news that a secret base had been attacked, which was published in the newspaper and became news.

He said to Luke privately: "I thought that by domesticating a person from birth, he could become a kind of submissiveness, and when we gave him some help and treated him well, he could be obediently used by me!" ”

Luke shook his head with a wry smile, because the facts showed that Zheng Ying did not give up thinking because of this! He wants to struggle, he can be alone, but he must not live uncomfortably.

That's right, Zheng Ying ran away, Luke felt that it was understandable, but Zhang Yao was puzzled.

In contrast, in the entire Qingluo base, only Luo Aiguo is the original slippery person, he doesn't care who Zheng Ying is, as long as he is gentle, he is willing to accept friendly things, instead of yelling all day long, yelling and drinking, and a bunch of rules that make people feel that they have nothing to do with what they have to do at hand!

What Zheng Ying wants to turn over the sand to cast is one axis, or three!

One of them is the main bearing of a turbine internal combustion engine, and the mold cast is one centimeter larger than the actual design! After the condensation, he had to use a sander with his bare hands to polish it little by little until it was the same size as the design drawing!

Zheng Ying didn't deal with the accuracy here, he felt that as long as he "could use it" and "could hold up enough to send himself to the sky", he would be fine.

Two other shafts, one for the turbocharger and one for the gyroscope!

Now he sensed a bad situation, and this conservative plan was forced to move forward.

Because someone began to break into the country of Fei Xunren, Zheng Ying also knew that it was Ittak and Rosen, and the detection equipment clearly recorded the infrared images of the two of them coming to the dense forest, including recording the voice dialogue between the two of them, and what happened at that time.

"This monster must have attacked them!" Zheng Ying looked at the burnt wooden stakes, a few days ago he used the car of the resonance coupling device to emit the resonance frequency and shatter this monster!

I didn't meet it, maybe God helped, luckily, he thought so.

As for those dark shadows, the nights like people, Zheng Ying didn't know at all.

Ittak took Lawson to raise him in White Birch City for a few days, wrote a detailed mission report, and passed it back to the Qingluo base in ancient Morse code.

After Zhang Yao saw it, he asked Liang Xue very strangely, Liang Xue said that those dark nights, could it be some kind of troublemaker? Trying to wait for Zheng Ying's research to succeed somewhere, steal it or rob it directly?

As the boss of the Qingluo base, Zhang Yao didn't say too much about Zheng Ying's location, it's not that he can't directly enter the country of Feixun Rensi, with the support of the third base, he can go anywhere in the world!

But there is a place of right and wrong, and it is not good that the managers of the ordinary human world will interfere with it, so they came up with a way to launch a super soldier sneak attack with You Fengchu, which can be regarded as a bitter plan for helplessness.

Zheng Ying didn't know about the bitter meat plan, it just so happened that he hadn't turned on the radio equipment in the past few days, and the news and reports of the human world had nothing to do with him.

Infrasonic injured Rosen, in addition to being on guard, Itak was accompanying him, waiting for the mission report to be sent, and a few days later, Rosen's body also recovered, and the two of them planned to enter the country of Feixun again, the territory of death!

Now that they know they've hit a wall on their first visit, they'll be coming back soon.

Zheng Ying realized this, so she hurriedly fled, shifted her position, or saw if she could speed up the progress of leaving in the past few days.

Originally, I was going to concentrate on nuclear energy or quantum science here.

But it seems that there is no time!

In the second-generation drill designed by Zheng Ying, the gyroscope is not needed, it is a stabilization device, but he does not plan to use avionics systems and electromagnetics.

What he is going to use is a black technology that does not require electricity, fuel, or so-called engine power, and can soar into the sky!

It's something that no one in the world can make, and it's like it's more difficult than building a perpetual motion machine.

The conservation of energy, the relative distance from something in a decent way, is to leave a part of the work done.

Therefore, rockets will always have a first-stage booster and a second-stage booster, continuous acceleration, and constantly throw away their own weight.

In Zheng Ying's heart, this is too backward.

He doesn't want to be backward, he doesn't want his beloved motherland to fall behind, and he doesn't want this world, this human world, to be backward.

But no matter how smart Zheng Ying is, he is still a person and a child.

He has not undergone training to strengthen psychological construction, nor does he have the psychological quality of being calm and calm in the face of problems.

He didn't break down now, he was already very powerful, at least for a sixteen-year-old.

Hysterical, neurotic, like a fool talking to himself, but still sober in the science and technology mind.

That's the most valuable thing in his body, and it's what he's capable of!

It's like a woman who is mentally ill and crazy with everyone, but once she cares about her children and the things she cares about the most, she will be extremely sober and feel a feeling.

Zheng Ying has no children, let alone a mother, and he doesn't have the relatives who make him feel painful and want to give up anything to protect, even the father who has raised him for many years.

Because his father always beats and scolds himself, he has hated it since he was a child, but he knows that the young and the old are orderly, there is a difference between respect and inferiority, and filial piety comes first! So those beatings and scoldings for him, the pretense that has acquiesced to it can be tolerated.

But from the moment I entered the third base, I knew that I was raised by others, and the people who raised me were not my relatives...... At that time, he was already shaken.

"They raised me, just to beat me and scold me? If my biological parents knew that their adoptive father's family treated their son like this, how distressed would my parents be? People's hearts are flesh and blood, since they don't treat me as a precious son, why do I still have the heart of the Virgin, to shamelessly commit cheapness, what kind of nurturing grace? ”

Zheng Ying secretly kept a sum of money, and when he ran away before, the owner of a hotel, he gave him a few million, saying that half of it was for the family who had raised him.

If the hotel owner changes to stealing, Zheng Ying said that he has more money to settle accounts with him! The premise is that the money can be sent back when the news of his death is discovered.

Because it's a psychological arrangement!

If you die, and an unknown person can know the news of his death, it means that his plan has succeeded!

Many people know themselves that they have died, or their scientific research equipment has been wrecked, or they have been killed by the armed forces of the real world.

If you are caught by the third base, then this matter is over! Because the third base also has two options, if you kill yourself, you will give a sum of money to the family that raises you, after all, it is arranged by the third base.

If he doesn't die, he will continue to work as a scientific researcher, and I don't know if it's a scientific advisor, but that's it, as long as I live, I also have time to go back and see the family that raised me.

"Am I being disliked?" Zheng Ying looked at herself in the mirror, smirked, raised her hand and touched the side of her mouth, she was about to grow a beard.

……

The sand casting went smoothly, and the complete "equipment" was very simple, but it could be used.

Perfect design drawings, and brilliant brains, albeit crudely precise.

But Zheng Ying feels that this is very fulfilling, the sense of accomplishment is not for people to see, after showing it to many people, it is for many people to shout and cheer for themselves, it is they who can do it, "I can", then it is very fulfilling.

Silently compare with the world, you are very strong!

Comparison is not a good thing, as the saying goes, people are more popular than people, but Zheng Ying is very optimistic: I am not enough to compare, more than enough!

……

In the evening, Itak and Rosen, driving their three-wheeled motorcycles towards the border, said that they should fight quickly, the sooner the better, because the more time is delayed, the longer they stay in this place of right and wrong, the greater the danger!

But Zheng Ying is also ready, the turbine internal combustion engine, attached turbocharging device, injected seven tons of kerosene, with a large afterburner supercharger, the kerosene will enter the internal combustion engine in the form of high-pressure spray, and the blades will spray the ignited kerosene gas mist to the earth at high pressure and speed, generating a huge thrust and pushing this rocket into the sky!

"Don't make a mistake! Fly as you please! Zheng Ying smiled.

The rocket is there, to the sky? Kerosene for spacecraft or personnel cockpits.

In fact, he didn't plan to leave now at all, but after thinking about it, he felt that this was a big deal.

If you launch a rocket out of the atmosphere, or higher, and the parabola falls, who knows if there will be a vehicle sent into space?

Because he is smart enough, even if the sky detection department does not find the aircraft flying into space, he will think that it is "Zheng Ying's aircraft" and may be "so advanced that no one can detect it"!

He smiled arbitrarily, drove the off-road vehicle, dragged a welded body behind him, pulled a bunch of experimental equipment and data drawings, and quickly headed towards the depths of the mountain stream.

And the pile of things in place, the remaining kerosene will blow it up after the rocket takes off, and the timing device will blow it up! At the same time, it will also erase the route you left off!

Because in the entire mountain stream, on the cliffs on both sides of the valley floor along the way, Zheng Ying made the remaining gasoline and diesel into small gas bombs! After he leaves, he will blow up this deep mountain stream and valley, and continue to move deeper towards this no-man's land known as the "Death Territory".

Zheng Ying feels that as long as you have your brain, you can start from scratch wherever you go, the earth has given you all the things you need under your feet, as long as you understand science, building a private scientific research base is very simple, it's just a matter of time.
