Because protective clothing alone is not enough.
There must also be a survival backpack integrating constant temperature, constant pressure, oxygen supply, communication, and battery, as well as a protective helmet.
This is strictly controlled by the dungeon.
As long as you grasp the hurdle of going out, it is enough.
Everyone sat facing each other, the car started and drove into the elevator.
"One click, car synchronization!"
"Twice, local area broadcast!"
"Three times, private frequency band!"
"The display screen on the hand can provide real-time feedback information, including navigation, communication, oxygen reserves, physical signs, etc."
"..."
He Shuli explained patiently.
Chu Xuan naturally knew this, but he didn't disappoint his good intentions.
It's time to pretend to be cute!
15 minutes later.
【drop!Reach the ground! 】
click!
The elevator door opened, and in an instant, the temperature outside the car dropped sharply, but I didn't feel anything inside the car, not even wearing a helmet.
Outside the car window, on the elevator display.
Temperature: -85.
Oxygen content: 16%.
It is already a difficult environment for human beings to live in, that is, around the planetary engine, the temperature will be a little higher.
In the rest of the places, it was already minus one hundred degrees.
Huhu~
The cold wind brings "white snow".
Obviously, not exactly snow, mostly solid carbon dioxide.
When it is far away from the solar system, at minus 200 degrees, oxygen and nitrogen will also become solid, and then.
The sky will become extremely clear.
hum~
The engineering vehicle started and drove out. This is the flood embankment.
The capital is tens of meters above sea level.
The previous tsunami caused the sea level to soar by 300 meters. Therefore, the planetary engine has a circle of flood barriers.
The average height is 300 meters and the width reaches [-] meters.
The ore carrier was parked at the top of the flood embankment.
window.
Chu Xuan looked out the window, the world of ice and snow.
Construction vehicles are also driving on the main road.
Tens of meters long, with a limit load of [-] tons, heavy industrial metal style.
Mechanical aesthetics!
Quite good looking!
The more you open.
The terrain is slowly descending, and the ice around the flood embankment has almost been dug up and burned, and now the stones are being dug.
Sent to fusion day and night.
The engineering vehicle turned a corner, and in an instant, the planetary engine came into view.
Big Mac!
The movie screen is too small to fully reflect it.
Really seeing it is even more shocking!
Just the height is more than ten kilometers.
It surpassed the cloud layer and approached the limit of the flight altitude of the passenger plane.
It is indeed a thing that human beings have exhausted all their resources to build.
As far as the steel required for a planetary engine is concerned... Chu Xuan can only say that it is too expensive.
How was this earth created?
Where did so many steel resources come from?
When watching movies, everyone's main focus is some "unscientific".
such as.
The sun cannot age rapidly.
A planetary engine can't move the earth.
Except around the planetary engine, it is impossible to have heavy snowfall elsewhere.
Gravitational slingshot, there should be no danger.
......
However, few people pay attention, where are the resources to build so many engines?
Simple example.
Before the catastrophe, Huaxia produced more than one billion tons of steel a year, ranking first in the world.
And how much does a planetary engine weigh?
---Trillions of tons!
The steering engine is heavier.
Even if the iron ore ten kilometers below the surface is bald, it will not be able to produce so many raw materials.
One engine, according to the annual output before the catastrophe.
It takes Huaxia Iron and Steel Enterprises to produce for hundreds of years.
And such a big guy.
There are ten thousand seats in the world.
unscientific?
Do not!
This is science.
The end point of heavy nuclear fusion is iron, that is to say, a planetary engine is a steelmaking furnace.
Elements whose ordinal number is lower than iron can be fused into iron and steel, such as stone.
Except for the original engine group, it was built with all resources.
Most of the remaining engine building materials are made of such fusion.
Chapter 19
As the engineering vehicle advances.
The landscape gradually becomes monotonous.
The endless plains do not require a driveway at all, and the ground is a thick layer of frozen ice, which is very hard.
Chu Xuan also looked away.
After looking at it for a long time, there is really nothing to see.
Miss the environment before the cataclysm.
Even in the desert, there will be some vitality, but here, there is only cold and dead silence.
"This classmate, is it your first time to come out?" Someone beside him greeted him.
Chu Xuan nodded: "Yes."
"Changed major?"
"No!"
"Then what are you doing at the observation base?"
"Knowledge."
"..."
In a few words, you can find out what you want, and no one asks any more questions, just think that Chu Xuan came up for a walk because of his connections.
See this situation.
How could He Shuli not know what his students thought.
With a slight smile, he opened the mouth and said:
"Although it is a minor, in terms of level, there may not be anyone among you who can match it, so don't convince me."
"He has already obtained a level A1 degree in astrophysics in advance."
"Officially certified by the United Government Talent Administrators Council."
As soon as this word comes out.
There was an uproar.
"what?"
"A1 minor?"
"New certification?"
"..."
More than a dozen people looked at Chu Xuan intently. Strictly speaking, although they are majors, none of them have graduated yet.
This time I went to the astronomical observation base.
Only then will the defense begin!
Chu Xuan actually walked in front of them, his first reaction was to leave the relationship.
Do not!
After reacting, he shook his head slightly, telling them rationally that it was impossible.
suddenly.
Someone remembered that they had vaguely heard of a great man before, and recalled some information they had learned.
Could it be... is it him?
At this moment, everyone looked at Chu Xuan differently.
Previously, I thought it was a car rubbish.
Now, people actually took a step ahead.
Everyone has a degree, but I am still waiting to graduate.
"Student Chu, is it difficult to defend against the new rules?" the classmate who chatted with Chu Xuan just now asked hurriedly.
"Quite simple."
