Earth Invasion

Chapter 1 Winter Vacation in the 25th Century

The fire is burning.

Bullets are flying.

He and she looked at each other affectionately, the beating flame reflected on their blue and green eyes, reflecting the spark of love.

"Honey, you have to live, and you have my share." He gently kissed her lips, which were cold and soft.

She bit her lips tightly, trying not to cry, and then nodded vigorously.The enemy's footsteps, shouts, and gunshots outside the window are getting closer.

It's the last moment.

He laughed, picked up the pistol, and rushed out without looking back!In an instant, gunshots rang out.She lowered her head, strode forward vigorously, and fled to the exit.

Then, Zhang Mai woke up.Because he heard a bang, and then sat down on his own bed with his buttocks, almost pressing his ankle.

"Damn, the disturbing dream early in the morning. Be gentle, it broke my ankle." Stretching out his arm from under the quilt, he yawned loudly, and Zhang Mai reached out and rubbed the gum in the corner of his eyes , looking sleepily at the upper bunk next to the bed wearing shoes.

"Fuck, it's still early in the morning? What time is it? It was too high last night, right? No one thinks of timing the lights. Get up, we're going to be late! Get up, alas! Get up With that said, the upper bunk picked up a caliper and knocked on the bunk.The remaining four people in the entire nest also got up from the bed cursingly, brushing their hair like a bird's nest with their hands one by one, either wearing shorts or jumping off with bare buttocks, and then lined up to go to the toilet .

"Fuck, I'm finally going back to the ground today. It's not fun to poop in these places." A big shirtless man came out of the bathroom with his belt in his hand, and said while lifting the heels of his shoes.

"Damn it, our dormitory is in the residential area. The satellite's rotation radius is 51000 meters, and the rotation speed is about 20 meters per second. After deducting the damping, the gravitational acceleration we bear is exactly 9 Newtons per kilogram, you old man Could it be that Ke has a constant anti-inertia spell that prevents you from having poop?" A roommate retorted mercilessly in the bathroom to the big man known as Old Ke.

"Understand the spirit! I'm called returning home like an arrow!" Lao Ke didn't blush at his roommate's complaints, and still raised his nose.

"Come on, Lao Ke. When you get back to the ground, you think the surface gravity is too high, and you will panic." Zhang Mai wiped the facial cleanser on his face, and hit him mercilessly like a white-faced Cao Cao Looking at my roommate.

Lao Ke, who was attacked by the crowd, stared at him and posed in a fit pose: "Maizi! Be jealous, I am a muscle!"

"Well, chicken..." Zhang Mai looked up and down with the same eyes as he looked at the roast chicken, and he got goosebumps all over his body when he saw Lao Ke.

After a few people washed up indiscriminately, they came out of the dormitory, and the luminous ceiling in the corridor emitted a soft light.These rays of light completely simulate the sun's rays, supplementing ultraviolet rays for these people who have lived in the satellite for a long time.After leaving the dormitory building, several materials looked up at the virtual sky that provided lighting.This layer of canopy, which is more than 6000 meters away from the ground of the residential area, is at the bottom of the functional control area of ​​the second-generation wind-type integrated space satellite city. It not only provides lighting for the residential area in the entire satellite, but also is responsible for precipitation, air replacement, dust filtration, etc. A series of functions.

Of course, there is another very important function.The outer layer of the satellite is a solar panel, and the inside is where the sun rises and sets.It seems to be troublesome to use the sky simulation.Therefore, the engineers and technicians responsible for the construction of the sky city added a function to the virtual sky that made people have to complain.On the ground, Zhang Mai, Lao Ke and other materials are enjoying the great convenience brought by this function.

"Damn it! Isn't it already twenty past eight!" Lao Ke raised his hand, pointing to the huge printed theme bag in the sky that displayed the time in Arabic numerals.Two black dots representing seconds with a diameter of tens of meters flickered silently, just like Zhang Mai and others who were watching it in a daze under the mockery.

"Damn! Our scheduled ship back to Earth today leaves at nine o'clock!" A guy with broom eyebrows said while looking at the theme bag in a daze.The people next to him nodded silently.

"Damn! Why don't you hurry! Find a car and find a car!"

……

Today is the day when the third-year students of North China University of Technology complete the gravity-free study of the space branch and return to the ground.At the same time, this is also the day of winter vacation. Most of the students who have been on the satellite for several months will return to the ground to spend their third Spring Festival in college.At the beginning of the third school year, the excitement of new satellites had already overwhelmed the unchanging life in the sky.This group of guys said that they are returning home like an arrow, and they are not adulterated at all. Of course, they have their own plans for their winter vacation life.

There is one more thing that is very important to them.That is they need to decide where to intern next semester.This is also the teaching method of "combination of work and study" implemented by the school.After two and a half years of study, the students need to use practical work to test how well they have mastered the basic skills. It is also necessary for these future space practitioners to understand the gap between theory and practical application, so as to learn better an important link.Basically, the half-semester internship stage almost determines their future jobs.

A few people hurriedly stopped an unmanned car, jumped on it and sped away to the central elevator.After the elevator presses the fingerprint, go through the control layer from the central elevator to the low-gravity area where the teaching area of ​​the school is located.On the satellite, unlike on the earth, the balance moment is very important. If there is a large-mass object transported on the central elevator, a counterweight is generally required.However, the quality of these few people is not even a hair on the entire satellite.So, they don't need to wait for the counterweight at all.

Gradually entering the low-gravity zone, the feet that were originally standing firmly on the elevator floor began to feel a little floating.After reaching the number of floors, several people raised their feet high, landed lightly, and walked forward sprinting.This is not a microgravity area or a gravity-free port area, and there is no teleporter for them.When they arrived at a closed gate, they took out their student cards and swiped them on the unattended gate, and a small gate next to them opened.Land is expensive on satellites, and the school does not have a luxurious gate.Different from the living area, because of the low gravity in the comprehensive area, most of the buildings are divided into large squares similar to cabins, and there are no open buildings like the living area.

"You guys, you're late again!" Crawling out of the passageway, a few of them sneaked into their automation engineering department. They just turned around from the elevator when they were blocked by a tall girl with long hair. Stopped, she glanced over, and felt that she was a bit shorter after a few pieces of material.

　New book, new book!
