Hypoxia era

In the interstellar era after the catastrophe, there are thousands of ruined stars in the star field covered by human civilization, less than a hundred semi-ruined stars, and only one fully prosperous planet. The original population of trillions has dropped to tens of billions.

Civilization is regressing, new technology is developing abnormally, and the road to interstellar prosperity is long and difficult.

The X-338 semi-ruin star is three times away from the Y-1077 ruin star, and it lasts three hours. Students at this time can't just sit and log in to the teaching system, and listen to a professional teacher to do a cataclysmic science popularization.

Cataclysm is the basic knowledge that every interstellar citizen will be exposed to since entering school. However, the previous introduction is a little simpler. It can only be said that the catastrophe broke out in 3222. Because of the lesions of oxygen atoms, all civilizations collapsed in just half a year. , the tens of billions of citizens who were able to evolve and adapt to the anaerobic environment and survived were forced to become wanderers in the star sea. After hundreds of years of painful struggle, after the population was reduced to more than one billion 310 years later, the great ancestors finally completed The order was rebuilt and the era of oxygen charging was truly entered.

This year is a special year, it is 310 years after the reconstruction of the new order.

The teacher's voice continued to flow from the earphones into Xiao Sifang's brain.

"... So far, catastrophe is still the biggest test for our human survival. Although our ancestors have been working hard for it, unfortunately, the origin of the catastrophe has not yet been found out. As we all know, a catastrophe planet may have a second catastrophe, a third catastrophe, or even more repeatedly……"

"In recent years, the Clearance Bureau has made great progress in cleaning up catastrophes. This is the progress of science and technology, and it is also the beginning of some people taking it lightly. The widely circulated theory that catastrophes are controllable is simply nonsense. Every catastrophe may restart Awaken the chain catastrophe reaction or strengthen our natural enemies, every catastrophe may become the last blow to break through the catastrophe defense line we set up."

"Everyone who chooses the combat system means that in the near future, you will be on the front line of resisting aliens, and you will also be on the front line of cleaning up the catastrophe. As your teacher, I must remind you that even if everyone thinks that dealing with Catastrophe is so easy, we can't relax a bit! Otherwise, the price we pay for it is our lives..."

When the spaceship arrived at its destination, the lecturer hung up the line with unsatisfied interest.

Before opening the hatch, the female teacher leading the third class swept every student who was nervous and apprehensive with a very solemn gaze.

"The disaster scene after cleaning is relatively safe but not absolutely safe. Please remember this. You must never act without authorization and leave the sight of the teachers."

"Keep fighting at all times when you get off the spaceship, do you hear me?!"

Fifty students answered in unison, with a sonorous tone: "Got it!"

"Okay." The woman was very satisfied with their confidence, and she rarely showed a smile, "I will be your practical teacher for the next three years. My name is Greta. I hope we can cooperate happily this school year."

After speaking, she opened the hatch and jumped down first.

"Everyone come down—"

so cool.

Seeing her sassy figure and crisp attitude, Xiao Sifang, who was at the bottom of the list, felt his heart throbbing. She also wanted to have such confidence and capital!

At first glance, the ruins of the catastrophe are no different from the ruins of the outer city. The products of the high-tech civilization before the catastrophe are broken everywhere, and there are also a few buildings that are well preserved, and the precious pre-disaster civilization is sealed and stored inside.However, even though civilizations they don't know are in front of them, the danger of acquiring these civilizations is no lower than that of the front line of battle. The more well-sealed buildings and objects are, the more unstable their internal materials are, and anything inside them may cause biological damage. The possibility of instant alienation may even cause subsequent catastrophes.

Therefore, without professional protective measures, it is not possible to step into it at will.

The people from the Yiyi Army and the Clearance Bureau are still there. After cleaning up the dangerous foreign objects that caused the catastrophe, they still need to stay here for three days to do further high-risk elimination.

The garrison site has been completely wiped out, and the surrounding materials are very safe, so the students who lined up to observe on the spot, that is, to make a preliminary experience here, and then take the team as a unit, and after being well protected, they are taken into the disaster area by the teacher to experience it for themselves .

Not long after Greta led them to the corresponding position, a man in a combat uniform came over and called her name.

Greta glanced at him in surprise, "Director Terry, why did you come here in person?"

Terry smiled, "I also have my task, how do you feel about this class of students?"

Although she didn't quite understand the purpose of coming here to greet them, Greta was quite flexible and said politely: "Every one of them is great."

"Oh?" Terry raised his eyebrows, "Is it every one?"

His voice was so soft that only Greta and a few students in the front row could hear him.

But when the students in the front row turned their heads to look at him, Xiao Sifang understood that the examiner, who had just had a dispute with him yesterday, said something about himself that was not very nice.

Greta knew what he was talking about, but she extremely hated this kind of behavior of putting discrimination on a brave man who had already managed to not be pulled apart under the circumstances of the vastly different conditions.

Rubbish should naturally be looked down upon, but contempt should never be used on a powerful person.

"Oh, really?" Greta pretended not to understand what he meant, "at least they are all excellent now, aren't they? I lead Class Three, so you can ask the teacher in Class Ten , might be more appropriate."

The innocent in the distance was sneezed by the class ten teacher of the cue, and quickly took a breath of oxygen for himself to supplement his immunity.

Terry snorted coldly: "The entrance examination doesn't mean everything, Greta."

After speaking, he turned and left.

Greta looked at his back and snorted too.

fool.

She turned her head and yelled at the students who started whispering because of his words, "Of course the entrance examination doesn't mean everything, but listen, if anyone loses the ranking to me, it's like what Mrs. Terry said Same thing, let’s represent garbage! All Class Three, do you have the confidence not to be that representative? Answer me!”

"Have!"

Greta's eyes fell to the back row.

The first one to raise her hand high was Xiao Sifang who was being targeted. Her voice was loud and her eyes were full of determination, "I have confidence!"

This is a front bar!

The students who didn't know what happened in lounge No. [-] were stunned and their fighting spirit was aroused at the same time. They are second-class residents, how could they fall behind a refugee!

"Fuck! I don't have confidence, who has confidence!"

"It's really ruthless people don't say ruthless words, so I'll just say one thing, just wait and see, teacher!"

"Speak with results!"

"Class Three is the best—"

Greta smiled again and tapped her palms lightly, "Great, every one of you is great."

No one can break a man's mind except himself.

Xiao Sifang smiled amid the high morale of the crowd, and she never gave up.

The round of the previous academy was over soon, and a certain officer in the Yiyi Army glanced at the list and shouted: "Chris Academy is ready, you can go in."

Each teacher can bring up to five students in the class at a time, and Greta needs to go back and forth ten times to bring all the students in.

After the first batch of students got ready, she sternly instructed the students who were not on the wheel: "Stand here and don't move. If anyone is not at the same place when I come back, I will be expelled immediately when I go back."

The deterred crowd immediately promised to stay close. Greta looked at Terry and the other three supervisory teachers who stayed behind him, and led the team away with confidence.

Shortly after she left, Terry ended a call and walked to the classes with another teacher.

"The performance of each class is very good. It seems that two supervisors are enough. Teacher Chen Huan and I are standing together, and we decided to lead the team to save time." His tone and demeanor are very upright, " Now there will be one from each class, and they will go with me and Teacher Chen respectively."

In class ten, Terry didn't come in order, but directly called Xiao Sifang's name, "Go with Mr. Chen, he has the strongest practical ability among all the teachers, in case of danger, he will keep your It's more likely."

"Also, put away your fancy intestines after entering the arena, otherwise no one will be able to protect you if something goes wrong!"

As soon as he came up, a big hat was buttoned down, Xiao Sifang frowned.

I'm afraid there are ulterior motives.

She didn't answer immediately, Terry's face darkened, "What are you still doing in a daze? Follow up!"

It was inevitable that disaster could not be avoided, Xiao Sifang took a deep breath, walked past him, and followed the honest-looking teacher Chen.

Just be careful.

Lu Yi, who was in the crowd, lowered his head and flicked his fingers on the identity ring a few times.

After actually entering the ruin star, all the defense cells in Xiao Sifang's body came alive. She knew how dangerous a ruin star that was not completely rejected was.

Even the undeveloped part of a half-ruin star is extremely dangerous, not to mention that the entire planet has just undergone catastrophe, and it has only initially completed high-risk rejection.

Although she is a frequent visitor of interstellar drifting, she is also extremely cautious when traveling between planets. She only goes to ruined stars in the development state, and only sets foot in areas that have been completely rejected, and she will not step a toe in other risky areas.

Therefore, this is also the first time in her life that she has had close contact with a dangerous object, and she is both cautious and cherished.

"Even if there is an isolation ring, don't touch what you shouldn't touch." Teacher Chen, who followed behind and locked the five students firmly in the field of vision, reminded, "In addition to dangerous foreign objects, there are many lurking aliens here. Ordinary dangerous Foreign objects can be separated by the isolation ring, but the aliens who don't know where they are ambushing can penetrate the isolation ring in an instant, putting you in double danger, so you must not move around."

"The main reason for letting you come here this time is to experience the feeling, which cannot be experienced no matter how many holographic videos you watch."

"Remember it, remember how small we are in the face of catastrophe."

His voice was very deep, and he clearly explained to them which places were more likely to lurk aliens, and which places were full of dangerous foreign objects.

Just as Xiao Sifang was engrossed in listening, the voice that spoke at an appropriate speed suddenly became urgent.

"Danger--"

Having been in danger for many years, she immediately jumped out of the spot, but when she looked back, she only saw Chen Huan's ferocious face and the fallen classmates.

"You shouldn't be in the combat department."

The difference in strength was too great, Xiao Sifang only stepped back one meter, and Chen Huan's fist was already in front of him.

The world went dark in an instant.
