"In the new era 2526, the earth's resources are scarce, the development of human beings for science and technology has reached a critical point, for the continuation of life, human beings began to try to explore the universe, and the implementation of human migration plans, in the long years of exploration, the technology of interlude space was invented, this is a new technology that can cross space, if space is a straight line, then, interlude space can bend the straight line into a "U" shape, in order to shorten the distance in space, all scientists on the earth are cheering, this is a cross-era research results, But the truth is that they have opened the gates of hell, and the interlude space is not a shortcut to the universe, but a gate to hell, and the space that is opened is what we call the blood realm......"

Crash!

The elderly Professor Luo was pointing to a magnified chronicle to tell, but at this moment, the teacher's wooden door was opened, and a fifteen or sixteen-year-old boy yawned into the classroom and walked to the back row as if sleepwalking.

Professor Luo frowned and said, "Yan Feilin, you answer, what is the Blood Realm!" ”

"Huh?" The yawning boy turned around, rubbed his hair, and said, "Professor, are you asking me?" ”

Professor Luo said, "So, could you please tell me that there is anyone else in this class whose name is Yan Feilin?" ”

Yan Feilin smiled and said, "I'm just curious, is it necessary to ask me such a simple question?" ”

Professor Luo's eyebrows furrowed, and he couldn't help but clench his fists.

Yan Feilin, male, 16 years old, a second-year student of Hwaseong First College, has a D level in the martial arts assessment, a A in the ideological assessment, an S in the mechanical assessment, a A in the academic assessment, and a A in the strategic assessment!

There are five categories of subjects in the Academy of the Earth Federation, and there are many small subjects under them, and the comprehensive results are used to determine the level of the big subjects, and among the five subjects, one S level and three A levels, although the results of the martial arts assessment are worse, but they can be called geniuses in any school.

However, if it weren't for Yan Feilin's grades being outstanding, with his conduct rating, he would have been expelled from school a long time ago, and then kicked out of school, and many teachers and professors in the school couldn't help but sigh when they heard Yan Feilin's name, this is indeed a genius, many people have high hopes for it, but unfortunately, in the end, it is a genius who was played badly by himself.

On the other side, Yan Feilin saw that Professor Luo was silent for a long time, so he could only spread his hands and said: "The so-called blood world is another space, and the interlude space plan has successfully opened the door of space, but the other end of the door is not other planets in the universe, but a different world space unknown to human beings, which is full of monsters, through the space gate, most of these monsters are brutal and ferocious, they invade the earth, and at the same time open a chapter of war, a war between humans and monsters that has not ended for one hundred and twenty-seven years. ”

Professor Luo said, "Please continue to elaborate on the Scarlet Moon Covenant. ”

Yan Feilin said: "Powerful monsters have extremely high genetic evolution and strong bodies, human high-tech weapons are extremely vulnerable in front of them, in the first ten years of the appearance of the blood world, human beings have been unilaterally slaughtered, so human beings have signed a peace covenant with some mild monsters, willing to live peacefully with each other, and it is precisely because of the help of this part of the monsters that human beings can recover their disadvantages little by little and not perish, and this alliance is called the Scarlet Moon Covenant." ”

Professor Luo said: "So how did the human revolution that took place during this period almost lead to the breakdown of the Scarlet Moon Covenant and ......?"

"Isn't it just that some humans are dissatisfied with the alliance with the monsters, and have formed a revolutionary army to oppose the alliance!" Before Professor Luo finished speaking, Yan Feilin said impatiently: "Professor, I can memorize the chronicle in your hand backwards, in the last midterm exam, my chronicle course was A+, or is it because you deducted my conduct evaluation, otherwise I should get S, do you think it makes sense to ask me these questions?" If you want to punish me for being late, you might as well let me clean the windows. ”

"Yan Feilin!" Professor Luo glared at him angrily, slapped the table and said, "Okay, then you go and wipe all the windows on the second floor for me, and you won't be allowed to go home until you finish wiping them." ”

Yan Feilin spread his hands, and then yawned and left the classroom.

Professor Luo looked at Yan Feilin's back and said hatefully: "The erector can't be taught!" ”

……

Leaving the classroom, Yan Feilin looked at the row of glass windows, took out a palm-sized discus from his backpack, and after fiddling with it, eight legs grew on the edge of the discus, climbed up the window like a spider, and after spraying out the cleaning liquid, he began to wipe the windows, while Yan Feilin took out a bunch of mechanical parts and sat in the corner to fiddle with them.

Study? This is too luxurious for Yan Feilin, because he has no time, he needs to work to earn money.

Since he was sensible, Yan Feilin was an orphan, even if he got a scholarship with excellent grades, for him, the money was far from enough, so he needed to make money to support himself, and since he needed to make money, he naturally didn't have much time to stay in school, and as for his academic results, Yan Feilin didn't care too much.

15 years of being alone has made Yan Feilin understand that survival is always the most important, with his grades in school, after graduation, he can join the hunter organization and become an excellent monster hunter, or enter the federal army, go to the front line to accumulate some merits, and become an officer.

But these are not what Yan Feilin wants, because these jobs are too dangerous, he just wants to live a small life in peace, such as becoming a mechanic, being employed by some weapons production companies, or mixing into the logistics department of the federal army, being a mechanic, of course, the most important thing is that these jobs are safe.

"The most important thing is to be alive." Yan Feilin muttered while fiddling with the parts, "Plain is true." ”

While muttering and stretching, Yan Feilin followed the window and looked at the sky outside the window.

In this era, because of serious air pollution, the sky is always gray, and in the middle of that gray sky, there is a huge blood-colored vortex, which is the so-called blood world, from which the monsters that are rampant on the earth fall, and many scientists have tried to close the interlude space and make the blood world disappear, but unfortunately, they all failed, and the monsters in the blood world continue to invade, which also makes the earth, which is gradually coming to an end, even more dilapidated.

But at this time, a blood-red meteor suddenly fell from the sky, Yan Feilin couldn't help but be stunned, and then got up and walked to the window to look at the sky.

In the Blood Realm, many blood-red lights shone brightly, like stars all over the place, and then these blood-colored stars turned into meteors, falling from the Blood Realm, turning into a bright red meteor shower.

Yan Feilin said: "Is there another monster coming, I don't know where it will fall." ”

The monsters in the Blood Realm often come and go, and then land in various places, and those sporadic monsters appear are fine, but occasionally there is a large-scale invasion of monsters, and that is a disaster, and you need to be ready for battle at any time.

Yan Feilin muttered, but then his eyes widened and widened, because the meteor shower became denser and larger, and it became bigger and bigger, and the posture actually fell in his direction?

Woo-la, woo-la!

A shrill siren sounded, and a mechanical voice sounded from the loudspeakers around it: "Warning, warning, city-wide secondary yellow alert, please quickly enter the designated shelter, repeat, warning, warning......"

Yan Feilin was surprised, the third-level alarm generally belongs to the fire and the like, while the second-level alarm belongs to the invasion of monsters, and it is also a city-wide alarm, which means that there are a large number of monsters invading, it seems that the monsters that fell in the blood realm are really coming to Huacheng.

"It's bad luck." Yan Feilin couldn't help but take a sip and said: "Doesn't the master just want to live a small life in peace, how could he encounter this unlucky thing, no, the gentleman does not stand under the dangerous wall, the master has to hurry up and apply oil to the soles of his feet." ”

Yan Feilin quickly stuffed the pile of parts into his backpack, grabbed the clear robot that was still wiping the glass window, and ran out.

Meanwhile......

In the whole college, there was chaos at the moment, and the old-fashioned Professor Luo didn't care about continuing to class, so he hurriedly ran out of the classroom, and saw that the security of the security department continued to pour into the teaching building, directing the students to evacuate.

Professor Luo grabbed a security captain and said, "How is it?" What's going on now? ”

The security captain said: "The alert from the Monitoring Bureau, most of the newly fallen monsters in the Blood Realm will appear in the A3 area, and the school may be the first to bear the brunt, and the students must be evacuated as soon as possible." ”

"How so?" Professor Luo said blankly: "Isn't there a protective layer?" Why can't the protective layer create a barrier to keep those monsters out of the city? ”

The security captain smiled bitterly: "How can I know about such a thing?" Maybe it's because the monster that fell this time can ignore the protective layer, or maybe it's a monster with corrosive ability that melts the protective layer, Professor Luo, you still don't care about so much, these annoying things naturally have a headache for the monitoring bureau and the city defense army, and it's the right thing for you to follow everyone to take refuge now. ”

"Evacuate, evacuate, yes, I'm going to evacuate, no, I can't go, what about those things." Professor Luo was a little at a loss, and after pacing in place twice, he suddenly tugged on the shoulder of the security captain and said, "Call two people for me immediately, and come with me." ”

The security captain reluctantly persuaded: "Professor Luo, it's this time now, everything is outside the body, only a small life is the most important, it's better to take refuge with me first." ”

"Nope." Professor Luo said: "Those things are too important, if you don't go, I can go myself." ”

The security captain helplessly lowered his hand, still beckoned to call the two of them, and followed Professor Luo in the opposite direction.
