If there is anyone who is most wary of alien visits at this time, this person is undoubtedly Zhou Chen. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

When everyone was still immersed in their own lives, or looking forward to the future, or working hard for life, Zhou Chen was saying goodbye to Li Kaiyan and walking towards the dormitory alone with a heavy heart that ordinary people could not imagine.

――――――――――――

The University of Chinese Academy of Sciences, i.e., the Graduate School of the Chinese Academy of Sciences.

Founded in 1978, it is a "big school" consisting of 16 faculties on 4 campuses in Beijing, 5 educational bases outside Beijing, and 117 research institutes throughout the country. In 2012, it was officially renamed the University of Chinese Academy of Sciences, with 10,000 graduate supervisors, including more than 270 academicians of the Chinese Academy of Sciences and the Chinese Academy of Sciences, 6,000 doctoral supervisors, 2,000 people in the Thousand and Hundred Talents Program, and more than 45,700 graduate students, of which about 50% are master's students and doctoral students.

The school implements the leadership system of "unified enrollment, unified education management, unified degree awarding" and "integration of institutes", that is, graduate students will complete course teaching in the centralized teaching campus in the first year, and then go to various research institutes under the Chinese Academy of Sciences for scientific research and practice-based teaching in the next few years.

After Zhou Chen completed the course teaching task in the "School of Physical Sciences" in the first year, he was assigned to rely on the training unit of the National Astronomical Observatories.

The dormitory is a small one-bedroom room, with an area of more than 20 square meters, with its own bathroom and kitchen utensils, and the conditions are decent, which is enough for him to live alone in the first place.

After entering the door, Zhou Chen closed the curtains on the side of the balcony, and then turned on the lights again, and the whole room suddenly became a relatively claustrophobic secret room.

Immediately afterwards, a magical phenomenon happened, and I saw that the formal dress specially prepared for the defense on Zhou Chen's body suddenly had some subtle changes.

A trace of ripples appeared on the black suit, as if the polarizers in different directions on two sides were staggered and rotated at a certain angle, and soon the strange distorted texture shrank again, like a ball of liquid metal full of tension, detached from the black suit and slowly converged towards Zhou Chen's palm.

It didn't take long for a lump of chickens to take shape, and if anyone else was there, they would have been stunned by the scene in front of them.

I saw that the metal ball exuded a luster like mercury, and suddenly the middle part collapsed downward, and then it jumped up, and the whole metal ball fell on the table not far away.

"Dandan, there is no one around now, return to your original form, and tell me about the Ferro civilization."

As soon as Zhou Chen's words fell, the strange liquid metal on the table that looked like an egg suddenly became extremely textured, the metal features on its surface became hard, and the overall shape changed again.

After some complicated internal unfolding, what appeared in Zhou Chen's eyes in the blink of an eye was a strange robot with four legs, two arms, and a cute face embedded in an arc.

"Okay......

Dandan's extremely metallic voice suddenly appeared in Zhou Chen's brain, which was not achieved through sound transmission, but was directly mapped to the brain in a special signal pattern.

This robot named "Dandan" is the central brain of the Odo civilization that Zhou Chen inadvertently obtained a few days ago.

Originating from a star system 1,200 light-years away from the solar system, the Odo civilization was forced to become a wandering civilization 30,000 years ago due to a catastrophe on its home planet.

Although it has been adrift away from its home planet for 30,000 years, the Odo civilization has not died out, but has continued to refine scientific and technological achievements on the way to interstellar wandering, and has reached the standard of a third-level civilization according to the division of civilizations.

Later, at a distance of 72 light-years from the solar system, the Odo civilization detected a planet suitable for life.

The Odo civilization, which was tired of wandering, was ready to find a planet to settle in, but who would have thought that on the way to that planet, they encountered another civilization that also took a fancy to that planet - the Ferro civilization.

This Ferro civilization is notorious in the cantilever of the galaxy Orion, they are like scavengers in the universe, everywhere they pass is a mess, the slightest resistance will be rewarded with blood and killing, and almost all the weak civilizations that encounter the Ferro civilization will inevitably be destroyed.

The Odo civilization to which Dan Dan belonged was so unlucky, and soon after meeting the Ferro civilization, a large-scale star war broke out, with tens of thousands of warships constantly destroyed in the flames of giant cannons, and the battle situation was completely one-sided.

In the end, as the flagship mastermind and the central brain of the Odo civilization, after all the life forms of the Odo civilization were killed, he activated the spare spaceship and fled to other planets where life might exist.

In the end, it came with only a few satellite ships to the solar system.

“…… At present, these auxiliary ships are hidden on the far side of the moon, because they are fleeing in chaos, so the functions of these auxiliary ships are not powerful, and they barely meet the requirements of third-level civilization warships, and they cannot compete with the warships of the Feido civilization. ”

Dandan1510 said.

Zhou Chen nodded while listening, since he got Dan Dan a few days ago, he has established a subtle connection with Dandan, in more fashionable words, Dan Dan recognizes him as the master.

There is a low-level program in all the brains of the Odo civilization, which is equivalent to the supreme law of the brain, that is, all brains can never have complete independent permissions, otherwise the self-destruction setting of the underlying program will be activated.

In other words, the brain must have a master, otherwise it will not survive.

It is precisely because all the life forms of the Odo civilization have died that Dandan, who has the idea of seeking business, will run towards the earth in a panic, because this is the planet with the greatest possibility of life nearby.

In order not to activate the destruction setting, Dandan kept sleeping until its "assistant program" found Zhou Chen, and then it hurriedly ran over to recognize its master.

Having chosen himself among billions of people, Zhou Chen thought at first that this was a huge opportunity given to him by God, but when he learned from Dan Dan that in the depths of the starry sky, the three main fleets of the Ferro civilization were also heading towards the earth, he felt in big trouble.

Even the Odo civilization, which has reached the third level of civilization, is not the opponent of the Feido civilization, let alone the earth!

"According to the universally recognized division of civilization levels, civilizations that have not invented steam engines and have not used electric energy belong to zero-level primitive civilizations, and those who have invented steam engines and begun to use electric energy are first-class steam civilizations; Those who have preliminarily mastered nuclear energy technology but cannot break away from the home galaxy are second-level civilizations; Those who have mastered the energy shield technology and have the ability to travel interstellar are the third-level civilizations. ”

Dandan's introduction to the hierarchy of civilization is still vivid, according to this standard, the earth has only just broken free from the ignorant primitive civilization for a few hundred years.

"Dandan, the Ferro civilization will not reach the earth until 45 years at the earliest, so in these 45 years, what can we do to deal with them?"

"The Ferro civilization is a mid-to-late third-level civilization, and the current state of the earth has just reached the second-level standard, and even the use of nuclear energy has only mastered the level of heavy nuclear fission, even with my participation and help, it is impossible to reach the point of competing with the Ferro civilization in 45 years."

"If there is an engagement, the probability of defeat is 100%."

A hint of affirmation appeared on Dandan's cute face.

"So what if you don't choose confrontation, but choose to evacuate?" Zhou Chen frowned and said.

"If the goal is just evacuation, through 45 years of construction, it should be able to meet the needs of about 300 million people to evacuate safely; If follow-up supplies are not taken into account, the overload could sustain the evacuation of up to 1 billion people. However, this will seriously disrupt the ecological balance inside the ship, and it is predicted that the fleet will run out of resources in 36 Earth years...... Dan Dan is not recommended to take the second option......"

"Only 300 million ......"

Zhou Chen fell silent.

The safe evacuation can only take away more than 300 million people, and the overload can take away up to 1 billion people, but it will exhaust all the resources on the fleet after 36 years.

In fact, he didn't know that it was not a small number to be able to evacuate 300 million people safely, but compared to the world's more than 7 billion people, this scale is still too small, that is, the vast majority of people cannot evacuate the earth!

It's a very brutal choice!

And even those who can evacuate the earth are estimated to be able to wander in the universe for the rest of their lives. Far away from home, upside down, how is it a good life?

Shaking his head, Zhou Chen let himself stop thinking about this problem, the top priority now is how to carry out this "planetary escape" plan, and now he has not even made preparations, and it is meaningless to think too far away.

"Dandan, when will the spacecraft that will take me to the far side of the moon be ready?"

"It's ready, but for the sake of secrecy, the time point is 10:25 tonight, when it will be able to effectively avoid the detection of radar stations and high-altitude satellites."

Zhou Chen nodded lightly after listening, he had no objection to the timing chosen by Dandan.

After all, I am in Beijing, as one of the largest countries on the earth, there is no need to say much about the defense of the first good place, maybe there are several satellites monitoring the sky over Beijing at this moment, for security reasons, it is understandable to set off in the dead of night.

Next, Zhou Chen disguised Dan Dan as a creative table clock, and he was ready to get some sleep.

Maybe it was because he was facing a defense, or maybe it was because he was under too much pressure to learn that aliens were coming to Earth, he didn't sleep well all night last night, and at this time he determined the direction of the future, and a wave of fatigue hit him, and he slept very soundly all afternoon.

In the evening, he went out for dinner, and Zhou Chen stayed in the bedroom waiting for the arrival of the spaceship.

At 10:25 p.m., the black hole could not be seen in the night, and the undulating cries of frogs in the pond not far away could be faintly heard.

Over the Huairou district in the north of Beijing.

A black-looking spaceship is approaching silently at a very high speed. When the spacecraft flew over the Yanqi Lake Campus of the University of the Chinese Academy of Sciences, the spacecraft suddenly came to a standstill as if it had violated the law of inertia, and then slowly descended.

Zhou Chen, who had been waiting at the pick-up site for a long time, saw the spaceship of the Odo civilization for the first time, and couldn't help but exclaim in his heart.

It is a small spaceship eight meters long, four meters wide and three meters high, the overall lines are smooth and graceful, and from a distance it looks natural and ingenious, and the color is black all over, like a bird ready to go.

When the spacecraft stopped, he hurriedly stepped into the spacecraft, and then the spacecraft accelerated towards the moon 380,000 kilometers away.
