After Nina signed the exile letter, she handed Meng Xingchen a small chip: "The home planet has been transformed by nearly thirty percent, and it is no longer the same as when we left, so this may help you live a better life over there." ”

Meng Xingchen did not refuse her, and after taking the chip, he put it into his private AI, 10,000 biabi. This is a mid-level officer's salary for at least half a year.

Although there is still room for heavy metals to circulate, the hard currency is still Bija, which can be directly converted into various energy sources and is currently the most liquid hard currency.

"I know you've been put under house arrest after you go back from secret training, although you shouldn't worry about eating and drinking, but because you refuse to upgrade the AI, so there should be no source of income, these are also the most I can take out for the time being, the military is currently trying to carry out the Jupiter project, the end of the world has brought too much change to the solar system, Jupiter and its small star belt have been solidified, and the strange creatures on it have become the biggest test of our landing, I have been back and forth to Jupiter three times in the past three years, and each time I will lose half of the manpower and millions of mechanical troops. At present, it can only establish a temporary foothold on the semi-metallic Jupiter, and this year the scientific and technological personnel of your Meng consortium have landed one after another, and it is estimated that the next key task is to pioneer Jupiter, so the share of support for the home planet is becoming less and less, and after you go back, it is estimated that we will not be able to meet again in a short time. Nina made a decision, although she rejected the voice, but she did not exclude Meng Xingchen from accepting it, after all, there are many people who have doubts about the history before the end and the real situation about the end of the world, but due to the blowout development of science and technology, most people have no time to engage in historical research, after all, what happened cannot be changed, many people think that the real reason is not so important, what matters is how to rebuild human civilization and continuity.

Meng Xingchen nodded, then looked at her private AI floating beside Nina and said, "Don't rely too much on artificial intelligence. ”

When Meng Xingchen left under the leadership of the two soldiers, Nina's personal AI said in a soft female voice, "He doesn't seem to like me very much." ”

"He doesn't seem to have anything to like, don't mind. He just prefers to rely on himself, and his AI basically acts as a communication device. After all, the consortium members who haven't upgraded their private AI at the age of twenty are estimated to be the only ones. Not to mention the nobles in the consortium, even ordinary residents or rebels on the home planet will not reach the age of twenty and have not upgraded their professional AI. Because the existence of your AI is inseparable from us humans, isn't it? Nina looked at the disappearing figure outside the door and said lightly.

"Understood! He's important to you, he's special. Nana can feel your feelings for him! Nina's AI said.

"Nana, your relationship system is becoming more and more in sync with me, but your professional specialty is not emotional, and it's good to feel this." Nina said to her AI.

Although the private AI and the owner can communicate with brainwaves, most people still prefer to use words to communicate with the AI when they are alone, which makes it more human.

The position of the lunar inhabitants and the parent planet Earth has changed after the apocalypse, first of all, the Moon is now closer to the Earth, while the Earth is deviated from the relative position of the Sun, but due to the severe evaporation of the surface waters and the physical trauma caused by the large collision, the mass of the whole Earth is relatively smaller.

Another change brought about by the end of the world is the change between the major planets of the solar system, because the meteorite group not only hit the planet of the earth, but also several other major planets have been impacted, and the closest Mercury to the sun is a direct impact planet, so it has disappeared in the solar system, and its fragments have caused continuous collisions with other planets in the solar system, resulting in the so-called apocalypse lasting for a long time.

And the degree of metallization of several major planets has reached the requirements of landing, and now Mars and Jupiter have become the most suitable planets for human development, and Jupiter is a giant planet, so once developed, it will have a longer use value than the earth, so most of the current scientific research of mankind is carried out around Jupiter and its outer planetary belts.

Transportation equipment to and from the moon and the earth is not available every day, but the consortium has its own transport team, especially the Alpha consortium, which is mainly based on military strength, and has three normal transport planes: large, medium and small, Nina directly used a small transport plane on hand in order for Meng Xingchen to reach the home planet safely, and the captain was a relative of her subordinates, so she directly arranged Meng Xingchen in the warehouse, and now Meng Xingchen has been removed from the Meng consortium, and the information on his private AI is just an ordinary exile, Therefore, it is normal to follow this small dual-use aircraft to Earth.

There is no trouble in the handover procedures, it seems that Nina has already taken care of everything, which makes Meng Xingchen feel more apologetic in his heart, originally he could have a good relationship with the goddess in the hearts of many people, and even if he wanted, he could become a high-level member of one of the three major consortia, but all this became an impossible hypothesis because of his obsession.

According to the rules of exiles, on the day you arrive at the penal prison, you need to learn the prison rules and receive the exile mission.

Today, there are no so-called countries on the earth, there are only habitable groups and danger zones unsuitable for human habitation, and there is a transition zone between the two.

The inhabitable part of the ground is also discontinuous in patches, and the underground is a large area of old shelter, because of the huge underground part, even if humans leave the shelter that has no sunlight all day long, they are not really deserted, the underground shelter becomes a large processing plant and warehouse, and the surface is some commercial and entertainment areas and the largest military area.

Ring City, is the parent planet surface jurisdiction belonging to the Alpha Consortium, although it is not the largest surface town, but it has its unique geographical characteristics, in the post-apocalyptic surface, water has become the most scarce resource, although the development of science and technology has made drinking water no longer so scarce, but the real natural water source has become a key protection object, and the ring city is adjacent to a natural water source of the surface of the city.

It is said that it is the surface, but in fact, it is not true, because the end has caused geological variation, the real surface has become a dry earth dominated by cracks, desertification and metallization have become the mainstream landforms, and the forests in some impact areas have also become strange forms because of geological changes, scientists call it metallization, that is, the metal content of plants has increased, and it is difficult to be listed as purebred plants anymore.

Therefore, the living area of the people around the city is at an altitude of more than 100 meters above the ground, and the ground is connected by some stout elevators and short-distance conveyors.

Meng Xingchen was placed in the C3 area of the sixth ring road in the outermost part of the ring city, which is one of the closest areas to the ground, and it is also the residence of most exiles, according to the provisions of the joint constitution, as long as the exiles do not have major violations within two years, and the monthly production share meets the standard, they can move to the inner ring area, some short-term exiles even choose to settle down in the urban area directly after the expiration of their sentences, and some even mix with the low-level management of the urban area through some connections, but this is the limit position of the exiles, After all, residents who have violated the joint constitution are not allowed to be elected to the middle and upper echelons.

Looking at the cracked earth on the surface and the patches of mechanical urban areas, Meng Xingchen seemed to feel that yesterday and today were like living in two different worlds, the air of the home planet was turbid and full of the smell of mechanical oil, and even in his cell, which was only ten square meters, there was a small universal production machine.

The reason why this kind of production machine is called universal is that it can directly convert some metals or ores and some objects with micro energy into pure energy form - Biya Energy, and then convert it into currency forms of different denominations according to the requirements of users - Biya coin.

It's just a terminal, and its central control is directly in the central hall around the city, which in turn is directly connected to the Alpha Consortium headquarters via the crypto space station.

This convenient "storage all-in-one machine" is the creation of the Meng consortium, which has only been put into use in the past five years, and its convenience and speed make many people love it, but the one in front of Meng Xingchen is the lowest configuration, and even the noise of operation can make people with poor sleep quality insomnia.

The aristocracy is a small and lightweight model, plus a noise-clearing function, even if it is silent.

Nina's arrangement is only in the procedures for entering the ring city, once she is assigned to the cell, there is almost zero place for her to interfere, after all, the military department and the exile department are different subordinates, even if they are the same Alpha Foundation, the family branches and factions they belong to will be different.

"Ten hours later, there will be a formation, and you'll have ten hours to learn the rules of the city and the related renovations of the exiles." The Warden is a robot, and every exile here will correspond to a robot Warden, so don't think about escaping or anything.

Moreover, according to the geographical environment of the ring city, even if you are lucky enough to leave the ring city, the external environment on the surface is difficult to be suitable for human beings to survive for a long time. So escaping from prison is no different from committing suicide, unless you have a good means of transportation and a good fortune. Otherwise, don't even want to leave here!

For humans with private AI, learning is not a difficult task, AI can burn a lot of knowledge through information processors, and humans can directly retrieve the required information as long as they synchronize the frequency of brain waves, such as city rules and maps, the memory of a small half of a book, using AI only takes half an hour is enough, and most of the ten hours given are actually for new exiles to adapt to the new environment and used to "reverse jet lag".

As Meng Xingchen's private AI is a painful thing, but fortunately, his AI has not been upgraded, and he is the first batch of newborns after the apocalypse, and the AI used is the most primitive version, although the function is no different from the subsequent version, but it is the most sluggish in terms of "feelings".

Today, his AI is still using the metal mix it used when it first appeared, and the speed and intonation of speech are the most "pure".

"The city rules and maps have been burned!" Metallic prompted emotionlessly.

"Well, open the encrypted notepad, and the status is AI blocking mode." Meng Xingchen commanded in a low voice.

The so-called AI shielding mode is a "paper" board provided by AI with a holographic image, and the recorder writes it by himself, while the AI does not have the permission to browse, and even after it is stored, it is just a piece of chaotic code, and only the writer or the writer can authorize it to present the authenticity of its content.

Due to the mutation of the forest, paper products are now almost extinct, holograms have replaced all paper products, metals and the emerging chemical industry have replaced the old era of chemical products before the end of the world, Meng Xingchen still had the luxury of a notepad of paper products when he lived on the moon, but at the moment when he was removed from the Meng consortium, all his property no longer belonged to him, even if it was a commemorative notepad.

"In the twentieth year after the apocalypse, I once again stepped into the home planet - Earth! This is the first note here, and as the situation allows, I will record some of my important events here in order to get closer to that truth. ”

According to the information provided by the map around the city, there are hundreds of deep ditches within 100 kilometers around the city, the deepest has reached a depth of 10,000 meters below the surface, and the temperature of the core of the earth is gradually getting lower, which is not a good sign. There are no clues about the truth at the moment, maybe it will take a few night's sleep? I hope so......"
