Ten thousand I am across the heavens

Chapter 1801: Generational Disruption and Inheritance

Elsa and Nangong Wudi actually wanted to help. But after trying a few times, they found that they couldn't help at all. The scientific research conducted by Lan Nuo was hundreds of years ahead of their cognition, and the technology level spanned more than one era.

Even if they have a long life span and rich experience, they can't help in a short time. On the contrary, artificial intelligence can help a lot.

They found the original human species gene library and the gene records of humans after sequencing in the database. Based on these records and comparing them with his own genes, Lan Nuo began to repair the human genes of this world.

This workload is enormous. Without the cooperation of artificial intelligence, it is basically impossible to complete it in our lifetime.

Human genes are like a book that is so long that a person cannot finish reading it in a lifetime. Lan Nuo can only provide ideas for repair and modification. It is impossible to read it from beginning to end and modify every fragment. The redundant parts cannot be removed at will, but should be restored as much as possible. After all, no one dares to be sure whether these genes have played a vital role in billions of years of evolution and natural selection? Or whether they will play an important role in natural selection in the future.

While they were working, the robots began to go into hibernation one by one, leaving only a few robots to maintain the operation of society and keep the Planet Ark sailing towards its distant goal.

After all, the lifespan of these robots is limited, and the number of replacement parts is also limited. In the harsh natural environment, it takes too many resources to restore them to a lifelike state after they are damaged. Therefore, after hope is born, most robots are put into cold storage. They will not be put back into operation until the new generation is truly born.

Lan Nuo did not let them wait too long, after all, he had developed these technologies before. Biotechnology was one of the few technologies that could still be used to a certain extent after crossing the world, especially in a world where human genes had not undergone major changes.

With the help of past experience and a large number of artificial intelligences in this world, the first batch of sperm and egg cells successfully completed their repair and ensured that half of them would be born as females. The only problem might be that a considerable part of the genetic blueprints used by the born females still came from Lan Nuo. In a broad sense, these girls can be regarded as Lan Nuo's feminized clones in the future.

In order to ensure the genetic diversity of the human race and prevent tragedies caused by inbreeding, Lan Nuo chose to restore the destroyed sperm and egg cells in the gene pool as much as possible, rather than cloning his own genes. This also made the birth speed of newborns not as fast as expected.

Dansheng was the first child on this planet to develop to the fetal stage after the mass extinction. However, before he was actually born, his development was actively suppressed and put into a pause.

Artificial intelligence is not ready to accept this batch of newborns. The main reason is that they need newborns and they want as many of them as possible to be born in the same batch, so that they can ensure that before their mechanical bodies reach the end of their lifespan, they can cultivate enough new generations to take over their baton.

Another reason is that the eldest son indiscriminately destroyed the genes of almost all living things, which caused the entire biosphere to fall into mass extinction.

It is not just humans that need to be restored, but other species as well. Previously, artificial intelligences had only been able to synthesize some fish, which are the most evolved vertebrates they have restored. Even so, they often have a very high mortality rate due to genetic mutations, making them difficult to breed.

Lan Nuo saw all kinds of meat at the night market. In fact, most of them were organic synthetic foods, or artificial meat, but the taste was so good that even he couldn't tell. But if a large number of new humans were born, the cost of obtaining food through artificial synthesis would be too high, and the restoration of the biosphere was imminent. Even though the world is in an ice age now and the surface temperature is terribly low without the sun, the ability of organisms to transform the planet is still huge, and humans in the new era must learn how to live in harmony with nature.

Therefore, after the first batch of fetuses developed successfully and verified the feasibility of the technology, they used technical means to suspend the development of this batch of fetuses, and then started the restoration of the entire biosphere.

Compared with restoring other species in the biosphere, the difficulty is much lower. It is not that humans are much more complex than these animals. From a genetic level, humans are just one of many large primates, and the genetic level is not necessarily much more complex than them. Restoring other species is easier because there is a higher tolerance rate.

As intelligent creatures, humans can hardly tolerate the large-scale occurrence of mental retardation and deformity in their offspring. However, this series of problems in animals can be solved little by little through artificial breeding from generation to generation.

In fact, this can be seen in the breeding of animals in ancient times. Close relatives of humans do not marry each other, which does avoid diseases that may be caused by close relatives marrying. But in fact, if we put ethics aside and talk about it purely from the perspective of species evolution, backcrossing, that is, letting the offspring mate with a mother or father with a certain kinship, is very conducive to retaining excellent traits. When the ancients bred species such as horses, they used this breeding strategy extensively.

Theoretically, humans can do the same, but not in reality. If there are deformed animals, they can just be killed or thrown away. However, humans, as intelligent creatures with intelligence and civilization, cannot do such a thing. This is the biggest difficulty in restoring humans. In the restoration process, even the slightest mistake cannot be tolerated.

Relatively speaking, other species are fine as long as they can survive and reproduce. As for the various bugs in genes, there is a saying that goes, if a program can run, then don't touch it. Animals that cannot adapt to the environment or do not meet people's requirements will naturally be eliminated in natural selection and artificial selection, and after several generations of breeding, they will become the species that people need.

During the scientific research process, there is also an episode worth mentioning. For this civilization, this is indeed a small episode, but for Lan Nuo, it reveals a piece of history that makes him extremely regretful.

In the process of scientific research, he came into contact with many scientists who were once human beings. Even if he was only in contact with artificial intelligence copied from their thoughts, he could still feel their wisdom when they were still alive.

Among the scientists who collaborated with him, there was one who got along extremely well with him, to the extent that Lan Nuo even felt that the other person was a worm in his stomach.

After asking, I learned that he was the scientist who first proposed that the eldest son might have a powerful soul, and that the soul could still cause mass extinction. He was also the scientist who made the development of this planet different from the original history. After learning this news, Lan Nuo actually had some guesses. After a few months of getting along with him day and night, he finally confirmed a helpless fact. This artificial intelligence next to him, which seemed to be in perfect harmony with him, was most likely the last remnant of a certain self left in this world.

The road to the growth of civilization is full of thorns. No one dares to guarantee that they will survive to the end. Even a traverser who has experienced hundreds of battles and hardships in countless worlds cannot guarantee that he will survive to the end.

After crossing the long time of tens of thousands of years and looking at himself who had once drifted to this planet, Lan Nuo became more determined to continue the civilization on this planet. This is not only the salvation of a civilization, but also the fulfillment of his former self's last wish.

"We have such a good rapport, how about you just use my clone as the child you adopt in the future?"

The slightly dull scientist smiled warmly upon hearing this: "Okay, but I have to think about how to explain it to him. I don't have a mother."

Lan Nuo scratched his head in embarrassment. He was really a nobody. He had traveled through time and the mass extinction was imminent, but he was still single. Could he only say that he was worthy of being himself?

As species in the biosphere are restored one by one and the genes of humans are restored one by one, the culture dishes in the human gene bank have begun to operate efficiently. It is estimated that in the next twenty years, 15 million newborns will be produced one after another and born in different families in batches.

After 20 years, the first batch of newborns will have grown up. They will fall in love freely and reproduce naturally. Your offspring will replace the artificial individuals in the gene pool of the species and gradually complete the population replacement. It is expected that within a hundred years, all robots and artificial intelligence will gradually withdraw from the stage of history, completing a smooth handover of civilization.

Lan Nuo looked at his own remains and adopted his clone excitedly and nervously. He didn't know how to describe his complicated feelings. History had already happened. His eternal sacrifice could not be rewritten, but he survived in another way and even saved a civilization on the verge of extinction with his own hands.

The ignorant newborn was named Lan Meng. Fortunately, blue, as a color that is universally present in the human species' cognition, can exist as a surname in most civilizations.

Lan Nuo silently looked at his own wreckage, how he took care of this little baby, how he sent her to school, how he taught her the history and culture of this planet, how he cried when little Lan Meng was sent to kindergarten for the first time, how he was spanked on a stool for being naughty, how he grew up to adolescence and started to rebel, how he fought wits with his adoptive father to play games for a while longer, or how he was called to school by the teacher for his early love.

A scene of the child's growth awakened Lan Nuo's very distant memories, which happened before he traveled through time. Thinking back to his former childish self, he couldn't help but feel a lot of emotion. Who knows what kind of life his clone in this world will lead in the future?

Lan Meng is getting older and older, and gradually becoming more sensible. After finding a job, he spends less and less time with his family. I don’t know if it’s the influence of his original personality, or if artificial intelligence has really developed some emotions that only humans have. After the child left him, the artificial intelligence corresponding to Lan Nuo seemed a little lonely, but it still stood loyally at its last shift.

And his old body can no longer withstand the wear and tear of time. Parts cannot be replaced. Machines age more easily than the human body. Although there are no signs of time on the contents, the joints are no longer flexible, the skin is becoming more and more loose, and even some injuries on the body can never be repaired, but they are leaving traces of time on his body.

"Tell me, how long can I stay with him? I'm afraid this body won't be able to hide anything from him in a few years." In front of Lan Nuo, the mechanized self was performing routine maintenance on his body, applying artificial paint to the damaged parts of the skin bit by bit, and putting makeup on his face to draw out the traces of aging over the years.

Lan Nuo was helpless about this and could only help his former self to repair his broken body as much as possible. This body was activated much earlier than others. When he was doing scientific research with him, it had already consumed a lot of the body's lifespan. Now it is more aged than other robot parents.

The mechanized old father was worried that his child would eventually discover his identity as a robot. Lan Meng, who was on a business trip, finally got a chance to rest and went home, but brought back an unexpected gift for his old father.

……

"Don't look at me like that. You're old, and the bearings and joints have aged a long time ago. If you don't take them apart and maintain them properly, they will all rust together in a few years." Lan Meng took out special knives and cleaning equipment for maintaining the robot from the toolbox.

Over the years, in order to prevent children from noticing the clues, most robot guardians have not disassembled the skin and performed maintenance on the internal joints. The joints inside the skin have indeed suffered a considerable degree of wear and rust over a long period of time.

But he didn't expect that all this had already been discovered. But thinking about it carefully, it seemed normal. After twenty years of living together day and night, it would be very difficult to hide it from a completely normal person.

Lan Meng was a little unfamiliar, but very professional. He cut open the bionic skin on his knee and cleaned the blackened lubricant inside. The expression on his face was as if he was just massaging his old father's joints.
