After collective discussion, An Ruoxuan and the others have already decided on the next plan. www.biquge.info To put it simply, during the thirty-year journey before reaching Proxima Centauri, the seventeen men on board the spacecraft will take turns on duty. Except for Zhao Gang and An Ruoxuan, who are already forty-five years old, the remaining fifteen people on the spacecraft will take turns to do shallow hibernation and on-the-job duty in groups of five.

As for Zhao Gang, although he is in charge of the main design of the spacecraft, Li Xiaodi can take over his work. Forty-five years old has already passed the peak of a person, and more than ten years can be described as a big challenge for him. Therefore, Zhao Gang will enter a state of deep hibernation, and if nothing else, will only be awakened after reaching Proxima Centauri.

An Ruoxuan has no need to hibernate, although after leaving the solar circle, the dark energy in the universe has become violent, but she can still cultivate normally. If An Ruoxuan was just an ordinary cultivator, she would probably not be able to cultivate now, but she was an ordinary medicine man, and she was an outlier among the medicine people, and the medicine man had some secrets that even Luo Tian didn't know.

An Ruoxuan can feel that her strength is no longer improving all the time, this improvement is all-round, whether it is the strength of the body or the activity of cells, it is no longer imaginable by ordinary people. Although An Ruoxuan also didn't know how long she could live, she had a hunch that two or three hundred years might no longer be the limit of her lifespan.

After this distribution, the first to stay were Anfia, Ivan, Elijah, Wang Ning and James Brown. Everyone else will go into hibernation chambers for shallow hibernation, and if nothing happens, they will be awakened ten years later. The first five people to stay were not chosen randomly, but were decided based on the actual situation.

The next thing the spacecraft has to traverse is the Oort cloud, which is about a light-year, which is a quarter of the journey to Proxima Centauri. The disordered comets and interstellar matter in the Oort Cloud are both unknown dangers and precious treasures for An Ruoxuan and them, and the members they choose must be very cautious.

First of all, Anfia is responsible for the overhaul and maintenance of the photonic equipment on the spacecraft. Photon detection equipment on board spacecraft is an indispensable tool for both astronautics and resource extraction. While the Celestials can also control those devices, they are unable to perform accurate repairs on them.

Ivan is in charge of the ship's laser guard system, and for cosmonautics there are dangers everywhere. Interstellar tiny meteorite fragments, complex asteroid dense areas, unknown civilizations that may be encountered at any time, and the armament system of the spacecraft will always be indispensable.

Although the most powerful weapon on the spaceship is the plasma cannon in charge of Zhang Jianjun, the degree of automation of the plasma cannon is much higher than that of the laser guard system, and An Ruoxuan or the god can use it skillfully. However, the laser guard system is more troublesome, and the laser cannons widely distributed on the surface of the spaceship are not easily repaired by robots.

Ilya is in charge of the ship's engineering robots, which are used to perform simple or dangerous maintenance work on behalf of humans. The engineering robots on the spacecraft are mainly responsible for the maintenance of the external facilities of the spacecraft and the construction of the base when landing on the planet in the future, and some delicate operations still need to be completed by the nanorobots.

The total mass of nanorobots accounts for 15% of the ship's weight, excluding the load of the spacecraft. This rate is already quite high, and it can be said that most of the equipment of the spacecraft is inseparable from nanobots.

As a nanorobotic expert on the spacecraft, James Brown's role is not to be underestimated. The universal nanobot shield on the surface of the spaceship was designed by him, even if the spacecraft was directly hit by an interstellar debris with a diameter of ten meters without protection, that layer of nanobots could directly disassemble the interstellar debris into basic atoms in an instant.

James Brown's designs for nanobots are mostly inspired by different species of ant colonies on Earth, and those weak life forms can burst out with shocking power, which is similar to how similar to nanobots. Out of consideration of the complexity of the journey, An Ruoxuan decided to let him take the first shift.

As for the last Wang Ning, all the hibernation chambers need her to monitor. Although the degree of automation of the hibernation chamber is already very high, it is not human technology after all, and even if there is just a little problem, it needs to be repaired manually. These extremely critical and sophisticated equipment are not something that engineering robots can play with.

Humans have been able to build engineering robots with far more precision than humans, but they are still not as agile as human hands. Even if black technology has created anti-heaven technologies such as gravity generators, it still can't perfectly restore human hands. Nanobots are the key to solving this problem.

But nanobots are more like a panacea, like an emergency product. If the spaceship is damaged, the nanobots can make up for it; The mechanical structure is damaged, and the nanobot can be on top; The body is damaged, and nanobots can be replaced. Nanobots can do anything, but they can't do anything.

If the spaceship is damaged, it will eventually need the biological hull to heal automatically, and the strength of the nanobots is not enough; If the mechanical structure is damaged, it will eventually need to be automatically repaired or replaced with new parts by memory metal, and the tissue strength of nanorobots is far less than that of metal; If the body is damaged, it will eventually need tissue replacement or automatic body repair, and nanobots cannot completely replace the function of tissues.

Is there an all-powerful nanobot? Yes. The nano-metal robot in An Ruoxuan's body can be called all-round, but the cost of that kind of nano-metal robot is too expensive, even for a country. And that kind of all-round nanobot was only designed and manufactured for the human body back then, and it could not be used for other purposes at all.

Machines and equipment will never be omnipotent, and they will never be able to do without human manipulation. Even digital life, which is based on a machine, is inseparable from the guidance of other intelligent lifeforms. There are hierarchical barriers to civilization in science and technology, and if the barriers of civilization cannot be broken, there will be no breakthrough in science.

From the perspective of modern technology, large-scale mechanization and automation have become a trend, and it seems that the role of human beings is constantly being weakened. But in fact, it is only the collective power that is constantly being weakened, and the individual power is becoming more prominent and obvious. With the continuous development of science, what is needed is not large-scale experiments and calculations, but a flash of genius.

The digital life represented by artificial intelligence exists such a problem, although they are already life, but they lack the aura of wisdom. Without this kind of aura, digital life would not be able to overcome the hierarchical barriers in the field of technology. For the sake of its own continuous development, devouring and expanding the scientific and technological achievements of others has become the only way for the development of ownerless digital life.
