Li Qingye's Mars expedition is not over.

After an inspection of the twin neutron manufacturing plant of the Vulcan Ring System, he was accompanied by Dr. Yuri to Utopia City in the northern hemisphere of Mars.

Utopia City, located in the southern part of the Utopia Plains, is also one of the landmark cities of Mars and the largest city on Mars.

However, the city is unmanned, and there is not a single real human presence here except for synchronous robots and industrial robots.

This is also the urban norm of Homo sapiens on other planets, natural satellites, and asteroids.

At present, among the planetary colonies of mankind, only the permanent population of Venus has exceeded 5.33 million, and the permanent population of other planetary colonies is generally around tens of thousands.

However, Homo sapiens has found two other planets suitable for human habitation.

That is Saturn and Neptune.

Why these two planets?

The reason is naturally very simple – gravity.

Saturn's gravity is 12.5G, Neptune's gravity is 11.4G, which is very close to Earth's 9.8G.

Planetary gravity has a very peculiar characteristic, the gravity on the surface of the planet is often the largest, and it will show a decreasing state towards the earth's core or beyond the atmosphere.

In this way, as long as the 9.8G gravity layer is found outside the atmospheres of Saturn and Neptune, then Homo sapiens can build a suitable artificial ecosystem in this gravity layer.

You know, Saturn and Neptune have a very large surface area.

Even a small part of it would be enough for tens of billions of people to live.

Now Homo sapiens is not a lack of resources, but a lack of suitable living space.

Although in the future, the new human beings will definitely have to modify their genes and become new human beings in the universe.

But Li Qingye also knows very well that the rice must be eaten one bite at a time, otherwise it is easy to choke to death.

Even according to the most optimistic schedule of the Science Division, it will take at least 150 years for new humans to complete genetic modification and full evolution.

This is still under the premise that Homo sapiens has absorbed a large number of technologies from the intelligent machine civilization.

If you don't get the scientific and technological database of the intelligent machine civilization, then this time may increase several times.

In fact, the development speed of Homo sapiens is already very fast among all levels of civilization.

Referring to the six-claw civilization, the other party has developed for hundreds of thousands of years, and its overall technical level is much worse than that of Homo sapiens, even if it does not obtain the relevant technology of the six-claw civilization and the intelligent machine civilization, the comprehensive level of the Homo sapiens company is still slightly higher than the six-claw civilization.

The current shortcoming of Homo sapiens is that it cannot survive outside the standard gravity zone for a long time.

And this problem, even the extremely smart Li Qingye, has no way to solve it in a short time.

This is mainly because there is no room for casualty and negligence when it comes to genetic issues.

If the transformation route goes wrong, it will be a huge setback for both Homo sapiens and the new humans.

Therefore, Li Qingye would rather take his time, spend one or two hundred years slowly debugging and experimenting, find out all the possible problems, and put the last step in place.

The disadvantage of this is that the living space of new human beings will be seriously insufficient.

You know, with the skyrocketing life expectancy of new humans, coupled with Homo sapiens' continuous encouragement of childbearing, the current annual natural population growth rate of Homo sapiens has reached a very exaggerated 8.3%.

Since the beginning of Galaxy 13, the scale of natural people on the other side of the earth flowing into Homo sapiens has dropped to only a few hundred thousand per year.

But the total population of Homo sapiens is still in Galaxy for 20 years, exceeding 5.6 billion.

It is estimated that in the next 200 years, the total population of Homo sapiens will exceed one trillion.

Obviously, the earth can't accommodate a trillion new human beings, and even if the rest of the free world territory is eaten, it won't help.

The earth's ecological environment, at its limit, can only accommodate 500 billion human beings, even according to the technological level and productivity of Homo sapiens.

But this is clearly not the outcome that Homo sapiens wants to see.

After all, 500 billion people are crammed into the earth, and the picture is terrifying to think about.

Venus is the first habitable planet modified by Homo sapiens and is expected to accommodate 5 billion new humans.

But that's not enough.

The new human race also needs a broader living space.

After a series of research, coupled with the fact that Homo sapiens has obtained a large amount of technology from the intelligent machine civilization, the company's level of terraforming has skyrocketed.

Now Homo sapiens has the confidence to transform Saturn and Neptune.

The principle of transformation is similar to that of Venus, which is to use vacuum carbon balls to build floating land, then build a honeycomb structure on the surface of the planet, and finally extend outward to the 9.8G gravity layer based on the honeycomb structure layer, and build a habitable area in the 9.8G gravity layer.

And the hive layer can also mine the bases of Saturn and Neptune.

As long as the modification of Saturn and Neptune is completed, the 9.8G gravity layer of these two planets is enough to accommodate trillions of new human beings.

If that's not enough, then Homo sapiens can only transform Jupiter again.

As for Uranus, the planet's gravity is a little lower than Venus's and is not suitable as a habitable planet.

Li Qingye and the management of Homo sapiens had a very simple idea, as long as the problem of population living space for nearly 200 years was solved, there would be no big problem after that.

Because after 200 years, the new humans have most likely completed their evolution, from the new humans on the earth to the new humans in the universe.

The characteristic of the new human beings in the universe is that they can survive for a long time in an environment of microgravity or tens of gigabytes of gravity, and are not affected by gravity.

As long as you become a new human in the universe, there is no need to consider specific gravity at that time, and the entire universe is a habitable area for new humans.

Li Qingye's evolutionary route for the new human race is also the first and two big, and now he can only rely on time to grind it slowly little by little.

This kind of thing is not to be rushed.

If you rush too much for quick success, it is likely to backfire.

The reason why he recently went to various colonial planets to investigate was actually to arrange various engineering and scientific research projects, so as to prevent people from being too eager for quick success.

In fact, Li Qingye knew that many researchers were anxious, not because they were for fame and fortune, but because they were also eager to complete their evolution and become new humans in the universe who could live freely in the universe.

However, scientific research work is sometimes slow and meticulous.

He constantly inspected various scientific research and engineering projects, found many problems, and seriously criticized those behaviors that were eager for quick success.

Now the company does not need to be too anxious, but to concentrate on absorbing the technology of the six-claw civilization and the intelligent machine civilization, and consolidate the company's foundation, which is the current top priority.

As for completing evolution, that is the hundred-year task of Homo sapiens, and there is basically no need to think about it in one or two hundred years.
