After inspecting the ecological construction of Mars, Qin Yi also has a bottom in his heart, it is much better than he imagined, too much, the ocean of Mars has basically formed a complete ecological chain, and the rest is only to continue to replenish more organisms that can adapt to the freshwater of Mars.

The land of Mars, the vegetation has been fully covered, and the next step is to slowly put more animals to Mars, and at the same time, according to the latitude and longitude and humidity on the Middle-earth continent of Mars, slowly create tropical rainforests, temperate broad-leaved forests, cold coniferous forests and other cradles of life.

This process may take a long time, especially for animals from Earth, and after being introduced to Mars, it needs to be adapted.

First of all, herbivores have to adapt to the environment of Mars, and be able to slowly reproduce on Mars on their own, this process alone, Qin Yi estimates that it will take at least a few years.

If the number of races is to expand to a certain base, it will take longer, especially for advanced animals, its reproduction rate is very slow, cattle, sheep and horses, these animals, can only reproduce one litter a year, and a litter is generally only one, the reproduction speed of dogs and pigs is relatively fast, but it is also almost able to give birth to one litter a year, the number is relatively large, as for elephants, giraffes, etc., its reproduction cycle is longer, the maturity period is many years, and only one litter can be born in a few years.

Advanced animals have a long reproductive cycle and a small number of offspring, and if the population wants to expand to a certain size, it needs to be caused by a large number from this side of the earth, but more importantly, it takes time.

When the herbivores have almost multiplied to a certain extent, then the carnivores, and the reproduction of carnivores will be even slower, even if it is the fastest wolf, hyena, African wild dog, etc., its reproduction speed will not be too fast, as for tigers and lions, it will be even slower.

For the entire ecology to be completed, Qin Yi estimates that it will be at least several decades, and as for the real formation of a stable ecological chain on Mars, it is difficult to say that this process may take hundreds of years.

Animals are not more advanced than plants, although animals are more advanced than plants, but their adaptability is weaker, the rate of reproduction is slower, and it takes a long process to slowly reproduce and grow.

Back on the 'Han Wu Emperor' spacecraft in Martian space, this huge spaceship has now become the super base of Galaxy Technology Group stationed on Mars.

There are more than 200,000 scientists, engineers, astronauts, ordinary employees, etc. of Galaxy Technology Group on Mars, all of whom live and live on this huge spacecraft, and work on Mars or in outer space on Mars.

Huge space farms have been built in outer space on Mars, producing enough vegetables, fruits, and grain to meet the needs of millions of people; There are also space smelting factories, asteroids mined from the asteroid belt, which are constantly being smelted and used to build space factories.

Even Qin Yi asked Yang Hongyan to start building a new space spaceship factory on the Martian side, and is preparing for a full transfer to Mars in the future.

The 'Emperor of Han' spacecraft has many layers, and the functions of each layer are different, some are research centers of various disciplines, some are living and entertainment areas, and some can be used for agricultural planting, and the agricultural area on the 'Emperor of Hanwu' spaceship alone can produce a large amount of grain, fruits, vegetables, and so on.

It's a spaceship that can be used for interstellar colonization, and everything is fully equipped.

On one of the floors, Liu Peiqiang, Lu Qingwei, Wang Songling, Liu Daoming, Li Jingxuan and other high-level executives of Galaxy Technology Group and scientists from the Academy of Sciences gathered together and seemed to be discussing something with each other about the Martian Middle-earth continent.

"I think this first city should be placed in the outlet sea of the small Yangtze River, this location is in the temperate zone of Mars, the climate is pleasant, the terrain is very open, but also by the sea, the river, the water resources are very rich, very suitable for building a huge city, even the name I have thought of, do you want to listen to it?"

Lu Qingwei pointed to a river estuary on the map of Middle-earth on Mars and said.

"Don't, don't, don't you say we all know what name you've got."

When the others heard this, they immediately shook their heads one by one, everyone knows very well the level of Lu Qingwei's name, a thousand pieces, no matter what it is, all of them are called Qingwei.

"This location is very good, but in the future, we don't need to consider the problem of Mars transportation, and now the earth's private anti-gravity vehicles have been popularized, so this transportation does not need to be considered."

"We need to consider the environment, climate, water use and topography, and the equatorial region is too hot and will be built into a huge pristine rainforest in the future, so we can exclude these areas."

"As for the cold zone, it is too cold and not good, and it will cause a lot of inconvenience to our lives, so it is better to choose to build in a temperate zone."

"The topography of this Middle-earth continent is actually relatively simple, high in the middle, low on all sides, and vast plains, what needs to be considered is the problem of water use, a huge city uses a lot of water, so it is necessary to choose an area with water."

Liu Peiqiang looked at the map of Middle-earth, pointed to the areas on it and kept eliminating them, slowly locking the areas within several ranges.

"I think this first city was built in the middle reaches of the Yangtze River, which is close to the river, rich in water resources, open terrain, and more importantly, this area is very stable according to our early geological exploration."

"In the southern region, there is also a relatively tall mountain range that can block the cold current from the Antarctic region, which is very suitable for building a city."

"No, no, I still think it's better here at the mouth of the Yangtze River, you think, now many of the big cities on the earth are by the sea, and there are many benefits of relying on the sea."

When Lu Qingwei heard this, he shook his head again and again and expressed his opposition.

"How's your discussion?"

At this time, Qin Yi walked in, and when he saw that everyone was gathered together, the argument was more intense, so he also hurriedly looked over.

"We are discussing that it is better to build the first Martian city in that place on Mars, Qingwei said that it should be built at the mouth of the small Yangtze River, I think it should be built in the middle reaches of the small Yangtze River, Wang Songling thinks it is better to build it in the Handong Plain, and Liu Daoming They think the Hanxi Plain is also good."

"I see, it's better for you to decide to go, boss."

Liu Peiqiang smiled and pointed to the places on the Middle Earth Continent and said.

"You can build anywhere, anyway, when we get more populous, we will definitely build more and more cities, and I think what we should all discuss is how to plan this city."

Qin Yi looked at the map of the Middle-earth Continent, then looked at the dots marked on it, thought about it and said.

To be honest, for Qin Yi, it is the same wherever he builds, and now fighting for it is just a happy trouble, which is like having money, thinking about whether to buy a house or a car first, no matter what he buys, it must be happiness.

The question that really made Qin Yi think was how to plan the city on Mars, which was really worth thinking about.

The Martian continent of Middle-earth has nearly 80 million square kilometers, which belongs to the Galaxy Technology Group, and it is foreseeable that for a long time in the future, the population of Mars will be very sparse, which is truly vast and sparsely populated.

The land is vast and sparsely populated, and this Mars is now like a blank sheet of paper, if you want to draw a beautiful picture, you must naturally plan well from the beginning, and you can't start randomly.

"When it comes to urban planning, our opinions are relatively unanimous."

Liu Peiqiang and the people around him looked at each other, smiled and said.

"Oh?"

Qin Yi was slightly surprised, there was a lot of competition for where to build the first city, but he didn't expect that an agreement had been reached on this urban planning, which made Qin Yi very curious, and said, "Hurry up and listen to it." ”

"In terms of urban planning and construction of Mars in the future, we are ready to refer to the urban planning of European and American countries."

Liu Peiqiang nodded, and then with a movement of his mind, the virtual watch was connected to the computer control system in this hall, and the projector was automatically turned on and began to play a city design map.

"In the future, our cities on Mars, we are going to only retain the functions of living, entertainment and office, and as for industrial production, all will be moved out of the urban area, either to build an industrial city or set up in space."

"In terms of urban planning, in the middle of the city, we are going to set up government office areas, banks, company office areas, etc., and this area is mainly dominated by high-rise buildings."

"Around the city is a huge residential area, we refer to the way of North American countries, all the residential areas are built villas, the back is the garden and the front is the lawn, the area is controlled at 1,000 square meters."

"Here in the residential area, for every certain number of residential areas, we build a primary school, a certain number of primary schools build a secondary school, and a city builds a university."

"And the size of the whole city, we control the size of the million people, once the population exceeds one million, we will build new cities, and move the excess population to the new cities."

With Liu Peiqiang's explanation, the planning map of a city was slowly played, and each area was constantly divided, such as residential areas, living areas, entertainment areas, education, medical care, office, etc., the planning was very detailed, and a city that could accommodate a million people appeared in front of everyone's eyes.
