12 million square kilometers and 13 million square kilometers, there is an area difference of 1 million square kilometers, and such a large number gap will not be mistaken.

However, this 1 million square kilometers should be counted in the public area, which means that part of the land in this million square kilometers gap should be used as an input construction area, not for planting.

Others have to be abandoned because the terrain is not suitable for planting, after all, although the black soil plain is huge, it also contains mountains and lakes.

After calculating all this, this is an approximate area calculated by the experts, after all, it is impossible to calculate exactly an integer area.

Moreover, they want 15 million square kilometers of land, and in addition to 1,200 usable cultivated areas, the rest will be used to choose suitable places around to build urban transportation sites and so on.

This is also thanks to the continental plate characteristics of Mars, compared to the Earth, the number of islands on Mars is pitiful, and you can count them on your fingers.

The east and west continents are separated by only one strait, and the two continents are connected as a whole, and there are also inland rivers and lakes, but there is no inland sea.

The main thing is that Mars does not occupy 70% of the entire planet's ocean area, which is the biggest difference from Earth in this regard.

Although the surface area of the Earth is larger than that of Mars, the continents of the Earth are smaller than those of Mars.

In addition to the expectation of the black soil, the fact that those geologists fell ill after returning from Mars has made some people's attitudes towards Mars change slightly.

Although Mars is suitable for human habitation, it is still an alien planet after all, especially what happened to these geological experts, which makes some people who are already unhappy stare at this big or small thing.

So the first negative news about Mars quietly appeared on the Internet when people were still talking about Mars.

"There are unknown germs on Mars, and it is possible that humans will be infected in their lives on Mars. ”

Online media basically rely on headlines and current events to attract people, no matter what it is, as long as it can form a topic, they don't care about the authenticity of the content.

As soon as the first check-in came out, all kinds of check-ins spread like a virus on the Internet. And the titles are more thrilling than the other.

What is the existence of a deadly virus on Mars, the Martian virus, humanity or will perish, etc., how to attract people's attention, how to title, how to write content.

This is the time when people pay the most attention to Mars, and every news article about Mars will be clicked on and commented on, and negative news like this will naturally attract more attention.

Naturally, I am skeptical about such news, after all, no one is a fool, there are more people who go to Mars, and there are fewer people who go to Mars through the portal that day?

It is well known that the poet has been to Mars, but no one knows that those geologists have been to Mars!

Besides, the poet anchor is still broadcasting live, how can he be infected by some Martian virus!

Pure!

Of course, even if there is no such thing, there are still many 'experts' in the comment area who analyze it, talking about the harm of unknown bacteria to humans or something, and there are really a bunch of people who believe this.

There is only one reason, Mars is not the Earth! No matter how much it resembles it, it is not the Earth!

As soon as this incident spread on the Internet, it naturally attracted the attention of people from all walks of life.

People who cherish their lives naturally don't want to be infected by the virus if they go to Mars, while curious people go to check the information on their own to see if Mars is the same as what these review gods say.

Anhe City.

Cheng Yuan was accompanying his daughter to do her homework at home, and to be honest, Cheng Yuan looked at her daughter's elementary school math problems like a sharp turn in the brain, and she was also confused.

When he was in elementary school, most of the math problems were simple addition, subtraction, multiplication and division, and the slightly more difficult ones were also more advanced problems.

But now, looking at the stack of thick books next to his daughter's desk, he feels that the country has shouted for so many years to reduce the burden.

Looking at his daughter's serious homework, Cheng Yuan felt a little distressed, perhaps in ordinary families, children can only change their future by studying hard.

He himself was like this at the beginning, but Cheng Yuan didn't need his daughter to use this kind of learning to change his future, he hoped that his daughter could have a broader mind and vision to understand knowledge and society.

At the same time, it can also leave the best memories of her childhood.

At the beginning, he and Guo Xiaolian both threw themselves into the books, because they were both born in ordinary families, so they could only arm themselves with the general trend.

Perhaps with the development of society, such brainteasers-like topics can allow children to think more flexibly, but most of these topics are of little use in life.

However, in terms of education, Cheng Yuan can't blame the other party's good or bad, because education is not about you alone, it needs to be oriented to the whole country!

He can only look at the good or bad of this matter with his own point of view, as well as changing his daughter.

"Yating, should we go to find our mother?" Cheng Yuan picked up his daughter and put it on his lap and asked with a smile.

Cheng Yating first looked at her father, then at the roll spread out on the table, and hesitated: "Is it okay?

"Of course not, Mom must be very happy to see you. Cheng Yuan touched his daughter's head, and the soft hair felt very good to the touch.

"Then let's go find my mother!" Between homework and mother, Cheng Yating chose the latter, and happily reached out to wrap her arms around Cheng Yuan's neck.

After saying hello to his parents, Cheng Yuan took his daughter on the spaceship and flew to the company.

"Boss, your time in Anhe City is getting less and less. Inside the spaceship, Zhang Li first touched Cheng Yating's hair, and then looked at Cheng Yuan helplessly.

Being Cheng Yuan's bodyguard is so easy, sometimes he feels like he has nothing to do all day.

Cheng Yuan hugged his daughter and said with a smile: "No way, the space portal over there in Donghai City is very important, I have to go over, and I will slowly shift my focus to Mars in the future." ”

"Where are we going. Zhang Zhang didn't ask much, and changed the subject.

"In the company. ”

Cheng Yuan's answer was not as unexpected as tension, because Cheng Yuan's previous routes were all at work and home, two points and one line.

When the three of them came to the company, Cheng Yuan took his daughter and walked directly to Guo Xiaolian's office.

I met many company employees along the way, and these employees were more interested in Cheng Yating in Cheng Yuan's arms, because if nothing else, the future technology crystallization company may be handed over to the little girl in Cheng Yuan's arms.

If Cheng Yuan and Guo Xiaolian want a second child, and the second child happens to be a boy, then it will be a boy who inherits the technology crystallization company.

But no matter what happens in the future, the child in Cheng Yuan's arms will not be ordinary. After all, even if the son inherits the family business, the daughter will not get much less.

Cheng Yuan didn't care what his employees thought, as soon as he entered Guo Xiaolian's office, he saw Guo Xiaolian sitting in a chair watching the news with relish.

"Look who's coming!" Cheng Yuan glanced at the holographic screen, and he saw the words 'Martian virus' in sharp eyes, but he didn't care.

"Cheng Yuan!" Guo Xiaolian looked up and found that not only Cheng Yuan, but even her own daughter came.

"Mom!" Cheng Yating shouted immaturely.

"Yating is here for Mom. Guo Xiaolian hurriedly got up and hugged Cheng Yating from Cheng Yuan's hand, and then glanced at Cheng Yuan suspiciously: "Why did you bring Yating over today?"

Cheng Yuan smiled and replied: "It's not that I watch the child's homework so much, it's very hard to write, so I'll take her to play for a while." ”

Guo Xiaolian glanced at Cheng Yuan, although she also felt that it was not good for Yating to have so much homework in elementary school now, but she couldn't be special just because Yating was her daughter.

Her daughter has to write so much homework, and other people's children have to write too, if her daughter can't hand in her homework, what will the other children in the class think?

In the eyes of children, it is very simple, but you can't do what I can do, I am better than you.

However, everyone was brought by Cheng Yuan, and Guo Xiaolian had no choice but to accompany the father and daughter to the playground in the company park.

There are still a lot of people in the company's playground, and although most of them are at work, there are still employees who come here with their families to play.

The three of them played in the playground for an afternoon, and Guo Xiaolian took Cheng Yating, who was tired, to go home first, but before going home, she also told Cheng Yuan about the actions of the state and the negative news circulating on the Internet.

The action on the national side is very simple, Hua Lao has decided to send soldiers and some scientific researchers who have used genetic enhancers to Mars after the National Day.

Although the geologists got sick when they came back from Mars, they recovered immediately after using the genetic enhancer, which is something that no one is blind enough to see at a glance.

Besides, with Cheng Yuan, a benchmark who is fine in and out, it is almost impossible to think about it to understand why those geological experts fell ill.

The physical condition is too poor to adapt to the Martian environment!

It's just that the physical condition will naturally not hinder the development of Mars, so things will go step by step according to the original plan.

As for the negative impact on the Internet, neither Cheng Yuan nor Hua Lao cares.

This unfounded claim will soon be broken. However, the state is still ready to send more relevant personnel to Mars to collect water, soil and air for detailed testing.

Mars is not the Earth after all, no matter how suitable it is, there will definitely be places different from the Earth, what kind of harm will the bacteria that breed on Mars itself bring to humans, and how to solve it, which must be prevented.

Another point is that what will happen to the bacteria that are carried to Mars by humans themselves, and what will affect people themselves, they need to prepare countermeasures in advance.

Therefore, going from one planet to another is not so simple, and it is necessary to take into account all aspects, otherwise it is very likely that negligence will lead to danger.
