The scientific basis should be genetic modification, and people will choose plants that suit their tastes and cultivate them again.

If something that does not meet people's tastes, that is, something unpalatable, they will disappear.

According to geography textbooks, the tropics have the most heat given to the earth by sunlight, so the places with more sunlight actually have the most animals and plants that can live.

And in this place, it is not the most extreme climate, the most extreme climate, but in the desert area, if you want to say that a single square kilometer, the place that can survive the most life, the tropics must be firmly in the front.

It is estimated that there are only stupid Europeans who think that tropical places are not suitable for people and crops, and for Europeans, as long as the temperature is not suitable for their survival, then it is not suitable for animals and plants to survive.

For those who have a purpose, life will be better than for those who have no purpose.

Qian Rujun saw that the students on Xuetang Island were so busy that he had to find a purpose for himself.

Even if she had to leave, she couldn't put all the students on Xuetang Island here, because they knew that following Qian Rujun was the most important thing.

Until now, Qian Rujun didn't know if they regarded her as a little baby who couldn't be thrown away.

If Qian Rujun was constantly dangling in front of their eyes, even if he disappeared for a day or two, they would not notice.

As long as one or two of them can know where Qian Rujun is, they can continue to do their work with peace of mind.

It's like being taken care of by an adult for their little baby.

Normally, even if you don't see it, it doesn't matter, but when you find out that it's gone, you'll be very alarmed.

In the 21st century, the tropics are one of the places that are most able to maintain their pristine mysteries.

In the eyes of the students of Xuetang Island, although this place is mysterious, it is not impossible to break through, and in their eyes, these difficulties will not cause obstacles for them to move forward.

At least, there are still many students on Gakudo Island, who are on the front lines of the war, constantly gathering the humans of Borneo to the city of Sunlight that they founded.

Although the people of this place have relatively large antibodies to the diseases of this place, it is obvious that there are still not so many people in this place.

Although it is said that when people are poor and bored, they are probably busy giving birth to children, but this place still does not have so much enthusiasm for taking care of children.

Because taking care of children is actually a very painful and busy thing for human beings.

In most cases, they leave their children in nature and left to fend for themselves.

It's very good to give birth, they will let the child grow up automatically, so when the children in this place grow up, they don't pay so much attention to the care of the elderly.

Because for them, many of them are born and raised, and they don't respect the tradition of old-age care.

Perhaps, this is how the tradition is established, and the people in this place are willing to work as much as the child will pay, so the tradition is gradually formed.

Dahan's attention to children and future generations cannot be compared anywhere else.

"Princess, you said you wanted to go to the rainforest to see what kind of place each place was, how many people would you bring, how many people would we send with you?"

"I want to go alone, all of them are gone, all of you here have a purpose, and you all need to work for your Sunshine City.

You dare not command me to work for you. I'm idle enough, so I'm supposed to walk around.

Maybe you can see someone who can help you drive them over.

The only thing that people in this place believe most about people in other places is that they believe in the gods, that additional calamities will come upon them, and if they don't come, then I will send additional calamities on behalf of the heavens.

In this case, they will listen to you.

I will tell them that Nikko City is a peaceful place.

In fact, here, although their lives do not seem to be much different, and they have lost their freedom, if they live for a long time, they will know that their lives are progressive. ”

In fact, everyone knows that Qian Rujun very much wants to move around alone, and after a long time, he will naturally think of the students of Xuetang Island.

But in most cases, because it was too dangerous, they were reluctant to leave Qian Rujun too far away.

But on this island, they didn't feel too dangerous, although nature is full of large animals, and even crocodiles, but for Qian Rujun, crocodiles are not such dangerous things at all, but to her are a toy.

So they didn't have so much backlash against Qian Rujun's request to walk around, because they couldn't take good care of Qian Rujun.

Now many things are still under construction, and this Qian Rujun lives in construction, and it is not so comfortable.

Let Qian Rujun live on the boat, they also feel that this is abusing Qian Rujun.

Qian Rujun has already left a contact box in Sunshine City, and they can get Qian Rujun's contact at any time, of course, this Qian Rujun's contact refers to passive contact, not active contact.

But they can also put what they want to say to Qian Rujun in the box, and Qian Rujun will pay attention to it at any time.

"Princess, at least one person is around, right?"

If Qian Rujun wasn't around, they wouldn't be able to stay in the space at night, and they wouldn't have so much time to use.

It was also a bit of a pity for the students of the academy, but they knew that Qian Rujun hoped that they would be able to build the city by themselves without being influenced by her, so they hoped that they would achieve these things independently.

But Qian Rujun is by his side, they always want to rely on Qian Rujun to do this, many times they will go into the space to think, and then think well before coming out to do things.

But in real time, how can they have so much time to think?

So after Qian Rujun left, they couldn't take advantage of this condition.

If Qian Rujun knew what they were thinking, he would probably laugh and tell them that they were thinking too much.

However, Qian Rujun knew that even if she said so, they might not necessarily believe it, because many things are like that when you think about it.

It's a pity that Qian Rujun's brain may look different from others, and he often thinks differently from others.

Qian Rujun set off, she didn't walk on the road when she set off, slowly moving forward but flying in the sky that everyone could see.

She had to let the people here know that the students of School Island were covered by her.

If you oppose the students of the school, you are against her.

In the age of science, there was faith everywhere, and their beliefs may or may not be pious, or they may be fearful, but faith exists, no matter who they worship.

Qian Rujun doesn't have to tell them what she is, as long as they imagine that she is an irresistible force for them, that's fine, not to mention that if they specifically point out what they are, maybe they will be able to judge whether Qian Rujun is dangerous or not in their minds.

He knows how dangerous you are, and he will think about how to oppose your methods according to your danger.

And after this kind of thinking, after many attempts, it is really possible to succeed.

The purpose of Qian Rujun's flight away from the students on Xuetang Island was to make it visible to others, and after flying a certain distance, Qian Rujun basically began to have a jumping style in order to enjoy the feeling of passing by the scenery.

Sometimes she would stand on the top of a tree and look at the scenery, and sometimes she would go down to the bottom to walk.

The main thing is to see where the scenery is good.

Qian Rujun doesn't need to take care of the sailors with her, she seems to be very free, and as for the food she needs, all the food she needs is collected in the space.

What's more, even if it is random and delicious grouper cod, she has prepared a lot of it in the space and can take it out and eat it at any time.

So she had no luggage on her except clothes. This is the lightest way to travel.

used the space points to exchange for a piece of snow in the space, with this piece of snow, Qian Rujun finally had a place to hide, and after refrigeration, Qian Rujun didn't feel so awkward to eat.

Maybe Qian Rujun is too influenced by modern life, if she goes beyond modern life, she will have a lot of thinking inertia, and these thinking inertia will make his emotions good or bad, which Qian Rujun has no way to change.

Maybe it's because the ancients didn't have many things to remember, so their memory is actually better than you think, especially these weird things, which can often make them remember for a long time.

Qian Rujun believes that this period of time is estimated to allow them to maintain their memories for a very long time, until they complete the new construction of Sunshine City.

In the early stage, they are almost demolition, but the more they dismantle the more things they learn, and in the later stage, they basically don't need such gradual guidance, as long as they are told what to do, they can do something, this is their run-in period, and they are not in a hurry.

On the way, Qian Rujun saw a little girl alone in foraging, her way of foraging was not to fight and kill with the animals, but to look for something to eat in the tree, to see her very clever to run to the mountain, sometimes when she saw a carnivore, she would run to the tree within twenty seconds in one breath.

But there were no more adult objects around the girl.

Qian Rujun has finally understood the local dialect under the guidance of the students of Xuetang Island during this time, and living in this place, if she can't understand the local language, she doesn't know what they are saying in front of her behind her back, which is also very awkward for learning Qian Rujun.

If it weren't for wanting to learn to understand the local area, Qian Rujun wouldn't have endured so long in Sunshine City, boring days, after all, she has something to do if she has to study, so life is still very good.

Every day, learn the local language, drink tea, chat, take a walk outside, exercise, and train your language skills by the way.

That's Qian Rujun's way of life these days, as for the sailors, she has long been handed over to the students of Xuetang Island to arrange, and she can do whatever she wants, and even she hasn't seen the existence of sailors for a while.

It is estimated that they have been sent out to search for other places, and there are no people who can use them.

The gathering of the population is more convenient in the era of industrialization in later generations, convenient to manage, convenient to do public facilities, and public facilities will not have signs of waste, after all, there are more people using a road, and the average cost is low. As long as you plan well in advance, you will not increase the cost of building a road after the fact.

However, in this era, if you want to create a populated area and let people out of agricultural life, the most important problem is to solve the food problem.

If there is not enough surplus food in the area, it will be a great test for those who have left the agricultural life.

Because they will be at any time, because there is no food, and they must wage war to get food.

In this way, the city will become a conqueror in this place, and will be hated by everyone instead of welcome.

Although the fruit trees in that place are very dense, and fruits can be picked and eaten everywhere, no matter what, the degree of land use is relatively low-density, and no matter how much fruit there is, there is not as much food as the amount of food provided by human cultivation.

So when the city is bigger and the more food needs to be gathered, the demand for transportation, the demand for grain reclamation is formed.

But the students of Gakudo Island don't seem to see them in charge of farming for a while.

It's just that everyone is constantly building new projects and gathering people.

Later, Qian Rujun couldn't help it, and asked the students in the school to find out that they were not going to farm in the first year.

However, they were aware of the need for food, and even they worked very hard to build ships during this time, and sent sailors out with men to collect grain in various places, and they hoped that this stage would concentrate as much as possible on the new cities, and the second stage was when they began to produce food.

He knew that he had to study how to make the food in this place be able to be produced, and it would not be the same as the big man.

And he couldn't use the farming methods of the Great Han in this place.

Of course, after the approval of Qian Rujun, some methods of land fertilization can be applied to this place.

One of the good things about Borneo is that it is ready to be cultivated. The growth rate is still very fast.

The biggest problem is that the people of this place are very unaccustomed to labor and work, and their habits are more difficult to disperse in the same way.

If they do it, they will use lazy ways to farm, so although the grain that can be produced by the same land area seems to be about the same as the grain production of the Han Dynasty, but in fact, the grain production of this place can actually be doubled and even according to Qian Rujun, the grain production of the Han Dynasty is actually very low.

With the effort to cultivate rationally, it is not a problem for Borneo to increase dozens of times.
