"Princess, is it really necessary for us to leave?

The students of Xuetang Island noticed that Qian Rujun was sorting out the projects left behind by the Han Dynasty and preparing to travel far away.

To be honest, they are still a little nostalgic for the land of Dahan, after all, this is where they were born and raised, and they don't know how long they will leave after leaving this time, if the princess never comes back, then they may have to say goodbye to Dahan forever.

Thinking about the big man who wasn't very cute in the first place, the land has become very cute, which makes them a little nostalgic.

So some people can't help but ask such words, of course, there are still very big differences in the personalities of students on Xuetang Island, some people are more aggressive, some people are more conservative, some people are more nostalgic, and these positive and enterprising people, or hope that the princess can go to a new place to expand their horizons, after all, the princess expands her horizons, in fact, it is more to expand their own horizons.

In the end, especially those who are more interested in geography, they will want to see the wonderful scenery of the world, Qian Rujun did not introduce some cities to them, after all, these people do not exist in the present world, if they are read, they may give them the wrong impression.

But as long as the books related to geography, even if they introduce natural mountains and rivers, they will more or less mention nearby cities, and they can still find that the knowledge they have does not actually belong to the Han Dynasty, but comes from an inexplicable dynasty that is inexplicably consistent with the Han dynasty, but there are many inconsistencies.

There are so many things they feel are wrong.

"You haven't left Dahan yet, you start to miss your hometown, if you start to miss your hometown now, it's better to stay in Dahan, I don't want to take all of you away, if you really want to stay, you can actually stay in Borneo so that you miss your hometown and can go back at any time." Aren't there regular flights between Borneo and Golden Wheat City?"

These Xuetang Island students stopped talking, in fact, the reason why they didn't want to leave Qian Rujun was really very simple, because by Qian Rujun's side, they could enjoy countless hours.

But if they leave Qian Rujun, the time will be shortened a lot, at least nine-tenths shortened, and if their lives are ten times more and they have more possibilities, in fact, there will be more things that can be developed for smart people like them.

Now in the space, they have a lot of things that can't be taken out and applied, because they have modern scientific knowledge, so they can make things and research and development things are very much, and even they have studied a lot of products beyond the present, and in the space, whether it is water or electricity or various industrial facilities, Qian Rujun did not restrict them to make them, so what they made is not only lathes.

However, they don't have the ability to bring these implements out.

It is impossible to make such a thing with the abilities and materials of the outside world.

Almost all kinds of things that can be thought of can be developed, and the most surprising thing is that they can actually develop the Internet, as well as mobile phones, but they can't be used out, because there is no so-called base station in the outside world, and they can only make and use the base station in the space.

In fact, Qian Rujun was also very surprised, their manufacturing capacity, it seems that they know that they can't make successfully, in fact, it is the lack of mechanical equipment, so they developed a program to see what programs are needed for the manufacture of each thing, and began to manufacture the initial equipment, so that they can make more accurate tools step by step, and by now, Xuetang Island students have been able to manufacture very accurate lathes and even automated equipment.

The water in the space is used by them in large quantities to generate electricity and carry out various electrolysis applications, and there are only more than 2,700 people in the space, and these people use the resources in the space very easily.

For them, Qian Rujun's space world has no end in sight, and the Zizhu Lake space next to them has also expanded a lot, and it is slowly combined with the space, because now the space has been able to allow ordinary animals to live in it, so the Zizhu Lake space and the space connection space have slowly combined without being in a state of separation.

The great changes in space seem to have told Qian Rujun that she can already move to another world, which means that she has lost the resistance to walk elsewhere.

Even if they want to use scientific tools, with the efforts of the students of Xuetang Island, some of them have been able to practice, after all, at least if they want to contact in the outside world, they can now use the radio system, the radio system, as long as there are two machines can communicate with each other, unlike mobile phones, which also need to have a base station, in order to realize the desire to communicate, in fact, when they developed the radio, in fact, they were also very surprised, it turned out that such a simple thing could achieve the method of communication.

In fact, when they were initially able to contact the radio, the communication distance was not very far away, but they had a very good time, in fact, the simplest use of two cylinders, a line can transmit the sound, but the wireless does not need to pass through a line for them, such a thing as radio wave conduction brings them a very surprising reaction.

Many students on Gakudo Island have invested in the development of radio waves.

"Is it true that the princess radio system can't be transmitted? It's really very useful, if we can talk in a distant place, we have a stronger ability to control the place. ”

"It's not that you don't know, the radio you are making now has a distance limit, there is no way to go from one city to another, and you can communicate through the radio, if you can communicate through the radio, in fact, you can already control the world, because as long as each city is ready for a person to receive, the message conveys the message, you can come to sell the news, more than everyone, but when everyone can grasp the information in this way, the news is not so precious, but these are not the point, you want to spread this thing, what is it for？

Have you ever wondered if they want to make this thing now, do you have to spread more things to them so they can make it?

Everything is the result of your research using the books in the space, and if you give them the opportunity to improve slowly, maybe they will miss something, and there will be one less thing in their technological development in the future.

We've given them more time and more manpower to invest in technology, and if these guests don't have something to develop, they're going to get lazy, so give them the opportunity, at most you give them a little bit of imagination.

Let them see how you use radio systems, but you can't teach them how to make radio systems, as long as they know that such things exist, they will be targeted.

As long as these things exist in their memories and are not destroyed, sooner or later they will make them, maybe they will make something different from what you have made, because they may have problems that you have not encountered, so they can trigger their imagination and improve such things.

You must know that text is the largest medium for knowledge dissemination, but it is very difficult to find out if you want to write down your own knowledge, and it often takes a lot of time to collect your own knowledge, but when you save the time you spend, people's progress will become very great.

Perhaps in the future generations, many people will be able to easily do what geniuses like you can do.

Everyone's brain has a lot of memories, but they can't use it proficiently!"

For the first time, Qian Rujun did not ignore their efforts, but expressed her opinion, in fact, only she knew that if there were not many things in the way, in fact, what the students of Xuetang Island had broken through had surpassed the future generations, and if there was a computer, maybe they would be even more different.

"Actually, your research direction is a bit wrong, if you study things like computers earlier, many of your research problems will be solved by computers, because the amount of knowledge that can be derived from computers connected to the network is really too large, which will be very helpful to you. ”

Qian Rujun knew that the students of Xuetang Island were researching new things from time to time.

If they don't, they'll all feel uncomfortable.

A challenge is not a challenge at all for them.

Qian Rujun wants to travel around the world, now there is a very different concept from before, he now wants to travel around the world, he can eat well, wear well, live well, and even directly let them build a house from the space, move directly to live outside, enjoy the wind and sand outside, enjoy the wind and sand outside, and enjoy the wind outside is completely different from before, they used to want to go all the way, sleep on the streets all the way, and face the attack of wild beasts, so the existence of students on Xuetang Island was really just Qian Rujun's guard.

But now Qian Rujun has no way to treat the students of Xuetang Island as guards, when their abilities are getting stronger and stronger, and each of them can become his teacher, Qian Rujun also smiled a little bitterly, if they don't give them something to use their brains, maybe they will become stupid, maybe they will be lazy, and such a smart person, if they are stupid and let them be lazy, then it is a very big waste for the world.

If Qian Rujun had not forbidden their research on science and technology, perhaps the students of Xuetang Island would have gone beyond the research of the twentieth century, and even Qian Rujun might not be able to understand what they were studying.

In fact, now Qian Rujun can't understand it, some books are equivalent to heavenly books with words to him, and he can't understand them at all.

But the students of Xuetang Island can actually understand, thinking that Qian Rujun is the real person of the later generations, and the students of Xuetang Island are just slowly expanding their knowledge step by step, and they have mastered the knowledge of later generations, but now some of the students of Xuetang Island have begun to surpass the future generations, which makes her feel unimaginable, but they have been in the space for ten more years, and they have only one hundred years more, and the changes in people can be so big, but Qian Rujun thought that when the people in Southeast Asia encountered the westerly wind and the eastward wind, they were with the Europeans, and the changes in thinking given to them by the Europeans were indeed beyond a thousand yearsThe accumulation of Europeans is actually constantly drawing nutrients from the East and proposing their own culture, perhaps because they are facing too many new worlds, which makes them eager to have a new understanding of the new world, and the understanding of the world in all aspects has promoted their scientific achievements.

Qian Rujun thinks that when he takes the students of Xuetang Island to start traveling around the world, they see more people from all over the world, people with different skin, different hair colors, and people who live in igloos like wild beasts, maybe the students of Xuetang Island will also start to expand their horizons.

It's just that the appearance of these people is a little different from what is recorded in the book, at least it will not be so clean after that, in this era, the problem of cleanliness has been a problem that has been difficult to solve for a long time, in fact, the biggest problem still comes from water resources, which is not so easy for them to solve.

I don't know what era began to build reservoirs, with reservoirs, and the construction of tap water, people's lives began to pay attention to cleanliness, and began to avoid some diseases, quiet life, can avoid some infectious diseases, perhaps this is also because Europe encountered the plague, and in the fight against the plague, slowly gained some wisdom, and began to use these wisdom in later generations to take care of their own environment.

If, like China, they had the same methods as China to combat the scale of the disaster, and there was no way to do it on a large scale, perhaps they would not have tried to extinguish the plague.

Most of the Chinese do not have the freedom to move, and in the absence of freedom of movement, no matter what kind of disaster, it often occurs in small places, unless the disaster comes from global weather changes.

If it is a change in the global weather, human beings can only continue to adapt, and continue to survive from the adaptation environment, in fact, every climate change brings about the process of the migration of the grassland peoples and the southward migration of the grassland peoples is a very serious problem for the entire Han Dynasty, now the Huns have been controlled, but soon the grasslands will be filled with more people with freedom of movement, unless the people who live in the grasslands have the courage to block their progress.

In fact, why didn't Qian Rujun completely turn the grassland people into an agricultural people and maintain a certain amount of force so that they could block the power of the new immigrants.
