Materials have always been the biggest constraint on human development.

After all, many times, people's imagination is limitless. In many science fiction films, people have long thought of those high-tech, but in reality, if you want to create them, the biggest constraint is all kinds of materials.

And after all, the elements of the earth are limited, and many things do not exist on the earth, or only exist in a few places with harsh environments.

For example, some inaccessible deep mountains, and some deep oceans.

There are even many places on Earth that do not exist at all. This is also the reason why those big countries are now vigorously developing space technology. Because they want to go out of Earth and find more resources on other planets.

And whoever takes this step first is destined to have more opportunities than other countries.

For a long time, in this regard, it has also been the United States that has come to the forefront.

The first to land on the moon was also a native of the United States. God knows if they brought something back from the moon.

As for the news on the Internet, it is just the news that they want others to know. The real core, they are impossible to reveal to outsiders, even after so many years.

And the last time the moon was not easy, even if it was a big business like the United States, it couldn't let them visit the moon frequently. Even in recent decades, no man has ever been on the moon.

And the Wulin Continent is completely an independent world, a world that is very different from the earth, so in the Wulin Continent, of course, there will be many special elements.

And this can be seen from the big difference between the chemical element table of the Wulin Continent and the chemical element table of the earth.

And Hua-Xia relied on these elements that did not exist on the earth, or existed in small quantities, to make a lot of incredible things.

Well, these are all done by those scientists, and Li Qingyun is actually not very clear.

Because Li Qingyun never cared. No matter how good they are, what can they do? No matter how many hundred years of development of their weapons, it is impossible to hurt Li Qingyun.

But if it continues to develop like this, it will not be difficult for Hua-Xia to catch up with and surpass the United States.

And all this can be said to have been brought by Li Qingyun.

If it weren't for Li Qingyun opening up the Martial Arts Continent to Hua-Xia, there wouldn't have been so many changes, and if he hadn't let Hua-Xia take the resources of the Martial Arts Continent outside, Hua-Xia's development wouldn't have been so fast.

However, Li Qingyun is an unsung hero, and no one knows his exploits.

Of course, Li Qingyun didn't care. Anyway, for Li Qingyun, the initial star is just an ordinary planet in his small world.

Even Hua-Xia has dug up all the resources on it. For Li Qingyun, there is not much loss.

But can they hollow out the planet?

Obviously, it is impossible.

On the earth, so many countries, so many machines, and so many years of digging, they have not hollowed out the earth.

If Hua-Xia wants to hollow out the initial star, it is simply impossible.

Besides, as long as Li Qingyun wants to, he only needs to spend some energy to make those resources that were dug up grow again.

After all, that chaotic aura can evolve all things, but ordinary people don't use it.

Of course, Li Qingyun himself will not use it. But it doesn't matter if he doesn't, the Heavenly Dao will be fine.

When Li Qingyun returned to the Martial Arts Continent, it was already very late. However, when he returned home, he found that no one in the family had slept yet, and it was obvious that they were all waiting for Li Qingyun.

Although they all know that with Li Qingyun's strength. No one could help him. Still, they are worried.

After seeing Li Qingyun come back, they went back to their rooms to rest.

Li Qingyun was also very moved by this. But a lot of words flashed through his mind, but he couldn't say it.

Back in the room, Li Qingyun hugged Niuniu and told her everything she saw outside today.

Niuniu listened very quietly and didn't interrupt, she was completely listening to the story.

When she heard that many people now wanted to enter the Martial Arts Continent and wanted to let the Martial Arts Continent take action to treat their diseases, Niuniu couldn't help laughing.

Yes, she's laughing at the naivety of those foreigners, who they think they are. They thought that after a parade, Li Qingyun would give in.

Yi Niuniu's understanding of Li Qingyun. He is not a nationalist, for those foreigners, in Li Qingyun's eyes, they are a group of barbarians, who don't even eat fully cooked meat, even eat raw vegetables, and the ancestors of Hua-Xia didn't eat raw thousands of years ago.

Moreover, the ancestors of those foreigners, but when Huaxia was weak, they invaded Huaxia together, and this hatred may be forgotten by many Huaxia people. There are even many Hua-Xia people who think that the moon in foreign countries is rounder than Hua-Xia, and that everything in foreign countries is good.

They want to immigrate in every possible way, and they want to get the so-called green card.

Li Qingyun looked down on those people very much.

That's right, as Li Qingyun's pillow person, Niu Niu, knows Li Qingyun very well, he is a nationalist who cuts his head and tail.

To put it mildly, Li Qingyun doesn't care if those foreigners live or die.

Don't say they're just marching in protest. Even if they ran to Li Qingyun and killed themselves, Li Qingyun would only watch it as a show, and would not stop it.

This is the real Li Qingyun.

Niuniu was not interested in those who marched, but she was very interested in Li Qingyun being able to teleport in the earth's space.

In the past, when they went out, they all asked Li Qiankun to take them. Although Li Qiankun is nothing more than a puppet man. But Niuniu always felt that it was not the same thing for him to be by his side.

If Li Qingyun could teleport by himself, then Li Qiankun would not be needed, so wouldn't it be more convenient for them to think of where. And I'm not afraid of being disturbed.

Therefore, Niuniu asked Li Qingyun to take her out to play the next day.

In this regard, Li Qingyun of course agreed in one bite.

Anyone, with a new ability, wants to find someone to show off, otherwise, what's the point of stealing fun by yourself. Although Li Qingyun is a master of the Transformation Period, he is still alone. He also wants to be worshipped.

Especially letting his wife worship him, this will make Li Qingyun feel a sense of accomplishment.

The two of them are here discussing going out secretly tomorrow. And he didn't bring Li Qingjing's light bulb.

Li Qingjing didn't know what her brother and sister-in-law discussed. Otherwise, she wouldn't have done it.

Anyway, it's not once or twice that she makes light bulbs, she's used to it for a long time.

The next day, early in the morning, before Li Qingjing got up, Li Qingyun left the house with Niuniu.

As for Xixi and Hanghang, they are naturally taken care of, and it can be said that Li Qingyun, who is a parent, can be said to be the most worry-free parents in the world.

From the birth of two little ones to the present. Although it has only been a few months, they have never been worried about it in the past few months.

Other people, who have just become parents, should not think about sleeping well at night, because the little one will not be able to sleep at all in the middle of the night.

But Xixi and Hanghang have never done anything like this. When they grew up, they didn't even sleep in the same room with Li Qingyun and them. Even during the day, Li Qingyun wanted to play with them, but they didn't want to.

They can run, but they can't be still.

Therefore, Li Qingyun and the others left at this time, and it had no impact at all.

Ordinary babies, when they are their age, are still breastfeeding. However, Xixi and Hanghang were already more than two months old, and when their teeth first erupted, they refused to drink milk. Not even with a bottle.

Because they feel that they are all big children and should eat. Drinking milk will be laughed at by others. Although no one ever laughed at them. But they didn't want to drink it, and Li Qingyun and they had no choice.

As for Niuniu, she won't say anything, so it saves her a lot of things.

Therefore, they walked very freely. When Li Qingjing got up, she found that her brother and sister-in-law had disappeared, but she was angry.

After all, in the family, there are only brothers and sisters-in-law among peers. Now that his brother and sister-in-law are not at home, he can't even find someone to talk to.

As for Xixi and Hanghang, they don't have the patience to chat with him.

As for my parents, forget it and tell them that it's just to make myself uncomfortable. When the time comes, they have to urge her to find a boyfriend, and when they think about it, it gives her a headache.

No matter how Li Qingjing kept cursing Li Qingyun at home, Li Qingyun had already taken Niuniu to play all over the world at this time.

As for him daring to teleport around with Niuniu, it is not as bold as Li Qingyun. Yesterday, Li Qingyun did an experiment.

As for the subject of the experiment, it was he who casually knocked out a gringo, and then took him with him, leaving dozens of their footprints around the world in a matter of minutes. In the end, Li Qingyun sent him back to where he was.

When he came to his senses, of course, he must not have remembered that he had made a global trip in just a few minutes.

When he woke up, he saw that the snowflakes on his body were still very depressed.

I've grown so big, I haven't seen snowflakes yet. Why is it good, there are snowflakes on him. Hell yes, it's not true.

Yes, the person Li Qingyun knocked out was an African. is still a man from the country of mummies, he has never been abroad since he was a child, and he has only seen snow on TV.

And of course he didn't know that he had been in Antarctica for about ten seconds before he woke up. And the snow on his body fell at that time.

Even when he woke up, he found that his body was very cold.
