"Yes, there is a large amount of helium-3 energy on the moon. These are high-quality fuels for controlled nuclear fusion. Calculated, it is indeed enough for ten billion people to use for tens of thousands of years." Lin Shi said.

As for the world tens of thousands of years later, by that time, human beings should already have more powerful technology, and even be able to directly extract dark energy from the vacuum.

No matter how much Xu You shoulders the mission of all human beings, he will not think about the human beings tens of thousands of years from now.

And by that time, whether human beings will still survive in the universe is still unknown.

After introducing the indoor light and air circulation system, the staff continued:

"The purpose of the underground shelter is that people can meet all the daily needs of human beings without leaving the room for a long time. For example, if we want to eat a certain kind of food, we can place an order directly on the platform."

With that said, the staff opened a certain virtual software platform on the mobile phone, and after some operations, the order was completed.

Just a few minutes later, the platform displayed the message "Order delivered".

"Look, this is the location in the room that is specially used to receive various takeaways and express delivery."

As he said that, the staff opened a camera obscura hidden in the living room, and sure enough, the food that the staff had just ordered on the online platform appeared inside.

Seeing such a scene, everyone was shocked again.

"I thought I needed to open the door to pick it up. I didn't expect that I could receive takeaways and express delivery so quickly without leaving home." Lin Shi sighed.

"Yes, it is the kind that does not even need to open the door in the true sense. In the underground shelter, we have established a complete logistics channel that can automatically initiate delivery from the nearest warehouse. Users can receive the goods ordered on the platform in minutes. Even for a real underground shelter on the moon, the delivery time can be controlled within an hour."

When all the humans on Blue Star really live underground on the moon, various economic activities will continue, and logistics will be a very important part.

Because of the advanced logistics system and the perfect algorithm, it is even more convenient than the current Blue Star.

Listening to the staff's introduction, Lu Zhiyao couldn't help but sigh:

"Why do I feel that I am already looking forward to this kind of life? Is it because I have been staying at home for too long, if I can live so comfortably without going out, then I really don't want to go out. "

"Haha, Mrs. Yaoyao, after hearing what you said, I also think this kind of life is not bad. But it is precisely because of the setting of underground shelters that the logistics system can be so developed." Lin Shi said .

Listening to their conversation, Xu You said with a smile:

"Actually, if you really want to, Blue Star can also realize this kind of logistics. However, this requires the construction of a complete logistics system underground, and the amount of engineering is still relatively huge. After all, Blue Star will definitely not be able to reach the underground refuge of the moon. The population density of shelters cannot be compared with shelters.”

At this time, the staff opened the food that had just been received.

It was a freshly prepared takeaway, and because it was carefully packaged and delivered quickly, the food inside was still warm.

"This is...steak?" Lin Shi asked in surprise.

"Yes, not only steak, but also artificial beef using the latest technology. This is not the kind of artificial beef that uses plant protein, but beef made with animal cell base. There is not much difference from real beef, even the taste Even better."

Xu You knew a long time ago that there will be such a session today, just to taste the taste of this artificial meat.

"Is this... safe?" Lin Shi asked.

Lin Shi did not participate in the project of cell-based artificial meat. She didn't know what the whole research process was like, and she still had doubts about food safety.

At this time, Xu You took the lead to pick up a steak, and said to Lin Shi:

"Don't worry, I participated in this project, and the safety issue is completely guaranteed. It is said that Professor Gao and the others have eaten a lot of this kind of cell-based artificial meat during the experiment, and there will never be any safety issues. "

While talking, Xu You picked up a small piece of steak and tasted it.

"Well, the meat is very tender and the juice is very rich. The overall taste is very fresh and tender, and I think it is tastier than normal beef."

Xu You truthfully expressed his inner thoughts. Seeing Xu You enjoying himself, everyone also picked up their share of steak and began to taste it.

"Hmm! The teacher really didn't lie, it's really delicious!"

"If you don't specify it, you can't tell that it's man-made beef. I'm just worried that ordinary people will not accept this kind of food psychologically if they know it's man-made beef."

After tasting it, everyone praised this new type of cell-based artificial meat without exception.

Afterwards, the staff continued to introduce the various advanced supporting facilities in the room.

There is not only a complete water and sewage system in the room, but also a garbage disposal system that is not available on the market, so you don’t even need to go out to throw garbage.

Everyone feels that this kind of underground shelter is undoubtedly very friendly to those who usually like to stay at home.

Just then, the doorbell rang outside.

The staff opened the door and found that the person outside was Luo Wenkun.

Luo Wenkun was going to experience the underground shelter with Xu You and the others today, but due to work reasons, some time was delayed.

After finishing the work at hand, Luo Wenkun rushed over immediately, and finally did not miss the meeting with everyone.

"Sorry, I have something to do, I'm a little late." Luo Wenkun said with a smile.

"No, Wenkun, you came just in time. There is also a steak here. Try it while it's hot."

With that said, Xu You handed the last piece of steak to Luo Wenkun.

Luo Wenkun didn't question the safety of the steak like Lin Shi did. He directly took the steak that Xu You handed over and began to taste it.

"Well, the taste is really good. This is the latest cell-based artificial meat technology researched by Professor Gao Mi's team. I didn't expect the technology to be so mature that it can be put on the market directly."

"Yes, at least in terms of taste and safety. Of course, the production efficiency can continue to be improved."

After tasting the artificial beef, Luo Wenkun said:

"By the way, I just made a decision that I will live in an underground shelter for a while,"
