Ye Xiaofei had just returned to the desert base when the masters of these forces arrived.

After everyone sat down, Ye Xiaofei asked, "How much of the knowledge I announced, how much did the people below you understand?"

The masters who had a lot to say were stunned for a moment, and a Western master said embarrassedly: "Those technologies whose knowledge far exceeds the earth, if you want to understand them, you have to learn step by step, and you must first understand the previous knowledge before you can further understand the later knowledge, although everyone is working hard, it still needs a process." ”

"Yes, Ye Daoyou, I don't know how you learned it?" asked another old man from the West.

Knowing their thoughts, they just want to get knowledge by passing it on to themselves, Ye Xiaofei said: "I won't hide it from you, the knowledge I got was directly injected into my mind in a special way, and I don't know how it was passed on, what I can do is to take out this knowledge and let everyone learn it by themselves, it is impossible to get knowledge like me." ”

Hearing this, everyone's faces darkened, not to mention, many people have an idea, that is, let Ye Xiaofei announce a method that can be directly injected into the brain domain.

If he didn't want to leave this knowledge on the earth, Ye Xiaofei wouldn't have said much to them at all, and after explaining it, if there were still some plans, Ye Xiaofei would not be polite.

"Ye Daoyou, all the materials you asked us to prepare have been prepared, when will we start building the flying machine?"

Ye Xiaofei looked at everyone: "The reason why I published some knowledge for everyone to learn is to let everyone have the possibility of development, now I will talk about the situation of the aircraft first." ”

At this time, Ye Xiaofei played a graphic on the screen and said: "This is the aircraft we will build, however, if you want to turn this aircraft into reality, there is still a long way to go, first of all, what we need is a way to supply energy, the aircraft flies in the starry sky, and it will definitely not work without power, so there must be a change in the way of energy supply, and we can no longer use the way of energy supply on our earth." ”

"With nuclear energy?" someone asked.

Shaking his head, Ye Xiaofei said: "Although nuclear energy is also a good energy source, the situation in the starry sky is completely different, the places where the aircraft passes after entering the starry sky are completely different, and nuclear energy is not reliable. ”

"No, the study found that there is an inexhaustible supply of deuterium and other elements in the seawater. ”

Ye Xiaofei nodded slightly and said, "You are right, but there are some things you don't know." There are two ways to develop nuclear energy: one is the fission of heavy elements, such as uranium, and the other is the fusion of light elements, such as deuterium, tritium, lithium, etc. This is the energy that we have in our own perception of the world, but the composition of celestial bodies in some places is completely different, and these elements just don't have them, so what about the power source of our aircraft?"

When Ye Xiaofei asked like this, everyone was stunned, this was something they had never seriously thought about.

yes, what if that happens?

I really haven't thought about this situation!

"Doctor Ye, then, what should we do?" Zhu Lingkong asked.

Ye Xiaofei glanced at everyone and said, " This is also what we want to do, what we are going to do is to carry out a subversive change in energy, what we want to do is a new battery, this kind of phone has a kind of energy conversion ability, maybe you will think that it is also somewhat similar to the existing nuclear energy, but what I want to say is that our battery no matter what kind of environment it is in, no matter what kind of element it uses, it can be freely converted, not only that, but also can produce energy that is not weaker than nuclear energy, and safe. ”

Everyone is a little confused about what kind of battery Ye Xiaofei is.

Someone still asked: "Mr. Ye, according to what you said, there should be some complicated devices in the battery, so will the battery be very large?"

"You're right, that is, this battery has a set of various functions in one setting, conversion energy, storage energy, supply energy, these are all indispensable, but our battery volume is not too big, only need the size of the button is enough. ”

"How is that possible!" exclaimed a scholar-like man.

Ye Xiaofei said again: "Of course, don't look at it as just a battery, which also involves space technology, in the world of science and technology, when space technology reaches the extreme, a space the size of a football field can completely use space technology, fold the space, and make the whole space very small." ”

There's another technology out there!

When we heard about space technology, we were even more confused.

Ye Xiaofei put a disc-like item on the table and said: "Let's take a look, this is a folding space, don't look at such a small one, but there is a space the size of several football fields in it, I can fit a lot of things in." ”

A pair of eyes suddenly fell on the folded space in front of Ye Xiaofei.

Ye Xiaofei smiled slightly: "You can come close and watch, you only need to touch it with your internal qi, and you can see the situation in the space." This is a folding space specially made by Ye Xiaofei in order to popularize knowledge, although it is not very good, but it can still shock everyone.

So, one by one, people walked to the disc, and then, according to Ye Xiaofei's words, everyone touched the disc with their internal qi.

It took a while for them to recover.

"I didn't expect anything like this!"

"I didn't even think of it, it's too mysterious!"

"If that's the case, a battery is only the size of a button, and that makes sense!"

"Ye Daoyou, this thing is too useful for us cultivators, if everyone has such a thing, they can carry too many items on their bodies, will this technique also be taught?"

Smiling, Ye Xiaofei said: "As long as I show the technology, I will teach it to everyone, I will announce the technology and space technology of this battery, as for how much your people can learn, it depends on their understanding." ”

"Great!"

Everyone's faces were smiling, and they felt that this thing was really useful to everyone.

"Okay, things have to go step by step, and I will continue to publish some knowledge, you must know that all knowledge is carried out in conjunction with the construction of the aircraft. ”
