After announcing that knowledge to a special place for study, Ye Xiaofei entered the formation and returned to his own territory.

In this place, all forces have their own land, Ye Xiaofei's plate is naturally the largest piece, after he has set up the formation, only he can enter and exit freely, and people from the outside world can't enter even if they want to.

All forces need to send a large number of workers to do things, and the people under Ye Xiaofei who do things are all robots.

Ye Xiaofei doesn't care about how long it takes for those people to figure out the knowledge they give out, for him, building his own flying machine is the key.

Of course, Ye Xiaofei also knows that as long as everyone can thoroughly understand the knowledge they have announced and use it on the earth, the earth's civilization will develop a lot.

"Elf, are we ready with all the materials?"

"Master, there is a problem now, although there are all kinds of materials needed on the earth, but with the current amount of materials on the earth, it is not enough to build our flying machines. ”

"What?" Ye Xiaofei was stunned for a moment, what he was most worried about was the matter of construction materials.

"The planets in the solar system have a lot of materials that we need, and if we do interstellar mining, those materials can still be shipped back. ”

"Mining?"

"Yes, in the case of the craft we are going to build, there are several materials that require a lot of extraterrestrial mining. ”

"Is it possible to mine on the moon?" Ye Xiaofei asked.

"Master, mining on the moon is not recommended. ”

"Why?"

"According to calculations, the moon may be a lighting planet specially refined for the earth by powerful cultivators, and it is also a kind of defensive planet ......"

"What did you say?" Ye Xiaofei interjected when he heard this.

"According to the data obtained from the moon, after calculation, a conclusion can be drawn that the moon should be a planet that protects the earth, and the meteorite attack outside it can carry out some defenses, and at the same time, it is precisely because of the existence of the moon that the earth can have light in the dark, such planets are set up there after careful calculations, if the materials that make up the planet are mined, the whole planet is likely to be unable to protect such a transportation orbit, and will leave the earth. ”

And such a thing!

Ye Xiaofei was really shocked now.

It seems that it is no longer possible to mine on the moon.

"The closest to the earth is Venus, can we mine there?" Ye Xiaofei asked.

The elf said: "Human research on Venus has found that Venus is an extremely harsh planet, the surface is full of volcanoes, lava flows, the surface temperature reaches 470 degrees Celsius, and the temperature in some parts of Mars can reach more than ten to twenty degrees in summer. The composition of Venus's atmosphere is mainly carbon dioxide, which accounts for about 97%, and in the lower atmosphere near the surface of Venus, the proportion is as high as 99%. In the atmosphere 30~40 kilometers above Venus, there is also a layer of dense clouds 25 kilometers thick, which are not composed of water mist, but of highly corrosive concentrated sulfuric acid mist. This concentration of greenhouse gases causes Venus to absorb only the heat of the sun's light, but not dissipate heat, which causes such high temperatures. Huge rains of lightning and sulfuric acid ravaged Venus, as well as hurricanes with speeds of up to 350 kilometers per hour. The atmospheric pressure on the surface of Venus is nearly 90 times higher than that of Earth, and the air pressure on Mars is less than 1% of that of Earth. ”

"This kind of planet is a treasure for cultivators who practice fire-based exercises, and even cultivators who practice wind-based exercises like such a planet, but it is not good for human beings. "Ye Xiaofei is not a person who doesn't know everything, and naturally understands the difficulty of mining Venus.

"The master has also seen the situation of Venus, judging from the situation of Venus, it is indeed impossible to mine, the difficulty is too difficult for the current earth technology, and it is not recommended that the master include Venus in the mining target. ”

"Do you say that there is a cultivator on Venus?" Ye Xiaofei suddenly asked.

"I have made careful observations, and although it is suitable for cultivators to cultivate, I have not seen cultivators. ”

No cultivators?

Ye Xiaofei nodded, and then said, "So, it can only be to Mars?"

"Mars is a good place, and through testing, Mars has all kinds of materials needed by the owner, and it is recommended to be listed as a mining site. ”

I'm going to mine on Mars!

After thinking for a while, Ye Xiaofei asked, "If we want to mine on Mars, what do we need to do?"

"It is recommended that the owner first build a spacecraft to fly to Mars, and after mining through the spacecraft, and then build a starry sky vehicle after obtaining the materials. ”

All right!

Ye Xiaofei sighed, it seemed that the first thing he had to do was to get a vehicle that could fly to Mars.

"You've tested Mars, there shouldn't be any cultivators on it, right?"

"It is true that no cultivators have been found, but there are traces of cultivators fighting on Mars, and from the detection, it is found that Mars was once a battlefield for cultivators. ”

Ye Xiaofei is now more and more curious about the earth, there was a battle of cultivators on Mars, it is impossible for the earth so close to Mars not to be involved, what else has happened, does the earth still have secrets that he doesn't know?

"Examine the deep sea of the Earth and report it to me immediately. "Ye Xiaofei's order to the elves has always been to detect the land, not to explore the deep sea, and now he has a feeling that he still has to study the deep sea, and even study the underground situation.

"Build a flying machine immediately!" Ye Xiaofei gave an order.

As Ye Xiaofei's order was issued, a large number of robots took action.

Recently, after getting a large amount of materials, Ye Xiaofei's robot manufacturing here has become fast, and a large number of robots are produced every day.

Ye Xiaofei also thought about it, anyway, with the technology of folding space, even if there are more robots, he can take them away, after having a large number of robots, as long as there is any problem with the aircraft, he can command the robot to repair it.

Many of the things that Ye Xiaofei wants to do belong to his personal secrets, and these things can only be kept secret by robots, so the manufacture of various robots is of great benefit to his construction work.

After receiving the order, a large amount of material is transported in, and then the various machine tools are deployed, and the same parts are generated.
