"Is this a golden asteroid?"

Yun Yi looked at the planet he encountered on the road outside the spacecraft, and the asteroid was not small in size and emitted golden light in the sunlight.

"What's strange about it? Gold and silver are just precious on Earth. This is just an ordinary mineral in the universe. In the future, you will see a planet consisting of greater purity and higher-quality planets. "

Yun Yi shrugged and admitted his ignorance. However, after just passing by the golden asteroid, another asteroid reflected a dazzling light appeared in front of him: "Isn't this the entire asteroid a diamond?"

Chu Ji did not answer Yun Yi's words, and imitated Yun Yi to shrugg and make a promise. It seems that the barren starry sky is not barren for humans who have never seen the world. On the contrary, the material they possess will exceed human imagination.

God knows how big and heavy the diamond asteroid I just passed by?

Observing the asteroid belt from the earth seems to be very dense here, but when you go deeper, you will find that each asteroid is actually very far apart. Some people will not find them until they get closer. For example, it seems that a not-so-large asteroid suddenly appears in the foreground.

"It is the real beauty. Does it feel like looking at the stars in the universe?"

Yun Yi was already stunned. It was indeed beautiful, as if the starry sky was slightly indented into this asteroid, and countless stars were flashing.

"Star steel is not available on the earth, but the asteroid belt has abundant reserves. The origin of its name is because its appearance is the same level of material as dark gold. We are lucky in this remote corner because there are many metal minerals lacking in other civilizations, which will at least not affect the technological development of our civilization."

It took Yun Yi a long time to come to his senses. The intelligent life of Xingchengang for the first time may have the same reaction. The surface of Xingchengang will involuntarily attract their attention and will be deeply addicted to it.

"You said that the star steel solar system is not short of it, right?"

"Yes, it's more than dark gold. There is a huge mine on Titan. It used to be one of the main export resources of the Tiansheng Empire."

"There are all extra exports. It seems that we are indeed not short of Xingchen Steel. This is another great benefit! Do we have the materials to produce third-level civilized space warships?"

"So I said that Emperor is lucky. Most of the solar system exists, and only a few of them do not exist in the surrounding galaxies. For example, the blue core mine necessary for our energy shield must go to the Brandt 2147 galaxy, and the nearest mine to us is there."

"Brand 2147 galaxy is only 8.2 light years away from us, and it doesn't take much time. It seems that this universe treats us fairly."

Chu Ji did not respond to Yun Yi's words, but muttered in her heart: "Now, you will not feel that way in the future. Compared with the richness of resources near the Milky Way Galaxy, there is no precious material in this remote small corner. It will definitely seriously hinder the progress of the empire's civilization. Although the empire's black technology system can transform basic minerals, it must be much more expensive than the material they originally had."

Chu Ji did not say this, so that Yun Yi would be so happy there. By then, he would naturally understand this cruel reality when he reached a certain level.

The spacecraft flexibly traveled through the asteroid belt. Yun Yi saw countless mineral planets. The common minerals on Earth are ordinary things, and the reserves are beyond human imagination.

Although the current gold in the imperial system is still a major resource, Yun Yi has seen too many gold deposits in the asteroid belt, including asteroids composed simply of gold, and also a mineral deposit mixed with copper and gold. I believe that after collecting them, the resource items of the imperial system will be burst.

"Don't think of good things. After the empire is promoted to a first-level civilization, the interface of the empire system will also change accordingly. All current mineral resources will be converted into basic materials, and the quantity will be extremely compressed, and the original system unit of measurement will also change."

Zero appeared at the right time and poured cold water on Yun Yi.

Without zero reminding Yun Yi, he also imagined that the empire system would change. He was just fantasizing about beautiful things, but his intelligent life was very qualified and did not give him this opportunity.

The flight of the spacecraft seems to be a treasure hunt. Although most asteroids are only rocks and ice as the main ingredients and are of no use, unexpected discoveries are always surprising.

Many mineral deposits that Yun Yi had never seen before were known in Chu Ji's introduction. Although he didn't know what the finished product looked like, at least Yun Yi had a preliminary understanding and use of them.

For example, Misilan used to produce energy conversion devices, Dai Pei has not been successful because she does not have this mineral. Her success is because she has purified silver ore without restrictions to barely meet the requirements for use. There is no need to be such a troublesome use of Misilan. It can easily and stably derive the energy in the energy stone for human use. Moreover, this mineral is like iron ore, gold, and copper ore in the cosmic starry sky. Unfortunately, the earth does not have it.

"Chu Ji, is Mars worth transforming? Asteroids made up of too many ice cubes?" Seeing a huge ice cube again, Yun Yi suddenly thought of Mars.

"It can be transformed, but the cost is too high. Let's talk about it when the civilization level is higher. At least level four civilization is needed."

"You can make preparations in advance. Pull these asteroids made of ice into the Mars orbit and throw them into Mars will always have some value. Isn't it said that with fresh water, there will be life? And it's not far from Mars."

Chu Ji rolled her eyes and said, "We have spent a huge price on high-level civilizations. Is it worth it? Anyway, we do not lack life stars in the surrounding star fields, and our main task now is to develop fleets and establish defense systems within the solar system. Do you think the entire solar system will have no defense measures in the future, and let people from other civilizations enter and exit at will?"

"How to defend? How big a line of defense should be built?"

Yun Yi was a little stunned. He had never seen how the interstellar civilization defended its base camp. But if he didn't understand, he would ask. Chu Ji wouldn't despise him too much, right?
