It's reasonable for me to have a two-way foil for a second-level civilization, right?

He had plenty of time to deliver this message to every Marus.

"and many more!"

A heavy shout came from behind: "That... Marus, wait!"

Marus on the 12th stopped and turned around in surprise.

"My lord, you..."

"Put things aside, come in and talk!" the male Proxima Centaur said in a deep voice.

……

"what's your name?"

Facing the question from the male Proxima Centauri, he fell into a brief silence.

"I don't have a name, you can call me number 12."

"Number 12..." The male Proxima Centaur nodded thoughtfully, "Why did you tell us this?"

While asking questions, the male Proxima stared at No. 12 Marus, trying to find signs of lying from his expression.

Obviously, failed.

Marus No. 12 looked very natural, without any panic.

He said in a respectful and natural tone: "Actually, according to our plan, this news will only spread among Marus."

"But... your attitude towards me makes me think that this matter should be told to you."

"I don't know what it feels like, but I haven't felt like this since the moment I was born with memory."

"thank you all."

Aquitas and his father looked at each other.

The male Proxima Centauri sighed deeply: "Are you sure it's true? Is there any evidence?"

There was a bit of bewilderment in his visual organs.

evidence?

He didn't know what proof was, and he didn't know what could be evidence.

When he consciously memorized those conversations, he had surpassed most Maruss.

"I, I can assure you, that's the kind of conversation I'm hearing."

Hearing this, Aquitas glanced at his father beside him with some concern.

The male Proxima Centauri didn't speak, just sat quietly on the chair thinking about something.

Time passed by minute by minute.

After a long time, the male Proxima Centauri opened its breathing hole and forcefully exhaled a mouthful of hot air.

"Number 12, I can tell you clearly."

"If you just break the news to all the Maruss, it won't do anything."

"..." Marus No. 12 looked blankly at the two Proxima Centauri in front of him.

His mind couldn't turn around.

Seeing such a scene, the male Proxima Centauri sighed slightly.

"You didn't come up with this plan, did you?"

Seeing No. 12 affirming his statement, the male Proxima Centauri nodded lightly: "It is already very difficult for you Marus to come up with such a plan."

"You can go back and tell your companions. Next, I will spread this news to all Proxima Centauri."

"Only by combining the strengths of all people can we have a chance."

"You don't even know the power in the hands of those adults..."

As he said that, the eyes of the male Proxima Centauri dimmed.

On the 12th, Maruss nodded with a vague understanding.

He didn't know whether it was right or wrong for things to develop this way.

But since the two Proxima Centauri who had good intentions towards him said so, as a Marus, he could only believe them.

"All right."

"It's almost time, you should go back and hand in the task."

Aquitas on the side said softly.

Hearing this, Marus No. 12 was startled, and quickly looked down at his watch.

The moment he saw the time, a bit of panic appeared in his visual organs.

"Don't worry." The male Proxima Centaur said softly, "Aquitas, you can send No. 12 back."

"Remember, don't send it to the door of the incubation center, try to stay as far away as possible."

Chapter 208 Mining Problems

Mars.

Mars City meeting room.

A gray-haired academician and professor sat around the conference table.

Directly in front of the conference table, a huge holographic image unfolded.

On it, there are several large Chinese characters.

"Space Mining Technology"

Lu Yongchang sat in the first place, his eyes slowly swept across the people in front of him, and there was a flash of emotion in his eyes.

Different from previous projects, this space mining project involves more disciplines, so there are many new faces in the conference room.

"Professor Lu?"

A voice with a strange pronunciation sounded.

Lu Yongchang turned his head and looked in the direction of the sound.

An old man with white hair and typical western features sat on a chair and looked at him quietly.

That was Professor Leonard from the United States.

If he remembers correctly, this Professor Leonard should specialize in space mining projects.

"Professor Leonard?" Lu Yongchang smiled friendly and asked softly, "Do you have anything to say?"

Professor Leonard nodded with a serious expression, picked up the microphone on the side, and coughed lightly.

The originally noisy meeting room fell silent.

All eyes turned to Professor Leonard.

"Professor Lu, according to my previous research, space mining projects are more difficult." Leonard said word by word in not-so-standard Mandarin.

After finishing speaking, he looked at Lu Yongchang with some trepidation.

This is the first time he has cooperated with Professor Lu.

Leonard was a little worried that he would annoy the chief scientist of the People's Federation by saying so.

Lv Yongchang chuckled, nodded and said: "You continue."

Seeing Lu Yongchang's reaction, Leonard's expression immediately relaxed a lot.

"Professor, although we have experience in moon mining, there is a huge difference between the two." Professor Leonard said seriously.

"The three largest asteroids in the asteroid belt between the orbits of Mars and Jupiter exceed 400 kilometers in diameter."

"By comparison, the Moon's diameter reaches 3476 kilometers."

"Everyone, this is the largest asteroid. Most of the other asteroids are within a hundred kilometers in diameter."

"There are even many asteroids with a diameter of only a few hundred meters or a few meters."

"And this creates a more serious problem."

"Its gravitational force is extremely weak, and our mining ship must have a reliable enough fixing method to mine on it." Speaking of this, Leonard shrugged, "Otherwise, when our drill bit is drilling, it will The top of the mining ship flew out."

Lv Yongchang frowned slightly. After a moment of contemplation, he turned to look at Academician Kong Xingbang, who was in charge of developing lunar mining equipment.

"Mr. Kong, this shouldn't be difficult for us now, right?"

Kong Xingbang, with a full head of white hair, frowned and nodded after thinking for a while: "Professor, this technology is not difficult to solve."

"Okay." Leonard spread his hands and said again: "Then, the most important question."

"Professor Lu, what method do you want to use to mine asteroids?"

"Drill mining? Or dynamite mining?"

"With a drill, the mining efficiency is extremely low, and the explosives are difficult to control. Those micrometeoroids in space are no joke."

Hearing this, Lu Yongchang frowned immediately.

Well said.

This is also a problem that has troubled Lu Yongchang for a long time.

There are huge gaps between each asteroid.

For Pallas, Juno and Vesta, the largest asteroids in the three asteroid belts, the difficulty of mining is not very high.

Even now, Xuannv-400 and mining robots are directly dispatched to carry out mining tasks on these three asteroids with a diameter of more than [-] kilometers.

But for smaller asteroids, it is undoubtedly a huge problem to carry out efficient large-scale mining.

Mined by conventional drilling methods, these asteroids are too small for even Xuannv-[-] to stay on their surface.

As for blasting with explosives...it's even more idiotic.

The impact from the explosives is powerful enough to send those tiny rock fragments to extremely high velocities.

At that time, let alone mining, it is estimated that it will be difficult for mining ships to operate in the asteroid belt full of a large number of "hidden weapons".

Thinking of this, Lu Yongchang frowned deeply.

This is not just a disadvantage of explosives mining, even if it is mined by traditional drilling methods, the debris problem is difficult to solve.

50 asteroids are scattered in the area of ​​2.17-3.64 astronomical units from the sun.

It seems like a lot, but in fact, the entire asteroid belt is very empty.

However, once the above two methods are used for mining, countless micrometeoroids will inevitably be formed.

For a starship flying at high speed, a large number of micrometeoroids are like a sharp knife that can kill people!

This is undoubtedly extremely bad news.

"Can't these asteroids be dragged to the orbit of Mars to be mined?" Fang Xu's voice sounded from the side, "If you are lucky, these rock fragments may form a 'Martian ring'."

Lu Yongchang's eyes lit up slightly, but then he shook his head.

"I'm afraid it's hard to do." Lu Yongchang sighed slightly, "The resources consumed by dragging those asteroids are completely out of proportion to the benefits."

"Such a waste."

For a moment, the conference room was full of sighs.

"...Professor Lu, I have a proposal."

A somewhat familiar voice came from the corner of the meeting room.

Lu Yongchang quickly raised his head and looked towards the corner of the conference room.

The moment he saw the speaker, Lu Yongchang couldn't help being stunned.

Tao Yuda?

Lu Yongchang's eyes moved slightly, and the plan of the spherical starship designed by him appeared in his mind.

Perhaps, at this time, an unusual mining method is needed!

Thinking of this, he quickly nodded and looked at Tao Yuda expectantly: "Say it!"
