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

After a long time, he hesitated and said, "Professor, if we just build a Martian city for human habitation, maybe our algorithm can do it."

"However, it will likely require significant input of resources to keep it running."

Lu Yongchang's eyes lit up suddenly when he heard this.

Enter a lot of resources?

This is nothing at all!

The technology for industrially synthesizing proteins and carbohydrates has been perfected. Even without crops and livestock, human beings can survive under a complete industrial system.

However, the quality of life will be slightly reduced.

Thinking of this, a faint smile appeared on the corner of Lu Yongchang's mouth.

He stretched out his hand and patted Shen Siwen's shoulder hard in front of him.

"Professor Shen, I leave this task to you!"

Shen Siwen: "???"

As if afraid that Shen Siwen might misunderstand the meaning, Lu Yongchang explained again in detail: "I need you to design a Mars city that can accommodate 5 million people, resource consumption is not a problem, the key is to ensure the stability of the internal environment! "

"I will arrange other researchers to assist you. Within three months, I will see the complete design plan."

"In six months, humans will be completely evacuated from the earth. We need to allow some time for the construction of Mars City."

Chapter 172 Escape "Eve"

Facing Lu Yongchang's request, the corners of Shen Siwen's eyes twitched again.

A city of Mars where 5 million people live together...

This is not an easy job!

Not to mention anything else, just talk about the Mars module in the former United States.

Accommodating only three astronauts and staying on Mars for less than a month, serious problems occurred.

According to Lu Yongchang, [-] million people will live in Mars City for several years.

Even with the input of external materials, the difficulty of this project is still extremely high in order to stabilize a Martian city that can accommodate [-] million people.

But... the task has already come down, can he still refuse?

Shen Siwen sighed silently, subconsciously stretched out his hand to touch the little hair on the top of his head, and said in a low voice, "Professor, I will try my best."

"It's just... there is one more thing I need to apply to you."

"Tell me." Lu Yongchang responded directly without any hesitation.

"Professor, I think it is necessary for us to start the gene preservation plan." Shen Siwen said seriously.

"Not just edible livestock, but many essential animal and plant genes, and even quite a few microbial populations."

"These creatures play a vital role in our future immigration and planet transformation plans!"

Lu Yongchang nodded thoughtfully.

Makes sense.

Humans can enter the hibernation cabin to start interstellar voyages. These animals and plants can't arrange several hibernation cabins, right?

The transportation of living bodies consumes a lot of money and is extremely risky.

Therefore, transporting genes has become the best choice.

It is only necessary to ensure that there are sufficient genetic samples. After the technological level reaches the standard, they can completely rebuild a "earth" after arriving on a habitable planet.

"Okay." Lu Yongchang said in a deep voice, "Give me a biological list in the next few days, and I will arrange someone to take care of it."

……

2033.1

Months flew by.

Under Zero's control, [Tower of Babel] and [Building Wood] have already been completed.

The perspective moves to a distance of 9.1 kilometers from the surface.

At this time, the earth has no longer recovered its original blue appearance.

The entire surface of the planet is covered by dense white clouds.

This is because the internal reaction of the sun is becoming more and more intense, the temperature of the earth's surface is rising, and the seawater is evaporating in large quantities.

And in this thick white cloud layer like cotton candy, two slender ribbons pierced impressively!

The ribbon stretches for a full 9.1 kilometers and is connected to two huge silver-white discs in space.

This is the last technological crystallization of mankind in the past year.

space port.

Each spaceport is 10 kilometers in diameter and has 4 "ports".

And around these ports, 800-meter-long starships parked quietly in the empty space.

They are Luanniao I starships that undertake the human escape plan.

Dozens of helium trifusion reactors provide sufficient energy for it, and driven by the latest Hall thrusters, the Luanniao I starship can reach a speed of up to 200km/s.

……

Qinghai-Tibet Plateau.

Although the global average temperature continued to rise during the past six months, the glaciers at the two poles basically melted away.

However, as the roof of the world, the Qinghai-Tibet High is due to its terrain. Not only is it not eroded by sea water, but the temperature is even much lower than that in low-altitude areas.

But even so, at this moment, the temperature on the Qinghai-Tibet Plateau in winter has reached about 10 degrees Celsius.

This is about [-] degrees Celsius higher than the normal temperature in the past!

Coupled with the increasing precipitation, the Qinghai-Tibet Plateau at this time looks like a water town in the south of the Yangtze River.

Lush pastures and bushes are everywhere.

The only pity is that the animals and plants that were originally unique to the plateau quickly disappeared because of the rapidly changing environment.

The space elevator [Jianmu] is located in a high-altitude area on the Qinghai-Tibet Plateau.

Because of the fragile geology of the Qinghai-Tibet Plateau, it took a lot of work to lay the foundation.

A group of newly built buildings is quietly located near the foundation of the space elevator.

Due to the gradual deterioration of the environment, the People's Federation's first laboratory had to be relocated to the Qinghai-Tibet Plateau area.

At this moment, there are only a few million conscious people left on the entire earth. In order to save resources, excluding the 38 billion people who escaped, the remaining [-] million people on the earth have also entered the hibernation cabin.

Only when Lu Yongchang and the others leave the earth and arrive at Mars, will these [-] million people be awakened again.

Among these [-] million people, apart from scientific researchers, most of them are starship pilots and various workers.

At that time, they will not only be responsible for promoting the progress of basic science, but also obtain the resources needed for interstellar navigation in the entire solar system as much as possible!

……

Lu Yongchang stood by the office window, silently looking at the scenery outside the window.

Eyes full of life.

There was emotion in his eyes.

It has to be said that the miracle of life appears all the time.

Even though the earth has reached such a state, there are still several "Xanadu" in the world.

"Hey……"

Thinking of the humans who were about to be forced to leave the embrace of their home planet, he sighed slightly, and asked in a low voice: "Zero, the start of the escape plan is today, right?"

The holographic projection quietly unfolded.

"Yes, Professor." Zero responded calmly, "Currently, the last batch of hibernating humans in the escape plan are going to the spaceport via the space elevator."

"It is estimated that in one hour, the last Luanniao-[-] starship will sail out of the space port."

"Professor, do you need to play live video?"

Lu Yongchang's eyes moved slightly, and he turned to look at the holographic image behind him.

"it is good!"

The screen changes rapidly.

[Jianmu] In the space port, the whole body is silver-white, and the hibernation chamber filled with light yellow deep-sea fluid enters the 800-meter-long Luanniao I starship along the track continuously.

In the upper right corner of the screen, a bright red number is beating quietly.

That's the time it takes for the last starship to fill the hibernation chamber, and it's also the time for these 38 billion people to set off for the Kuiper belt!

"Professor, the chairman of the council is here."

As Zero's voice fell, the office door quietly opened.

Looking at the old man with a cane at the door, Lu Yongchang hurried up to meet him.

"Chairman, why are you here?" Lu Yongchang showed a bit of annoyance in his eyes, "If you want to find me, just call Zero directly."

The old man walked into the office slowly while leaning on crutches, while smiling cheerfully and waving his hands.

"No problem, no problem."

"Unlike you, after everyone hibernates, I have a lot of free time now."

Speaking of this, the old man said with a slightly exaggerated expression: "You don't know, recently I don't see a few new documents on my desk every day."

Hearing this, Lu Yongchang suddenly laughed.

"Would you like to be free?" He winked at Su Yutong and said, "You have been tired for such a long time, can't you take a rest?"

Su Yutong at the side silently moved a chair and placed it beside the old man.

The old man smiled and nodded towards Su Yutong: "Thank you."

"I don't want to rest!" The old man's eyes were full of emotion, "If the earth can still be the same as before, I will be fine even if I am busy day and night."

Hearing this, the atmosphere in the office fell silent again.

The old man was keenly aware of this, and in order to adjust the atmosphere, he moved his eyes slightly and said jokingly.

"Speaking of which, Yutong, how is your relationship with Yongchang now?"

The moment Su Yutong heard this, shyness flashed in his eyes, and he pretended to be calm and said: "Chairman, I am only Professor Lu's assistant."

Lu Yongchang also looked at the old man with a wry smile on his face: "Chairman, what time is this, are you still in the mood to joke?"

Looking at the two young men in front of him, the old man sat on the chair and laughed.

"Okay, okay, my old bones will not get involved in your young people's affairs."

PS. Dear readers, Kavinka is amazing today, and it took me a long time to grind out this chapter, so... there is only one chapter today, and I will add another chapter when the status is adjusted tomorrow.

I need to change the map next, I have to go through the plot QAQ

Chapter 173 380 Spots of Light

Facing the ridicule of the old man, Lu Yongchang could only look helplessly at Su Yutong beside him.

During this period of time, although he was aware of the thoughts of Su Yutong and the chairman of the council, but the crisis was hanging over his head, and he really didn't have extra thoughts to think about these trivial matters.

"I heard that Yutong's current scientific research level is already very good?" The old man closed his eyes slightly and asked casually.

Lv Yongchang was stunned for a moment, and hurriedly nodded in response: "Over the past year or so, the progress has indeed been great."

"However, compared with the older generation of researchers, she still has a big gap."

The old man opened his eyes again, glanced at Su Yutong with relief, nodded slowly and said: "Not bad, not bad..."

"We're getting old."

"After leaving the solar system, you are the future of the People's Federation."

"Work hard and try to drive this kid Lu Yongchang over."

Speaking of this, the old man couldn't help chuckling.
