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

But for this situation, he has nothing to do.

At present, the manufacturing projects of Spaceport, Luanniao Project and [Jianmu] have completely squeezed out Zero's computing power.

If the computing power is allocated to build shelters, which slows down the progress of other projects, the consequences will only be more serious!

"What's the other good news?"

After a moment of silence, Lu Yongchang took a deep breath, cheered up a little, and asked Fang Xu.

Hearing the question, Fang Xu shook his head and pulled himself out of the heavy atmosphere just now.

"I'm sure, you will never guess what good news it is!" Recalling the report he just received, Fang Xu's eyes showed a little joy.

Seeing the doubt in Lu Yongchang's eyes, he cleared his throat and prepared to report.

The holographic projection screen quietly changed: "Professor, the Biosphere [-] experiment has achieved a phased success."

Fang Xu's face froze suddenly: "..."

"Zero, without such..."

As for Lu Yongchang, he naturally ignored Fang Xu's "protest", stood up excitedly, and looked at the holographic image in front of him.

"Zero, arrange a Xuannv No. [-] for me, I'm going to the Ecosphere No. [-]!"

……

Taklimakan Desert.

After the speed of the sun changes, the desert has become a real forbidden zone for life.

In the Taklamakan Desert under the scorching sun, the surface temperature is as high as 90 degrees Celsius.

And in the center of the Taklamakan Desert, a huge hemispherical glass building stands in this restricted area of ​​life, as if provoking the power of nature.

The Xuannv No. [-], which is all black, drew a graceful curve, and landed slowly on the tarmac next to the glass building.

The powerful thrust of the Hall thruster raised countless yellow sands.

Through the porthole, it can be seen that the surrounding of Xuannv No. [-] has become a dim world.

"Professor, here we are."

Zero's voice came: "I have notified Professor Shen Siwen, he is already waiting for you at the door of the isolation cabin."

Lu Yongchang nodded, then looked at the thermometer aside.

The moment he saw the number, he stood up decisively and took out the space suit from the cabinet beside him.

Are you kidding me, with the temperature outside now, I guess he will be able to smell the barbecue in a few minutes after he goes out.

The hatch opened slowly, and Lu Yongchang, who was wearing a silver-white spacesuit, slowly walked out of Xuannv No. [-].

Through the mask, he could clearly see the mummified camels on the sand.

He sighed silently, and walked towards the "hatch door" of Biosphere [-] in the distance.

To ensure airtightness, the Bio[-] project's hatch mimics the spacecraft's design—a circular hatch that a single person can drill through.

He reached out and grabbed the handle of the circular hatch, and twisted it open forcefully.

After several turns, the "hatch door" slowly opened.

He crouched down and got inside.

……

"Professor Lu, hello, hello!"

As soon as he took off his spacesuit and walked out of the isolation cabin, Lu Yongchang heard a shout of excitement.

He raised his head and looked in the direction of the sound.

A little familiar.

"Professor Shen?" He called tentatively.

"Yes, yes, I am Shen Siwen." The visitor walked up to Lu Yongchang cheerfully, holding his right hand firmly with both hands, "Welcome to Biosphere [-]!"

"I also watched yesterday's global speech, your speech was really good!"

Lu Yongchang didn't exchange too many pleasantries, he nodded and said straight to the point: "Okay, time is urgent, I won't talk nonsense anymore."

"Tell me about the current status of Biosphere [-]."

"This is related to the future plans of the People's Federation!"

When Shen Siwen heard this, his expression suddenly became serious!

"Professor Lu, follow me."

With that said, Shen Siwen turned around and walked towards the interior: "The biosphere is different from other research projects. Some things cannot be concluded just by looking at the data. I'd better take you to see it for yourself."

Lu Yongchang nodded, this was also his idea.

Otherwise, he could sit in the office and ask Zero directly about the progress of the project.

After walking a short distance, he keenly noticed the abnormality.

He raised his head to look at the glass dome of Biosphere [-], and saw countless silver-white sequins pasted on it.

"Professor Shen, this is..."

Shen Siwen turned his head, saw Lu Yongchang looking up, and quickly explained.

"It was recently remodeled."

"After the sun changed, the internal refrigeration system couldn't keep up, so we asked Zero to make these reflective sequins to reflect most of the sunlight, leaving only suitable light."

Chapter 171

"Professor, this is the simulated ocean area."

"With the help of the wave-making system, we can simulate ocean wave and tidal phenomena in real time."

Hearing this, Lu Yongchang turned his head and looked in the direction of Shen Siwen's finger.

A small pool.

This is the so-called "ocean".

He squatted down and observed carefully: "The water quality looks good."

Shen Siwen shook his head with a wry smile: "Professor, this is the result of the second experiment."

"Huh?" Lu Yongchang raised his eyebrows slightly, "What do you mean? The first experiment failed?"

"Hey." Shen Siwen sighed softly, "During the first experiment, we also encountered the same situation as the United States."

"Simulate the flooding of ocean red tides, and introduce the death of a large number of organisms..."

"It wasn't until Zero took over the main control system that the situation improved."

Lu Yongchang didn't speak, but turned his questioning gaze to Professor Shen Siwen.

"Professor Lu, although Biosphere [-] has achieved phased success, I have to pour cold water on you." Shen Siwen said again after a moment of silence, "Using the current human technology to create a biosphere on a starship A self-circulating biosphere is basically impossible."

Lu Yongchang's face changed slightly.

How could this be? !

According to the statement in the system, artificial biosphere technology is obviously a prerequisite for starship manufacturing!

Is there wrong information in the system? !

Thinking of this, Lu Yongchang's face turned ugly instantly.

"Professor Shen, please explain in detail."

Shen Siwen sighed softly: "With the help of Zero, we have performed countless simulations."

"Ultimately, we found a mix that was barely balanced."

"Even so, this biosphere requires zero real-time monitoring and all kinds of fine-tuning."

"For example, if the concentration of carbon dioxide in the biosphere is high, zero will require a slight increase in the light intensity of the tropical rainforest area..."

"The current small biosphere is like a chaotic system. You never know what unexpected situation will appear in the next second."

"Only an artificial intelligence like Zero can keep up with its speed of change and adjust it just right."

"Besides... the crops produced by this biosphere are basically only enough for a few of our scientific researchers to eat. Once the number of crops is increased, it will inevitably cause other problems."

"Therefore, it is completely unrealistic for us to realize a truly self-sufficient biosphere within a starship of a few hundred meters or a few thousand meters in size."

Shen Siwen said a lot at once.

Lu Yongchang also understood what Shen Siwen meant.

only……

"Ahem, Professor Shen, I think you have misunderstood what I mean."

Lu Yongchang coughed a few times, and said with some embarrassment: "It's also my fault that I didn't make it clear at the beginning."

"Our current needs are not the kind of ecological starship that is completely self-sufficient."

"The so-called biosphere technology is just to better control the environment inside the starship, do you understand what I mean?"

Looking at Shen Siwen's confused eyes, Lu Yongchang pondered for a moment and continued to explain.

"Make an analogy."

"Although most humans are currently sent into hibernation cabins."

"But in an interstellar voyage, someone needs to be awake."

"In addition to the necessary fleet status monitoring, there are also some basic research that cannot be interrupted."

"At that time, we will build some starships that can accommodate tens of thousands of people to live at the same time."

"Long-term control of the internal environment of this survival starship is the technology we need."

"So, do you understand?"

Shen Siwen suddenly realized!

The corners of his eyes twitched violently.

The ghost knows how much effort he has spent in creating a perfect biosphere during this time!

Among other things, at least half of his hair has fallen out.

"Professor Lu, if your request is only this, then the biosphere project can be declared a success." Shen Siwen said sadly, "If it is just to control the living environment in the starship, as long as there are certain equipment, for the current zero , is not worth mentioning."

After all, after eliminating hundreds of different creatures, even a chaotic system becomes simpler.

"Cough!" Lu Yongchang scratched his head in embarrassment again, and he also found that he did not behave properly.

This is equivalent to asking the chef to cook a table full of Chinese people when he only wants to eat a bite of white rice.

……

After visiting Shen Siwen and the team's research results, Lu Yongchang's eyes moved slightly.

"By the way, if this ecosystem is moved to Mars, can it be maintained?"

Shen Siwen was stunned: "Of course, you only need to build various facilities in equal proportions and introduce the same proportion of biological populations."

"... What if we add another 5 million humans?"

Shen Siwen: "..."

Seeing the shit-eating expression on Shen Siwen's face, Lu Yongchang shook his head regretfully.

"Pity……"

Shen Siwen's expression changed slightly: "Professor, are you planning to bring humans to emigrate to Mars?"

Lu Yongchang nodded: "The surface of the earth will soon be unsuitable for living."

"The original reserves of mineral resources are almost consumed after the escape plan is completed."

"Next, we need to obtain as many resources as possible before the solar helium flash occurs in order to deal with future interstellar voyages."

"Mars is a good springboard."

Shen Siwen frowned, as if thinking about something in his heart.
