Cataclysmic Era: I can unlock the tech tree

"Professor, this is the simulated ocean area."

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

Upon hearing this, Lü Yongchang turned his head to look in the direction Shen Siwen was pointing.

A pool that's neither too big nor too small.

This is what is called the "ocean".

He crouched down and examined the water carefully: "The water quality looks good."

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

"Hmm?" Lü Yongchang raised an eyebrow slightly. "What do you mean? The first experiment failed?"

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

"Simulating a red tide in the ocean, resulting in the mass death of introduced organisms..."

"The situation only improved after zero takeover of the main control system."

Lü Yongchang did not speak, but instead cast an inquiring glance at Professor Shen Siwen.

"Professor Lü, although Biosphere 2 has achieved some initial success, I have to pour cold water on your enthusiasm," Shen Siwen said after a moment of silence. "With current human technology, creating a self-sustaining biosphere on a starship is basically impossible."

Lu Yongchang's expression changed slightly.

How could this happen?!

According to the system, artificial biosphere technology is clearly a prerequisite for starship construction!

Is there an error message in the system?!

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

"Professor Shen, could you please explain in more detail?"

Shen Siwen sighed softly: "With Zero's help, we conducted countless simulations."

"Ultimately, we found a combination that could barely maintain a balance."

Even so, this biosphere still requires real-time monitoring and various fine-tuning.

"For example, if the carbon dioxide concentration in the biosphere is too high, then to zero, we would need to slightly increase the light intensity in the rainforest area..."

"This small biosphere is like a chaotic system; you never know what unexpected situation will occur in the next second."

"Only artificial intelligence like Zero can keep up with its pace of change and make just the right adjustments."

"Moreover... the crops produced in this biosphere are basically only enough for a few of us researchers to eat. If the amount of crops is increased, it will inevitably cause other problems."

"Therefore, it is completely unrealistic for us at present to create a truly self-sufficient biosphere within a starship that is only a few hundred or a few thousand meters in size."

Shen Siwen said a lot at once.

Lü Yongchang also understood Shen Siwen's meaning.

only……

"Ahem, Professor Shen, I think you've misunderstood me a little."

Lu Yongchang coughed lightly a few times and said somewhat awkwardly, "It's also my fault for not explaining things clearly back then."

"What we need right now is not a completely self-sufficient ecological starship."

"So-called biosphere technology is just for better control of the starship's internal environment, do you understand what I mean?"

Seeing Shen Siwen's confused look, Lü Yongchang pondered for a moment before continuing his explanation.

"To give an example."

"Although most humans have been put into hibernation pods."

"But in interstellar travel, there will always be someone who needs to stay awake."

"Besides the necessary fleet status monitoring, some basic research cannot be interrupted."

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

"The technology we need is to achieve long-term control over the internal environment of such a survivable starship."

"Do you understand what I mean?"

Shen Siwen suddenly realized!

His eye twitched a few times.

God knows how much effort he put into creating a perfect biosphere during this time!

Putting everything else aside, at least half of his hair has fallen out.

"If Professor Lü's only requirement is this, then the Biosphere Project can be declared a success," Shen Siwen said with a mournful expression. "If it's just about controlling the living environment inside the starship, with enough equipment, it's nothing to Zero right now."

After all, removing hundreds of different creatures makes even a chaotic system simpler.

"Ahem!" Lu Yongchang scratched his head awkwardly again, realizing that what he had done was not right.

This is like him only wanting a bowl of plain rice, but having the chef prepare a full Manchu Han Imperial Feast.

……

After viewing Shen Siwen and his team's research findings, Lü Yongchang's eyes flickered slightly.

"By the way, if we moved this ecosystem to Mars, could it be maintained?"

Shen Siwen paused for a moment, then said, "Of course, we just need to build all the facilities in proportion and introduce the same proportion of biological populations."

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

Shen Siwen: "..."

Seeing the disgusted look on Shen Siwen's face, Lü Yongchang shook his head with regret.

"What a pity..."

Shen Siwen's expression shifted slightly: "Professor, are you planning to lead humans to Mars?"

Lü Yongchang nodded: "The Earth's surface will soon be uninhabitable."

"The mineral resources we had previously stockpiled were almost completely depleted after we completed our escape plan."

"Mars is a good springboard."

Shen Siwen frowned, as if she was plotting something in her mind.

After a long silence, he spoke hesitantly, "Professor, if it's just about building a Martian city for humans to live in, perhaps our algorithm can do that."

"However, it may require a lot of resources to keep it running."

Upon hearing this, Lü Yongchang's eyes lit up.

Inputting large amounts of resources?

This is nothing at all!

The technology for industrially synthesizing proteins and carbohydrates is already very advanced, and even without crops and livestock, humans can survive in a well-developed industrial system.

However, the quality of life will decrease slightly.

Thinking of this, a faint smile appeared on Lü Yongchang's lips.

He reached out and patted Shen Siwen's shoulder forcefully.

"Professor Shen, this task is entrusted to you!"

Shen Siwen: "???"

Seemingly fearing that Shen Siwen might have misunderstood, Lü Yongchang explained again in detail: "I need you to design a Martian city large enough to accommodate 5 million people. Resource consumption is not a problem; the key is to ensure the stability of the internal environment!"

"I will arrange for other researchers to assist you. I need to see a complete design plan within three months."

"In six months, humanity will completely evacuate Earth, and we need to allow some time for the construction of the Martian city."
