"Professor, this is the simulated ocean zone."
"With the wave-generation system, we can simulate waves and tides in real time."
At those words, Lü Yongchang turned to look in the direction Shen Siwen was pointing.
A pool, neither particularly large nor particularly small.
This was the so-called "ocean."
He crouched down and examined it carefully. "The water quality looks good."
Shen Siwen shook his head with a bitter smile. "Professor, this is the result of our second experiment."
"Hm?" Lü Yongchang raised an eyebrow slightly. "What do you mean? The first experiment failed?"
"Ah." Shen Siwen sighed softly. "During the first experiment, we ran into the same problems as the United States."
"Red tides spread throughout the simulated ocean, and large numbers of the organisms we introduced died..."
"Things only began to improve after Zero took over the main control system."
Lü Yongchang said nothing, merely directing an inquisitive look at Professor Shen Siwen.
"Professor Lü, although Biosphere Two has achieved some initial success, I have to throw cold water on your hopes." After a moment of silence, Shen Siwen continued, "With humanity's current technology, building a self-sustaining biosphere aboard a starship is essentially impossible."
Lü Yongchang's expression shifted slightly.
How could this be?!
According to the system, artificial biosphere technology was clearly a prerequisite for starship manufacturing!
Could the system contain incorrect information?!
At that thought, Lü Yongchang's expression instantly darkened.
"Professor Shen, sorry for the trouble, but could you explain in detail?"
Shen Siwen sighed softly. "With Zero's help, we ran countless simulations."
"In the end, we found a combination that could just barely maintain equilibrium."
"Even then, this biosphere still needs Zero to monitor it in real time and make all kinds of fine adjustments."
"For example, if the carbon dioxide concentration in the biosphere gets too
