Cataclysmic Era: I can unlock the tech tree

Seeing Lu Siyuan's excited expression, Mao Zhengzhi's smile grew even wider.

"What's wrong?"

"Is this the successor you're grooming?"

Mao Zhengzhi turned his head to look in the direction from which the sound came, and saw Lü Yongchang walking towards him with a smile in his eyes.

"Professor," he greeted first, then hesitated for a moment before replying firmly, "I think he's a good choice."

"At least in the field of biology, he is a talent worth developing."

"Oh?" Lü Yongchang looked at Lu Siyuan, who was busy at the control panel, with some surprise. "This is the first time I've heard you speak so highly of someone!"

As his gaze fell upon Lu Siyuan, a holographic projection appeared beside him.

The projection clearly displays Lu Siyuan's resume information from birth to the present.

With just a quick glance, Lü Yongchang's eyes showed a hint of surprise: "The new generation of Gliese?"

"Yes." Mao Zhengzhi nodded with a smile. "Speaking of which, he is a new kind of human being born from the social welfare system."

"Moreover, he was among the first group of new humans to work at the Academy of Sciences."

Looking at the densely packed resume, Lü Yongchang was even more astonished. "That resume is quite impressive!"

"They've mastered cutting-edge biological knowledge in such a short time!"

"It seems the social welfare system is doing a pretty good job with education!"

"It's not entirely thanks to education," Mao Zhengzhi said with a smile, correcting Lü Yongchang's words.

"Continuous optimization at the genetic level has significantly improved the average physical fitness and average intelligence of people."

"Human evolution, which has progressed slowly, seems to be accelerating under the stimulus of the public system!"

"Moreover, with Zero's control, the teaching materials are also updated in real time to keep pace with the intellectual development of the new generation."

This creates a positive cycle.

After a moment's thought, Mao Zhengzhi spoke again.

"To put it another way... the theoretical system of the Earth era is now the basic textbook for the new humans to enter school."

Lü Yongchang nodded thoughtfully.

"What about humans who reproduce naturally?"

"Natural reproduction?" Mao Zhengzhi chuckled. "Professor, you probably haven't been paying much attention to the news from the Sociology Department."

"When the social welfare system was first implemented, many new individuals were born each year."

"But as time went on, the public care system matured, and people gradually discovered the advantages of the new generation."

"Extremely high intelligence, coupled with zero targeted instruction..."

"No matter what industry they are in, they are extremely competitive."

"Fortunately, the number of new humans born each year is precisely controlled, so this situation has not had a major impact on society."

"However..." Mao Zhengzhi shrugged, somewhat helplessly, "Just like natural selection, natural humans are gradually being eliminated by the new humans."

"When we left the Gliese 555 system, the annual number of natural human births had already fallen to an all-time low."

"With persistent promotion, people's attitudes have changed considerably."

"Whether for the sake of the next generation or for other reasons, almost all couples choose to apply for public care quotas."

"According to the predictive model analysis of the sociology department at that time, under normal development, in about two hundred years, the social support system could completely replace the original reproductive system."

After listening to Mao Zhengzhi's "report," Lü Yongchang breathed a long sigh of relief, and his tense body relaxed a bit.

A huge weight was finally lifted from his shoulders.

With the help of various data provided by the Proxima Centauri civilization, the reform of the human fleet was finally successfully completed.

only……

"Has the implementation of the public-funded system been free of any drawbacks?"

Lu Yongchang's question brought a bitter smile to Mao Zhengzhi's face.

"Drawbacks?"

"Of course."

"The original family values ​​were greatly impacted."

"Of course, under the regulation of the sociology department, everything was under control, and the original concept of a small family was slowly developing into a concept of a large family, as originally expected."

Mao Zhengzhi's words were not beyond Lü Yongchang's expectations.

The concept of a small family is a traditional idea that humans in the Earth era maintained their relationships through blood ties.

The concept of a large family is a new idea proposed by the Chinese Academy of Social Sciences for the purpose of establishing a public welfare system.

With the gradual advancement of public care systems and education, the focus of the new generation is no longer limited to small families bound by blood ties.

In a broad sense, all human beings belong to one big family.

Therefore, the new humans primarily focus their attention on human civilization as a whole.

The development of civilization is paramount.

It sounds simple, but even now, this idea is only just beginning to sprout among the new human population.

To truly solidify this concept, it will likely require an extremely long period of effort from the education system.

In a sense, the day this concept is fully established will be the day the social welfare system truly succeeds.

Thinking of this, Lü Yongchang let out a long breath.

From the moment the first public-born humans were born, humanity could no longer be called humanity.

Just like a fish that has come ashore, it can no longer be called a fish.

But this was ultimately a last resort.

The price paid by the human fleet to survive in this dark and cold universe should be considered relatively low.

Thinking of this, a hint of helplessness appeared in Lü Yongchang's eyes, and he sighed softly, "It's a pity that once the public care system was established, humanity can never go back."

Mao Zhengzhi's expression shifted slightly.

He was certainly aware of the meaning behind Lü Yongchang's words.

He was silent for a moment, then responded in an extremely deep voice.

"Professor, perhaps, from the day humans left Earth, humans should no longer be called humans."

Lü Yongchang's expression changed slightly.

He stared intently at Mao Zhengzhi beside him, and after a long silence, he sighed silently.

"That's right..."

"After leaving Earth, humanity has changed so much that it can no longer be called human."
