Cataclysmic Era: I can unlock the tech tree

The moment he saw the image in the holographic projection, a clear sense of disappointment flashed in Lü Yongchang's eyes.

It's so desolate!

Compared to planets like Earth and Proxima Centauri b, this planet in front of us is far too desolate!

Perhaps the only thing worth mentioning is the satellite that accompanies it.

Next to the holographic projection, lines of small text appeared.

Gliese 555 VI

Equatorial diameter: 17347 km

【Mass: 3.5M⊕】(M⊕ is the mass of the Earth)

Rotation period: 24 hours, 59 minutes, and 41 seconds

[Equatorial gravity: 18.614 N/kg]

【…】

Looking at the data before him, Lü Yongchang suppressed his disappointment and began to examine it carefully.

As the data became more complete, the surprise in his eyes grew stronger.

3.5 times the mass of Earth.

Its diameter is 1.3 times that of the Earth.

This scale is already close to the standard of a super-Earth!

only……

That gravity, nearly 1.9 times that of Earth, is not so easy to adapt to.

"Zero, have all awakened personnel immediately proceed to their respective gravity chambers for acclimatization training."

After a moment's hesitation, he added, "Have Mao Zhengzhi come to the command center."

"Received." Zero's voice rang out from the side.

After the order was given, Lü Yongchang once again turned his gaze to the super-Earth before him.

This time, he examined the area even more carefully.

Scattered white clouds floated on its surface, the reddish-brown planet dotted with a few scattered black circular spots.

Using the high-precision optical telescope carried on the detector, Lü Yongchang could clearly see the composition of the black circular spots.

Those are active volcanoes gushing lava!

Looking at the images in the holographic projection, Lü Yongchang's eyes revealed a hint of excitement.

Clouds, volcanoes...

Such a sight means that this planet not only has an atmosphere, but also an active core!

The magnetic field it creates is enough to provide a perfect sanctuary for humankind!

Without any hesitation, Lü Yongchang immediately issued the order: "Zero, conduct spectral analysis of the atmospheric composition."

After a brief wait, brand-new data appeared in the holographic projection in front of me.

Nitrogen: 98.4%

Carbon dioxide: 1.14%

Water: 0.4%

【…】

Lü Yongchang shook his head helplessly.

Unfortunately, there was no oxygen.

The carbon dioxide concentration was also high.

It seems that humans will still be limited to living in enclosed cities.

He turned his attention to the satellite beside him.

It's a supermoon!

The satellite in front of us is much larger than the moon.

[Equatorial diameter: 6186.98KM]

【Weight: 0.13M⊕】

[Equatorial gravity: 5.48 N/kg]

【…】

Looking at the data before him, Lü Yongchang's eyes revealed a hint of emotion.

The information provided by [the artist] was indeed accurate.

This star system is desolate and remote...

But it is indeed the best choice for humanity at present.

Perhaps, in this super-lunar system, human civilization can truly enjoy temporary peace and focus on developing its technology.

Lü Yongchang stared intently at the planet gradually enlarging in the image, lost in thought for a moment.

The plan for these two planets slowly emerged in his mind!

……

"Professor, Academician Mao Zhengzhi has arrived."

Zero's reminder interrupted Lü Yongchang's thoughts.

"Professor, you wanted to see me?"

Mao Zhengzhi walked to the porthole and looked at the holographic projection in front of Lü Yongchang.

When he saw the two desolate planets, he subconsciously frowned: "Is this humanity's future home?"

Clearly, the super-Earth and supermoon did not meet his expectations.

Coming to his senses, Lü Yongchang chuckled and reached out to pull up the continuously improving detection data: "Don't be so disappointed."

"In my opinion, these two planets are just right for humanity today."

"The planet is large enough to easily accommodate all of humanity living on its surface."

"It has a magnetic field and an atmosphere. Its only drawback is that its atmosphere contains no oxygen."

"Resources are not abundant, but they are more than enough to sustain the development of a level three civilization."

"Its remote location and limited resources destined it to be just a speck of dust in the universe, unlikely to attract the attention of other civilizations."

Mao Zhengzhi nodded slowly.

Suddenly, his gaze fell on a line of data.

"1.9 times Earth's gravity?" Mao Zhengzhi frowned. "I doubt that's suitable for human habitation."

"That's why I called you here," Lü Yongchang said softly. "Can training enable humans to survive normally in this environment?"

Mao Zhengzhi pondered for a moment, then shook his head and said, "If we rely solely on training... Professor, that's very difficult to achieve."

Before Lü Yongchang could speak, he explained directly: "With a certain amount of training, the human body's muscles can easily adapt to such an environment."

"But the joints, internal organs, especially the heart and brain, may find it difficult to adapt."

"It's fine for short-term living, but for long-term living..."

Mao Zhengzhi sighed and shook his head repeatedly.

This action made Lü Yongchang's heart sink.

"Actually, in my opinion, the best option would be its satellite." Mao Zhengzhi turned to look at a corner of the holographic projection and continued, "With 0.56 times the Earth's gravity, it would only require a short period of adaptation training to relocate all of humanity to the surface to live."

Lü Yongchang frowned slightly: "Isn't there any other way?"

"This satellite... is too small for a Type III civilization."

"Once we decide to settle in this star system, I will order the lifting of all birth restrictions and encourage childbirth as much as possible."

"By then, the human population will have expanded rapidly, and this small satellite will probably not be able to meet the needs of human civilization."

At this point, Lü Yongchang hesitated for a moment, then lowered his voice and said, "Moreover, in the plan, it will be transformed into a planetary fortress integrating factories, ports, and military facilities."

"Hiss..." Mao Zhengzhi's expression immediately became much more serious.

As a high-ranking official in the Academy of Sciences, he was naturally aware of the importance of this plan.

It can be said that if an alien civilization were to attack, this modified natural satellite would be humanity's most powerful weapon of retaliation!

"If that's the case..." Mao Zhengzhi frowned even more deeply.

"Would a mechanical exoskeleton work?" Lu Yongchang suddenly asked.

Mao Zhengzhi nodded solemnly, then shook his head.

"It has some effect, but not a significant one."

"It can reduce the pressure on muscles, bones, and joints to some extent."

"But what about the internal organs..."

"I'm afraid it won't be of much use."

"Unless you turn the exoskeleton into a mechanical bed that can move freely."

"Only in this way can the burden on internal organs be significantly reduced."

Lü Yongchang couldn't help but smile wryly.

Are you kidding me?

If things really turn out like that, human civilization might as well live on a starship!
