"perhaps……"

Mao Zhengzhi's face was full of hesitation as he muttered to himself.

"What?" Lü Yongchang's ears twitched slightly, and he quickly asked, "Can you solve this problem?"

Seeing the expression on Mao Zhengzhi's face, Lü Yongchang had a guess in his mind, and he quickly lowered his voice: "Don't worry, just say it."

Faced with Lü Yongchang's questioning, Mao Zhengzhi sighed softly and uttered a few Chinese characters with a complicated expression.

"Genetic modification".

He finished speaking.

A profound silence fell.

Only the sound of their breathing remained by the porthole.

Lu Yongchang's eyes were full of struggle.

Genetic modification...

This technology has been strictly prohibited from being used on humans since the moment it appeared.

On the one hand, there will be many ethical issues.

on the other hand.

In the past, when biotechnology was not advanced enough, genetic modification often caused some unforeseen problems.

With humanity reaching Type II civilization and acquiring a large amount of biotechnology from the Proxima Centauri civilization, the likelihood of such a problem has been greatly reduced.

but!

The human body is, after all, a mystery.

Genes can also mutate.

Even level three or four civilizations cannot guarantee that no unexpected situations will occur!

"Maybe... we should just forget about it." Mao Zhengzhi let out a long sigh and said in a low voice.

"No!" Lü Yongchang gritted his teeth, a ruthless glint in his eyes. "We can't let this go!"

"Leaving aside the present, in the future, humanity will travel to even more distant galaxies!"

"We will encounter more and more extreme and harsh environments!"

"We'll let it go this time, but what about next time?!"

"Since leaving Earth, humans have ceased to be humans!"

"Embrace evolution, join evolution, and we can go further!"

Mao Zhengzhi stared blankly at Lü Yongchang in front of him, and subconsciously swallowed.

"Then, then we..."

So shocked was he that he didn’t even notice the slight tremor in his voice!

When questioned, Lü Yongchang slowly closed his eyes.

In just a moment, his consciousness returned to the familiar tech tree space.

The technology tree of the second-level civilization is almost complete.

Looking at the technology tree in front of him, Lü Yongchang's mind began to stir.

A thin, bright white line extends from near the branch representing biotechnology, stretching straight upwards!

The thin thread extends very quickly.

In the blink of an eye, the bright white line arrived at the boundary between the Level 2 and Level 3 civilizations.

A hidden cursor slowly appears.

[Join the glorious evolution: basic genetic modification technology]

The hidden cursor style is different from the regular cursor.

The background of a typical cursor is a bright white.

The background that hides the cursor is a bright green with intricate patterns.

Just like the background color of the tech tree space.

Back then, cloning technology, which was classified as a dangerous technology, was steeped in bloodshed.

Clearly, according to the system's evaluation criteria, genetic modification technology is not considered a dangerous technology.

On the contrary, in Lü Yongchang's mind, gene modification technology was like a "hidden quest" in a technology tree system.

He snapped out of his daze and opened his eyes abruptly.

"Begin related research!"

A glint flashed in Lü Yongchang's eyes, and he said decisively!

...

"professor."

"The probe has entered orbit and is about to begin its landing."

Zero's voice rang out from the side, drawing their attention.

Lu Yongchang waved his hand and pulled over the holographic projection from the side.

"Come on, let's take a look at this planet together."

"In the future, this will be our new home."

Mao Zhengzhi nodded with a wry smile and sat down on a chair to the side.

Compared to Earth, this barren planet in front of him really did not attract his interest.

However, this was, after all, Lü Yongchang's request.

He could only muster his spirits and look up at the holographic projection in front of him.

The projected image is shaking violently.

It is clear that the probe is now entering the atmosphere of this super-Earth.

Lu Yongchang, standing to the side, frowned deeply as he watched the rapidly flashing data on the screen.

"Is the atmosphere really that dense..." he murmured to himself.

Upon hearing this, Mao Zhengzhi glanced at the increasingly violently shaking screen with some concern.

Fortunately, as time went on, the shaking gradually lessened, and the image became clearer.

Lu Yongchang, standing beside him, also breathed a sigh of relief.

The landing site was chosen near the equator, close to the terminator.

The camera slowly pans down.

A large body of water, composed of countless small lakes, came into view before the two of them.

Each lake is separated by reefs of varying sizes.

The water area is not large.

It is at most the size of the Mediterranean Sea.

The camera quickly zooms out.

In the distance, several bodies of water of varying sizes and shapes can still be vaguely seen.

Seeing this, a hint of joy appeared in Lü Yongchang's eyes.

Liquid water has always played a significant role in human settlement selection.

As the detector descended, data gradually emerged.

Atmospheric pressure: 21.1 standard atmospheres

Average surface temperature: 28.14 degrees Celsius

[...]

Mao Zhengzhi raised an eyebrow.

"The atmospheric pressure is so high."

"It seems that humans are destined not to live outside the world."

Lü Yongchang did not quite agree with Mao Zhengzhi's statement.

He shook his head and said softly, "That's not necessarily true."

"In the future, perhaps we will have enough technology to terraform this planet."

Mao Zhengzhi smiled and nodded: "I hope so."

"If that day ever comes, I hope to be able to recreate the scenery on Earth."

Lu Yongchang glanced at Mao Zhengzhi beside him.

It's clear that Mao Zhengzhi doesn't believe this claim.

However, he didn't want to explain further.

Back on Earth, who could have imagined that human lifespans could reach hundreds of years, and that we could even bring thousands of starships to establish a home in a star system tens of light-years away?

...

Under the watchful eyes of Lü Yongchang and Mao Zhengzhi, the probe landed steadily on a reef beside the water.

The camera gradually moved upwards.

A stunningly beautiful scene unfolded before their eyes.

The lake is filled with reefs.

The sky at dusk had a bluish-purple hue.

In the upper right corner of the camera, a giant supermoon reflects the light from Gliese 555!

At the same time, the holographic image split in two.

Another probe heading to the crater also landed successfully and sent back image data.

On the left, in the blue-purple sky, there is also a huge supermoon.

On the right side of the camera, a tall mountain rises from the flat land.

At the top of the mountain, one can vaguely see rolling lava with a red glow!
