Age of Cataclysm: I can light up the technology tree

The bet is just a small episode.

The focus is naturally still on the water body detection report in front of us.

After all, this is related to the safety of the human population.

After carefully reviewing the report, Lu Yongchang breathed a long sigh of relief.

In several samples, only one single-celled organism with a simple structure was detected.

"It seems that life on this planet has just begun to evolve."

Lu Yongchang said in a relaxed tone.

This is undoubtedly good news.

Normally, the threat to these primitive beings is not high.

To be on the safe side, Lu Yongchang ordered more detectors to be sent to Ross 2.

…

One month later.

3,000 starships with dilapidated surfaces arrived at their destination.

Under Zero's precise control, these starships followed the orbit of the Ross 2 star and moved around Ross 154.

During this one-month voyage, the remaining three interstellar probes are still moving around Ross 154.

At the same time, 90% of the optical telescopes and radio telescopes of the human fleet are pointed at this young star.

The Ross 2 star is also surrounded by hundreds of satellites with different functions.

Under intensive observation for a month, neither Ross 154 nor Ross 2 showed any abnormalities.

This also made Lu Yongchang completely let go of his worries.

He believed that a normal advanced civilization with the ability to attack stars would never deliberately hide its whereabouts for a mere second-level civilization!

This is like, facing a group of ants, no one will hide in a corner to hide traces of their existence, just to give the ants a "corner kill".

"Tomorrow, land on Ross 2!"

Looking at the solid planet with star rings outside the porthole, Lu Yongchang showed an expectant smile on his face.

…

The next day.

Hundreds of Xuannv 2 ships sailed out of the [Earth] port and headed straight for the Ross 2 star in the distance!

On this day, Ross 2, which had been lonely for countless years, welcomed its first batch of tourists.

The high temperature brought by the Hall thruster formed strange lines in the upper atmosphere.

In the blue sky, hundreds of rainbows appeared!

The Xuannv 2 fleet crossed thousands of mountains and rivers and finally arrived at the "city construction point" selected by Lu Yongchang.

The hatch opens slowly.

Scientific researchers, robots, material transport vehicles...

Filed out.

…

Lu Yongchang was wearing a spacesuit and stamped his feet vigorously, feeling the touch of the solid earth.

It feels slightly different from the land of Proxima Centauri.

Due to the influence of various organisms, the texture of Proxima Centauri's land is more like that of the Earth.

The land on Ross 2 made him feel like he was back on Mars.

"Let's go."

Lu Yongchang greeted Fang Xu next to him: "Let's go get samples."

"As long as we are sure that these indigenous people have no impact on humans, we can start building cities."

Fang Xu responded and quickly walked towards the planetary landing vehicle on the side.

Thanks to the month-long exercise in the gravity chamber, Fang Xu's footsteps seemed extremely solid, without any sense of emptiness.

"Crack!"

Lu Yongchang walked around behind Fang Xu and patted his shoulder gently: "Not bad."

"It seems that the gravity chamber exercise is quite useful!"

Listening to the voice coming from the team's radio, Fang Xu's movements suddenly stopped.

He turned his head and glanced resentfully at Lu Yongchang, who was smiling.

Can it be useless? !

In the first few days after entering the gravity chamber, he even slept in the medical cabin!

If it weren't for the help of the medical cabin, Fang Xu even doubted whether he could successfully participate in the landing operation!

"...Let's go." Fang Xu changed the subject in a clumsy way, "Let's go take samples."

Seeing Fang Xu's embarrassed look, Lu Yongchang burst into laughter.

He didn't reveal Fang Xu's thoughts and climbed directly onto the tall planetary landing vehicle.

Taking into account the various complex terrains that may exist on the planet's surface, the planetary landing vehicle has extremely strong off-road performance.

This Plus version of the "off-road vehicle" uses small-scale nuclear fusion as its energy source, and its body is made of the same carbyne material as the starship.

In order to ensure the safety of scientific researchers, the designers even installed two small electromagnetic guns and a small laser cannon!

As soon as he got into the cockpit, Lu Yongchang saw Fang Xu's strange eyes.

"how?"

"...You know how to drive this thing?"

Lu Yongchang nodded calmly: "Of course!"

"??!" Fang Xu was amazed, "When did you learn this? I remember didn't the design drawings of this car just come out a month ago?!"

Lu Yongchang sneered, pulled out the seat belt from one side very skillfully, and then reached out to press a button on the side.

The vehicle starts.

The dashboard slowly lights up.

"Zero, you take control."

Fang Xu: "..."

…

After retrieving the sample, Lu Yongchang returned directly to Xuannv No. 2 without stopping.

In the cabin of Xuannv 2, which was converted into a biological laboratory, Lu Yongchang wore protective clothing and carried out a series of inspections with ease.

After experiencing Mars and Proxima Centauri b, he became more and more skilled in handling extraterrestrial life.

When all the test results came out, Lu Yongchang breathed a sigh of relief.

"No big deal."

"Just some simple organisms like cyanobacteria."

"Through the treatment of the nanofiltration device, these river waters can even be drunk directly." Lv Yongchang looked at the various indicators in the holographic projection and said softly, "It even contains a lot of minerals that are beneficial to humans."

Nanofiltration device, in simple terms, is a filtration system based on nanorobots.

This device is widely used on Proxima b to completely eliminate various alien microorganisms contained in the water source.

"So, how do these single-cell organisms survive in this environment?" Fang Xu asked curiously.

While flipping through the holographic projection in front of him, Lv Yongchang explained: "Have you heard of nitrogen-fixing plants?"

Fang Xu frowned and thought for a while: "You mean...soybeans?"

Lv Yongchang glanced at Fang Xu helplessly.

"That's a little bit right."

"On Earth, nitrogen-fixing plants are divided into three categories."

"The first two are plants that live in symbiosis with Rhizobia and Frankia."

"The other is a plant that lives in symbiosis with cyanobacteria."

"These single-cell organisms can absorb nitrogen from the atmosphere, and the process... is somewhat similar to nitrogen-fixing cyanobacteria."

"Tests show that they can absorb nitrogen and convert it into nitrogen compounds."

"At the same time, during the growth process, they can also release compounds such as amino acids and peptides."

"Compared to the solar system, this star system is too young."

"Perhaps, after waiting for another billion years, some complex life forms will appear on this planet."
