The bet is just a small episode.

The focus is naturally on the water body inspection report in front of you.

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

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

In several samples, only a single-cell organism with 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.

Usually, the threat to these primitive lives 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 the precise control of zero, these starships followed the orbit of the Ross 2 star and moved around Ross 154.

During this month's voyage, the remaining three interstellar probes still revolve around Ross 154.

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

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

After a month of high-intensity observation, neither Ross 154 nor Ross 2 showed any abnormality.

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

He believed that a normal high-level civilization with the ability to strike stars would never deliberately hide his whereabouts for a mere second-level civilization!

It’s like when facing a group of ants, no one will hide in the corner and hide their own traces of existence just to give the ants a “corner kill”.

"Tomorrow, land on Ross 2 Star!"

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 II ships sailed out of the [Earth] port and headed straight towards the Ross 2 star in the distance!

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

The high temperature brought by the Hall thruster forms strange patterns in the high atmosphere.

Hundreds of long rainbows appeared in the blue sky!

The Xuannv No. 2 aircraft group crossed thousands of mountains and rivers and finally arrived at the "city building point" selected by Lu Yongchang.

The hatch door slowly opened.

Researchers, robots, material transport vehicles...

Out in a row.

...

Lu Yongchang was wearing a space suit and stomped his feet hard, feeling the touch of the solid land.

It is slightly different from the land of Proxima Centauri.

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

The land of Ross 2 made him feel like he was returning to Mars.

"Let's go."

Lu Yongchang greeted Fang Xu beside him: "Let's go and take samples."

“As long as we make sure that these indigenous people have no effect on humanity, we can start building cities.”

Fang Xu responded and quickly walked towards the planet landing car beside him.

Thanks to the one-month-long gravity cabin training, Fang Xu's steps seemed extremely solid and without any sense of silence.

"Bang!"

Lu Yongchang walked around behind Fang Xu and patted his shoulder gently: "It's not bad."

"It seems that gravity cabin training is quite useful!"

Listening to the sound coming from the radio in the team, Fang Xu's movements suddenly paused.

He turned his head and glanced at Lu Yongchang with a resentful look on his face.

Can it be useless?!

The days after entering the gravity cabin, 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 participate in this login operation successfully!

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

Looking at Fang Xu's awkward appearance, Lu Yongchang burst into laughter.

He did not expose Fang Xu's thoughts and climbed onto the tall planetary landing car.

Considering the various complex terrain that may exist on the planet's surface, planetary landing vehicles have extremely strong off-road performance.

This plus version of the "off-road vehicle" uses small nuclear fusion as energy, and the body is made of the same carbonaceous material as Starship.

In order to ensure the safety of scientific researchers, the designers even installed two small electromagnetic guns and one small laser gun for them!

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

"how?"

"...You can drive this thing?"

Lu Yongchang nodded calmly: "Of course!"

"??!" Fang Xu exclaimed, "When did you learn it? I remember that the design drawings were just released a month ago?!"

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

Vehicle starts.

The dashboard lights up slowly.

"Zero, you'll control it."

Fang Xu: “…”

...

After retrieving the sample, Lu Yongchang did not stop at all and went back to Xuannv No. 2.

In the cabin of Xuannv No. 2, which was converted into a biology laboratory, Lu Yongchang wore protective clothing and started a series of inspections with ease.

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

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

“No big problem.”

"It's just some simple organisms that resemble cyanobacteria."

"Through the treatment of nanofiltration devices, these river water can even be consumed directly." Lu Yongchang looked at the various indicators in the holographic projection and whispered, "It even contains a lot of minerals that are beneficial to humans."

A nanofiltration device, simply put, is a filter system based on a nanorobot.

This device is widely used in Proxima Centauri, which is used to completely eliminate various alien microorganisms contained in water sources.

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

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

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

Lu Yongchang glanced at Fang Xu helplessly.

"I've said it a little bit."

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

"The first two are plants that symbiotic with rhizobia and Frankella."

"There is another type of plant that symbiotically with cyanobacteria."

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

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

"At the same time, during the growth process, compounds such as amino acids and polypeptides can be released."

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