The bet was just a minor incident.
The key point, of course, is the water quality test report in front of us.
After all, this concerns the safety of the human community.
After carefully reviewing the report, Lü Yongchang breathed a long sigh of relief.
In several samples, only one simple single-celled organism was detected.
"It seems that life on this planet has only just begun to evolve."
Lu Yongchang said in a relaxed tone.
This is undoubtedly good news.
Normally, these primitive life forms do not pose a significant threat.
To be on the safe side, Lü Yongchang ordered more probes to be sent to Ross 2.
...
One month later.
3,000 dilapidated starships arrived at their destination.
Under Zero's precise control, these starships followed the orbit of Ross 2 and moved around Ross 154.
During this month-long journey, the remaining three interplanetary probes continued to orbit Ross 154.
Meanwhile, 90% of the optical and radio telescopes in the human fleet are pointed at this young star.
Ross 2 is also surrounded by hundreds of satellites with different functions.
After a month of intensive observation, neither Ross 154 nor Ross 2 showed any abnormalities.
This completely put Lu Yongchang's concerns at ease.
He believed that a normal, advanced civilization with the capability to strike stars would never deliberately hide its whereabouts for the sake of a mere Type II civilization!
It's like facing a group of ants; no one would hide in a corner to conceal their presence, just to deliver a "corner kill" to the ants.
"Landing on Ross 2 tomorrow!"
Looking out the porthole at the solid planet with rings, Lü Yongchang smiled with anticipation.
...
The next day.
Hundreds of Xuan Nu II ships sailed out of the Earth Port and headed straight for the distant Ross II planet!
On this day, Ross 2, which had been lonely for countless years, welcomed its first visitors.
The high temperatures generated by the Hall thrusters created strange patterns in the upper atmosphere.
Hundreds of rainbows appeared in the azure sky!
After traversing thousands of mountains and rivers, the Xuan Nu No. 2 aircraft group finally arrived at the "city-building site" selected by Lü Yongchang.
The hatch slowly opened.
Researchers, robots, supply transport vehicles...
They filed out.
...
Wearing a spacesuit, Lü Yongchang stomped his feet hard, feeling the solid ground beneath his feet.
The ground feels slightly different from that of Proxima Centauri.
Due to the influence of various organisms, the land texture of Proxima Centauri is more like that of Earth.
The land on Ross II made him feel like he was back on Mars.
Let's go.
Lu Yongchang called out to Fang Xu beside him, "Let's go get the samples."
"Once we've determined that these indigenous people pose no threat to humans, we can begin building the city."
Fang Xu responded and quickly walked towards the planetary landing vehicle to the side.
Thanks to a month of training in the gravity chamber, Fang Xu's steps were incredibly solid, without the slightest feeling of unsteadiness.
"Smack!"
Lu Yongchang walked around behind Fang Xu and gently patted him on the shoulder: "Not bad."
"It seems that training in the gravity chamber is quite effective!"
Upon hearing the voice coming from the team's radio, Fang Xu abruptly stopped what he was doing.
He turned his head and gave Lü Yongchang, who was all smiles, a resentful look.
How could it be useless?!
In the first few days after he entered the gravity chamber, he even slept in the medical pod!
If it weren't for the medical pod, Fang Xu even doubted whether he could have successfully participated in this landing operation!
“…Let’s go,” Fang Xu said clumsily, trying to change the subject. “Let’s go get the samples.”
Seeing Fang Xu's embarrassed expression, Lü Yongchang couldn't help but chuckle.
He didn't expose Fang Xu's thoughts and climbed directly onto the tall planetary landing vehicle.
Considering the various complex terrains that may exist on the planet's surface, the planetary lander possesses extremely strong off-road capabilities.
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 carbide material used in Starships.
To ensure the safety of researchers, the designers even equipped it with two small electromagnetic guns and one small laser gun!
As soon as Lü Yongchang climbed into the cockpit, he noticed Fang Xu's strange look.
"how?"
"...You can drive this thing?"
Lu Yongchang calmly nodded: "Of course!"
"?!" Fang Xu exclaimed in surprise, "When did you learn that? I remember this car's design drawings were just released a month ago!"
Lu Yongchang chuckled and expertly pulled out a seatbelt from the side, then reached out and pressed a button on the side.
The vehicle starts.
The dashboard lights up slowly.
"Zero, you take control."
Fang Xu: "..."
...
After retrieving the sample, Lü Yongchang returned directly to Xuan Nu II without any delay.
Inside the cabin of the Xuan Nu II aircraft, which had been converted into a biological laboratory, Lü Yongchang, dressed in protective clothing, skillfully carried out a series of testing procedures.
Having explored Mars and Proxima Centauri b, he became increasingly adept at dealing with extraterrestrial life.
When all the test results came out, Lü Yongchang breathed a slight sigh of relief.
"There's nothing seriously wrong."
"They are just some simple organisms similar to cyanobacteria."
“Through the treatment of the nanofiltration device, this river water can even be drunk directly.” Lu Yongchang said softly, looking at the various indicators on the holographic projection. “It even contains many minerals that are beneficial to humans.”
Nanofiltration devices, simply put, are filtration systems based on nanorobots.
This device is widely used on Proxima Centauri b to completely eliminate various extraterrestrial microorganisms contained in water sources.
"So, how do these single-celled organisms survive in this environment?" Fang Xu asked with a curious expression.
As Lü Yongchang looked through the holographic projection in front of him, he explained, "Have you ever heard of nitrogen-fixing plants?"
Fang Xu frowned and pondered for a long time: "You mean... soybeans?"
Lu Yongchang glanced at Fang Xu helplessly.
"You've hit the nail on the head."
"On Earth, nitrogen-fixing plants are divided into three categories."
"The first two types are plants that live in symbiosis with rhizobia and Frankincense."
"There is another type, which is a plant that lives in symbiosis with cyanobacteria."
"These single-celled organisms can absorb nitrogen from the atmosphere, a process that is somewhat similar to nitrogen-fixing cyanobacteria."
"Tests show that they can absorb nitrogen and convert it into nitrogen compounds."
"At the same time, it can also release compounds such as amino acids and polypeptides during the growth process."
"Compared to our solar system, this star system is too young."
"Perhaps, in a billion years, some complex life forms will appear on this planet."
