It's reasonable for me to have a two-way foil for a second-level civilization, right?

In the center of the lake, there are still several islands in the middle of the lake.

On the left side of the plain, a wide river flows slowly.

"It's here!"

There was some joy in Lu Yongchang's eyes: "The address of the central city is here!"

As he spoke, he recorded the coordinates displayed on the detector.

Regarding Lu Yongchang's proposal, everyone present nodded in agreement.

Although there may be indigenous microorganisms in the water, this is no longer a problem for human civilization at present.

The probe descends slowly.

Three brackets popped out from the side, holding it up firmly.

Afterwards, the side hatch of the spherical detector slowly opened.

A probe vehicle loaded with sophisticated detection instruments slowly drove out of it.

[Atmospheric composition: 97% nitrogen, 1.8% carbon monoxide, 0.6% carbon dioxide, 0.4% water vapor...]

command center.

Strips of precise data from the detectors are presented in the holographic projection directly ahead.

Lu Yongchang noticed a set of data immediately.

"1.8% carbon monoxide concentration?"

"Is it that high?"

There was a bit of surprise in Lu Yongchang's eyes.

There is actually a small amount of carbon monoxide in the earth's atmosphere.

However, its concentration is extremely low!

So low that it can be ignored!

However, once the concentration rises, this colorless, odorless and highly toxic gas will show extremely strong toxicity!

such as.

When the concentration of carbon monoxide reaches 0.06%, it can cause human poisoning within 1 hour.

When its concentration reaches 0.32%, within 30 minutes, humans will fall into a coma and die.

From this we can see how amazing the concentration of carbon monoxide on Ross 2 is!

"It's really a bit high."

On the side, Fang Xu frowned and said in a low voice: "It seems that this is another world where humans are not welcome."

"Perhaps, there is no life on this planet."

Lu Yongchang raised his eyebrows and interrupted Fang Xu's words.

"Not necessarily."

Fang Xu stared blankly at Lu Yongchang: "Are you sure?"

Then, he turned his head and looked at the data in the holographic projection again.

After confirming that it was correct, he shook his head repeatedly and said, "Impossible, absolutely impossible!"

"The nature of nitrogen is too stable, there is no oxygen, and the concentration of carbon monoxide is so high, I don't believe that life can be born in this ghost place!"

Lu Yongchang smiled at the corner of his eyes: "Why don't you make a bet?"

Fang Xu nodded subconsciously: "If you bet, bet..."

As he spoke, his voice suddenly became softer, and a trace of guilt appeared on his face.

He frowned tightly, and turned to look at the holographic projection again.

After confirming the data again, a little confidence surged in his heart.

"Bet!"

"What's the bet?!"

Lu Yongchang smiled even more.

He pondered for a moment, then said, "Just bet on the amount of training."

"The loser... in the next month, the training volume of the gravity chamber will be doubled!"

As he spoke, Lu Yongchang glanced at Cao Liangcai who was at the side: "Also, Lao Cao, don't forget the chicken leg meal you owe me."

Cao Liangcai: "???"

"Professor, please stop playing with me." Cao Liangcai begged for forgiveness, "Where can I get you the chicken leg rice from Sandaokou University?"

Lu Yongchang shrugged: "Not now, maybe in the future?"

After finishing speaking, he looked at Fang Xu again: "How is it? Do you want to answer it?"

Faced with Lv Yongchang's "provocation", Fang Xu gritted his teeth: "Accept!"

"I don't believe it, such an environment can give birth to life!"

"Just wait and cry in the gravity cabin!"

The bet is established.

The corner of Lu Yongchang's mouth was raised, revealing a mysterious smile.

"do not forget."

"At the beginning of the earth, there was no oxygen."

"Also, the concentration of carbon monoxide in the atmosphere is not low."

Fang Xu's face froze.

"Yes, is there such a thing?"

This thing really touched his blind spot of knowledge.

Lu Yongchang pouted at He Bilin on the other side: "Here, if you don't believe me, you can ask?"

Fang Xu turned his head stiffly to look in He Bilin's direction.

What I got was naturally an affirmative answer.

Finished!

A thought flashed in Fang Xu's mind.

Thinking of what he was going to face next, which was double the amount of training in the gravity chamber, a thin layer of cold sweat had already appeared on his forehead.

"Also, there is no result yet!"

"I still have a chance to come back!"

Hearing this, Lu Yongchang smiled even more.

"Zero, where did the probe go?"

……

While everyone was talking, the rover on the Ross 2 star had arrived at its destination—the meandering river.

"Professor, the data from the rover has been sent back."

Lu Yongchang glanced at Fang Xu with a half-smile: "Ling, let's release the image data."

As soon as the voice fell, the holographic projection appeared in the picture sent back by the probe car's camera.

Looking at the endlessly flowing river in the picture, Lu Yongchang's eyes showed a bit of emotion.

When viewed from a high altitude, the river looks like a thin ribbon.

But when it comes to the present, the scale of this river is still quite large.

"Zero, how wide is this river?"

Lu Yongchang asked casually.

"The average width is 82 kilometers, and the widest point reaches 230 kilometers."

"The width of this section of the river is 67 kilometers."

Zero responded sternly.

Lu Yongchang looked happy.

For a river of this size, it is basically certain that it does not belong to that kind of seasonal river.

The so-called seasonal rivers refer to rivers greatly affected by seasonal factors.

Once the dry season comes, the river will even stop flowing and dry up.

The formation of early life requires a relatively stable environment.

This river can undoubtedly meet this demand.

Contrary to Lu Yongchang's expression, Fang Xu's expression became more gray and defeated.

Lu Yongchang continued to ask: "What about the depth?"

"There is no testing data yet."

Lu Yongchang nodded slightly, and gave an order: "Take part of the river water, send it back to the detector, and use a microscope to look at it."

"receive."

In the holographic projection, a robotic arm protrudes from the left side of the camera, straight into the slightly turbid river water.

Dozens of seconds later.

"Sampling complete."

Lu Yongchang nodded in satisfaction, and looked at Fang Xu again, who was ashen-faced.

"How about it?"

"Do you want to continue this bet?"

"Surrender loses half, you just need to increase the amount of exercise by 50%."

"..." Fang Xu struggled for a while, and said "viciously", "Continue!"

"I won't admit defeat before the test results come out!"

A trace of regret flashed in Lu Yongchang's eyes.

To be honest, he was not sure about the test results.

It's just... With his current physique, it's not difficult to double the amount of exercise.

……

The waiting time is long.

"Professor, the test results are back."

The avatar of Zero appeared beside Lu Yongchang, and said softly.

Lu Yongchang's expression brightened, and he asked hurriedly, "How is it? Is there anything in the water?"

Fang Xu on the side also cast an expectant look at Ling.

"Under microscope observation, a small number of single-celled organisms were found in the water body."

Zero announced the result of the bet in a calm tone.

Lu Yongchang laughed loudly and said, "Hahahaha!"

"Zero, take out the test report!"
