Cataclysmic Era: I can unlock the tech tree

Earth

command center.

Precise data from the detector are displayed in a holographic projection directly in front of you.

Lü Yongchang noticed one set of data immediately.

"Carbon monoxide concentration 1.8%?"

"Is it that tall?"

A hint of surprise flashed in Lü 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's negligible!

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

such as.

When the carbon monoxide concentration reaches 0.06%, it can cause poisoning in a person within 1 hour.

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

This shows just how alarming the carbon monoxide concentration was on Ross 2!

"It is indeed a bit high."

Beside him, Fang Xu frowned and said in a low voice, "It seems to be another world that doesn't welcome humans."

"Perhaps there isn't even life on this planet."

Lu Yongchang raised an eyebrow, interrupting Fang Xu.

"That's not necessarily true."

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

Then, he turned his head again to look at the data in the holographic projection.

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

"Nitrogen is too stable, there's no oxygen, and the carbon monoxide concentration is so high, I don't believe life can grow in this godforsaken place!"

Lu Yongchang smiled, "How about we make a bet?"

Fang Xu nodded subconsciously: "A bet is a bet..."

As he spoke, his voice suddenly became a few decibels lower, and a hint of guilt appeared on his face.

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

After confirming the data again, he felt a surge of confidence.

"Let's gamble!"

"What's the stake?!"

The smile in Lü Yongchang's eyes deepened.

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

"The loser...will have to double their gravity chamber training for the next month!"

As he spoke, Lü Yongchang glanced at Cao Liangcai beside him and said, "Also, Lao Cao, don't forget the chicken leg rice you owe me."

Cao Liangcai: "???"

"Professor, please don't tease me," Cao Liangcai pleaded repeatedly. "Where am I supposed to get you chicken leg rice from Sandaokou University?"

Lü Yongchang shrugged: "Not now, but who knows, maybe later?"

After saying that, he looked at Fang Xu again: "So? Should I accept it or not?"

Faced with Lü Yongchang's "provocation," Fang Xu gritted his teeth and said, "I accept!"

"I refuse to believe that life can emerge in such an environment!"

"Just wait and see what happens in the gravity chamber!"

The bet is settled.

Don't forget.

"There was no oxygen on Earth at the beginning."

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

Fang Xu's face stiffened.

"Is that so?"

This thing really touched on a blind spot in his knowledge.

Lü Yongchang gestured towards He Bilin on the other side with his lip: "Look, if you don't believe me, go ask him."

Fang Xu turned his head stiffly toward He Bilin.

The answer I received was, of course, affirmative.

Finished!

A thought flashed through Fang Xu's mind.

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

"The results aren't out yet!"

"I still have a chance to turn things around!"

Upon hearing this, Lü Yongchang's smile widened.

"Zero, where is the probe?"

……

As everyone was talking, the rover on Ross 2 had already arrived at its destination—the winding river.

"Professor, the data from the probe has been transmitted back."

Lu Yongchang glanced at Fang Xu with a half-smile: "Zero, release the image data."

As soon as he finished speaking, the images transmitted from the probe vehicle's camera appeared in the holographic projection.

Looking at the ever-flowing river in the picture, Lü Yongchang's eyes revealed a touch of emotion.

When viewed from above, the river resembles a thin ribbon.

But when you actually get there, the river is quite large.

"Zero, approximately how wide is this river?"

Lu Yongchang asked casually.

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

"This section of the river is 67 kilometers wide."

Zero responded meticulously.

Lü Yongchang's face lit up with joy.

A river of this size can be considered to be neither a seasonal river nor a seasonal river.

Seasonal rivers are those that are greatly affected by seasonal factors.

During the dry season, rivers may even dry up completely.

The formation of early life requires a relatively stable environment.

This river can undoubtedly meet this need.

In contrast to Lü Yongchang's expression, Fang Xu looked increasingly ashen.

Lü Yongchang continued, "And the depth?"

There is no test data yet.

Lu Yongchang nodded slightly and gave the order: "Take some river water and send it back to the detector to examine it under a microscope."

"receive."

In the holographic projection, a robotic arm extends from the left side of the camera and plunges directly into the slightly murky river water.

Several tens of seconds later.

"Sampling complete."

Lu Yongchang nodded in satisfaction and looked again at Fang Xu, whose face was ashen.

"How is it?"

"Should we continue this bet?"

"Surrendering means you lose half the battle; all you need to do is increase your exercise by 50%."

"..." Fang Xu hesitated for a long time, then said "fiercely," "Continue!"

"I won't give up until the test results are in!"

A hint of regret flashed in Lü Yongchang's eyes.

To be honest, he wasn't very confident about the test results.

However... with his current physical condition, doubling the amount of exercise is not a difficult task.

……

The waiting time was long.

"Professor, the test results are in."

Zero's virtual image appeared beside Lü Yongchang and spoke softly.

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

Fang Xu, who was standing to the side, also cast an expectant look at Ling.

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

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

Lü Yongchang burst into loud laughter: "Hahaha, great!"

"Zero, produce the test report!"

When the test report appeared in the holographic projection, Fang Xu's last glimmer of hope was extinguished.

Don't forget.

"Starting today, your training volume will double."

As Lü Yongchang looked at the test report, he teased Fang Xu, whose face was ashen.

On the other side, Cao Liangcai looked at Fang Xu, who was sitting blankly in the chair, and shook his head with regret.

What a fine young man! Why did he have to make a bet with Lü Yongchang?
