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

He remembered what he had said to Mao Zhengzhi two days ago.

Proxima civilization with an average age of [-] years!

A bright light flashed in his eyes, and he said in a deep voice, "Ling, let Mao Zhengzhi come to the office to find me."

"Don't alarm anyone."

After speaking, he opened his legs and strode towards his office.

Chapter 293 Telomeres

After ten minutes.

The office door opened quietly.

"Professor, Academician Mao is here."

Zero's reminder sounded at the same time.

"Professor Lu, are you looking for me?" Standing at the door, Mao Zhengzhi asked in a low voice with a look of anxiety on his face.

He was just reprimanded yesterday, and now he still has some psychological shadows.

Is it possible that I still have to be trained today? !

Thinking of what might happen next, Mao Zhengzhi felt a bit of bitterness in his heart.

Lu Yongchang raised his head and waved to Mao Zhengzhi.

"Academician Mao, come."

Hearing the call, Mao Zhengzhi swallowed slightly, and moved a few steps into the room "regarding death as if going home".

Seeing Mao Zhengzhi's twitchy movements, Lu Yongchang couldn't help being stunned, and then remembered some "unpleasant" things that happened yesterday.

"cough!"

He coughed lightly: "Don't worry, I'm not looking for you today because of human cloning technology."

Hearing this, Mao Zhengzhi breathed a sigh of relief, and sat down on the chair in front of Lu Yongchang.

"Click."

The crisp sound from the electromagnetic adsorption device sounded.

He reached out and wiped the sweat on his forehead, with a look of shame on his face: "Professor, actually, I thought about it for a long time last night."

"Oh?" Seeing Mao Zhengzhi's expression, Lu Yongchang smiled, "Why? You can't let go of the human cloning technology, right?"

"No no no!"

Mao Zhengzhi shook his head like a rattle: "I have thought about it carefully, and it is true that, as you said, human cloning technology has too many hidden dangers."

"For the current human civilization, there is absolutely no need to take a slant and choose such a dangerous path."

Lu Yongchang smiled and nodded: "It's good if you can figure it out."

"I came to you today mainly for another matter."

As he spoke, he stretched out his hand across the air.

A holographic image appeared in front of Mao Zhengzhi.

"This..." Mao Zhengzhi's face changed slightly, and he asked in a low voice, "Whose medical examination report is this?"

As the developer of the medical cabin, Mao Zhengzhi naturally knew what these data meant.

"Chairman."

Lu Yongchang spit out three words lightly.

"Hiss!!!" Mao Zhengzhi let out a sharp gasp, causing the temperature in the office to drop by 0.00001 degrees Celsius.

"I remember that the chairman of the congress is only 85 years old, how could his body age like this?!"

Lu Yongchang showed a bit of helplessness in his eyes: "It should be related to his previous life and rest."

"When he was on Earth, the burden on him was too heavy, and his body functions were overdrawn by overwork."

"Currently, the next chairman of the People's Federation has not yet been determined."

"The chairman of the council thinks that Councilor Hong is a good choice, but... it will probably take a lot of time to convince other councilors."

"Of course, out of selfishness, I also hope that the old congressman can live a little longer."

Mao Zhengzhi instantly understood what Lu Yongchang meant.

He looked at Lu Yongchang solemnly: "So, you want to use the biotechnology of Proxima Centauri civilization to break through the limit of human life span?"

"Not bad." Lu Yongchang nodded lightly.

Unlike in the past, thanks to the medical cabin, the chairman of the council is in good health at this time, and there is no disease in his body that would affect his lifespan.

He's just plain old.

This is also the most troublesome thing.

Aging is irreversible, this is human experience for thousands of years.

Mao Zhengzhi obviously knew this too.

The moment he heard Lu Yongchang's words, he frowned tightly.

According to current theoretical calculations, the longest human life expectancy is about 120 years old.

This number is derived from the cell division formula.

Simply put, each time a human cell divides, the number of telomeres at the end of the DNA shrinks a little.

Thus, based on the total length of telomeres, the number of cell divisions in human life can be estimated.

50 times.

This is the division limit of normal human cells.

The lifespan of each generation of cells is about 2.4 years.

Calculated in this way, the limit life span of human beings is 120 years old.

Of course, there are other calculation methods.

For example, the Gompertz model, a mathematical model used to describe the extinction law of biological populations.

According to the calculation of this model, the limit lifespan of human beings is about 120-130 years old.

For another example, calculate according to the general lifespan law of mammals on the earth.

Mammals live 5-8 times their growth period.

The human limit lifespan introduced in this way is about 125 years old.

Either way, it proves a point.

No matter how advanced the medical technology is, before the telomere problem is solved, the maximum human life span will only be around 120 years old.

"So ... we have to start with the telomeres."

Mao Zhengzhi concluded in a low voice.

After finishing speaking, he suddenly raised his head and looked straight at Lu Yongchang: "Professor, I have an idea."

……

A Xuannv-[-] quietly sailed out of the [Earth] starship.

Unlike other Xuannv No. [-], the interior of this Xuannv No. [-] has been greatly remodeled—the entire cabin has been converted into a small biological laboratory.

In Xuannv No. [-], Lu Yongchang, Fang Xu, and Mao Zhengzhi were wearing tight protective clothing and sitting in the cockpit with serious expressions.

"Zero, go directly to Proxima b." Lu Yongchang gave his order.

After the words fell, a strong recoil force pressed the three of them firmly onto the chairs.

Xuannv-[-] also headed straight for Proxima b.

"Yongchang..." Fang Xu's voice sounded on the radio in the team, "Do you really have to go to the surface of Proxima b for experiments?"

Before Lu Yongchang could speak, Mao Zhengzhi beside him said, "Of course."

"At that time, we will also dissect the bodies of several Proxima Centauri for sampling."

"You don't want to see their organs flying all over the sky, do you?"

Fang Xu's face turned bitter.

Thinking of the scene of the flying organs, he subconsciously vomited.

"Yongchang, I think the command center may need me..."

"Shut up." Lu Yongchang interrupted Fang Xu angrily, "As my deputy, how can I not be able to bear this?"

"Two days ago, I agreed to take you to the biology laboratory to open your eyes."

"It's time now, don't even think about running away."

The expression on Fang Xu's face became more and more bitter: "But, but I'm not a biology major either!"

"Don't worry, you'll be there soon."

Speaking, Lu Yongchang stared at the orange planet in the distance, and said casually: "As the second leader of the Academy of Sciences, you still need to master these basic common sense."

Fang Xu: "..."

Looking at the approaching Proxima b, his face became more and more gray.

Chapter 294 Anatomy

Proxima b.

In front of the No. [-] dungeon hut, a Xuannv No. [-] landed slowly.

Under Zero's control, more than a dozen robots carried more than a dozen metal coffins, quietly waiting at the landing point of Xuannv No. [-].

In the metal coffin, there are naturally carefully selected corpses of Proxima Centauri.

After layers of screening, the dozen or so corpses are not only extremely "fresh", but also contain various stages of Proxima Centauri and Marus.

The hatch of Xuannv No. [-] slowly opened, and more than a dozen robots carried the coffins in one file after another.

The three of Lu Yongchang were already wearing tight protective clothing and waiting by the test bench.

They need to dissect these more than ten corpses, and then collect samples from various parts.

With the help of the robot, the first metal coffin was slowly opened.

Lu Yongchang carefully examined the corpse in front of him.

The skin is loose, the carapace on the back is dull, and the body is thin and curled up...

An elderly Proxima Centaur.

The body was well preserved without a trace of corruption.

"I don't know whose corpse this is, but I can still enjoy this method of preservation..." Lu Yongchang muttered to himself with a hint of doubt in his eyes.

Before he finished speaking, a holographic image appeared in front of Lu Yongchang.

It shows Zero's identification information found in the central computer database.

【Name: Augustus】

[Identity: Chief Lyle of Proxima Academy of Sciences]

【Age: 639 years old】

[Death time: Earth Calendar 2147.3.6]

[Honors and achievements: ...]

Looking at the dense information in front of him, Lv Yongchang opened his mouth slightly, not knowing what to say for a while.

"Yongchang, this old man has the same identity as you." Fang Xu's voice came from the team radio.

Lu Yongchang turned his head and glanced at Fang Xu.
