Age of Cataclysm: I can light up the technology tree

More than ten minutes later.

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?" Mao Zhengzhi stood at the door and asked in a low voice with a bit of anxiety on his face.

He had just been reprimanded yesterday, and now he still had some psychological shadow.

Is it possible that I still need to be reprimanded today? !

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

Lu Yongchang raised his head and waved to Mao Zhengzhi.

"Academician Mao, come."

Upon hearing the call, Mao Zhengzhi swallowed slightly and moved a few steps into the room "as if he were dead".

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

"cough!"

He coughed lightly: "Don't worry, I'm not looking for you today about 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 stretched out his hand to wipe the sweat from his forehead, with a look of shame on his face: "Professor, actually, I thought about it for a long time last night."

"Oh?" Lu Yongchang saw Mao Zhengzhi's expression, and a smile appeared at the corner of his mouth, "What? You still can't let go of the human cloning technology, right?"

"No no no!"

Mao Zhengzhi shook his head like a rattle: "I 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 the wrong path and choose such a dangerous path."

Lu Yongchang smiled and nodded: "As long as you can figure it out."

"I'm looking for you today mainly for another thing."

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

A holographic image appeared in front of Mao Zhengzhi.

"This..." Mao Zhengzhi's face changed slightly and he lowered his voice and asked, "Whose physical examination report is this?"

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

"President."

Lu Yongchang gently spit out three words.

"Hiss!!!" Mao Zhengzhi gasped suddenly, causing the temperature in the office to drop by 0.00001 degrees Celsius.

"I remember the Congressman is only 85 years old. How could his body age like this?!"

Lu Yongchang's eyes showed a bit of helplessness: "It should be related to his previous life schedule."

"When he was on Earth, the burden on him was too heavy, and overexertion overtaxed his body functions."

“Currently, the next speaker of the People’s League has not yet been determined.”

"The Speaker believes that Councilor Hong is a good choice, but...it will probably take a lot of time to convince other members."

"Of course, out of selfishness, I also hope that the old chairman 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 the limit of human lifespan?"

"Not bad." Lu Yongchang nodded lightly.

Different from the past, thanks to the medical cabin, the congressman was in good health at this time and did not have any diseases in his body that would affect his lifespan.

He is simply aging.

This is also the most troublesome thing.

Aging is irreversible, this has been the experience of humans for thousands of years.

Mao Zhengzhi obviously knew this.

The moment he heard Lu Yongchang's words, his brows furrowed tightly.

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

This number is based on the cell division formula.

Simply put, every time a human cell divides, the telomeres at the end of the DNA decrease a little.

From this, based on the total length of telomeres, the number of cell divisions in a human's lifetime can be estimated.

50 times.

This is the division limit of normal human cells.

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

Based on this calculation, the maximum life span of human beings is 120 years.

Of course, there are other calculation methods.

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

According to this model calculation, the maximum life span of human beings is about 120-130 years old.

For another example, calculate based on the universal life span of mammals on Earth.

The lifespan of a mammal is 5-8 times its growth period.

The maximum human life span derived in this way is about 125 years old.

Either way, it proves a point.

No matter how advanced medical technology is, until the telomere problem is not solved, the maximum life span of humans will only be around 120 years old.

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

Mao Zhengzhi concluded in a low voice.

After saying that, he suddenly raised his head and looked directly at Lu Yongchang: "Professor, I have an idea."

…

A Xuannv 2 quietly sailed out of the "Earth" starship.

Unlike other Xuannv 2, the interior of this Xuannv 2 has been greatly modified - the entire cabin has been transformed into a small biological laboratory.

In Xuannv 2, Lu Yongchang, Fang Xu, and Mao Zhengzhi were wearing strict protective suits and sitting in the cockpit with serious expressions.

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

As soon as the voice fell, a strong recoil pressed the three people to the chair.

Xuannv II also headed straight for Proxima b.

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

Before Lu Yongchang spoke, Mao Zhengzhi on the side said: "Of course."

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

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

Fang Xu's face was bitter.

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

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

"Shut up." Lv Yongchang interrupted Fang Xu unhappily, "As my deputy, how can you not have this kind of tolerance?"

"I promised to take you to the biological laboratory to broaden your horizons two days ago."

"It's already this time, don't think about running away."

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

"Don't worry, you will be soon."

As he spoke, Lv Yongchang stared at the orange-yellow planet in the distance, and said casually: "As the second-in-command of the Academy of Sciences, these basic common sense still need to be mastered."

Fang Xu: "..."

Looking at Proxima b getting closer and closer, his face became more and more gray.
