More than ten minutes later.

The office door quietly opened.

"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, with a hint of nervousness on his face, and he asked in a low voice.

He was scolded just yesterday, but he still has some psychological shadows.

Could it be that I will be trained today?!

Thinking of the possible scenes next, a hint of bitterness appeared in Mao Zhengzhi's 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 "to die as if he was home".

Looking at Mao Zhengzhi's hesitant actions, Lu Yongchang couldn't help but be stunned, and then remembered some "unpleasant" events that happened yesterday.

"cough!"

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

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

"Click."

A crisp sound from the electromagnetic adsorption device sounded.

He reached out to wipe the sweat from his forehead, with a hint of shame on his face: "Professor, in fact, I thought for a long time last night."

"Oh?" Lu Yongchang saw Mao Zhengzhi's expression and a smile appeared on the corner of his mouth, "Why? Can't he still not let go of that clone technology, right?"

"No, no!"

Mao Zhengzhi shook his head like a rattle: "I thought about it carefully. As you said, cloning technology has too great a risk."

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

Lu Yongchang smiled and nodded: "Just think it through."

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

As he said that, he reached out and flew through 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 physical examination report is this?"

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

"President of Parliament."

Lu Yongchang gently spoke three words.

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

"I remember that the Chairman of the Councilor was only 85 years old, how could his body age like this?!"

Lu Yongchang's eyes showed a little helplessness: "It should be related to his previous lifestyle."

"When on Earth, the burden on him was too heavy, and overwork overdrawing his physical functions."

"At present, the next chairman of the People's Federation has not yet been confirmed."

"The Chairman of Congress believes that Member Hong is a good choice, but... it probably takes a lot of time to convince other members of the parliamentary."

"Of course, out of selfishness, I also hope that the old president of parliament can live more time."

Mao Zhengzhi instantly understood what Lu Yongchang meant.

He looked at Lu Yongchang with a serious expression: "So, do you want to use the biotechnology of Proxima Centar civilization to break through the limit of human life span?"

"Not bad." Lu Yongchang nodded slightly.

Unlike in the past, I was blessed with the medical cabin. At this time, the president of the council was in good health and there was no disease in his body that would affect his lifespan.

He is just aging.

This is also the most troublesome thing.

Aging is irreversible, this is the experience of thousands of years of human beings.

Mao Zhengzhi obviously knew this.

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

According to current theoretical calculations, the longest life span of humans is about 120 years old.

This number is derived from the cell division formula.

Simply put, every time human cells divide, the telomeres at the end of DNA will be reduced a little.

From this, 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 is about 2.4 years.

By this calculation, the ultimate life span of human beings is 120 years old.

Of course, there are other calculation methods.

For example, the Gunpertz model is a mathematical model used to describe the law of biological population extinction.

According to this model, the ultimate life span of humans is about 120-130 years old.

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

Mammals live 5-8 times their growth period.

The ultimate human life span introduced in this way is about 125 years old.

Either way, it proves a little bit.

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

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

Mao Zhengzhi concluded in a low voice.

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

...

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

Unlike other Xuannv II, the interior of this Xuannv II has undergone a major transformation - the entire cabin has been transformed into a small biological laboratory.

Among the second number of Xuannv, Lu Yongchang, Fang Xu and Mao Zhengzhi were wearing tight protective suits and sitting in the cockpit with a serious expression.

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

As he finished speaking, a powerful recoil pressed the three of them tightly on the chair.

Xuannv also drove straight towards Proxima Centauri.

"Yongchang..." Fang Xu's voice sounded on the team's radio, "Do you really have to go to Proxima Centauri to do experiments?" www.bǐqυgetν.℃ǒm

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

"We will also dissect several Proxima Cell bodies 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's words with annoyance, "As my deputy, how can I not have this little tolerance?"

"I promised to take you to the biology laboratory two days ago to open my eyes."

"It's now, don't think about escaping in the last battle."

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

"Don't worry, you'll be there right away."

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

Fang Xu: “…”
