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

He saw Su Yutong staring at him.

After debating for a while, Lu Yongchang chose Congxin—he silently bent down and picked up the bag of aerospace food.

"Cough! I suddenly feel a little hungry..." A trace of embarrassment flashed across his face, and he quickly put the packaging bag into his pocket, "I'll take it to the biology laboratory to eat, okay?"

Su Yutong didn't speak, but silently moved out of the way.

……

outside the biology lab.

Mao Zhengzhi hurriedly ran towards the door of the laboratory.

"how is this possible……"

"It was really solved in a week???"

"Are you TN kidding me?!"

While hurrying, he whispered something in his mouth.

Suddenly, he stopped his steps.

At the main entrance of the laboratory, a familiar figure came into his sight.

However, this image...

Mao Zhengzhi looked at Lu Yongchang in front of him with a strange expression: "Professor, who is this?"

"Huh?" Lu Yongchang had messy hair, holding two space food bags in his hands, and a bag of drinking water in his mouth, looking up at him with a confused expression.

Seeing Mao Zhengzhi, Lu Yongchang swallowed significantly faster.

"..."

Choked.

Lu Yongchang's face flushed slightly, and he took a sip of drinking water.

"Professor, no, no, take your time!"

Mao Zhengzhi walked up to Lu Yongchang with a wry smile, reached out and patted his back lightly.

"call……"

After Lu Yongchang swallowed the last bit of food in his mouth, he breathed a sigh of relief, and muttered to himself: "The task can be regarded as completed."

"Mission?" Mao Zhengzhi looked at Lu Yongchang suspiciously.

"Cough! Nothing!"

"You came at the right time. I can be sure that the technology tree of the Proxima civilization is absolutely crooked. Their biotechnology far surpasses other disciplines..."

While talking, Lu Yongchang quietly stuffed the bags in his hand into the special trash bin beside him.

……

Inside the biology lab.

Mao Zhengzhi silently looked at the holographic projection in front of him.

In the holographic projection, the familiar human gene sequence is on the left.

On the right is the genetic sequence of Proxima Centauri.

"The genes of Proxima Centauri are very different from ours. Among them, the biggest obstacle hindering us is their base pairing principle."

As Lu Yongchang spoke, he reached out and manipulated the holographic projection.

"According to their research data, I found some basic interlinkages between the genes of the two sides."

"Intercommunication?" Mao Zhengzhi was slightly taken aback.

"That's right." Lu Yongchang shrugged, "For example, they are creatures that perform aerobic respiration just like us."

"Through these basic genes, and with the help of the research data of the Proxima Centauri civilization, I found a corresponding rule for the genes on both sides."

"And the synthetic gene of telomerase can also be transformed through this corresponding rule."

As Lu Yongchang's voice fell, the complex gene in the holographic projection changed slightly.

Spin, disperse, recombine...

After a series of corresponding changes, a brand new gene sequence appeared in front of the two.

Different from the original one, this genetic sequence is a shape that Mao Zhengzhi is extremely familiar with.

"but."

Before Mao Zhengzhi was happy, Lu Yongchang's voice sounded again: "Because the genetic structure of Proxima Centauri is somewhat different from ours, there are many possibilities."

"At that time, we may have to make some attempts..."

Mao Zhengzhi breathed a sigh of relief: "Isn't it just luck and trial and error, what's the matter?"

"By the way, how many possibilities are there?"

"...About a hundred thousand kinds."

After the voice fell, the holographic projection instantly enlarged, and more than [-] gene sequences were all presented in front of Mao Zhengzhi's eyes.

Mao Zhengzhi: "..."

You call this something to try? !

He swallowed slightly: "I think this task may be a hundred million points of difficulty..."

……

Tucao returns to Tucao.

At this point in the experiment, there are millions of possibilities, and they have to bite the bullet and try their luck.

As for the experimental method...it's actually very simple.

Just insert these base pairs into the gene of Escherichia coli.

Then, it is to see if these E. coli can survive.

Only Escherichia coli that can survive normally can enter the next screening process.

Observe whether the inserted base pair is "working" normally-synthesizing that special telomerase-like enzyme.

……

The idea is good, but the reality is cruel.

More than two full months have passed.

They have only completed the first step of the experiment.

This is still done with the help of Zero.

Still, there is good news.

At least, the choices they face have shrunk by 99%.

Originally there were more than 1000 possibilities, but now there are only more than [-].

Lu Yongchang and Mao Zhengzhi had no time to take a breath, so they immersed themselves in the second step of the experiment.

Over time, sample after sample was eliminated.

In the end, what remained in front of them was the only possibility.

Lu Yongchang took a deep breath and said in a deep voice, "Let's start checking."

With slightly trembling hands, Mao Zhengzhi took out the sample, ready to start the inspection.

This is the last sample.

If they fail, it means that their time of more than two months has been wasted!

Chapter 299 Longevity Enzyme

The entire inspection procedure seemed to be engraved in the minds of the two of them.

After Mao Zhengzhi completed all the operations smoothly, he stood aside anxiously waiting for the test results.

There was silence in the laboratory.

Even Lu Yongchang looked at the holographic image in front of him with a troubled expression.

Time passed by minute by minute.

The projection interface suddenly changed.

【Telomerase has been detected】

"it is good!!"

Mao Zhengzhi whispered softly: "It finally succeeded!"

Lu Yongchang also heaved a sigh of relief, reaching out his hand to wipe the beads of sweat oozing from his forehead.

Unlike the telomerase-like substance in Proxima Centauri, the telomerase-like substance synthesized by Escherichia coli is a pure earth life substance.

Although they have the same function, their structure and composition are quite different.

"In order to distinguish, let's call it longevity enzyme in the future." Lu Yongchang looked at the sample in front of him, his face was full of expectations, "Next, as long as this enzyme can be verified to function in the living body, human beings can break through The lifespan of the race has reached its limit!"

Mao Zhengzhi was stunned: "How are you going to solve the problem of cancerous cells?"

Lu Yongchang chuckled: "Although we don't have the magical organs of Proxima, don't forget, we have medical cabins and nano-robots."

"At that time, as long as the medical cabin and nano-robots are used for regular body checkups, it will naturally kill cancer from the root just like Proxima Centauri."

Suddenly enlightened, Mao Zhengzhi tapped his head lightly with his hand, and laughed softly at himself: "Look at my brain..."

"It's really stupid to do experiments and forget such an important technology."

Lu Yongchang didn't care much.

Blind spots in thinking, everyone will have them.

"The next step is the biological experiment."

Hearing these words, Mao Zhengzhi's expression suddenly became stiff.

"Professor, have you forgotten something very important?"

"We don't have any organisms to experiment with right now."

Hearing this, Lu Yongchang was taken aback.

Soon, he reacted.

At the time of departure from Mars, all living organisms except humans existed in the form of germ cells or genetic samples.

Not only does this save space, but it also saves a lot of hassle.

Such as the huge overload during acceleration and deceleration, the necessary materials to maintain their lives...

Although they have a large number of germ cells of mice, they can reproduce them in this universe with the help of "test-tube baby" technology.

But that takes a lot of time.

At least, with the remaining lifespan of the councilor, it is impossible to wait for the results of this experiment.

Lu Yongchang's face suddenly turned ugly.

"professor?"

Mao Zhengzhi asked in a low voice: "How about I start to unfreeze the gene bank of the mice now?"

Lu Yongchang pondered for a moment, then nodded slowly: "The zero-gravity environment in space will have some impact on the growth and development of mice. Send a few Xuannv-[-] to the surface of Proxima b to cultivate them."

Mao Zhengzhi responded, and hurriedly turned and left.

Lu Yongchang looked at Mao Zhengzhi's back, and murmured in a low voice: "I hope...the chairman of the council can hold on for a while."

……

The earth calendar is 2148 years.

Just as the first batch of mice were about to "come out of the cage", a bad news came.

"Professor, the chairman's physical condition is rapidly deteriorating."
