Interstellar Immortality: Live long enough to dominate the universe

Ella's speed has always been different from what Yan Xia understands.

But this time, Yan Xia didn't have to wait too long.

When Yan Xia woke up from hibernation again, he was a little dazed to see the time, because only 5 years had passed.

"Are you sure it's finished?"

The units in the previous decades were very small.

Ella wore a white coat and pushed the gold-rimmed glasses on her nose.

"Of course."

"I have learned all the information on the Internet in the Earth era, but I just lack practice in the field of biology."

"I have used 1,838 samples of the Hundred Eyes for research. Although this number is not large, the information collected is enough."

"The improved Ankh-25 agent will be used as the main gene modification drug, and other means will be needed to assist. After 12 courses of treatment, the most basic hematopoietic stem cells of the human body will be changed, and the human body will be able to make new cells by itself, completing the whole body's genetic blood replacement."

Ankh means life in ancient Egypt on Earth.

This is what ancient humans yearned for.

It is also what we want to achieve now.

A name seems to connect the past and the present together.

However, Yan Xia noticed a piece of information.

Whole-body gene replacement.

He knew that even a slight change in genes could create another species.

For example, on Earth, the genetic similarity between mice and humans is more than 95%, and humans and a random tree on the street have more than 40% genetic similarity.

Even a difference of one thousandth or one ten-thousandth of a gene can form reproductive isolation.

If he forms reproductive isolation with ordinary humans, then is he still a human?

He had actually thought about this idea a long time ago, even when he was on Earth.

It's just that he had never thought deeply about it.

Because genetic modification or genetic programming was an unattainable thing for all humans of that era.

And now that the matter is in front of him, he actually already has the answer in his heart.

Now he is the only human being, and human civilization should be continued by him, and he should not hold conservative ideas.

Of course, he can't hold it at all.

"Then is there any other way to preserve human genes?"

"When biotechnology develops to the top, it should be possible to cultivate complete embryos with human cells, right?"

Ella nodded.

"That's right."

"In fact, the Earth has been continuously advancing this technology since 2010, and similar experiments have been completed in 2023."

"By 2037, this research has reached the maturity of the experimental mouse stage."

"If you want to use human cells to cultivate humans, then I can do it now."

As a person who doesn't know much about biotechnology, Yan Xia didn't expect that this method would be easier to achieve than he thought when he heard this.

"In other words, I can now completely reproduce humans?"

Ella explained.

"In fact, Yan Xia, you can think of this technology as a cloning technology."

"Since the birth of Dolly the cloned sheep in 1996, cloning technology has been advancing."

"Although this is a taboo in human relations, if you have ever kept a pet, you should know that cloning technology is widely used in the field of pets."

"For example, if a person's pet dies, then he can clone the pet in the hospital and get an almost identical pet, and it only costs a few hundred thousand."

"And reproducing humans is of course more difficult than cloning, and ordinary cells need to be cultivated into sperm and eggs."

"But the difficulty of this technology itself is extremely limited, because all cells in a person are initially formed by the combination and division of sperm and eggs, and they do not have any biological specialities."

In short.

It is very easy.

Yan Xia took a deep breath.

"Then leave some human genes to reproduce humans later."

Not long after he finished speaking, the door of the cab was opened, and a naked person walked in from outside?

"What is this?"

Yan Xia frowned when he saw the thing.

"To reproduce humans, sperm and eggs need to be cultivated from cells."

"Since you have one of them, Yan Xia, why don't you take it directly?"

"This is a silicone robot I made specifically for you. It can help you collect."

"This is also to restore the human race."

Ella was very serious, as if this was an important task.

But Yan Xia refused directly.

"Forget it, I will collect it myself later."

Although the robot was almost indistinguishable from ordinary humans, he was still not used to it.

After saying this, Yan Xia actually felt that Ella's virtual paper man had a trace of regret on his face.

I don't know if it was his own illusion.

The most critical point is that this robot should not be produced so quickly, it can only be prepared in advance.

"Okay, Yan Xia."

"Please complete the collection quickly."

"Your genetic modification surgery is ready. Each course of treatment is 1 month, and 12 courses of treatment are exactly one year."

"During this period, you cannot sleep or move, you can only lie in bed."

"But don't worry, I have automatically generated a lot of novels and movies for you. The only regret is that you can no longer eat delicious food, but instead use nutrient solution."

This is simply torture for Yan Xia.

The taste of nutrient solution is so good that even if it is made into juice or cola, you will want to vomit if you drink too much.

But between life span and not being able to eat for a year, Yan Xia still chose the former.

After he made the preparations that Ella had said before, he went to the test area of ​​the Hope.

He has not even been here a few times.

Unlike the other areas with rich colors and light and dark lights, the word "white" is the first word here.

The light is white, the walls are white, the floor is white, and even the robots that come and go here are white.

It is so white that a little dust entering here will look unusually abrupt.

Through the glass, Yan Xia saw his operating table.

It is very huge.

There are more than 20 mechanical arms hanging above the operating table, which are in charge of various medical devices and look a bit hideous and terrifying.

"Don't worry Yan Xia, these robots have been tested with thousands of Hundred Eyes to ensure absolute accuracy."

Ella's holographic projection has been leading the way in front of Yan Xia.

It bounced and looked very happy.

But Yan Xia couldn't be happy.

Humans seem to be afraid of surgery from the depths of their genes.

But he is not a hypocritical person who hesitates for a long time before doing things.

He also put on a white suit under Ella's arrangement, and then lay on the operating table.

When a needle pierced his artery, his consciousness gradually became blurred.
