Ella's understanding had always been different from Yan Xia's, but this time she didn't make him wait too long.
When Yan Xia woke up from hibernation, he felt a bit disoriented because only five years had passed.
"Is it confirmed that it has been completed?" he asked.
The units had been very small in the previous decades.
Ella, dressed in a white lab coat, adjusted the wire-framed glasses on her nose.
"Of course," she replied.
"As someone who has studied all the information available on the internet during the Earth era, I only lacked practical experience in the field of biology."
"I have conducted research using 1838 samples from the Centocephalus species. Although the sample size is not large, the collected information is sufficient."
"The modified Anka-25 serum will serve as the primary genetic enhancement drug, along with other complementary methods.
After 12 courses, it will alter the human body's fundamental hematopoietic stem cells, allowing the body to generate new cells and achieve a complete genetic blood replacement."
Anka, in ancient Egypt on Earth, symbolized life—a concept long sought after by ancient humans, now on the verge of realization. It seemed like a name that connected the past and the present.
However, Yan Xia noticed a piece of information: complete genetic replacement throughout the body.
He knew that even minor changes in genes could give rise to another species.
For instance, on Earth, the genetic similarity between mice and humans exceeded 95%, and humans shared over 40% of their genes with any random tree on the street.
Even a minuscule difference in genes could result in reproductive isolation. If he formed reproductive isolation with ordinary humans, would he still be considered human?
He had pondered this idea long ago, even during his time on Earth.
However, back then, he hadn't delved deeply into it because genetic modification or programming was an unattainable concept for all humans of that era.
Now, with the situation right in front of him, he already had an answer in his heart. He was the only human left, and the continuation of human civilization should be in his hands.
He shouldn't cling to conservative thinking entirely, but of course, he couldn't abandon it completely either.
"Are there any other ways to preserve human genes?" he asked.
"When biotechnology reaches its pinnacle, shouldn't it be possible to cultivate complete embryos from human cells?" he suggested.
Ella nodded. "Exactly. In fact, Earth had been advancing this technology since 2010, and by 2023, similar experiments had already been completed.
By 2037, this research had approached the stage of testing on mice. If we want to cultivate humans from human cells, I can do it now."
Yan Xia, as someone who didn't have much knowledge of biotechnology, was surprised to hear this. He hadn't expected this method to be easier to achieve than he had imagined.
"So, you're saying that I can completely reproduce humans now?" he asked.
Ella explained, "Actually, Yan Xia, you can think of this technology as a cloning technique.
Since the birth of Dolly the cloned sheep in 1996, cloning technology has been advancing continuously.
Although it is taboo in terms of ethics, if you have ever had a pet, you should know that cloning technology is widely used in the field of pets.
For example, if someone's beloved pet dies, they can have it cloned in a hospital and get an almost identical pet at the cost of a few hundred thousand.
However, reproducing humans is, of course, more difficult than cloning, as it requires culturing ordinary cells into sperm and eggs.
But the difficulty of this technology itself is quite limited since all the cells in a person's body originally resulted from the splitting of sperm and eggs, without any special biological properties."
In short, it is very easy.
Yan Xia took a deep breath. "Then let's preserve some human genes for the purpose of reproducing humans later."
Not long after he finished speaking, the door of the cockpit opened, and a naked person walked in from outside?
"What is this?" Yan Xia furrowed his brows as he saw the object.
"To recreate humanity, we need to cultivate sperm and eggs from cells," Ella explained.
"Since you, Yan Xia, possess one of them, why not take it directly?"
"This is a silicone robot specifically designed for you. It can assist you in collecting them," Ella continued.
"This is also for the purpose of restoring the human race."
Ella appeared very serious, as if this was a significant task. However, Yan Xia straightforwardly refused.
"Never mind, I will collect them myself later."
Although the robot hardly differed from an ordinary human, he still felt uncomfortable with the idea.
After speaking those words, Yan Xia suddenly sensed a subtle trace of regret on Ella's virtual paper-like face. He wasn't sure if it was just his imagination.
The crucial point was that the production of such a robot couldn't have been so fast; it must have been prepared in advance.
"Alright then, Yan Xia."
"Please make sure to complete the collection quickly."
"Your genetic modification surgery is ready. Each treatment will take one month, and with 12 treatments, it will complete within a year."
"During this period, you cannot sleep, move, or do anything other than lying on the bed."
"But don't worry, I have automatically generated a large number of novels and movies for you. The only regret is that you can no longer eat delicious food; instead, you will be fed with nutrient fluid."
For Yan Xia, this was nothing short of torture. Even if the nutrient fluid was made to taste like juice or cola, drinking it excessively would still make him feel nauseous.
However, when it came to lifespan and not being able to eat for a year, Yan Xia chose the former.
After completing the preparations Ella mentioned, he headed to the experimental area of the Hope, a place he had rarely visited.
Unlike other areas with rich colors and varying light, as soon as he entered here, everything was "white."
Pure white walls, white floors, even the robots moving back and forth here were white.
It was so white that even a speck of dust would appear strikingly out of place.
Through the glass, Yan Xia saw his own operating table.
It was enormous.
More than twenty mechanical arms hung above the table, each holding various medical instruments, giving them a somewhat sinister and terrifying appearance.
"Don't worry, Yan Xia. These robots have already undergone experiments with thousands of the Hundred-Eye Clan, ensuring absolute precision," Ella's holographic projection guided Yan Xia ahead.
It bounced around in a cheerful manner, but Yan Xia couldn't feel any joy.s seemed to fear surgery deep within their genes.
However, he wasn't a person who would hesitate and procrastinate on things.
Following Ella's arrangement, he also put on a white gown and lay down on the operating table.
As a needle pierced his artery, his consciousness gradually grew blurry.
