In the not - so - wide stairwell, Yu Yifeng moved at full speed. His figure shuttled like a ghost, climbing, jumping, and dashing. He could cover one floor in just two or three steps and leap to the height of one floor. His powerful physical fitness, extremely high environmental adaptability, and flexible movements far beyond those of ordinary people made it no exaggeration to call him a "superhuman"!

In fact, he had kept something from his team members: a long time ago, there had already been a successful case of transformation by the Perfect Element, and that case was their captain - Yu Yifeng!

This story was rather long. It wasn't that he deliberately concealed it, but that his superiors had required him to keep it strictly confidential.

More than twenty years ago, after the Lunar Base took initial shape, the human government couldn't wait to carry out relevant experiments.

The Perfect Element was a non - renewable substance. Although there was a relatively large quantity, it was still limited. Therefore, it couldn't be wasted on animals on a large scale. So, the first batch of experimental subjects was human fertilized eggs.

Because fertilized eggs have the same genes as humans but are not really human beings in the true sense, using them for experiments could reduce some moral and ethical risks. After all, many scientists still had professional ethics, and few people were willing to conduct real human experiments.

Animal cells are much more complex than plant cells. Especially humans, as the only intelligent beings on Earth, have 46 chromosomes and more than 39,000 genes. The mechanism of action of the Perfect Element is even more complicated. With the current human technological means, it is simply impossible to peek into its mysteries, and we can only explore and study it through large - scale experiments.

In the first experiment, governments of various countries selected about 100,000 fertilized eggs from the human gene pool. Unfortunately, due to various reasons, the first batch of experiments all failed. At that time, the Lunar Base was not yet complete, and all technical indicators were not up to standard. The mortality rate of fertilized eggs was extremely high.

However, there were also a very small number of successful cases. Strangely, after these fertilized eggs were transformed by the Perfect Element, they turned into mature human cells!

They lost the totipotency of fertilized eggs and could no longer divide or differentiate. These cells had extremely strong metabolic capabilities, long lifespans, and all indicators far exceeded those of normal people. However, after these cells were transplanted into the mother's body, they still couldn't divide. These non - dividing fertilized eggs naturally couldn't grow into humans. No matter how powerful they were, they were just cells, and the experiment ultimately failed.

But the human government didn't give up. Instead, they saw hope in this. Subsequently, they mobilized even greater strength and carried out a second experiment. This time, they collected millions of fertilized eggs!

Leaving the process aside for now. Two years later, a miracle occurred - Yu Yifeng was born! He was the first human to be successfully transformed by the Perfect Element...

Along the way, Calvin's voice came from the nearby broadcast from time to time. It was unclear whether he was speaking to Yu Yifeng or just talking to himself.

"Yu Yifeng, the lucky one who stood out from millions of fertilized eggs, the only successful case of humans so far, a miracle that is almost impossible to replicate. His cell metabolic capacity is three times that of ordinary people, his nerve reaction speed is ten times that of ordinary people, and his life cycle is as long as twenty times that of ordinary people. That is to say, Captain Yu Yifeng's normal lifespan is over 1,500 years old... This astonishing case shows that the Perfect Element is effective for humans!

This is a gift from God, a sign of God's favor towards him, but it has triggered the greatest greed in the human world!" His tone was filled with sighs, emotions, or anger.

"Everyone wants to become a superhuman, everyone desires a 20 - fold lifespan! Especially those rulers who are on the verge of death. They already occupy a large amount of social resources, but they are still not satisfied and want to live longer..."

"However, the Perfect Element is limited and non - renewable. This means that only one in a thousand people is eligible to become... a superhuman!"

Yu Yifeng couldn't refute. He knew this information but had never thought deeply about it. This problem was too complex. Most of the world's resources have always been concentrated in the hands of a few people, and this has been the case in every era. But this time, the Perfect Element was different from money, oil, etc. It was something that could completely change a person's life...

He quickened his pace and climbed to the top floor in less than two minutes.

Calvin was standing in a glass room. He was a tall Westerner in his forties, his face flushed red, and his emotions were extremely agitated. "Everyone is equal. Why do they want to control everything? Why? Why?"

He shouted loudly, took out a controller from his pocket, and roared, "Yu Yifeng, tell me, who is the one in a thousand? Who is eligible to be the one in a thousand?"

"Is that... a remote control?" A sense of extreme unease welled up in Yu Yifeng's heart. He secretly groaned. He had dealt with Calvin before and knew that this person was extremely paranoid and very difficult to communicate with. If he accidentally provoked him to detonate the bomb, then everyone in the entire building would be doomed!

The room where Calvin was located was made of special glass. Bullets couldn't break it, and it was impossible to break in directly.

Helplessly, Yu Yifeng had to try to ease the other person's emotions first. "At present, there has been no breakthrough in the application of the Perfect Element. The success rate of transforming adults is zero! So, there is no need to consider this issue for the time being!"

"No, you don't understand!" Calvin shook his head, pointed in the direction of the Earth, and shouted, "God has made a choice for us! Those who are unworthy of the Perfect Element have been completely destroyed... Now, we humans are about to enter a new era!"

"Come on, Yu Yifeng, the first superhuman, the first person to be transformed by the Perfect Element. Let me see your true strength!" As he spoke, Calvin suddenly opened the glass door.

"As long as you can catch me within five minutes, I'll give you this remote control!"

Then, he quickly ran out of the door.

"Five minutes, only five minutes!"

Although he didn't know exactly what Calvin was going to do, Yu Yifeng immediately rushed over and followed closely behind.

This was a metal passageway about a hundred meters long. There were corridors leading in all directions around it, which was extremely complex. Calvin had lived on the Moon for five years and was already accustomed to the environment here. Judging from his body shape, he should exercise regularly, and he ran very fast.

Yu Yifeng didn't dare to shoot rashly, for fear that if he did, Calvin would directly detonate the bomb. He chased after him quickly.

"My 100 - meter speed on Earth is about eight seconds, far exceeding the world record. I can run even faster on the Moon. Catching Calvin shouldn't be a problem!"

In just a few seconds, the distance between the two of them was shortened a bit.

Suddenly, two iron balls appeared on one side of the corridor. Each was as big as a basketball. At the front of the balls, there were two electronic eyes similar to real eyes, which could rotate 360 degrees freely. Around the balls, there were eight metal legs as thick as chopsticks, just like spiders.

When these two balls saw Yu Yifeng, their electronic eyes immediately glowed red.

"These are... spider robots!"
