After a long, long time, the whole world finally came out of the haze of radiation contamination and got back on track.

The people lived in an era when there was no fortress city, and they were very uncomfortable at first. The fortress city is a product of the Advent Era and has a history of more than two hundred years. This group of people all grew up and lived in the fortress city, and they completely took this inconvenience for granted.

But without the fortress city, everything is back to what it was before the Advent Era. They scavenged through historical sources and tried to reconstruct the way it was built. Wide roads were built between the cities, so that everyone could go out of the city and drive, and the outside world would no longer be full of dangers. Dart games have become dispensable.

Once people get acquainted with this kind of life, they immediately feel joy from the bottom of their hearts and can never go back to the past.

The whole world gradually returned to normal functioning, and industrial agriculture developed again.

After many years of multiplication, homes were reclaimed from the originally barren land, and settlements were scattered everywhere to form cities.

Streets, bazaars, shopping malls, schools...... Everything is back to what it was before the Advent Era. I don't know how many hundreds of years have passed, and the whole world has been metamorphosing again and again, and there is no trace of radiation at all in the metabolism of generation after generation.

Everything is thriving, and it is so prosperous that it has caught up with what it was before the beginning of the Advent Era. The deviation of hundreds of years in the middle has finally been smoothed out.

The scientific and technological achievements left by the previous generation of mankind have been tirelessly sorted out and translated by generations of scholars, and most of the useful technologies have been mastered by mankind. Their world is far more developed than the current human world, and new technologies are like a timely rain for the post-disaster world that needs to be developed urgently. The technology of the previous generation of humanity has made up for the time that humanity has wasted fighting the Advent for hundreds of years.

The two generations of human civilization are just connected with each other, and to a certain extent, it can be regarded as a kind of providence.

……

What was once an era of advent has become a piece of history.

The site where the laboratory was originally located is now a memorial. There are always people who offer flowers.

……

After a long time, in the memorial.

Today it is especially crowded because a new technology has been born.

This is the first time that humanity has learned from the experience of a previous civilization and put it into use. At the press conference, people from all walks of life and ordinary people came everywhere.

The red carpet covers the entire memorial hall, which completely imitates the appearance of the old laboratory, and the construction of a round arch building with glass and special metals, with a minimalist streamlined style, ensuring maximum earthquake resistance and durability, combining beauty and practicality to a clever degree. This is the crystallization of the wisdom of the previous generation of human civilization!

The red carpet weaves between large and small booths and beams, crowds of people, constantly moving between the exhibits and the picture frames hanging on the walls.

On this day, a circular stand was erected in the middle of the memorial hall, covered with a red cloth. Seats were all around, and the guests were crowded together, looking forward to the middle of the booth. Such a grand occasion is as vast as the day when the previous generation of humans invented the bionic prosthesis.

"How to make use of the achievements of human civilization in the previous generation and the gap between us over the years has always been a difficult problem that the whole world is focusing on."

On the podium, a young scholar in a white lab coat held a microphone in his hand and was impassioned. The ever-changing projection behind him changed the content of the picture with his words, projecting the ocean-like dreamy fluorescent blue holographic three-dimensional words in front of everyone's eyes.

"We've been through so much and now we need to stand on the shoulders of those who came before us and make the most of their legacy. In this way, it is not considered to be a disappointment to the predecessors. ”

"The wisdom of the previous generation of human civilization is close to it, and it is all condensed into digital information, in which the development of various sciences is far beyond that of us today. Therefore, how to use this condensed information has become the key to the technology that needs to be broken through. ”

"Learn from scratch bit by bit? What a waste of time. ”

The audience listened with bated breath.

"Ladies and gentlemen, the most exciting time is coming—"

The young scholar cleared his throat and pinched the frame of his glasses with his hand.

Bang!

A salute suddenly burst into the air, and colorful scraps of paper fell from the sky, falling like petals one after another, landing on the heads and shoulders of the crowd. Everyone was infected by this excited atmosphere and applauded in unison.

Swish!

The red cloth on the stage was suddenly torn off, revealing what was inside!

It was a delicately transparent instrument with a clump of cells floating in a blue crystalline liquid!

"The Advent are powerful because they mechanize human tissues and digitize their minds. Let consciousness become a little chip. There is much more that can be stored in the chip, far more than what a human can learn in a lifetime. Even if you spend your whole life learning with love, you can't achieve the effect of chips. Moreover, you have studied hard all your life, and it only takes a few tens of seconds to store it in the chip. And this is a completely painless process, and there will be absolutely no forgetting, mistakes, or omissions. ”

"If everybody can improve their knowledge in this way, then we can immediately multiply our level of development and reach a level of prosperity that we have never experienced before. We can save time for construction and enjoy life. I believe that soon, it will be possible to reach the level of the previous generation of human civilization. ”

The lights went out, and only the high platform shone brightly, and all eyes were on it. A faint blue light fell and rose and fell over everyone's face like a wave.

Whoa...... The audience burst into applause. The mood of the crowd couldn't help but get excited.

"We've experimented with all the knowledge being burned into these brain cell culture tissues. The effect of the current experiment is that they survive very steadily. The incoming content shows no signs of subsiding, and the time is at a normal rate of metabolism. ”

"From this set of experiments, it can be seen that there is no danger in the storage and transplantation of memories."

The researcher on stage continued.

"If this technology is open ......"

"I disagree with you!"

Suddenly, a man wearing glasses and a suit stood up from the audience with a serious expression.

"A successful trial does not mean it is clinically viable! And, even if successful, we all know that the reason why a person becomes himself and not others is determined by his conscious mind. When his consciousness is tampered with, is the person who has been tampered with still the original him? ”

"How can you guarantee that you won't tamper with other content without consent while entering knowledge again?"

When the man finished speaking, he caused a small shock. There was an uproar below, and the flash clicked.

"Of course, of ......course," the scholar on the stage gestured to silence everyone, "this is just an assumption, 10,000 steps back, if you really want to enter the clinical stage, there will be a complete implementation of relevant laws." And it's all voluntary. ”

"But anyway – there's a limit to how much we can grow. Unlike the Adventists, we will never follow the path of our predecessors. ”

"All development will not be at the cost of harming human beings, and all scientific and technological innovations applied to the human body will be voted on in an all-round way."

"The Descenders are countless times more developed than us, but because of their excessive greed, they finally embarked on the road of no return."

"We will never seek the eternity of life. When something is completely beyond the laws of natural development, it means the beginning of decline. No one can escape the real law. ”

"With the lessons of two very different civilizations, we will definitely go further."

"Today's launch meeting is just the beginning, and in the future, there will be more projects that everyone is looking forward to voting on......"

Bang Bang Bang Bang ...... The applause continued.

Next, the voting session began. Everyone got up one after another, and rushed to the booth like a tidal wave.

After a long time, the vote ended, and the majority of the people had reservations.

And so the show ended.

……

The crowd left one after another, and the entire venue gradually fell silent.

After the final interview, the lecturer returned to the lounge at the back of the pavilion wearily with his sample.

His colleagues asked, "What is the result?" ”

"It didn't work out," he sighed and shook his head, "but this was just the beginning of my research career." I am sure that I will definitely come up with a way to really put the crystallization of the previous generation of civilizations to use. ”

"It's not too early...... the other researchers packed up their things, loaded them into the car, and sent them back to the lab.

"I'll see if there's anything pulled down, and I'll be right away." He muttered, and returned to the pavilion alone.

At this point, the common room was empty, and the small glass bottle of his research result, soaked in blue liquid, was placed on the table.

Goo-dong, goo-dong.

Suddenly, there was a hurried but faint sound from inside.

The fine bubbles in the water are rising more and more densely, completely different from the previous monitoring data.

The surface of the clump of cells soaked in the crystal blue water began to tremble slightly.

Inside the cell, countless memories implanted in it suddenly come to life. It was as if there was no exit, and the writhing light suddenly found its way, and it instantly brightened, shuttling rapidly through the entire network pipeline. The corners of consciousness in the darkness are gradually illuminated.

"Consciousness" realizes itself at this moment, recalls the things that were tight, and becomes itself.

These memories come from a new ticket stored in the back of the brain of the android "Goddess Themis". Her thinking network is to connect the "round heaven and the place" together, so that they can circulate and back up each other for a while.

At the moment when Ren Yi blew up the "Black Goat" network and turned into ashes, the connection between the "round sky" and all the people on earth was broken. At that moment, all the memories in Ren Yi's mind had been backed up in the chip of the goddess Themis.

At this moment, the brain cells that stored the memories returned to the old laboratory, and the familiar Huaijin aroused the consciousness that had been sealed in the memory for a long time.

In retrospect, there is a lot of truth in the questioner's words – a person is who he is and not someone else because he has a unique soul of his own. Just like in the mechanized planet, each person is distinguished from each other by his unique consciousness.

When Ren Yi's memory and consciousness come to life at this moment, it is equivalent to his soul being reborn at this moment.

I don't know how long it took him, but he finally saw the reborn earth in the form of his mind.
