The extravagant outfit could barely hide the man's pale, thin face.

In his hand, he carefully held a small metal plate, on which lay a notebook that looked like it could be turned over, but was already half rotten.

This small book should have gone through a lot of hardships, and you can vaguely see the black marks of high temperature burning on the cover made of cowhide. The book is covered by a glass cover.,Showing that the owner is still very patient with it.。

This small book, which is only half left, is Su Zhe's research notes from more than 400 years ago.

At this moment, the "raven" held the plate in his hand and secretly glanced at the man named Su Zhe, his eyes were a little erratic, and he looked very overwhelmed.

Although Raven was already the king of Shacheng and was honored as "Your Highness" by his subordinates, in front of this person, he was like an obedient child, with low eyebrows and eyes, and he didn't even dare to make any small movements.

Although the two were about the same age, he knew that this person named Su Zhe was his ancestor more than 400 years ago, which was verified by genetic mapping.

It had only been a few hours before that he had accepted this fact, somewhat dumbfounded.

In the ancient base under the royal city, no matter which repaired smart lock device, as long as the man puts his finger on it, the woman in the projection will invariably smile professionally, and the iconic, clear and beautiful synthesized voice will be heard, saying a name - "Dr. Su".

The test results were no exception:

"100% match for target detection"

"100% SNP match"

"Total DNA match 100% ......"

“……”

As long as there are no errors in the program, all key detection items are 100% passed, and all authorization items are also the top and most complete. This also shows that Su Zhe is the identity of the real owner of this N544 base.

If this was not reliable evidence, then there was no better way to verify identity, and everyone present was dumbfounded, and Raven was so frightened that he couldn't say a word on the spot.

As the supreme authority researcher of the former civilization "Titan Project", everything in this base was imprinted in Su Zhe's mind, even the location of the equipment was untouched, as if he had left more than four hundred years ago.

In the past, the things that were difficult for them to explain, or even completely incomprehensible, were solved easily after Su Zhe arrived, and even without much effort.

In front of him, instruments, devices, brain records, and incomprehensible data are not a problem, everything is open for him.

Although Joyna was in the Ancient Iron City, she also took the time to explain the situation to the raven and the others in her busy schedule, and also explained the reason why this person named Su Zhe had to come to Shacheng.

Although there is a distance of dozens of kilometers between the ancient iron city and the sand city, with the help of the powerful brain of Dongfang Road and the many flying machines left behind by the Faceless Emperor, it is still guaranteed to transport materials and communicate with each other.

Hearing the voice behind him, Su Zhe was slightly stunned for a moment, then looked at the raven, the king of Sand City, and smiled awkwardly.

He quickly took the small metal plate with one hand and stared at it. The whole person seemed to be petrified, and after more than ten seconds, he shook his head, and a slightly disappointed look appeared on his face.

But this imperceptible look of loss is only fleeting.

This notebook, which records his research experience of the "Titan Project", is worth something that cannot be measured by all the money in the world.

Although anyone who wanted to get it back then could line up from the palace to the gate of the street, countless private research institutes and commercial spies around the world took great pains to get a glimpse of what was inside. But now, the only thing that means to him is the feelings in the memory of the dust, and it has no practical value.

In those years, in the experimental base of the Jidu people, Su Zhe had seen enough and shocked enough research. Although it took him many years of experience to write down the things recorded in this notebook, it seems that now they are all superficial and superficial things.

He won't look at what was written down in this notebook anymore, everything has changed. Now, even his own body is enough for him to study for a lifetime.

"Hey, take it...... Maybe it's better to keep it in a museum, or you can keep it for yourself. ”

After saying this, Su Zhe's heart seemed to be a little touched, and he smiled awkwardly at the raven, in fact, he also knew that in this era, it was impossible for a museum or something to exist.

Raven looked at Su Zhe's calm expression, hesitated for a moment, and nodded, "Okay, as you wish." ”

In fact, it was not only the raven, but Su Zhe was also embarrassed.

Looking at his descendants four hundred years later, his heart fluctuated, and he really didn't know what kind of expression to use to face it.

He was almost sixty years old before he was put into that container.

Four hundred years later, he looks like a middle-aged man who resembles a raven, and if you count the hibernation time, the difference between the two is more than 470 years.

As we all know, the royal family of Shacheng is surnamed Su, and they are all descendants of his Su Zhe, all of which makes Su Zhe feel very emotional—no one has ever had the same experience as him.

It was hard to describe in words, and even he was shocked.

After chatting with the raven for just ten minutes, he knew something, there were many rules in the royal family of Shacheng that made him feel like he was in a different world, but after really understanding it, there were some things that made him laugh.

Back then, he did set up the password of the brain and added his own unique and little bad taste.

The image of the woman in the projection was modeled after his daughter, and it was also one of his little secrets.

In addition, in his original data storage room, Su Zhe had set up a password that no one could understand, and only people who correctly drew a simple symbol on the light screen could access those confidential information.

The symbol is called "Yi'o", and you can outline it with your fingers with a few simple strokes.

And its significance, only Su Zhe himself knows, comes from a book he has read, which is about the myths and legends of ancient Greece.

Io - is a beautiful and moving girl, but was taken by the **** Jupiter, although Io deliberately avoided him, or was turned into a cloud by Jupiter and the girl......

And the meaning of the name Io has two meanings.

The first layer of meaning is superficial, Io represents the moon of a gas giant in the solar system, Jupiter's Europa.

This asteroid is where he first worked in space, and in pre-civilizational times, the "Planetary Council" set up a deep space base in the orbit of Europa and Jupiter for the "Titan Project", and Su Zhe lived on it for a while.

The other meaning is more subtle and symbolic.

His daughter's name is Su Qingyu, who has seen images of Europa when she was very young and is fascinated by it. Every time she saw the projection of the asteroid, she had to pester her father to tell the story of that Greek mythology, and she liked the name "Io" very much.

"Dr. Su, I have some questions I want to ask you......" The raven's voice recalled Su Zhe's consciousness.

Su Zhe nodded at him, "Well, please speak." ”

"Actually, I wanted to ask about the anti-gravity engine under Sand City......"

"You mean the M-particle device? What's wrong with it? ”

"Ah no, it's fine, nothing special. I don't know what to say, I've just never been exposed to such an incomprehensible level of technology...... We're floating in the air at a height of 10,000 meters, this ...... It's just a little worried. ”

"Worried?"

"Well, yes. Although we have repaired most of the mechanism, and it is now working very well, its power core material should be irreplaceable, and we can't have a spare one, if it is ......"

Hearing this, Su Zhe couldn't help but smile indifferently, "Heh, needless to say, I understand what you mean, you are so worried...... Well, that's normal. ”

He understands that it is the other party's fear that is at fault.

This kind of landlubber swims for fear of being choked to death by the water, although there is no reason, but in Shacheng, it is indeed a psychological burden for most people.

Living in this wild and violent era, let alone experiencing it firsthand, just seeing this kind of technology that surpasses hundreds of years today will make people seem overwhelmed.

The unknown is indeed frightening.

Moreover, even in pre-civilization times, this kind of thing was difficult for ordinary people to understand. Just like taking a plane for the first time, almost everyone will be afraid at this altitude of 10,000 meters.

"Put your heart in your stomach, you don't have to worry about this at all."

Su Zhe's face was pale, the sarcoma on his forehead was bulging, and the "True Pupil" slowly opened.

"Oh, I know, you're afraid it's going to fall, right? You're right, it's true that those things can't be made on Earth, but it's almost permanent, and you don't have to worry about what will go wrong. ”

Su Zhe said very calmly, "The isotopes of M particles, mainly hydrogen and its isotopes, contain huge energy, which is a metal-like superconductor formed by hydrogen after millions of atmospheres of pressure, and is a by-product of metallic hydrogen, and it is processed by several special radioactive elements. Theoretically, it has a half-life of 700,000 years, that is, it can maintain a lifespan of at least 700,000 years. So, rest assured, there won't be any problems. ”

Su Zhe blinked mysteriously, "So, don't talk about you and me, I'm afraid that at that time, this earth will be gone long ago!" ”

After listening to Su Zhe's understatement, the raven nodded incessantly, and made a hmm-huh sound from his mouth from time to time, as if he really understood.

In fact, except for the last sentence, the other ravens didn't understand it at all, but they didn't know it, and they admired their ancestors surnamed Su even more.

"In short, it's good to put your heart in your stomach, it's a matter of no reason."

Watching the raven leave with a look of humility and reverence, Su Zhe also breathed a long sigh of relief.

At this time, his heart was missing someone.
