Eternal life is the highest desire of almost all life.

Because eternal life itself represents an almost infinite amount of time, he can do almost everything, find almost all meanings—as long as he has a goal, he will not feel that eternal life is a bad thing, because it is the empirical proof of all meanings, the collection of all desires and dreams.

In the Terra Continent, where even the life span of an Ascension is quite short, there are few people who can not yearn for eternal life.

The stronger the person, the more the person who holds wealth, the more he has everything and wants to have everything forever, the more he can't help but crave it.

Don't thirst, chase eternal life.

But......

Now Ian, but he just wants to laugh.

"The law of eternal life?"

His face was very strange, like the kind of expression that wanted to laugh but felt disgusting, and there was a mixture of sympathy and disgust - probably like seeing a young man deliberately run a red light in order to shoot a short video, only to be run over by a large truck and need to use a shovel to shovel garbage.

He was like that, wanting to laugh, feeling sad, feeling contempt, but feeling pity for him and his family from the bottom of his heart.

The white-haired boy repeated with mixed feelings: "That's it? Do you call this eternal life? ”

"yes."

As if infected by Ian's emotions, Patrick turned expressionless after a sigh.

He closed his eyes, and after a while, sneered, "They think this is eternal life." ”

Ian was speechless for a moment.

Learning machines, which can instill knowledge through the subconscious, are based on the technology of the Terra people's 'signal bones', which can directly connect to electronic devices, and must be equipped with a brain that is adapted to the transmission of data-based information...... The structure of the Terra's brain was apparently modified to fit their electronic creations.

The learning machine can not only allow people to learn professional knowledge, but also can learn 'aesthetics' and 'etiquette' - except for the thinking mode that cannot be learned, it can basically learn almost all knowledge.

It can even help people who have lost some of their memories to 'learn' their memories from the past!

At that time, there was such a thing as a 'memory and knowledge bank' on the earth, after all, the thinking mode also has an adaptation rate, and the higher the adaptation rate, the higher the efficiency and stability of learning, and it is easier to master it thoroughly.

So, here's the problem.

If a person whose brain is blank and who does not have the slightest idea of self-thinking, he learns the 'memory' of another person.

Can it be said that the learner and the learner are the same person?

Is it possible for the learner to achieve 'eternal life' in this way?

The answer is obviously, no.

Not to mention that learning is only memory, the brain structure is different, the neural structure is also different, even if a blank person, learning a person's memory, will not see themselves as the 'learned' - there may be identity disorders, but the learner and the learner may not necessarily produce the same 'choice'.

This is obviously just another person with the same memory, let alone eternal life, and even having the same goal, let alone giving up or something.

At most, it can only be regarded as 'reverberation'.

But......

"It's not a dead path."

Although he looked down on it very much, Ian was already alarmed in his heart: "The learning machine is only the most basic indoctrination of 'memory' and 'knowledge' - however, if the 'cyber-oriented' consciousness uploader rewrites its input and output logic, it can achieve 'consciousness replication' and 'thinking algorithm replication'!" ”

"A blank body, through the reproduction of consciousness and thinking algorithms, through some kind of surgery and drug catalysis, to reset its neural structure, that can basically be regarded as the 'second self in the world'!"

"And this can already be regarded as an 'echo'!"

Echoes are completely consistent with the logic of ontology's thinking, they will make exactly the same judgment when they encounter the same thing, and they will only make different choices because of differences in intelligence.

If all the conditions are met, such as an identical neural network, and then the consciousness algorithm is accepted, the memory is instilled, and the nervous system is reconstructed, it is indeed possible to resurrect one person's will and mind in another.

Even, like an echo, you can make as many as you want.

At this point, it can basically be said to be 'immortal'...... For those who don't care much about self-identity, but just want to complete their 'goals' and 'dreams', and it doesn't matter which one they are, there is an 'other me' that is exactly the same as themselves, can make the same choices, and will never betray themselves, and can live in place of them and complete their goals.

What's the difference between that and living on your own?

But here's the problem.

"There's no way they're going to just accept the 'Echo' level."

Ian tilted his head slightly, looking behind him, in the direction where Isengard had left, and he said solemnly: "How can these sublimators with great strength and authority accept everything from another 'weak self'? ”

"What they need is not an echo, but a 'mirror'!"

- What they need is not a reproduction of consciousness, but a 'complete transfer of consciousness'!

——Upload your own thoughts to another person's brain completely, and then achieve the result equivalent of 'taking away'!

"You're so smart?"

This time, Patrick was really surprised, the blonde aristocrat originally thought that he needed to roughly explain the difference between echo and mirror, but he didn't expect that Ian could understand the difference between the two so easily.

But it's better that way.

So he shook his head with a smile and said, "Of course, what the 'mirror' needs is not only pure thought transmission, but also 'soul transfer'...... After the third energy level 'Heart Light' level, the body and soul are entangled and bound to each other, and even the fifth energy level cannot separate the intact spirit from their body when their body is intact. ”

"Although theoretically there is no essential technical difference between the mirror and the echo, it adds a lot of difficulty because of the existence of the soul."

Truly.

Ian thought thoughtfully...... Consciousness copying is not fundamentally different from mind algorithm copying, and consciousness uploading and downloading, but because this is the continent of Terra, a world with the self-proof of 'soul'.

Therefore, the difficulty of uploading consciousness is far greater than that of the earth.

Earthlings have no soul, and the only things that can prove that they are themselves are thinking algorithms and memories, and after uploading, they are equivalent to transferring themselves.

But not in Terra - in addition to memories and algorithms, souls have to be transferred!

Reverberations, echoes and mirrors.

mere memory; memory and algorithms; Memory, algorithms, and souls.

Indeed, this is a path to eternal life through the constant transfer of self.

The only flaw may be that even if all the souls of the memory algorithm are transferred, the original sublimated power cannot be left to the new body.

But it's not insoluble.

The boy now fully understands why it is Isengard - he has the blood of the royal family, and he has the blood of the 'Eclipse Light Refining Dragon'...... If nothing else, the purpose of that Axel, the defender of the land, should be to occupy Isengard's body, and then use the transformed eclipse to refine the dragon's blood, and in turn 'devour' or 'symbiosis' his past body!

In this way, he didn't even need to practice again, he could directly have the strength of the fifth energy level again...... The next thing to do is nothing more than to gradually cut off the bloodline and decaying body of the Eclipse Light Refining Dragon, and when he 'cuts off the old self', he will be equivalent to living out the second life!

And in the process, he can even control all the wealth and power that has annexed the entire Eren family by the way, so that the power of the royal family will be further enhanced!

- A real flower to play!

Ian isn't sure that this is Axel's full plan, but based on current intelligence, this is probably the purpose of the defender, and the logic is self-consistent, and it can also explain Patrick's actions.

As an experimental material and a future transfer target, Isengard must have at least the strength of the fourth energy level before he can try to possess the 'Emperor's corpse' of the fifth energy level, otherwise, he will either either recultivate, or he will have to erode the light refining dragon bloodline.

"Really...... Evil. ”

At this moment, even Ian, who didn't care much about these things, couldn't help but understand why Inaga II ...... He would denounce his family ancestors as 'extremely evil'.

In particular, the ancestors who acquired this technology may have used it in private, and even been eroded by the 'Ancient Echoes' that remained in the machinery of the pre-era civilization.

Ian didn't plan to figure out who was right and who was wrong between Inaga II and his ancestors, and they were all dead anyway.

As for now, he completely understood why the people of the Sequoia base would rebuke the Great Elder as a demon.

Because, whether it is an aftersound, an echo or a mirror, it needs to be made of human material.

In the absence of human cloning, this usually means erasing one's mind and preserving one's body as a vehicle for another life.

This is much more immoral than mere destruction.

Most of the doubts have been answered, and now Ian, there is almost only one question left.

"What about you?"

Raising his head and meeting Patrick's eye, Ian narrowed his eyes to hide the silver-cyan glow in his gaze, "Why didn't you tell Isengard about this?" ”

Patrick...... What exactly is your purpose? ”
