It's not impossible.

Ian had already learned from the murals that the ancestors of the Redwood natives used a number of methods to make future generations remember the knowledge they needed.

The most stable and best learning machine was eliminated because of difficult maintenance and excessive energy consumption, and finally this laboratory with an alien xenobiosphere chose to use a biological plug-in to carry those necessary memories, and at the same time transform itself, and put some of the most critical knowledge and thinking steel seals into the DNA of future generations.

Ian knew that the Terrans were a stable race with extremely stable DNA and would not mutate abnormally due to the reproduction of offspring, which had the advantage of keeping them stable and unmutated even in various extreme situations...... With the biological alchemy of the Terra, there is no harm.

However, without biological alchemy, the most disadvantage is distortion, and it is difficult to adapt to some extremely abnormal special environments through mutation.

However, the Terrans are inherently adaptable to all environments, and this disadvantage is really non-existent.

In the same way, if the knowledge is written in the creature plug-ins of Terra technology or even in their own bodies, it is indeed a more stable method of transmission than anything else.

However......

All technology does not go wrong, and the premise is that people do not have problems.

A certain generation of Sequoia Great Elders had a different mind.

He wants eternal life.

"Is it to modify the auxiliary thinking organs, so that your own memories cover those who have the thinking organs installed?"

Ian immediately thought of this possibility.

Quite possibly.

Of course, as a Great Elder who had inherited the technology of the civilization of the previous era, compared to the Great Shaman who had deteriorated many times, he must be very aware of the difference between the reverberation, the echo and the mirror.

It's just the aftermath of memory, and it's not immortal at all.

And even the modified parasite, with its own neural network and thinking algorithm, is nothing more than an echo.

There is still a long way to go from the mirror method of true immortality.

But here's the problem......

"There is psionic energy in this world - if the speculation of this auxiliary memory plug-in is true, its quick link and knowledge transmission are probably also a kind of psychic energy for thinking sharing."

Crushing the brain of the Brain Eater in his hand, and carefully observing some traces of psionic energy left in it, Ian didn't feel disgusted, but just full of interest: "Could it be that the Great Elder has integrated himself into the Brain Eater's psionic network, and only needs to constantly update the host of the Brain Eater to ensure that his thoughts are always circulating?" ”

"And the reason why Master Gosai showed abnormalities before was that he came into contact with the knowledge stored in the Brain Eater's psionic network, or the memories of some of the Great Elders?"

Thinking about these possibilities, Ian somewhat understood why the redwood natives had left the redwood base back then.

A certain Great Elder, who had mastered almost all the keys, used other clansmen as flesh and blood tools to replicate his own consciousness for the sake of immortality, causing the other Sequoia people to revolt - the battle between the two sides led to the destruction of quite a lot of ecological tools, and all kinds of magical beasts and creatures that were still in the biosphere left the biosphere, deteriorating the originally stable situation of the base.

- Although I don't know the specific time, the fourth-level Frost Crystal Dragon and the Frost Butterfly can fight in the cooling warehouse, and the chaos back then is definitely dozens of times more intense than now.

The Great Elder must have failed, as evidenced by the fact that the four keys were kept by the natives, but due to the destruction of the ecosphere, they still had to leave the 'Holy Land'.

"That Great Elder may not be completely dead—just like the Great Shaman, the death of the crocodile may be a way for him to shed his golden cicada's shell, and there may not be no backhand left behind by the redwood natives."

"Of course, the crocodile is dead, even if the great shaman is really alive, it doesn't mean anything, not to mention that he definitely doesn't have such a high technology, at most he can back up a memory."

After washing his hands with river water, Ian stood up and looked around, thinking: "As for the redwoods back then, they should have wanted to destroy all the braineaters, but obviously, they didn't do this and hurriedly evacuated the base - look at the current situation, the braineaters are alive and well, at most they are not very conscious, and some are a little confused." ”

Synthesizing on various intelligence, he had a rough guess about what happened in the Sequoia base in the past, and Ian couldn't help but sigh a little: "Fortunately, Inaga II resisted the temptation back then. ”

"As one of the most powerful psionics of his time, it would have been easy for him to transfer his soul, right? After obtaining the technology of Echo, he was able to transform people who meet the requirements into mirrors at will. ”

"Know that the men of Inaegar II at that time were prestigious...... Even if he wants eternal life, I am afraid that there will be young people who worship him and can't wait to sacrifice their bodies to become the flesh of his new generation walking in the world. ”

"Just like when my family was in the past, when I got this secret method, the first thing I thought of was to make him immortal."

Perhaps, it was this almost divine worship that made Inaga II decide to reject this method of eternal life.

Because he understood the great temptation of eternal life, Ian was able to understand what great interests and future Inaga II rejected at that time.

After a few more moments of waiting, Ian sensed that it might take some time for Shark and Andor to wake up, so he used his foresight to observe their future.

After making sure there was nothing serious, he went around to explore.

The giant eel is gone, and Patrick hasn't caught up, presumably because the giant eel has fought with him after losing his target.

And Isengard is now with Master Gosai...... Ian didn't know if Isengard was ready to take on Patrick after hearing his hints, but with Master Gosai here, it should be fine.

Following the gently flowing underground river, Ian observes the man-made and natural tributaries that flow around him.

There is also a bit of a bad thing about the Foresight Horizon, that is, when there is no danger, even if there is a medium like the Frost Butterfly, you can't see which direction is the direction you want to go...... There is indeed a difference between danger, but danger or not does not mean that Ian needs to do it or not.

And at this time, you can only choose a random way to gamble.

Ian chose an upward river, because he heard a slight movement from the other side of the river, not the sound of water, nor the sound of a monster, quite regular, like the sound of machinery running, which made the boy a little curious.

It didn't take long for him to see the source of the sound.

That's a person.

Knock, knock, knock.

The renovated semi-natural cave is supposed to be a rest stop for maintenance personnel built here by the pre-era civilization, and the remains of a decaying riverside maintenance hut can be seen, and in front of it is a closed metal door.

The metal door was not protected by the corrosion-resistant inscriptions of the rooms around the former sacrificial site, and is now almost completely rusted, but it is still strong.

Knock, knock, knock.

And a naked humanoid figure that looked extremely similar to the previous deformed person was pounding hard on the door.

Ian clenched the sword in his hand, he thought that the next moment the aberrant would turn his head and attack him, but he didn't think that the other party didn't think he didn't exist at all, and he was still banging on the metal door that had been dented many times with a regular rhythm.

Knock, knock, knock.

He was still pounding, muttering something incoherent.

"You have to go back to the central control room, you have to go back to the central control room, you have to go back to the central control room, you have to go back to the central control room......"

There were still many bones in front of the metal door, people, beasts, and monsters, most of which were already ossified, but some were still rotting.

Pick up a long bone, which is presumably the vertebrae of some kind of beast, but completely hardened, more of a stick than a spine.

Similar aberrations have occurred everywhere, and every corpse has been parasitized.

Knock, knock, knock.

When Ian walked behind the deviant, he was still knocking on the door, the boy squinted, the silver-blue halo flickered, he seemed to have found something,

Snap, he swung his sword, and the deformed man's head was shattered, but there was nothing inside.

Only a growing pink tapeworm is wriggling.

The action still hasn't stopped, he's still knocking on the door.

"The head is empty, and you are still knocking on the door."

Saying lightly, Ian slashed the flesh of the deformed man with another sword, his belly was torn apart by his own vertebrae, and along with the internal organs, there were large and dense red and blue eggs and tadpole-shaped larvae.

These worms are eating away at flesh and blood, strengthening themselves, and merging with each other, linking the neural structures in their bodies and reshaping all the perceptual structures in the parasited.

But even so, the muscles of this humanoid figure dragged the already broken body and climbed towards the gate.

"We have to go back to the central control room...... Protecting the ...... of the First Ecological Laboratory No...... The Great Elder can't be allowed to succeed......"

The still-intact mouth and larynx were still squeezing out broken sounds that humans could no longer understand, and only a teenager with a silver chip could understand through analysis.

And these words brought him new doubts.

"Can't let the Great Elder succeed?"

He muttered to himself with some confusion, and then looked at the parasitic deformed man under his sword: "Strange thing, according to the clues, isn't it the Great Elder behind the parasite?" ”

"What's going on?"
