"Asker." Medea ran to Asker, who was still inspecting the body, bent down and called him.

"What's wrong?" Ask asked calmly.

"That's it..." Medea briefly explained everyone's reasoning.

All in all, the girls hope to invent a way to identify their companions to prevent them from continuing to copy impostors after this mutation and try to sneak into the team like last time.

However, the embarrassing part is that any information that enters everyone's memory will be read by this mutation. When the counterfeit is copied later, it will be copied perfectly, causing the method to fail.

Asker:? ? ?

Wait, we are just a mutated copy of the next psychic type, are we actually that complicated?

After thinking about it for a long time, Asker realized that when he was not a professional player, it seemed quite complicated for a player to play this type of mutated dungeon.

As an epoch-making super-intelligent holographic game "Iron and Fire", many so-called mutation copies have created epoch-making new gameplay.

For example, psychic dungeons will use intelligent AI to disguise themselves as teammates and deceive teammates in the team.

In the early stages of the version, the method of deception was very simple and crude. It was to create a clone and suddenly sneak into the team, and then speak and move simultaneously with the copied original character throughout the whole process, so that players could not tell who was the real person and who was the AI.

Although the holographic game cabin prohibits external programs such as YY Voice, it cannot stop players from going offline. So just go offline and ask and it will become clear.

In the middle and later stages of the game version, a more insidious game design appeared: subcontracting.

Use fog, teleportation and other plot-killing methods to forcefully separate the team, and then create a team of clones to deceive the separated teammates.

Through server big data and advanced algorithm training, these clone NPCs are much more intelligent than ordinary NPCs. They can pass the Turing test and simulate no less than tens of millions of speaking personalities, regardless of whether the copied original owner's personality is cold, straightforward, Gentle or talkative, it can imitate 99% of them.

In addition, when players communicate online, no matter what method is used, the server will record it accordingly. As long as it is information that you directly see or hear, the server will determine that the clone's AI also knows it based on the corresponding algorithm, so that these clones can be disguised so seamlessly that ordinary people cannot recognize it at all.

How do players crack it? Still relying on cunning means, exchanging passwords offline, and checking passwords online, the server has nothing to do.

However, in this world, 80% of it is not feasible - at least the obstacle of "not being able to go offline" is getting closer and closer.

There is a simple solution, which is to teleport all the girls back to Hearth Island, leaving Aske alone to deal with the changes.

As long as I play alone, no matter who you become, it will be of no use to me. I will kill whoever I see, and I will pass the level by pushing all the way.

However, this opportunistic approach undoubtedly goes against Aske's original intention of training the team. If everything is unresolved on Fire Island, do you still have to think about it when you encounter problems in the future? How can we grow without thinking?

Seeing that Medea was still thinking hard, Asker smiled and reminded her:

"That's it. You ask Hidrifa to carve a seal with any pattern, as long as it's not symmetrical."

"Then, ask Nora to borrow some carbon paper."

"Carbon paper?" Medea asked curiously.

"Each piece of carbon paper should be interspersed under a page of note paper." Asker said, "Then close your eyes, randomly rotate the seal a few times and press it firmly. Then move it a certain distance to the right, rotate it again and press it .”

"Since you are rotating the seal with your eyes closed, you will not know the angle at which the two patterns on each piece of paper are placed side by side."

“Finally, with your eyes closed, tear off the note paper, crumple it into a ball, and distribute it to everyone in the team.”

"Since no one knows what's on the paper, naturally they won't know about the mutation either."

Medea suddenly realized: "Although we don't know what's on the paper! But the patterns on every piece of paper are the same!"

"So when I encounter a replica, I just have to ask it to open the paper and compare whether the pattern on it and mine are the same. Then I will know whether it is a real person or a replica!"

"As expected of the leader! It's awesome!" The more Medea thought about it, the more wonderful it became. She hugged Asik excitedly, with little stars popping out of her eyes.

Asik broke away from her embrace awkwardly, coughed, and said:

"In short, when encountering such a change, you need to use your brain more, do you understand?"

"Got it!" So Medea couldn't wait and explained this method over the psychic communication channel, which immediately made other girls marvel.

This method cleverly makes use of the mechanism of psychic mutation that "can only be copied by reading memory", which isolates the code from everyone's memory and can also be easily identified.

"If you want to optimize it further, you can stamp it with your eyes closed, then take pictures with your mobile phone and send them to everyone in groups." Sheila said, "When you meet, just open the photo album and compare the photos."

"It's just that we don't have mobile phones." Nora took out the carbon paper from her bag, "Let's use Asker's method first."

"Why do you have carbon paper?" Eleanor asked curiously.

"I will write down some important information twice," Nora replied, "and then tear off one page and keep it separately to prevent the notes from being lost."

On the other side, Hidliba took out a potato, cut it skillfully with a knife, and then carved several simple patterns on the cross section.

"Hey, wait!" Eleanor became even more curious, "Why are you carrying a potato with you again!"

"Emergency food," Hildrifa replied, "In case there is something to eat one day, it can save lives."

All the things you carry with you are so strange! Eleanor couldn't laugh or cry.

After finishing the carving quickly, Sidrifa closed her eyes and pressed twice heavily on the notebook Nora had laid out with carbon paper.

Then tear off the printed pages, crumple them into balls, and distribute them to everyone in the team.

Matthews looked on in confusion. Because Medea spoke through the psychic communication channel, he didn't hear a word.

Since he caught a glimpse of the girls from Cang Qing Sword dividing paper balls, he could only guess that the other party had come up with an effective code method for identification, and he immediately started scratching his head and head.

What exactly is the solution? What can I do!

"That..." Matthews thought about it, and finally decided to be shameless and ask their leader Aske for advice.

As soon as he opened his mouth, Medea immediately came out and sneered:

"Want to know how we identify ourselves? Let's make a price first."

Fortunately, my mother was there, otherwise the leader might have told the other party the secret directly due to his casual character, which does not regard money as money.

"Damn!" Matthews immediately lost interest. You want to charge me money for this simple and crude trick?

He returned to the team glumly, called a few of his more clever confidants, and explained the situation.

"In other words, this mutation can copy acquaintances in our memories and pretend to be them to deceive and infiltrate us." One of the confidants said, "In this case, we can agree on a secret code..."

"Once you know the secret code, Mutation will know it by reading your memory." Matthews said angrily, "Wouldn't Mutation's copy also know it?"

"But if we don't know the secret code, how can we check it?" Another confidant asked in surprise.

"This is the crux of the problem! The crux!" Matthews said impatiently, "The girls opposite can figure it out, but you can't figure it out? Use your brain!"

The confidants were speechless. Aren’t you also unable to figure it out?

But after all, Matthews is the leader and can be the boss without being unreasonable. So everyone thought hard for a long time, and suddenly a confidant had an idea and asked for confirmation:

"Captain, you said they just made notes in their notebooks, then tore them out, crumpled them into paper balls, and distributed them to everyone?"

"Yes." Matthews said, "But I didn't see clearly what they wrote. Moreover, since the code was clearly written down, the person who wrote it must have a memory, right? Wouldn't it still be possible to be affected by this incident? Do you understand the changes?"

"I understand." The confidant said confidently. "The key to this method is that the guy who wrote it is a fool."

"Fool?"

"That's right, a fool with a photographic memory."

Matthews and others suddenly felt enlightened:

"yes!"

"Find a fool to write it. Write the same code on all the papers. After he writes it, he will forget it!"

"This way the mutation won't be able to read his memory!"
