Ivan, Karl, Alex, Ben, Eguchi Plains are back on the second floor.

Each of them had puzzled expressions written on their faces.

Ivan was the first to speak: "There is indeed a fog, and the touch is like a cold wall of ice that cannot be penetrated. ”

Karl asked, "Why is there a fog?" ”

Ben echoed and asked, "Do we really have to kill people who don't belong in this world before we can get out?" ”

Eguchi Hihara said: "If there is someone who does not belong to that world, how do we find that person, whether that person is one, two, or three, and if there are too many people who do not belong to that world, what should we do?" ”

Eguchi Plains is an excellent police officer, and he immediately thinks about many possibilities.

The rules do not say that there is only one person, if there are too many people, then the number of people who are not in this world and the number of people in this world are inconsistent, and it will become a dead end.

Looking at this scene, the audience had some curious discussions.

"yes, how do you find it?"

"This seems like a cumbersome project, right?"

"Everyone meets for the first time, and they know each other for the first time, and they don't know the roots, so it's inevitable that someone will hide something!"

“...”

The audience also discovered that when they met for the first time, it was almost impossible to tell who was from this world and who belonged to another world.

If people from other worlds speak late, they choose to deceive in order not to die.

As a result, the situation becomes a dead end.

At this moment, in the picture, Jiang Zhe looked around, and after finding that there was nothing unusual, he ordered: "Everyone is spaced apart, one person sits every 20 meters, with me as the leader, I will make a single inquiry about you, and when I find that person, I will gather you together." ”

As the words fell, he took out two black pistols from his waist, pointed them at the scene, and threatened with a smile: "I believe everyone has no opinion, right?" ”

The corners of Ivan's mouth twitched, this guy, you have a gun, what other opinions can we have?

Soon, everyone got up one after another, helplessly separated the seats, and after confirming that everyone at the scene was spaced 20 seats, Jiang Zhe ordered again: "Officer Leon, please close the exit to prevent anyone from escaping." ”

Although Leon was unhappy, in order to find out, he decided to temporarily become Jiang Zhe's subordinate.

Ignoring Kuaidou, Jiang Zhe looked at Ben in front of him, "Professor Ben, what is 911?" ”

Ben was stunned, "911 is a series of terrorist attacks that occurred on September 11, 2001 at the World Trade Center in New York. On the morning of September 11, 2001, two civil airliners hijacked by lawbreakers crashed into Building One and Building Two of the World Trade Center respectively. ”

Jiang Zhe nodded silently, "The time when the Xia Kingdom was founded." ”

Ben's expression was a little helpless, "Little friend Jiang, are you serious, ask such a basic question to a history professor, 1949.10.1!?" ”

Jiang Zhe smiled innocently, and asked again: "Are there zombies in your world?" ”

Ben was completely annoyed by Jiang Zhe's question, "No!! ”

As the words fell, the corners of Jiang Zhe's mouth were slightly outlined, "Okay, you can go aside." ”

Seeing that after asking the question, Ivan on the side came over and sat down opposite Jiang Zhe, "Come on, I'm ready, Jiang Zhe." ”

Jiang Zhe thought for a moment and asked, "'Ship of Theseus' If the wood on Theseus's ship is gradually replaced until all the wood is no longer the original wood, then is this ship still the original ship?" ”

Ivan was really shocked by this question, "What kind of problem is this, can you tell if I am not from this world?" ”

Jiang Zhe shook his head, "Can you answer?" ”

Ivan didn't think about it, "It sounds like a philosophical question, I don't know anything about philosophy, I'm a science student." ”

Jiang Zhe nodded slightly, "Okay, are there zombies in your world?" ”

Ivan immediately gave the answer: "No! ”

"Got it, next!"

Then Alex walked over, a little flustered, and after taking a deep breath, after making enough preparations, "Come on! ”

Jiang Zhe looked at the person in front of him, "Pinocchio paradox, if Pinocchio says, 'My nose will be longer immediately.'" What will be the result? ”

Alex's eyes were a little subtle, and he thought about it and said, "What are the preconditions for this question?" ”

Jiang Zhe said: "If it lies, its nose will become longer." ”

Alex was a little interested in the question, "I see, once Pinocchio lies, the nose grows longer, and then he says this, does its nose get longer, if it gets longer, it's a lie, if it doesn't grow, but it does lie... First of all, it tells the truth, then the nose does not get longer. Since his nose won't get longer, it proves that it's a lie. So how long should it be? Or is it not going to grow...."

Seeing that Alex was extremely interested in the paradox, Jiang Zhe looked helpless, "Okay, you can leave, Alex." ”

"I haven't answered yet, you don't ask?"

"Well, there's no answer to that question, I already know the answer."

"But you were a little loud just now, didn't you ask, 'Are there zombies in your world?' didn't you ask me this?"

Jiang Zhe asked curiously, "Is there one?" ”

Curious, Alex asked, "What if I say yes?" ”

Jiang Zhe's eyes narrowed, and he took out his pistol, "Will you die, now?" ”

Alex hurriedly shook his head, "There are no zombies. ”

Jiang Zhe nodded with satisfaction, "You can leave, next!" ”

Then Karl walked over and sat down in front of Jiang Zhe.

Jiang Zhe asked: "Do you know the tram problem?" ”

Karl frowned and thought for a moment, "Is there such a problem?" ”

A subtle smile appeared on Jiang Zhe's face, "Well, I see." Are there zombies in your world? ”

Carl shook his head, "No! ”

Hearing this, Jiang Zhe nodded, "Next!" ”

At this time, Eguchi Plain came over and sat down in front of him.

Jiang Zhe asked: "Achilles, or 'Zeno's paradox' - this paradox makes the turtle start 1,000 meters ahead of Achilles and race against Achilles, and assumes that Achilles is 10 times faster than the tortoise. When the race starts, Achilles runs 1,000 meters, and the time is t, at which point the turtle is 100 meters ahead of him; When Achilles finished the next 100 meters, he took time t/10 and the turtle was still 10 meters ahead of him. When Achilles finished the next 10 meters, he took time t/100 and the turtle was still 1 meter ahead of him... In the end, Zeno thinks that Achilles can continue to approach the tortoise, but he will never be able to catch up with it, don't you think? ”

Eguchi Plains' expression was a little strange, "What kind of question is this, strange, can I answer it to prove that I am a person from this world?" ”

Regarding this reaction, Jiang Zhe nodded silently, "Okay, I know, are there zombies in your world?" ”

Jiangkou Plain's expression became more and more strange: "Are you kidding, how can the zombies in film and television works appear in the real world?" ”

Jiang Zhe had a satisfied smile on his face, "Okay, you can leave, the next one, Leon." ”

At this time, the entrance has been pulled down by Leon with a steel gate half a meter thick, there are only two entrances here, one entrance needs to climb the window to come up, the only entrance has an iron door, even if someone underneath it is impossible to break through the door to reach the second floor.

Leon sat across from Jiang Zhe, "Didn't I come with you, even I need to ask?" ”

The smile on Jiang Zhe's face was a little subtle, "Leon, what is the answer to the ship of Theseus?" ”

Leon shook his head in denial: "Philosophical paradox, there is no answer." ”

Jiang Zhe nodded with satisfaction, "What about the tram problem?" ”

Leon frowned and thought for a moment, "It doesn't seem to have an answer." ”

Jiang Zhe asked again: "What about Zeno turtle?" ”

Leon didn't think about it, and immediately gave the answer, "The Zeno turtle paradox has been ended in Planck time, and people will definitely surpass that turtle in the most extreme Planck time!" ”

'Planck time' refers to the minimum interval between time quanta, about 5.39×10-44 seconds, there is no shorter time than this, Planck time = Planck length / speed of light.

So Zeno turtle paradox, people are always one step faster than the turtle!

"Alright, Leon, I got it."

At this time, Jiang Zhe's expression was a little solemn, he looked at the five Ivan people on the right with a solemn face, and Ivan and the others also looked at Jiang Zhe inexplicably.

Leon's expression was a little serious, and he asked softly, "What did you ask them just now?" ”

Jiang Zhe stepped forward and asked softly, "Do you think there are zombies in our world?" ”

As the words fell, Leon's expression was a little evasive, he didn't answer, just stared at Jiang Zhe's gaze.

The corners of Jiang Zhe's mouth were slightly outlined, and his voice was extremely weak, "Leon, what do you think?" ”

Seeing Jiang Zhe's expression, he knew everything, and his eyes kept resting on Ivan and the others on the left, "Jiang Zhe, do you really want to ask this question?" ”

Jiang Zhe nodded solemnly: "Yes!" ”

Then Leon's eyes closed, as if accepting something, the two of them made eye contact, and finally nodded slightly, as if to make a decision.

Almost in the next second, Jiang Zhe and Leon turned around instantly, took out their pistols, and before Ivan and the others could react, they continuously pulled the trigger, "Bang bang bang!" A barrage of gunfire fell.

Ivan and the others collapsed in shock.

Seeing this scene, the entire audience was dumbfounded.
