(Weibo to see the picture, to help understand, D: green light shadow)

The so-called ghost relay, that is, choose a closed square room, by 3 people standing in a corner of the square, after turning off the lights in order, 1 person ran towards the empty corner, after being in place, the person shouted, then the person in the corner behind the person began to run, and shouted after being in place, and so on, until someone was in place, and heard two shouts at the same time, then turn on the light and find that the 4 corners of the room have all been people, and the extra person is a ghost, It will look exactly like the last person to shout.

Because the ghost will only appear after an uncertain number of running laps, and the darkness is all running against the wall, there is no sense of direction, so the average person cannot remember which of the three should be in which position, so it is impossible to distinguish which of the two people is a ghost and which is a human.

Feng Yan looked at Xiao Lu, who looked exactly the same, these 4 bear children didn't have a scared expression at all, Feng Yan secretly slandered himself, I think the 4 of you are probably not people, and said that the extra one is a ghost, so buddy, I found it, is it even if I complete the task of Xuanyuan's dream, this is not a ghost.

In fact, Feng Yan thought about it like this, he knew that the real wandering ghost was definitely not here, strictly speaking, this was not the realm of the school.

Xiao Huang took over the topic and said: "We started to play the ghost relay here around 4 o'clock in the morning today, and after a while, a fake little green appeared, and we couldn't find which one was fake after Xiao Hong turned on the light, so please big brother, you come to help find out the fake little green." ”

Feng Yan stared carefully at the two identical little greens, and the two little greens looked at Feng Yan at the same time, showing their white teeth and smiling brightly.

Feng Yan said in his heart, you two won't be ghosts, looking at the two of you, it seems that you want to collude to talk to me together.

However, he turned to look at Xiaohong and Xiaohuang, and found that these two bear children were also like this.

Feng Yan tapped his fingers on his temples, and then said, "Now, I'll ask the two of you some questions one by one, and when I ask one of them, the other can't interrupt or interject, can you do it?" ”

The two little greens nodded at the same time, and Xiaohong and Xiaohuang said on the side: "Big brother, don't worry, this requirement will definitely be met, as long as you can find out which one is false and which one is true, it's fine." ”

Judging from the appearance, it is obviously impossible, under the intervention of the system, these two bear children are definitely carved out of a mold. If you want to distinguish which one is true and which one is false, you can only find some flaws in his words by asking, so as to find the true and false Xiaolu.

Feng Yan first pointed to Xiao Lu on the left, let's call her Xiao Lu A, and asked: "You say first, you tell me, at the beginning of the game, where did you stand, and when it ended, where were you located?" If there are some clues that need to be added, or that you feel are beneficial to you, you can also say it. ”

After speaking, Feng Yan also pointed to the four corners of this room, and said to Xiao Hong and Xiao Huang: "You two also cooperate, let's stand in the position where the game started at that time." ”

Xiao Hong cooperated and walked to the southeast corner, Xiao Huang walked to the southwest corner, and Xiao Lu A, who was questioned by Feng Yan, walked to the northwest corner.

"OK, now I'll replace it with numbers, Xiaohong is the No. 1 position, Xiaohuang is the No. 2 position, Xiaolu A you are the No. 3 position, and the rest is the No. 4 position. That's how you started when the game started, right? ”

Little Green A nodded and said, "Yes, I was in the No. 3 position at the time. ”

Feng Yan nodded, signaled her not to speak yet, and turned her head to ask Xiaohong in position 1: "Did you start clockwise, or counterclockwise?" ”

Xiaohong replied: "Clockwise." ”

Feng Yan snapped his fingers and said, "Understood." Then he asked Midori A again: "When the game is over, what position are you in?" ”

Little Green A said: "I don't know how many laps I ran, when I shouted after I was in position, I heard a voice not far from me shouting, we knew that the ghost appeared, at this time I found that I was in the No. 2 position, and in my counterclockwise position, that is, the No. 1 position, there was an identical me, and in my clockwise position, that is, the No. 3 position, it was Xiaohong, and the No. 4 position was Xiaohuang." ”

Feng Yan tapped the outside of her thigh with her fingers, thought for a while, and said, "Do you have anything else to add?" ”

Little Green A said: "After Xiaohong shouted, I started to run, there was only a faint moonlight in the house, I couldn't see clearly, I was very scared, and when I shouted after I was in place, I heard her voice, and I knew that the ghost had become my appearance." ”

Little Green A grinned and pointed to Little Green B, who had not moved or spoken in the center, and there was no sense of fear at all as she said, and Little Green B also responded to her with a smile, this bear child looks like a good relationship.

I can't see where you're afraid!

Feng Yan secretly scolded himself, but he still nodded, walked to Xiao Lu B, squatted down, muttered for 1 second, and asked a very simple question: "Is Xiao Lu A's words right?" ”

Little Green B replied: "She is a lie, she is a fake, at that time I was actually in the No. 1 position, Little Green A was in the No. 4 position, and Xiaohong was in the No. 2 position, and Xiao Huang was in the No. 3 position." ”

After hearing this, Feng Yan immediately pointed at Xiao Lu B and said: "Bear child, you are a fake, don't pretend to be with me, please parents tomorrow!" ”

Little Green B said in shock: "No, don't wronged me!" ”

The other three bear children also rushed to the central position, and Xiaohong said, "Do you have any basis?" ”

Feng Yan said: "Just now when I didn't start asking, Xiao Huang said when he answered, and found that two voices, that is, after the ghost appeared, it was Xiao Hong's light, which had become an established fact before I started asking, and later in Xiao Lu A, I got a consistent answer."

And Xiao Green A's elaboration logic is very clear, there is no confusion, her words are very credible, and there is nothing wrong with it.

On the other hand, Xiao Green B denied Xiao Green A's elaboration as soon as she came up, and also moved the most undesirable direction, allowing Xiao Hong to leave the No. 3 position, which is the fixed position of the switch, so she is of course an impostor. ”

After Feng Yan finished speaking, Xiao Lub's figure gradually disappeared, and the audience in the live broadcast room booed.

"Damn, this puzzle is too easy."

"That's right, as long as you are careful, it's not hard to guess."

"Why didn't you guess it just now?"

This puzzle may seem simple, but it's actually a test of keeping every word of the NPC in mind, and then using the switch as a key hint in a seemingly unrelated topic during the inquiry.

Because whether it is a little green A or a little green B, it is possible to lie, when unsure, which one can not be trusted, you must use the way of inducement to ask, if the question is too direct, and the one asked happens to be an impostor, then it is easy for the other party to know their true intentions, so as to lose the breakthrough point.

In fact, as soon as Feng Yan entered this room, he noticed that the switch was in the No. 3 position, and he began to think after receiving the puzzle, thinking of using the switch as a breakthrough, and finally thought of using the starting position to make a fuss, induce NPCs, and successfully determined the authenticity of Xiao Lu A's words.

Originally, he thought that Xiao Green B would say that he agreed with Xiao Green A's statement, if that was the case, then he had to find some way to find a breakthrough point from Xiao Green B and distinguish which one was an impostor, but he didn't expect Xiao Green B to directly deny Xiao Green A's statement, so it can be determined that Xiao Green B must be fake.

"Oh! Big brother is so powerful! ”

Little Green A excitedly raised his hands and cheered.

Feng Yan lowered his head, showed a cold smile and said, "I haven't finished talking yet." You are also a fake. ”
