The child drew one of the sixteen cards at random and looked at it.

Then he told the old man the value of the card, and the woman the suit of the card.

The child asked the old man and the woman, "Do you know this card from the number of points and the cards you know?" ”

The old man said, "I don't know this card." ”

The woman said, "I know you don't know this card." ”

The old man said, "I know this card now." ”

The woman said, "I know this card too." ”

Then the child looked at the crowd: "Do you know which card it is?" ”

Ge Yun listened with a confused face: "What is this, do you speak Chinese, I know every word, but you guys say together why I can't understand it, how do you know which card it is?" ”

Qi Qian: "...... I think this show is testing our intelligence, is this another intellectual topic? ”

Yu Luo began to analyze: "The old man said that he didn't know this card, and I used my mobile phone to remember the cards that the child said just now." There are only four cards of two or more suits, namely Ace, Queen, 4, 5.

"There is only one kind of flower card for the other points, and if the child draws another card, then it can be determined by the number of points and a flower card. The old man said that he couldn't be sure that only I said A, Q, 4, 5. ”

Qi Qian followed Yu Luo's train of thought and analyzed: "Yes, the old man knows the points, and the woman knows the flower cards. Just now the woman said she knew that the old man did not know the card.

Therefore, the value of this face card can only include A, Queen, 4, and 5. Only these four can be included, there are and only these four, and only hearts and diamonds are eligible. ”

Yu Luo then analyzed: "That's right. The old man knows what the card is when he knows the points, so he can exclude the A, because if it is an A, the old man still can't tell, because there are two A's in the middle of the heart and the diamond. Now all that's left is Q, 4 and 5.

In the end, the woman said that I also knew, so the answer was locked in the block. After all, after excluding A, the old man still can't tell whether it's Q or 4. ”

Qi Qian and Yu Luo looked at each other, and both of them guessed what the final answer was.

Qi Qi looked at the child and said, "This card you drew is a 5 of diamonds."

Ge Yun was in a fog, although he couldn't understand it, but he still applauded the analysis of the two and said, "The kid turned over the cards you drawn." ”

The kid flipped out the cards he had been pressing under his hand in front of everyone.

[5 of a block]

The audience applauded in amazement, and Ge Yun instantly applauded louder.

"So powerful? You guys are so smart, what kind of major are you studying, it's amazing, what should I do if I feel like a fool when I'm with you. ”

Child: "If you guess the answer correctly, I'll give you something." ”

Then the child took an egg out of his pocket, and it was another egg......

The child said, "Remember, the egg must not be broken, otherwise something bad will happen." ”

They left the bridge, and Yu Luo took the egg and fell on the ground and experimented again, "It's a raw egg." ”

Let's get raw eggs.

Qi Qian picked up the egg and threw it on the ground again, directly simple and rude, regardless of what bad things would happen to him.

The soldiers will block the water and cover the earth.

There is still a small note inside the egg mixture, which reads "The treasure is not under the redwood tree in the back mountain"
