After listening to the question, even Sun Qirui on the side frowned slightly.

If you can use your hands to perceive the front and back of a copper coin, then this is not difficult.

The key is to wear gloves.

Even if he cultivated to a high level, he couldn't use his strength to perceive the surface of the copper coin through his gloves.

Besides, if the 10 pieces are face up and the 10 pieces face down, they should be exactly the same after being divided into two groups, so only if each group has five heads up and five tails up.

This is what everyone thinks in the main hall.

Seeing that Li Feibai was pondering, Nangong Ding was proud again, and opened his mouth to order: "Let's order incense." ”

The guard picked up a stick of incense, inserted it on the incense burner, and as soon as he blew the fire, he heard Li Feibai shouting:

"Wait! This time, you don't need to order it either! ”

Turning back suddenly, Nangong Ding stared at him incredulously.

"You've solved it again?" Sun Qirui on the side was a little speechless.

"Hmm." Li Feibai nodded lightly.

"Come on." He held out his hands.

The guard took a pair of gloves and helped him put them on, blindfolding him by the way.

Nangong must have been a little unconvinced, these questions that stumped everyone in Jinglin, a country boy actually solved them in a few breaths.

This made him a little embarrassed.

Could it be that I am the dignified King of Zhao, and my wisdom is lost to a villager?

It took him more than half a day to solve these two questions.

Now Li Feibai has the answer in a blink of an eye.

Nangong will not accept it!

He walked over to the table and shuffled the twenty copper coins in order, but still ten face up and ten face up.

"Let's do it." Nangong Ding spoke.

Walking to the table, Li Feibai casually took the ten coins aside and divided them into groups.

When everyone looked at the ten coins he had taken, three were face up and seven were face up.

And the other set naturally has seven heads up and three tails up.

"Mr. Bai, are you sure you want to group it like this?" Sun Qirui saw the coins on the desk and couldn't help but blurt out.

In the eyes of the public, such an answer is clearly wrong.

There are no five on the front and back, and no matter what, the two sets will not be exactly the same.

Only Nangong Ding, who was expressionless, looked at Li Feibai's hands.

Holding the corners of his mouth and smiling, Li Feibai did not answer Sun Qirui's words.

Then, he flipped the set of coins he had taken!

It turned out to be seven heads up and three tails up, exactly like the other set.

When everyone saw this, they were dumbfounded!

And Nangong Ding, from the previous doubt, to the present gradually revealed the color of appreciation in his eyes.

This kind of misconception is a breeze for Li Feibai.

In the eyes of ordinary people, for the two groups to be exactly the same, there must be five pieces of each face up.

But they forgot that no matter how you shuffle the order and take ten coins, just flip them all over and the two sets of coins will have exactly the same number of heads and tails.

It doesn't have to be five-five.

Taking off the blindfold and gloves, Li Feibai said lightly: "Next question!" ”

"What a vain gift, I finally know, why does King Qi value you so much?" Nangong Ding couldn't help but praise.

"Lord Wang, there is not much time, please come up with the last question." Li Feibai was anxious.

Now that the Beishan army is outside the city, Nangong Mountain enters the palace to face the saint, and when he leaves the palace and wants to rescue the two, it will be even more tricky.

"This last question is the problem they gave me when the king sent an envoy to wish the country, and I thought about it for two days and two nights before solving it."

With that, he clapped his hands twice.

Two Tsing Yi guards entered the main hall, each holding a brocade box in their hands.

"The brocade box in the hands of these two people, one contains a dagger, the other contains a pastry, and the two of them, one can only tell the truth, the other can only tell lies, you can only ask one of them one question, if you succeed in finding the dagger, then I will agree to your conditions, to save the two of them."

"This ...... How to find it? ”

After listening to Nangong Ding's question, Sun Qirui froze.

The rest of the temple, some (this chapter is not finished!) )

Chapter 219: Problem Solving (II)

Didn't even hear the question clearly.

"You don't know who is telling the truth and who is lying, and you can only ask one person one question, how can you find this?" Someone opened up to discuss.

"Even the prince has been thinking about it for two days and two nights, and this kid wants to solve this problem within a stick of incense, which is simply a fantasy."

"You look at his expression, he is definitely stumped."

"Looking at his arrogant appearance just now, I can't wait to see his embarrassment.".

The people in the temple whispered.

"Brother Bai, do you want incense?" Nangong Ding asked with a smile.

There was something provocative in the words.

Without answering, Li Feibai thought quickly.

The difficulty with this question is that you can only ask one of them, and you can only ask one question.

Then, there must be a question, no matter who you ask, the answer is the same, so that you can find the dagger 100%.

What kind of questions can make a truth-teller and a liar-teller answer the same thing at the same time?

"I'll count to three, and if you don't reply, I'll order someone to light incense." Nangong Ding smiled and spoke.

"One ......"

He began to count.

What exactly is to ask? Li Feibai gently tapped his head.

"Second ......" Nangong Ding smiled at the corner of his mouth.

Li Feibai still closed his eyes and thought, his brows furrowed, and his head flew quickly.

"Three!" Counting here, Nangong Ding immediately ordered: "Come on, light incense and time!" ”

"Wow"

With a snap of his fingers, Li Feibai's eyes suddenly opened, and his whole body exuded an unparalleled momentum.

Seeing this, Nangong Ding couldn't help but be stunned, and in a trance, he saw someone's figure.

"No, I know the answer." Li Feibai said confidently.

"What did you say?" Nangong Ding didn't say anything, but Sun Qirui's jaw dropped in shock.

"Our prince has been thinking about the problem for two days and two nights, and you solved it before the tea time?"

Hearing his words, Nangong Ding's face had a complicated expression, and he didn't know whether to be happy or worried?

Ignoring everyone's reactions, Li Feibai walked over to the two guards, found one of them at random, and asked:

"If I were to ask the man next to you whether his brocade box contained a dagger or a pastry, what would he answer?"

"Dagger!" The guard replied directly.

"Okay, then I'll choose your brocade box."

After speaking, Li Feibai directly opened the brocade box held by the guard in front of him, and it really contained a dagger.

"No way, you must be guessing." Sun Qirui couldn't believe the facts in front of him.

In his heart, no one can surpass his master.

Even if Li Feibai won Nangong Ding in the game before, in Sun Qirui's opinion, it was all a fluke.

"Yes, I don't believe that there is anyone in the world who is smarter than our prince, he must be blind." The rest of the people agreed.

Only Nangong Ding, he knew that Li Feibai had this ability.

With a wave of his hand, he stopped everyone's discussion, faced Li Feibai, and asked:

"How?"
