"Three questions?" Wu Dan squinted at Li Chengxiu, and said with distrust of Li Chengxiu: "It's that simple?"

"That's right, it's three questions, and there are only three questions. Li Chengxiu, www.biquge.info the pen "Fun", said: "However, they are not simple, but three difficult questions, at least, it is difficult for you." If you do it all, then I lose, and I will obey you in the future, and I can do whatever bad things I want to do for you!"

"What bad things do I need you to do?" Wu Dan had a feeling of being insulted, and said angrily: "I want to see what kind of questions you can come up with!"

Looking at Wu Dan's contemptuous appearance, Li Chengxiu laughed in his heart: There is a time when you kid knows how powerful.

I really want to laugh three times and celebrate in advance!

That's the cool point of standing on the shoulders of giants!

Holding back the urge to celebrate in advance, Li Chengxiu began to ask the first question: "The first question, someone put chickens and rabbits in a cage, they have a total of eighty-eight heads and a total of two hundred and forty-four feet, may I ask His Royal Highness the Prince, how many chickens and rabbits are there?"

"Chickens, rabbits, what's the mess?" After hearing the question, Wu Dan's eyes straightened, and he was speechless: "Who is so boring, what do you do with chickens and rabbits in one cage? Can these two things be kept in one cage?"

Wu Dan will be this reaction Li Chengxiu was not surprised at all, but she still felt so funny that she couldn't do it, and said with a sullen smile: "You don't care about this, chickens and rabbits belong to other people, and people can raise them as they like." Still, I can tell you who is doing such a boring thing!"

"Who is it?" asked Wu Dan.

Li Chengxiu replied with a smile: "It is a rich man surnamed Wang, and a rich man surnamed Yu." "These two rich men were made up by Li Chengxiu, which can be regarded as throwing bricks and bringing out the next two questions. Looking at Wudan's strange face, Li Chengxiu smiled and said: "These two rich men are a pair of good friends, they just like to keep chickens and rabbits in the same cage and play with the hobby of guessing how many of them there are!"

"Is there anyone like that?" Wu Dan didn't believe it at all.

"Yes. Li Chengxiu nodded matter-of-fact and said seriously: "And their common hobby is not only this, they also like to drive the carriage from their respective homes at the same time, and drive to each other's homes at the same time, or at a specific regular speed of change, to see when and where they can meet each other!"

Ya, good!

What the fuck is this!

It's a nervous disorder!

Wu Dan looked at Li Chengxiu with a dark face: "So what?"

"So, the second question comes out. Li Chengxiu began to ask the second question: "Listen, the rich man's house and the rich man's house are forty-eight miles apart, and the rich man and the rich man Yu set off from their respective homes at the same time and went to each other's houses. The two people are moving forward at the same speed, the constant speed of the rich man is seven miles and two per hour, and the car stopped for half an hour because the car broke down in the middle, and after two and a half hours, the rich man Wang and the rich man met again, how many miles is the car driven by the rich man per hour?"

"It takes an hour to travel seven miles and two, is it a snail pulling his cart?" Wu Dan pointed out the mistake in the question.

"If you want to take care of it, people will do it at this speed!" Li Chengxiu said angrily: "Don't look for something to say, can you give an answer?"

Of course, Wu Dan can't give an answer right away.

Unable to answer two questions in a row, Wu Dan was deeply shocked, very frustrated, and said angrily: "Say, say, tell the third quirk of these two rich men!"

As he wished!

Li Chengxiu smiled sullenly and then asked the third question: "The third common hobby of the two rich people...... I like to build a big pool at home, make two openings for the pool, one outlet, one inlet, the two outlets are not the same size, and open at the same time to see when the pool is filled with water and when it is drained...... Isn't this hobby very fresh and elegant?"

Wu Dan glanced at Li Chengxiu angrily and did not say anything.

Although he didn't say anything, his depression was revealed at a glance, which made Li Chengxiu laugh.

Li Chengxiu continued: "Today, the two rich men got together again, because of the rich man's house, and the two of them replaced the pool of the rich man's house with two new water outlets, and they stood on the edge of the pool and watched the upper and lower water holes keep filling the pool with water, and the other keeps leaking water into the pool. It is said that the pool of the rich man's house is really beautiful, and the white stone chips of the clear water are paved, and the two pools they replaced the pool today are also beautiful, which are carved from two pieces of obsidian as a whole, and are also carved with floral patterns, which are both beautiful and exquisite......"

"Hugh doesn't care if it's beautiful or not, let's talk about it quickly!" Wu Dan only felt tortured and shouted impatiently.

"Okay, let's not talk about the beauty of the pool. Li Chengxiu muttered "I don't know how to appreciate", and continued: "If in normal times, only fill the water without opening the water outlet, it will take a whole hour to fill the pool, and if the full pool is only drained, it will take an hour and a half to drain the pool, may I ask, how long do the rich man Wang and the rich man Yu have to wait by the pool today to see the pool full of water?"

Wu Dan looked at Li Chengxiu faintly: "Where did you find these problem-solvings?

"Yes!" Li Chengxiu generously admitted: "I said it all, I want to get back some self-esteem!"

"Do you really have answers to these questions?" Wu Dan skeptical.

Li Chengxiu didn't answer, just rubbed his fingers and glanced coldly at Wu Dan's head.

Wu Dan immediately said with interest: "Okay, I know, you won't do such a tasteless thing." ”

"That's nature!" Li Chengxiu said: "I will tell you again, master, I am a noble person, a pure person, a person who is free from low-level interests!

Wu Dan turned his face away and said in a low voice: "You are still a super thick-skinned person!"

"What?" Li Chengxiu heard it, and immediately opened his eyes angrily!

"It's nothing!" Wu Dan vigorously denied it, and hurriedly said: "Sure enough, as you said, these three questions are really difficult, I really can't give the answer for a while, and allow me some time." ”

"Yes. Li Chengxiu readily responded to Wu Dan's request, and generously gave a long time limit and said: "As long as you give an answer within five days, it will count, but in this case, then I will also ask for interest." ”

"What do you want?" Wu Dan's heart pulled up the alarm bell again.

"Don't be nervous!" Li Chengxiu said: "I will neither ask you for Jinshan nor Yinhai, but only ask you for a promise." ”
