Song Che walked to the cage and slammed off the black cloth, and sure enough, there were twenty-three male and female servants and twelve Bactrian camels.

"Mr. Arhan, thank you for your kindness, but there are enough servants in Song's team, I don't need them, I can take this camel, as for the people, let them go."

These nomadic tribes, most of which were slave regimes, and these two-legged servants were not as valuable as four-legged camels.

Arhan reluctantly squeezed a smile, "These twenty-three slaves, the male slave is strong and powerful, and the female slave is delicate and moving, this is the practice gift that our Great Khan has designated to give to Mr. Song, you can't refuse a piece of kindness." ”

Even so, it was not good for Song Che to refuse, and he said, "But will this camel be a little less?" You see, there are more than 2,000 people in my team. ”

Arhan had a calm face: "These are all purebred Bactrian camels, in the Gobi Desert, one can be worth five good horses, Mr. Song should not be too greedy." ”

"Why don't you do that? I also have a question about 'the same cage', and if Mr. Arhan can answer it within a stick of incense, I don't want this camel, but if you can't answer it, how about giving me ten more camels? Song Che asked with a smile.

"This ......" Arhan looked at Song Che, looking a little hesitant.

Song Che said again: "Of course, if Mr. Arhan has no confidence, or if your country can't give you camels, forget it, I won't embarrass you." ”

With such a thrill, Arhan immediately gritted his teeth and agreed: "Okay! Ten horses is ten horses, Mr. Song, please ask! ”

"Kyoka, Kamika!"

"Okay boss!"

Lu Jingxiang lit a stick of incense in public and held it high in his hand.

"Listen up."

Song Che pointed to the cage behind him and asked: "In a cage, there are two kinds of animals, one is a chicken and the other is a donkey, they have a total of forty-four legs, if you turn a chicken into a donkey, if you turn a donkey into a chicken, there are fifty-two in total, may I ask, how many chickens and how many donkeys are there in the cage?" ”

There are many variations of the Olympiad problem of chickens and rabbits in the same cage, and the confusion caused by the replacement of chickens and rabbits is only the simplest one.

Alhan was a little confused, and hurriedly learned the fruit, picked up the branches and converted them on the ground, he used the same method of addition and subtraction, too backward, too clumsy.

"No, no......"

He smoothed the sand over and over again, wiped his sweat over and over again, and looked at the incense over and over again.

"Incense, more than half burned." Lu Jingxiang broadcast loudly, which undoubtedly increased his psychological burden.

"Mr. Arhan, if you really can't solve this problem, you can also ask your subordinates for help, otherwise you will go back and sue your Great Khan, saying that I am not understanding people and bullying you." Song Che's sarcasm is undoubtedly another pressure.

Arhan gritted his teeth.

"My lord, do you want to ...... Let's grab a few chickens and a few donkeys to demonstrate, shall we? ”

"But...... This has no head, only feet, how many are you looking for? ”

"Catch five chickens first, and then find six donkeys?"

"Fool, five chickens have ten legs, and six donkeys...... Six donkeys, how many legs do they have? ”

His subordinates, these reckless men of the Hu tribe, scratched their ears and cheeks one by one, and didn't even understand the question, what can they do to help?

"A stick of incense, it's time!" Lu Jingxiang threw away the incense stick and announced loudly.

Looking at Arhan again, he was so angry that he broke the stick into two pieces, and in front of so many people, he didn't even have the qualifications to cheat.

"Guo'er, teach Mr. Arhan another lesson." Song Che greeted with a smile.

Guo'er responded obediently, picked up the branch and wrote it again and again in front of Arhan to solve the problem:

"What was originally forty-four legs, but later became fifty-two, shows that there are more chickens than donkeys. The chicken has two legs and eight more legs, which means that the chicken has four more legs than the donkey; Then take the first forty-four feet, subtract the extra eight feet, and finally get thirty-six feet; These 36 legs are the same number of chickens and donkeys, and with the division taught by Teacher Song, we can finally get that there are six chickens and donkeys, and there are four more chickens than donkeys, so there are ten chickens. ”

She looked back at Song Che again: "Teacher Song, am I right?" ”

Song Che gave a thumbs up: "Crooked Rui, Crooked Rui Good!" ”

Guo'er said, "But the chicken is not a donkey, and the donkey is not a chicken, right?" ”

Song Che glanced at Arhan, who was beside him with a gloomy face, nodded and said, "Yes, this is the most fundamental problem of human beings, but some people don't understand it. ”

"Who are you satirizing in this little girl!" Arhan scolded angrily.

Frightened, Guo'er hurriedly hid behind Song Che, "Teacher, no one is afraid of a chicken or a donkey!" ”

"Mr. Arhan, she's just a child, so why bother with her? Don't lose the demeanor of a great country! ”

Song Che smiled: "Then, ten camels, Song will laugh." ”

Arhan gritted his teeth, trying to remain indifferent, "Aren't there just ten camels?" I have a lot of Hu country! ”

Song Che bowed and thanked: "This time it is a long way to the Western Regions, so I won't delay the time, and I also ask Mr. Arhan to let the guards open the door and let us out." ”

Arhan snorted lightly, waved his hand at the guard, and the jade gate slowly opened, but he saw that outside the wooden door, there was a large iron door.

"My lord! Oh no, we accidentally broke the chain that opened the iron door! I can't get out for the time being! "A Hu soldier came to inform.

Arhan pretended to go to the door to check it out, and first scolded bitterly: "What are you eating! Don't you know that Mr. Song is going to leave the customs today? Why can't it be overhauled in advance! ”

Subsequently, he turned back and apologized to Song Che: "I'm really sorry, Boss Song, in order to prevent someone from detaining the pass, we also added an iron gate outside the wooden gate of Yumen Pass, all blame this group of lazy soldiers for not overhauling, so that the chain of the lifting iron door is rusty, and there is no iron-making process in this vicinity, if you want to rebuild the chain, you have to go back to Dadu, I'm afraid it will delay you for ten days and half a month." ”

"You old fox, you are obviously deliberately making things difficult for us!" Nangong Yue said.

Arhan said coldly: "Mr. Song, please take care of your subordinates, she is really rude!" ”

"You-"

"Hey."

Song Che raised his hand and motioned for Nangong Yuemo to speak again, he smiled faintly and asked: "Mr. Arhan, I know that you didn't stump me when I was in Jinling in the past, and I was not convinced, so I came to the Yumen Pass to block me, since this is the case, why make up excuses, it seems to be extremely hypocritical, just ask the question." ”

"Good! It's still Boss Song's refreshment! Arhan stopped pretending, and pointed to the big iron gate and said:

"This iron gate weighs a thousand catties, if Boss Song can pull it up without chains, he will let you pass."

He asked proudly: "Boss Song used one finger to tell my country's strong men to stand up, so it must be easy to pull up this iron door, right?" ”

Laugh at...... Villain's face!
