Xianbei thought about this problem over there: the invention of the abacus should have been very early, and it was almost natural to transition from the knotted rope of the primitive society to the abacus, which was almost a natural thing.

Where did the bookkeeper know anything about the "Northern Song Dynasty" and "Eastern Han Dynasty", and looked at him stunned.

Xianbei was still unsatisfied, he said, "How do you think there is such a thing? The abacus has been there for a long time. ”

The bookkeeper got impatient and said, "Childe, what's the matter with you?" ”

Xianbei said, "I want food." ”

The bookkeeper was wary of Xianbei and said, "You, grain? Rice is fifteen dollars a liter, noodles, sixteen dollars a liter. ”

Xianbei said, "I don't have money......

The bookkeeper said, "Gold and silver are fine, and they can be converted into money." ”

The bookkeeper didn't let Xianbei finish his words, so Xianbei had to use the original sentence structure to say, "I don't have gold or silver either." ”

The bookkeeper grinned and said, "Then what about you and me?" ”

"No, boss," Xianbei said patiently, "I tried to tell the whole story several times, but you cut me off." ”

"You say," said the bookkeeper, "I won't cut it off this time, you say." But there is one thing, our store is a small business, and there is no credit. ”

Xianbei smiled and said, "Some words, some thoughts, have not changed for thousands of years. So, I want to exchange my horse for food with you, I don't know if it will work? ”

"Putting the horse on the shelf?" The boss said, leaning over to look out, but he retracted his neck and said, "What do I want a horse for?" I have a horse that I can use, what do I need a horse for? ”

Xianbei thought to himself, this is a profiteer - he clearly saw my horse salivating, but he denied it in every way. It's nothing more than trying to keep the price down. So, Xianbei said, "You can convert gold and silver into money." ”

"Well, in this case, you can consider," said the boss, "I will have to work hard at most to make my son a good job." ”

Xianbei praised him and said, "That's it." ”

The boss stepped down from the inside platform, opened the fence door on the cabinet, walked out, and said to Xianbei, "Look at your horse?" ”

Xianbei waved his hand and said, "Please." ”

The two of them walked out of the door and looked out, and saw a carriage with two horses tied to it, and the driver of the carriage was leading a horse, and the owner of the grain store said, "Three horses? ”

Xianbei said, "The two horses tied to the back of the car. However, if it is suitable, three horses is not impossible. ”

"Three?" The proprietor of the grain store weighed it and said, "A hundred liters—we weigh the liters of the dough." ”

"A horse?" Xianbei said.

"Neon!" The owner of the grain store jumped to his feet and said, "Three horses! ”

"After two thousand four hundred and forty-one years, you will definitely suffer a lawsuit if you do business like this," Xianbei's heart was on fire, and he said, "If you kill these three horses, you won't be able to hold a hundred liters of horse meat." ”

The grain store owner rolled his eyes twice, probably thinking that what Xianbei said made sense, so he said, "I bid, you can bargain." ”

Xianbei calmed down, suppressed the fire in his heart, and said, "In this way, horses and rice noodles are different, my three horses, three colors, let's talk about them one by one?" ”

"One horse at a time?" The owner of the grain store was worried about the conditions offered by Xianbei, and he said, "Okay, just one horse at a time." ”

Xianbei pointed to the black and white horse behind the car and said, "That horse is thinner and weaker, and its hair is relatively dull, which means that it has an age, I can ask for less, forty liters, it can't be too little, a living horse!" ”

The grain store owner Gaba Gabba mouthed, wanted to say something, but didn't say it.

Xianbei saw that he didn't say anything, but acquiesced, so he continued, "The jujube red horse on the left, fat and strong, with a shiny coat, shows that it is young and strong, why should it be changed to one hundred and ten liters?" ”

The owner of the grain store let out a long voice "ah" and said, "Is it worth it, a horse for a hundred and ten liters?" I haven't heard anyone change it like this. ”

Xianbei grabbed the words of the grain store owner and said, "So, there were people who exchanged horses for grain before?" ”

The grain store owner glanced at Xianbei, did not answer Xianbei's words, but pointed to the horse led by Mu Tong and said, "You rode this horse?" ”

Xianbei said, "Yes, isn't this horse better?" ”

"Count!" The owner of the grain store said, "Just change the two horses tied to the back of your car, 110 liters, and change them when you do them, and if you don't do them, you can go to another house to see." ”

Xianbei said, "I won't go to other homes, one hundred and thirty liters." ”

"One hundred and twenty liters, this is my last bid, if I am willing to change, I will change it, and if I don't want to change it!"

Xianbei thought about it, from three horses to two horses, and spared an extra twenty liters, but it was okay, so he agreed.

And so it was delivered.

Xianbei has never seen "liter", and when the boss takes it out, it is so small! Just say.

The boss said, "I told you, our liters are the liters of the face, which are different from the ordinary liters, and you heard that. ”

Xianbei thought about it, and didn't distinguish it from him, a profiteer, so he said, "Okay, okay, let's bag it." ”

Profiteers bagged. One hundred and twenty liters, only five bags were packed, and Mu Tong was carried into the car, and they left.

Back in the grove outside the city, Xianbei told the men about the change of faces, and the first thing to blow up was Gao Feng, he said, "What's the difference between this and robbing?" Two horses in exchange for five bags of noodles! It is said that Zhao Guoren is mellow, and this boss is very cunning! ”

Xianbei waved his hand and said, "There are good and bad everywhere, forget it, I don't have the same knowledge as him." Let's go, let's go. ”

On the road, Gao Feng was still babbling, he said, "Five bags of noodles, how many days can you eat?" I can't eat for ten days! The boss's heart is also dark! ”

Xianbei didn't squeak when he heard it, he thought to himself, they have resentment in their hearts, and they don't let people babble?

This time, instead of going around the city, they entered through the south gate and went out through the north gate. When I walked to the grain store, the boss came out to watch the excitement. Xianbei rode on the back of the barge, and the boss didn't recognize it.

Xianbei scolded in his heart: I am in this situation, otherwise I would not let you take such a big advantage!

The two horses that were replaced were tied to the wheels of a car under the window, and that car had a horse in the wheel.

The two horses that were exchanged out screamed when they saw Xianbei and their brigade passing, and the two of them still knew each other. Xianbei's heart turned over: People say, greedy people are ruthless, you can't say what crime you have to suffer in this family.

The city of Beili is not big, it is a small city that is a mile square, Xianbei and a group of people quickly walked out of the north gate, and walked two kilometers away, only heard the hooves of the barge and the horse, and there was no human voice at all, even the peak was silent, and did not make a sound. Xianbei is very curious, looking back at the peak, where is his shadow?

Xianbei asked, "What about the peak?" ”

No one knew where he was, they all said that they didn't pay attention, and they never saw him again when they walked out of the city gates. Xianbei thought for a while, and suddenly shouted, saying, "It's broken! ”
