"Look for me?" Robb deliberately lowered his voice and said with an old-fashioned manner: "The old man is not familiar with you, do we have a good chat?"

Listening to him claiming to be an old man, Marianne did not complain, but showed an admiring face: "You are the greatest businessman I have ever seen. You can turn everything into magic. My father often tells me that you cut cakes. The story of selling at eight and sixteen yuan, telling me the story of the one-year advance fee and zero initial installation fee for tap water, and the advertising game you taught my father, all benefited our Cotton family... "

Robb: "..."

Marianne's face blushed: "I admire you so much. I want to worship you as a teacher like Robert. He studies the style of magic, so I will learn business skills, okay?"

Robb: "..."

This is very embarrassing. It is not that Robb refuses to teach people. When he is interested, he will teach people around him all kinds of knowledge. However, if he is asked to be a teacher and systematically teach people how to do business, that will not be the case. . One is that he doesn't have this mood, and the other is that he doesn't have this ability.

To be a teacher for people is a university. In this world, there are many talented people who can't teach others. Besides, Robb doesn't think he is very talented. What he knows is all kinds of mess that he borrowed from later generations. Business common sense.

Robb shook his head: "Don't teach or teach! I'm not familiar with you. You come to visit the teacher inexplicably, my teeth haven't been brushed yet."

Marianne said: "I will pay a very generous tuition fee."

Robb continued to shake his head: "I am not short of money."

Marian felt very uncomfortable now, and her little mouth murmured pitifully, and she turned around to leave after aggrieved.

Robb felt a little sympathetic when he saw her pitiful appearance. After thinking about it, when I first went to the Magic Academy, this girl took good care of herself, asking for money and materials, she also helped a lot, so she still had to take care of her.

Is there anything that can teach her without any effort? At the same time, this thing can improve the world after it spreads!

"Ah! Yes!" Robb suddenly said: "Marian, I don't have much time to teach you business slowly, but it is still possible to lay a foundation for you. I would like to ask, your family often needs Do large numbers of customers, right?"

Hearing Robb’s greeting, Marianne turned around with joy: "Yes, we often have to settle accounts."

"So, what method do you use to calculate the math?"

Marian lifted up and beckoned to the servant who followed, who unexpectedly took a set of weird tools and placed them on the table in front of Robb.

Robb took a closer look. This thing is a large wooden board with several parallel lines drawn on it. There are also many operators like "chess pieces" on it. Each operator is made of copper, about two or three centimeters. The radius is marked with Arabic numerals from 0 to 9.

Marianne placed these counters on the board and smiled: "This is a threading abacus. Our Cotton family will use it to settle accounts. The speed is very fast."

"Oh?" Robb was very interested, and casually posed a simple math problem. Seeing Marianne quickly put the counter on the wooden board, after a while, he worked out all the problems he asked.

She was a little proud: "Godfather, I'm pretty fast, right? My father trained me to use the threading abacus since I was a child. My calculation speed is faster than my father! I am the best in the Cotton family."

Robb smiled and said: "Yes, you are really fast, but still not as fast as me, you are optimistic."

Robb stretched out his hand, fetched something in the air, and a piece of wood flew over.

He rubbed it casually, and he rubbed the wood into a large Chinese abacus. It turns out that this is an "decoration" produced by the carpenter in the game "Black Blade". This abacus is used for pure decoration on the back.

When Robb was in college, he took a few classes on abacus. Although it was not a very good abacus, he would still be able to use it.

He set his abacus and said with a smile: "You said you are the best in the Cotton family, so how can you do it? I will turn you into the best in the entire Kingdom of Gran."

Marianne looked at the abacus with a dazed expression: "This is?"

"This is also an abacus." Robb smiled and said, "Come on, you can report the bill, and I will calculate it for you."

Marianne looked confused, looked at a string of beads and didn't know what it meant, but of course it was okay to report the bill. She casually went in and out of the account. She spent X gold coins on the purchase, and earned X gold coins on the shipment... , A long bill.

Robb listened to her to report the number, and quickly fiddled with the abacus beads in his hand. Those few abacus classes in college were not forgotten, but he barely kept up. It was so embarrassing that he almost couldn't keep up and pretended to fail. . Fortunately, the Emperor of the Liver is the Emperor of the Liver. Those abacus lessons were also given by the liver at the beginning. It is not very skilled, but it is enough to abuse the "threading abacus" in the West.

Marianne finished reporting the bill, and Robb just finished typing. He closed his hand, pretending to be calm and clear, and said, "The answer is a final balance of 1032 gold coins, right?"

"So fast?" Marianne was taken aback: "I just finished the question, so you are finished?"

Robb smiled and shook the abacus in his hand, and the abacus beads made a clattering sound: "This is the power of my abacus. I am too lazy to teach other things, but I will teach you the technique of using this abacus. , Can also be regarded as a link in doing business."

Marianne looked at the abacus in Robb's hand, and then at his threading abacus, did she hesitate? He quickly threw his threading abacus to the distance, and then gave a salute: "Thank you Godfather."

"Come, come, sit down." Robb asked her to sit on the opposite side of his stone table, set the abacus, and explained with a smile: "The lower bead means 1, the upper one means 5, one on one, two on two. , Three on three, five on one go to four..."

The abacus is very easy to understand, and it will be taught as soon as you teach it, and then there will be questions about recitation and practice.

Marianne had a certain talent for mathematics, and she worked with numbers for years and months. Such a person could learn abacus very fast. It only took a short while, and she was even faster with basic addition.

I saw that she pulled the abacus beads to rattle, and said with joy: "This abacus is amazing! It's so convenient, it's really amazing. With this thing, I really have the confidence to become Gran The fastest man in the kingdom to settle accounts."

"Well! As long as you like it."

As soon as Robb finished speaking, the crystal ball on the table lit up, and it was time for Her Majesty the Queen to talk to him on the phone.

Robb didn't ask Marianne to evade, so he asked her to dial and pull the abacus beads to answer the phone.
