What Li Tai didn't expect was that Gao Ping not only pushed the abacus to the market. Various abacus were also made. There are strange shapes, small and exquisite, and there are expensive and atmospheric.

With the promotion of abacus in schools, it is slowly known to the people of Youzhou. Therefore, abacus has also become a hot commodity in Youzhou. Almost one of all the businessmen is a man.

For the sake of practicality, of course, buy that kind of ordinary abacus. For the sake of novelty, it is natural to buy those strange shapes. There are also those with extraordinary status, and those who buy are of course those who are expensive and magnificent.

Since you want to make this calculation a big hit, you can't avoid publicity and promotion. And there's no better way to advertise than to practice. Therefore, all the shops to which the Thirty-Three Heavens belonged began to use the abacus to settle accounts.

And Li Tai also paid a part of the tribute to Li Shimin, but it was not sent to Chang'an by Li Tai himself. Instead, it was sent to Mozhou City by train, and then sent to Li Shimin by Sun Chong, the chief of Mozhou Thorn History.

……

"How come you husband and wife have time to come and see your father and the palace." Eldest Sun Wujian looked at Eldest Sun Chong and Li Li and asked with a smile.

"Isn't it okay for the son to miss his mother and father? You have to have something to do to see you. Li Lizhi pouted and said coquettishly to the eldest grandson.

"What are the things that have been left behind? Show it to me. Seeing the several large boxes brought by Changsun Chong, Li Shimin asked curiously.

"Father, this is sent by the emperor's brother to his father. It is said that it can help the household to calculate better. Eldest Sun Chong handed over Li Tai's abacus to Li Shimin, and then said.

The abacus in Li Shimin's hand is not an ordinary abacus, but a piece of gold and jade abacus created by Gao Ping himself for Li Shimin.

The skeleton of the abacus is all made of gold, and the beads of the abacus are all emeralds. And each abacus bead is carved with a five-clawed golden dragon, and the abacus skeleton is also carved with a dragon and a phoenix.

It can be said that this abacus is absolutely priceless, and Li Shimin can't help but love it when he holds it in his hand. Although Li Shimin didn't know the usefulness of this abacus, it was worth liking Li Shimin from this workmanship alone.

"It's a very delicate thing, but I'm afraid it's a little too expensive. Isn't it a bit overkill to use them as an account? Li Shimin opened his mouth and asked the eldest grandson Chong.

"My father didn't know that among the abacus sent by the emperor's brother, there was only this golden abacus. It was specially prepared by the imperial brother for his father. The other abacus is made of wood, and the instruction manual for the abacus is also included. The eldest grandson Chong said to Li Shimin.

Hearing that there is a manual for this abacus, Li Shimin said to Changsun Chong: "I don't know how to use this thing, since there is a manual, let's take it for me to see." ”

The instructions explain in detail how to use the abacus. and the formulas used, which are addition and subtraction, and the nine chapters of algorithm analogy. and multiplication and division.

After Li Shimin saw it, he couldn't help but start fiddling with the abacus in his hand. With the crisp sound of the abacus beads impacting, Li Shimin was tired of fiddling.

After a long time, Li Shimin opened his mouth and said to the eldest grandson: "Your son's head, I really don't know how it grows. It was able to make such an amazing thing. With it and the Flying Bear Heavenly Calculation, I am afraid that the calculation is no longer a difficult task. ”

"Father, now this abacus is not only in the hands of my father, but also in the thirty-third heaven. And the price is only a dozen yuan. The eldest grandson Chong said to Li Shimin.

"When did your royal brother make a loss-making deal, and he gave me these abacus in order for me to advertise him. I'm afraid that the abacus in the Thirty-Three Heavens is definitely not only a dozen pennies, right? Li Shimin asked the eldest grandson Chong with a smile.

"Father, the manufacturing process of this abacus is very simple, I'm afraid it won't be long before people in the world can make it themselves. How could the royal brother make much profit on this. The eldest grandson Chong said to Li Shimin with a smile.

"Of course, ordinary abacus is easy to make, but just like this abacus in my hand, I'm afraid that in the world, except for his Momen Gao family, there are not many skilled craftsmen who can make it." Li Shimin said with a smile.

Li Shimin knew Li Tai too well, and he knew that Li Tai would definitely not just make ordinary abacus for sale. Because as Changsun Chong said, the way this abacus is made is too simple. Therefore, the monopoly effect cannot be achieved at all.

So Li Tai will definitely put the business opportunities elsewhere. That's what these luxury abacus are. The materials used to make these abacus are either gold or jade, and they are definitely not available to ordinary people.

This is also the standard that Li Tai has always been doing business, that is, to make money from rich people. Because only a rich man can make him richer.

"Father and Emperor really expected things like a god, and the imperial brother did launch a sky-high calculation in the Thirty-Three Heavens. And according to the propaganda, this abacus is unique in the world. Definitely will not produce a second one. ”

"But the price is a bit ridiculously high. The most expensive amounted to thousands of taels of silver each, and if it was to achieve a better collection value, it had to be purchased in sets. The eldest grandson Chong said to Li Shimin with a smile.

"You said to buy in sets, what is the situation?" Li Tai asked the eldest grandson Chong in confusion.

"The royal brother launched the Tiangan abacus, respectively according to A, B, C, D, and Wu has been heptoxin non dec, and these ten heavenly stems have made ten abacus. What else is the zodiac abacus, what heaven, earth and man are three abacus. ”

"What other names are Yin Yang Abacus, Five Elements Abacus, and so on. But one thing is the same, and that is that all abacus is unique. It also has a special imprint of the ink gate. The eldest grandson Chong said to Li Shimin.

"This kid is going to make a fortune with this again, I'm really worried that one day, all the money in the world will be taken by him to Yan Kingdom." Li Shimin said with a sigh.

"Father, as far as the sons know, these thirty-three heavens have thirty percent of the father's profits. So while the royal brother's income is full of trenches, the father's income will definitely not be less. At this time, Changsun Chong was beside Li Lizhi and said to Li Shimin with a smile.

"Don't go around the bend with me there, I think you're putting your mind on me. But I can tell you directly that all my money is of great use, but there is no idle one for you. Li Shimin looked at Li Lizhen and said.

"When did my father learn as stingy as my brother, you are the king of a country. You must not learn those bad habits from the imperial brother, otherwise I am afraid that you will be ridiculed by the world. Li Li said playfully to Li Shimin.

Li Lizhi's words made the eldest grandson on the side laugh more than once. So he smiled and said to Li Shimin: "This precious daughter of yours is as sharp as his imperial brother. It seems that if you take out some money, I am afraid that your ears will not be quiet. ”

"A few well-informed princesses, look at what you have been taught by Li Tai's kid. Remember, you can't let him take Xincheng with you again. Otherwise, none of my princesses of the Tang Dynasty will not be a barbaric princess. Li Shimin sighed and said to the eldest grandson.

"Father, the emperor and brother also have a letter, let the son personally hand it over to Huang." Eldest Sun Chong took out Li Tai's letter from his bosom and said after handing it to Li Shimin.
