Looking at the accounts with sweating and blurred eyes, Chen discontent and Chen Ziqu were really a bit like the name!

Chen dissatisfied with these people, and thought that these people were too slow, so they were bored and waited for a long time...

Chen Zicong looked very complacent, feeling that the two brothers had grown up now, and they were actually ten times faster than these people!

Chen Zixuan was complacent about the results he and his brother quickly calculated at one time, and the accountants of the Ministry of Revenue and the Provincial Eunuchs stared at their calculated data and compared them...

The further down, the more shocked everyone here is!

The results calculated by these two brothers in half an hour are mostly the same as those calculated by them after spending five hours. Even if there are different ones, after recalculating, it is obvious that either of them has calculated the wrong calculation!

Accurate, fast, time and effort!

The performances of these three accounts were of course live broadcast to Li Er, Tang Jian, Qin Li and others. Every detail can be seen clearly!

"God! What kind of thing is this made by a god? There is such a way?" Tang Jian held an abacus in his hand and shook it loudly!

Li Er originally thought that Yang Gangguen might have been a little exaggerated, but he didn't expect such a result now!

"Yes! Tell me quickly! It's so amazing! I also find it incredible..."

"Your Majesty, it's not a big deal!

This thing can be seen with a wooden plate and a dozen beads. The magical thing lies in the summary calculation formulas, that is, the words you recite when the accountant is planning to make a calculation!

This is not a magical art, nor is it a magical art. These are some melody. After memorizing it, as long as you understand the principle of abacus, no matter how complicated the number operation is, you can get the answer in an instant!”

When Qin Li was taking medicine in a Chinese pharmacy, he often used abacus to calculate large and small data. For this reason, he learned to plan his abacus. He accidentally learned to learn more and more thoroughly. He originally thought that he would not be too useful in his life, but he did not expect that it would come in handy here...

Qin Li played with the abacus, recited the formulas of "three, five, two, and other words", and calculated a string of numbers according to Li Er's requirements...

"It's so great! Huai Dao. Although this is your home school, you must take out such things and the Tang Dynasty needs them everywhere! Don't worry, you won't be given in vain! I will give you a reward!"

"Your Majesty! I just said before that we must strive to be a noble person, a pure person, a moral person, and a person with low interest, which will benefit the people of the Tang Dynasty.

If you have said such a big thing, how can you ask you for rewards to bring out such a little thing?

I can write the mantra and write a book "Basics of Abacus". Your Majesty, you will issue the world. I will introduce the abacus and its operating principles in detail. I believe that anyone who is a good writer can understand it. At that time, officials at all levels will recommend it and it will be popularized in all parts of the Tang Dynasty..."

There are many ways to make money. Abacus is promoted as soon as possible, which will be of great help to build a Tang Dynasty that can connect with the world and connect with the world according to the idea in the future!

When building a road, the first thing to do is to consolidate the roadbed!

Now you have to accidentally open the stall slowly. By the time everyone in the world notices it, the matter has already been done...

"Huaidao, I admire you for having such a heart at such a young age!

However, you still need to reward it!

You must not refuse. I am starting from the standpoint of the Emperor of the Tang Dynasty and rewarding you!

You are a role model and a benchmark. Only by giving you generous rewards can the thousands of people of the Tang Dynasty have the same mind as you. You no longer have your own unique skills and cherish them. You can have good things and good skills, so that the road of the Tang Dynasty can be carried out faster and more steadily!"

"Your Majesty's wise!"

"Your Majesty's wise!"

"Father, wise!"

The three present quickly praised Li Er...

Since you want to reward, I have to accept it funny. After all, if you have too much money, you won’t collapse the Qin Mansion’s treasury... Qin Li was complimenting and thinking about messy things in his mind...

It’s Lantern Festival tonight!

Chang'an opens today, on the fifteenth and sixty-seventh day of the first lunar month, if nothing big happens, there will be no curfew at night...

When Qin Li left, he had designed the Kongming lanterns and even connected dozens of Kongming lanterns, intending to build a lantern dragon. Chang'an Lantern Market wanted to build a lantern. The family not only had to go see it, but also put their own...

Therefore, as soon as the palace calculation competition ended, Li Er and Li Chengqian were busy attending the dinner. In the evening, Li Er even went to the lantern market to light the headlight tree of various lanterns presented by the people of the world, and announced the beginning of the lantern festival...

The people of Chang'an, who have been in peace for twenty years, have already recovered. Therefore, the Lantern Festival is getting more lively every year. Since we want to create a prosperous era, the atmosphere must be started first!

Everyone in the Qin Mansion is busy and not busy. The family members of the family have already paid extremely high salaries. Their aunts and aunts have mobilized and are also receiving jealous salaries!

There was still not enough manpower, and in the end, all the aunts and aunts and aunts and aunts were mobilized...

In order not to blow the entire Qin Mansion into the sky, Qin Li had to borrow a match factory that had not yet started to work for fireworks and firecrackers! In the matter of dispensing medicine, the detained death row prisoners were only allowed to dispensing medicines for matches, but now the work has started to dispensing medicines for the Qin family!

Of course, these death row prisoners were locked in the dark and sunny medicine room, only telling them that the powder they were prepared was poisonous and that they could make people survive, not die, and not have bad thoughts...

So those people can only match the powder according to the ratio... they don’t know what this thing is for!

Qin Li originally wanted to tell them that the medicine powder was highly toxic and that people would die if they were eaten. Qin Liu reminded him that some of these death row prisoners were afraid of death, while others could not die. If they told them that they were extremely toxic, those who wanted to die would eat it and want to die. If they told them that they could make people survive but not die, no one would dare to try it randomly. After all, they could not live or die. They would be afraid of suffering and torture... The result was very good!

In this way, the devilish operation, the fireworks and firecrackers with blood and sweat met the needs of Chang'an nobles as much as possible, and even expanded to the needs of the nobles...

On the Lantern Festival, the sky was just getting dark, and those slutty nobles began to set off fireworks and declare their abilities... It is indeed necessary to get a large number of fireworks and firecrackers, which requires face and ability. The Qin family provides this thing in a limited supply...

The most slutty person is Cheng Yaojing. This person is actually very wise. He looks big and thick, but in fact he is as careful as a hair. He is innocent and innocent, eating and drinking, making a big noise, bragging and fucking, and fashionable things that he wishes to wear! Just like jade, now the treasure is so precious that it is hard to find gold in Chang'an City. The old fairy has three pieces of big and small hanging on her body, and they are all top-quality...

This tells Li Er that I can be arrogant and domineering, rich and can walk sideways in Chang'an, but I am simple-minded and have no rebellious intentions...

Therefore, this old fairy was still able to make peace in the Gaozong Dynasty... Of course, this is in official history... Qin Li can't explain how the situation develops now!

It was not dark, and the first person to set off fireworks was Cheng Yaojin!
