"Brother Xuancheng, we are really destined. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info: "Wang Mai didn't expect to go by himself and be in the same office as Wei Zheng.

Wei Zheng was writing with a pen, Wang Mai's voice went down, and he was suddenly startled, his hand shook, and an article by the pen immediately added an ink spot. This article was about to be finished, but unexpectedly it was destroyed in the hands of Wang Mai, Wei Zheng was so angry that he couldn't speak: "You ......"

"Brother Xuancheng, I know you are very excited to see me, put down the pen first, and shake the ink dots all over."

Hearing this, Wei Zheng hurriedly put down his pen, hurriedly grabbed a piece of paper and wiped his clothes.

Wang Mai sat down in front of the bookcase opposite Wei Zheng, holding his chin with one hand and admiring this famous minister up close. "With copper as a mirror, you can be dressed; With history as a mirror, we can know the rise and fall; With people as a mirror, you can see the gains and losses. This is probably the highest praise that the ancient monarch gave to his courtiers, and he is now in front of this ancient man in front of the mirror of the ages, watching his panicked side.

"By the way, Brother Xuancheng, I still have a lot of questions just now."

"Humph!" Wei Zheng snorted coldly, but he didn't look up at him, took a piece of paper again, and continued to write the unfinished article just now.

"Brother Xuancheng, have you been a Taoist priest before? ……”

"Humph!"

"Brother Xuancheng, what do you think of Li Shimin, the king of Qin in the Tang Kingdom? ……”

"Humph!"

"Brother Xuancheng, who else is there in your family besides the lady? ……”

"Humph!"

When Wei Zheng was annoyed by Wang Mai's harassment, Zheng Changshi, who pushed the door in, rescued him.

"Lord Changshi, what happened in Luoyang last night, Duke Wei and the generals have set a countermeasure?" The two got up together to salute Zheng Changshi, and Wei Zheng couldn't wait to ask.

Zheng Changshi nodded: "It has been decided, our army will begin to besiege Luoyang on the same day, forcing Wang Shichong to surrender, if Wang Shichong does not surrender, he will lack food in the city, and he will seek a quick battle with our army. ”

"No, although our army has won many victories, there are many casualties among the brave soldiers, and the Wagang army has no treasury, and the soldiers have won the battle, and they will not be rewarded, they are all disheartened. In both respects, it is not appropriate for us to engage the enemy. Now that we are sitting on a favorable position, why does the Duke of Wei not listen to my strategy and rush to a decisive battle with the enemy? ”

"You're just a cliché." Zheng Changshi said expressionlessly, "Duke Wei has already made up his mind, so there is no need to say more. ”

"This is a clever strategy, how can it be a cliché?" Wei Zheng was a little anxious, "If Duke Wei doesn't listen to my plan today, he will regret it one day in the future." ”

"Wei joins the army, please pay attention to your words!" Changshi shouted.

"Lord Changshi, don't be angry," Seeing that the two of them became more and more stiff as they talked, Wang Mai stepped forward to change the topic, "I don't know what Lord Changshi came to tell me to wait?" ”

"The army is about to start, within two days, you two need to calculate the required grain and grass baggage clearly, there can be no mistakes, this is a military aircraft, and it must not be leaked." The attendant behind Zheng Changshi put a booklet on Wei Zheng's table, and walked away after speaking.

"No matter what, you have already done your duty, why should Brother Xuan Cheng be angry?" Wang Mai persuaded Wei Zheng to say.

"Don't conspire." Wei Zheng said angrily. I don't know if he is scolding Li Mi or himself? is really kind to be a donkey's liver and lungs, Wang Mai saw that Wei Zheng didn't care much about himself, picked up the booklet on his desk and went back to his seat to work.

The accounts of this era are still relatively easy to understand, and they are basically running accounts. However, Wang Mai's hyphenation skills are relatively poor, and it took him more than half a day to figure out the content of a page, and he wrote it down on the paper next to him.

"Huh?" Wang Mai flipped through the booklet, and suddenly had a burst of doubt, "Brother Xuancheng, come and take a look, I don't understand this point." ”

Wei Zheng had been sitting for most of the day, and his anger had almost disappeared, so he reluctantly moved his steps to Wang Mai's side and looked at the place where Wang Mai was pointing.

"Brother Xuancheng, please see, why does our army still have food to send to Wang Shichong's army? Isn't this a capital enemy? Wang Mai asked suspiciously.

Wei Zheng was also puzzled after reading it: "It can't be that the record is wrong, right?" However, although Zheng Changshi is a little pedantic, he will not make such a big mistake, so I will ask him in person. ”

"Brother Xuancheng, your temper is too big, let's go with you."

The two asked Zheng Changshi, and Zheng Changshi replied that it was true that there was indeed a batch of military rations to be sent to Wang Shichong, which was agreed by Duke Wei. Wei Zheng's face changed greatly when he heard this, and Wang Mai hurriedly pulled him out.

"How can Duke Wei be so stupid?" Wei Zheng scolded.

"Brother Xuancheng, be cautious ......" Wang Mai looked around and found that there was no one, so he breathed a sigh of relief and hurriedly pulled Wei Zheng back to the room of the two.

"Didn't Zheng Changshi say just now, Wang Shichong intended to surrender, is this batch of grain to stabilize the heart of the Luoyang army?" Wang Mai said with relief. However, he knew that Wang Shichong did not surrender in the end, and he also won the Wagang army.

"Surrender and surrender, open the gates? Why make such a request, this must be Wang Shichong's delaying tactic. Wei Zheng said angrily.

Amazing, it seems that Wei Zheng is not only a good thorn in the coffin for his boss, but also extremely accurate in judging things, it is not unreasonable for this person to become a generation of famous ministers in the future. Based on the strategy he gave Li Mi alone, no matter what, the Wagang army was in an invincible position. If Li Mi can listen to his strategy, it is difficult to say which surname Li is in the end in this world. But it's a pity that Li Mi finally ended up on a battlefield of death.

"Wang joins the army, what do you mean by this square?" Complaining is complaining, and the work has to be done. As soon as Wei Zheng lowered his head, he found that Wang Mai had drawn many grids with horizontal and vertical lines on a piece of paper, which were filled with Arabic numerals that he did not recognize.

Wang Mai introduced him again with Arabic numerals.

"I can't imagine that Hu people have such a smart person, these ten numbers can be written in one stroke, such as this zero, directly replaced by a circle, more than a dozen strokes less than my Han family font, it is indeed time-saving and labor-saving." Wei Zheng exclaimed.

"As for the cells, I call them tables, and these two rows are called table headers, which represent two different measures. For example, this sentence," Wang Mai pointed to the booklet, "a person bears six buckets of rice, and the pawn brings five days of dry food, and the person is paid one pawn, and one can go for eighteen days: six buckets of rice, and two liters of food a day." The two of them ate it, and it was all over in 18 days. If you plan to return, you can only go for nine days. The two of them are paid a pawn...... "Wang Mai read the above words in one breath, "Although these words can clearly explain the military rations and grains consumed by each soldier and each soldier, but every time we have to calculate, we have to turn the page again and recalculate the grain and grass required by individual soldiers, which is very troublesome and makes people look dizzy." ”

Wei Zheng nodded: "Not bad." ”

"So I got this table by correlating the amount of grain and grass consumed by each fixed unit in a fixed period of time. This fixed unit can be a soldier or a servant, or some other combination, which is the vertical header of the table, and the time spent by the army is the horizontal header of the table. In this way, no matter how many soldiers and servants there are, and how many days they have to march, we can immediately find the corresponding data in the table and calculate it, which can greatly speed up the calculation. And such a table looks clear at a glance and is not prone to errors. ”

Then Wang Mai calculated an example in front of Wei Zheng, and Wei Zheng also used the original algorithm as a comparison. As a result, before Wei Zheng could figure out the numbers on the paper, Wang Mai had already calculated the results. After a long time, when Wei Zheng filled the fifth sheet of paper, he finally calculated the result. When the two numbers were compared, the score was exactly the same, and Wei Zheng hurriedly bowed down and said that he was taught. Wang Mai said that he didn't dare, but he was secretly proud in his heart, and a little carving insect skill frightened a generation of famous ministers.

"Actually, when I made this table, it took me a lot of time, but as long as I did it once, I only needed to use it directly to calculate it again. At the end of the day, what is expressed on the form is actually the same as the line of text, except that it is more intuitive and recognizable to our senses. Wang Mai finally concluded.

"Otherwise, although Wang joins the army's initiative seems to be commonplace, its significance is by no means more than numerical calculation, Wei can foresee that in the future, all walks of life will benefit from this initiative." Wei Zheng is worthy of a generation of famous ministers, and in a short period of time, he thought of the wide application of this kind of form that can give people a very intuitive feeling, which can be described as drawing inferences from one another.

Wang Mai thought to himself what this is, give labor and management a computer, and labor and management can immediately calculate all kinds of logistics data of the whole army for you. What line charts, bar charts, pie charts, say it and scare you to death.

"By the way, Brother Xuancheng, I saw that you used mental arithmetic just now, what about the calculation tools used in complex calculations?" Wang Mai actually wanted to ask if there was an abacus in this era, but he thought that the name of the abacus might be different in ancient and modern times, so he used the four words "calculation tool" instead.

Wei Zheng took out a cloth bag from under his table and handed it to Wang Mai, who opened it and saw that there was a bunch of wooden sticks of different lengths inside, I am afraid that there were hundreds. Counting chips? Two relatively unfamiliar words flashed in Wang Mai's mind.

"Don't you have an abacus?"

"Abacus?" Wei Zheng looked dazed.

"It's the kind of stick that wears several beads, and you just have to pluck those beads when you calculate...... Wang Mai said.

"You're talking about abacus, right?" Wei Zheng thought for a while and said, "I have seen records in some ancient books, but I have not seen the real thing. ”

In this era, there is no universal abacus? Wang Mai was a little surprised. He has always believed that the abacus is one of the most practical tools handed down from ancient times to later generations, even in the 21st century, when electronic calculators have become popular, many old accountants will play a good abacus. When Wang Mai was in elementary school, the school also taught the use of abacus, and he also won the prize of the school's abacus competition.

Getting rich, this is Wang Mai's first thought.
