"Big rock!" Chen Xu put down the cup and shouted outside, Niu Dashi immediately ran in, changed into a new burlap shirt, wore brand-new pigskin sandals, and his hair was neatly combed, which was completely inconsistent with the sloppy and tattered image of the past.

"Brother Xu...... No, Lord Riden, what do you command? Niu Dashi's face flushed with excitement, and he also learned to speak in a crepe.

Chen Xu's face darkened: "Uncle Dian, go and invite Chen Lao to help me!" ”

"Good!" Niu Dashi hurriedly ran out.

Chen Xu looked at the back of this product with a smile, rubbed his teeth and twitched a few times.

Since he officially became the Lidian of Qinghe Town, the first day he returned to the village, the whole village had to kowtow to him, even Niu Dashi changed his words, called Lord Lidian, he became a fart official, and the people who got along day and night were divided, and even Chen Jiang's was careful when he talked to him, which made Chen Xu very depressed, and he didn't dare to go back to the village, and he had been living with Niu Dashi in this wooden house in the town for the past two days.

After a while, Niu Dashi came over with a white-bearded old man.

"Lidian, what's the point of calling the old decay?" The old man had gray hair, but he seemed to be in good spirits, and he asked directly without bowing his hand when he entered the door.

"Old Chen is here just in time, please take a seat!" Chen Xu hurriedly stood up and poured the old man a cup of herbal tea, and handed it over with both hands.

The old man was also very useful for Chen Xu's politeness, and after sitting down and drinking a few sips of sweet and cool herbal tea, Chen Xu said his request again.

The old man was not too surprised, because they had all heard that the newly appointed Ridian was still underage, and ...... was illiterate, so the old man began to explain some laws and decrees to Chen Xu very seriously.

And Chen Xu is also very depressed, it's not that he can't read, but he doesn't know the words of this era very well, now Lishu is not particularly popular, and Qin Li and Han Li are very different, at this time Lishu and small seal many font glyphs are still very similar, the strokes are more complex, far less simple and clear than the later Lishu, he has also looked through some of the bamboo slips left by the predecessor in the past two days, all of them are small seals, seven or eight of the ten words do not know, even Meng with guess can probably know half, as for the expression of consciousness is a confused, I basically don't understand it, and it's much more obscure than the so-called ancient texts that I learned in later generations, and I'm completely blind.

After listening to the class for half an hour, he felt that the old man was already a little tired, so Chen Xu asked the old man to go back, and then prepared to lie down and take a nap to rest.

"Your Excellency, Your Excellency!" There was a rush of footsteps from outside, and soon a middle-aged man with a hat and a burlap jacket ran in.

"What's the matter?" Chen Xu asked a little nervously.

Because this middle-aged man is a tax collector responsible for the registration of grain tax, his name is Niu Quan, he has read some books, knows how to read, and knows how to calculate, he is a senior intellectual in Qinghe Town, and he has been managing the warehouse during this time and is responsible for collecting summer grain tax.

"My lord, the rope chips used for registration have run out, I turned out the spare rope chips, and found that they were all bitten by mice, and I am in a hurry to use them now, what should I do?" The weather was already hot, and the cow was in a hurry, sweat beads were rolling down his forehead, and the dust on his face washed down several mud ditches.

Chen Xu breathed a sigh of relief when he heard this.

Nima Hei Laozi jumped, thinking that the grain in the granary was gone.

"Let's go, I'll take a look!" Chen Xu couldn't sleep, so he had to bring a hat and follow him to the granary where the tax grain was stored, and Niu Dashi quickly followed.

It is said to be a granary, but it is a wooden and stone house closed on all sides, the roof has just been repaired, covered with brand new thatch, in order to prevent the grain from being stolen, and two large dogs are also raised to take care of it, and there are no windows, only a small door.

"Look, my lord, these rope chips are all rotten, and they all fall apart at the slightest mention!" Niu Quan grabbed the rope on a wooden frame, and the small wooden sign he wore on it fell down a lot of it.

The so-called rope chip, is a simple calculation and registration tool, a hemp rope wearing a lot of small wooden cards, against the recovered grain and the bamboo slips of the countryside to collect grain records and the bamboo slips stored in the warehouse, each village will be carefully inspected by a household, after the grain and the quantity are matched, the grain will be put into storage, and at the same time the rope chip on a small wooden card turned up, and so on a village registration, and then add up the number of these small wooden cards, and then summarize and collect the record of the grain to see if there is a difference, if not, Even if the grain tax in this village is fully completed, if there is an error, then it will be necessary to find trouble with the person in charge of the grain collection team.

Rope chips, such a brainless thing!

Looking at a large pile of messy hemp rope and wooden cards that fell to the ground, Chen Xu's cheeks were swollen with emotion.

He had been inspecting the village for the past few days, and had only been to the warehouse once, and he had no idea that such primitive things were used for counting and settling accounts.

And because the predecessor Lidian was mediocre and old, he refused to replace the rope chips, which had been used for more than ten years, and they were so rotten that they were about to fail, and finally, this year, the town leaders were changed, and they were also very angry.

"My lord, there will be new tax grain delivered back in the afternoon, and we must hurry up and prepare the rope chips!" Niu Quan looked at Chen Xu squatting on the ground and touching his chin to look at the rotten rope chip, with a constipated expression on his face, and couldn't help urging.

"Well, don't worry, this matter is easy to solve!" Chen Xu stood up and said to Niu Dashi, "Dashi, you go and call the carpenter in the town." ”

Niu Dashi agreed, pouted his ass, turned around and ran.

Since Chen Xu became Lidian, as his future brother-in-law, Niu Dashi felt that he was the most trusted person of his uncle, and he also became Chen Xu's deputy.

"My lord, what matters now is to change the rope and wooden chips!" Niu Quan didn't know what Chen Xu wanted the carpenter to do, so he reminded.

"It's okay, I have my own plans!" Chen Xu looked at a flat stone slab next to him, and there were a few pieces of charcoal on it, which should be used for calculation, so he walked over and picked up the charcoal and wrote and drew on it, and quickly drew a figure of an abacus.

The abacus, as the greatest calculation tool in ancient times, is known as China's fifth greatest invention, which has begun to be popularized and applied on a large scale in the Han Dynasty, and then improved and inductive calculation methods and formulas by mathematicians throughout the ages, and has been used until the 21st century.

Chen Xu clearly remembers that when he was a child, two abacus of different sizes were always placed on the counter of the second grandfather's pharmacy, which were used to check the number of medicines caught with each other, to see each flavor of the medicine, first dial an abacus and then weigh it, and after weighing, dial out the number again on another abacus, and the weighing medicine would be poured on the wrapping paper when the two sides were exactly the same, and after grabbing a pair of medicines, check the prescription again, then bandage, and then tie it with a rope.

And the biggest role of the abacus is not to check against each other, but to calculate, and some powerful abacus masters are even faster than humans can calculate with an electronic calculator.

But the so-called generation of new people for the old,I used to like it and call it Britney,Don't like it, it's called Mrs. Niu,Abacus, an ancient thing, is destined to be swept into the garbage heap of history,Because it can't keep pace with the times,Just like the once brilliant five-stroke input method,In the face of a more convenient and easy-to-use input method,A big mess of defeat。

After the rise of electronic calculators, in the sound of zero to zero and zero to zero, the abacus quickly became an intangible cultural heritage, and it completely withdrew from the public's eyes in just over a decade.

But in fact, just a little more than a month before Chen Xu crossed over, he also saw an abacus in a county pharmacy called Hongshan in Suizhou, Hubei, where the salesman was still using the abacus to settle accounts.

At that time, he was still amazed and despised for a long time, what age was it, and there were still people using such ancient things!

But he didn't expect that in a few days, he would make the abacus through time and space in the Qin Dynasty hundreds of years in advance.
