Juancheng, the government of the government.

"Gong Xun, these money and grain accounts have been counted, you can look at them."

Lu Ren handed over several rolls of bamboo slips to Xun Yu, Xun Yu unfolded them and looked at them a few times before nodding and said, "You Yihao, you help me, I will save a lot of trouble." It's just that...... Yihao, you have to practice your words. ”

"......" Lu Ren was embarrassed but helpless about this. For a modern silk otaku, calligraphy is not generally difficult to write, let alone writing traditional characters on bamboo slips?

Xun Yu finished reading the two rolls of bamboo slips, and as soon as he looked up and saw that Lu Ren was still standing in front of him, he beckoned to Lu Ren and said, "Yihao doesn't have to be so formal, sit down." I've worked hard for you in the past two days, and I've ordered someone to clean up a living house next to the mansion, and you can go and stay there after you have eaten here, and it's more convenient for me to ask you for help if I have something. ”

At the end, Xun Yu quipped: "Yiying's food, clothing and miscellaneous items will be prepared for you, and you can rest assured, so that you will not have to live in Fengxiao temporarily, and he said that you are wasting the grain and rice in his house in vain." ”

At this time, Lu Ren already knew that Xun Yu was not the kind of person who did not smile, on the contrary, the person who could become good friends with Guo Jia would usually be the kind of person who could joke more, as long as it was not a formal occasion, he didn't have to be so serious, and he smiled at Xun Yu at the moment. It's just that Lu Ren has something in his heart at this moment, and this smile is a little reluctant.

Xun Yu is also a person who can understand people, and at a glance he can see that Lu Ren's smiling face is hiding something on his mind, and after a little hesitation, he put the bamboo slip in his hand aside, and turned to Lu Ren and asked, "Yihao has something in his heart?" Is it convenient for me to hear? ”

Lu Ren hesitated for a moment, then nodded to Xun Yu and said, "I really have something I want to ask Xun Gong." In the past two days, I helped Xun Gong calculate some money and grain accounts, and I found that one acre of land only had less than three stone of income, which ...... Isn't it too little? ”

Xun Yu looked at Lu Ren in surprise: "A hundred steps of small acres, three stones of Su per year, it's normal!" Yihao, when you help me count the money and grain accounts, don't confuse the big mu with the small mu. ”

Lu Renxin said I'm not that stupid! It happened that after meeting Xun Yu that day, Shirley sent a communication, it was nothing to do, just report each other's safety. But Lu Ren took into account his "work needs...... In fact, out of curiosity, she asked Shirley to send over the weights and measures of various eras. Then in the past two days, helping Xun Yu settle accounts, Lu Ren inevitably came into contact with the grain production of the Eastern Han Dynasty, and after a little careful calculation, Lu Ren exclaimed in his heart, "Why is the grain output of the Eastern Han Dynasty so low."

The modern acre is sixty square abbots, and the large mu of the Eastern Han Dynasty is 240 steps, and the small mu is 100 steps, which is roughly a modern mu = 1.4 large mu of the Eastern Han Dynasty = 3.38 small mu of the Eastern Han Dynasty, and a stone of the Eastern Han Dynasty is actually only 26.4 kilograms, so the harvest of one small mu and three stones, converted to the modern yield per mu, is only less than 268 kilograms of 26.4x3x3.38!

Of course, Lu Ren also knew that the land of Gunzhou was not Xuzhou. Xuzhou has a wide area of stem rice, and the traditional millet here in Gunzhou is mainly based on the corn at that time, and after the millet is hulled, it is commonly called millet, which is much worse than rice in terms of yield. But coincidentally, Lu Ren was bored watching TV before the crossing when he encountered advertising bombardment, and there happened to be an advertisement for millet seeds that was written down by Lu Ren because it was done well, and the advertisement said that the average millet variety yield per mu is only 300-400 kg, and their hybrid varieties are generally 800, and they can be nearly 1,000 if planted well.

Putting aside those high-yield figures that may be a bit false, and only taking the minimum value of 300, then the yield per mu of modern millet is more than 30 kilograms more than that of the Eastern Han Dynasty, which is more than one stone when converted into the Eastern Han Dynasty system. Even if it is distributed to a small mu, the yield is nearly ten kilograms, and it is dozens of catties when it is replaced by the Eastern Han Dynasty. Seeing such a gap, how could Lu Ren not be surprised? And this is still not compared with Uncle Yuan's hybrid rice, not to be mistaken, Uncle Yuan's hybrid rice is a modern mu with a yield of thousands of kilograms, I really don't know how many streets can be thrown out of this "three stones of Su Sui".

At this moment, Lu Ren saw that Xun Yu was not at ease, and he picked up the bamboo slip and had the intention of recalculating, so Lu Ren hurriedly said to Xun Yu: "Don't worry, Xun Gong, I didn't confuse big mu and small mu, but I was very surprised that a small mu can only earn three stones a year." ”

Xun Yu finally relieved when he saw Lu Ren say this, put the bamboo slips aside and said to Lu Ren: "It seems that Yihao, you have been to a lot of rich places!" It is true that in some places, if the fertile land is cultivated properly, it can earn as much as four or five or even ten stone per year, but one is that such fertile land is extremely scarce, and the other is that in the early years, in order to show their merits, the officials wrote books with excessive pompous style, so many of the things recorded in the books are actually unreliable. (Note 1)

Lu Ren shrugged his shoulders and said completely casually: "The yield of millet is not high, why don't you change to rice?" ”

"Rice?" Xun Yu was slightly stunned, then shook his head and smiled: "I forgot, Yihao, you are originally from Wu, and you lived in Xuzhou before, and these two fields are mainly rice. It's just that Yihao, you don't know, the income of rice is actually slightly lower than that of millet, and the seedlings of rice are much more delicate than millet seedlings, and they are not easy to plant. ”

When Lu Ren heard this, his eyebrows almost didn't screw together, and he said in his heart that it was impossible, right? Even if I have never studied agriculture, I know that the yield of rice is much higher than that of millet, and it is basically two crops a year, and in some places even three crops a year. However, Lu Ren didn't say this, because Lu Ren knew that he must have made something wrong or didn't understand, and planned to ask Shirley to get some information about this next time he contacted Shirley. And to be honest, "he" has studied the plants on the earth when he studied the earth's ecosystem, and the relevant information should be readily available.

In fact, Lu Ren, a traverser, does not know much about these things, mainly because the cultivation methods of the Han Dynasty and the Han Dynasty were far less refined than in modern times, and the degree of civilization in the south with rice as the main plant at that time was not enough, and the farming methods were even more extensive.

Shaking his head, he threw aside these things that he didn't understand at the moment, Lu Ren took a thing and put it in front of Xun Yu and said, "Xun Gong see if this thing is good or not." ”

Xun Yu took it and looked at it, and said strangely: "What is this?" It looks a bit like the beads we use for counting. ”

Lu Ren said: "I call this thing 'abacus', and the purpose is actually the same as the bead chip, but I dare to say that it is definitely much more convenient than the bead chip, and it is also easy to carry." You see, one, two, three, four, five, one more upward, and so ......on."

To tell the truth, when Lu Ren came here the first day, he saw several officials there using beads to calculate things, and one bead after another was swinging around, which made Lu Ren dizzy. Anyway, I had two spare money in my hand, so I asked the craftsman to make such an abacus roughly. As for the abacus itself, it is said that Guan Yu invented it, but Lu Ren has never seen it until now, maybe Guan Yu hasn't had a flash of inspiration to get this thing out at this time, right? Anyway, the current Lu Ren didn't want to see those beads that gave him a headache.

Xun Yu often has to deal with numbers, even if he is not a master of abacus, he has to hone into a master of abacus, and the use of the abacus itself is in the same vein as the abacus, so just after a while, Xun Yu can use the abacus to calculate, of course, if you want to do a crackling fast calculation, it is still a lot worse.

After a few more strokes, Xun Yu picked up the abacus and shook it according to Lu Ren's technique just now, and smiled at Lu Ren after the commotion sounded: "This thing is very convenient, and as Yihao said, it is also very convenient to carry it around." When I went back, I ordered the craftsmen to follow this example and make more copies and send them to the relevant officials, believing that they would also find it very convenient after they were cooked. Since this thing was created by Yihao, it is better to call it 'Yihao'. ”

"......" Lu Ren was dumbfounded, and said in his heart, "Yi Haochou"? Why does it sound like "righteousness and sorrow"? What am I worried about? So he hurriedly waved his hand to Xun Yu and said, "Don't don't, it's okay to call it an abacus." ”

Xun Yu smiled again: "Whatever you want, the abacus is the plate." ”

Lu Ren secretly wiped his sweat, and said in his heart that this kind of thing belongs to the wisdom of the vast number of working people, it is better for me not to steal his version. smiled awkwardly, took out a piece of linen from his sleeve pocket and handed it to Xun Yu: "Xun Gong, take a look at this again." ”

Xun Yu looked at it and said curiously again: "These symbols ......"

Lu Rendao: "These symbols are called Arabic numerals, but as far as I know, they are symbols created by Tianzhu people and specially used for counting them. The biggest feature is that these symbols can be written with one stroke, not as cumbersome as we have to write a word to keep track of numbers. But this thing...... I'm afraid that Xun Gong and the officials will not be able to adapt to it, so please ask Xun Gong to watch it himself if they use it or not. ”

Xun Yu was taken aback: "Tianzhu!?" When you were wandering, you went to the far west, thousands of miles away in Tianzhu!? ”

"No!!" Lu Ren hurriedly shook his head: "I'm not so good at running!" I actually learned this from a monk from Tianzhu who came to my Han mission. ”

Xun Yu also breathed a sigh of relief: "Scare me!" As far as I know, it takes more than ten years to go from the Central Plains to Tianzhu, but how old are you this year? ”

Lu Ren smiled dryly, and said in his heart Fortunately, I was prepared, and I knew that Buddhism had been introduced to China in the Eastern Han Dynasty, otherwise I really don't know what kind of trouble it would cause if I got involved with Tianzhu. I just don't know if Xun Yu, who is used to "one two and three wantons", can accept "1234".

But seeing that Xun Yu tried to write a few times according to the numbers marked by Lu Ren, he nodded: "Although it is a rune of the foreign gang, I have to admit that it is indeed much more convenient to write." Well...... It can be used by the shilling clerk and can be used after a little refinement. And Yoshihiro, the method of comparison you marked is also very detailed. ”

Lu Ren came out with this thing, to put it bluntly, he didn't want to write about those complicated and tiring "one two three wantons". But since it's to get this thing out, the corresponding logo comparison can't be sloppy. Therefore, in addition to the common "one = 1, two = 2", Lu Ren also deliberately dotted the corresponding number of dots under the ten numbers. What? Don't understand? Take a look at the cylinder tiles in the mahjong tiles and you'll understand.

In fact, Lu Ren was most worried about whether Xun Yu could accept these figures. However, Lu Ren's worries were somewhat unnecessary, because the Han and Tang dynasties could be said to be the era with the highest openness and compatibility among the many dynasties in ancient China. Perhaps it is precisely because of this that the Han and Tang dynasties will become the most glorious era of the ancient Chinese dynasties......

((Note 1: When the bottle was checking the information, I saw the iron in the Seven Sages of the Bamboo Forest, that Ji Kang said in his "Health Theory" that the good land can be ten acres and ten hundreds, which is enough to have 937 catties in the modern metric system, with an output of nearly 500 kilograms, if it is millet, it is comparable to or even more than the millet of modern general output, it is really hard to say whether it is true or false.) Here the bottle is putting this statement in the pompous statement. Anyway, I personally believe that in order to achieve this kind of yield at that time, unless it is to grow rice with two crops a year, the productivity of millet at that time is really unlikely to be achieved. ）
