Three days later, the construction of Heti in Qinghe Town officially began.

More than 300 households in the town should have dispatched more than 300 people, but they didn't expect more than 600 people to come, almost all the young and middle-aged men were dispatched, more than 60 brand-new wheelbarrows, more than 200 rattan baskets, bamboo baskets, and more than 100 hoes and shovels, all of whom were emotionally lined up in the area that had already been painted with grass and wood ash on both sides of the Xiaoqing River.

At the same time, there are villagers who have rushed over from Shili and Eight Villages, all carrying hoes and tools, and even Xiaohe Village has more than ten under the leadership of Uncle Ma of the village.

Xiaoqing River is not wide, the widest point is only twenty zhang, now it is the time of winter and spring, the river water is shallow, so the narrowest place is only about one zhang, you can step over, but because this river is several canyon streams converge, so once it comes to the summer rainstorm, the mountain flood is coming, almost instantly the Xiaoqing River water will swell a few feet, and because there is no river embankment to block, the river water is easy to flood the farmland on both banks, the time is short, the crops will be completely finished, Especially in April and May, when all kinds of crops are flowering and bearing fruit, the river water is soaked for two or three days, and basically all the year's harvest will be lost.

Therefore, the rising water of this small Qinghe River is almost a huge hidden danger in Qinghe Town since ancient times, and it is more helpless than the wolves and tigers in the Wild Wolf Valley and the previous nest of mountain bandits.

The matter of building the river is said by knowledgeable people in Qinghe Town almost every year, but in the end it was not successful, because the previous Lidian was an old antique, and it was not repaired despite the repeated persuasion of Liu Po and others.

But today, this unprecedented huge project destined to be recorded in the history of Qinghe Town is about to begin, and all the villagers are very excited, except for the hundreds of young people who participated in the construction of the river embankment, all the men, women and children in the town are also gathered on the river beach, and more than a thousand pairs of eyes are all on the young man standing on a small dirt slope by the river.

"You're all set, aren't you?" Chen Xu turned his head and asked Liu Po.

"Lidian rest assured, all the subdivisions have been sent to each team, all the tools and carts have been distributed, the women, girls and children who boil water and deliver water have also been arranged, and the ambulance in the health center has been fully prepared!" Liu Po's face turned red with excitement and turned a little black.

"That's good!" Chen Xu reached out and took a horn made of wood from Niu Dashi's hand and raised it to his mouth.

"Ladies and gentlemen of Qinghe Town, the construction of the embankment of Xiaoqinghe begins now!"

"Oh~hooh~"

Chen Xu's voice was still chatting and echoing on the river beach, and thousands of people on both sides of the Xiaoqing River almost simultaneously issued an extremely primitive and excited cheer and shout, and the hundreds of villagers and villagers who participated in the construction of the river embankment all entered the river beach barefoot, and the hoes and shovels were raised and fell almost at the same time, and those who were not assigned tools directly used wooden sticks and hands to pry the stones, and then carried them to the wheelbarrow and pushed them to the position of the river embankment that had been planned, and handed them over to the people who had been waiting there to be responsible for building the river.

Not only the registered villagers, but also many of the old, young, women and children who had been standing on the riverside and watching the excitement rushed down to the river beach to help pick up stones and soil

Qinghe Town, which had been quiet all winter, suddenly became in full swing in an instant, with all kinds of laughter and shouts echoing on the mile-long river beach, and the scene was a fiery mess.

"Engong, Wuya has never heard of such a situation where people are so enthusiastic about servitude!" Yu Wuya stood beside Chen Xu with an iron sword, and said with emotion as he looked at the crowded situation on the mile-long river beach.

"What Brother Wuya said is that we have never seen such a scene!" Wang San, Wang Wu, and the other four guards also nodded together, with inexplicable sighs on their faces.

Chen Xu was very satisfied with everything in front of him.

The blooming flowers, the tender green wheat seedlings, the willows of Turui, and the tender yellow weeds and these poor peasants in ragged clothes who are working in full swing, although they are poor, are full of hope, and this embankment is hope, the hope that sprouts in the spring.

"Yu~~" A few horses came from the direction of Pheasant County in the east of the town, and then stopped by the river together, in addition to a few soldiers, Jiangbei Pavilion and Liu Qingshan who were riding on horses and two middle-aged people dressed as scribes looked at the villagers who were building the river on the river beach in front of them, and all of them showed surprised looks on their faces.

"Brother Jiang, why are these serving civilians so excited and enthusiastic?" A middle-aged scribe with a somewhat round face asked in surprise.

"That's true, I've seen many people who have served in the service, all of them have sad faces, but why is it so relaxed and comfortable here, it's strange!" The other scribe, who was about the same age as Jiangbei Pavilion and looked handsome and wore a jade crown, also showed surprise on his face.

Jiang Beiting knew that Chen Xu was a freak, so he didn't show too much surprise, stroked his beard and pointed at Chen Xu standing on the dirt slope and said, "Chen Lidian is there, just ask him if you have doubts in your hearts." ”

"It's okay, let's go and ask Brother Jiang what you call the prodigy Xiao Lidian!" The round-faced scribe couldn't wait to clamp the horse's belly, and several horses rushed towards Chen Xu.

"Engong, it seems that the county order is coming!" Listening to the cheers and cheers in the lively crowd, Yu Wuya looked back and said to Chen Xu.

Chen Xu hurriedly turned around, and sure enough, he saw Jiangbei Pavilion and two scribes of the same grade riding through the wheat fields on the bank of the river, so he hurriedly tidied up his clothes and took Niu Dashi and Liu Po up to greet him.

"Chen Xu has seen the county magistrate!" Chen Xu bowed.

"I've seen the prefectural commander!" Niu Dashi and Liu Po also hurriedly saluted together.

"Virtuous nephews are exempt!" Jiangbei Pavilion waved his hand and the two scribes got off the horse, and said with a smile on his face: "I accompanied two friends to go out today, just a few days ago I heard that your Qinghe Town is going to build a river embankment, so I went all the way to take a look, but I didn't expect to see this lively scene, which made me very pleased!" ”

"Your Excellency praises it! The construction of the embankment is a move to benefit the township and the people, the villagers are enthusiastic and reasonable, the small Qinghe River will flood almost every year, the two sides of the 10,000 acres of fertile land are soaked in water after the yield is reduced or even the harvest is out, resulting in the difficulty of tax and grain collection, the villagers are not hungry, now while the spring tide has not risen, I plan to repair the embankment on both sides, once completed, my Qinghe Town will no longer be safe from flooding! Therefore, the villagers are very enthusiastic to cooperate, and there is a lively scene that adults can see in front of their eyes. Chen Xu said respectfully.

"Well, the construction of the embankment is indeed a major measure for the benefit of the township and the people, if it is built well, it must be a huge merit, I will tell the merits of the virtuous nephew to the county keeper, and at the same time to commend the stone on the embankment, the name of the virtuous nephew is enough to make the descendants of Qinghe Town remember and praise it!" Jiang Beiting said with a very satisfied smile.

"Come, virtuous nephew, I'll introduce you to you, this round-faced person is Zhang Cang, who is now serving as the imperial historian in Xianyang, and this time he came to Nanyang for a routine spring inspection, which is my old friend in Xianyang!" Jiang Beiting pointed to the round-faced middle-aged scribe and said.

"Zhang Cang?" Chen Xu was slightly stunned, this name seemed to be a little familiar, but there were so many celebrities in the Qin and Han dynasties, he was stunned for a few seconds and didn't think of it, but in order not to be rude, he hurriedly bowed and said: "Chen Xu has seen Zhang Yushi in Qinghe Town!" ”

"No courtesy, no courtesy, my imperial history can't control your head!" Zhang Cang laughed and looked harmless to humans and animals, and seemed to be a very easy-going breed.

"This dashing person is Feng Zi'an, the deputy head of Nanyang Academy, and Zhang Yushi is the same brother as the disciple, and he is a disciple of the Confucian sage Xun Guo!" Jiang Beiting pointed to another handsome middle-aged guy with a dashing appearance.

The two students of Xunzi, when Chen Xu was surprised, also hurriedly saluted again: "Chen Xu has seen the master of the courtyard!" ”

"Hehe, on the way here, I heard that Jiang Xian Ling talked about many anecdotes about you, but I didn't expect that many novelties such as threshers, curved plows, horizontal rakes, cocoon cars, and warm couches were all researched and produced by you, could it be that Chen Lidian is a disciple of the Mo family?" Feng Zi'an smiled and returned the salute, but the smile seemed to be a little fake.

And Chen Xu's face was a little dark, your uncle, you are Confucian, ask me if I am from the Mo family, the two Confucianism and Mo are mortal enemies, Confucius was degraded by Mozi like a piece of shit, what do you mean when you just meet.

But Feng Zi'an is just a deputy master who opened a museum and taught apprentices, not even an official, Chen Xu naturally didn't bother to be too polite to him, so he shook his head with a smile and said: "Xu is not a Mo disciple, and not all the people in the world who are skilled in the organs are Mo disciples, just like Confucian apprentices do not believe in Confucianism!" ”

Feng Zi'an, Zhang Cang, and Jiang Beiting were all stunned at the same time.

"Lord Fengyuan, Xu is not wrong!" Chen Xu asked deliberately.

Feng Zi'an's handsome cheeks twitched slightly, and the smile on his face was very stiff, "Chen Lidian is naturally not wrong, the Confucian sage Confucius once said that there is no class, and it is not surprising that there are a few deviants among Confucian disciples!" ”

"Haha, I don't know what will happen if Lord Zuo Li Si's words are heard?" Chen Xu laughed happily.

"Hmph, what does he know, although my Feng Zi'an is the same brother as him, I don't want to be with him!" Feng Zi'an snorted coldly with an ugly face and said.

Yo, awesome!

Chen Xu could only secretly give Feng Zi'an a thumbs up, and at the same time admired Feng Zi'an a little, and dared to scold Li Si in public, this integrity is still good.

"Brother Feng, don't be annoyed, today is to come out to play, don't be in a bad mood!" Jiang Beiting hurriedly persuaded, and at the same time glared at Chen Xu helplessly.

Zhang Cang glanced at Chen Xu thoughtfully, then looked up at the busy and noisy people on the riverbank and said: "Although Chen Lidian is young, he has long wanted to come to see him, because Cang has always liked to study arithmetic, and in July last year, Jiang County Lingtuo brought me a ninety-nine multiplication table, and I was very happy to see it, so after coming to Nanyang this time, I couldn't wait to find Jiang County Ling, and asked him to take me to Qinghe Town, which is to discuss arithmetic with you!" If I can get some inspiration, I can also compile the arithmetic problems that are often used in civil affairs into an arithmetic book, so that my Great Qin craftsmen and officials can easily calculate ......"

"Nine chapters of arithmetic?" Listening to Zhang Cang's words, Chen Xu's mind was like a lightning bolt, and he suddenly remembered a person named Zhang Cang in history, who was the first person to compile the mathematics "Nine Chapters of Arithmetic".

"What is Nine Chapters of Arithmetic?" Zhang Cang asked suspiciously.

"Ah, haha, Xu just suddenly remembered something, Zhang Yushi is not going to be surprised!" Chen Xu hurriedly wanted to skip this topic.

But Zhang Cang seemed to be very interested, and nodded after thinking about it: "Nine chapters of arithmetic, this name has a great meaning, nine is the extreme of numbers, there are nine numbers in the Zhou metric system, plus there are nine multiplication tables, well, the name of my book is indeed apt, it is much better than the arithmetic book I thought before!" ”

I'll go, it's so shameless!

Chen Xu couldn t help but slander Lao Tzu just exclaimed You took it as the title of the book, but ...... Seem...... It seems that the nine chapters of arithmetic in later generations were compiled by Zhang Cang, but it was only made out in the Han Dynasty after the collapse of the Great Qin, and if the guess is right, the middle-aged man with a round face in front of him is the Zhang Cang in history.

Because it will not be so coincidental that there are two people with the same name and surname who both like mathematics in the history of the same period, and judging by time, it is also roughly in line with Zhang Cang's age, because the history records that Zhang Cang lived for more than a hundred years, from the Qin Dynasty to the period of Emperor Jing of the Han Dynasty, he lived for two dynasties, and spent years to survive six or seven emperors.

This also illustrates a big problem, people who love to use their brains live long.

Chen Xu was a little worried about himself, and then glanced at Yu Wuya, he was actually more worried about this foodie, this is a typical person who doesn't like to use his brain.

"What do you think I'm doing?" Yu Wuya looked back at Chen Xu inexplicably, with a lollipop in his mouth.

"It's okay, you keep eating sugar!" Chen Xu waved his hand weakly.
