The days when I pretended to be a cat in the Forbidden City[Comprehensive]

The streets of Xianyang City soon became lively as water workers from all over the country were recruited to Beijing.

Since it was an official convening, the round-trip expenses of the water workers were naturally borne by the Xianyang government office. Therefore, the review conditions were slightly harsher, and a local official had to be recommended.

However, there are still loopholes in this recommendation method, because not all local officials can be meritorious, and not all talented people can be recommended, so in order to avoid slipping through the net, this There is also a supplementary clause added to the call-up order-if it is not on the recommendation list, but if it passes the examination in Xianyang presided over by the master craftsman, it can also be compensated for the travel expenses to Qin.

That's right, come to Qin.

This call-up order did not limit that only people from the state of Qin could participate, but recruited water workers from all countries.

This is already unprecedented preferential treatment.From the time when the news left Qinchuan on the melting ice and snow until the scorching heat came, in just half a year, nearly a thousand water workers gathered in Xianyang City.

Nearly [-]% of the hydraulic workers are from foreign countries.

And just after the rainstorm season arrived, these water workers were divided into several groups and went to several areas with serious flood problems.During the rainy season, the local flood situation will be more obvious.

The so-called hydraulic engineering, if there is too much water, it can be managed, and if there is little water, it can naturally contribute.Experienced hydraulic engineers can quickly understand the situation when they go to arid and water-scarce areas by observing the local terrain. This is a hidden additional question.

Qin Wang Yingji's move is undoubtedly to put Qin's development direction in the next few years on flood control.

Not all praises were received for his move.

According to the current national strength of the Qin State, small-scale projects are fine. If it is a medium-to-large-scale project that spans more than two counties, it may cost the whole country.

This is not only the reason for the backwardness of production tools, but also the restriction of the number of young and middle-aged people in Qin State.If large-scale water conservancy projects are to be built, there is no doubt that no one can use the army.

The system of the Great Qin State is that all the people are soldiers. Basically, there are no professional soldiers. Whether it is guarding the frontier or guarding the royal city, those are all people who serve in the military. If civilian service is issued, there will naturally be fewer people serving in the military.

For this reason, there have been no less than ten heated debates in Xianyang Palace.

Fan Ju, the prime minister of Qin, the clan and generals of Qin are trying to persuade each other.

From the perspective of Prime Minister Fan Ju, Qin must now slow down to recuperate, and Qin's own economy will collapse if it continues to fight.

And judging from the attitude of the military, they certainly don't want to waste precious time on the fields. A soldier's physical strength peak period is only four or five years. If he misses this round, it means that all the soldiers now White training.Naturally, this was not what they wanted to see as Shangfeng.

Moreover, they believe that the six eastern countries have been beaten and crippled. Wouldn't it be more difficult not to take advantage of the situation to occupy more places at this time, and wait until the six countries regain their vitality?

At this time, the clan of the Qin State is completely playing the role of eating melons.But generally speaking, they are still inclined to the defensive side. This is not because they, as clans, value the people who are overwhelmed by the country, but because there is a class hatred between them and the generals that has lasted for nearly a hundred years.

But no matter how they quarreled, the king of Qin could really make the decision after all.

After Qin Wang Yingji made the final order, even if these people didn't want to, they could only obey obediently.

They didn't know that Ying Ji had no less struggle than them.As a king of Qin, he wanted from the bottom of his heart to ride horses into the Central Plains like his fathers and grandparents, behead those nobles who looked down on them, and insert the flag of Qin into their capital.

Among them, of course, was the Zhou royal family.

But he is also very clear in his heart that Qin State seems to be in a good situation now, but in fact it is on the edge of a cliff.

Qin State had followed the Lianheng route before, but it did not expect that the five eastern countries and Chu State had quietly united without knowing it, and wanted to curb the development of Qin State together.Although this matter did not succeed in the end, it also sounded the alarm for him.This kind of thing happens for the first time, and there will be the second and third time. This time, he was lucky and happened to have a son and a different person in the country of Zhao. He divides and strikes, so what about next time?

Just accept it when you see it, it's time for Qin to get up and digest it.

He sees the military's reluctance, but is there anyone in this world who is more unwilling than him?Ying Ji held the bamboo scroll in a daze.He is already 65 years old, and he has already reached the age that can be called a long life. Yingji is not sure that he has a few more years to live.

By stopping now, he left the possibility of glory to future generations.The king in this world doesn't want to be the most brilliant person in the history books?He is no less obsessed with the words "expanding the frontier and expanding the land" than anyone else, but... the word "opportunity" stands in front of him like a mountain.

But fortunately, God favored the old Qin people after all.

His eyes lightly fell on Zhao Zheng, who was sitting upright on the couch, studying with chubby Braille, and the corners of his lips curled up unconsciously.

Qin obviously has no time to look east now, but in order to prevent the five eastern countries from joining forces to attack Qin, he intends to find something for these five countries to do.

For example... I heard that Mr. Xinling, the prince of Wei State, stole Wei King's seal in order to send troops to support Zhao State, and then he dared not return to the country because he was afraid of being punished.That's a good thing to write about.

We are all relatives, how bad it would be to lose harmony for one party!No, no, Qin must serve as an envoy of peace to make peace.

You said that a dignified son of Wei Guo is staying in Zhao Guo now?People who didn't know thought it was the hostage of Zhao State who had taken Wei State.

Also, the relationship between Yan Guo and Zhao Guo is too harmonious, right?Not long ago, Zhao Guotian Dan just captured the three capitals of your Yan Kingdom, how can you help them?How dissonant it is.Compared with the relationship between Yan Zhao and Yan Qin, the relationship between Yan and Qin is obviously closer.

After all, the current king of Qin had been "studying" in the country of Yan for a long time.

As for the state of Chu... I heard that the current king of Chu has not yet given birth to a son.Oh, this is not acceptable, a king without a son is too easy to be taken advantage of by outsiders.Although female Chu is good, she is too weak. Giving birth to a child is like breaking through the gates of hell. A woman is too weak. As an old in-law and a senior, the King of Chu has the kindness he "learned" in Qin State back then. The kind and friendly old king of Qin decided to send him a few women from the state of Qin.

As for the remaining Han and Qi countries, he didn't pay much attention to them.

After Prime Minister Xuan Lai arranged these things, Ying Ji met his little great-grandson's big black eyes as soon as he turned his eyes. He stretched out his hand to signal his little grandson to come over, "What's the matter, looking at your great-grandfather like this?"

"Great-grandfather, is Mr. Xinling the son with a good reputation in the Wei Kingdom?"

"Oh, you've heard of this?" Ying Ji asked without answering, he was no longer surprised by the wide range of news about his little grandson.During this period of time, he has discovered that his great-grandson has a wide range of knowledge, not like a child over three years old. Although he is not proficient in most things, considering his age, it is rare to even have a superficial knowledge. .

"Brother told Zheng'er." Zhao Zheng pursed his lips, "Brother said he is one of the few talented young masters nowadays, but once he makes a mistake, it's hard to turn back."

"Oh?" Yingji recalled the appearance of the elder brother in his great-grandson's mouth, and then looked at the little boy in front of him. Suddenly, he became very interested in the topic of the two little children's chatting. He rolled up his sleeves, He leaned into his grandson's ear, "What did your elder brother say? You talk to your great-grandfather."

Unexpectedly, Zhao Zheng's mouth was tightly shut at this time, "Don't say it!"

He snorted, "I just finished talking to my great-grandfather last time, and my great-grandfather turned around and went to talk to my brother. After that, my brother was so busy every day that I didn't have time to talk to Zheng'er."

Yingji raised two fingers and said to his little grandson, "You told your great-grandfather quietly this time, and your great-grandfather promised not to tell your brother An. Great-grandfather has never heard of this, so he is curious."

That's it!As soon as Zhao Zheng heard this statement, even his great-grandfather who was the king of Qin had never heard of it, and he couldn't hold back his desire to show off.He leaned over and whispered, "Great-grandfather, you must not tell others that Zheng'er told you!"

"Okay, keep it alone." Ying Ji was very thorough in his work. He not only promised, but also waved all the people around him to leave.When only the grandfather and grandson were left in the arena, he heard Zhao Zheng whispering in his ear: "Brother said, the last thing he should do is to recruit customers."

"Oh?" Ying Ji raised his eyebrows high, which was beyond his expectation, "But this Mr. Wei is most well-known for his recruiting talents and recruiting customers."

"But, isn't it because he recruits so many people that the king of Wei dare not use him?" Zhao Zheng blinked his eyes and said straight away, "His purpose is to assist the country, but as the son of Wei, his reputation is better than that of the king of Wei." He is bigger and more capable than the king of Wei, how dare the king of Wei use him?"

"But if he doesn't recruit a lot of customers, others will not know his talent."

"Can virtuousness be proved by the number of followers?" Zhao Zheng said that what his great-grandfather said was completely wrong. There is no way to find out if there are thirty, and he has three thousand customers, can he recognize them all?"

"These people came to Mr. Wei because they admired his talents and hoped that he would recommend them to the king of Wei. However, there were so many people gathered around Mr. Wei that even a talented person could not recognize them. This delay is actually to let the The king of Wei can't find a talent? Where is the talent here?"

Yingji laughed loudly when he heard the words, and patted his thigh while laughing. After laughing, he said to Zhao Zheng mysteriously: "Zheng'er, do you know why there is no one from our state of Qin among the famous young masters?" share?"

Zhao Zheng's face immediately wrinkled, and he pouted, "Isn't there our Qin State?"

"No!" Yingji whispered, "But Zheng'er, don't worry, these sons are not good people, they are cancers to their respective countries."

"Aren't they good people?" Zhao Zheng was a little surprised. Although the names of the four sons of the Warring States Period had not yet appeared, as individuals, the names of the sons of these countries had already appeared.

"It's not good or bad, but the purpose of these people is to assist the country and maintain power." Ying Ji smiled, "In addition to assisting the country, they also want to maintain power. So it's not that they don't want to recommend talents, but the recommended talents must first If you are loyal to them, you will be recommended."

"Who would dare to use such a talent?"

"And the reason why the Qin State doesn't have such a son..." He showed a bit of arrogance, "It is because all the talents of the country belong to the king."

"Only talents, this is the foundation of Qin's power."

Qin State itself is a barbaric tribe, and the reason why it can grow stronger step by step is because it absorbs talents from all over the world.Therefore, there is a whole set of recommendation mechanism in Qin State, and what the old Qin people welcome most is the mutual recommendation between talents.

This is because the first rise of the Qin State was due to the foreign talent Baili Xi and his friend Uncle Jian.After being discovered by Duke Mu, Bailixi recommended his friend Uncle Jian to Duke Mu, and said that he was not as good as this friend at all. Such a selfless act won the respect and trust of Duke Mu.

After that, Baili Xi and Jian Shu brought the then weak state of Qin from a small border country to the Spring and Autumn Five Hegemons.Affected by this, until now more than 400 years later, Qin still respects such talents who are willing to recommend talents, especially those who are more talented than themselves. They think that such people are extremely tolerant in their hearts.

The kings of all dynasties never forgot to reward the recommenders while adopting talents. Therefore, it is impossible for Qin to have a son to recruit talents, because all the talents were snatched away by the kings.

And although the courtiers also have supporters, because the Qin State has a system in which those who are recommended are great talents and the recommenders are treated kindly, the courtiers are also willing to recommend upwards after discovering talents.At the same time, for the recommendees, they are also very clear that they and the recommender are cooperating with each other, and the object of their real gratitude is the King of Qin, not the recommender.

Although it was inconspicuous at the beginning, Qin State relied on this difference to hold the talents of the whole country in its hands little by little.And those countries with various "sages" and various "sons"... How many of them really benefited from the recommendation of these young men?

Ying Ji stroked the little head of his grandson who had realized something, and suddenly felt that he wanted to meet Lu Xiaolang a little bit.

Although they have been friends with each other for a long time...but they really have never met.

And what was Lu Xiaoan doing who was missed by King Qin at this time?He is introducing a new gadget that he has just researched-the vernier caliper with his new friends.

In the process of manufacturing waterwheels and windmills, there is one difficulty that cannot be avoided, that is, the extremely tight pipes.

In Qin Dynasty, the pottery pipe technology was very developed. Under the Xianyang Palace, there is a complex but perfect underground pipe group, which can ensure the smooth discharge of domestic sewage in the palace.

However, there is no way to use pottery pipes for the water suction pipes of windmills, because the pottery pipes are too heavy, and the layers of their own weight will cause the lower pipes to be crushed.It is not that the craftsmen did not think of a way to share its own weight, but in the end they all gave up for various reasons. The current windmill uses bamboo pipes.

But bamboo is a raw material that grows naturally, which determines their characteristics of varying thickness. It becomes a difficult problem to find bamboos with similar outer diameters among them.

Caliper was created by Lu An because of this need.

As the name suggests, its usage is to measure the outer diameter by clamping the object with two clips, and then read the pointer, which is much faster than the cloth strip measurement method originally adopted by craftsmen, with less error and more convenient to read the data.

However, the most important thing about the pipe is the inner diameter, so the caliper is slightly modified and the needle is reversed to measure the inner diameter.

The caliper that was made was snatched away before he finished talking about how to use it. After Lu Xiaoan got a loving touch from his father, his father used it up and threw it away.What else can Lu An do?Of course I can only forgive him!

Lu An, who had nothing to do and could only wander around, thought of combining the calipers that can measure the outer diameter and inner diameter into one, so there is no need to carry two rulers.So he went to find a metallurgist who had nothing to do for the time being, and a few people made the vernier caliper with a lot of effort, and also added a function that can measure the depth, which is really great!

About why a vernier scale is added at the bottom, why the scale is divided into ten, why there are only nine vernier scales, and there is a conversion process to get the answer, etc., Lu An himself does not know why, anyway, he is just discussing with others like this After discussing it, it was discussed.

This must be the power of the collective!

In order to thank the child for having an idea to create a tool that can solve the troubles of the craftsmen, and to share it openly, several craftsmen made a caliper together and gave it to Lu Xiaoan.

The master's moves are naturally extraordinary. The ruler in Lu Xiaoan's hand is top-notch in terms of raw materials and accuracy, but it is also because of this... After taking it home, this caliper was collected by Lu Buwei, and Lu Buwei even brought it with him. He took the gift and his son to thank those craftsmen.

This ruler is now on the verge of being placed in the family temple as a family heirloom of the Lu family.Of course, the reason why they haven't been treated like this is because the Lu family's family temple is not in Xianyang.

Because things are too expensive, even Lu Xiaoan can't take them casually. What he is showing this new friend now is a normal version of the vernier that he asked craftsmen to make.

Lu An's new friend was a water worker who was recommended by a county below the state of Qin. His name was Li Bing. The two met on the other side of the Jing River.At that time, Lu An was taking his senior brother to watch Lu Xiaoan's labor achievement - the operation of the windmill. When Lu An was explaining the operation principle of the windmill to Wei Liao, Li Bing suddenly interrupted and asked about the windmill's sediment disposal. acquaintance.

It's a pity that the windmill is very simple and crude in dealing with the silt carried by the Jinghe River, and it is just a filter.After hearing this answer, Li Bing was a little disappointed.

It may be because of the attractiveness of the male who is also an engineering major. Lu An immediately fell in love with this young man when he first saw him.After the two chatted, they learned that Li Bing was originally from the state of Shu, a subsidiary state of Qin.However, in the sixth year of the King of Qin, Ying Hui, the son of the Qin Kingdom, was exiled to the Kingdom of Shu by King Zhaoxiang because he refused to obey the discipline and was stubborn. For Shu County.

It was in this battle that Li Bing's father was killed in the chaos, and his mother fled to Qin with his mother protecting him.The mother and son wandered away for several years, because the Qin State spent great efforts to reorganize the Shu State and blocked the entry of the population, until Li Bing's mother died of illness and could not return to Shu.

Li Bing was still young when he left, and he did not return to his hometown until decades later, but his branch had fled scattered during the war.His mother told him where his house was, and he had already moved into another family.Fortunately, he has an open-minded personality. After learning that his uncle's family was gone, he simply took his mother's tablet and wandered around the country, trying to remember the scenery of his hometown.This walk leads to the location of the Minjiang River.

The reason why Qin State wanted to lay down the Shu land was because the Shu State surrounded by mountains had a precious plain area, where the climate was warm and humid, suitable for growing food.

The old Qin people who are almost all mountainous in the country still want to build Shu into their own big granary, but they don't know that because of the existence of the Minjiang River, the people in Bashu suffer from waterlogging. Difficult to be fertile.

Therefore, the Minjiang River has become a place that the local people both fear and hate. When Li Bing came here, he happened to meet the local people who believed the local witch Zhu's words and married the god of the river.

"The river god married a wife?" Lu An asked suspiciously.

"It's a living sacrifice." Wei Liao softly explained to him, "It's just a nice name."

"How is this possible?" Lu An's eyebrows were immediately knotted, "Do the local county officials not care?"

Li Bing coughed lightly, interrupting the child's indignation, "That woman is currently killing his wife."

"Oh--"

Heroes save the beauty, understand!

Li Bing tried his best to ignore the child's suddenly gossiping eyes and continued: "But as long as the floods continue, such witches will be indispensable. Bing can save one person, but not everyone, so since then Bing has wandered around in various places wanting to learn. The method of controlling floods is ultimately a small achievement."

"There is only one problem that is still difficult to solve, and that is the method of sand control."

"I see that the trouble of the Min River is not in the water, but in the sand."

The riverside is not a place to talk, so Lu An invited people to his house as a guest, and handed the sand table used for the project to this new friend as a demonstration.

Li Bing adapted well to the sand table. He used the sand as a painting to draw a rough topographic map, and pinched a few sand dunes.Take a tree branch and show it to the two, "The Minjiang River rushes into the middle of Sichuan from high to low. It settles here and raises the river bed."

He pulled it twice with a tree branch, and raised another small mound on the edge of a mound symbolizing Yulei Mountain, "Every year, every month, this place becomes more and more congested. During the rainy season, the river is blocked and all flow backwards." Enter Sichuan."

"It seems simple to break this situation, you only need to dig through Yulei Mountain, but..."

Lu An understood what he meant, "Brother Li is worried, but the sand will still accumulate here?"

"good."

Li Bing nodded, "It's easy to dig a hole in Yulei, but the river has a large amount of water, so it's inevitable that it will collide with the complete part of Yulei. As long as there is a collision, there will be sediment accumulation here. It will only take a few years, and the sediment will naturally form a dam, blocking the river from passing through." Come out from the jade barrier."

"If you don't control the sand and only control the river, it's just treating the symptoms and not the root cause." Li Bing shook his head, that's why he came to participate in this event. It's a pity that there is no income yet.

Lu An observed the terrain picture and suddenly asked: "The east of Yulei Mountain is..."

"Farmland." Li Bing knew exactly what he was thinking, and shook his head first, "No, if the Yulei Mountain pass is too wide and the water is too strong, the east bank will not be able to bear it, and the east bank is also a plain. Sediment will still accumulate afterwards."

Then it is impossible to wash sand with water by opening mountains.

The problem Li Bing encountered now was that the Minjiang River would inevitably form a vortex because it collided with Yulei Mountain. The sediment would be deposited at the bottom of the vortex and the clear water in the upper part would be discharged along the hole in Yulei Mountain.

that……

"If you want to speed up the formation of the vortex..." He thought for a while, "Ann has an idea, please take a look at Brother Li."

Lu An took out his small model windmill while talking, and asked his brother to shake the hand joystick to make the windmill spin. When the speed was fast enough, he slowly poured a glass of clear water towards the windmill. After being ejected, he pointed to the wind lane: "If this is a whirlpool—" he pointed to the tea, "This is sand and gravel."

"Then the vortex is fast enough, can it throw out the newly poured sediment first?"

Then, Lu Xiaoan looked at Li Bing obediently with a face of "I'm just talking casually, I don't know if it will work."
