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

Taxation is the foundation of a country, the lifeblood of a country, and the foundation of supporting a country.

"Every change in taxation must be done with utmost care, and you can't be too cautious." Lu Xiaoan said with a serious face, "Compared to the precarious and overthrow of Wei State, which is only a matter of time, our Qin State's taxation is based on land property. , does not give tax exemptions to a specific single group of people, so it is very healthy."

"Great Qin is based on agriculture, and agriculture is based on water. This is because Li Bing, the governor of Shu County, handed over the plan for the second phase of the Guanjiang project. The Ministry of Industry has already made a model. I am here to invite you View."

That's right, what's the point, even if Lu Xiaoan has been off topic for a long time, it's only a matter of minutes before he gets back to the topic. Lu An spoke out his real purpose for coming here quite reservedly, which immediately attracted a series of questions from his younger brother. star eyes.

The first phase of the Guanjiang water conservancy project was very long, and most of its main work was spent on breaking rocks.Yulei Mountain, as a gap that must be broken, is difficult to overcome. Even if Li Bing borrowed a lot of hard tools from Chang'an, it would be difficult to break through the hard Shu stone.

For this reason, Li Bing visited many local quarrymen to learn the method of burning fire and stimulating water. First, he set fire to the stone, and then poured water on it to cool it down rapidly when the temperature was extremely high, so that the project did not continue to be delayed.

But even so, it took Li Bing seven years from the start of the construction to the completion of the construction. Frankly speaking, this figure is not satisfactory, especially when compared with the rapid progress of the canal.

But Li Bing was smart because he thought of another way to make money besides building hydraulic projects, that's right, mining well salt.

Qin State itself is not considered a country short of salt, but Qin State has precious human resources and weak industry and commerce. Therefore, Qin State's own salt industry mainly relies on imports.

The emergence of well salt in Shu County enabled Qin to be self-sufficient, and even sold to neighboring countries to earn foreign exchange.

The most important thing is that the quality of the salt in Shu County is very high, no less than that of sea salt.The labor in Bashu is cheap, even if the transportation cost is added, it is much lower than importing from Qi.

With this level of visible economic benefits, the ministers of the state of Qin have some tolerance for Li Bing.

Moreover, Li Bing has a huge advantage over Zheng Guo, who also built water conservancy projects, that is, he is the sheriff of Shu County in Shu State. As a sheriff, he has greater freedom in the construction of local water conservancy projects.

Therefore, although many people in the Qin State Central Committee have some opinions on the construction of Shu County, after investigation by Lu Buwei, they found that Li Bing's manufacturing rhythm was correct, and King Zhaoxiang of Qin trusted this one who was selected by him. The prefect of Shu County can keep Li Bing's rhythm stable.

Now, two years after the completion of the first phase of the project, Li Bing resubmitted the application for the second phase of the project.

Today's Dushuijian is no longer the small department when Lu Buwei was first established. After the completion of the two major projects, the status of the department has risen, and Lu Buwei has been promoted as the prince and Fu Ke to participate in the court. .

The original position of superintendent was inherited by his only son.

Of course, Lu An passed the examination route in a serious way. Qin Guo didn't like the idea of ​​passing on from father to son, and now the approval of the second phase of the Guanxiankou project was on his shoulders.

The reason why this reply has not been approved for a long time after arriving in Xianyang is because Li Bing's set of statements is too shocking.

It is written in the application that he intends to build a project that can divert water and a project that can automatically intercept the sand and gravel of the Minjiang River.

The former is nothing, the key is the latter.

According to his official document, he did not build dikes or dams, but threw sand and gravel out by the self-rotation of water flow.This kind of construction method is almost unheard of, and it caused an uproar after the document arrived at the Dushui Supervisor.

The discharge of silt at the Guanzhong Plain is different from that of the canals in the Guanzhong Plain. The Guanzhong Plain mainly discharges sediment, but it is only extremely small particles. The trouble is that there are too many.The Min River comes from the foot of the mountain, and what it carries are stones from the mountain. If it encounters heavy rain and floods, the size of the stones that it engulfs will be comparable to a calf. This is also the difficulty in building water conservancy in this area.

Regarding rock control, the first phase of the plan submitted by Li Bing was to use the hard Yulei Mountain to resist falling rocks, but after the river channel was completed, he found that it was not feasible. The river mouth they dug in Yulei Mountain was narrow, which is fine at ordinary times. In the rainy season, stones are too easy to block the mouth of the river. If it is too late to remove the stones, it will be blocked, and the river will flow back.

Under such circumstances, Li Bing said that the strength of the river itself and the obstacles of the terrain can be used to artificially create violent and regular tumbling of the water, and use this force to roll up boulders and throw them out of the river. The craftsmen really couldn't believe it.

The deputy supervisor and a group of craftsmen who provided references thought that this move was impossible, but Lu An felt that it was feasible after careful study. The opinions of the two parties disagreed, so Lu An made a decision and decided to use the water potential to build in Xianyang. A similar small project will be approved if feasible.

Li Bing drew the engineering drawings very clearly, and tried his best to explain the principles clearly, and Lu An himself had exchanged ideas on this aspect with him, so he probably knew the principles, so the construction of the experimental project was progressing quite smoothly.

In fact, what Lu An and others want to experiment is actually to prove whether the continuous flow of water hitting the wall will cause the circulation of the water channel, and if the flow velocity is high enough, can the sand and gravel be thrown out at a fixed position? Just a little bit.

This small dispute originating from the Dushui Supervisor soon developed into a major event in Shangda Shengting. All the civil and military officials who had been bored for a winter and did nothing to do nothing, and the Ying clan expressed their desire to watch. A thousand servants were sent for their ground-breaking experiments.

So when the ground thawed after the beginning of spring, the construction of this waterway project, which received a lot of attention, began.Today happened to be the completion of water diversion, and the first water experiment will be conducted. The loyal Lu An came to see his curious younger brother to watch the excitement. Who knew that he happened to meet his younger brother in class.

Lu Buwei's teaching time is not fixed, because he is still serving as the left prime minister of the Qin State. The original Qin State Prime Minister Fan Ju was named the right prime minister. Anyone with a discerning eye can see that this is a sign of the handover of prime minister power. Now it is just a transitional period. .

Fan Ju knew in his heart that the delivery was quite smooth, but the affairs of the Qin State were complicated, and no matter how smart Lu Buwei was, he couldn't do it overnight. Under his repeated entrustment, Fan Ju, who originally planned to resign, stayed as an old employee and brought new employees. Then help him familiarize himself with the operation of the entire country's affairs.

It was also Lu Buwei who took the time to teach Zhao Zheng today, but was bumped into by Lu An.

Zhao Zheng really wanted to see the situation of the canal, and felt that it was very rare for his husband to come to teach him that it was a rare opportunity to give up. He hesitated for a moment, and said to Lu An: "Brother, let's go another day."

"It's okay, let's go." Just when Lu An was about to agree, a stranger walked in from the outside, and he patted Zhao Zheng on the shoulder who stood up and saluted, "I have something important to discuss with my husband as a father, let me let you go." Half a day off."

A look of joy immediately appeared on the child's face, but before he was finished, he heard a stranger say: "But the holiday is the holiday, and the homework still needs to be done."

Lu Buwei continued at the right time: "I just told the prince about three of the five soldiers, and there are two remaining soldiers. The prince might as well think about the remaining two soldiers?"

Zhao Zheng's small face suddenly wrinkled, he thought for a while, and said to Lu Buwei: "Zheng would like to ask sir to give me a hint, what sir just said is the three soldiers of Qi Zhiwu, Wei Zhiwu, and Qin Zhirui. Judgment, martial arts are defeated by soldiers, and soldiers are defeated by sharp soldiers. Dare I ask you, is the second soldier that you didn't mention better than my Great Qin's tiger and wolf soldiers?"

Lu Buwei nodded with a smile, and Zhao Zheng's expression immediately turned serious. He didn't say anything more, but bowed and said, "Mr. Xie taught me, Zheng must think carefully." After speaking, he left with Lu An.

Looking at the voices of the two half-grown boys leaving from a distance, the other person's eyes lighted softly, "The relationship between Zheng'er and An'er is still so good, it's really good."

Lu Buwei didn't know what it meant for a while, he just cupped his hands and said: "Your son is stubborn, fortunately the prince forgives you."

"Hey, I don't like to hear what you say, sir." The other man waved his hand, "I watched An'er grow up, she is smart and capable, so why is she so stubborn, sir is too modest."

Yiren strode over to the place where his son was sitting just now and sat down. Seeing Lu Buwei's surprised expression, he smiled, "Sir, the student has a problem right now, and I want to ask you for advice."

Lu Buwei's face turned serious when he heard the words, and he bowed respectfully, "It is the duty of a minister to resolve doubts for the king, please speak."

The stranger asked him to sit down first, and then said: "The news came from the front that the Eastern Zhou Kingdom wants to unite the six countries to fight against Qin. This time, the widow wants to send troops to the Eastern Zhou Kingdom to break its alliance. Well……"

He pondered for a while, and said: "The widow has not considered it yet, I wonder if the master has any recommendations?"

Lu Buwei's back turned cold. After King Zhaoxiang destroyed the Western Zhou Kingdom, the Eastern Zhou Kingdom was already the last remnant of the Zhou royal family, and also the last line of incense, and Yiren obviously meant that he did not intend to keep this hidden danger.

Who is more suitable to attack?Now that the Qin State is resting and recuperating, none of the generals of the Manchu Kingdom is leading the army. The Eastern Zhou State is just a small country. The only obstacle is South Korea, which must be passed through on the way. In fact, anyone is suitable to go.

But the stranger said it in front of him, and he obviously meant only one thing - "I wish to go there."

Lu Buwei kowtowed in obeisance.

To destroy the Eastern Zhou Dynasty is to destroy the heir of the Zhou king and the sinner of the Great Zhou Dynasty.But as long as the Eastern Zhou Kingdom is destroyed, Qin will no longer have to worry about who will come to attack Qin under the order of the emperor, and no one will be able to order the world in this name to fight alone. Qin will not be afraid of those vassal states at all.

And the person who led the army to destroy the Eastern Zhou Dynasty was the one who destroyed the Zhou Dynasty. The previous one who took on this name was an unknown young general selected by King Zhaoxiang from the army camp, but now the stranger wants him to also take on the responsibility. this name.

It wasn't Bai Qi, it wasn't Wang He, it wasn't Meng Ao, it wasn't Qin's many generals, it was him, the left prime minister of Qin, Lu Buwei.

If he does it, what will increase is not the personal record of the general, but the record of Qin as a country.

This strategy, this strategy was actually made by his student who was quite weak in the past. Lu Buwei's face buried under his arms showed a smile of relief or helplessness. This throne can really change a person.

His student is no longer a different man from the prince, but a different man from the king of Qin.

-

Lu An didn't learn about the fact that Qin State was going to send troops, not from his father who was about to be the chief general, but from his senior brother.

Wei Liao also wanted to participate in this battle.As a war launched after the Qin State had been quiet for a long time, the young people who were eager to make military achievements rushed to the conscription office with great enthusiasm. During the conscription, priority was given to those who did not need to farm, so Wei Liao was selected.

Hearing the news that his senior brother was going to join the war, Lu An immediately raised a stone in his heart. Of course, he knew that it would be a matter of time. The state of Qin relied on military exploits, and even his father had military exploits and meritorious service to enter the imperial court.If Wei Liao wanted to stand out, he had to use military exploits as an inducement, but when this day really came, he should be worried or he would still be worried.

As soon as Lu An got the news, he went back to the house and took a box of things to Wei Liao's house, and then took out the same things.

Although the Dushuijian is a department in charge of water conservancy, it is also a place where craftsmen gather, and it is a leisure department.

When there are too many craftsmen, everyone will figure out some gadgets when they are free.Before that, Lu Buwei was still able to manage it, but after Lu An took over, he completely let go and made a lot of miscellaneous things, some of which are still useful in water conservancy, and some are completely useless.

He also set up a special reward fund in the Metropolitan Water Supervisor after the report, rewarding the best invention or the best improvement selected every six months, which greatly improved the work enthusiasm of the craftsmen.

Although there will inevitably be waste of materials in the process of invention, the main raw material for manufacturing today is copper. If it is broken, it will be thrown back for re-refining. started.

But some waste products are not all waste products, they can be used for other purposes with a little modification, and the breast protection mirror is one of them.

The standard armor of the Qin State is mainly leather armor. Leather armor made of various animal leathers is usually made into armor plates and then stacked in layers.Then paint its surface to waterproof and increase its durability while reducing its coefficient of friction.

Ordinary leather armor can effectively resist the stabbing of arrows, and leather armor made of rhinoceros hide and elephant hide can even completely defend against slightly inferior copper arrows.

However, it does not have a good defensive effect on spears, swords, and halberds, which were widely popular in the Warring States Period recently.After all, there are gaps between the leather armor, and the sharpness of the stabbing weapon can easily penetrate through these holes when it reaches the leather armor.

The heart mirror itself was originally used to make gears. Some craftsmen wanted to use gears made of copper to complete standardized production. After all, compared with wood that needs to be polished, copper is mainly made by casting. A template is poked back and forth on the clay to make a master to ensure uniform size. The idea is very good, but in the end because the quality of the copper mine in Qin State is too poor and there are too many impurities, it cannot meet the hardness required by the gear.

These gears were flattened by Lu An, and the surrounding sharp thorns were flattened, and two pieces were connected, one in front and one in the back, just to protect the most fragile and easily open heart position of the human body.

In addition to the protective mirror, Lu An also prepared some armor pieces for his brother.

These armor pieces have holes that can be tied inside the leather armor with ropes to enhance the local defense, and at the same time, they are flexible enough not to increase the load too much.

Wei Liao looked at the piece of armor in surprise, and heard his younger brother whisper, "Senior brother, don't look at this armor, it's harder than copper armor."

--This is impossible!

This was Wei Liao's first reaction, but then he thought that this was made by his junior brother, and there might be secret methods in it.

Of course there is a secret method, that is to change casting to forging.

The difference between the two is that casting is a one-piece molding and then slightly polished, while forging is formed by beating the blank after heating.

Prior to this, Qin's iron wares used the same casting method as bronze wares.It cannot be blamed that the old Qin people used the wrong method, but people at this time have lived in the Bronze Age for more than a thousand years, and they naturally did not expect that iron and copper need to use different continuous manufacturing methods.

Therefore, the ironware produced by the casting method is hard and brittle. Except for a very small number of meteorites that can be made into weapons, most ironware can only be used as the main material of farm tools and a substitute for copper.

The forged iron can precipitate impurities, and make its composition more uniform, increasing its hardness.

And the armor plate in Wei Liao's hands is the product of using this method to smelt iron.

"Although it's just a test product, the effect is very good after testing." Lu An enthusiastically recommended, "Why don't you give it a try, brother?"

Wei Liao smiled slightly and said, "No need, I believe in Junior Brother."

Lu Xiaoan, who was dazed by this smile, returned home, only feeling his cheeks were hot, but he was called away by Lu Buwei not long after he returned home. His father told him the bad news that he was going to lead the army, and then He looked at his son expectantly.

Lu An, who just sent all the stockpiles to the next door: ...
