The biggest problem in the canal transportation yamen is not at all about the loss of canal soldiers and ships that Liu Mingqi mentioned.

It is about corruption and fire consumption.

After Miao Yan has been dealing with corruption, it will definitely rectify it well and will definitely improve for many years.

But as long as Miao Yan leaves, the successor is not as good as him, and he will be restored to his original state in two or three years.

This is inevitable in ancient and modern times, both in China and abroad.

The same is true for the fire consumption.

The fire consumption in the canal transportation yamen is very high, reaching about 1.8 times.

What does it mean?

If you want to transport a kilogram of grain from Jiangnan to the capital, you must prepare 1.8 kilograms of grain in Jiangnan.

If you want to transport it to the territory of the northwest garrison, you have to double the fire consumption.

So this almost doubled the loss greatly consumed food, making the annual birth of famine even more shocking.

But this is more troublesome than solving corruption that can be solved.

Why?

Do you think 1.8 times is very high?

That's really not high!

If you transport by land, it will cost five times the fire to the capital city, and ten times the fire to the northwest pass!

It means that you transport ten kilograms of grain from Jiangnan to the northwest pass, and in the end you can only get one kilogram.

have a look!

Compared with land transportation, do you dare to say that the canal transportation is not kind?

Liu Mingqi wants to spit on your face!

But the fire consumption of the canal transportation yamen is just a very special example. In fact, the entire Grand Canal transport fleet is treated the best and the least.

Because there are no dangers in intercepting the canal transporting money and grain fleets along the way.

But the fleets of ordinary merchants are not so lucky.

The taxes they encountered were two or three times less, and even seven or eight times less.

This involves a large amount of corruption, a large number of checkpoint personnel, and unreasonable taxes.

Don’t think that this matter is only in the Ming Dynasty, but in the Qing Dynasty, but in fact every dynasty has it.

Even great prosperity cannot be spared from the common people.

I believe this aspect is also the focus of Miao Yan's rectification.

Dakang was established by business. Everyone knows that only when the goods are circulated more can the price be cheaper.

If you increase the price layer by layer, even the cheapest thing will become very expensive.

In this regard, nobles and royal families took advantage.

Except for some formal large-scale tax and fee levels, they don’t have to pay the rest, and they dare not make things difficult for them.

Otherwise, if they get into trouble, they can't even keep their own position, so how can they make money?

Even those like King Yu who do not do business know that in addition to collecting money to operate the canal transport and paying taxes, there are at least two or three times the money, which is swallowed up by everyone in the middle.

But the court can't control much.

For example, as mentioned before, when the canal transportation yamen needs to repair the river channel and clean up the silt, the local government will pay for it.

How much money does local governments have?

They have no money, so they can only make money by setting up checkpoints on the Caoyuan River?

OK, you don’t want them to set up cards, and they are willing to do so.

But next time you clear and repair your work, don’t come to us.

No money!

No money even if you beat him to death!

Therefore, the court acquiesced to their behavior.

This is also impossible.

...

Fortunately, this matter can only be left to Miao Yan to worry about, and Liu Mingqi doesn't have to worry about it at all.

So look at it, being an official is so troubled, what kind of big trouble will you have when you are an emperor?

It is good to be an emperor like Jie of Xia, Zhou of Shang, Emperor Yang of Sui, Emperor Ming of Tang, Emperor Huizong of Song, and Emperor Qianlong of Qing Dynasty, but except for the old man Shiquan, who can have a good ending, everyone else can end well!

Poor to me, the Ming Dynasty, none of the dozen emperors were as crazy as theirs, but they were destroyed.

Zhengde, who was scolded the most, also killed himself to the grassland, defeating Altan Khan!

Looking back on the fate of these emperors, Liu Mingqi was already very satisfied with being an imperial prince who was indifferent.

Whoever dares to call me the emperor is my life and death enemy!

All right.

Come back to your eyes.

Of course, he couldn't do nothing.

Even if time travelers can resist being an emperor, they will not be able to prevent them from pretending to be compared.

The boy has a lot of talent, how can he be worthy of traveling through time without showing it?

He has been locked up at home these two days, constantly recalling the dredging ships he saw, constantly writing and drawing, and modifying the drawings.

Liu Mingqi is a science student, but her major is not a ship.

However, there was a ship factory next to the school he attended. When he went there for internship and observation, Liu Mingqi entered its showroom and saw many artworks used in ancient times.

Including "hunjianglong", "iron dragon claw", "junction of river rake", "driving mud and leading river dragon", "overturning mud and locking ships and forcing them to slip away", etc.

This "Dragon Driving the Mill and River Driving" is really real. It is made like a huge mouse, and has two eyes installed, which looks a bit like a mutated monster.

Liu Mingqi looked at their size and functional characteristics at that time. The total time was only three days, so of course I couldn't remember too much.

But for an engineering student, this is enough.

As long as you rely on the memory size, you can roughly create a drawing structure, and then craftsmen can actually create it and improve it while using it.

However, Liu Mingqi naturally did not have such comprehensiveness.

All he had to do was to do was two kinds of ship artwork.

In fact, "hunjiang dragon", "iron dragon claw", "drink river rake", "driving mud to lead river dragon", "overturning mud and locking ships to run away" and so on are all for dredging, which is to break the silt below the river surface so that they do not accumulate.

None of these ships have the function of salvaging the soil.

What is really useful are the modern "twist suction dredger", "rake suction dredger" and "chain bucket dredger".

After they dig directly, they used a high-power machine to draw out dozens of cubic meters of mud and sand in minutes.

If the largest ship comes, as long as it can operate, in less than a month, the silt and sand at the bottom of the entire Grand Canal will be cleared and the water level will drop directly twenty meters!!

pity!

Unfortunately, the most important thing is that these covetous big guys are not available now.

The main reason is the motivation problem.

If you don’t have strong kinetic energy, how can you create such a great attraction and pump up the shattered mud and sand?

Of course, from this condition, Liu Mingqi could not make large dredgers, but small dredgers that used artificial kinetic energy to replace machine kinetic energy can be thought of.

I divided the whole process into two parts, one of which was used to silt and crush the silted mud and sand, and the other part was specially used to dig dredge. Is that okay?

I don't even want your strong attraction, or the powerful force of turning and crushing the knife head.

As long as the effectiveness reaches the point where it can be extracted from mud and sand every time, it is a victory.

One boat is not enough. I have about ten ships to start working at the same time. I can always achieve good results, right?

In this way, it is much more convenient than waiting for the dry season every time, and using manual effort to dig and harvest mud and sand.

It also saves a lot of time and effort.

Once there is silt, dredging can be started immediately, so as not to wait until flood disasters come. Because the dredging is not timely, the water level will become higher and higher, thus directly destroying the embankment.

So the drawings made by Liu Mingqi are a dredging ship similar to the combination of "Huanjianglong" and "Iron Dragon Claw".

The main function of the dredging ship is to disperse and break down the deposited silt, making it easy to be adsorbed. Modern ones are integrated with dredging and dredging. In addition, it is powerful, so it is naturally much more convenient.

The remaining two are dredgers.

One is the "sucking dredger" that Americans often used in the 19th century.
