The name "ship" originally means "ship with wheels" and "ship with wheels".

Historically, during the period of the Northern and Southern Dynasties, there were already paddle steamers, because of their characteristics of wheels, they were also called "car ships".

In the Tang Dynasty, there were cars and ships with two or more wheels on both sides of the hull, and in the Song Dynasty, there were even three-story high, building ships that could accommodate thousands of people, which were also driven by paddle wheels.

At the beginning of the 19th century, the earliest steam ship in Europe with practical significance also used paddle wheels as the driving component.

Later, the "propeller", a spiral thruster composed of several blades, was improved, because it was more stable, did not come out of the water in bumps, and was less prone to damage and lower cost than the paddle wheel, which replaced the paddle wheel.

However, due to customary reasons, later generations still referred to steamships as "steamships".

Of course, now the steamship of the Chu State is neither a steam ship nor a real gas ship, but a ...... Human-powered boats!

It is similar to the cars and ships of the Song and Ming dynasties, mainly relying on pedals, and in terms of improvement, it is the technology of the Chu State, such as rollers, rollers, levers, etc., with unique design and excellent craftsmanship.

In addition, there are more beast cages and input ports for true qi energy supply - there is no storage equipment for large true qi machines, but the warriors on the ship can input true qi into it in real time.

As for the "animal cage", it is similar to a large hamster wheel, and livestock such as cows, horses, and donkeys can walk or run in it for energy.

It can't be used as the main driving force, and the experimental nature is mostly good, but it's better than nothing.

After all, whether it is manpower or animal power, although the efficiency is much higher than that of the paddle, in the final analysis, the "creatures" that need to supply energy are also on the ship, and the improvement of efficiency is very limited - if you need more strength for a cow, you must really bear the weight of a cow and its feed.

Only by using the True Qi machine with a large amount of True Qi stored as the power can it be regarded as an essential improvement in efficiency!

However, this kind of river boat, Chu State has also made some, after all, the craftsmanship of craftsmen also needs to be polished, which can be regarded as the "pre-process" of real gas ships.

It is really necessary to use the section of the river, and try to lay the tracks, as well as the "rail bikes" that fit with the tracks, and the rail bikes can be used for fiber pulling, that is, they can hang ropes and pull boats.

Especially in the section of the river that requires a slender man to work in the calf, or even from the waist down, try to build auxiliary bridges to pave the tracks.

It not only improves the efficiency of fiber pulling, saves the manpower that is competing with water, but also improves the working environment of the slender man.

In essence, it is still relying on manpower, which is better than nothing +1.

In addition, Huang Yueying also designed a "water conservancy fiber" structure, which can build a waterwheel near the shore, and the power of the waterwheel, through the transmission of gears and chains, will be used on the "moped" driving on special tracks, which is more labor-saving when riding.

It can be regarded as further reducing the burden on the slender man......

It's just that because a large piece of flat land is needed, and in the area with this kind of waterfront, most of the water is not too urgent, and the role of the natural slender man is relatively small, so it ...... It can only be said that talk is better than nothing.

All kinds of "better than nothing" add up, and in the absence of the application of the essential innovative technology of "true gas engine", the transportation efficiency of the Three Gorges has also been nearly doubled.

Although as soon as the True Qi Machine appeared, the increase of several times could completely cover these "bells and whistles" innovations, Bai Tu still supported it.

The first is to encourage innovation, and the second is to ...... It is also for craftsmen to accumulate technical experience!

Also in Wudang County, even if there is no large-scale real qi machine now, manpower version cranes, excavators and other tools have been made on site.

Just wait for the "Pan True Qi Plan" to be harvested, and the productivity of Chu State will progress by leaps and bounds - because the scientific and technological points in the mechanism have already been ordered.

Moreover, at this time, the auxiliary transportation project of the Three Gorges is more important...... I don't know how to do it!

Looking at the "slender man" on the shore who was pedaling on a strange two-wheeled vehicle, looking at the boats without sails, and looking at the waterwheels, Qin Mi fell into "unclear consciousness".

Because the Chu army, who was just passing by and seeing a few glances, would not give him the opportunity to stop and observe carefully, let alone answer superfluous questions, so it was in Qin Mi's heart...... Even if he was told that the transportation efficiency had increased tenfold, he would believe it!

Although Qin Mi didn't know how effective these projects would be, Qin Mi, as a qualified official, could at least estimate the cost of these projects.

The high auxiliary bridges along the coast, the boats that look complicated to work, and the huge watermills......

If he is asked to supervise the construction and manufacturing, I am afraid that it will be a small project, and these are just to make the transportation more convenient, then ...... The effect must far exceed its construction cost!

Therefore, according to Qin Mi's speculation, the increase should be at least five or seven or eight times, and even the anxiety in his heart was even more due to this-the Chu State had paid such a big price, would it be easy to stop the war? Is it really just for Zhang Lu's Hanninghou?

And if the transportation capacity is increased several times, the logistics supply pressure is much less, right? Maybe...... The reason why there was no increase in troops was just to let Yizhou relax its vigilance, in fact, the limit of the Chu State was far more than 20,000 people!

In fact, it is not surprising that there will be such a misunderstanding, because Qin Mi refers to Yizhou's construction capacity and Yizhou's labor costs.

Because of the problems of materials and technology, Yizhou's construction capacity is much lower than that of Chu State, so in Qin Mi's heart, he took a look at these constructions, but in fact, for Chu State, construction is not so difficult.

However, Yizhou has no workshops, relatively wars and fewer wars, and the labor cost is so low that the price of eating soil is so low that it is the price of eating soil - especially the government requisitioning labor, which is really the price of eating soil, and even the food money is not enough!

Therefore, Qin Mi would not understand how important it was for the Chu State to save the manpower of the slender man and the manpower of the laborer.

Now the manpower of Chu State is very "expensive", it is really a slender man in a bad area, and a month's salary can be worth a year's harvest of 100 acres of land!

It's not that Bai Tu spends more money, but after the rise of the workshop, manpower is naturally valuable - after all, the entire Chu State has a population of more than 12 million, and after the farming efficiency is improved and the workshop technology keeps up, the speed of urbanization has soared rapidly.

Although the rapid change represents an increase in troubles in all aspects, there are also many additional benefits that Bai Tu did not expect before......

For example, the part of the population hidden by the wealthy family of Jingyang has basically been census out.

After all, if you farm in the countryside, it is not easy for the imperial court to check, and to a certain extent, it is not willing to turn your face to check, but if you enter the workshop, you must have a household registration in the Chu State!

First, no matter how "trenched" the wealthy families are, they can't bear the soaring value of manpower, and there are still a large number of hidden households to inefficient farming, servants, and coolies.

It's just that compared with the court of Emperor Tiangao before, they believed in the wealthy families in the township more, and while the manpower was soaring, they were naturally willing to take the initiative to break away from the wealthy families and return to the position of Chu Min.

At the same time, wealthy families, or "workshop owners", a new group of wealthy families, who gradually turned to workshops as an important source of income, were keen to extradite displaced people......

The act of "catching slaves" was vigorously pressed by the Chu State, and the prohibition of slaves was originally one of the foundations of the Chu State, and this aspect could not be changed, but it was ...... The state of Chu welcomes people from all over the world to emigrate!

On the contrary, the imperial courts in the Central Plains and other places had to prohibit the circulation of the common people - this is completely different from the situation after the great development of the productive forces, when the population has overflowed.

Chu State, as long as you abide by the laws of Chu, everyone wants it!

Even if Bai Tu used trade as a bargaining chip, he could only ask the Wei State and the Han family to relax the immigration restrictions on imperial examination talents, but could not directly threaten the other party, lift all immigration restrictions, and let the people cross south, otherwise the other party would definitely turn his face every minute.

As a result, ordinary people in the Central Plains are unable to move on their own, but ...... But the wealthy families have their own channels!

Bai Tu also recently discovered why the influx of "displaced people from all over the country" is actually increasing, and it has not slowed down at all - the in-depth investigation of the Fengwei found that there are some Jingyangshi tribes, docking with the Central Plains, Guanzhong, and even the big clans in the north and Liaodong, and steadily trading a part of the population......

Some are hidden households and servants of big clans from other places, and some are ordinary people who want to move to Chu State, but lack a way!

The price of these manpower being moved to the Chu State, or the income of those scholars, is generally the ten-year contract signed with the big families who are connected with the country.

In addition, in order to "absorb displaced people", local government offices also have subsidies for displaced people, and they are included in the scope of official inspections, so if they can "get" displaced people, local government offices will also support and commend them, so this can be regarded as a joint effort between the government and the people......

These wealthy families do have their own wisdom, and Bai Tu didn't think of this before.

Bai Tu did not stop this, but focused on supervising the implementation of the "resettlement of displaced people", implementing the division of land according to households and the protection of the people who were already Chu people after moving in.

In particular, to prevent "isolation" behavior, no matter how you come to Chu State, since you are already a Chu Min, you will enjoy the treatment of Chu Min, and the legal ten-year contract is valid, but it is absolutely not allowed to attempt to "isolate and keep in captivity".

No matter how much strides are made, it is still far from the welfare society, the advantage of Chu is not welfare, but the opportunity for labor, and higher labor value, any labor force is lacking in Chu State.

As long as it is indeed in line with the ten-year contract of the "Law of Chu", and there is no forced enslavement or restriction of freedom, how did these people come about, Bai Tu doesn't care - it is also a headache for the princes who have lost the population!

Even so, in terms of manpower, Chu has always been "waiting to be fed", so naturally for Chu State, it is very cost-effective to build these auxiliary facilities and equipment to reduce manpower consumption by half.

Of course, the disadvantage of more expensive manpower is that the cost of the project of the Chu court has also increased dramatically.

Bai Tu did not specifically pay more for the requisitioned porters and other civilian workers, but only rejected the proposal of some officials to reduce the manpower quotation at the time of official requisition.

And Qin Mi still can't understand this kind of behavior at all......
