Because these soldiers themselves have undergone rigorous training, although they have an agreement with the Han military, after about half a year, these soldiers will return to the barracks after they are familiar with life at sea, and during this period they will be responsible for the food, drink and salary of these soldiers.

True, the salaries of these soldiers were paid by the merchants from the other merchants, and after about half a year, when the soldiers had completed their training, they would leave their merchant ships, but even then the merchants had no complaints.

Because they know very well that in the case of the lack of sailors in the early stage, the speed of training sailors These soldiers are far faster than the speed of ordinary people learning because of their strict discipline, so they may be able to become a junior sailor in half a month to adapt to the ship, and with some old fishermen they recruited, there is no problem with sailing.

Then, when they were trading with Persia and other places, they could recruit some experienced old sailors from the Persian caravans, and the experience of these old sailors, these soldiers must learn quickly.

After about two or three months, these soldiers are definitely excellent sailors, and these soldiers do not occupy all their sailor quotas, at this time they hire half of their new recruits to be trained by these soldiers, and when these soldiers leave, these newcomers should have no problem becoming skilled sailors, and with the old sailors who have become the backbone, they can continue to recruit sailors.

At that time, their caravans may be able to continue to expand.

This is one of them, and the second is that these soldiers have strong combat effectiveness, and they are allowed to be equipped with weapons, which means that when they encounter danger, these soldiers are their greatest protectors, and these businessmen will naturally not be stingy with this salary, just kidding, how long is the price of this ship enough to pay the salary?

Moreover, in a trade, the ship must be loaded with a large number of goods and goods, which are of great value, and these goods are worth many times more than salaries.

However, the number of soldiers they got was naturally not as large as Zhao Qi, and one of the reasons was naturally because they were almost all merchant ships, and only the Blackwater Trading House had two merchant ships at the same time, so this Blackwater Trading House was also the object of discussion among all merchants recently.

It's just that they have been looking for a long time but they don't know who this Blackwater Trading House is, as if it came out of thin air, and they won't inquire if they can't inquire about these merchants, in their opinion, anyway, this Blackwater Trading House will not be able to deal with them in the future.

How can there be a business company that is completely self-proclaimed, so sooner or later they can talk, but they don't know which company is behind it, some of them are speculating, this Heishui trading house is afraid that there are some big families behind it?

For example, the families of those emerging officials in the Han Dynasty now? I can't blame these businessmen for thinking too much, it's just that most people aren't like this, and this world is run by such rules.

But when it's time to extract the merchant ship, this Blackwater Merchant House should always appear, right?

But in the end, they were disappointed, because the merchant ship this product can not be received by everyone together, they are all accepted separately, as the first "customer" of the Dahan Dockyard Manufacturing Bank, Zhao Qi and they are naturally the first to take over, two merchant ships, each merchant ship has a total of 10 engineers, these 10 engineers in order to solve the problem they don't understand.

In addition, these engineers are naturally also to record the operation of merchant ships, after all, these merchant ships have been calculated and tested countless times, especially through full-scale models and similar simulation navigation and other technologies, which are built in the laboratory environment, although it is impossible for ships to fully simulate the marine environment.

However, some basic problems can still be found, but when the ship is actually launched into the sea for sea trials, many problems are impossible to completely eliminate, and some of the hypothetical designs, they also have to consider subsequent improvements.

Therefore, after each merchant ship is received by the customer, they can conduct tests in the nearby waters for half a month, first, to familiarize them with the ship, secondly, to find some problems, so that engineers can record or improve, and thirdly, to see if they can find some problems that need to be improved.

According to the standards of later generations, each vessel is handed over to the customer after sea trials to confirm that there are no problems, and during the construction process, the owner will send a monitoring team of professionals to supervise the entire construction process of the vessel.

But in this world, these problems do not exist, this is the first time the big girl sits in a sedan chair, so what rules are up to the big man, but it doesn't mean that they will be done like this in the future, and these things must be improved.

After receiving the ship, Zhao Qi and the others were all excited and went to sea directly, and the necessary materials on the ship Zhao Qi and they had already purchased in advance, but the first batch of supplies was not prepared too much, just enough for about three hundred people on each ship to eat and drink food and fresh water for about a month.

Then they began to go to sea, but many of the things that went to sea were not so simple, they simply stayed in the harbor for three days, and they did nothing during these three days, just training one thing...... That's how to raise and lower the sails, and the different sails are introduced by those engineers and recorded by the people in charge of this part.

In addition, there are observers and others who have to board the mast, and each ship is equipped with a large number of telescopes. Of course, these were all purchased by Zhao Qi himself.

It wasn't until three days later, when everyone could skillfully raise and lower the sails, that they officially left the harbor and officially began to leave the harbor, and after leaving the harbor, Zhao Qi and all of them began to enter high-intensity training, including Liu Heima, everyone was a little nervous.

The reason is very simple, only when you really start to operate this huge ship that can be called a giant in this era, you will know how many problems there are, many positions have to do their own duties, when they first go to sea, many people are obviously in a hurry, until two days later, it is slightly better.

After getting acquainted with the ship, Liu Heima and the others were a little surprised to find that this ship could really move against the wind, which ...... It seemed to them to be completely unimaginable, and they knew that the sail had not been used, but how could it be?

They couldn't help but think of the effects of the forces that Mr. Wu talked about when they were listening to the lecture, as well as the different directions, and what eddies were formed by the flow of air, and so on, they couldn't remember everything, but at this moment, the facts were here, and with the lessons they had listened to, they immediately understood some of the principles that this ship could move against the wind.

If they fishermen didn't care about what Wu Min told about swimming, who had just learned it for a long time, in their opinion, how could this gentleman, who had never seen the sea before, understand what a sea boat was?

But at this moment, Wu Min is shocked in their hearts, this Mr. Wu really understands, it seems that these knowledgeable gentlemen are really powerful, much more powerful than them.

With such a foundation, these old fishermen are naturally very in awe of these engineers, and the communication between the two sides is smoother, to be honest, these engineers are really completely complete to learn aerodynamics, fluid mechanics, ship design and other disciplines, and Wu Min is only a part of it.

There is also enough patience for these old fishermen and engineers, because although these fishermen do not know technology, they have inherited countless years of experience, and these experiences can be transformed into some technical problems in their hearts in an instant.

Some of the principles that these fishermen say, they just know that they can achieve such an effect, but these engineers know how these things are formed, what the principles of the phenomena they are talking about, and record these things, which are excellent references for the design of other boats in the future.

Not to mention anything else, the necessary rat rings on the anchors and cables, if someone hadn't reminded them, it would be difficult for them to think of it.

Rats may not think anything on land, but if they get on the ship, it is a huge hazard, it will invade the grain, fresh water, vegetables, etc. stored on the ship every day, in addition to spreading diseases in the confined space of the ship, in addition, they may also cause great harm to the ship's barn wall.

Some of the watertight cabins were a threat to the entire ship if they were damaged by rats, so it was a tradition that they still had two cats on the ship after it sailed, although they had made enough preparations.

The two cats were given to them by the shipyard, two for each ship, and the shipyard would also give them two cats when other people received the boat in the future.

In fact, when the ships of the Blackwater Trading House went to sea, other merchants also began to receive their ships one after another, but they had the same problem as the Blackwater Trading Company, all of them were the first time that the big girl got on the sedan chair, and they were even more unbearable, so they were all practicing how to raise and lower the sails in the harbor, and it even took much longer than Zhao Qi and them.

Soon another half a month passed in the blink of an eye, and in this half a month, Zhao Qi and they had left the coast for nearly a hundred kilometers or so, and they had now learned the use of navigation equipment such as sextants, in addition, such as the personnel used for observation, as well as the steam-type freshwater purification device on the ship, they had also learned to use it.
