This is to control, and in the same way, the pace of the development of the Ryukyu Navy is not so eager, and the Navy has such and such shortcomings, but the existing area is enough, and there is no need to start the Ryukyu Project.

In the past few months, these people who went to the island in the early stage really suffered a lot.

In the early stage, the transportation was unstable, and even sometimes, because of wind and waves or accidents, they would face the threat of not being able to replenish food for a day or two, or even several days, at night, and the hunters had to go out every day to hunt game to replenish their needs, and even in some cases, they had to do most of it.

Later, the transportation capacity was stabilized, especially the emergence of some convenience foods, after reducing the weight, the food was guaranteed, but because the personnel did not increase, the tonnage of the supply was reduced, and the materials were given.

The latter is important, but under the premise that there is no way to complete the demand locally, the transportation of construction materials will be dead.

A fortress more than 20 meters high, based on the area of 2,000 square meters on the first floor, probably weighs about 30,000 tons.

In later generations, that is, a few 10,000-ton ships could be sent, but in this era, there are many ships.

The Ryukyus and the Dinghai Navy are separated by thousands of miles, and under the premise of ensuring safety, they can only rely on a few ships to transport, and these ships, slowly transported up, at one time, that is, one or two hundred tons, even if it is four ships, an average of once a week, from the start of this project to the present, it is only a dozen times, and the total number is three or four thousand tons.

This number, even one-tenth of the fortress can not reach, if you want to save, you must burn bricks locally, technology does not become any problem, red bricks since the appearance, has reached a considerable extent, with the help of manpower, reached the limit, but there is no way.

Here, even open fires are strictly restricted, and at night, there will be special outposts to protect the safety here, and the smoke and fire are strictly controlled.

After all, there are only a few hundred of them, and they are still shouldering the task of pioneering, and if they do not attract the attention of the natives, they will not be triggered, and they are far from the point of complete development.

Because of the lack of transportation capacity, there was no way to build the fortress, but a part of the cement and steel were transported, which was already the limit of the navy, and this part of the materials was also strictly used for the construction of settlements.

These steels are not the simplest kind, but have been specially selected, and the current buildings of the Navy are divided into high-rise buildings, which can build up to 13-story buildings, multi-storey buildings, about 6 or 7 floors, and ordinary two-story small buildings.

In the middle, because of the emergence of the steel mill, the steel technology of the entire Dinghai Navy has developed to a considerable extent, and high-quality steel has continued to appear, and steel buildings have also been built.

Steel structures, compared to ordinary houses, have a huge advantage, that is, faster construction.

With steel as the skeleton, the weight is heavier than that of ordinary buildings, but there is no need to consider the speed of cement condensation, to put it bluntly, the entire steel structure house, all their stress points, are on the steel, filled around, just the wall, as long as a few days of construction, the cement dries out, this residence can be moved in.

Considering the military use of these buildings, the outer walls must be built with high-grade cement and at least four layers of bricks to ensure the strength of his defense, but some internal structures can be saved.

With the theme of steel structure, the combination of steel, built the skeleton, and then used cement and stone to combine to build the first wave of the camp, from the beginning of construction, to the completion of the construction, it took only 20 days, which is still waiting for materials, a total of about 1,200 tons of various materials were used.

Because of the height, the whole building is 15 meters, but not 5 floors, but 3 floors, the steel structure can not build too many layers, in the Dinghai Navy, four floors is already the limit, but unfortunately there are not enough personnel and equipment, simply built three floors.

Fortunately, there are a large number of combined beds, up to 3 floors, 4 floors of high and low beds, 5 meters of floor height and 3 meters of floor height, the capacity of the personnel is not much different, but the difficulty of construction is much simpler.

A three-story building, but with a capacity of more than 400 people, it is finally out of the original tent life.

You know, in the beginning, it was completely in tents, every day, at least 50 people, had to be on duty at night, and the tents were cooperated with some other things, mainly barbed wire, so as to be able to play a sufficient early warning role.

However, tents are always no match for walls, and a knife can cut through tents, but for buildings, especially reinforced concrete buildings, it is difficult to break them with a punching car.

It's not a fortress, and for the convenience of living, it's not completely sealed like a fortress, and most of the rooms still have windows.

Fortunately, it is not fully opened, and every window has been treated and fixed with a large number of screws.

One by one, the big screws need to be fixed with many wrenches, even if you are familiar with the screws, it will take half a day to remove them with tools, not to mention that these natives don't know at all.

Each steel bar is the thickness of a wine glass, composed of high-carbon steel, very strong, not easy to destroy, even if there is a window, it is not easy for the enemy to attack in, in wartime, can be closed of three gates made of stainless steel, to ensure sufficient defense ability.

The building is the last line of defense, can not be used, or not used, after the construction of the building, there is a basic fulcrum, more is placed on the periphery.

On the periphery, the first defenses were built with barbed wire, which is a new product, which can be drawn into a protective strip through a wire drawing machine and can be pulled into a protection under the premise of having some simple wood.

This defensive structure, which itself emerged after the advent of automatic weapons and muskets, appeared in the 11th century, and although it did not go to the battlefield, it could protect the Longbows.

Under the premise of having special tools, it may be less than a stick of incense to be arranged, this time, perhaps in the previous Northern Song Dynasty, it is impossible to have such a long reaction time, but under the premise of having a telescope, let the reaction time, from a few kilometers, to more than ten or twenty kilometers, it can be arranged immediately after discovering the opponent.

Barbed wire, for the moving target, has a huge blocking effect, the power of the cavalry, is reflected in the speed, under the high speed, even a thin barbed wire, can become a sharp knife, cut everything.

With barbed wire, and with the help of heavy infantry, the time to stop the opponent can be greatly enhanced, in fact, in the abolition of the heavy cavalry fast horse rush into battle, the advantage of the heavy cavalry is reduced a lot, in the absence of speed, with the heavy infantry, itself is not dominant, plus the longbow is behind the back, the power is doubled.

This is also used here, no matter day and night, dense barbed wire will be arranged, a three-layer network, enough at night, to avoid being attacked by people to the nearest place, to give the defenders time to react.

Next is the trap and the building itself, these three-dimensional defenses are enough to withstand the attack of 10 times the regular army, not to mention the natives.

Unprotected, using only the simplest weapons, not even iron, the natives could not gnaw at all, armed to the teeth of the defenders.

Before winning, first defeat, this is what the Dinghai Navy is best at, and it has been a tradition since the Battle of Baozhou.

Zhao Xin may not be able to help the navy a lot in terms of attack, but the equipment that can be given and all kinds of auxiliary materials have been mechanical, and he always believes that giving soldiers enough protection and covering them with a layer of turtle shell is a combat effectiveness that can be improved.

With a stable base and the gradual expansion of the settlement, the defenders chose to explore outward.

Their first task is to build an impregnable settlement, and the second task is to establish a foothold here and figure out the surrounding situation.

At the beginning, under the premise that they could not even guarantee their own safety, they did not dare to move at all, until the safety performance was guaranteed, because of the relationship between the protection and the large-scale reduction of the number of soldiers responsible for security, they did not probe around.

However, the scope of the exploration is only limited to the vicinity of the basin, and the main purpose is to find out the specific extent of the basin, whether there are any signs of indigenous activities, and draw a more detailed map.

The basin represents the sanitation of the mountain range, and in a specific place, the establishment of a defense point can include the entire basin and become a safe place.

After the initial stabilization, a team of about 50 people, divided into several groups, were sent to investigate, all of them were the best in the army, and they had also been trained in the ability to survive in the wild, and could go deep into the dense forest.

Except for some of the people who remained in the camp, who were still in charge of guarding the entire settlement, the rest of the people did not stop working.

On the premise of ensuring safety, continue to build the house and prepare for the large-scale entry in the future.

Now, because of the transportation capacity, it is impossible for the Dinghai Navy to send personnel on a large scale, but it has also made a promise that once the transportation capacity is satisfied, it will inevitably send personnel to the island on a large scale, and at that time, it will gradually become dense.

Their task is to build 4-6 more buildings in the current state, as well as a series of negotiated buildings, so that the entire settlement can accommodate more than 3,000 people.

At the same time as the large-scale construction of houses, the wharf was also repaired, and under the current poor conditions, it was impossible to dock large ships of more than 2,000 materials, at least, ships of 1,000 materials could dock.

On the premise that there is no wharf, and there is no mobile wharf, the previous transportation, more here, the use of small wooden boats to slowly load and unload.

In the camp, there are four rowing boats large enough to accommodate 12 people, and such boats, in the past few months, have completed all the loading and unloading and replenishment.

Such a small wooden boat, above the sea, is very dangerous, and at the same time the efficiency is quite low, only the dock, even if it is docked, is enough to solve the problem.

At present, the Dinghai Navy has rented a large piece of land near Quanzhou for the construction of warehouses and wharves, and when the time comes, the sea ships from the Dinghai Navy can be loaded and unloaded directly here, transshipment, and then replaced by sailboats of about 1000 materials, and enter the Taiwan Strait.

Perhaps, a ship of 1000 materials is not as resistant to wind and waves as a large ship, but it can directly enter the port, and the loading and unloading speed of docking is not in the open sea, and a little turnover can be compared.

The development of the Ryukyus, I am afraid, is not even the beginning, but it is already all that the Dinghai Navy can do, and Zhao Xin has always paid attention to it, which will become the basis for the expansion of the Dinghai Navy and the basis for take-off.

In fact, when the Ryukyus were first developed, Zhao Xin's idea was quite radical, and such a huge island had to play a role.

However, the vanguard went to the island, encountered countless problems in the middle, especially because of the wind and waves, causing a transport ship to be delayed for 7 days before going to the island, according to calculations, the food on the island has been cut off for 5 days, if it was not for the person in charge at the time, seeing the weather conditions, he made a decision immediately, and took the risk to send a hunting team of 200 people, in the basin, hunted a large amount of game, it was really troublesome.

This is still under the premise that the natives did not attack, at this time, if the natives attacked, not to mention combat attrition, non-combat attrition, it would cause heavy losses to the Ding Navy.

The establishment of the settlement made Zhao Xin realize the difficulty of stationing on an island in an era when science and technology were not developed.

It's not like Pirate Island, it's very close to the Dinghai Navy. Where is the Ryukyus, the distance from the Dinghai, the distance is about 1,000 kilometers, which has raised a lot of requirements for transportation, and the control of time must also be quite accurate.

Cement, steel, these need to be transported in the Dinghai Navy, can be transported to Quanzhou through other bulk commodities, and then transshipment, which will be a lot more convenient.

However, the Taiwan Strait is at least 200 kilometers wide, which is not a small problem for sea ships in this era, and Chinese-style sailing ships, if they want to go deep into the ocean, only large ships with more than 3,000 materials can ensure safety.

After deducting food, every month, the supplies that the navy can transport to the island are about 1,000 tons, and 1,000 tons of construction materials are nothing.

Especially after that delay, Zhao Xin fully realized the important role of the margin, he had to leave enough margin to ensure safety, in each transportation, will be within the necessary range, give a margin of about 20%, to ensure that even if the materials are interrupted, you can successfully live for 10 days, with the supplement of some other food, it can reach more than half a month.

Under the premise of ensuring this, all kinds of materials were transported to the maximum extent, and with the efforts of hundreds of people, after stabilizing the camp, the scale of the camp began to gradually expand, and the settlement of the Ryukyus also had the ability to expand.
