Yan Dashao did not dream that he would become an extremely tacky golden and bronze boy in the future, and after the troops landed successfully, established a camp, and established a firm foothold, he led the fleet to the north to visit Ryukyu, he wanted to take Ryukyu and open the passage to Wajima.

There is no way, Wajima is close to us, and there is a lot of silver, so don't let this one flow with silver

Led two third-class battleships and twelve sixth-class cruisers, he left the main fleet of four fifth-class cruisers and as many as twenty-four sixth-class cruisers in Tainan, which was his foundation and could not be lost, and his rule was already in full swing after the victory over the Fujian Navy Division last year, and no one could challenge his position, and he could leave with confidence.

In addition to the combat ships, there are also two newly built "Yaksha-class" fast supply ships.

The Southeast Province began to build fifth-class ships!

This "Yaksha-class" fast supply ship is similar to a fifth-class cruiser, but they have removed the cumbersome bow and stern, and the hull is streamlined, which is very conducive to speed.

As supply ships, they had no holes in their hulls, no guns, only twelve six-pounder cannons on the open deck for protection, and a large amount of rice, noodles, salted meat, salted fish, dried vegetables, maintenance supplies, jugs, and coal!

In the middle of the ship there are two large chimneys, and below them is an evaporator, that is, the seawater is heated with lit coal, and distilled to obtain fresh water!

The fresh water obtained can be used to replenish the fleet, although it is not much, but it is precious, and as long as there is water, the fleet can support it.

Ancient voyages, limited to technology, fresh water is not easy to preserve, easy to smell and deteriorate, clean drinking water after a week becomes turbid, dirty and accompanied by a peculiar smell, the British deal with it by using beer (in the early days of the voyage, beer will also spoil), wine (will also spoil, but can be eaten, but the wine is more expensive, often enjoyed by officers), rum (stable quality, not easy to spoil) as water for the officers and soldiers to drink (the drunkards are really happy).

In fact, rum was only supplied to the British army in West India in 1655, and it took a hundred years to supply a large amount to the British army, and now this process can be accelerated a little, because the British also imported some rum by the way when importing sugar from the southeast province, but the amount is not large, after all, the mainland has eaten a lot of rum.

And Yan Changwu was really heartbroken in order to solve the problem of drinking water on the ship, he was reluctant to give his subordinates to drink rum that could be exchanged for a large amount of silver, so he used another method.

The first is to use cleaner water sources as the source of water on ships, which is not appropriate, and no matter how clean the water is, it cannot be stored for too long.

Second, he creatively used a water filter based on activated carbon!

Activated carbon is very useful, it is used to filter water to support the voyage of the fleet, and to turn brown sugar into white sugar when making sugar.

Yan Changwu has specially established an activated carbon plant to produce activated carbon by physical water vapor method, and its process is divided into two processes, the first step, carbonization, drying the raw materials at high temperatures, and carbonizing its 80%r organic tissue at the same time. The second step, activation, sends the carbonized material that has been carbonized in the first step into the reaction furnace, reacts with the activator and water vapor, completes its activation process, and makes a finished product.

In the process of endothermic reaction, the combined gas of CO and H2 is mainly generated, which is used to heat the carbonized material to an appropriate temperature (800 to 1000 degrees), remove all its decomposable substances, and produce a rich pore structure and a huge specific surface area, so that the activated carbon has a strong adsorption force. The activated carbon produced by different raw materials has different pore sizes, among which the pore size of activated carbon with coconut shell as raw material is the smallest, the pore size of wood activated carbon is generally larger, and the pore size of coal activated carbon is between the two.

The main production of coconut shell and coal activated carbon, its production process is strictly confidential, only the finished product is seen on the market, and where it is produced, how to produce it, let the spies of all parties sharpen their heads and can not find out the secrets, after all, the southeast government is a totalitarian regime, and the people are inspired, mobilized, there are Chaoyang aunts and police, secret agents to defend the death, for their own technology such as activated carbon production, sugar, gelatin and other technologies are very well protected.

Activated carbon water filter is a multi-layer water filtration, which is divided into screen, cotton, grit and activated carbon, etc., and is known as the filtered water that can be purified by soaking in urine.

In this way, with this water filter, the durability of the fleet can be increased considerably.

In addition to the fleet's use of water filters, the troops dispatched expeditions, exploration teams, expeditions, etc., all brought water filters to ensure that there was clean water to drink without heating.

It has to be said that drinking clean water is deeply rooted in the hearts of the people, and the people of Southeast Province rarely have dysentery and other digestive diseases.

The third method is to distill seawater!

The principle of distillation is very simple, that is, the seawater is boiled with coal, the fresh water is evaporated into steam, the salt is left at the bottom of the pot, and the steam is condensed into distilled water, that is, fresh water.

This ancient seawater desalination method consumes a lot of energy and produces a lot of pot scale, and it is difficult to produce fresh water in large quantities, and it cannot completely solve the problem of fresh water.

There is a great danger in boiling water on a wooden battleship, ordinary warships cannot do this, only on the specially designed supply ship, a large metal base is made into the hull, and there are a large number of heat sinks on the side of the metal shell (this technique is not difficult), and then a boiler is set up, and coal is used as fuel to boil water, and the water vapor enters the porcelain refrigeration condenser to form fresh water.

……

During the voyage, Yan Changwu ruthlessly let them train to fight guns, strictly train them to operate sails, anyway, the officers and men on the ship were turned around, he patrolled the battleship, and required the battleship to be clean and tidy at all times, after various training or exercises, once it was over, the deck must be wiped to be able to shine, and all the copper parts must be shiny.

The paint must be cleanly brushed, the sail pieces must be stretched and structured, the sail truss must be retracted at 90 degrees from the mast, there must be no debris on the mast, and the ropes must be stacked neatly, etc.

The speed of the cannon is always demanding, shouting "Faster, more accurate, better!" ”

Although the requirements are high, the officers and men on the ship are still full of energy, they are exhausted, but their enthusiasm is undiminished, mainly the sense of honor as a member of the flagship, and the 10% increase in salary!

Military discipline was clearly established that all "units" under the command of the Overseers would receive the honorary title of "Guard", and their members would receive a 10% increase in their salaries.

In addition, units that perform well, such as those who are brave in battle, can also be awarded the honorary title of "Guard", and their members can be paid an increase of 10% (not necessarily by the Overseer), and a special emblem may be added, and the title of "Guard" can only be obtained in battle, as a way to motivate officers and soldiers to fight hard.

What he does is not picky, but a strategy!

You must keep your subordinates busy, keep your army busy!

them like dead dogs, full of harvest, they will have a strong physique with excellent quality, as well as first-class combat skills, form a conditioned reflex when fighting, and do not blink an eye, so the chances of victory will increase.

The soldier is endlessly busy, mentally and physically exhausted, and as soon as he lies down in the hammock, he falls asleep, he has no mind to think about anything else, his mind is simple, and it is good for everyone!

No matter how strategically we have to get busy, what to do this year, what to do next year, such as occupying Taipei, the Marine Corps going ashore, the fleet can't just train, they give support to the Marine Corps, once the Marine Corps has a firm foothold, immediately set sail for the Ryukyu Islands!
