Hearing that Muse mentioned pirates, Renault asked curiously, "it''s said that there are many pirates active in the four major sea areas, among which there are five most powerful pirate groups. What are their origins?"

Muse immediately took over: "in the northern ice sea, the most powerful pirates are Tieguan pirates. It is said that they are deeply involved in the snow thorn Kingdom on the frozen land. Some people say that their supporters are the ice leaf Lord of the snow thorn kingdom."

"The bay sea area is the area where pirates are most frequent. There are no less than 10 famous pirates in this area. Among them, there are two most powerful pirates, one is the crazy shark pirate, and the other is the red skeleton pirate."

"According to the rumor, the two pirates seem to have reached an agreement to divide up the bay sea area. The former''s sphere of influence is in the north of the bay sea, while the latter occupies the south. The two sides are not allowed to cross the border easily."

"There are also two powerful pirate groups, black feather pirates and blood wolf pirates, near the southern Xinghai continent. They occupy the Xinglan sea area, but their conflicts are very big, and they often conflict with each other."

Renault could not help shaking his head.

The alien ocean has become a paradise for pirates. These five pirate groups have carved up the ocean. Do the navies of all human kingdoms eat shit?

However, there is also a possibility that this situation of rampant pirates may be the result of the deliberate connivance of the major kingdoms. There are black hands behind the Tieguan pirates. Are there no other pirate groups?

The more Renault thought about it, the more likely it was.

Nima, it''s very difficult for these noble people to see the extreme. Compared with the serious sea trade, of course, the speed of robbing money is faster.

On the one hand, they can manipulate pirate groups to attack their competitors and expand their trade share; on the other hand, they can buy goods plundered by pirates at a low price and sell them at a high price.

Even the nobles at the top of the society degenerate into this virtue. It''s really an apocalypse. No wonder the human world is coming to a dead end.

Renault recalled the chart and asked, "is the shark pirate nearest to the tide collar?"

Mu Si definitely nodded: "yes, I''ve heard some rumors, it''s said that crazy shark pirates have relations with black orcs..."

When he heard the word "black Orc", he became interested: "Oh? Can you be specific? "

"Some people have seen the sailboats of the mad shark pirates frequent in and out of the ports of the former Bell Kingdom, and occasionally the black orcs take their sailboats to other places. There is even a rumor that they help the black orcs train their sailors..." Muse said

Renault''s face changed slightly. These black bastards were really far sighted. It can be seen from this rumor that the black orcs obviously planned to cultivate their own navy.

It is estimated that once the black orcs have a large-scale Navy, it will be the time when they attack the three human kingdoms on the southern Xinghai continent.

And this time, 10 years at most!

In addition, from his clear and clear answers, we can see that he must have done a lot of homework during this period.

He had a hunch that sooner or later the territory would conflict with the pirates, so he spent a lot of time in advance to study and gather the pirates'' information.

This is enough to show that, as the highest officer in charge of military affairs in the territory, moss has done a very good job.

Two days later, Odin and Haichao arrived at Midway Island and stopped here for one hour to replenish nearly 100 tons of heavy oil and fresh water respectively. After that, the fleet set out again and did not even have lunch on the island.

The reason why the replenishment operation is so fast is that the warehouse in Midway Island uses a new technology - pipeline transportation.

Because it took half a day to unload the cargo at Midway Island for the first time, and the sailors who were responsible for carrying the cargo were tired, the Department of navigation proposed this targeted improvement.

To put it simply, it is to use the high-power "high-pressure magic oil pump" to transport the heavy oil to the destination through the pipeline, which can be delivered from the heavy oil depot of Midway Island to the sailboat, or pumped from the heavy oil tank of the sailboat to the heavy oil depot.

Magic oil pump technology is ready-made, there is no need to start from scratch.

The structure of magic pump in shipyard is slightly modified, so that it can be used for heavy oil with higher viscosity. After adjusting the blade structure and increasing the blade speed, a high-pressure oil pump is born.

Renault did not interfere in the development of the oil pump at all. After the Department of navigation submitted the demand to the Institute of rune, a group of Rune magicians worked hard for three or four days, and the new product development was completed.

There is no difficulty in oil pipelines.

Originally, the rune magicians planned to use metal tubes, but Renault did not hesitate to reject this plan.

In order to ensure enough conveying speed, the diameter of the pipe should not be too small. In this way, the weight of the metal pipe will be very heavy.

In addition, because the length of the oil pipeline is very long, the total length from the heavy oil tank of the sailboat to the heavy oil depot of the warehouse is more than 50 meters, so it is obviously unrealistic to make such a long metal pipe.Therefore, the metal pipe must be manufactured in sections, but this also brings a new problem - installation.

If there is a corner, there must be a special right angle connector.

More importantly, the precision of the fitting parts must be very high, so as to ensure the sealing of the connection position.

With the current manufacturing level in the territory, it''s impossible to handle such high-precision large-scale pipelines, and the Lord can only do it himself.

But Renault quit, MMP. We can''t find the master for everything. We are determined to fight against this "unhealthy trend".

Obviously there is a faster and more convenient solution. Why do you idiots have to connect with metal pipes?

Faced with an inquisitive group of magicians, Renault just dropped eight words - "NIMA hose, extrusion molding", and left.

Can NIMA rubber only be used to make tires?

Soft, light and flexible NIMA "hose", isn''t it much better than metal hose?

What a bunch of idiots!

As for "extrusion molding", it''s just a matter of thinking. When the melted NIMA gum is squeezed out of the barrel with a specific shape, isn''t there a hose?

This processing method is very fast, the shape of the hose is also very stable, almost no deviation, and want to squeeze as long as you squeeze, 200 meters long does not matter, dish up also does not take up too much space.

It''s not like a hard metal tube. It''s too long to hold.

There are many smart people in Rune Research Institute. Although the Lord only gave a few key words, they bumped out a set of NIMA extrusion equipment with high processing efficiency.

First, melt the rubber with the "thermal magic heater", and then use the mechanical mechanism similar to the plunger pump to squeeze the rubber out. A heat recovery device is installed at the extrusion port, which not only saves fuel greatly, but also speeds up the cooling of the rubber tube.

There is another advantage of extruder, as long as the change of different sizes of barrel, you can get different diameters, different shapes of hose, which also greatly expand the use of hose.

When using NIMA hose to transport oil, one end of the hose is inserted into the heavy oil depot, and the other end is connected to the high-pressure oil pump. It can transport 2 or 3 tons of heavy oil in one minute. The replenishment efficiency is much higher than that of manual transportation, and the sailors don''t have to be tired like dogs.

Nima hose has a very good property, it is almost insoluble in any solvent, acid and alkali resistance is also good, which is significantly better than the rubber on earth.

As we all know, rubber pipe can not be used to deliver fuel, because it will dissolve in the fuel.

Because rubber is a macromolecule, after adding solvents such as gasoline or kerosene, the small molecules of solvent will penetrate into the rubber macromolecules and make them expand. After expansion to a certain extent, the macromolecules will completely disperse, which is called dissolution.

Nima gum is different. Its main raw material, alginate, has a small molecule. After NIMA powder is added, the two sides are combined very closely and are not easy to be destroyed by small molecules of solvent.

The only drawback is that the molecule of alginate is not a kind of compound that can exist stably for a long time, and it will appear aging after reaching a certain age.

After the completion of replenishment, Odin and Haichao directly adjusted the large gearbox of thermal magic engine to third gear and drove to the next target at a speed of more than 22 knots.

Although the speed of the third gear is the fastest, the fuel consumption is relatively high, which is about 8% higher than that of the second gear.

The fleet will maintain this speed for the rest of the time until it reaches the glow continent.

In the cold winter months, there are too many storms on the ocean. Almost half of the time, the sea surface is in a state of strong wind and waves. Even the trimaran, which is more resistant to wind and waves, dare not go to sea.

Only the "window period" between the two storms is suitable for sailing. In order to seize the time, the fleet must speed up, regardless of saving fuel.
