The first convoy of the marine city of Amar stopped sailing tomorrow for the bandit flotilla Kaitan (Kaido) crusade, and I was preparing to track the flotilla as well.

A stealthy submarine U-boat VII was chosen from a large number of ships available for VMB. I'm going to steer this and start with knowing the naval battles in this world.

He was visiting the Marida Chamber of Commerce in Amar to check the operability and habitability of the U-boat and secure food during operations that he thought would take several weeks.

"Guest, all you need is food, is the water okay?

"Yeah, I don't mind magic tricks when it comes to water."

I actually have a water storage tank on my U-boat, which would be in exchange for a fuel gauge, but I'm going to use that. Basically, vehicles and ships appearing on VMBs are diverged from real weapons in order to balance the game.

Sea navigation speeds and sea navigation speeds can also travel faster at sea, but their speeds are uniform depending on the category of vessel, or the performance of torpedoes and uniform firing rules.

Of course, ships named High Speed have an increased maximum speed limit, or many ships with high-powered warheads such as dedicated torpedoes are available.

Together with the director of Borroy at the Marida Chamber of Commerce and Shipyard, he will also purchase household goods other than food. I have the Marida Chamber of Commerce for all the charges, I said no once that you didn't have to do that, but it seems to be strict from Marta, the chairman of the Chamber of Commerce, and he'll have trouble finding out that he made me pay.

Mr Malta, the Kingdom of Kurtomerga only partitions one of the leading chambers of commerce, and where it is tightened, it seems to be tight.

After I finished shopping, I was listening to the story about the sea area I was aiming for while eating with them as I had promised.

They also show you valuable nautical charts, and when you're aware of taking screenshots, a capture sound that resembles a camera shutter sound sounds in your brain.

Just as the mode changes in vision and UI information were now visible without goggles, it seemed that the screen capture could also be saved simply by being aware of it.

"But customers. Are you sure you want to go out to sea alone? Even though the sea is relatively calm this time of year, it is a time when there will be more storms. I don't know what your ship looks like, but please sail with great care."

"Thank you. We have a convoy of escorts nearby on the road, so we'll get help from you when it's dangerous."

Pack your minimum knowledge with advice on life at sea afterwards. We set off offshore during the night.

The next morning, I exposed only the command tower part of the U-boat to the sea, and I was waiting for the first convoy to leave the port. Already ready ready ready for tracking, I was waiting for the black supply BOX to open at my feet.

Shaken by the waves for a while, I saw a shadow on the horizon that seemed to be a convoy of escorts. The number is seven... I don't know if it's more or less, but I feel the shape is similar to that of a carrack ship, which is not the same shape as a merchant ship.

Six inner ships are about half the size of a U-boat with three masts, would be less than thirty meters long, only one has four mast ships nearly that size. Maybe that's the flagship.

Get your hands on the replenishment BOX at your feet while you're still at your distance and take out another important item you need for this pirate fleet crusade.

Removed from the supply BOX was a small grey drone, the RQ-11 Raven. This small reconnaissance aircraft operates primarily in the United States military and its allies and has a thin torso about a metre long with wings one metre long and a small electric propeller.

There is a camera on the small cockpit part, and the footage shown by Raven is shown on the window monitor of the TSS (Tactical Support System), which allows you to control the Raven with a window monitor just like a vehicle or a U-boat.

Press the Raven start switch and the electric propeller will make a good sound inside and rotate. It is possible to be noticed if it is too close to the fleet, but Raven can rise from an altitude of about 300 to 400 meters.

From the command tower of the U-boat toward the convoy of escorts, fly the ravens to throw. Check the ravens going up high in the sky, and immediately use the window monitors to get the ravens over the convoy.

There's still a distance, but I'll do what I have to do now. Several reconnaissance aircraft are available for VMB, but any reconnaissance aircraft can target a target by touching the target shown on the window monitor.

The locked goal has a square frame, and that frame is reflected not only in the window monitor, but also in my vision as AR (Augmented Reality).

Furthermore, the AR frame color can be changed, locking the seven ships of the convoy to be tracked and keeping them in yellow colouring.

Now we're ready. To be clear, I don't know the route to the intended waters. So I was going to target the convoy and track it down.

If you lose your fleet, you could have isolated yourself on the high seas. But now you won't have to worry about that either.

Raven, who keeps showing the convoy, comes back under me automatically with one return button. When the Raven breaks, the lock disappears, so I want you to return to me and stay in the inventory.

I also went down to the inside of the U-boat, changed the target of the operation to a U-boat, followed the convoy of escorts and started the voyage.

◆◆◇◆◆◇◆◆

A week has passed since we sailed the marine city of Amar. I've flown periscopes and ravens while sailing and observed convoys of escorts, but the convoy's speed was faster than I'd imagined.

The factor is not magic, but superior shipbuilding technology. I thought it was wind dependent speed because it is a sailboat, but from time to time a powerful trail floats at the stern, temporarily increasing the speed and returning to wind dependent speed and natural trajectories.

Repeating that, the fleet continued its voyage. I don't know if I can actually dive into the ocean to be sure, but apparently the ships in this world thought that there was a ship with a screw at the stern, spinning it with magic or demonic stones and increasing its speed.

The increased speed also seemed to speed up the arrival in the intended waters, but the fleet had no spare time for training, as it frequently carried out the reconfiguration of formations that seemed to be combat training, or was inputting long-range magic into the sea that seemed to be a cannon replacement.

Conversely, I was thinking about what I had been doing the past week, in addition to observing the convoy of escorts, how I would intervene in the battle I was going to anticipate, what I would use, and how far I would end up doing it, and I was dawning in preparation and practice for it.

Then we finally arrived in the waters where the uninhabited island at the relay point is located.

The convoy of escorts docks a short distance from the uninhabited island and sees the sailors heading towards the uninhabited island by lowering the small boat.

According to Mr. Borroy's story at the merchant ship yard, the island is a fairly large uninhabited island, with fruit tree swarm areas and flowing waterfalls of fresh streams, where water and food can be added, as well as simple stone lodging where we don't know who built it, which can be used as a temporary campsite.

The convoy also intends to use this deserted island as a front-line base to determine the home of the pirate fleet from among the surrounding islands and to pursue a complete crusade.

I couldn't stop being excited about the naval battle that was finally coming as I watched one small boat after another going to an uninhabited island via a window monitor from a periscope.
