~ Astra ~

There is an enemy fleet in front of you.

Two large ships, six medium-sized ships, most small ships.

The eastern and western marquises have not moved the Great River fleet, but they are over there because the baron, who is captain of a large ship, took Toa's side by means of a letter.

This is only two medium-sized ships on one of my larger ships, and the rest are small ships and ships used for supply and transport.

But this ship and the small ship based on the blueprints that she left behind. And a battle you can win at your leisure if you have the firebox created by Lord Jumka.

Don't be alarmed. But I'm only confident I can win.

"What's happening to those on the other shore?

"Yes, we have received a fire box from Lord Jumka and placed it on a small rotating shaft ship."

"Really, all right, general. The battle will begin soon. Inform the metal wizards at the bottom of the ship of Mikasa's readiness for battle."

"Ha."

The ship that kid thought about. I repeatedly experimented and failed, and it took me over a decade to make it happen.

But that kid thought of a screwed super large ship. By rotating the propeller called Screw at high speeds with three metal wizards or seven people who can use magic, it gains propulsion. A ship that does not use the power of wind or swing.

We do not have to employ large numbers of hand slaves, food is suppressed, and there is less fear of the plague endemic to them.

Conventional large ships were limited by the endurance of ammunition, personnel and ships, with large crossbow guns on the front and two on the sides.

However, in this ship, which is more than two turns larger than a conventional large ship, you can load the roundabout, which is a crossbow gun bullet, in a gap without hand slavery, and you can carry many people and feet on it. As a result, seven large crossbow guns can be placed on each of the super large crossbow guns on the front.

That's exactly the fortress on the Great River.

And it's not just big. Whereas the speed is also faster than that of a normal large or medium-sized ship, it is also faster than that of a small ship because the water wizard is manipulating the water flow. Well, small circles don't work.

Oh, it looks like they're ready over there. Shall I start?

~ Jumka ~

Watching the boat fight while building a fire box from the top of the hill.

Astra asked Kyle to take care of this Grand River Battle to make up for the delay in entering the war, and Kyle agreed.

I mean, don't ask me to help you by saying you'll do it yourself. Well, if that means you want three fireboxes, fine.

The fire box was completed and placed on three small ships.

There are five to twenty other small ships on board, but only those three have no other combatants.

Small ships vary in shape.

As far as I can tell, some moulds are rowing with oars and moulds where those who can use the magic of the wind can make wind and move with sails and those who can use the magic of water can magically make water flow and move on.

"It's time to start. It could be dangerous here, so I can see the boat battle. Come here."

And Astra's men told me to go up to the high ground and watch the fight.

An enemy fleet arrives from the other side, starting with a small ship coming forward and shooting each other with bows and arrows.

Consider the wind and water flow at the steer's arm display. And I guess I have to move so I don't get surrounded.

"Is that the decision not to target the steerer?

"Yes, no one does such a cowardly thing. Well, I can't help but hit a stray bullet."

That's the same thing as in the last life.

As the shooting of small ships begins, now medium-sized ships begin to reach the battlefield in front.

This is a medium-sized ship and a large ship carrying Astra came at the same time, but because the wind is the only way to proceed, we have not yet reached the battlefield.

A large ship under Astra's command roared and increased its speed.

That's causing a big wave in the Great River and a small ship is overthrowing.

"Are you okay with that?

"It's okay. The only enemies there are. Mikasa...... That's the name of that ship, though. That ship is making a signal and we're starting the retreat."

Mikasa...... Mikasa? Could...

"Was it Noel from the Patriarchate who designed that ship?

"You understand very well. It's a supermassive battleship created by Astra over more than a decade, based on materials invented by Noel."

I knew it. Did he keep a record about the ship?

Mikasa leaves the boat around her and proceeds, releasing the crossbow gun in the front, passing straight through the side of the medium-sized boat. Even then, a crossbow gun roared and pierced the hull of a medium-sized ship, and Marutai, a bullet, is magically bursting.

That's a roll. They also shoot arrows and oil canisters, but they have barely arrived out of range. When the attacked medium-sized ship is crossed with a crossbow gun, it becomes unnavigable and stops.

"Look, there's a small ship coming after Mikasa and it's attacking."

An arrow from a medium-sized ship that stopped a small ship that came with Mikasa, as well as throwing an oil kettle as it scratched its magic attack. An oil kettle is thrown into the gap with the destroyed hand and the magic of fire is thrown.

I heard the ship's surface was coated against magic, but they didn't do that inside.

One medium-sized sailor after another jumped into the Great River as the firehand rose to the medium-sized ship and burned as it was.

As enemy ships retrieve sailors who have fallen into the Great River, the small ships on their side will shut up.

"Is that a decision you shouldn't attack, too?"

"That's right. Isn't it cowardly to attack where you're helping your fallen companions?"

Are the rules also different in land and water wars? We don't chase retreaters, either.

It is a battle between medium-sized ships while one of them is on fire over there.

I thought this one was slightly unfavourable due to the difference in numbers, but Astra's large ship is circling like an alpha and shooting crossbow guns in the front and side of the ship around.

The medium-sized ship also tries to deflect, but is flirting with the speed of Astra's ship.

When three more medium-sized ships become unnavigable, roasted small ships flock to one, and enemy small ships are gathering to prevent them.

The other two ships each medium-sized ship stranded to the side.

"That one went to the enemy ship to slaughter him."

Astra's subordinates' supplementary explanations come in. I still appreciate that.

The other medium-sized ship is struggling with Astra's big ship opponent, so he can't get into the rescue ship being slashed.

A call came from one of the medium-sized ships over there.

"Apparently, you either captured the enemy captain or debated him. They think it's just a matter of time over there."

I guess that one also succeeded in slaughtering because the other ship cheered me along the way that explains it.

An allied medium-sized ship moved out again. It would be to help Astra's big ship.

But a big ship has arrived on the battlefield. It will be a battle between big ships from here on out.

That's what I thought. But when Astra's big ship turned around and turned against the enemy's big ship, the four ships behind him left and turned to the side at a fierce speed.

It's faster than any other small ship.

When I stared, Astra's men gave me my binoculars.

The steer's alone, and nobody's on the rest?

No, there's my fire box on it.

I guess the water is sprayed from the barrel behind the ship in momentum to use it as a power source.

The enemy's defenses have also been scratched and three of the four ships have been stabbed by a large enemy ship. I retrieved the cartridge spraying the water behind me and rode into one of the remaining vessels and left.

"There was a signal. Master Jumka, please activate the fire box."

"Okay."

I signaled the wizard of the dirt I was lying next to and broke three boxes, activating the magic to collect the oxygen around me.

Three columns of fire rose from the small ship that stabbed the bottom of the large ship and instantly encircled the large ship with fire.

I can also see it burning on a small boat that was unlucky due to the wind.

Don't let's see it because it's cruel any more.

The other large ship that saw the large ship crack and sink from the burning and collapse center flew a white flag and the medium-sized ship flew a white flag along with it.

This is how the battle ended and I spent the day processing it after the war. We were to cross the Great River.

Many young men and horses were afraid of their first boat, but it took us two days to cross the river.

In addition to Astra's army, we headed straight for the King's Capital.
