There are many waterways to get to the Izu Islands from Maruyama Castle in Izu Province, and the nearest waterway is the one to Wanoshima. Both Fuyong Yamasui and Nine Ghost Jialong are very clear about this point, and Nine Ghost Shotaka has arranged all his ships except for large and small ships in a place three kilometers northwest of the big island, which will be the location where he and Tominaga Yamasui will have a decisive battle.

Tominaga and his men drove towards the Izu Islands with great momentum, and their fleet had never had an opponent in the area around the Izu Islands, so their morale was very high this time.

Although the Nine Ghost Jialong has absorbed some, the small wealthy family and the samurai of the national family who have hatred for the Hojo family have definitely increased their strength.

But because of the entire change in history, there are no ironclad ships that dominated the sea on the side of the Nine Ghosts, nor are there as sharp ships and artillery as the Kuroda family's naval army, as well as many long-range firearms.

This is an old-style water duel, and it is not easy to determine which side will win in the end, which needs to rely on their mastery of the wind direction, their familiarity with the hydrology, the control of the ships, the use of formations, the understanding of their own personnel, and the temporary battlefield scheduling, etc. It's really hard to say who will win in the end.

The weather on the day of the decisive battle was very good, there was not even a trace of clouds in the sky, in such an early summer, such a sunny and mild weather was already very good, and the absence of rain was definitely conducive to the naval battle.

For summer, the monsoon is a topic that cannot be avoided in the whole of East Asia, and it is clear that there is no wind at all today, as if God is blessing them to have a smooth battle.

The ships under the Nine Ghosts Jialong have already lined up on the water, and this is the butterfly array that the Nine Ghosts Jialong likes to use. The so-called butterfly array is about the transformation of the crane wing array on the water, with the sides open and the general's ship in the middle. Therefore, the entire army formation formed a butterfly stretch, and such a formation was conducive to attacking the enemy in the middle on both sides.

On the opposite side, Fuyongshan is best at using a cone-shaped assault formation, which is a kind of triangular formation with a thick middle and relatively weak on both sides, which is conducive to impacting the opponent's center, which is the most important place, that is, to instantly defeat the opponent's center, and kill the opponent's main general, and at the same time play a role in disintegrating the opponent's entire military formation.

One is to attack the enemy in the middle, and the other is to encircle the enemy, the choice of these two systems is the familiar trick of the two sides in their respective water battles.

It's just that Tominaga Shan saw the enemy on the opposite side, and when he just ordered to prepare the formation, he didn't expect that the Nine Ghost Jialong army on the opposite side had already moved, and saw that more than 160 ships on the other side, under the order of the Nine Ghost Jialong, all drove in the direction of the Izu National Naval Army, without any stop, and at this time, the Izu National Naval Army, the conical attack formation has not been completely opened.

However, the formation of the Izu National Navy already has some shapes, and the middle is thick, and the two sides have not yet been formed, so it seems a little hasty, but in the face of the opponent's attack, as the attacking side, and there is not much preparation, Tominaga Yamasui can only order the whole army to start attacking.

Why did Nine Ghost Jialong use the Butterfly Array in this place, because there were more than a dozen Ataku ships in his array, and these Ataku ships were all collected and built by him over the years.

He was originally located in the territory of Shima Country, which was a production area of fine timber used for shipbuilding within the island country, which was very suitable for building large and small ships, so after the construction of the ships of the Nine Ghost Naval Army, they were more solid than the ships of the Naval Army in other places, which was the advantage of his ships.

Moreover, the Nine Ghosts Jialong has installed ramming angles in front of all his ships, which is a special attack method that is conducive to directly colliding with the enemy with the hull, and this attack method is also common, but it will appear more in front of the ships in the west.

On this side, the main attack method of Fuyongshan is to disrupt the rhythm of the opponent's entire formation through the continuous interspersing of small ships, and then kill and injure the opponent's personnel and burn the opponent's ships through continuous rocket attacks.

But this time, Fu Yong Shan Sui really made a mistake, because the Nine Ghosts Jialong had long been used to it, and this kind of attack trick that the island nation naval army was very accustomed to.

It's not like they've fought with other naval armies before, and an attack like this doesn't have much effect on them, at least they already have a way to deal with it.

So when the small ships on this side of Fuyongshan rushed into the formation of the Nine Ghosts Jialong, there was no panic on the side of the Nine Ghosts Jialong, and all the Ataku ships quickly appeared from the formation and rushed towards those small boats, and the role of the Ataku ships was very simple, that is, to crash these small boats.

"What's the situation, what are the Kuroda family's sailors going to do?" When he first saw this scene, Tominaga was a little stunned with himself, and then he knew exactly what the Kuroda family's water army wanted to do.

"Oh no, we're fooled." Tominaga shouted loudly.

"What should I do, my lord?" A ship admiral asked him.

"We can just get everyone to gather in the middle first, and then we will attack, if we haven't collapsed yet." Obviously, when he said this, Fu Yongshan was already a little deflated with this master of the navy.

And soon all the situations were developing towards the worst he could imagine, the advantage of the Ataka ships on the side of the Nine Demons was too great, and the small boats on the side of the Izu Naval Army had already been sunk in the impact.

When the other ships saw this situation, as soon as they encountered the Nine Ghosts' Ataku ship rushing up, they would immediately dodge around, and it was because of this evasion that not only did they not cause the destruction of the enemy's butterfly formation, but it was their own, and now it was chaotic.

And at this time, the butterfly array of the Nine Ghost Family, the thickest wings on both sides began to wave, and the wings completely stretched out to the surroundings, from the butterfly array to the crane wing array in an instant, and from both sides, the water army that followed the Fuyong Mountain pressed the past.

At this time, the Izu Navy was still in the chaos just now, and it was not able to recover, and this time it was obviously occupied by the Nine Ghost Family, and soon formed an encirclement of the Izu Navy Army, making them even more chaotic.
