The pirates sat and forgot, and they really believed the nine truths and one lie.

In order to enable ordinary naval soldiers to exert their combat effectiveness, naval ships entered the era of giant cannons and large ships. In this pirate world where there are not even wooden airplanes, super battleships are the answer.

After all, those who can possess the ability of the Flying Fruit are rare, with only one or two in each force. Such a small number does not pose a threat to battleships.

Due to the shortage of energy in this pirate world, there is no cheap energy such as oil and coal. However, by chance, the scientific forces discovered the substance called methane hydrate in the deep sea.

Methane hydrate has the characteristics of high calorific value, low pollution and large reserves. It is mostly white or light gray crystals, similar in appearance to ice and snow, and is used as a new type of high-efficiency energy.

The navy's new warships are all powered by combustible ice. These deep-sea substances are enough to drive 10,000-ton steel monsters, making the navy's battleships quite superior in speed.

Most of the pirate ships floating on the sea are powered by sails. The battleships are simply a dimensionality reduction attack on those wooden ships, and they can directly smash them with the metal steel plates on the surface.

During the landing operations, the artillery support provided by the naval strategic ships made the defending side miserable. All are equal in front of heavy artillery.

The battleships played a very important role in making it easy to attack the Revolutionary Army headquarters. The Revolutionary Army was bombarded so hard that they could not raise their heads, and the entire White Earth Island was reduced to a scorched earth.

Although each battleship is worth a lot of money, compared to the Peacemaker, which is difficult to mass-produce, the new type of ship is more cost-effective and much easier to maintain than high-tech equipment.

Battleships have formed a unified industrial process, and each ship is roughly a one-to-one replica, which has greatly accelerated the speed of shipbuilding. The Navy Headquarters has been in a state of ship explosion, with at least twelve new battleships launched every year.

The garrison navies around the world were very lucky to be allocated one. This time, Admiral Akin brought out two new battleships at once, plus some old naval warships. Those old antiques could only watch from behind and witness with their own eyes how the darlings of the navy of the new era perform.

Several of the fastest-running strange species have already gone into the sea, followed by a huge army of giants. The intention of these insane giants is very clear, they want to actively attack naval ships, and they can no longer delay at this point.

"I didn't expect that Doflamingo's giant weapons have developed to this point. Fortunately, the navy's technological level has not stagnated in recent years. Prepare to use up all the ammunition," Admiral Smoker issued combat orders to the two battleships through the Den Den Mushi.

Each shell used by the battleship's cannon weighs at least a thousand pounds, which is simply beyond the reach of human power to move. However, automation has solved this problem. Shells can be easily taken out of the ammunition depot and loaded automatically, making the firing rate as fast as possible.

"Fire at Dressrosa!"

"fire"!

The two admirals gave the order to fire at the same time. Nearly thirty huge cannons of the two naval battleships were fired at the same time in an instant. Every shot left a billowing black smoke in the air, allowing the giants to experience what a high-yield artillery shell is and feel what a saturation attack is.

The fierce artillery fire from the two battleships poured down straight ahead. Although these giants without any sense of pain had different heights, they were all equal in the face of the artillery shells.

boom! boom! boom! boom!

This weapon was created for war. Every shell would leave a big hole on the ground. The giants nearby would either be blown to pieces on the spot or turned into torches. All carbon-based creatures are afraid of being burned by fire.

The twenty-meter-tall strange giant either had his legs blown off or his entire upper body was blown away. The moment he hit the ground, he had no chance to recover and face the next round of artillery attacks.

The port was bombed into a black world in a short period of time, with thick smoke mixed with sporadic fire sources. The once prosperous port of Dressrosa became a scorched earth, and thousands of giants returned to the earth under high-density bombardment.

There were only a few dozen giants who managed to survive, with their heads intact. They lay on the ground and used steam to recover their bodies. However, they no longer posed a threat to the navy, and these remnants could be dealt with by subsequent landing troops.

Admiral Smoker took the telescope from a naval soldier and observed the situation in the port through the lens. The results of this battle were very significant, and most of the enemies were eliminated under the artillery fire.

In the past, when faced with such troubles, the admirals would have to enter the field and use large-scale AOE to deal with the miscellaneous soldiers. But with the new battleships, it is different. If the enemy cannot even withstand the artillery shells, then these weaklings are not worthy of the admirals' attack.

"Ajin, let me show you this battleship. It's really a magical weapon for attacking islands. If our navy is equipped with this kind of ship on a large scale, there will be no island in the world that we cannot attack."

General Blue Snake took the telescope and observed the battlefield situation, and added: "The power is great enough, but unfortunately it still has the old problem, the accuracy of the artillery fire is problematic."

The battleship's cannons can fire several kilometers away, but their accuracy is rather worrying. If they attack distant targets at sea, there is a high probability that the missiles will miss and fall into the sea.

This time, artillery fire was used to clean the port, and some shells landed in the residential area behind, which may have caused casualties. However, these are necessary sacrifices, and the navy has minimized civilian casualties.

The four Celestial Dragons were not locked up in the cabin by the navy. Instead, they took the initiative to invite them to board the battleship to let these old-fashioned people see the strategic weapons of the new navy.

After only twenty minutes, the largest port in Dressrosa was completely torn apart by artillery fire, which made the Celestial Dragons feel unreal. They knew that the Navy had the Demon Slayer Order.

But to completely destroy a large island, the naval ships of five years ago were just showing off. The old ships had seriously insufficient firepower, and only battleships could completely destroy the targets on the island.

"If these shells fall on the holy land of Marijoa, it will probably take less than half a day to destroy it," said Saint Charlos, a mentally ill guy who actually thought of the navy using battleships to bombard the holy land of the Celestial Dragons, causing the other three Celestial Dragons to roll their eyes.

"Is this the power of technology? It can allow some ordinary people to have such powerful destructive power." Saint Musgarud was thinking about a question. He really didn't know where the navy's growing ambitions would go.

Ordinary animal-type devil fruit users, plus the more fleshy ancient species, can hold out for a few minutes under this kind of artillery fire. The navy is just consuming its own shells, which can be produced infinitely as long as the raw materials are sufficient. If a devil fruit user dies, there will be one less.

There are only so many devil fruits in the sea, and it takes a long time to train an elite one. But if the navy can solve the problem with just a few shells, the pirate forces will suffer a huge loss.

Don Quixote Musgarud Saint's sister was invited by the navy to become a navy admiral. In this great change that has not happened in 800 years, this may be a rare way out.
