"Woooooo The horns sounded on the sea, and the gunboats of the two sides were already less than two kilometers apart, and gradually reached the effective firing range, and the artillery fire on the sea roared, and the two sides began the first round of test-firing strikes.

On the side of the Portuguese fleet, at the forefront were the two gunboats "Dreadnought" and "Holy Flame", and the gunners on board were constantly adjusting the positions of the battleships and the angle of the guns according to the positions of the two sides and the effect of the test firing. Around the two gunboats, there were fifteen small frigates to protect the safety of the main ship.

Several gunboats of the General's Mansion have also entered the battle area, and the roar of artillery fire is constantly heard on the sea, and the two sides have begun to exchange fierce fire.

When Portugal first established colonies around the world, it was necessary to carry large quantities of goods and soldiers across the Atlantic, and the main warships at that time were the Naya and Karak, which were no longer up to the task.

Gradually, Portuguese military experts invented the "Galen" warship, which combined the advantages of these two types of ships and became famous for a long time. It generally has 4 masts, with two front masts hanging railing sails and two rear masts hanging spinnakers. The standard length is 46 meters to 55 meters, the displacement is 300-1000 tons, there are five floors of the long deck, and the aft building is very high.

This newly designed new generation of "Galen" warship is relatively long, fast, maneuverable, and maneuverable much more than the old warship Karak.

Of the sixteen gunboats in Portugal, 10 were the latest "Galen" warships, and the warships of the Great General's Mansion and the Takeo of Guizang were all Karak warships that were a generation behind.

As soon as the two sides came into contact, the Portuguese Sacred Flame's new "Galen" warship, because of its strong maneuverability, obviously had an advantage, and in a moment, it had already lightly damaged a gunboat in the General's Palace.

Three hundred meters from the "Holy Flame", eleven heads surfaced from the sea, watching from afar.

Dugu Xiaotian looked at the gunboat for a moment, made a gesture, and a Jinyi guard master took out six small cannonballs from the basket on his waist, tied them with ropes, and handed them to Dugu Xiaotian.

"Action! Jack Drop! Dugu Xiaotian let out a low shout, and eleven people carried the Thousand Jin Fall Exercise and sank to the bottom of the sea.

When diving in the ocean, the main problem to be solved is breathing. As the depth of the dive increases, the pressure increases, and the nitrogen in the air will penetrate into the cells of the central nervous system of the human body, causing "nitrogen anesthesia".

Therefore, for longer or deeper dives, it is necessary to have special equipment, which can ensure that the diver breathes.

In addition, diving is not only a matter of breathing, but another threat that humans face when diving is decompression sickness. Because for every 10 meters of increasing the depth of the sea, one standard atmosphere is added. As the pressure increases, the body's blood's ability to dissolve air increases. If the diver returns to the surface from deep water too quickly to decompress, the gas dissolved in the blood and body tissues will form bubbles, blocking blood flow and can be fatal in severe cases.

Ordinary people can only dive 10 meters, after training, they can reach 20 meters, and professionally trained personnel can dive to more than 100 meters.

Dugu Xiaotian made a simple tool for storing oxygen from cowhide sacs, and sixteen cannonballs were hung in the rattan baskets on each person's body, adding dozens of kilograms of weight to facilitate everyone to sink underwater and move.

After training, the masters of Jinyi Wei can dive into the water for about 30 zhang (100 meters), and the limit diving depth of Dugu Xiaotian far exceeds them, and can reach 50 zhang. The master of the water ninja who returned to Takeo in Tibet, although the water escape technique is strong, because there is no special breathing equipment, he can only dive to a depth of about 20 zhang in the sea.

Dugu Xiaotian and the others sneaked under the water at a depth of thirty zhang for a while, and came to the bottom of the "Holy Flame". Dugu Xiaotian made two gestures underwater, and the other ten people stood still, Dugu Xiaotian's figure rose more than 20 zhang, and came to a position five or six zhang away from the bottom of the gunboat Sacred Fire.

Dugu Xiaotian grabbed two cannonballs, and ran the method of releasing real energy, between the flashes of purple light, Hongmeng's true energy was all over the surface of the cannonballs, he shook it hard, and the two purple cannonballs slid quickly along the current, and between the two breaths, they collided with each other at the bottom of the "Holy Flame".

With a loud "boom", the hull of the Holy Flame shook violently, the hull of the ship tilted, and the six shells that had just been fired lost their crosshairs and bombarded the sea surface fifty zhang next to the Shenmu of the General's Mansion, causing a splash.

Robinson, the captain of the Holy Flame, was taken aback and immediately ordered the second mate, Rohr, "Rohr, someone is attacking our gunboat underwater, quickly send someone to inspect the bottom of the ship and close the lowest deck." In addition, order the frigate to attack the enemy who is raiding under the battleship. ”

As soon as the words fell, there was another earth-shattering bang, and the Flame shook violently, and the ship tilted. Robinson and Rohr fell to the ground, looking embarrassed, and they scrambled to their feet.

"Frigate, shoot to the bottom! Send divers into the sea to kill the raiders. Robinson yelled.

More than 300 musketeers raised their guns and fired indiscriminately at the bottom of the Holy Flame, and then more than 100 divers, armed with sharp blades, jumped into the sea.

The situation of the bullet in the water is not the same as in the air, the density of the water is 1000kg/m, and the density of the air is 1.29kg/m, the difference between the two is nearly 800 times, the bullet in the water is extremely resistant, the power is less than a zhang, and it cannot hurt Dugu Xiaotian underwater.

Dugu Xiaotian threw three rounds of "Hongmeng Zhenjin Cannonballs" at the bottom of the ship, and it was expected that the two decks of the Holy Fire gunboat had been blown through, so he dived to 30 zhang and swam more than 100 meters to meet his subordinates.

More than 100 Portuguese divers searched back and forth about three feet underwater, and found no figure, which was amazing.

After a tea hour, the Flame could not move because of too much water in the cabin, and the gunboat began to sink faintly, and the more than 1,000 Portuguese sailors and soldiers on board had to flee to the small warships around.

"Boom", two shells bombarded the deck of the Holy Flame, sawdust flew over, and the Holy Flame was even more damaged. Now that the naval battle was in full swing, the Flame could not move, and became a live target, and was sunk by the warships of the General's Mansion in a matter of moments.

On the General, everyone used a clairvoyant mirror to see that the Holy Flame had been sunk, and they cheered. Yanagi Senbei said excitedly: "The raid has taken effect, and we are going to win this battle." ”

Yanagi Yukiko's face was flushed with excitement, she smiled slightly, and said to herself: "Xianggong is so strong!" ”

The Holy Flame was sunk, and there was an uproar on the Thousand Blades and the Holy Sword, and the leaders of the ships were talking. Guizang Takeo's face was bruised and his face was hideous.

"Mizukeiko, lead the entire Mizuninja Department to dispatch and go underwater to repel the attacking enemy!" He slapped the side of the ship angrily and shouted angrily.

"Yes!" Shui Huizi has long been relying on water and is ready to fight. Without hesitation, he beckoned thirty Mizube ninjas and went to the sea.

The warship groups of the two sides met, and the battle on the sea within a radius of more than 10 kilometers became scorching, and gunboats and warships were constantly destroyed. Originally, the Portuguese warships could have the upper hand because of their superior maneuverability, but I don't know what secret weapons the General's Mansion used underwater, and they actually sank two new warships, the Holy Fire and the Holy Soldier, in succession, and the General's Mansion actually had the upper hand in the early stage of the naval war.

Shui Huizi led thirty masters of the Water Ninja Department to launch a carpet search on the sea, and it was almost two quarters of an hour, but there was no trace of the enemy, and he couldn't help but be furious.

"Boom!" The third Portuguese battleship, the Holy Water, was blown up at the bottom and began to sink slowly.

"Ring around that direction!" Mizukeiko ordered, and a group of ninjas approached the Holy Water and searched carefully. "Chief, there is no trace of the enemy!" After a long time, several team leaders returned to Shui Huizi one after another. Shui Huizi gritted his teeth, "The enemy must be deeper under the sea, sending masters to dive down to find their traces." ”

With the escalation of the war, many Portuguese and Dongying sailors had to abandon their ships and float on the sea because of the destruction of their warships. If they are lucky, they will be rescued if they encounter a friendly ship. However, many of them died, and the musketeers on both ships would mercilessly shoot the enemy when they saw the enemy next to the ship.

On the Portuguese marshal ship Holy Sword, Captain Hahn had a serious face, commanding the flag bearer, and constantly giving various instructions to other warships. Under the protection of the Zhao sisters, Badelle watched the battle happily on the side, and Yu Feihua took the twin demons of heaven and earth to guard the side.

First mate Andrei panted, "Captain, we have already lost four new gunboats, will this battle continue?" ”

Hahn's eyes were like falcons, looking at the fleet of the Great General's Mansion, and he was silent for a long time, "In this war, there is the devil of the sea on the Dongying side, and we can't take advantage." ”
