At this time, the Arabs appeared on the island of Java, initially as merchants, but they were also keen on politics and could bring advanced science and technology, and slowly began to influence the policies of the Mahabacher dynasty. If the original history is followed, this East Java state will expand and eventually unify the islands of Java, Sumatra, Kalimantan, and the southern part of the Malay Peninsula, which is larger than the area of Indonesia in later generations, and completely become an Islamic state.

At this time, the sphere of influence of East Java was mainly on the island of Java, and there were settlements on some islands such as southern Sumatra, southern Kalimantan, southern Sulawesi, and Bali, but they were not too big, at most they were tribes, villages, and the like, and they were not worth fighting. Hong Tao's main targets were the port cities or villages on Jawa Island. For example, Surabaya (Surabaya), Sunda Galabas (Jakarta), Pasaima (a port on the southern tip of Sumatra Island, next to the Sunda Strait), and New Corisa (a city south of Surabaya).

The approximate location of these port cities, Hong Tao has already asked from the mouths of the Southern Song Dynasty maritime merchants and the Pu family, and the specific location has to be found later. The rest of the cities located in the interior Hong Tao plan to go to the place to think about it, and if you can sneak attack, you will send marines to steal it, and if you can't sneak attack, it doesn't matter, keep them, anyway, every year the fleet of Jinhewan will come here to take a turn, as long as there are ships, ports, whether it is fishing boats or merchant ships, they will all be killed. For the time being, Hong Tao can't control how this Jawa country develops on Jawa Island, but they can't go to the sea, even if they are willing to abide by their own rules. Hong Tao doesn't intend to let the country continue to exist. Again, that's the same sentence. No one is idle. Let's toss together, idlers are easy to get into trouble, and they will be honest when they are beaten all day long.

The first stop from Brunei Port is not Java Island, but Bangka Island, which is located east of Sumatra. It is said that there was a Javanese port and camp here, which was also their northernmost stronghold, and Hong Tao planned to pull it out first, and then carry the eastern side of Sumatra to the south. Go all the way to the Sunda Strait, and then attack the port of Pasaima. By attacking these two Javanese outlying ports, you can test their true strength, as well as the approximate attack power of your own fleet. If there is no problem, then cross the Sunda Strait and start a ten-day tour of Java Island, and if there is a problem, turn around and return to the sea to complete part of the strategic goal.

Four days later, when Hong Tao's fleet reached the west side of Bangka Island, the Javanese camp was empty, and not a single boat or person could be seen. A few of Langya's marines went up and searched for it. Judging that there has been no one living here for two or three months, it seems that it has been evacuated a long time ago. As for why it was withdrawn. It is estimated that it is related to the tragedy in the port of Malacca, and until now, the bodies of the Wu family, father and son, and the Pu family are still hanging on the fortress of the port, and they can be seen as long as the ships are docked. The Javanese probably knew that the attack had failed, so they abandoned the most reprisal-prone stronghold and retreated elsewhere.

"Oh, that's fast! Go, go to the port of Pasaima, I don't believe they can all leave! Hong Tao was very disappointed, he was trying to see the power of these cannons, and he held it for several days, but he still couldn't start fighting when he got to the place, which made him feel uncomfortable, and he hated these little monkeys who attacked his harbor even more.

With this hatred, the fleet ran extremely fast, and it only took a day and a half to reach the Sunda Strait. Fortunately, the ships were finally spotted this time, and there were several scattered on the sea, leaving the port of Pasaima on the west coast, and the sails were not yet raised.

"Sail down! Enter the strait and take the middle of the waterway. Attention to starboard, prepare for shelling, solid shells! "It's a soft persimmon, Hong Tao plans to pinch it hard, until it bursts! The sailing ships that had just sailed out of the harbor did not know the flag Hong Tao, but the type of ship Hong Tao knew, the same as the ship that attacked the port of Malacca. What's so polite, on Javanese territory, driving Javanese ships, you're either Javanese or Javanese friends. The enemy's friend is the enemy, Hong Tao's logic is like this, so he wants to take these ships first.

Since the development of naval artillery to the equipment on the ship, there has been a lot of drills, and exercises have been carried out almost every day, but it is the first time that the real bombardment of a sailing ship has been carried out. In the past, a wooden plank was set up on the shore as a target, and there were no wealthy sailing ships in Jinhe Bay to be used as target ships, and the board of directors who built new ones would not agree, and Hong Tao would not agree to them, it was too wasteful. Now is the right time, let's think of it as a live-fire exercise, and let the gunners and crews see how powerful the cannon really is at sea. In fact, Hong Tao himself wants to see it, and the actual fight and watching the movie is definitely not an effect.

For the fleet that suddenly appeared, the four ships on the opposite side were obviously a little surprised, but they didn't panic too much, at least they didn't turn around and run, but gave way to the middle channel and leaned slightly to the left. In this way, the two fleets passed by, about sixty or seventy meters apart, and the faces on both decks could be seen.

"Open the gun!" Hong Tao stood on the stern with his hands behind his back, visually measuring the distance of the ships opposite, and when the two sides were still more than a hundred meters apart, he gave an order to mercy.

"Open the gun!" Instead of shouting at the mast this time, Mercy turned around and shouted at a large copper tube like a trumpet flower behind him. This is another invention of Hong Tao, the microphone! The gunners, especially those on the lower decks, could not hear any orders from the deck at their posts, even if they did not fire their guns, and there were one or two decks in between. But they had to hear the captain's orders, and was there a quicker and more practical way than to have people run back and forth to convey them? Others don't have it, Hong Tao does.

He had the shipwrights install a trumpet in the stern, with copper pipes underneath, extending into the two gun decks below, with another flare at the exit. In this way, if someone shouts at the horn from the stern, the gun commander on the lower deck guarding the horn will be able to hear the order clearly. In addition, Hong Tao also used his tuner's skills to test the thickness of the wall of the copper pipe, and found the most favorable thickness of 100 Hz to 700 Hz resonance, and made reeds into the pipe to play the role of a megaphone. This frequency range is the general frequency response from the middle and low to high registers of men, excluding overtones.

"Aim for the waterline position! Feel free to shoot! Hong Tao added another sentence, and then stared at the sailing ship that was getting closer and closer, and did not squeak. The captain doesn't have to worry about when to fire the gun, there is a gun commander on each gun deck, he will be responsible for aiming, and once he has the right to fire, he will give the gunner the order.

Each gun was equipped with six gunners, two of whom were full-time gunners and the other four were temporary by other sailors. Doing so will certainly reduce the rate of fire of the artillery, but it will save a lot of manpower. At present, Hong Tao does not need to face artillery battles on the water, so he does not need a rate of fire, as long as he can fire safely, he is qualified. If you want the naval guns to reach the highest rate of fire, that is, the record of three rounds in two minutes set by the British Navy, then the 155 caliber naval guns need to be equipped with fourteen full-time gunners, and the 135 caliber naval guns must also be equipped with nine full-time gunners, which can increase the number of people on the Golden River several times at once, which is meaningless.

The firing and reloading of this kind of front-loading artillery is very, very cumbersome, and it is not about putting in a projectile, a shell, and then a little fire is done. After each shot, you have to use a wet cannon brush, which is a cloth-like thing, to poke into the barrel of the cannon, extinguish the sparks after the launch, and then get out the residue, and then put the firing cake in, stuff the shell with the cork tray into it, and stuff a cork plug on the outermost part of the cannon, and poke it into the barrel with a pier cloth. This cork not only increases the chamber pressure, but also prevents the shells from the barrel from falling out if the ship rocks too much.

At this time, the gunner in charge of ignition and firing also used an iron hammer to poke down from the fire door, smash the medicine cake, and pour some gunpowder powder on it. Wait for the gunner to give the order to open the cannon, and then the red-hot iron rod can be inserted into the fire door to ignite the gunpowder surface, thereby igniting the cannon chamber to fire the medicine cake and exploding the shell. To complete this process in less than a minute, everyone in the gun position needs to be very, very skilled, and it is impossible to achieve it without long hours of hard training.

In the past, the artillery on the Jinhe had to be fired once in two and a half to three minutes at the earliest, but the accuracy was quite high. When he was playing with the Puyol brothers on the Mouse Superman, the old twin twins once said that the French Navy had a very simple and very effective way to improve the accuracy of artillery shooting, which Hong Tao remembered and now took it out, adding a little divine power to his already almost possessed divinity. After many trials, this method is indeed very simple and practical!

How did the French Navy improve the firing accuracy of its artillery? It was especially simple, they tied a shell with a rope and hung it on a beam on the deck. The position of this hanging shell was not chosen at random, but corresponded to a white line below. The French gunner used the oscillating relationship between the shell and the white line below to determine the ship's oscillating state, and then issued the order to open the cannon. As long as the gunner's observations were accurate, and the gunner's reaction time and a one-second delay in ignition, the shot would be very similar to shooting on flat ground, and would have eliminated a lot of interference from waves and hull shaking.
