A bay on Matsu Island is also densely packed with boats, some of which are large and small, with six or seven medium-sized and small-sized boats, as well as six or seven bird-boats and brigs, and in addition, there are more than a dozen small fishing boats with single masts moored in the bay.

On the sea around Matsu Island, there are also some small fishing boats scattered around, and it is calculated that the mixed river dragon has at least gathered large and small boats on Matsu Island, a total of more than 30 of them.

In the bay, there is a small water village under construction, one or two hundred ragged people, under the surveillance of some pirates, like ants, are busy here, constantly transporting all kinds of materials, building this water village.

The water village is close to the beach and is already taking shape, and next to the water village, a trestle has been built for ships to dock and load and unload cargo, and another trestle is also under construction.

Behind the bustle, there was a tense atmosphere, and there were constantly armed pirates on the shore passing through the sampan of the ferry, going to and from the ships on the sea.

A number of small dhows kept coming and going in the bay and on the sea, and at noon a column of smoke suddenly rose on the southeast side of the sea.

The column of smoke came from a fishing boat beyond sea level, and at the sea level as far as the fishing boat could see, a sparkling shadow of sails appeared at this time.

As the smoke rose, the watchmen on Matsu Island immediately began to sound a rapid gong, and the pirates on the island immediately began to rush to the beach like bees that had exploded their nests, jumped on the sampans docked on the beach, and rowed towards the ships moored in the bay.

It didn't take long for the various ships moored in the bay to start anchoring and hoisting their sails, and then sailing towards the outside of the bay.

On one of the largest of them, a large cyan flag was raised, on which a large bucket of Chen characters was embroidered with white thread.

All the ships that went out to sea quickly gathered around the medium-sized ship and headed together in the direction of the rising plume of smoke.

Yu Xiaotian stood on the bow of the Sea Wolf, sailing next to Wang Hong's lucky boat, according to the previous agreement between him and Wang Hong, his ship will follow Wang Hong's ship from beginning to end, on the one hand, he can get Wang Hong's leadership and guidance, and can also get Wang Hong's protection, at the same time, he can also provide a certain cover for Wang Hong's ship, protect Wang Hong's ship flanks and rear from enemy ships.

As for the other pirates who were invited to help, they were also ordered to follow next to or behind a Shark Gang ship, and they were not used as the main combat force, but were mainly responsible for planning the Shark Gang's ships and helping Qian Lao Er and them win the conflict.

After arriving here, Yu Xiaocai knew that the Shark Gang was not as unbearable as he thought, at least there was a certain method of command and communication between them.

Their fleet was headed by Qian Song's ship, which was considered the handsome ship of their group, Qian Song led the boat in the middle of the fleet, and at the stern of the ship, a special flagpole was erected, and a small flag was hung on it, and the color of the flag was different to convey the orders given by Qian Song, and the rest of the ships observed the color of the flag hung by Qian Song's ship to determine the order that Qian Song gave to them.

Although this method is very simple, it also plays a role in command and mobilization, but it can only convey some simple orders that have been agreed in advance, and more detailed orders are a bit inadequate just by relying on the change of this flag.

Moreover, the meaning of the Shark Gang's flag order should be a secret for the Shark Gang, and this kind of thing is obviously not easy for the Shark Gang to let others know, in case the enemy can also recognize the meaning of their banner.

This is also the reason why Qian Song did not give Yu Xiaotian and the pirates who came to help him arrange the task in detail before setting off, but just let each of them follow a Shark Gang ship, as long as they keep an eye on the ship they are following and follow their actions, they will not let them take care of the rest.

It wasn't until after going to sea that Yu Xiaotian figured out about this matter, and he couldn't help but be disapproving, at the moment, those of them who came to help, at least they were friendly troops, and they didn't even let them give orders, only let them cooperate, which was not easy to operate in addition to distrust.

In addition, although the Shark Gang has this kind of flag order as a means for them to command operations, this kind of communication and command method is too simple, and it is impossible to use this kind of flag command to convey slightly more complicated orders, and the situation on the battlefield in wartime is changing rapidly, and there is no set of more practical means of transmitting signal commands, which is unimaginable for commanders.

However, he can't manage this kind of thing for the time being, but it reminds him that in the future, his strength will become stronger and stronger, and there will be more and more ships and subordinates.

So Yu Xiaotian walked all the way, pondering this matter all the way, the first thing he thought of was the flag, with the level of science and technology in this era, he didn't have to think about things like radio now, he didn't learn electronics, it was impossible to make this kind of thing, so he could only start from the simplest way, and the flag language was a means of communication, originated very early, even in this era, it has been widely used, especially the sailor, it is widely used in this way of communication.

Including the current Shark Gang adopted this kind of flag order, it is also a simple flag language, in later generations it is widely used in the military aspect of an important means of transmitting information at a distance, whether in land or naval warfare, it is a simple and effective method, even after radio has been widely used, the flag language has not been eliminated by the military of various countries.

It's a pity that he has never been a soldier before, and he has never been in contact with such a thing as a flag, but he knows a little bit about it, and he also knows that the flag language also has a hand flag, by holding a small flag, the herald waves his arms and makes different movements to transmit signals, which makes him more difficult about this matter.

In addition to the flag language, he also knew that in ancient times, sometimes through sounds such as drums and trumpets to transmit messages or convey orders, and even used to stimulate morale, but this means of transmitting messages through sound is not very useful now, especially firearms have begun to be used in a large area, and the sound on the battlefield is very noisy, with guns, drums and trumpets, and shouts...... It will directly affect the sound transmission, causing the sound to be interfered with too much and cannot be transmitted effectively, resulting in a delay in the fighter.

In addition, in addition to the daytime information transmission, there is also the problem of information transmission at night, and now in this era, the most widespread way to transmit information at night is to use the number of lanterns of different colors to convey some information, but this method also has the problem of being too simple, and it can not effectively carry more information.

On the way here, Yu Xiaotian has been pondering this matter, constantly collecting all kinds of information in his mind to try to solve this problem.

The navy flag is easy to say, it can be combined with a lot of flags of various colors, arranged into flags that represent various meanings, and then hang them, as long as people who have learned the flag language, they can know what the road means at a glance, but when compiling, it is necessary to consider more comprehensively, as much as possible to compile some flags, which requires a lot of time to consider and arrange.

Of course, you can also use the hand flag, just arrange the hand flag language, it will be more troublesome, at night, the use of lanterns to transmit the message, Yu Xiaotian can't look at it, it is best to use the lamp language, which also needs to understand the Morse code, in short, if you want to make such a set of flags and lights for transmitting messages, it is estimated that he will be busy with Yu Xiaotian for more than half a year.

Thinking about this, Yu Xiaotian felt that one head and two were big, and he unconsciously danced with his hands, which made the people on the ship feel that Yu Xiaotian's reaction today was a little abnormal, like he had drunk too much and had not woken up yet.

At this moment, the upper bucket on the top of the mast suddenly shouted: "There is a fishing boat ahead, it is smoking!" ”

Yu Xiaotian hurriedly suppressed the things full of flags and lanterns in his head, and quickly raised his eyes to look at the sea in front of him, and immediately saw a thick smoke rising at the sea level.

"Ready! Get in place! Yu Xiaotian didn't have to think about it, he also knew that Lu Dao must have encountered the sentry ship of the mixed river dragon, the other party had already discovered the traces of their fleet and began to warn towards Matsu Island, so it won't be long before the mixed river dragon's fleet is estimated to appear in front of their eyes, so he immediately shouted the order.

When the men on the ship heard the order, they immediately became nervous, and at the same time, according to the usual drill requirements, they rushed to their respective positions and began to prepare for battle.

At the same time, the pirates of the other ships in their fleet also began to shout, different from the orderly on Yu Xiaotian's ship, including the pirate members of the Shark Gang, it was obvious that they had not been trained enough, when they saw the enemy sentry ship on the sea smoke warning warning, the pirates of each ship were lively, some people flocked to the bow position, some began to climb the mast to try to see farther, and some people began to busy preparing guys, basically it was a mess.

It is not better than not knowing the road, this level is more than that of the sea wolf tribes, although there are also people shouting, but it is also the head of the soldiers everywhere giving orders, ordinary sailors and soldiers are only allowed to say a short word, and then according to the order obtained, although the personnel on the whole ship are also running back and forth, but they are doing their own thing, not chaotic at all.

After Yu Xiaotian glanced at the performance of his peers on the nearby boat, he felt a little proud, and secretly said that it seems that the person brought out by Lao Tzu is really not a shame, just with this, who of you will dare to underestimate Lao Tzu in the future?
