In water warfare, the most commonly used tactics are ramming and hand-to-board combat.

A ramming is the use of an object in front of a ship to cause great damage to an enemy ship.

In broadside combat, soldiers jump onto the enemy's ship and engage in hand-to-hand combat after approaching the enemy ship.

Although some ships were equipped with artillery and other equipment, the way of fighting did not change because of their short range and low power.

With the increase in the power of naval guns and the improvement of ship maneuverability, broadside warfare was gradually replaced by battle line tactics.

However, there is a premise on the battle line, that is, the artillery firing technology must be high.

It's not the kind of film and television dramas that simply put a few shots and resign yourself to fate if you don't hit it.

In order to show the strength of his sailors to Matsuura Nobuzhen, Li Dan and others, Yang Chengying bought a merchant ship and used it as a target ship for exercises.

With Yang Chengying's order, the new ship that Ning Wan and I organized shipwrights to transform on Dachangshan Island, the Fuwei, sailed out of the port under the command of Geng Zhongming.

The ship was equipped with 23 guns, all of which were bronze Hongyi cannons unloaded from the Karrick warship. The original Karrick warship became a transport ship, carrying only cargo.

For the first time, the Forway, which resembled the Galen ship, adopted line tactics, using the sailors' skillful artillery shooting skills and grasp of the wind direction to fire at the target ship.

After only one round of attack, the merchant ship sank to the bottom of the sea.

Subsequently, Geng Zhongming commanded the ships to shell randomly designated objects on the shore, and they also hit seven out of ten guns.

As a result, whether it was Matsuura Nobuzhen or Li Dan and others, they were all taken aback.

"What a great shooting skill."

Li Dan smiled lightly and hugged his fists and asked, "Yang Shuai, how did you do it?" ”

"Let each of them read and write, learn arithmetic, understand the basic principles of geometry, and they will be able to do it."

Yang Chengying said with a smile.

Hearing this answer, Li Dan asked again: "Yang Shuai is doing this, isn't he afraid that your subordinates will desert and tell others all your secrets?" ”

"Li Gong's worries are not unreasonable, but if he gives up the pursuit of sailor training because he is worried about this matter, it is too unworthy."

Yang Chengying had another reason not to speak.

It has a lot to do with the environment of East Asia as a whole.

Houjin did not have a water master, and there was no need and place for a water master. The sailors of the Wa Kingdom were originally not highly skilled, but with the advent of the lock-up order, the sailors gradually lost their skills.

Not to mention the sailors of the Li Dynasty, the army did not understand it.

The Ming Dynasty did have a water division, but it lacked sufficient motivation and financial resources to develop.

The sailors under his command had no place to go.

Therefore, he did not worry about defecting to the enemy.

"Although the artillery is powerful, it depends on the bravery of the samurai in close combat!"

Matsuura Nobuzhen obviously didn't want to lose face, "If Yang Shuai doesn't mind, let's have a fight at sea." ”

"Yes." Yang Chengying agreed very happily, "In order not to hurt the harmony of the two families, neither of you nor I should use sharp weapons, is it okay?" ”

"No problem!"

Matsuura Nobutada is very confident, and the sailor of his own domain has been raised for so long, and he can definitely fight.

Each side sent a warship, crashed into each other on the sea, and then engaged in broadside fighting.

Then he opened the eyes of the people who were watching.

When the Perak soldiers boarded the boat, they did not fight alone but in groups of three or four, with two men holding shields and one or two men carrying long weapons.

No matter how you scream, they just don't go one-on-one with you, and form small groups to drive Matsuura Nobusada's people into the sea one by one.

After boarding the ship, it is not a blind fight, but a very targeted control of the important position of the ship, and then sweep away the remnants of the enemy.

This reminded the Japanese of a not very pleasant memory.

"Are you still fighting?"

Seeing the result, Yang Chengying asked.

Matsuura Nobuzhen hung his head and said, "Don't fight, your sailor is really powerful." ”

"Alright, Mingjin retreats." Yang Chengying signaled to the flag officer.

The flag bearer waving the flag.

Halfway through the battle, the sailors heard the order and immediately evacuated from the ship in an orderly manner.

When everyone saw it, there was no need to continue.

Li Dan was secretly glad that he didn't really hold on to the other party and competed with the other party.

At the end of the exercise, when he withdrew from the field, Yang Chengying said the purpose of his exercise.

"I'm leaving. On the occasion of parting, please watch a play together, which is my gift. ”

Yang Chengying smiled and said, "If you feel offended, please Haihan." ”

Matsuura Nobuzhen smiled bitterly: "Your Excellency's sailor is so mighty that people will never forget. It is a great honour to be your friend. ”

"Where, it is my honor to cooperate with Matsuura-kun and Li Gong." Yang Chengying said.

"In the future, we will cooperate more and make the business as big as possible."

"It's a deal."

Yang Chengying stretched out his right hand with his palm up.

"It's a deal!" Nobusada Matsuura stretched out his right hand and held Yang Chengying's hand.

Li Dan also stretched out his right hand and put it on the back of Matsuura Nobuzhen's right hand: "A word is a certainty." ”

The three parties shook hands thoughtfully, and only then did they officially form a cooperative alliance.

According to the historical timeline, Yang Chengying estimates that this alliance can last for at least two to three years.

This is quite valuable for Yang Chengying.

Training a strong sailor requires a lot of time and combat experience, and two to three years is too precious.

In this way, it made Gui Bo Xuanfang, who had always been unequal, very disappointed.

He feared that Yang Cheng would find a more suitable trade partner and abandon the Tsushima Domain.

On the way back, Gui Bo Xuanfang took the initiative to find Yang Chengying: "Yang Shuai, after arriving in Tsushima Domain, can you rest for a few days?" ”

"Rest? Why? Yang Chengying asked.

"The feudal lord wants to make a blood alliance with Yang Shuai and form a brother, I don't know if it's okay?"

"Absolutely."

Yang Chengying promised to be as cheerful as ever.

Anyway, this kind of thing is not counted, so let Tsushima feel at ease, why not.

This is what the average person thinks.

Yang Chengying doesn't think so, he won't bow down to anyone.

"Really?" Gui Bo Xuanfang was not at ease.

"What did I lie to you. It's just ......"

Yang Chengying changed his words, "There is a saying, with all due respect." ”

"You say."

"You and I are old friends, you should know that the relationship with me should end immediately."

"What do you mean by that?"

"I don't have the intention of harming you, and there is no need for it. But you have been between the shogunate and the Li dynasty for a long time, and the balance of relations is delicate. If you put too much emphasis on my side, it will make the shogunate suspicious of you, and that will not be good. ”

"Well...... this"

Gui Bo Xuanfang only wanted to reach an alliance with Yang Chengying and maintain his own interests.

Now after listening to Yang Chengying's words, I suddenly feel that his words are very reasonable.

This kind of action cannot be made until the moment of crisis.

After thinking about it again and again, Uncle Gui finally took back what he had just said about "righteousness".

After this episode, Yang Chengying had nothing else to do, and after the supply of Tsushima Island was finished, he went to the Li Dynasty.

After receiving Zhang Cunren and his soldiers in the Li Dynasty, he returned to Jinzhou Town.

Time inexorably came to June of the fourth year of the Apocalypse.
