Generally speaking, the larger the boat, the less agile it is and the slower it will be. Just like the most famous building ships in Jiangdong, the speed is far less than that of smaller ships and fighting ships. Of course, this also has something to do with the construction of the ship.

As the most famous and core ship type in Jiangdong, the building ship has now been slowly eliminated from the battle sequence by Yuan Shu, except for the caravans that cross the river are still more often used, and have gradually disappeared in the navy.

The reason is that although this type of ship can accommodate a large number of soldiers and is very powerful in mainstream broadside battles, it has too high a center of gravity. Building a three-story or five-story "building" on the hull of a ship is naturally no problem in the gentle river, but it is extremely dangerous in the rough sea.

The type of Koto ships has now been improved and is slowly approaching that of modern sea ships. After all, although Yuan Shu was a scumbag before crossing, he still had at least some knowledge, even if he didn't know the specific situation of the Galen ship, a great weapon of naval warfare, he had seen the model of this thing in many places.

In line with the idea of trying his luck, Yuan Shu directly asked the painter to draw the model of the sea ship in his impression and handed it over to Lu Lao, who was in charge of shipbuilding. In recent years, with the summary of problems found by the navy in the continuous navigation of the sea, the Jiangdong sea ships have become closer and closer to the appearance of modern sea ships. Instead of stupidly adding so much burden to the low hull like building a ship, the hull is raised to lower the center of gravity, the cabin is embedded in the hull, and the hull is constantly moving closer to the streamline.

However, after so many years of shipbuilding, it is still difficult to change the "bad habits" of shipbuilding, resulting in the progress of Jiangdong sea ships is still very slow, and it takes a lot of energy just how to apply steel to shipbuilding.

Demand determines the direction of development, and since naval forces have always been used in river warfare, the Han people of this era are not so much about building ships as they are about how to build cities on ships without sinking. For example, the building ship is to build a building directly on the ship for garrison, and the fighting ship is to build a female wall on the ship for defense. These ships are not suitable for sea warfare at all, except for Gan Ning and Jiang Qin, who rely on the talent of the legion, the other fleets have always sailed along the coastline to avoid wind and waves.

Therefore, Jiangdong's seagoing ship technology basically started from scratch, relying entirely on the sketch given by Yuan Shu, and constantly making exploratory improvements on the basis of the ship's technology. Progress has progressed rapidly over the years, but many of the techniques are still imperfect today, and cannot be compared to those of the Kushan, who came from orthodox naval warfare.

Of course, Kushan's navy also had its limitations. Because the Kushan navy was basically used to escort merchant ships and trade, and the enemies they faced were also pirates who came and went like the wind and had a single means of attack, so their warships were large in size, and their speed and collision ability were very good, but they lacked long-range attack methods, and their functionality was not strong, and they were not as diverse as the types of warships of the Han Dynasty.

And now Zhang Yun, seeing that such a large warship has a speed of more than the number of Han warships, he is naturally quite itchy.

The reason why Gan Ning was able to beat Cai Mao and become the world's number one naval army general was because of his speed. In water warfare, speed is much more important than on land. is as strong as Cai Mao, and when he encounters Gan Ning, he can only stare dryly, he will be kited when he rushes up, and he will be chased and beaten when he retreats, which is even more shameless than the archers.

"Your Majesty really had foresight, fortunately we didn't make rash contact with Guishan, otherwise Guishan's army would really be a trouble." Zhang Yun couldn't help but rejoice. Then he sighed with a little regret: "It's a pity." If it weren't for Kushan's giant warship, it would only appear in a naval battle of more than 10,000 people, so I really wanted to get one. The protective measures of Guishan are also strict! ”

Ships are such things that are extremely slow to improve and transform themselves, but as long as they can get a mold, it is much easier to imitate, so technical protection is extremely important, and it is generally necessary to sink or damage the ship even if it abandons the ship and escapes.

"When the difference in strength is not too great, the first thing to be exposed is the prey, and we are the hunters." Beside Zhang Yun, Kuai Yue, who was dressed in black, said coldly.

"Xeno, you said that, aren't we playing the role of hunters now?" Zhang Yun smiled slightly.

"Zirou has become a big official, your talent is not inferior to your brother, why don't you participate in political affairs like him, but come to the army?" Zhang Yun asked suddenly.

"I'm not the right person for politics. My brother is kind and benevolent, and I am treacherous and good at scheming, if I want to surpass my brother, I have to find another way, and Guishan is the best springboard for my rise. Kuai Yue's eyes flashed with the same light, and he said in a deep voice.

"I'm afraid it's not only for you, but Guishuang is also the best springboard for me and Deju." Zhang Yun also sighed.

Since Jingzhou was taken by Yuan Shu, and he and Cai Mao surrendered, the position has been extremely awkward. In terms of the fact that the naval army is not as good as Gan Ning in combat, and the sea is not as good as Jiang Qin, the most embarrassing thing is that the entire Yangtze River is controlled by Yuan Shu, and they have no place to use it at all. And the north is not a stage for them to show, even Gan Ning, who is good at speed, was blocked by Yuan Shao looking for an opportunity, and they, the "short-legged", did not dare to coil in such a rootless place. Cai Mao and Zhang Yun have faced this embarrassing situation of no opponent and no battlefield in recent years.

"But I'm afraid we will have to lie dormant for a few more years, and the domestic situation will not be unified without three or five years. Yuan Shao's foundation is still too thick, and there are two heroes Liu Bei and Cao Cao who are stubbornly resisting. Kuai Yue reminded.

"Dejue and I both understand this, and we're both ready. But we haven't been able to do it for a few years, but that doesn't mean we don't have anything to do, and these pirates seem to be good people. Zhang Yun said with a smile.

"That's true. Originally, I came here to make a move on the generals of the Kushan Navy, but now it seems that I should target these pirates for the time being. Kuai Yue sighed lightly.

Hearing this, Zhang Yun only felt the corners of his mouth twitch: "Xeno, you're joking!" ”

"Nope." Kuai Yue said calmly.

"Do it to the generals of the Kushan army? Do you know the risks of doing so? Once exposed, you and I will die a hundred deaths! Zhang Yun said excitedly.

I thought Cai Mao would be crazy enough to do this, but I didn't expect that the real madman was the guy in front of him. looks quiet and elegant, but thinks about such crazy things.

"If it is exposed, it will not be redeemed, and if it is not exposed, it will not be the work of the world. Didn't we do the same thing this time? Kuai Yue's face was as usual, and he said with a faint smile.

Sure enough, Zirou was right. You're a lunatic! Looking at the young man who was close in front of him but out of reach, Zhang Yun suddenly thought of the conversation that Kuai Liang had asked him to talk to Cai Mao before leaving Jinling, and a trace of regret flashed in his heart, and he said in hindsight.

"In a peaceful and prosperous world, what is needed is good strategy. And in today's troubled times, what is needed is a madman! Kuai Yue smiled indifferently, and his smile revealed incomparably hideous.
