Jiang Yan shook his head, wondering: "General, don't you know that the water surface is already bumpy, and it becomes even more choppy when encountering wind and waves. Not to mention the accuracy of the crossbow arrows, just loading and stringing the arrows is more difficult than on the ground.

Often trebuchets and bed crossbows are only installed on wide-hulled building ships, and bed crossbows are installed on battleships and galley battleships. There are still dozens of them, and I'm afraid they are not enough!"

Yunfeng pondered for a moment and said slowly: "The problems we encounter now are nothing more than two aspects. One is to try to improve the operating efficiency of the crossbow. According to this general, it is not due to improving the traditional pull-type stringing into a winch type.

To wind the string, I will return to Shanggui and immediately ask Mr. Jiang to start. Based on the many ingenious techniques of Tianji Sect, I think the problem is not that big. The second is to improve the stability." After saying that, Yunfeng waved back.

One of the guards offered a spring knowingly. Yunfeng took it and handed it to Jiang Yan and said, "If this thing is installed on the four corners of the bed crossbow, does Jiang Gong think it will be effective?"

Jiang Yan frowned and did not answer immediately. He picked up the spring in his hand. Dou Tao also curiously moved his gray head, looked left and right, and tried to pull it with his hands. This spring was made of steel.

The strips were rolled up, so Dou Tao used his strength.

The spring slowly opened, and the spiral stretched wider and wider. Dou Tao felt that it seemed to have reached the limit, so he instinctively let go.

There was a muffled sound of "Bang!"! The spring retracted violently! Then, there was another "Ouch!" a cry of pain. It turned out that Jiang Yan was caught off guard and was hit by the bullet! The spring was also thrown subconsciously.

aside.

Jiang Yan gasped, rubbed his hands and said displeasedly: "What are you doing, you old guy? You want to scare people to death!"

"This...this..." Dou Taofu looked at You Zi's swinging spring in shock, and was speechless for a long time.

"Hmm!" Yunfeng suppressed his laughter. He picked up the spring and explained: "Mr. Jiang, Mr. Dou, this thing is called a spring. It can store power and convert larger bumps into smaller elasticity.

The carriage that came with me was equipped with springs, and the bumps on the carriage were reduced a lot. Would it be useful if we could use this to fix the crossbow arrows?"

Jiang Yan was rubbing his hands while contemplating. He suddenly relaxed his brows and said happily: "Yes, if Jizhong can modify the crossbow arrows in time, this method is indeed feasible! In this way, the long-range lethality of the battleship will be multiplied several times.

Add!" As soon as he finished speaking, his old face showed a bitter look, and he said hesitantly: "Now Jiangzhou has to build both a city and a naval army, and money is already stretched thin. To install crossbows, it will inevitably increase investment, and I'm afraid it won't be enough.

!”

"It's okay!" Yunfeng smiled and took out a book from his arms, handed it to the front and said, "You two will know it once you take a look."

Jiang Yan took it and opened it doubtfully. Suddenly, the old face became extremely beautiful. Dou Tao leaned his head again in confusion. For a moment, he was stunned!

Jiang Yan asked in disbelief: "General, are these all reserved for Jiangzhou?"

Yunfeng nodded and said: "Half of it will be used to build the city in Jiangzhou. The other half will be used to build the navy. If it is not enough, I can find another way to raise money."

Jiang Yan waved his hands repeatedly: "Enough, enough, so much money is enough to create an invincible naval army!"

Yunfeng raised his hands in satisfaction: "Then I'll leave it to Mr. Jiang to take care of it. In addition, I have another suggestion. Since the bed crossbow has a heavy weight, installing it on the deck will make the center of gravity of the ship higher, which is not conducive to the stability of the warship.

Therefore, the crossbow arrow hole can be opened with a skylight on the side of the ship and installed in the cabin. Does Mr. Jiang think it is feasible?"

Jiang Yan frowned and stroked his beard and said: "General, now warships have watertight warehouses. Although safety is increased, it is at the expense of cargo space. If the bed crossbow is placed in the ship's warehouse, I am afraid that one ship will

The warship cannot carry much food, grass and baggage."

"Good question, Mr. Jiang!" Yunfeng nodded: "This issue has already been considered by the general. Increasing attack power must be at the expense of cargo capacity. In fact, it is not difficult to solve. Ordinary ships can be organized as transport ships and

Supply ships are specially designed to carry food, fodder and supplies to follow. According to this general's opinion, the Navy should develop in the direction of specialization and refinement. The only role of warships is to fight, and they should not take into account other functions!"

Wonderful!" Jiang Yan couldn't help but high-five! Dou Tao's eyes also burst out with a sparkling light!

During the conversation, the group of people had arrived at the sheltered bay. This was Yunfeng's special request to build an embankment by the water for berthing of ships.

"Huh?" Yu Wenjun, Zhang Lingyun and Su Qizhen all looked at each other in surprise. Yu Wenjun couldn't help but asked: "Mr. Jiang, why is the style of this battleship so strange? Aren't all battleships supposed to have square heads and square bottoms? So

Are everything here pointed and pointed?"

"Haha~~!" Jiang Yan stroked his beard and said with a smile: "This was all the general's idea. Nowadays, all warships use keels as frames to reinforce the hull, and are also equipped with watertight compartments to prevent partial rupture of the hull.

Other parts have also been improved, so it looks like this. I thought it was strange at first, but after a while, I got used to it, and it is much neater than those big guys with square heads and square brains!"

"Oh! Thanks for the advice, Mr. Jiang!" Yu Wenjun saluted, but suddenly remembered that this was Yunfeng's idea. He couldn't help but rolled his eyes at the man and said unconvinced: "General, how effective can your design be?"

Yunfeng said nonchalantly: "Let's board the ship and have a try, and we'll find out. Is Mr. Jiang ready?"

"It has been prepared and can set sail at any time. General, please board the ship!" Jiang Yan stretched out his hand to signal, then turned around and shouted: "Put down the gangway!" The sailors on the ship immediately set up the gangway and pushed it steadily to the shore.

What Yunfeng and others boarded was a galley battleship. A thick iron vertebra was installed on the bow of the ship, which was looming in the river. Hundreds of large oars protruded from both sides of the hull, turning up patches of white waves. Currently, there are ships that have been built.

Nearly thirty ships, including sterns and fighting ships, formed a small fleet and sailed upstream.

"It seems that the speed must be a little faster!" Yu Wenjun praised the new warships as he carefully realized the difference between the new warships and the traditional warships.

Yunfeng ignored her and continued to look forward. Yu Wenjun was quite bored. After a while, he exclaimed: "Look, there is a fighting ship floating down the river in front of you!"

Yunfeng winked at Jiang Yan, and Jiang Yan immediately waved back. Suddenly, the oars on both sides were flying, and the galley warship slightly adjusted its direction and collided head-on with the fighting ship floating slowly in front!

Yu Wenjun realized something was wrong and reminded him repeatedly: "Oh, the ship is about to collide. General, why are you still standing still? Mr. Jiang, hurry up and ask someone to turn around!"

Yun Feng still said nothing, while Jiang Yan and Dou Tao stroked their beards and smiled. Although Zhang Lingyun and Su Qizhen were puzzled, they saw that there was no one on the boat coming from the opposite side, and the three people looked confident, so they felt a little worried.

There was some speculation.

Yu Wenjun's expression changed rapidly, and she wanted to run away. However, with so many people on the boat standing still, she didn't feel comfortable escaping alone!

"Fight!" Yu Wenjun clenched his little fists and looked at the approaching battleship with wide eyes! Although he made up his mind, his face turned pale, and his two little hands unconsciously squeezed tightly.
