Lock The National Destiny: Start Integrating The Dragon Clan Summoning System

After listening to Merry's professional explanation, Yu Nan seemed to understand whether he understood or not, thinking that it would be better to let Jessica listen to it, so he hurriedly got on the boat with Merry.

After getting on the boat, Yunan was still looking around curiously, the deck width was about nine to ten meters, the bottom of the mast was full of ropes, and the hard sails with bamboo ribs were folded at the bottom of the mast.

Yunan took a closer look at the mast and sails, and always felt that something was wrong.

At this time, Jessica came over and asked Melly, "Why is this sail so strange?" and Melly

smiled and replied, "It must be different from your usual soft sails, this is a hard sail."

Jessica exclaimed in surprise, "Ah, I've only seen it in the history of sea ships, so it's no wonder it's a little familiar, but it's the first time I've seen the real thing."

Although the ships of the Elves of Joe and their clan were older, they had always used soft sails, and when they saw the hard sails, they were also amazed, and asked, "What is the difference between

this hard sail and the soft sail?" Melly was about to answer, but Jessica preemptively said: "I have learned before, this hard sail and soft sail have their own advantages, the hard sail is relatively easy to make, and the material requirements are not high.

Ordinary fabrics are sufficient, and in case of emergency, even straw mats and reed curtains can be replaced, and even if the sail surface is slightly damaged, it can continue to be used, and it is also convenient to repair temporarily.

Melly looked at Jessica in surprise, she didn't expect that this girl was not only beautiful, but also knew a lot about ships.

Jessica continued: "Actually, the main advantage is that it can rotate around the mast, which makes the sail surface wind efficient, and there is even a saying that the hard sail can use the wind from all sides.

Even in the case of oblique headwinds, the angle of the sails can be adjusted at any time to make the boat sail in a zigzag pattern, which is not possible with soft sails.

"Yes, it's especially suitable for small teams like you, it's extremely easy to operate, and it doesn't need to be adjusted as often, saving the operator's manpower, have you noticed

," he continued, pointing to the mast, "This kind of sail has no sheaves, no complicated cables and ropes, and the average person can do the work of retracting and releasing the sails."

And it's fast, and when you're in danger, you can even cut the main rope in a few seconds, but it's more laborious

to lift the sail," Melley said, demonstrating for a moment, and tried to lift it with both hands, but he didn't move, gasping for breath: "There are ribs in this sail, although it is wooden."

But there are many of them, so the weight is very large, and not to mention the manpower required to raise the sail, it also requires a strong person to control.

Charlie limped over and tried to do it, but it was not an ordinary person, although it was still a little laborious, but he lifted it smoothly, he turned his head and nodded at Yu Nan, indicating that it was completely controllable.

Yu Nan was relieved when he saw this, Melly's eyes were round, still surprised by Charlie's brute strength, but Jessica picked up, "But there is a fatal flaw, the price of hard sails is too much weight, which limits the carrying capacity of the ship, and the key is that the speed cannot get up, compared to soft sail ships, it must be far behind."

Merry nodded and said, "That's right, if you want to convert it into a soft sail, it's a big problem, and it may only be solved in the capital of the seven waters."

Yu Nan smiled mysteriously at everyone: "This is not a problem at all for the time being.

Jessica was very confident in her knowledge of navigation, and was about to say something, but Yu Nan interrupted: "Let's not talk about this for now, let Merry introduce the others."

Jessica looked at Yunan strangely, took the words that came to her lips, and swallowed them back.

"I have learned a lot from the design drawings of this ship, and for the first time I know that there is also the ingenious design of watertight bulkheads, and there are ten in the entire hull, which are mainly used for..."

Jessica sneered, and when she said that you couldn't do it, she triumphantly discussed it with Merry.

"This watertight bulkhead increases the structural strength of the hull and can play a role in reinforcing the hull.

Jessica was surprised to hear this, and asked Melly, "Then tell me what other good things are on this ship?"

"I just told Yue Nan that the water board has another wonderful use, and he can use it in combination with this hard sail and rudder to make the boat have the ability to sail in all wind directions.

Jessica kept asking Melly questions, and Melly patiently answered them one by one.

An hour later, Jessica was finally satisfied, and let Melly leave with a smile, and Charlie couldn't wait to glue Melly again, it turned out that he was asking about the artillery equipment.

"There is a fixed gun emplacement in the bow and stern, and because the ship is inclined to exploration, there is only one gun window on the side of the ship, and there is a movable gun on the deck," said May, gesturing to a corner of the deck, where there was a large one, wrapped in a large piece of tarpaulin.

Charlie rushed away impatiently, and Melly shouted at Charlie with a smile: "Attention, fire a cannon on the deck, install it on a fixed track, the hardwood at the end of the track can play a role in counteracting recoil!" Charlie

studied the cannon and said disappointedly: "This cannon is not very good, the range is definitely insufficient."

"I can't help this, I can only build ships, not cannons, just these few guns, but also a few years ago with great difficulty, if you want to change to a new one, you can only go to the big town to look for it."

And the better ones can only be bought on the black market.

Charlie suddenly realized, and went to get busy with the green, and Joe found Merry again, and asked him to take him to the cabin.

Yunan stood by the guardrail on the side of the ship, and the voices of his friends echoed in his ears.

In this voice, representing happiness, excitement, and even happiness, Yu Nan looked at the endless sea, and silently said in his heart: "Great voyage, I'm coming

!" At this time, Jessica walked up to Yu Nan, with a sweet smile on her face, and whispered to him: "Yu Nan, with this boat, we can finally set off and go to find that place!"

Yu Nan suddenly looked up at the sky, his gaze seemed to have crossed time and space, and he opened his mouth silently, as if he was talking to someone else, and he shouted loudly in a voice that only he could hear

, "Don't worry, I've already started to set foot on the way home!"

At the same time, the sailors on the warship were busy, waiting for the commander to give the order, and they were going to open fire on the unknown incoming ship.

Suddenly, a black shadow shot out from the sea, and the sailors on the deck were startled, and then there was a commotion, looking at the comer in a daze.

The black shadow was still in the air, and I heard him snort coldly, "Water gun!"

As soon as the words fell, there was a pop, and something spat out from his mouth, flying out like lightning.
