At this moment, Wang Yong had a lot of doubts in his heart.

How do they know here? And how did it get in?

Surrounded by brothers......

How can these people be so elusive that they appear when they say they appear......

Anyway, he didn't seem to see when they left yesterday......

Are the guards in town so weak?

Although Jiang Gongzi is his own person, but now is a special period, and he has to guard against outsiders.

No, he'll have to remind his brothers to step up their guards......

Just thinking about it, Jiang Yao interrupted his thoughts: "Where are you going in such a hurry?" ”

Wang Yong came back to his senses and hurriedly said: "Oh, these ships have a little problem, we have to find someone to repair them, otherwise it will be troublesome to delay at sea at that time." ”

Jiang Yu's eyes lit up.

I've just learned a new skill and want to try it out!

……

Wang Yong took them to find Long Hai and Miao Chunhua.

They expressed surprise at Jiang Yu's statement that he would repair the ship.

After all, in this era, there are very few women involved in sailing.

There is even a saying that "if there are women accompanying you, the navigation is not good", so Miao Chunhua could only disguise herself as a man and get on the ship before.

Later, the two gangs were established, and under the influence of Miao Chunhua, the people in Leping Town gradually lost this taboo.

But only a small number of women joined the sailing team and took care of the ship's chores.

I've never seen a woman repair a ship.

So under their shocked gaze, Jiang Yu walked around the boat and pointed out the hidden dangers on the boat one by one.

They even pointed out a place they hadn't discovered.

It was a ship that looked fine on the surface, but in fact the interior had been hollowed out.

Long Hai and Miao Chunhua stepped forward to take a closer look, knocked on the boat, and after carefully comparing it with the sound made by the shipboard next to them, they knew that what Jiang Yu said was true.

Long Hai sighed: "I didn't expect Miss Jiang to have this hand, my old dragon admires it!" ”

Miao Chunhua stepped forward and grabbed Jiang Yu's shoulder, and said with a hearty smile: "Good girl, really give our daughter's parents face!"

that they may see what a woman cannot do, but if we are willing, we will do it no worse than them! ”

Long Hai cleared his throat and didn't dare to reply, and the other people present didn't dare to speak up.

In fact, what they didn't know was that Jiang Yu was just familiar with the construction drawings of the sailboat and the principle of operation.

It doesn't add up to the difficulty of high school physics, plus perspective, where is the problem, isn't it clear at a glance?

It wasn't until Jiang Yu took the people to deal with all the hidden dangers with their hands and feet, and after checking them again, they were convinced.

After inspecting all six ships, Jiang Yu took the opportunity to make some suggestions.

First of all, there is the issue of sails.

These boats are monorails, that is, when the wind is downwind, the sails are sailed with the wind, and when the wind is upwind, the sails are lowered, and the oars can only be rocked by manpower.

Jiang Yu proposed to add two more sails, and changed the sails to face the windward side horizontally and slightly obliquely.

Jiang Yu explained to them in detail the principle of the force of the sail.

Although they couldn't fully understand the principle that Jiang Yu said, the people present were all veterans of sailing, and the method proposed by Jiang Yu was not feasible, and they could still judge.

Before Jiang Yu's words fell, an old captain said excitedly: "Okay! This way, you don't have to lower the sails even when the wind is headwind, so you can ...... well."

So Jiang Yu proposed that a "oar" could be added to the stern of the boat.

"It's like when a fish swims in the water, the tail swings left and right to push it forward, so every force the fish uses can be used to push the fish's body forward.

Isn't it a waste of effort for us to paddle to the surface and go back in a circle?

This oar is the same as a fish's tail. ”

Brand new things, the stimulation to them can be imagined, after listening to the fact that everyone did not come back to their senses for a long time, they were immersed in their own world, thinking about the appearance and function of the oar.

Miao Chunhua looked at Jiang Yu in surprise: "Sister Xiao Yu, did you come up with it yourself?" ”

If she really came up with it, it would be too powerful, right?!

Jiang Yu waved his hand and said, "No, our boat is like this, and it is much faster than just using oars." ”

When everyone heard this, someone had used it, so they hurriedly came up and asked.

"How much faster than paddling?"

"What does that oar look like?"

"Is it too late to do it now?"

……

Jiang Yu replied very patiently one by one: "We all say one oar and three oars, basically the same."

I've drawn the shape of the oar, so let's take a look......

It's definitely too late to change it now, and I've figured out how to change it, you see, here's ......."

After Jiang Yu explained in detail, everyone had a bottom in their hearts.

There is still a month to go, and the six ships have to be changed according to Jiang Yu's idea, although the time is tight, it is not impossible to do it.

So from this day on, Jiang Yu was busy transforming sailboats in the town.

Shi Yanzhi and ππ have been following.

When Jiang Yu was busy in the crowd, Shi Yanzhi was carrying a backpack with ππ on his back, squatting not far away and waiting.

Jiang Yu listened to their movements, and at the same time looked up from time to time, and when he saw that the people were still there, he continued to be busy with confidence.

Then pinch some to bring them food and drink.

Later, I got acquainted with the people in the town, and ππ was able to come out to let off steam.

One person and one mouse have to play.

often ran without a shadow, and Jiang Yu could only judge their position by sound.

As a result, one didn't pay attention, and one person and one rat plunged into the waves.

Jiang Yu was startled, and hurriedly ran over, for fear that they would be swept away by the waves.

Halfway through the run, I saw a man and a mouse, and they actually got out of the waves with their dexterity.

The water nature is much better than Jiang Yu's dog-crawling style.

Gotcha, I'm worried.

One person and one rat don't know how happy they are.

Because of the cold weather, Jiang Yu didn't let them play for too long, so he called them back.

Of course, I was tricked back with cookies.

When the two wet guys were squatting in the beach and nibbling on the biscuits, Jiang Yu pulled out two pieces of cotton cloth from the space.

Draped a large piece of cotton cloth on Shi Yanzhi, and chattered in his mouth: "Stay good and don't move, on such a cold day, you are still so happy, and you are not afraid of catching a cold?" ”

Then wrap ππ in a small piece of cotton cloth and dry it finely.

While wiping, he also chattered: "You are really amazing, in such a cold weather, you drill into the sea with two stones, he doesn't understand, don't you understand?" ”

"Squeak"

"Still talk back, look at your body hair, how difficult it is to dry, thanks to the sun today, wipe it for a while, and obediently go over there to lie on the big rock.

Dry the hair and then go to play, don't get wet and drill into the sand, and then get a pile of sand, how dirty it is......"

Shi Yanzhi wrapped himself in cotton cloth, and after nibbling on the biscuits, he squatted beside him, watching Jiang Yu wipe his body, with a hint of envy in his eyes.

Waiting for Jiang Yu to wipe the treasure hunting rat almost dry, he looked at Shi Yanzhi again, looking embarrassed.

What can this guy do?
