Looking at the kind of card drawn by Li Hang, Zhou Yurong was also a little stunned.

It's not just a piece of content.,It's written with a big title and an illustration.,There's an effect below.。

Although it will definitely be a hassle to make, but what is this kind of thing?

This is a card, and you need to find some hard paper for this kind of thing, so you can use copperplate printing, and then you don't need to consider the popularity of this kind of thing, and you can directly print thousands of sets to use some public events, or even some activities, to promote these things.

In this era, there is not a lot of entertainment life, and there is no more entertainment time, but this running group is a little different, which requires a lot of time, and you can continue to play. But more importantly, this thing can gather a lot of people to play.

Just leave this entertainment matter to Zhou Yurong to do, anyway, this thing is just a gadget at best.

Li Hang doesn't care about this now, but the first ship in his shipyard has been completed.

Although it's just a fishing boat. But this makes Li Hang still very concerned.

Because this is no ordinary fishing boat.

Rather, it's a catamaran.

What is called a catamaran, it is spliced by two hulls, locked by a wooden plank in the middle, and these two hulls can be installed with fishing nets, as long as the trawl nets are poured, what fish can not be caught. It's much more efficient than casting a net.

Originally, there was nothing, but Li Hang was curious about how this thing should be waterproof.

In modern times, all kinds of ships and ships are integral steel structures, all of which are made of special steel, and there are no gaps on the surface.

But this era is different!

These ships in this era are made of wood, and ships made of wood, no matter how carefully you make them, there are gaps between the wood and the wood.

How to ensure that this gap will not seep water.

This is what Li Hang is curious about.

Following Wang Dali and others to the shipyard, Li Hang saw the first catamaran fishing boat.

The resistance of this kind of fishing boat is not very good, but it is enough to catch fish when the wind is calm, and even if there are real waves, you can immediately untie the connecting plank in the middle and turn it into a monohull and go quickly.

Seeing that the ship was still relatively new, Li Hang walked over curiously. "How does this ship prevent water seepage?"

The ship has a clear idea of its own student design.

First of all, the pointed bow of the ship, and the overall design of the ship will be slightly biased towards stability, the stability of this kind of ship is very good, and the sailing speed will not be bad, but in the same way on this kind of boat, Li Hang saw some interesting things, such as sails that can be combined.

This kind of thing is used in a small boat, which is a bit wasteful, but Li Hang saw a good thing in this thing.

A thing for positioning.

There's a compass on top of this.

This is a natural magnet.

It's not hard to find, but I've only said it myself.

Now these students of their own are actually using it here.

"Interesting!"

The students on the side were excited. "Master, all the waterproofing here is made of tung oil, after this boat is manufactured, we will fill this gap with cloth strips, and then brush tung oil repeatedly, and now we are going to use this fishing boat to dry. After drying in the sun, brush tung oil again until it no longer seeps water. ”

I see.

Li Hang nodded secretly, this is the original anti-seepage method.

But it's a little crude.

But for Li Hang, it's just practical.

It's just that in this way the cycle of shipbuilding is lengthened.

There is no doubt that it will take more than a year to build a big ship in this way, and such a means will be used on this, it will take more than just such a little tung oil, shipbuilding is a hard project, but for these people, it is a good thing to be able to build a big ship here.

Look at the people in these shipbuilding workshops. "What's the matter, my apprentice didn't cause you trouble, did he!"

As soon as Li Hang asked, those people immediately laughed. "No, no, Li Shangzao, the Lingtu is really smart, he has a lot of whimsical ideas, this pointed bow is what he came up with, and this catamaran is also what he came up with, saying that this is to let this fisherman catch more fish."

This shipyard is almost there, it is already very good to be able to produce this kind of fishing boat, it doesn't matter if the catamaran fishing boat is a monohull, this kind of small boat is used for experiments to prove that they have the ability to build ships, and one of the more important reasons why Li Hang came here is the salt drying field here.

It's no secret that you can get more salt from the sea.

What Li Hang needs is this salt, and he also uses this salt to transport some other things.

"Caught?" Li Hang looked at his apprentice and asked in a low voice.

"Hmm!" Holding a small jar, the child, who had come to think he was just here to suffer, was now smiling happily.

This sea is fun.

What Li Hang asked them to get their hands on, they actually got it.

Not only the salt in my hand, but also the local monosodium glutamate and sea intestines, plus those seaweed and some caught fish.

Looking at these games in front of him, Li Hang was really a little surprised.

Because there's something special about this car.

Not only fish, but also some squid, Li Hang even saw sea cucumbers.

And an abalone or two.

"Tut-tut, it's all good!" Li Hang has tried this kind of thing, but in these years, it is all wild.

"Looks like I'm going to be able to eat something good tonight."

Li Hang's expression was a little strange.

The main reason why he came here was the second thing, the salt that had been transported at this time was ready, and he now wanted to see if Ying Yun could invite all the families from all over the world at this time, and he came here this time to receive this batch of salt.

This batch wants to be a good salt.

These edible salts obtained by drying and boiling repeatedly are the killer features prepared by Li Hang.

The aftershocks are terrible because there is a salt mine, but if you take salt from the sea, you can get more salt this way.

And Li Hang does not plan to use this salt for sale, but plans to process it.

"It should almost be ready to go." After dismissing all the people around him, Li Hang asked people to pull out a covered carriage from the back carriage pile.

The carriage looked like a normal carriage on the outside, but the contents were quite bulky, and it could be seen from the deep wheel marks of the carriage that the things on it were very heavy.

Li Hang attaches great importance to this.

Sent the car to the beach.

After everyone dug a pit for protection, Li Hang let them go.

This was the first test of such an artillery.

Although steel was only rudimentary, it was possible to build a large cannon.

Removing the rainproof canvas and tearing off the black cloth that covered it, Li Hang filled it with gunpowder according to the steps.

When the amount of gunpowder is sufficient, the spherical projectile begins to be stuffed.

This is also a by-product of the time of casting.

It's just a little smaller than this barrel.

The walls of this huge cannon alone were more than ten centimeters.

This is not Li Hang's waste, but he is really afraid of blowing up.

The first time he made this, he was really worried, so he chose the most suitable way in terms of craftsmanship.

As for the weight, this is no longer in his consideration, other calibers and thicknesses, this kind of thing can be slowly tried and improved in the future.
