For Elsa and Rachel, everything about the tidal islands is incredible.

First, the water supply system of the Lord''s mansion.

Although in the long journey before, the two sisters had heard Vivian talk about this amazing thing, they still felt quite shocked after seeing the real thing.

In the washroom, open a delicate metal faucet at will, and water will flow out automatically. It''s extremely convenient.

What''s more amazing is that you can freely choose whether it''s hot water or cold water. Turn the faucet to the left, and the cold water flows out. Turn it to the other side, and the hot water comes out.

In such a cold winter, you can use hot water at any time, just think about it in your mind, it makes you feel very happy.

All kinds of new facilities in the Lord''s mansion are not only the water supply system, but also the toilet.

When Asha and Rachel saw the toilet for the first time, they couldn''t believe that it was used for excretion. If Vivian hadn''t said it, they would have thought it was some kind of "drinking water" device.

This kind of toilet is beautiful, clean and white, and the clear water in it is more clear. I''m afraid it''s hard for anyone not to think that it''s drinking water when they see it.

They put their little white butt on the toilet lid. After experiencing it for themselves, they immediately fell in love with the feeling of using the toilet.

Clean!

Convenient!

There is no stinking smell of the toilet, and there is no need to look at those dirty things, so that "poop" has become a rare enjoyment.

It is worthy of everyone''s praise, Lord, that he can invent this wonderful device.

The two sisters also witnessed the whole process of a four story high-rise building rising from scratch in the Lord''s mansion.

The terrible speed of construction It''s amazing.

In just five days, the building, which is nearly 15 meters high, has basically taken shape. It''s just for later decoration.

You know, this is not a simple wooden house with a height of 3 or 4 meters, but a "giant" stone building with a height of 15 meters. The buildings that the sisters usually see are rarely more than 10 meters high.

Very few buildings with a height of more than 10 meters are built in terms of "year", which can be as short as 1 or 2 years and as long as 4 or 5 years.

The building materials of this high building It''s a luxury.

In the process of construction, 50 tons of excellent steel were consumed. When Vivian heard this huge figure, the sisters were smacking their tongue, because according to the market price, the total value of this batch of steel was more than 400 jinnals.

According to Vivian, the building also used more than 60 tons of cement, although with the increase of production and the improvement of technology, the market price of cement has now dropped to 8 copper nals per kilogram, and the value of this batch of cement also has 50 gold nals.

In addition to other materials, labor and machinery costs, the total cost of this high-rise building is as high as 600 jinnals, which is definitely a building piled up with money.

Tut Tut, your Lord is really rich.

This strange way of building It''s amazing.

Two people saw with their own eyes that the workers with yellow helmets spliced together the framework made of thick iron bars, no, steel bars, and fixed it, and the frame of the building took shape.

Then a kind of mud called "concrete" is poured into the skeleton. After a day, the concrete is completely set to be harder than stone. Then the workers start pouring the second layer.

In the same way, five days later, the building was completed.

This way of building completely subverts the inherent ideas of Aisha and Rachel. They can build houses in this way.

Vivian said that this is the "reinforced concrete building" invented by the Lord. Even the most violent wind and the strongest earthquake can not shake this kind of building which is harder than real rock.

Vivian said that the cement used in the building is the second generation of cement, and the Lord named it quick drying cement.

As the name suggests, it solidifies surprisingly fast. After the first generation of cement hardens, it still needs to be maintained for a week, but the quick drying cement does not need to be maintained. After it completely sets, its hardness reaches the strongest state.

The reason why the performance of quick drying cement is so amazing is that the shell powder of "doom Oyster" is added into it. Because the shell powder contains an isotope of calcium, it greatly speeds up the solidification speed of cement.

Aisha sisters don''t know what "isotope" is, and they don''t know why cement solidifies. Many of the terms Vivian said also make them confused. But this doesn''t prevent them from understanding how great the meaning of cement is.

There is no doubt that this is a revolutionary building material. Once it is popularized, it will completely change the way people build houses.

Vivian also said that the Lord plans to paste a layer of external wall bricks on the outer surface of the building. By then, the building will become very beautiful and will no longer be the ugly appearance of tubulaji.

Vivian also said that the Lord intends to extend reinforced concrete buildings to the whole territory in the future, when all civilians can live in such houses, even in another 50 years, there is no need to worry about the houses being damaged by the storm.When introducing the territory, Vivian mentioned the Lord in five of every ten sentences, and her face was full of pride, which made the two sisters deeply realize how great the influence of the Lord on the tide islands was.

Just what they have seen and heard in the past three or four days, they begin to agree with a view from the heart: Lord, you are the greatest wise man in history.

On the night of the fifth day when they set foot on Odin Island, when the two sisters and the LORD were in trouble, they learned from the Lord''s large population that a new type of machine was about to be tested in public.

The Lord also stressed that this is an extremely important equipment for the shipbuilding industry. With it, all metal ships will become a reality.

Even if she was lying naked under the Lord, facing some indescribable shock, this sentence also made Aisha''s face surprised.

Oh, my God. All metal ships?

How can a huge metal lump float on the sea?

Won''t it sink?

If the person who said this was not the great Lord, Elsa would laugh at him.

After entering "sage time", Lord patiently explained a lot about buoyancy, drew diagrams and wrote mathematical formulas, trying to make the two sisters understand the principle, but it only made them more confused.

What is "the principle of buoyancy is the pressure difference between the upper and lower surfaces of an object"?

"The gravity of an object in a liquid is equal to the buoyancy of the object" is another Magic Horse?

And "liquid can produce more buoyancy than its own gravity." who can tell me what it means?

Are we really speaking the same language as the Lord?

Why is it that we can understand every word the Lord tells us, but we can''t even understand it?

More than ten minutes later, Aisha and Rachel, who are already completely dizzy, completely give up their futile efforts. They look at each other and take the initiative to set off a new "war".

Aisha uses her red lips to block the Lord''s mouth, while Rachel clings to the Lord''s back, holds his earlobe, and moves her tongue flexibly.

Now that they are defeated in knowledge, the two sisters plan to "find the field" in their own way.

Well, men want to conquer the world, but women only need to conquer men.

faced as like as two peas in two "blunt" beautiful female students, the professor had been impatient for a long time. If he hadn''t looked at the two faces, he would have been left behind.

At this time, the students who failed to make progress not only did not want to make progress, but also dared to "challenge" their own authority. Renault immediately decided to punish them severely.

In the vibration of the bed full of rhythm, the fierce "war" started.

This is destined to be an endless "war".
