Lao Feng took the task, took the drawings, and went out.

Zong Shu drew another picture, this is the city tower and corner tower of the Bianliang city wall.

Zong Shu pointed to the city gate building and said: "This building is very good-looking, but it is not very useful, dozens of stone throwers will be smashed within an hour." ”

The city gate tower of Bianliang is a three-storey triple eaves rest mountain type, four corners of the cornice, brick and wood structure, elegant, exquisite, beautiful, and the attic of ordinary large families is not much different.

Zong Shu even felt that the Daxiong Treasure Hall of this city gate building was moved over as it was.

"If you look at the castle tower and the chest photo just now, if the castle tower is built into the shape of the chest photo, and the stone is thrown at it, will it slip to the side?"

Zong Shu inspired.

Lin Lingsu, Li Shaoyan, and Cao Zongshen's eyes lit up, yes, if this chest photo is enlarged into a city tower, and the stones of the stone thrower fly over, won't it fly diagonally?

Looking at the current city tower and corner tower, the stone flew over, and it really hit it!

Zong Shu took out another raw egg from his pocket, which was a teaching aid for his on-site teaching today.

"You three, who can crush this egg?" Zong Shu asked.

Lin Lingsu, Cao Zongshen, and Li Shaoyan took turns to come up and hold it hard, the eggs were so good that they didn't break.

It's a strange thing, just such an egg, it just can't be broken.

The shell of the egg is so thin, but it is not easy to crush, which has attracted the attention of scientists, so the imitation egg architecture was born.

From egg-like architecture, bionic architecture was born.

British firefighters threw ten eggs into the grass from a fire ladder 21 meters above the ground in order to test the force on the eggs, but only three of them broke.

At the CCTV Spring Festival Gala one year, a girl performed stepping on eggs, carrying a bucket of water in each hand, and stepping on four eggs with both feet, and the eggs were also safe and sound.

Of course, it's another thing to break the egg, it's a problem with the eggshell itself, which in turn involves the relationship between pressure and pressure.

"The castle tower and corner tower are made eggshell-shaped?" Li Shaoyan began to think: "How to maintain stability? ”

"As long as half of the egg is put on," Zong Shu said, "this is called a dome building." ”

Zong Shu gave the example of the arch bridge, the reason why the arch bridge will not collapse for thousands of years is because the mechanical structure of the arch is reasonable.

The bricks are thick at the top and thin at the bottom, stuck one by one.

In fact, the corner tower can also be built with bricks in the way of arch bridges, and such a dome is not easy to be smashed by a stone thrower.

Lin Lingsu also proposed that the soil could be built below in advance, and there were three layers inside and outside, and the middle of each layer could be filled with sawdust.

Zong Shu immediately affirmed Lin Lingsu's creativity, which was equivalent to putting three domes together. Even if the upper layer is really smashed with stones, there are still two floors waiting below.

There is wood chips in the middle of each layer, and the destructive force from the top layer will also be canceled out in the wood chip layer.

The three domes didn't really cost much, it cost only bricks and manpower.

Lin Lingsu was very pleased with Zong Shu's praise, and he had been following Zong Shu all along, listening to him talk about all kinds of fresh ideas and theories, remembering and understanding with his heart.

I found that Zong Shu is always good at finding ideas from everything and finding ideas to make money.

Moreover, seemingly unrelated things, Zong Shu can often connect well.

For example, a woman's chest photo, ordinary eggs, and arched bridges that can be seen everywhere are actually the same as the defense of the city gate tower and the corner tower.

Not only Lin Lingsu understood, but Li Shaoyan and Cao Zongshen also understood.

"Lingsu, is the glass cover made now?" Zong Shu asked.

"The Academy of Sciences has made samples, and the kerosene and paraffin you mentioned have also been successfully extracted." Lin Lingsu replied.

Zong Shu nodded, Zong Shu didn't care about the extraction of kerosene at all.

It is easy to extract iodine, produce penicillin, and extract kerosene from petroleum.

Kerosene is refined from petroleum by fractional distillation.

Kerosene has a relatively low boiling point and is the first to be fractionated from petroleum.

The oil is then distilled, and the temperature is further raised, and the paraffin wax is refined.

If Lin Lingsu hadn't been extracted yet, Zong Shu would have doubted their abilities.

The oil that Qin Dali transported from Puzhou Village was placed at the base in Mixian County and handed over to Lin Lingsu for disposal.

Now that kerosene and paraffin are produced, which are only part of the use of petroleum, it is time to establish the Dasong Chemical Company.

"Zongshen, I'll give you a task, go to Wazi and various shops to spread the news, just say that my Zong's group is going to make candles, and if you want to cooperate with us, we welcome it." Zong Shu said.

Cao Zongshen did a lot of this kind of thing, and once spread the news that Cai Jing and Tong Guan were going to harm Zong Shu.

Originally, Cai Xiu wanted to attack Zong Shu, but when he heard these news, he didn't dare to move.

The young master asked him to spread the news again, who is he guarding against this time?

I don't want to do it so much, the things that the young master explains, don't talk about the conditions, just do it well.

Li Shaoyan immediately said that he wanted to invest in Dasong Chemical Company.

Facts have proved that as long as you follow Zong Shugan, you are guaranteed to make a lot of money.

No matter whose money it is, Zong Shu will accept it all, although he is not short of silver now.

Zong Shu said that no matter who invests money, they are all shareholders of Dasong Chemical Company.

Anyway, there is no policy that prohibits non-governmental fund-raising, and only by pooling everyone's money can we do great things.

"Lingsu, you are looking for a mine called bauxite in a place called Xiangshuitang in Mi County." Zong Shu confessed: "With this, we can make better porcelain. ”

Bauxite, as the name suggests, is an earth-like mineral that contains aluminum. White or off-white, brownish yellow or light red if iron-present.

Lin Lingsu took out the lead and wrote down the mineral characteristics, and when he went back, he arranged for someone to look for it.

……

Zong Shu no longer slept in the morning, and pulled Li Shaoyan and Cao Zongshen to exercise together, mainly running five kilometers and practicing push-ups.

Li Shaoyan was also a lazy person in the past, and the reason why he practiced with him was mainly because he felt that he was about to open a green building, and his body had to be trained well.

The reason why Zong Shu exercised was mainly stimulated by Wei Gonggong Wei Yegong.

I almost went to Master Li that time, and this old eunuch with hemp skin ruined his good deeds.

A few days ago, I was teased by the old woman with a hemp skin under Ruyan.

Both of them are martial arts people.

Zong Shu is also older, and it is too late to practice martial arts, but there is no harm in practicing physical strength and endurance.

If you meet someone who is a master and sees that your bones are strange and you want to teach him, but your body has been hollowed out, wouldn't you miss the opportunity?

As soon as Zong Shu arrived home after running, he saw Zuo Xiaomu waiting at the door, saying that His Royal Highness the Crown Prince had something urgent to find him, and asked him to rush to the East Palace as quickly as possible.

What's so urgent? It's sweaty, and I haven't washed it yet.

Hurriedly entered the palace and found that Empress Liu, Zhuzhu and His Royal Highness the Crown Prince were all in the East Palace.

Zong Shu was about to give a gift to Empress Liu, and Zhao Huan couldn't help but be excited: "Grandmaster, exact news, Jin Guo, after Yan Agu beating, is dead!" ”
