The most annoying thing is the current inheritance, and if there are any good things, such as the inheritance of the past, they must always be hidden. Even if the blacksmith strikes iron, he must be a filial apprentice to teach it seriously.

Mr. Han Chongwen helps others print books, and often adds a request for a unique rare book at their home. China has had paper since the Han Dynasty, but many classics are still lost.

Why?

It is caused by this behavior of teaching one hand and hiding one hand.

The most important thing is carpentry and mechanics, these two things, in Lu Feng's view, are the earliest mechanization, if these things can be popularized, then Datang can enter the rapid development period of the industrial revolution earlier.

But if they ask in the name of haha, then it is not necessarily.

Gong Yi Li didn't expect Leng Feng to propose the third thing to them, and he hesitated for a while. To be honest, teaching others the family knowledge of the public loss family really made him feel reluctant.

However, thinking about Confucianism all over the world, it seems that this point is not unacceptable.

Thinking so, Gong Yi Li stretched out his hand, "If the Duke of Guo can do the above two, then the old man guarantees as the head of the Gong Yi family, and the third one can also be done!" ”

Leng Feng also stretched out his hand and high-fived Li San.

Even if two people have reached an agreement, in fact, the real person in power, if the agreement, only needs to be confirmed by both parties, or even no paperwork is required at all.

After three high-fives, Gong Yu Po breathed a sigh of relief

Fortunately, fortunately, Guogong took care of his grandfather, otherwise, he wouldn't know how to talk to his grandfather about the rise and fall of the family.

In this way, it is very good, as long as the public loss family that has entered the WTO and formed a faction, as long as it is not involved in the dispute over power, it will definitely become a family with a long inheritance like the five surnames.

After three high-fives, Gong Yi Li laughed and showed Leng Feng his drawing.

"Guogong, look at it, is the old man's idea close to success? To be honest, as long as the old man can stick to the idea of experimenting with Kong Minglantern, he may be able to find the right idea.

It's a pity that I just didn't stick to it. ”

Leng Feng opened the drawings of Gong Yi Li and looked at it, to be honest, the drawings drawn by Gong Yi Li were already eight points similar to that of a hot air balloon.

But

Leng Feng pointed to the orb above and said, "This is not right, alas! Why do you always think about using papier-mâché? How nice it would be to switch to silk. ”

Gong Yi Li wondered, "Silk? If that thing doesn't work, it catches fire when it sees it, then it's not a flying lantern, it's a fireball. How good the paper is, although it is flammable, but as long as the paste is thick enough, it is estimated that it is no problem to fly once. ”

"But what's the use of such a flying lantern? That's not a one-time consumable. ”

Leng Feng slapped his forehead, "Just use silk, and weave thick kind of silk, in this way, as long as the fire is covered with a layer of asbestos net, there should be no problem." ”

"Asbestos netting?" Gong Yi Li asked suspiciously, "What is that?" ”

Leng Feng didn't know how to explain it, to be honest, he only had the memory of itching and peeling off a few layers of skin after touching it with his arm when he was a child.

This thing is the most common fireproof material, since there is the word asbestos. Then it should be there.

If you're looking for something, there's no better way to do that than by posting a notice on the bulletin board downstairs under heaven. The bulletin board on the upper floor of the world is the place where businessmen pay the most attention. As long as some kind of notice is posted, well-informed businessmen will always have a lot of clues.

For example, asbestos is like this, Leng Feng just asked Lao Yuan to inquire, but the next day a businessman said that his family had this mine, but he just felt that it was useless, and it was just a matter of not doing it all the time.

As long as the hot air balloon experiment can be successful, the asbestos mine will definitely become a big gold mine, and even private mining will be banned. So Lao Yuan directly explained the benefits to the businessman and took the mine.

After Leng Feng asked the miners to prepare comprehensive protection, he sent them to the mine to mine asbestos, and it is estimated that it will not take long to mine it.

Therefore, the focus of hot air balloon research is actually on gasoline blowtorches.

"As long as there is asbestos netting, then the silk is not afraid of the direct baking of the flame, so"

Leng Feng pointed to the lower end of the sphere, "The focus now is on how to make the flame output stable, we have to call this thing, let's call it a gasoline blowtorch, we have to get the gasoline blowtorch out!" ”

Gong Yi Li took the drawing, thought for a while, and then said, "Since your asbestos net is so magical, then, you should concentrate on studying the asbestos net." Leave the matter of gasoline blowtorch to the old man! ”

After speaking, he looked at Leng Feng embarrassedly, "The old man knows that you want to relax at home recently, but the old man really wants to realize his dream."

The old man is eighty-five this year, and he feels that every time he wakes up, he has already earned money. At such an age, he encountered the opportunity to realize his dream, and the old man really didn't want to see the flying lantern taking people to the sky, so he died, in that way, the old man would really die without turning a blind eye. ”

After speaking, Gong Yi Li bowed seriously to Leng Feng.

Gong Lose Li Du is like this, Gong Lose Po and Gong Lose Hui simply fall to their knees.

Leng Feng hurriedly asked Li Tai to pull the two kneeling down, and personally went to help Gong Li.

At the age of Gong Yi, it can indeed be said that he is about to die. Such an old man, although stubborn, although Leng Feng and him have just met, but those who should be helped, they must also be helped.

This is the respect that an elder character should have.

"Mr. Gongyi, I should help you, the juniors will definitely help, you are like this, aren't you shouting at the juniors to lose their lives!"

Gong Yi Li straightened his waist and said with a smile, "Since you are willing to help, then the old man will strive to live for a few more years, when will the introduction see the success of the flying lantern, and when, the old man will be able to die without worry." ”

Eighty-five years old, a person at this age has seen through the world and experienced enough, so he doesn't attach so much importance to life and death. Perhaps the "old death" that young people talk about is just a simple relief in his eyes.

Gong Yi Po walked over and grabbed Gong Yi Li's hand, "Grandpa, what are you talking about, the grandson is still waiting for you to hold the little great-grandson, besides, isn't there another plane?" What is the flying lantern, the free flight of the airplane is what you should pursue. ”

Although he has a prejudice against his grandfather, when it comes to life and death, it seems very filial to lose the public.

Young people are like this, when they are young, they hate them for not dying, and when the elders are really old, they will be reluctant, and it will be the same to everyone.
