Datang Longya

Chapter 500
What I hate the most is that the current family status has been passed on. If there are any good things, such as the past inheritance, they always have to be hidden.Even if a blacksmith forges iron, he must be a filial apprentice to teach seriously.

Mr. Han Chongwen helped others to print books, and he often added a request for a rare copy in their home.China has had paper since the Han Dynasty, but many classics are still lost.

why?
It is this kind of behavior of teaching one hand and hiding another hand.

The family education of the public losers is mainly carpentry and machine skills. These two, in Lu Feng's view, are the earliest mechanization. If these things can be popularized, then Datang can enter the rapid development of the industrial revolution earlier. period.

But if they teach knowledge with the name of haha, then not necessarily.

Gongshu Li didn't expect Leng Feng to bring up the third matter to them, so he hesitated for a while.To be honest, it really made him feel reluctant to teach others the family knowledge of the Gongshu family.

However, thinking about Confucianism, which is full of peaches and plums, it seems that this point is not unacceptable.

Thinking of this, Gongshu Li stretched out his hand: "If Duke Xi can do the above two things, then, as the head of the Gongshu family, I guarantee that the third thing can also be done!"

Leng Feng also stretched out his hand, and gave Gongshu Li San a high five.

This is considered to be an agreement between two people. In fact, the real person in power only needs confirmation from both parties if the agreement is made, and there is no need for document constraints at all.

After three high-fives, Gong Shupo heaved a sigh of relief.
It's a good thing, it's a good thing Duke Xing got his grandfather settled, otherwise, he didn'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 Gongshu family that has joined the world and formed a faction does not get involved in power disputes, it will definitely become a family with a long history like the five surnames.

After three high-fives, Gongshu Li laughed, and showed Leng Feng his blueprint.

"Guo Gong, look, is the old man's idea close to success? To be honest, as long as the old man can persevere in the idea of ​​experimenting with Kongming lanterns, he may actually find the right idea.

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

Leng Feng opened Gongshuli's drawing and looked at it. To be honest, the drawing drawn by Gongshuli was already [-]% similar to a hot air balloon.

But
Leng Feng pointed to the sphere above and said, "This is wrong, alas! Why do you always think of using paper? It would be nice to use silk instead."

Gong Shuli asked suspiciously: "Silk? That thing can't be made, it catches fire when it sees fire, then it's not a flying lantern, it's a fireball. How good is paper, although it's just as flammable, but as long as the paste is thick enough, it probably won't fly once." questionable."

"But what's the use of such a flying lantern? Isn't that a one-time consumable?"

Leng Feng patted his forehead: "Just use silk, or weave thick silk. In this case, as long as a layer of asbestos net is placed on the fire-breathing area, there should be no problem."

"Asbestos net?" Gong Shuli asked suspiciously, "What is that?"

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

This thing is the most common fireproof material, since there is the term asbestos mine.Then it should also exist.

If you want to find something, there is no better way than posting a notice on the Tianxialou bulletin board.The bulletin board of Tianxia Building is the place that businessmen pay most attention to.As long as some kind of notice is posted, well-traveled and well-informed businessmen can always provide a lot of clues.

For example, asbestos is like this. Leng Feng just asked the old man to inquire about it, but the next day a businessman said that his family had this mine, but he thought it was useless and never took it seriously.

What a waste, as long as the hot air balloon can be successfully tested, the asbestos mine will become a big gold mine, and private mining will even be prohibited.So Lao Yuan directly explained his interests to the businessman and won the mine.

Leng Feng asked the miners to prepare comprehensive protection before sending them to the mine to mine asbestos. It is estimated that it will not take long to mine it.

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

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

Leng Feng pointed his finger at the lower end of the sphere: "The important thing now is how to make the flame output stably. We have to call this thing a gasoline blowtorch. We have to get the gasoline blowtorch out!"

Gong Shuli took the blueprint, thought for a while and said, "Since your asbestos net is so miraculous, then you should concentrate on studying the asbestos net. Leave the gasoline blowtorch to the old man!"

After finishing speaking, he looked at Leng Feng embarrassedly: "I know that you want to relax at home recently, but I really want to realize my dream.

The old man is already eighty-five this year, and it feels like he has earned money every day he wakes up.It is only at this age that I meet the opportunity to realize my dream. I really don’t want to die like this without seeing the flying lantern take people to the sky. In that case, I will really die with regret. "

After finishing speaking, Gong Shuli bowed seriously to Leng Feng.

Gong Shuli was like this, Gong Shupo and Gong Shuhui simply fell to their knees.

Leng Feng hurriedly asked Li Tai to pull the two kneeling down, and he went to help Gongshu Li himself.

At Gongshu Li's age, it can indeed be said that he is about to die.Although such an old man is stubborn, even though Leng Feng and him have just met, he must help what should be done,
This is the respect an elder should have.

"Mr. Gongshu, if I should help you, this junior will definitely help. If you are like this, don't you say that the junior will lose your life!"

Only then did Gongshu Li straighten his waist, and said with a smile: "Since you are willing to help, then I will try to live a few more years. When I see the success of the flying sky lantern, I can die without any worries."

85 years old, people at this age have already seen all kinds of things in the world, experienced enough, and don't value life and death so much.Perhaps the "death of old age" that young people talk about, in his eyes, is just a simple relief.

Gong Shupo came over and grabbed Gongshu Li's hand: "Grandpa, what are you talking about? Your grandson is still waiting for you to hold your great-grandson. Besides, isn't there an airplane? What are flying lanterns? Flying freely is what you should pursue."

Although he is very prejudiced against his grandfather, when it comes to life and death, Gong Shupo is very filial.

Young people are like this. When they were young, they hated him for not dying. When the elders really reach their age, they will be reluctant to part with it. It is the same for everyone.

　I, decided to play a monthly pass!
