The live broadcast life of Lao Linzi in Northeast China

Chapter 729 I am very interested in trying to make it (for subscription)
At this time, Li Yuan couldn't help but fell into deep thought.

Seeing that Li Yuan was silent, Hu Kai turned around and closed his eyes, and couldn't help muttering, "Hey, it would be easier if I had a lighter at this time!"

Li Yuan's eyes flickered slightly.

lighter? !

Why didn't I think of it myself!

Li Yuan said in surprise: "There is Kaizi!"

On the side, Kaizi, who had just closed his eyes, heard Li Yuan's sudden agitation, and couldn't help being frightened and instantly opened his eyes.

Hu Kai: "What's wrong!? What's the matter!?"

Li Yuan smiled and said: "Huo, I thought of a way to store the fire, just like a lighter, you can light the fire whenever you need it."

Hu Kai's eyes widened, he looked at Li Yuan in disbelief, and then... asked Hu Kai softly, "You... secretly brought a lighter?"

The voice was very low, obviously afraid that other people would hear it.

Li Yuan couldn't help shaking his head and chuckling.

"No, where are you going? It was agreed not to bring any survival tools, let alone a lighter."

Hu Kai breathed a sigh of relief, and continued to ask: "Then what did you just say that can catch fire at any time? What about such high technology?"

Li Yuan: "Of course, and... you must have heard of this thing."

Hu Kai was a little curious: "I've heard of it? What?"

Li Yuandao: "Huozhezi."

Hu Kai: "Huozhezi?! Are you talking about that thing in the TV series that the ancients ignite when they blow it?"

Li Yuan nodded: "That's right, that's it."

Studio.

"If there is such a thing, it will be much more convenient to make fire in the future!"

"Huozhezi? Does this thing really exist?"

"I thought this booklet was fake, but it turned out to be true?"

"Huozhe is indeed a real thing, but I remember that it seems to contain sulfur and nitrate, right? In the wild, where can I find these two things?"

"No, no matter how powerful the anchor is, he can't make sulfur by himself, right?"

"I once heard the teacher talk about the practice of fire dictionaries in the chemistry experiment class, but because it was too difficult...so I gave up."

"And what about this fairy thing? Anchor, are you sure you can make it?"

Li Yuandao: "In ancient times, there were generally two ways to make fire. One is flint and steel, and the other is fire scraps."

"In ancient times, Huozhezi were generally made of cotton, reed tassels, nitrate, sulfur, rosin, camphor and other flammable substances and various spices."

"Nitrate and sulfur are definitely not found in the mountains and forests, but...you can try it and see if you can make fire pockets in other ways."

The principle of Huozhezi is called "resurgence" in physics, which refers to the fact that something that is already burning is in a state of half-burning and half-extinguishing due to lack of oxygen.

At such times, combustion resumes as soon as oxygen is regained, a phenomenon known as re-ignition.

As for Huozhezi, it uses flammable straw paper and artificially adds an outer cylinder outside to create an oxygen-deficient environment for him, turning the open flame into sparks.

When the lid is opened when in use, Mars will regain enough oxygen to start burning.

The principle of Huozhezi is actually not difficult to figure out.Although some materials needed to make Huozie were missing, Li Yuan wanted to challenge it.

Studio.

"It sounds very difficult!"

"But the host, you all know that there is no nitrate and sulfur, can this still be done?"

"This fire book... sounds very high-tech."

"Looking at the host's expression, it seems that he is bound to win the production of fire zhezi?"

"The anchor wants to do too many things, right? Canopy, fish basket, stone axe, pottery pot, and now there is another fire book? Can you finish it?"

Li Yuan said with a smile: "Actually, the addition of nitrate and sulfur to the fire book is only because of the flammable characteristics of these things. It's not that they can't be completely replaced, but it requires some difficulty."

"However... I am very interested in trying to make this thing."

Li Yuan looked eager to try, obviously very interested in the fire book.

Studio.

"Look at the host's expression..."

"It seems that the young man of the Li family likes challenges very much!"

"Sure! You don't understand, this is a man's desire to conquer!"

"The anchor knows a lot, doesn't he? How can Huozhezi know such obscure knowledge so clearly?"

"The Li family's theoretical knowledge is simply invincible!"

"What's the use of theoretical invincibility? The key is whether the anchor can make it?"

"Didn't you listen to the anchor? This thing is very rare. It's normal to make it well, but it's normal if you can't do it."

Li Yuan and Hu Kai got up very early and worked all morning, so they didn't have much time to lie on the wooden bed and fell asleep. When Hu Kai woke up again... beside him The seat is already empty.

……

Studio.

"Why did the anchor wake up after such a long sleep?"

"Didn't you just go to the mountains in the morning? Why did you come back after such a conference?"

"Look at this road, it seems a bit familiar!"

"Hey, this seems to be the mountain forest that I went to in the morning."

"It seems to be true! Then, the bush that Kaizi crushed when he fell is still there!"

"Haha, I will never forget this in my life..."

Li Yuan: "Unexpectedly, I just said that pine oil might be useful in the morning, and I came back to look for it in the afternoon. It seems... the pine resin was discovered in time."

"And I remember... the scented leaves I found last time are also near here."

Li Yuan came out just to find pine resin and fragrant leaves, which can be used to make fire folds.

Thinking that there was a lack of nitrate and sulfuric acid, Li Yuan planned to use the same flammable carbon block as the raw material for making fire books.It's just that if the carbon block becomes powder, it needs a sticky place to gather them together.

At this time, pine resin, which is both viscous and flammable, is an excellent material.

Studio.

"What about the fragrant leaves? What's the use of this thing?"

"Yeah, is it to make Huozhezi smell better?"

"But this is outdoors, so there's no need to pursue fragrance..."

"Replace it with carbon foam? Can this... work?"

"I feel that it sounds a bit dangling, isn't the raw material too bad?"

Li Yuandao: "The reason for putting the fragrant leaves is because the fragrant leaves contain a relatively large amount of oil, which can replace nitrate and other combustibles, so that the fire can burn better."

"But of course, the effect of fragrant leaves is definitely not as good as the flammability of chemicals such as nitrate, but under such circumstances, it can be regarded as a better substitute."

Studio.

"There is actually oil in the fragrant leaves?!"
