"The solution to the problem of weathering is actually very simple." Li Fei said with a smile:

"Weathering, as the name suggests, is to be blown by the wind for a long time, so it melts. Of course, it's certainly not that simple. The reason why coal is weathered is that the overall structure is destroyed and becomes brittle after being exposed to the wind and sun for a long time, and then it is broken.

To solve this problem, all you need to do is keep the coal dry! ”

The shopkeeper Deng has a difficult face:

"This coal pile is so high, it is too expensive to build a large warehouse and put it in......"

"You don't need to build a house." Li Fei shook his head and said, "Two ways." One is to use grass to cover the coal pile tightly, so as to prevent wind, sun and rain, which will greatly reduce the degree of weathering. ”

Looking at the dozens of coal piles that are several feet high, this is also a big project.

How much grass is needed!

"The second option is relatively simple, it just requires some labor." Li Fei pointed to the ground and said, "You only need to dig a big pit in the ground, bury the newly pulled coal in it, and cover it with soil." Anyway, the coal was originally dug out of the ground, and there is no such thing as deterioration. Just dig it out when you sell it! ”

Li Fei remembers that in his original era, there were coal sellers in the north, that is, in the summer, when the price of coal was low, they went to the coal mine to buy coal, dug a big pit in the Gobi Desert on the side of the road, poured the coal into it, covered it with soil, set a gentle slope at the opening, and sold it in bulk when the price of coal was high in winter.

There is soil cover, as long as someone looks at the fire, basically there will be no problems.

When the shopkeeper Deng heard it, this method was feasible!

Li Fei said: "You only need to set up an exit and dig a gentle slope, and then you can enter and exit the carriage here to load coal, which will not affect the loading and unloading, and can also avoid weathering." ”

"Good!" After listening to this, Shopkeeper Deng understood what Li Fei meant, which is completely feasible!

Although it will cost some manpower, it can avoid great losses, and thirty percent of coal, that is not a decimal!

"I'm in charge, the coal dust in this charcoal field belongs to Li Gongzi!" Although Shopkeeper Deng hasn't verified it yet, he is sure that Li Fei's method must be fine!

Li Fei smiled and didn't speak again.

Qu Tuquan was a little surprised: Li Fei seems to be able to do surprising and unexpected things wherever he goes!

When the shopkeeper Deng went to find someone to tell him about this, he expressed his admiration to Li Fei, and Li Fei said modestly:

"Ji!"

In fact, my heart is also very beautiful, I haven't gotten high-quality wool for several days, today's handful, it's really cool!

After a while, the shopkeeper Deng came over and said to Li Fei: "For the first batch, I will let the carts in our charcoal shop give Li Gongzi ten carts of coal to you, and Li Gongzi will need to transport the rest by himself!" ”

This condition is already very generous for Li Fei. He nodded and said no more.

He can afford this offer!

told the shopkeeper Deng where the coal dust needed to be sent, and introduced Qu Tufeiying and Chen Hu, explaining that they would come over to pull the coal dust in the future, and Li Fei left with people.

There's more important things to do!

This time, it was Qu Tu Feiying who led the way and took everyone to the Zhuangzi of Qu Tuquan's house.

Zhuangzi is not far from Chang'an City, but it is in the east of the city, so it needs to be detoured.

When he was about to arrive at Zhuangzi, Li Fei suddenly stopped, he saw the soil on the side of the road, was overjoyed, and asked Qu Tufeiying directly:

"Steward Qu Tu, how far is this from your Zhuangzi?"

"It's less than a mile away." Qu Tufeiying didn't know why Li Fei was asking this, but he still answered honestly.

He could see that Qu Tuquan's casual attitude towards Li Fei had never seen this kind of attitude in people who usually claimed to be friends of Qu Tu's second son!

This person must be the second son's best friend!

Li Fei asked again:

"Then here, is it your Zhuangzi's land?"

"Yes. From here to Zhuangzi, it is the land of our grandfather Qu Tu. ”

"Great!" Li Fei laughed, "This time, the raw material problem is all solved!" ”

Qu Tuquan asked suspiciously:

"Feige'er, is it ...... This loess...... Useful? ”

Li Fei said with a smile: "Naturally useful, useful!" Mixing this loess into coal powder has many benefits! ”

Qu Tufeiying couldn't help but say: "Isn't that shoddy, the work of profiteers?" ”

Although Chen Hu didn't know why Li Fei did this, he subconsciously argued for Li Fei:

"Fei Ge'er can't be a profiteer! He is in Yongning Fang, but he has exposed the affairs of profiteers! ”

Qu Tufeiying glanced at him contemptuously and did not speak.

Qu Tuquan said with a smile:

"Brother Fei'er, you better tell the reason! I'm also sure that you're not a profiteer, but the reason is not clear, my family's steward is a stubborn character, I'm afraid I won't do it well! ”

Li Fei grabbed a handful of half-dried red clay and pinched it in his hand, felt the stickiness, and said with a smile:

"If you don't ask, I'll make it clear. We want to do this business for a long time, and naturally we can't do what the profiteers do. However, some things are not as simple as you think! ”

He threw the red clay away, clapped his hands, and continued:

"For example, this red soil, put here, is extremely useless, and the crops are not good to grow, but mixing it into the coal powder, and then beating it into honeycomb coal, can make the honeycomb coal stronger, not easy to break, easy to transport, and easy to dispose of after burning."

Qu Tufeiying was still a little unconvinced and said:

"Isn't the coal dust directly beaten into a briquette? Why bother? ”

Li Fei knew that if he didn't explain it clearly, he was afraid that this stubborn guy wouldn't do a good job in the future, so he said:

"Did you just hear what the old man said? In fact, the honeycomb coal we make is nothing new. Some people use briquettes to use them, but as you have heard, the business of briquettes is not very big, compared to lump coal, it is too little! Do you know why? ”

Qu Tu Feiying shook his head.

He really didn't know.

"Because briquettes are fragile." In Li Fei's words, "The minced coal is kneaded into a cake with water, and it is dried to become a briquette." It seems to be no different from a lump of coal, but it will be broken at a slight touch, and it is difficult to burn when the coal is broken, and there is a lot of smoke, even ordinary people do not want to use it.

However, by adding red clay and making honeycomb coal, the shortcomings of this briquette are gone. And we make it into a honeycomb shape, it is very easy to burn, the heat is dissipated quickly, and the burn is sufficient, which is naturally stronger than the briquette - and most importantly, ours is cheap! ”

There is no business, only labor costs are required, and it is naturally cheaper!

Li Fei explained these and said no more.

There are some things that are useless to talk about, and only in the face of the facts will these stubborn people stop talking and no longer doubt.

But there are also benefits to these stubborn people, once their perceptions are reversed, then they will become loyal fans, and it will be easy and difficult to change!
