After returning from Jia Liu, Gao Fei did not rush into the house, but went to the house first and hid the fifteen big coins in the firewood.

Then he sat quietly on the pyre, looking thoughtful.

If he really wants to make a fortune by selling refined salt, then he must be able to make it from it, and only then can he have a steady stream of money.

As soon as he thought of this, Gao Fei picked up the brine salts he had poured out during the day, and he was going to do an experiment to purify these salts and turn them into refined salts, and at the same time wanted to see what was the difference between the refined salt he refined and the salt he brought.

So, Gao Fei sneaked into the house quietly, and when he saw that Gao Yunniang was still asleep, he was cautious, for fear of waking her up by touching something. He took out the first-aid kit from his backpack, opened it, took out a roll of medical gauze from it, and then quietly returned to the room.

Gao Fei first grinded the lumpy brine salt into powder, then poured the powder into a pottery bowl that had been prepared, and then added water to let it dissolve completely, the water turned muddy, and some impurities were clearly visible.

After that, Gao Fei took out the gauze, cut off a small piece, tied the four corners with a thin thread, fixed it on top of another pottery bowl, and then slowly poured the dissolved water on the gauze, the gauze filtered out some impurities in the water, and the salt water sank into the second pottery bowl.

Gao Fei used the same method to place the third and fourth bowls, cut five pieces of gauze, first superimposed two pieces of gauze on top of each other, fixed them on top of the third bowl with a thin thread, and then superimposed the remaining three pieces of gauze together, still fixed on top of the fourth bowl with a thin thread.

At this time, Gao Fei slowly poured the salt water filtered into the second pottery bowl into the third pottery bowl, and filtered out a layer of fine impurities on the gauze. Immediately afterward, Goofy poured the salt water filtered into the third bowl into the fourth bowl, and the three layers of superimposed gauze were filtered again.

Finally, Goofy poured the salt water filtered into the fourth bowl into the large iron pot on the stovetop, and then lit a fire under the stove, and kept filling it with firewood, as the fire increased, the temperature of the iron pot became higher and higher, and it didn't take long for the water on the iron pot to boil, and the water became less and less, but the bottom of the pot had a layer of small, white crystals.

Gao Fei took out all these white crystals and put them in a pottery bowl, and compared them with the modern table salt he had brought, but if you didn't look closely, I was afraid that it would be difficult to notice the difference.

After the experiment, Gao Fei's confidence was much more sufficient, at least he knew that such a technique would never starve to death in ancient times. He cleaned up the room again, washed the gauze with clean water, and then went back to sleep satisfied.

The next day, Goofy dressed, got up, brushed his teeth, washed his face, ate as usual, and spent the rest of the time sitting by the charcoal fire in a daze.

said that he was in a daze, but in fact, his mind was full of thoughts. The most worthy of his attention now is the fact that Jia Liu took refined salt to the county seat.

As Gao Fei expected, just after breakfast today, Jia Liu borrowed a donkey cart from Lao Wang next door, drove the donkey, and went to the direction of the county seat.

As for what Jia Liu was doing in the county seat, Gao Fei knew best in his heart, he must be going to resell the pound of refined salt he sold to him last night. Perhaps, even the salt borrowed by Mrs. Jia Liuniang yesterday was resold.

If Jia Liu's resale of refined salt is successful this time, Gao Fei will continue to the next step and sell the refined salt he refined from the brine salt last night to Jia Liu again, so as to open up the sales of refined salt with the help of Jia Liu's hand.

The thought that there will be a steady stream of money in the future makes Goofy's heart feel happy, and he laughs from time to time.

"Bang! Boom! Boom! ”

A dull loud noise kept coming in from outside the house, and Gao Fei couldn't concentrate on thinking about things, so he got up and walked to the door of the house, lifted the curtains, and saw Gao Yunniang picking up a huge axe and slashing at the wooden stake standing on the ground.

"Bang!"

There was another dull loud noise, and the wooden stake on the ground was instantly split in half, and then Gao Yunniang picked up a wooden stake and placed it straight on the ground, picked up the axe and slashed downward.

Gao Fei's face was full of surprise, he never thought that looking at Gao Yunniang, who was thin and small, he could have so much strength.

With a "bang" sound, Gao Yunniang split another wooden stake, at this time she had already split five or six wooden stakes in a row, and the high-intensity physical labor made her a little unbearable. She put the axe on the ground and was about to sit on a stake to rest for a while, but she didn't want to catch a glimpse of Gao Fei standing at the door of the house, and hurriedly asked: "Yu'er, it's cold outside, go back to the fire quickly, so as not to catch a cold." ”

Gao Fei shook his head and said: "I'm alone in the house, it's boring, and if I always stay in the greenhouse, my body will lack the resistance it should have, so it's better to adapt to the outside environment, and if I get used to it, I will never feel cold again." ”

After listening to Gao Fei's words, Gao Yunniang thought about it carefully, and it seemed that this was the reason he said. However, when these words came out of the mouth of a five-year-old child, people always felt a little strange when they heard it.

Gao Fei walked towards Gao Yunniang and said, "Besides, it's such a cold day, it's okay for you to stand outside, and I'm definitely fine......"

Before Gao Fei finished speaking, Gao Yunniang interrupted Gao Fei's words: "How can this be the same, I am an adult, you are still just a child, you are still young, children and adults are incomparable......"

Gao Fei didn't want to say more, he just walked to Gao Yunniang's side and said with a smile: "Whether it's an adult or a child, I don't want to stay in the house anyway, although it's cold outside, as long as you move more, it won't freeze." ”

As soon as the words fell, Gao Fei bent down to pick up the axe on the ground, and said to Gao Yunniang: "I'll help you chop wood!" ”

As soon as the axe was in his hands, Goofy felt heavy, and he barely lifted it above his head, and his arms were already shaking. Seeing this, Gao Yunniang hurriedly snatched the axe from Gao Fei's hand.

"Your kindness, my mother already knows, but this axe is not something you can take, if you hurt yourself, the consequences will be serious!" Gao Yunniang is a serious way.

Goofy shrugged his shoulders and pouted, "I'm just trying to help......"

"Mother doesn't need your help with anything, as long as you have this heart, it's enough, and my mother can handle these things." Gao Yunniang said while smiling at Gao Fei, although her expression looked very relaxed, but Gao Fei understood very well that chopping wood was a very heavy job.

"After I make a lot of money, you don't have to do anything anymore, I have to find a few maids to serve by your side, so that you can enjoy a lifetime of happiness." High Flying Road.

After Gao Yunniang heard this, she didn't mention how relieved she was, her eyes were already moist, and she couldn't help laughing, so she hugged Gao Fei tightly in her arms and said slowly: "Son, with your heart, my mother will be satisfied." ”

In the following time, Gao Yunniang chopped firewood, and Gao Fei helped carry firewood in the court's room, and placed it neatly. In addition, Gao Fei also helped Gao Yunniang make a fire, boil water, and cook. The two of them are very happy to cooperate, although it is cold, but the mother and son have never felt a trace of cold, on the contrary, their hearts are warm.

In the evening, Gao Fei saw Jia Liu coming back leisurely in the donkey cart in his yard, Jia Liu first returned the donkey cart to the old king next door, and then went home happily.

Seeing Jia Liu's appearance like this, Gao Fei had already guessed that Jia Liu must have sold those refined salt for a good price.

In this way, Gao Fei had to go to Jia Liu again tonight and sell the refined salt he refined last night to Jia Liu again.

When night fell, Gao Fei went to bed early after dinner, and Gao Yunniang also went to bed about ten minutes later.

Gao Fei waited until Gao Yunniang fell asleep, then he dared to sneak out, and after a while, he came to Jia Liu's door.

Goofy raised his hand and slapped the door three times, making a "bang, bang, bang" sound, although his knock on the door was not loud, but in such a quiet night, it was still extraordinarily clear.

"Who?"

The lights were lit up in Jia Liu's room, and Jia Liu walked out of the house wearing a thick coat, still standing at the door looking out, and asked cautiously, "Who is outside?" ”

"Uncle Liu, it's me!" Goofy replied.

When Jia Liuyi heard this voice, he came to his senses, hurriedly walked towards the gate of the courtyard, hurriedly opened the courtyard door, and sure enough, he saw Gao Fei standing outside. He cleared his throat first, and then asked unhurriedly, "Yu'er, is your mother's illness cured?" ”

"Thanks to Uncle Liu's last night, my mother's illness has improved a lot, and I came to thank Uncle Liu's ......"

"You kid, what are you thanking for, they're all neighbors, and it's right to help each other. That one...... Yu'er, do you still have the refined salt you sold me yesterday? ”

"Yes, yes, but there is not much left, probably only the last catty left."

Jia Liu's eyes lit up, and he hurriedly said, "One catty is fine, then can you still sell me those refined salts?" ”

Gao Fei deliberately showed some hesitation, and after thinking about it for a while, he said: "Uncle Liu, I can sell you this last catty of refined salt, but I don't need money this time, can you help me buy a few catties of brine salt?" ”

"Of course you can, not to mention only a few catties of brine salt, even if it is dozens of catties, hundreds of catties is not a problem, anyway, this thing can be bought everywhere."

At this time, Gao Fei took out a pottery bowl from his arms, and the pottery bowl still contained a bowl full of refined salt, which was the refined salt he had refined last night.

Gao Fei put these refined salts in front of Jia Liu, but seeing that Jia Liu's face showed a greedy expression, the corners of his mouth rose, and he couldn't help laughing......
