Time passed unhurriedly, and I spent a long time at home. Finally one day, the sky was completely clear and the rainbow was revealed, and Bai Yun looked at the rainbow and pointed excitedly, Sister The rainy season has passed, and you look at the rainbow is a sign of the end.

Liu Qingxun turned his head to look at the past, a rainbow appeared in the refreshing sky, red, orange, yellow, green, blue, and purple intertwined, and suddenly thought of a long bridge lying on the waves, clouds and dragons. Liu Qingxun looked at the rainbow, and said with a smile on the corner of his mouth: It's really beautiful, gorgeous and colorful.

Bai Yun ran over and hugged Liu Qingxun and said: The rainy season is over, can my sister tell us how to make salt more exquisite?

Liu Qingxun said: Of course, there is no problem with this, if you want to start construction today, start construction today!

Immediately, Liu Qingxun called out Bai Yue, who was eating in the house, and Bai Yue hurriedly said with his breakfast stuffed in his mouth: Wait, wait, wait until I'm done, don't listen to Bai Yun's kid.

Bai Yun looked at the words in his brother's mouth as if he was angry, and immediately hugged his sister's leg and faced her, and said with stars in his eyes: Sister is not in a hurry, let the gluttonous eat it first!

Liu Qingxun pinched Bai Yun's little face and said: Little thing, now it's getting more and more slippery, you even dare to joke with your brother, but my sister supports you.

Liu Qingxun hugged the child on his lap and said: Bai Yun, do you want to know how to make the salt more refined?

Bai Yun nodded heavily and said, "Of course I want to know!" My sister told Bai Yun that Bai Yun must be doing better than her brother. As Bai Yun nodded, the cute baby fat and flesh on his face were very cute, Liu Qingxun also pinched the little milk fat on Bai Yun's face, Bai Yun buried his head in Liu Qingxun's neck and said: If you can't pinch too much, your face will be red.

Liu Qingxun patted Bai Yun's ass and said: Stinky little ghost, I know. Then he asked Bai Yun: Now please ask my good student Bai Yun to tell me what kind of impurities are in the seawater?

Bai Yun tilted his head and said: I don't know what impurities are, is it a bad thing? After that, he smiled embarrassedly.

Liu Qingxun smiled and said: Baiyun is really smart, it is indeed a bad thing, there are several important ones that are sulfate ions and magnesium ions, we just need to remove these ions.

Bai Yun innocently asked: Then why didn't I see it? Are they tiny, tiny, smaller than ants?

Liu Qingxun said: It is indeed smaller than ants, ants should be regarded as giants for them, they are some invisible ions, they need a microscope to see, it is a pity that there is no microscope in the beast world!

Liu Qingxun also thought of Leeuwenhoek's stalk, so he told Bai Yun about it, and Bai Yun couldn't stand up straight with a smile. Bai Yun also said that he wanted to use the Leeuwenhoek meme to show off to his friends that he was well-informed.

Looking at Bai Yun's stinky fart, Liu Qingxun couldn't help but chuckle and said: When the time comes, you will be too show-off and beaten by someone, don't cry your brother's nose!

Bai Yun looked shocked and said: How could I cry with my brother? Sister, hurry up, how do you get rid of those bad ions?

Liu Qingxun said that only a small amount of fresh water needs to be added to the salt we made before, and the saturated salt water can be precipitated and filtered!

"That's true," the man arrives before he hears. Bai Yue hugged Bai Yun in his arms and said: This little fat man has been eating more and more recently, and he is also grateful to Qingxun for his good temper, and he is willing to hold him.

Liu Qingxun raised his eyebrows and said: Bai Yun is so cute, if he becomes a little tiger, he may be lighter. But this kid doesn't seem to have turned into a tiger much lately? Hey, I haven't touched Maomao for a long time, and I don't know if Baiyun's Maomao is still as warm as before?

Bai Yun thought of being scolded by his brother and sister before. Every night, I had to run to the river to wash my hair, and I couldn't help but be very frightened: not soft and not soft and white clouds' hair is not soft. My brother's softness, my brother's hair is comfortable, and it's beautiful and oily.

Liu Qingxun looked at Bai Yun's behavior of selling his brother, laughed very rampantly and said: Okay, Bai Yue has also come out, then let's start removing the bad things!

Bai Yue didn't hesitate, so he went to the river to get some fresh water and added it to the coarse salt above to make saturated salt water.

It didn't take long for them to finish the precipitation and filtration. I still use the old friend of plant ash, and there was still a lot of plant ash left when I made sugar last time, and Bai Yun put a lot of plant ash in the liquid that I got and waited for it to precipitate.

By tonight, they had been given saline with calcium and sulfate and magnesium removed.

Liu Qingxun looked at the salt water with satisfaction and said to Bai Yue: We just need to let them crystallize again! It's going to be a lot better than the salt cubes we used before.

Bai Yue nodded heavily and said: This salt block should be much more crystal clear than before, a bit like the stones produced in those caves.

When Liu Qingxun heard this, some symbols suddenly flashed in his heart, similar to the symbols that often appear in the eyes of Mr. Krabs, which are shining with golden light. Liu Qingxun sucked his tongue and said: Really? Take me there, it's sure to be some nice stones. Liu Qingxun has already imagined the scene of himself bathing in the pile of gems in his heart, hey, it's really a painful annoyance!

Bai Yue looked at Liu Qingxun like this, thinking that she was playing some crooked idea. But he was obviously wrong, Bai Yue touched Liu Qingxun's face with one paw and said: Don't think nonsense, these stones can't be eaten, although they look like candy cubes.

Liu Qingxun crossed a large group of crows in his heart and said loudly: Are you stupid? I'm not stupid enough to eat those, don't you know? These gems are very expensive, and if there is a gold mine, we will be the richest people in the entire beast world.

Bai Yue asked curiously: Is the gold mine something magical? Can we not be hungry or cold?

After listening to this, Liu Qingxun crossed a big sentence in his heart: This is the generation gap. She looked serious and said: How is it possible, the gold mine is a golden thing that can be taken with you, and it will not change color is very expensive, do you know that it costs 400 yuan a gram? If it's a whole gold mine, that's a lot of money!

Bai Yue don't say goodbye: I thought it was some kind of magical thing, it seems to be in the house, Bai Yun, you go look for it, see if you can find it?

Bai Yun got the order, and immediately began to look around the house, and then Bai Yun found a lot of golden lumps under the beds of the two of them and took them out.

Liu Qingxun looked at the glittering gold nugget in Bai Yun's hand and suddenly saw the money and said: Baiyun little baby, I didn't expect to be so rich, I'm still a big guy, my sister is good to you, hurry up and give it to my sister, give it to my sister, and my sister will buy you candy to eat.

Bai Yun stuffed the gold nugget in his hand to Liu Qingxun and said: We don't like to play this, this is too soft, there will be traces when you knock it lightly, and there are many words you want in the house for you.

Liu Qingxun smashed his tongue in his heart, it turned out that the two of them were hidden rich people, and he underestimated them, but after thinking about it, it didn't seem to be useful in the beast world as soon as possible, and it was normal for them not to pay attention to it, but he still loved the gold nuggets.

Liu Qingxun said: You guys are too tyrannical, this gold nugget is a very important liquid currency, how many pirates have lost their precious lives in search of gold coins. And you actually put it under the bed.

Bai Yue looked at his lover and liked this gold nugget very much and said: If you like us, you can go on an expedition tomorrow to find some beautiful stones and gold nuggets in your hand, but what are you going to do with these things?

Liu Qingxun then waved his hair and said: "It's a lot more useful, I want to melt them into a set of good-looking gold three, I want a big gold tooth, I want a big gold chain, I want gold armor, I want to be as noble as the ladies of the Qing Palace."

Bai Yue listened to her lover's bold speech here. Then he heard another voice: We can make some gold coins to buy and sell, you don't know the value of money, but it's very powerful. Now how many people are desperate for a piece of paper, we are taking pure gold coins!

For just a few days, Liu Qingxun spent it happily. They found a lot of stones.

Liu Qingxun was holding a large piece of turquoise in his hand, very happy, Liu Qingxun told Bai Yue to bow his head, Bai Yue really bowed his head. Liu Qingxun put the stone on Bai Yue's head, laughed and said, "You see you're wearing a green hat." It turned out that the stone that Liu Qingxun was holding in his hand was a bit like a hat.

Bai Yue took off the stone on top of his head and said: It's not cold enough to wear a hat now, and how can this stone be used as a hat? Stop playing, be careful of hitting you, do you want to take this stone with you?

Liu Qingxun said seriously: Of course you need to bring it, this is turquoise, do you understand? What is turquoise, it is much more precious than the stalactites found a few days ago, and if we find some more stones, we can paint.

Yes, you can find some stones to paint. Liu Qingxun was so excited that he said to Bai Yue: I can draw them and draw them on the stone wall of my home. It's a pity that there is no paper, but please rest assured that Bai Yue will be able to make paper and pass on the civilization.

Bai Yue looked at Liu Qingxun with an excited look, and knew that his sweetheart must have some ideas again, Bai Yue replied wryly: Then you have to paint me handsome

Liu Qingxun patted his chest and said: My husband is so handsome, he must not be ugly no matter how he paints.

Bai Yue smiled evilly: Why don't we draw Baiyun a little weirder. Angry at this little kid.

Bai Yun didn't expect that his brother had already rebelled, Bai Yue said excitedly: Doesn't he like to become a tiger for a while and a human for a while? Let's draw his tiger ears and tail! Make sure this kid jumped to his feet in anger when he saw it.

Liu Qingxun nodded with a smile and said: Of course this is excellent, I can't wait to see Baiyun turn into a little tiger to bite you.
