When Haoyue came back from collecting salt soil, he saw that the emperor's father was sending Dr. Huang out.

Because he was worried that the camp would be attacked by snakes again at night, Xu Jingyang asked Dr. Huang for some medicine that could repel insects and snakes.

Haoyue thought to herself, this weather is getting colder, if it wasn't for someone deliberately putting it, there should be no more poisonous snakes in the future.

This time, Haoyue asked people to set up a large tent in the open space again, which was specially used to boil soil salt.

Since they have already made salt brine, Xu Jia and others are also handy this time.

Haoyue brought a small bench to supervise the work, and the second girl fed Haoyue some sweet berries from time to time.

Now in the eyes of the second girl, Xiao Haoyue is simply omnipotent, smart and clever, compared with the two fools in her family, one is the bright moon in the sky, and the other is the quack on the ground.

The eyes of the rest of the Xu family looking at Haoyue now are also the same as looking at a prodigy, their eyes are full of joy and fanaticism.

However, the most popular character among male dolls is Shen Yinxing, who prefers to follow Shen Yinxing to dance with knives and guns.

Today's lunch is grilled fish, which is finely smoked with lemongrass and has a unique aroma.

Although the grilled fish tastes good, anyone who eats fish and shrimp for seven or eight days in a row will get tired of eating it.

Haoyue sighed and said, alas, hurry up and boil salt to make money, and eat rice as soon as possible.

After lunch, the others were busy making salt brine, while Hatsuki collected the ashes from the grilled fish.

Then she soaked the ashes in a basin of water and exposed them to the sun.

"Huh? Sister Yue'er, what are you doing? Erya, who was playing with mud on the side, saw that Haoyue was busy, so she wanted to run over to help.

Haoyue pointed to the basin of water, and then smiled mysteriously, "I'm making magic potions." ”

"By the way, Sister Erya's hands are the most skillful, can she help weave a spoon out of rattan? It will be useful to wait. Haoyue said, taking out a few collected rattans.

"Uh-huh, no problem." Hearing that she was praised for her dexterity, Erya happily ran away with a rattan.

......

A few hours later, under the operation of several young men of the Xu family, the thick salt brine flowed down the flax bag into the wooden barrel.

The filtered salt brine was clear and clear, and Haoyue put her finger in it and dipped it in some salt water and sent it to her mouth.

Well, enough saltiness, it's time for the third step.

This third step is boiling salt, and it is also the most difficult and complicated step.

After pouring the salt brine into a large iron pot and boiling it over high heat, it immediately switched to slow burning of firewood and grass, which means tightening the fire and slowing down the fire, because it is afraid that the salt that is about to form will drift away with the hot air.

Looking at the large iron pot that was already boiling, Haoyue nodded with satisfaction, and then slowly poured a scoop of clear grass and wood ash water into it along the center of the pot.

When the boiling concentrated brine meets the ash water of plants and trees, it instantly spreads white foam in the pot, and then it should be immediately changed to slow fire, and then the saturated concentrated brine will form granular crystal salt in the process of slowly boiling.

Yue'er's operation made everyone very curious, Xu Jia pointed to the scoop of grass and wood gray water and asked, "Sister Yue'er, why do you want to add this at this time?" ”

Haoyue put the water scoop aside: "Because only by adding this scoop of grass and wood ash water, the soil salt boiled out will not eat the dead~"

This method has been tried by the Chinese people for thousands of years, and I don't know how many people have died from eating poisonous salt.

"Everyone remember, this step is the most critical step in the process of boiling salt, brine contains magnesium chloride, calcium chloride, magnesium sulfate and other toxic substances, so to add quicklime to remove, but there is no here, so it is replaced by plant ash water." Haoyue didn't care whether others could understand it or not, and she said it all in one go.

"Oh oh" everyone nodded like garlic, but they didn't really understand.

But whatever, just remember that this step requires adding grass and wood gray water....

Later, the second brother Xu Wei is responsible for adding fire, Xu Jia is responsible for stirring, stirring while cooking, and the others are ready to change hands at any time.

Time passed minute by minute, and with the boiling, a layer of white scale gradually appeared at the bottom of the pot, which is also called water alkali, which will reduce the quality of salt and need to be scooped off.

At this time, Haoyue took out the spoon that Er Ya had woven with rattan.

The craftsmanship of the second girl weaving spoon is indeed not complimentary, and the spoon weaving is loose and loose, and there are loopholes everywhere.

But Hazy Moon looked very satisfied, because what she needed was a colander....

After scooping out the limescale with a colander, wait until the pot is boiled until it bubbles and the water evaporates dry, and a layer of yellowed crystals is attached to the inner wall of the iron pot.

Haze took out the crystals with a spatula and a colander and spread them in a basket with cloth pads.

This yellowed white crystal is salt, and it doesn't look very beautiful now.

Then, Haoyue took some more water and gently sprayed it on the crystal.

The water removes the stains on the surface of the crystal, making the crystal color white.

Subsequently, Haoyue grinded the dried crystals with small stones a few times, and after a while, the crystals were crushed into grains of snow-white refined salt.

Haoyue grabbed a handful of snow-white salt grains with a salty taste and rubbed them lightly on her fingertips.

Feeling the delicacy of the salt grains at her fingertips, she also felt a sense of accomplishment in her heart.

Wow~ The first time was quite successful!

The next step is the poison test.

In fact, adding grass and wood gray water has already removed a lot of harmful substances, but for the sake of insurance, Haoyue still decided to test it.

Since there were no guinea pigs, Haoyue asked people to catch a few mice to taste.

Soon, the salted fish was divided up by the rats.

After a few hours, the rats were still alive and well.

It seems that there is really nothing wrong with this salt.

Looking at the salt grains of white flowers in front of them, ecstasy and blazing gradually appeared in everyone's eyes.

"Hahaha! You want to get rich! It's going to be rich! The crowd cheered.

You must know that this pot of soil can boil two catties of salt, and one catty of salt can be sold for two taels of silver in Dayuan!

And this raw material does not cost money, and it is inexhaustible.

Everyone looked at the salt pot again with eyes that were almost fanatical, where is this a pot of salt water, this is clearly a pot of silver!

"Haha, I'm going to get rich! It's going to be rich! Yue'er, you're amazing! The second girl hugged Haoyue and kissed her fiercely.

Others also rushed up to throw the moon high, and their excitement was beyond words.

Just as everyone was cheering, the keen Shen Yinxing suddenly turned his head to look outside the tent.

"Shh

Shen Yinxing put a finger to his mouth and motioned for everyone to be silent.

Seeing Shen Yinxing's movements, everyone understood that something was wrong outside, and immediately quieted down.

Then, Shen Yinxing moved lightly to the side of the tent, and then reached out and slammed open the door curtain.
