Qin Shi: I only work eight hours

Chapter 275 Crude Salt Refining Method

"kindness?"

"what?"

Mingzhu's eyebrows were furrowed.

Xu Lin wasn't really saving her.

They were clearly taking advantage of her unpreparedness to attack her weaknesses!
……

Three days later.

The sun was high in the sky.

After his lunch break, Xu Lin sat cross-legged at his desk, rubbing his fingers as he fell into deep thought.

I'm so bored lately.

How about we invent something else?
With that in mind, he entered the storage space.

Before long, he found the "Crude Salt Purification Method".

Then he took out the book "Method for Purifying Crude Salt" and stared intently at its contents.

The book states that the core of purifying crude salt is to utilize available materials (pottery, wood ash, limestone, linen, etc.) and achieve this through three steps: 'impurity removal, filtration, and crystallization'.

The specific steps are as follows: First, remove insoluble impurities (mud, sand, pebbles, etc.)...

After glancing through it briefly, Xu Lin nodded thoughtfully.

Then they called Yingge over.

"What are your instructions, sir?"

The parrot asked respectfully.

Go and buy some coarse salt.

"Buy more, I need them."

Xu Lin said seriously.

"promise!"

Yingge, whose black hair cascaded over her fragrant shoulders, was taken aback upon hearing this, but then immediately accepted the order.

Then she tied up her hair and rode away from the Imperial Preceptor's residence.

……

Less than half an hour later.

Parrot returned to the study with several large jars of coarse salt.

"What do you need this coarse salt for, sir?"

"Could it be that you have another new invention, sir?"

Yingge blinked her bright, clear eyes and asked.

After she finished speaking, she placed the coarse salt on the table.

Perhaps it's because the food at the Imperial Preceptor's residence is too good, but Yingge has grown quite a bit taller recently, and her chest has also gotten almost a size bigger, but her face still looks like that of a young girl!
If you only look at her face and not her figure, Yingge looks like a girl in her early teens.

If you only look at her figure and not her face, Yingge looks like a plump and beautiful woman in her thirties.

"That's it."

Xu Lin nodded.

Then the task of finding limestone and wood ash was assigned to Yingge.

"it is good!"

Parrot readily agreed.

Then he turned and left the study.

Despite her plump figure, she is very efficient and never procrastinates!
……

More than half an hour later.

When Yingge returned, Xu Lin had already begun directing Yan Lingji, Jing Ni, and others to purify the coarse salt.

There is strength in numbers.

Yan Lingji, dressed in a fiery red dress, was in charge of dissolving the coarse salt.

In front of Yan Lingji was a ceramic jar. She was filling the jar with coarse salt and pouring in water.

"Is this enough?"

Yan Lingji turned to look at Xu Lin and asked.

"almost."

Xu Lin nodded.

Then Yan Lingji placed the pottery jar on the stove.

"Keep stirring."

Xu Lindao.

After he finished speaking, he handed Yan Lingji a wooden spoon.

Heating and stirring at the same time allows the salt to dissolve fully. Sodium chloride in coarse salt is easily soluble in water, while mud and sand are not.

Jingni, dressed in a tight-fitting long dress, is making a filter.

In front of her were several clean pieces of fine-fibered linen.

Under Xu Lin's command, Jing Ni laid it on the mouth of another empty pottery jar and secured it with a rope, forming a simple funnel.

……

A quarter of an hour later.

Xu Lin instructed Yan Lingji to pour the dissolved salt water into an empty ceramic jar lined with burlap in several batches.

The linen cloth traps insoluble impurities such as mud, sand, and pebbles, while the filtered liquid flows into the earthenware jar below.

"You make the wood ash water."

Xu Lin looked up at Ying Ge and spoke.

"it is good."

The parrot nodded slightly.

Under Xu Lin's instructions, she put the wood ash into a ceramic jar, then added water, stirred, and let it stand before taking the clear liquid from the top.

Xu Lin asked Yingge to do this because the book said that the upper clear liquid contains carbonate ions, which can react with calcium ions to form calcium carbonate precipitate.

Then, Xu Lin waved to Li Wu and Li Ji.

The task of making lime milk was assigned to Li Wu and Li Ji. Under Xu Lin's command, Li Wu placed the limestone in a kiln and calcined it at high temperature to produce calcium oxide, which is quicklime. Then, she added water to the quicklime and stirred it to produce calcium hydroxide, which is lime milk.

The book states that lime milk contains hydroxide ions, which can react with magnesium ions to form magnesium hydroxide precipitate.

……

Three days later.

Thanks to the tireless efforts of Xu Lin, Ying Ge, and others, they finally refined the coarse salt into fine salt.

The fine salt looks like snowflakes in winter, it's so pretty!
"Can I have a taste?"

Yingge blinked her bright, clear eyes and asked.

"of course."

Xu Lin nodded.

Upon hearing this, Yingge tried tasting the fine salt.

The moment the fine salt touched her tongue, her beautiful eyes lit up.

Fine salt not only looks better, but also has a purer taste and no bitterness.

Coarse salt not only looks unappealing, but it also tastes bitter and astringent, and eating it directly will result in a noticeable rough texture and unpleasant odor.

"How did you come up with the idea of ​​using limestone and wood ash to purify coarse salt?"

Yingge handed the fine salt to Jingni and asked curiously.

Yan Lingji was also very curious about this.

Li Wu, Li Ji, and the others smiled upon hearing this.

They've gotten used to Xu Lin's various inventions!

"Obtained in a dream."

Xu Lin answered calmly.

"A divine being appearing in a dream?"

Yingge frowned slightly, thinking to herself.

After a moment's hesitation, she rolled up her sleeves and went to the kitchen to cook.

The appearance of fine salt made Yingge appreciate Xu Lin even more!
……

Half an hour later.

Twilight Quadruple.

Yingge carried the dishes to the study.

While cooking, she secretly tasted a few bites. The same seasonings and cooking time, only the addition of fine salt, made the dish taste much better!

You are truly a man of unparalleled talent!

……

An hour later.

After taking a bath, Yingge lay down on the soft couch.

She doesn't like to wear too many clothes to bed, so she only wore a very thin nightgown.

Although the temperature is not as high as last month, the humidity is still too high, so it is still very stuffy at night.

Therefore, Yingge only covered her lower abdomen with a brocade quilt.

……

After a cup of tea.

Parrot faintly heard footsteps.

Squeak.

The wooden door was pushed open a crack.

A dark figure slipped in and slowly walked towards Yingge.

Parrot tried to turn to look, but found that it couldn't move!

After more than ten breaths, the dark figure climbed onto the soft couch and placed his hand on her lower abdomen.

Yingge looked up with difficulty and discovered that the person who came was Xu Lin.

"gentlemen?"

Yingge's eyebrows furrowed tightly.

She had thought this day would come, but she didn't expect it to come so soon!

And for some reason, in Xu Lin's eyes, she seemed not to have woken up yet.

Xu Lin raised his right hand and waved it in front of her.

Then he lifted the quilt and placed his hand on her fragrant shoulder.

With his left shoulder fully exposed, Xu Lin's advances were like fire, making Ying Ge blush.

"Why so small?"

Xu Lin looked at the center of Ying Ge's violently heaving chest and asked with a smile.

No sooner had he finished speaking than Xu Lin divided his forces into three groups and launched a second attack.

……

Half an hour later.

Yingge's eyebrows furrowed tightly, her thin lips bitten hard, and she woke up, unable to bear it any longer.

She found the bedroom empty except for her own restless hands.

This relieved the sweating parrot.

“It was just a dream.”

"It's a parrot," the song murmured.

Then, she sat up with the help of the soft couch, wiped the sweat from her neck with straw paper, picked up the teacup, and drank the boiled water in it in one gulp.

Then she got out of bed, put the soiled sheets into a bamboo basket, grabbed a new nightgown from the wardrobe, and went to the bathroom with the bamboo basket.

Yingge had only taken a few steps outside when she ran into Xu Lin, who was washing his hands after using the restroom.

"Didn't you just take a shower?"

Xu Lin looked in the direction of the sound and saw Ying Ge with her hair in strands, her nightgown clinging to her body, and carrying a bamboo basket in her hand. The basket seemed to contain a bed sheet. He smiled and asked.
