"Are the things ready?" Lin Zhibai asked Zhang Hai.

Since Zhang Hai was summoned by Lin Zhibai, he has been particularly rare in this opportunity, so he naturally did not dare to neglect Lin Zhibai's instructions at all.

Hearing the inquiry, he quickly said respectfully: "Report to Your Highness, all the slaves you want are ready, and they are all there."

While speaking, Zhang Hai pointed to a bunch of things placed in the yard.

Lin Zhibai glanced at it and was basically complete. He said, "You can move the things into the empty room next to you, then light the candles to light it. By the way, the wooden barrel was made and half a bucket of water, and the charcoal stove also rose."

Zhang Hai took the order and hurriedly brought several other eunuchs to move all the things into an empty room next to Lin Zhibai's bedroom.

The fire candle is lit up and the dark room is bright.

Then the fire was set up and the charcoal furnace was lit up.

When the preparations were ready, the crowd saw Lin Zhibai starting to tinker with the pile of things he had just moved in.

First, the inferior coarse salt that was grayish-black and light yellow in color, as well as the green salt with relatively few impurities, were poured into the wooden barrel containing water.

Then I took a funnel, started laying gauze on it, and stuffed some river sand into it.

The first funnel is made, the second funnel is covered with cotton cloth, followed by the third funnel, stuffed with gauze wrapped with charcoal.

On the side, Zhang Hai couldn't understand what Lin Zhibai was doing, but he asked with concern: "Your Highness, what are you doing? But what do you need help from me?"

Lin Zhibai was busy without raising his head: "Purify coarse salt to create refined salt with pure taste without astringent impurities."

Not long ago, I accidentally heard that I spent a lot of money on martial arts, so I actually asked Queen Zhao to pay for her private money.

Although Queen Zhao's dowry was quite abundant, and the industry brought continuous benefits, and the large amount of salary that Emperor Longxing granted to Lin Zhibai for martial arts practice, it could still be maintained for a period of time.

But it's okay once or twice. If this continues for a long time, Empress Zhao will definitely be implicated and bankrupt by Lin Zhibai.

After all, Lin Zhibai’s martial arts practice is not a one-time investment, but a continuous consumption over the years, and there is no output for the time being, which means he has been lying on his parents.

Lin Zhibai was even calculating that when he grew up, his body had a stronger ability to withstand strength, he could change to some more powerful but more expensive tonics to assist in practicing.

Although Queen Zhao didn't mind and planned to fully support Lin Zhibai in practicing martial arts, Lin Zhibai felt a little sad.

The economic way is nothing more than increasing revenue and reducing expenditure.

Lin Zhibai did not want to reduce his expenses, slow down his practice, nor did he want to rely on his parents.

So, I had the idea of ​​making money.

Now, the method of making fine salt is a method that Lin Zhibai puts high hopes on after thinking for a long time.

In ancient times, salt trading was profitable, so even the country regarded it as an important source of financial and economic. At this moment, if Lin Zhibai made the fine salt, he would definitely sell it for sale and earn huge amounts of wealth.

He was born in the royal family and he sold salt was an official salt. Who dares to say anything?

At that time, no matter how much Lin Zhibai spends on martial arts training, it will be drizzling in the face of this huge income.

It is hard to say that you can spend a lot of money to buy huge amounts of treasures for food and become legendary masters early.

Even breaking through the legendary level and becoming an existence above the legend.

Then turn the tide when it falls, and support the building to collapse.

With this expectation, Lin Zhibai racked his brains to recall the knowledge he had returned to the chemistry teacher for decades of middle school, and was ready to put it into practice.

...

Zhang Hai was a little confused when he heard Lin Zhibai say he wanted to make fine salt.

He understood every word Lin Zhibai said, but it made him confused when they were connected.

"Is there any astringent salt? Even the best green salt has a astringent smell, right?" Zhang Hai said in surprise.

In his perception, although salt is a necessity for life, people will definitely die if they don’t eat salt for a long time, but the taste of salt is salty and astringent.

This is not surprising.

Even Lin Zhibai's previous life, the purification method of refined salt was studied and purified after modern science was developed. People mastered the corresponding chemical knowledge before they could study and purify it, let alone in this ancient era where the scientific and technological level was backward.

After getting the gauze done, Lin Zhibai spoke to Zhang Hai: "Aren't you going to help? Go and pour this bucket of salt water into this funnel and filter it."

Zhang Hai did as he said.

Then, under Lin Zhibai's command, the salt water that had been filtered once with river sand was poured into a funnel paved with cotton cloth, and the salt water was inserted into another bucket along the funnel.

This time, some fine sand impurities were left on the cotton cloth.

Finally, Zhang Hai was directed by Lin Zhibai and filtered for the third time, pouring the salt water into a funnel wrapped in gauze and charcoal.

The previous two filtrations were used to remove impurities, and this step was to absorb odors.

After such a process, although the refined salt produced is not as good as modern industrial salt, it is also very close.

This method is not only suitable for the current refined coarse salt, but also allows for direct digging and operation, and the cost is not very high.

Zhang Hai still doesn't understand the significance of Lin Zhibai's series of actions. After mechanically completing three filters with the command, he looked at Lin Zhibai blankly.

"Put the salt water into the pot in batches and cook more quickly."

Facing Zhang Hai's confused gaze, Lin Zhibai gave a concise order.

As Zhang Hai did as he did, he soon saw the salt water in the pot boiling, and its water gradually evaporated to dryness at high temperature, revealing fine snow-white salt particles.

In terms of appearance, it is many times stronger than the coarse salts before.

This batch of fine salt was successfully manufactured.

Seeing this, Lin Zhibai breathed a sigh of relief.

I have been reincarnated in this life for a few years. In terms of actual life experience, I am almost the same as the physical rules of my previous life, but it is difficult to ensure that some details are different.

What if the world uses the same coarse salt purification process not only fails to produce fine salt, but instead turns ordinary coarse salt into poisonous salt?

But now it turns out that the difference between the two worlds is not that big.

Lin Zhibai took a porcelain bowl and put the prepared salt grains, picked up a little and tasted it. A pure salty smell appeared on the taste buds, and then nodded with satisfaction and said, "The refined salt has been purified successfully."

He asked someone to take another plate of meat slices, and Lin Zhibai took a piece of it and ate it with a little salt.

This time the comparison result is more intuitive, basically not much different from the salt Lin Zhibai ate in his previous life.

Seeing that Zhang Hai was curious, Lin Zhibai handed over the porcelain bowl.

Zhang Hai also took a piece of meat and tasted it with salt, then widened his eyes and said, "Your Highness, this salt is as salty as you said, it is pure and salty, melts in your mouth, without any impurities or astringent taste!"

The salty taste is pure and has no impurities, and even the taste of an ordinary piece of meat will instantly improve a lot.

This made Zhang Hai, who had eaten salt for the first time, feel extremely amazing.

That's right.

Lin Zhibai put down the porcelain bowl and asked with a smile: "How much is the salt price in Beijing now?"

Upon hearing this, Zhang Hai quickly replied: "Report to Your Highness, the price of salt in Beijing is now fifty cents per catty, but this is just inferior coarse salt. High-quality green salt is more expensive, and a full 200 cents per catty."

The Dahua Dynasty used copper coins, silver and gold as currencies.

Gold is extremely rare, and silver is relatively rich, so people often use silver and copper coins in daily life.

One thousand coins are Yishen, which is equivalent to one tael of silver.

Hearing this, Lin Zhibai smiled and said, "Then my salty tastes pure and free from impurities and astringent taste. Is it worth selling for 500 yuan per pound?"

Zhang Hai nodded wildly: "It's worth it, it's so worth it, it may cause a snatch."

Salted salt is just a daily routine for modern people, but it is a rare enjoyment for people of this era.

And anything that can make people happy can always be sold at a high price.

Millions of wealthy families in the Dahua Dynasty, even if each person buys only one pound of salt, will generate huge profits.
