"Wait a moment, I'll see if there are any more poisonous salt blocks at home.”
As she spoke, Han Qiu started rummaging through the salt storage jar.
"Brother, are you sure you want to do it?" asked Chang Le suspiciously. Let's make coarse salt."
"No, we agreed on poisonous salt. Moreover, I want Little Li to be my lackey.”
As Han Qiu spoke, she took out a few pieces of poisonous salt from the jar.
These poisonous salt were yellow and brown, and one could tell that they could not be eaten just by looking at their appearance.
However, Han Qiu did not care.
"Xiao He, help me prepare a stone mill, wooden bucket, clean water, wooden stick, cotton cloth, charcoal, funnel, iron pot, these tools.”
Xiao He was very obedient.
He immediately turned around and started looking for these tools at home.
Han Qiu had made refined salt before, so these tools must be ready-made at home.
After about ten minutes, Xiao He ran in and said,""Young Master, the items you want are ready. They are outside the door.”
Han Qiu made an inviting gesture and said,"Little Li, please follow me."
"I'll come then. Do you think I'll go back on my word?”
Li Chengqian snorted coldly. He leaned on his crutch and limped out of the door.
He did not believe that Han Qiu had the means to purify the poisonous salt!
The extraction process was relatively complicated and required a fire. Han Qiu naturally arranged for them to be in the open space outside the door.
Han Qiu threw a few pieces of poisonous salt into the hole of the stone mill and asked Xiao He to shake the mill for him.
Soon, brown salt ore powder flowed out from the edge of the stone mill.
Han Qiu carefully poured the mineral powder into a wooden bucket filled with clean water and kept stirring it with a wooden stick.
"Brother Qian, now is not the time to be angry.”
Chang Le reminded Li Chengqian carefully.
If Han Qiu could really purify the poisonous salt, how could it be extraordinary?
It could even be recorded in the annals of history!
Of course, Li Chengqian was not stupid. His eyes were fixed on Han Qiu's operation.
Han Qiu kept adding salt powder into the water, allowing the salt to fully fuse into the water. Soon, the solution reached saturation.
Immediately after, Han Qiu took a new wooden bucket, covered it with two layers of cotton cloth, and poured the saturated solution into the bucket.
"Do you see the black dregs on this cotton cloth? These are toxic substances and impurities."
Han Qiu pointed at the filtered impurities on the cotton cloth.
Li Chengqian didn't believe it and lifted the cotton cloth.
The water in the new bucket had turned brown, and the color was much lighter.
This method was indeed effective!
"So that's how it is. Will it become clear after repeating it a few times?”Chang Le asked.
"That's right, you can try."
Han Qiu smiled and pointed at the brown solution in the new wooden bucket.
"Then I won't stand on ceremony, hehe.”
Changle volunteered.
She wanted to learn how to purify the poisonous salt herself!
Just like Han Qiu, Chang Le covered the wooden barrel with two layers of cotton cloth and poured the brown solution into it.
This repeated.
The color of the solution became lighter.
"This is refined salt? Let me try it."
As he spoke, Li Chengqian placed a drop of the solution into his mouth.

"Bah!" Li Chengqian's expression was extremely ugly as he scolded,""What the hell is this? It's so bitter!”
Han Qiu was speechless.
"Who let you eat? This solution hasn't been completely detoxified!"
Puff!
" What?!"
Li Chengqian was stunned. His small eyes were filled with pity and helplessness.
He seemed to be saying, why didn't you say so earlier?
"Ouch! My stomach hurts. Go to the toilet. Where is the toilet?”
The poisonous solution quickly stirred in Li Chengqian's stomach.
Li Chengqian couldn't take it anymore. He clutched his stomach and limped towards the toilet.
"Brother Qian, will he be alright?”Chang Le asked worriedly.
"It's fine. This solution is poisonous, but it's almost filtered out. The small amount he took could only make his stomach run.”
Hearing Han Qiu's words, Chang Le's anxious heart finally relaxed.
"Then how should I remove this last bit of poison?”
"Well, Xiao He, light the fire!"
Under Han Qiu's instructions, Xiao He quickly set up an iron pot and started a fire.。
While the fire was still burning, Han Qiu poured the solution into the pot and boiled it.
During the process, the firewood burned with crackling sounds. The fire burned brighter and brighter, and the water in the pot became less and less.
In the end, the poisonous water evaporated, and crystals began to appear at the bottom of the pot at a speed visible to the naked eye.
"This is green salt!"
Changle shouted excitedly.
Xiao He also started dancing.
It turned out that the refined salt that Han Qiu was talking about was the high-grade salt in their imperial palace, green salt!
Green salt was the best salt that the Great Tang could produce. It could only be produced in Shandong, Binhai, and other places. The process was tedious and the output was extremely low.
The princes and princesses also had some in their residences, but they only used it to rinse their mouths every day.
"Oh? Green salt can't compare to my salt." "Try it if you don't believe me," Han Qiu said proudly.”
"Better than green salt?"
Chang Le didn't believe him and put a piece of salt into his mouth.
In the end, after a few seconds, her delicate little face was filled with surprise.
Then, he turned around and looked at Han Qiu with admiration.
"Brother, you're amazing! You're really the Prince Charming in my heart!"
Han Qiu waved her hand and said casually,"Small tricks, not worth mentioning."
Unknowingly, he had put on a cross in front of his sister.
However, he only stopped at pretending and did not have any other thoughts.
After all, she was his biological sister.
But Chang Le didn't think so. Unknowingly, as a princess, she was obsessed with a country boy.
If Han Qiu knew what Chang Le was thinking, she would definitely complain loudly.
I treat you as my biological sister, but you want to be my wife?!
