"Erlang, are you having dinner here today?”Empress Zhangsun asked.
"Alright, here it is. Zhen is giving face to Little Dou Zi, not to Slave Zhi.”As he said that, Li Shimin even smiled at Li Zhi.
Li Zhi shook his head in disdain.
He felt that Li Er was too childish.
"Imperial Father, your mouth is really too smelly!”
"When you have nothing to do, brush your teeth more!”
"Oh, right, remember to use refined salt. Don't use coarse salt.”
Li Shiming was so angry that he wanted to step forward and kick Li Zhi's butt!
However, Li Zhi swaggered and pulled Xiao Dou to the side to play.
"This bastard! I only see that he's young! If he was older and still dared to speak to me like this, I would definitely teach him a lesson!”Li Shiming complained to Empress Zhangsun.
Empress Zhangsun nodded gently." Erlang, ChenQie believes in you. However, Slave Zhi was still too young and ignorant. When he grew up, he would definitely be sensible.”
In the pit beside him. Li Zhi was planting flowers with Xiao Dou!
"Guoguo, what's the refined salt you mentioned just now?" Little Douzi asked curiously.”
Little Dou Zi was only two years old at this time, and it was the age where he was curious about everything!
Li Zhi explained in a childish voice,
"Refined salt is a type of salt! The salt that the commoners ate was mostly coarse salt, which had many impurities.”
"And in our palace, we mostly eat fine salt! Fine salt didn't have too many impurities, but there were still impurities!”
"There are even heavy metals mixed in! Eating too much heavy metal would kill you!”
Xiao Dou Zi listened very seriously. She felt that it was very interesting!
Moreover, Xiao Dou Zi trusted her brother very much, so no matter what Li Zhi said, she would believe it!
Li Shiming and Empress Zhangsun were standing at the side!
At this moment, they were quite shocked when they heard this conversation.
"Heavy metal? What is this?"
"There are heavy metals in the fine salt we eat?”
"If you eat too much, will you die?"
"Doesn't that mean that if we eat too much fine salt, we will be poisoned?”
Li Shiming quickly understood the meaning behind the words!
Empress Zhangsun nodded slightly, but soon shook her head.
"Your Majesty, this servant is only three years old. How could he know so much?”
"I'm afraid that this is all nonsense made up by Zhicu! You don't have to take it seriously!"
Li Shi Min gently nodded.
That was true.
I'm only three years old!
He couldn't possibly know how to make salt!
Just as Li Shiming was thinking about this, Xiao Dou Zi suddenly raised his head and asked Li Zhi,
"Guoguo! If we eat too much fine salt, will we die?”
Li Zhi nodded seriously.
"Of course! Of course he will die!"
"That's why we have to eat refined salt!"
"Refined salt is salt without heavy metals and other impurities!”
Hiss!
Li Shiming and Empress Zhangsun both gasped!
Salt without any impurities?
In this world!
Could there really be such salt?
Li Shiming and Empress Zhangsun were very suspicious! However, the two of them held their breaths and continued to eavesdrop on the conversation between Li Zhi and Little Douzi!
Xiao Douzi clapped happily." Oh! The refined salt is so powerful! Guoguo, I want to eat refined salt too!"
Li Zhi nodded heavily." Don't worry, Little Dou! I still lack a mountain of salt. When I have a mountain of salt, I'll make refined salt and make you the first person to eat refined salt!”
"Oh! Guoguo is the best! Guoguo is the best!" Xiao Dou Zi was even happier.
"However, Guoguo, how do we make this refined salt? I heard that salt production is done by the sea?”
Li Zhi waved his hand and said in a childish voice,
"If I were to make salt, why would I need to go to the seaside?”
"The reason why we're making salt by the sea is because most of the salt in the Great Tang is extracted from sea salt.”
"But our Great Tang's Guanlong region has many salt mines. However, these salt mines were known as poisonous salt mountains. The commoners thought that they were poisonous and did not dare to touch them!”
"Actually, we can use the salt ore on this mountain to produce a large amount of refined salt!”
Using salt ores to produce a large amount of refined salt?
Li Shi Min was stunned!
If what Li Zhi said was true, then there were ten salt mines in the Guanlong area that Li Shimin knew of!
These salt mines could not grow crops at all, so no one wanted them.
Sometimes, Li Shimin would feel that it was too shabby to use these salt mines to reward his officials.
If he could really use it to make large amounts of refined salt.
That would be wonderful!
In an instant, the salt mines would turn into 'gold mountains'!
Li Shi Min became more and more excited!
Even Empress Zhangsun wanted to speak, but Li Shimin stopped her." Guanyin Maid, be quiet and listen carefully to Slave Zhi!"”
At this moment, Slave Zhi's words became extremely important in Li Shiming's heart.
Li Zhi's childish voice continued,
"You can first use an iron pot to boil water and boil it until it boils. Then, you can put the salt ore into the iron pot!”
"There are many chemicals in the salt ore. If you only evaporate it at high temperatures, there will still be many toxic chemicals.”
"Therefore, after high-temperature evaporating and analyzing, it can only be made into coarse salt or fine salt.”
"But this kind of salt can't be eaten directly.”
"At this time, we need a very important chemical process!”
"That is to mix it with bittern and evaporate it!”
"In that case! You can make refined salt!"
Chemistry…
Evaporized…
Brine…
Chemistry…
Li Shiming and Empress Zhangsun listened very seriously! But the more he listened, the more confused he became.
It felt like he was listening to a heavenly book!
However, he felt that it was amazing!
They felt that what Li Zhi said made sense!
"My son! Truly a genius!"
