Early the next morning, the craftsmen who served as supervisors brought the things that Li Chengqian wanted.
However, Li Chengqian did not start work immediately. Instead, he went to the Qinghe River for a walk.
Although these commoners were still eating plain porridge and occasionally a little meat, they were already satisfied.
They thought about the days they lived before Li Chengqian came, and then they thought about the days they were living now.
It was as if one was in the sky and the other was on the ground.
Every commoner who saw Li Chengqian practically had a grateful gaze.
As for the Qinghe River, with the efforts of so many people, it had already spread far away.
Previously, when they were short of manpower, they only started to dredge upstream from Huayang City.
However, now that they had enough manpower, not only did they dredge upstream, but they also began to dredge downstream.
Li Chengqian walked around and felt very satisfied.
When he returned to his residence, Cheng Chumo got up from his bed.
Originally, he was still holding his waist and moving slowly. When he saw Li Chengqian, he immediately became energetic…
Li Chengqian was speechless.
He really cared about his face.
Suddenly, Li Chengqian thought of an interesting matter.
He asked Cheng Chumo in a low voice.
"Chumo, do you know how people in ancient times nourished their kidneys before they had any tonics?”
Cheng Chumo instantly became alert.
He glared at Li Chengqian.
He argued.
"I don't know about that!"
"Besides, what do I know about it?”
"Someone like me, who can work for a night without any problems, still needs to know about it?”
"Ridiculous!"
Seeing this, Li Chengqian sighed slightly.
"Hey."
"I have to say that the people of ancient times were really smart.”
"Although they don't have any tonics, they have a very good method to nourish the kidneys.”
"And even if the body is not weak, it can also make the body stronger.”
"But people nowadays want to use tonics…"
"This ancient technique is about to be lost."
Cheng Chumo looked at Li Chengqian eagerly. He wanted Li Chengqian to say it, but he was too embarrassed to say it.
Therefore, his face was particularly interesting.
However, Li Chengqian didn't seem to see it. He patted Cheng Chumo's shoulder and said,"
"Let's go and start our money-making business!”
Earning money?
How could Cheng Chumo still be in the mood to make money?
Right now, he wanted to know the ancient technique that Li Chengqian spoke of.
But he was too embarrassed to ask Li Chengqian directly.
Li Chengqian brought him to the back garden.
At this moment, Wang Shun and a few other eunuchs were already standing in the back garden.
They looked at the big pot in the back garden and some other things, their eyes full of doubt.
Li Chengqian didn't say anything else. He directly called them to start working.
"Wang Shun, bring some people to get a few bags of salt!”
"Then throw it into the pot to cook."
Wang Shun obediently brought his men over.
The salt of this era isn't as clean as the salt of our future generations. It contains other impurities.
Therefore, Li Chengqian wanted to refine them again and then sell them.
Of course, the target of the sale was those high-ranking officials and nobles!
After all, ordinary people were very nervous about eating salt, let alone refined salt.
Putting salt into the pot to boil was to speed up the melting of the salt in the water.
This seemed to have been mentioned in junior high school chemistry.
It didn't take long for the bag of salt to be completely melted in the big iron pot. At this time, the back garden was filled with a salty smell.
Seeing that the salt had completely melted, Li Chengqian took out two bags of things.
However, this bag was tightly sealed. Wang Shun and the others could not see what was inside no matter how they looked.
Li Chengqian directly threw the two bags into the pot and continued to cook.
About an hour later, Li Chengqian got them to put out the fire.
Then, he asked Wang Shun and the others to scoop out the salt water from the pot and pour it into the wooden barrel.
However, there were a few pieces of thick cotton cloth on the wooden bucket.
This task took a full hour.
In fact, this was the simplest filtering.
Those two bags of things were the charcoal that Li Chengqian had made himself.
Originally, he should have used activated carbon, but with the current technology, it was impossible to make activated carbon, so he could only use charcoal instead for the time being.
The effect of activated carbon was to absorb other things in the salt water, such as heavy metals...
Charcoal…barely.
Hence, Li Chengqian was only trying now. What if it worked?
After all, before he transmigrated, he had read some online novels. In them, the main character made refined salt like this!
Right now, he was just trying his best.
After filtering the salt water, Li Chengqian asked Wang Shun and the others to put the filtered salt water into the iron pot to boil.
This time, he just needed to cook it until there was no water in the pot.
Therefore, he just had to wait here for now.
At this moment, Li Chengqian had the time to observe Cheng Chumo beside him.
Cheng Chumo was now looking at him with a very resentful gaze.
Seeing Cheng Chumo's expression, Li Chengqian couldn't help but laugh.
Cheng Chumo gritted his teeth and stopped pretending. He begged Li Chengqian in a low voice.
"Your Highness, why don't you tell me?”
"I promise I won't tell anyone!”
Li Chengqian shook his head and said with a deeper meaning.
"Hey, why does my shoulder feel a little sore?”
The eyes of Wang Shun and the others, who were originally waiting by the iron pot, instantly lit up.
Just as they were about to step forward and massage Li Chengqian's shoulders, Cheng Chumo appeared behind Li Chengqian and smiled.
"Your Highness, I'm good at this!”
"When I was at home, my mother's shoulders were always sore, so I helped her massage them.”
"Come and take a look at my craftsmanship!"
Li Chengqian closed his eyes and enjoyed Cheng Chumo's service.
Wang Shun and the others looked at Cheng Chumo unhappily.
In their eyes, Cheng Chumo had stolen their chance to flatter them…
But Cheng Chumo didn't care!
After all, if what Li Chengqian said was true, then the help to him was really too great!
Err... After finishing this chapter, he still owed 23 chapters...
Good luck!
