"My father has made an urgent report to Your Majesty about making salt." Wang Lilao said after a long time, unable to understand what Zhao Si was drawing.
"Well... I think it will be almost done when His Majesty returns to Xianyang." Zhao Si nodded.
It was just an experiment before, but if it were to be used in large-scale production, it would definitely be impossible to filter it with cloth, and it would also be impossible to continue to use firewood to boil the water to produce salt.
Cloth was quite expensive in this era, and firewood was not expensive in this era, but it was by no means cheap. The reason why salt is expensive today is that the coastal areas where most of the salt is produced still use the boiling salt method instead of the sun salt method.
"Speaking of which..." Wang Li moved to Zhao Si's side and said.
"Haven't you remembered where home is?"
I had been in contact with Wang Li for a few days, and naturally I also discussed the issue of place of origin. Zhao Si still dealt with it by saying that he hit the sea and hit his head in a storm.
In fact, he couldn't remember anything. He had no memory at all when he traveled through time.
He couldn't even speak or understand. As for the name, I also learned that my name is Si from other children. Because he couldn't remember his last name and was not used to not having one, Zhao Si happened to have a wooden plaque with the character Zhao engraved on it. He thought it was some kind of amulet, so he simply called himself Zhao Si.
It sounds the same as Nicholas Zhaosi's name, which can somewhat remind him that he is a time traveler.
At that time, Zhao Si was at sea, surrounded by many children of the same age, and with the help of Golden Finger, Zhao Si was able to slowly overcome the difficulties.
From the initial continuous speaking to gestures, and finally to speaking fluently in the local dialect.
It is worth mentioning that the Mandarin in Xianyang is not like the modern Shaanxi dialect.
The times are so different. When Zhao Si first arrived, speaking the truth was almost the same as listening to foreign languages.
"I sent someone to inquire. I haven't heard of a boy named Zhao Si around Xianyang." Wang Li said.
Thanks to the excellent official administration of the Qin Dynasty, for large-scale corvee services like this, basically local governments have records and records of the names of local service personnel.
"But I found a few names on the list you gave me. I don't know if they are correct or not." Wang Li said.
Zhao Si asked Wang Li to help with the investigation of the ashes of the deceased crew member.
There were many crew members who only had names and unclear place of origin. Zhao Si didn't know where to bury them, so he simply asked Wang Li to check and see that there was no corresponding person in Xianyang.
"Send it over for me!" Zhao Si said.
"We haven't found out yet. There may be duplicate names or something." Wang Li said.
"They themselves can't remember their place of origin, and even if they have the same name, as long as they went to sea with the ship, those who have not returned now will either stay in Fuso or die at sea. Even if they have the same name, no one can tell them apart. "Zhao Si said.
He wasn't trying to fool around.
But for those who went to sea and did not come back, even if they stayed in Fusang, it would not be much different from death to their relatives here.
Regardless of whether they have the same name or not, sending the ashes back will bring comfort to both parties.
Finally, we wouldn’t just bury the ashes of those crew members who couldn’t remember their place of origin. If they really had the same name and surname, they would be recognized as godson by such a predestined relationship.
After all, there are no cameras in this era, and the crew members have even lost their own biographies. In this case, it is impossible to be 100% sure that nothing is wrong.
It is the limit of this era to be able to match the name with the list of people who are going to serve overseas. If there are duplicate names, it can only be said to be fate.
This is the end of the matter.
"That's it, you give me their relics and I'll send someone to deliver them." Wang Li nodded.
There are not many names on the local correspondence in Xianyang. The three thousand boys and three thousand girls who were fishermen who went to sea are scattered all over the place. Wang Li took away a few, leaving dozens of jars to Zhao Si.
"Thank you!" Zhao Si stood up and bowed.
In the next few days, Zhao Si was busy formulating his own mathematical formulas.
The main reason is that this thing has not been used for too long, and many of them have been blurred in memory.
But after all, I learned it once, and if I concentrate on recalling it, it’s not that I can’t recall it. It’s just that many of the memories are fragmented and vague.
After Zhao Si figured it out, he was not sure whether it was right or wrong, so he had to go back and check the formula several times.
Checking the calculation once is simply not enough, because sometimes the wrong formula can achieve the correct result by chance.
Pythagorean theorem
triangle inequality
Circle area calculation formula
Circle circumference calculation formula
parabola equation
cone volume area
volume of sphere
Zhao Si remembered a lot of things, and they were very complicated. Even some formulas were clearly correct after repeated verification. Zhao Si still felt that what he wrote was not the same thing as what he had learned in the first place.
Zhao Si checked all the ones that were certain.
If you still feel something is wrong after verification, put a question mark on it.
At Zhao Si's current level, it is definitely impossible to prove whether the formula is right or wrong based on the principle of reverse reasoning.
Zhao Si even couldn't remember the principles of many formulas at all. He simply remembered the formulas.
There is no way, Zhao Si's level can only be like this. As for the principles, we can only wait for people of this era to learn and continue to fill in.
For more than ten days in a row, Zhao Si and Wang Lilao not only met and looked at the tools that the craftsmen had prepared, but also memorized and verified these mathematical formulas.
After all, it was something I had learned once, and Zhao Si’s math scores were pretty good at the time. It was normal for him to not be able to remember it for a while. If he concentrated on thinking about it for ten days, he would always be able to remember something.
Zhao Si has basically thought of the main volume and area calculation formulas. These are things that can be used daily, and they are also very practical.
Some of the more profound ones cannot be remembered clearly, and some are not sure for sure, but Zhao Si also recorded them all.
"It's finally over!" Zhao Si sighed as he looked at the messy papers in front of him.
Mathematics is really a headache to learn. I didn't expect that I would have to go through Da Qin and have to endure torture again.
"Done?" Wang Li said excitedly from the side.
"I can't remember the rest." Zhao Si nodded and looked confused at Wang Li's happy face.
"Why are you so happy?"
"If it doesn't work out, I won't have any money..." Wang Li rolled his eyes.
Zhao Si came to farm, not to engage in literary creation. It would be understandable if he used bamboo slips to reimburse his military expenses. However, Zhao Si used silk, which was much more expensive than bamboo slips.
"So expensive?" Zhao Si was stunned when Wang Li cried out about poverty.
"The silk you spend these days is enough to buy a big house in a high-end area of Xianyang City!" Wang Li said.
Because Zhao Si needed to constantly check calculations and make mistakes, writing on bamboo slips was not smooth enough, so he asked Wang Li if he had any more convenient writing materials. Wang Li got the silk without saying anything.
That was because he didn't expect Zhao Si to use it all the time, and he didn't feel bad at all. This thing was a luxury item, very expensive, and there was no way to reimburse it. Wang Li paid for it all out of Zhao Si's own pocket.
Zhao Si himself only knew that fine silk would be more expensive, but he never expected it to be as expensive as Wang Li said. He really didn't know much about prices in this era. After arriving in Daqin, apart from crossing the ocean, Zhao Si didn't even go to the market after landing, so it was impossible to know the specific price of silk.
Now after listening to Wang Li's words, Zhao Si felt heartbroken.
"Can this thing... be sold after cleaning?"
