Daqin: When I return from sea, I will offer you a map of the world

Chapter 33 Expensive Silk

"The matter of making salt, my father has rushed to play it to His Majesty." Wang Li said for a long time because he couldn't understand what Zhao Si was drawing.

"Well... When His Majesty returns to Xianyang, it will be almost done." Zhao Si nodded.

It was just an experiment before, and if it is really going to be used in large-scale production, it is definitely impossible to filter it with cloth, and it is impossible to continue to boil the dry water with firewood to get the salt.

Cloth was quite expensive in this era, but firewood was not expensive in this era, but it was by no means cheap. The reason why salt is expensive today is because the coastal areas that produce most of the salt still use the method of boiling salt instead of drying it.

"Speaking of which..." Wang Li moved a few times beside Zhao Si and said.

"Haven't you remembered where home is?"

Having been in contact with Wang Li for some time, naturally they also talked about the issue of their native place, but Zhao Si still pretended that he had hit his head in a storm when he went out to sea.

In fact, he couldn't remember at all, he had no memory at all when he traveled.

He couldn't even speak or understand the words.As for the name, I also learned that my name is Si from other children.Because he couldn't remember his surname and was not used to not having a surname, Zhao Si happened to have a wooden sign engraved with the word Zhao, presumably it was some kind of amulet, so he simply called himself Zhao Si.

It sounds the same as Nicholas Zhao Si's name, and it can somewhat remind him that he is a time traveler.

At that time, Zhao Si was at sea, surrounded by children of the same age, and with the help of golden fingers, Zhao Si was able to slowly overcome the predicament.

From the very first words to gestures, to the fluent local dialect at the end.

It is worth mentioning that Xianyang's Mandarin is not like the modern Shaanxi dialect.

The time difference is too long, and Zhao Si is just like listening to a foreign language to be honest.

"I sent someone to inquire about it, and there is no one in Xianyang who is called Zhao Si to serve in the army." Wang Li said.

Thanks to the excellent official administration of the Qin Dynasty, like this kind of large-scale corvee, basically the local governments have specific records and records of the names of the local service personnel.

"However, a few names were found in the list you gave, and I don't know if it's right or not." Wang Li said.

What Zhao Si asked Wang Li to help was to investigate the ashes of the deceased crew members brought back.

There are many crew members who only have names and their origins are unclear. Zhao Si didn't know where to be buried, so he simply asked Wang Li to check and see if there is no corresponding person in Xianyang.

"Send it there for me!" Zhao Si said.

"I haven't found out yet, there may be duplicate names or something." Wang Li said.

"They can't remember their own origins clearly, and even if they have the same name, as long as they went out to sea with the ship, those who haven't returned will either stay in Fusang or die at sea. Even if they have the same name and surname, no one can tell the difference. " Zhao Si said.

He wasn't trying to fool things.

It's about going to sea, and those who didn't come back, even if they stayed in Fusang, for the relatives here, it's not much different from death.

Regardless of whether they have the same name or surname, if the ashes are sent back, there will be comfort for both parties.

After all, it is not possible to bury the ashes of the crew members who can't remember their origins. If they have the same name and surname, they have the right to recognize their relatives if they are destined.

After all, there are no cameras in this era, and the crew members have even lost their test records. In this case, it is impossible to be 100% sure.

It is the limit of this era to be able to match the name with the list of sea envoys. Duplicate names can only be said to be due to fate.

This matter has been done here.

"That's it. You give me their relics, and I'll send someone to deliver them." Wang Li nodded.

There are not many names corresponding to the local area in Xianyang. Three thousand virgin boys and three thousand virgin girls from the fisherman went to sea, all over the place. Wang Li took a few away, and Zhao Si left dozens of jars.

"Thank you!" Zhao Si got up and bowed.

For the next few days, Zhao Si was busy working out his own mathematical formulas.

The main reason is that this thing has been useless for too long, and many of them have been blurred.

But after all, I learned it once, and I concentrated on recalling it. It's not that I can't recall it, it's just that many memories are fragmented and vague.

After Zhao Si figured it out, he wasn't sure if it was right or wrong, and he had to go back and check the calculation several times according to the formula.

It is not enough to check the calculation once, because sometimes the wrong formula can achieve the correct result by chance.

Pythagorean theorem
triangle inequality

Circle Area Calculation Formula

Circumference Calculation Formula

parabolic equation

cone volume area

sphere volume
Zhao Si recalled a lot of things, and they were very complicated, and even some formulas were proved to be correct after repeated verification, but Zhao Si still felt that what he wrote was not the same thing as what he had learned at the beginning.

For those who were sure, Zhao Si put a checkmark on them.

If you still find it wrong after verification, put a question mark on it.

With Zhao Si's current level, it is definitely impossible to infer the right or wrong of the principle proof formula.

Even Zhao Si couldn't remember the principles of many formulas at all, and simply remembered the formulas.

There is no way, Zhao Si's level can only do so much, as for the principles and so on, it can only be filled in after people of this era learn.

For more than ten days in a row, apart from chatting with Wang Li, Zhao Si would look at the craftsmen's neatly crafted tools, recalling and checking these mathematical formulas.

After all, it was something that I had learned once, and Zhao Si had good grades in mathematics back then, so it was normal that I would not be able to remember it for a while, but after ten days of concentrating on it, I would always be able to remember something.

The main volume and area calculation formula Zhao Si has basically thought about, these are things that can be used in daily life, and they are also very practical.

Some of the more esoteric ones are unclear, and some are not sure, but Zhao Si also recorded them all.

"It's come to an end!" Zhao Si sighed as he looked at the messy paper in front of him.

Mathematics is really a headache to learn. I didn't expect that I would have to suffer again after traveling through the Great Qin Dynasty.

"It's done?" Wang Li asked excitedly from the side.

"I can't remember anything else." Zhao Si nodded and looked at Wang Li's happy face with some doubts.

"What are you doing so happily?"

"If it doesn't work out, I'll have no money..." Wang Li rolled his eyes.

Zhao Si came here to farm, not to engage in literary creation, so it would be understandable if he used bamboo slips to travel to the army for reimbursement, but Zhao Si used silk, which was much more expensive than bamboo slips.

"So expensive?" Zhao Si was a little stunned when he heard Wang leave his mouth crying poorly.

"The silk you use these days is enough to buy a big house in a high-end area of ​​Xianyang City!" Wang Li said.

Because Zhao Si had to constantly check the calculations and try and make mistakes, writing on the bamboo slips was not neat enough, so he asked Wang Li if there was no more convenient writing material, and Wang Li got the silk without saying a word.

It was unexpected that Zhao Si used it all the time, and didn't feel bad at all. This thing is a luxury item, very expensive, and there is no way to reimburse it. Wang Li paid Zhao Si's own money.

Zhao Si himself only knew that silk would be more expensive, but he never expected that it would be as expensive as Wang Li said.He really doesn't know much about prices in this era. After arriving in Daqin, except for crossing the sea, Zhao Si didn't even go to the market after landing, so it is impossible to know the specific price of silk.

After listening to Wang Li's words now, Zhao Si only felt distressed.

"This thing... can it be sold after washing?"
