"My father has made a haste to play the matter of making salt, and it will be played to Your Majesty." Wang Lilao couldn't understand what Zhao Si was painting for a long time, so he said.

"Hmm...... When His Majesty returns to Xianyang, I think it's almost done. Zhao Si nodded.

It was only an experiment before, and if it really needs to be mass-produced, it is certainly impossible to filter it with cloth, and it is impossible to continue to use firewood to boil dry water and produce salt.

In this era, cloth was quite expensive, firewood was not expensive in this era, but it was by no means cheap, and the price of salt is now high because the coastal areas with the largest salt production still use the boiling salt method instead of the drying salt method.

"Say......" Wang Li said as he moved a few times next to Zhao Si.

"Don't you remember where your home is?"

After some days of contact with Wang Li, he naturally talked about the issue of nationality, but Zhao Si still used the perfunctory past when he went to sea and fell his head in the wind and waves.

In fact, he couldn't remember anything, he didn't have any memory when he crossed over.

He couldn't even speak, he couldn't understand. As for the name, I also learned that my name was Si from other children. Because he couldn't remember his surname, and he was not used to not having a surname, Zhao Si happened to have a wooden plaque engraved with the word Zhao, and he simply called himself Zhao Si if he thought about what kind of talisman or the like.

It sounds the same as the name of Nicholas Zhao Si, and it can somewhat remind that he is a traverser.

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 get through the predicament.

From the beginning to the diagram, to the fluent local dialect at the end.

It is worth mentioning that the official dialect of Xianyang is not the same as the modern Shaanxi dialect.

The times are too far apart, and Zhao Si has just arrived to tell the truth and listen to foreign languages.

"I sent someone to inquire, but I haven't heard of a boy named Zhao Si enlisting in Xianyang." The king left his mouth and said.

Thanks to the excellent rule of the Qin Dynasty, such large-scale conscription, basically the local government has specific records and records of the names of local service personnel.

"But the list you gave found a few names, and I don't know if it's right or not." The king left his mouth and said.

Zhao Si asked Wang Li to help with the inquiry of the ashes of the deceased crew members brought back.

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

"Send it to me!" Zhao Si opened his mouth and said.

"I haven't found out yet, there may be duplicate names and so on." The king left the road.

"They themselves can't remember where they come from, and even if they have the same name, as long as they went to sea with the ship at the beginning, those who have not returned now will either stay in Fuso or die at sea. Even if it is the same name and surname, no one can tell the difference. Zhao Si said.

He wasn't trying to fool things around.

It's about going to sea, and if you don't come back, even if you stay in Fuso, it's not much different from dying for your relatives here.

Regardless of whether it has the same name and surname, send the ashes back, and both parties will have comfort.

Finally, I won't bury the ashes of those crew members who can't remember their origins casually, if they really have the same name and surname, they have the right to recognize a godfather if they are so fateful.

In this day and age, there are no cameras, and the crew members have lost even their own passes, so it is impossible to be 100% sure in this situation.

It is already the limit of this era to be able to match the name and the list of those who go to sea to serve, and the appearance of the same name can only be said to be due to fate.

This is already the end of the story.

"Then give me their relics, and I will send them." Wang Li nodded.

There are few corresponding names in Xianyang, and the three thousand boys and three thousand virgins who fishermen go to sea are all over the place, Wang Li took a few away, and there are dozens of jars left for Zhao Si.

"Thank you!" Zhao Si stood up.

In the next few days, Zhao Si was busy figuring out his mathematical formulas.

The main thing is that this thing has been useless for too long, and a lot of it has been blurred.

But after all, I learned it once, and I was engrossed in recalling, and it wasn't that I couldn't recall it, but many memories were relatively fragmentary and vague.

After Zhao Si figured it out, he was not sure whether it was right or wrong, and he had to check it several times according to the formula.

One calculation is not enough, because sometimes the wrong formula can achieve the correct result by chance.

Pythagorean theorem

triangle inequality

Formula for calculating the area of a circle

The formula for calculating the circumference of a circle

Parabolic equations

Cone volume area

Spherical volume

Zhao Si remembered a lot of things, and they were also very miscellaneous, and even some formulas were obviously correct after repeated verification, but Zhao Si still felt that what he wrote was not the same thing as what he learned at the beginning.

For the certainty, Zhao Si has marked the check mark.

Some of them still feel that they are not right after verification, and put a question mark.

With Zhao Si's current level, he will definitely not be able to reverse the principle of proving the formula right or wrong.

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 this, as for the principle or something, I can only wait for the people of this era to continue to fill in after learning.

For more than ten days in a row, Zhao Si chatted with Wang Li to see the tools used by the craftsmen, which was to recall and calculate these mathematical formulas.

After all, he learned something once, and Zhao Si's math grades were not bad at the beginning, so it was normal for him not to remember for a while, and he could always remember some of them after thinking about it for ten days.

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

Some of the more esoteric ones are not clear to remember, and some are not sure, but Zhao Si has also recorded them.

"It's over!" Zhao Si looked at the messy silk in front of him and sighed.

Mathematics is really a headache to learn, but I didn't expect that this will pass through Daqin, and I will have to be tortured again.

"It's finished?" Wang Li spoke excitedly on the side.

"I can't remember anything else." Zhao Si nodded, looking at Wang Li's happy face, a little puzzled.

"Why are you so happy?"

"If I don't do it anymore, I won't have any money......" Wang Li rolled his eyes.

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

"So expensive?" Zhao Si was a little stunned when he heard the king leave and cry.

"These days, you have enough silk to buy a big mansion in the upper part of Xianyang City!" The king departed.

Because Zhao Si needed to constantly check the trial and error, the writing on the bamboo slips was not cool enough, so he asked Wang Li and there was no more convenient writing material.

I didn't expect Zhao Si to be a strong use, I didn't feel distressed at all, this thing is a luxury, very expensive, there is no way to reimburse, it was all Wang Li who paid for Zhao Si out of his own pocket.

Zhao Si himself only knew that silk would be more expensive, but he didn't expect it to be as expensive as Wang Li said. He really didn't know much about the prices of this era, and after coming to Daqin, in addition to crossing the ocean, Zhao Si hadn't even been 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 only felt distressed.

"This thing...... Can you still sell it for washing? ”
