"Humph! As long as we go, whether there is a Qianlong Dynasty in the Qing Dynasty or not, there are still two things to say! ”

Ren Ke took a big bite of lobster meat and said coldly beside him.

However, Zhu Beiguo did not take over Ke's words, he just continued to say his:

"I estimate that if the time traveled earlier, it may be the Shunzhi Dynasty, and at the latest it should be the early period of the Kangxi Dynasty, when glassware and glass mirrors were very valuable in that Eastern Continent."

"I've heard that ordinary glass cups are worth a lot!"

"The key is transparency."

"Actually, it's potash and lead glass that is worth a lot of money, because of its high transparency, hey! If you dare to say that you can't make transparent glass, I'll change a batch and not cross with you!"

"Oops! Don't worry, we can't figure it out?!"

"Brother Zhu, how much is it worth?"

"It depends on the size, right?"

"It also depends on the ...... of transparency"

"Please be quiet, for what you said reminded me of an important matter."

So Zhu Beiguo raised his voice and continued:

"I can't say exactly what the market price is for glasses and mirrors yet, but I have some indirect references.

The value of the glass cup in the palace during the Qianlong period I just mentioned is said to be worth 100 gold, note that the gold mentioned here is actually silver!

However, I still think it is a bit exaggerated, or rather, the royal procurement has taken kickbacks......

Don't laugh, there's a good chance of taking rebates! Anyway, those princes are basically blind to the market situation in the south of Xinjiang, and this group of people has no understanding of the outside world at all, and of course they don't bother to understand.

It is precisely because of this that it is estimated that those nobles have been wronged. Of course, rest assured, in any case, glassware was certainly worth a lot of money in its time.

I have looked up some valuable historical materials in the computer library, especially the trade accounts of the Dutch East India Company, which contain a large amount of information on market prices.

If I'm not mistaken, it seems that in the mid-to-late eighteenth century, high-grade glass cups with a diameter of three to five inches, that is, relatively transparent glassware, were sold from Batavia to the compradors of the Thirteen Lines in Guangzhou, and the wholesale unit price was about fifteen taels of silver.

Of course, then again, no matter how much that thing is doubled, it seems that the goods of ten taels of silver should not be worth one hundred taels of silver, right? So I guess the housekeepers ate the kickback.

Okay, let's not talk about this, anyway, we are going to travel back in time to the seventeenth century, when the glass industry in Europe was still basically monopolized by the Venetians and the French, unlike the Qianlong period, Europe was already on the eve of the industrial revolution.

Therefore, there is no doubt that the price of glassware in the seventeenth century was somewhat higher than in the eighteenth century.

The conclusion from this is that transparent glassware is indeed very valuable, and mirrors are indeed very valuable, and we must give priority to the development of these glass products. ”

After Zhu Beiguo finished talking about the glass, he saw that everyone was nodding frequently and listening carefully, knowing that everyone basically understood, so he began to change the topic:

"So, now on to the second industrial project: the history of sugar.

White sugar, unlike glass, was a popular daily consumable, but in the seventeenth century, it was also an expensive daily consumable.

According to the incomplete customs records of the Ming Dynasty, the Hongmao Yangyi ----here mainly refers to Portuguese and Dutch merchants who used to buy locally produced red brick sugar in Macao, Guangzhou, Chaoshan and the coastal areas of Fujian, Penghu and Taiwan.

The purchase price is about four to five taels of silver, but the purchase price rises sharply from time to time, mainly because the local sugarcane production is affected by weather, pests and diseases, and even war, and the output is very unstable.

According to historical data, in some scarce years, a load of red brick candy can even be sold for ten taels of silver! Note that I'm talking about red brick sugar, and a small amount of white sugar is just a by-product of red brick sugar and should therefore be more expensive.

At that time, whether it was brown sugar or white sugar, it was all about trading, but how much was this burden? There are a lot of sayings now, and it's not very clear, anyway, we'll know after we cross.

However, according to the research of some historical authorities, a load at that time, converted into our current weight unit, should be about 70 to 75 kilograms, probably, this point is basically certain.

According to the trade records of the Dutch East India Company, these maritime merchants sold red brick sugar to Southeast Asia, and the bulk wholesale price was an average of 15 taels of silver, while white sugar was even more expensive, according to records, according to different quality, the wholesale price of white sugar should be more than five to six times that of red brick sugar!

Guys, that's a lot of money, isn't it?

Of course, if a large amount of sugar is suddenly put into the market, this price will definitely not be maintained, after all, scarcity is expensive.

However, even if the price is reduced, white sugar is not cheaper, because in that era, white sugar did not form a large-scale, specialized production, and the demand for white sugar is very large, you can check the history of white sugar marketing around the world, you will find that the human demand for this kind of consumables is simply a bottomless pit! Therefore, even if the output of this product has increased because of our appearance, after all, the market capacity is too large, and no matter how we produce, it will be very limited for a while.

Therefore, in the long run, the added value of white sugar can still maintain a fairly high position.

Rest assured, even if we were to produce sugar in large quantities in the future, it would not be enough to fully meet the needs of the people of the world in the seventeenth century for a long period of time, and there is no doubt that we could have made great profits from the sugar trade for a long period of time.

Especially if we can sell these products to the north of the continent, North Korea and Japan, where there is more demand, the selling price will be even higher! ”

At this time, everyone listened with relish, and there were constantly people commenting.

"Looks like Nicole was right to suggest that we start by planting sugar cane and beets......"

"So it makes sense that Anna gave us the seeds for these two crops."

"Yes, the climate of our island is also suitable for these two things, the water and temperature are enough, after all, this is a tropical climate."

"In addition, there is one more thing I want to reveal to you......

Zhu Beiguo paused when he said this, waiting for everyone to calm down.

"What's the matter?"

"Brother Zhu, what's new?"

"That's right, the reason why Nicole and Anna's advice to us is so specific and pertinent is because the two of them once traveled to that plane in advance to call us the front station!"

Zhu Beiguo suddenly lowered his voice and said.

"! No way? ”

"Have the two been there? No, doesn't it mean that the current technology can only be one-way? ”

"yes, is there a round-trip ticket?"

"It's not very clear about the specifics, this is what Anna told us, and there were only a few of us in the Red House at the time."

Zhu Beiguo responded.

"So, can we come back?"

"It works theoretically, but it doesn't work at all."

"Why, Brother Zhu?"

"Because of the time error!"

"Error?"

"Yes, error, Anna told me for most of the day what is the theory of light quantum, what photon instability, what multiple quantum entanglement produces the shift of photon transmission information that causes the random strain of coordinates, etc......

Ay! Anyway, I didn't understand a word, but the conclusion did: for intelligent beings carrying a large amount of cosmic information---- here refers to people, the first round-trip crossing of a specific space-time, its one-way error is less than one second, and the error when returning expands to one hour, but if the second crossing of this space-time is carried out, the one-way error may swing from one second to fifty years, and if you have to return, the error will expand to about a thousand years! And the third time you cross the same place, the error may increase dramatically to more than 3,000 years, and by analogy, you will understand what the so-called error of the round-trip crossing is. ”

"Oh! Since Nicole says that our time travel error is between one second and fifty years, it is clear that we are traveling for the second time. ”

Someone in the crowd suddenly realized.

"Yes, if you count from the first time Nicole and Anna traveled to that plane, to the time we were teleported, the error could have been fifty years, of course this is the maximum, maybe only one second, maybe twenty years, in short, it's up to fate.

Therefore, when we want to see Nicole go back to the time and space we traveled through, and pick us up, that error will be about a thousand years old, so the chance that we can reunite with this era in the old world on the timeline and go back to the original era is very, very low. ”
