Huang Chengyan held the glass and said, "This is probably a crystal cup?"

Then he held the mirror and asked, "This, what is this? Is it a crystal-mirror?"

Lu Bu laughed and said, "Wrong, this is a glass cup, this is a glass mirror!"

Huang Chengyan asked curiously: "Is this the glass you want to make? The cost must be very high, it must be difficult to make, right?"

Lu Bu couldn't help but laugh and said, "Although it's a bit difficult to make, the cost is actually very low. You may never think that the raw materials for making glass are just river sand!"

Huang Chengyan said in disbelief: "This, how is this possible? How can this be made of such a good cup with river sand? If this is really the case, it can be said that it has turned into gold! By the way, Fengxian, are the glass cups and mirrors in your hand made by you yourself?"

Glass and mirrors? Of course not, I took it back from Hyundai.

Originally, Lu Bu’s purpose was to be a sample, and after he arrived, he wanted to give it to Diao Chan.

Then I thought about it and there was Zhang Ning.

If it is given to Diao Chan but not to Zhang Ning, it would be more favorable than to the other. Therefore, Lu Bu did not give it to anyone.

Lu Bu couldn't help but smile and said, "No, these two things were found in Zhang Jiao's room."

Huang Chengyan couldn't help but ask in confusion: "Even if that's the case, why didn't I find the craftsmanship of making glass in the book you gave me?"

Lu Bu smiled and said, "I forgot to write it down at that time, and I just remembered it now."

After hearing Lu Bu's words, Huang Chengyan couldn't help but curl his lips. Huang Chengyan no longer believed Lu Bu's words now.

If the glass cup and mirror were found in Zhang Jiaode's room, there is also a record of how to make glass in Taiping Tianshu.

So why didn’t Zhang Jiao make glasses and mirrors?

If Zhang Jiao had made these two things, how much money would he make?

The price of this glass and mirror is probably equivalent to gold, right?

If Zhang Jiao had used these two things to make money and used steelmaking to smelter weapons, how could the Yellow Turban Rebellion be suppressed so quickly?

There must be some unknown secrets here.

However, since Lu Bu didn't say it, Huang Chengyan was too lazy to reveal it. For Huang Chengyan, it was enough to have new creations and inventions.

After Lu Bu's explanation and Huang Chengyan's actual glass has already attracted Huang Chengyan's curiosity.

Huang Chengyan couldn't help asking Lu Bu for the process of making glass.

Lu Bu smiled and handed over all the requirements for making glass to Huang Chengyan.

And sent soldiers to help Huang Chengyan.

The glass part can be made temporarily to Huang Chengyan.

When firing the cement, Lu Bu asked Xun Yu to recommend someone to come and take charge.

However, during the production process, Lu Bu must be given guidance.

The easiest thing is of course to make tables, chairs and benches.

In Lu Bu's opinion, this is also the least profitable deal.

Because in the late Eastern Han Dynasty, although tables, chairs and benches were not popular, this was too simple and had little technical content.

Those carpenters probably can create them in a few glances.

Of course, what Lu Bu thought of was to see the best in painting.

Lu Bu can make many colors of paint, and can also make the paint brighter.

As long as the formula is controlled well, Lu Bu believes that no one can imitate this within three to five years or even ten to eight years.

And ten or eight years later, even if the formula is leaked, it doesn't matter much.

By then, Lu Bu probably wouldn't need to use this to make money.

...

Three days later, the first batch of salt in the salt drying field was finally released.

At the same time, Zhen Yi rushed back from Luoyang.

Seeing Zhen Yi's uncontrollable smile on his face, Lu Bu knew that the first shot in paper sales was good.

Lu Bu asked with a smile: "Brother Zhen, how is the sales of paper?"

Zhen Yi laughed and said, "Fengxian, you don't know. This time the paper was sold in Luoyang, and it was like snatching it crazy! I took three cars of paper over there, which was not enough to sell!"

"This is just a place in Luoyang. What if it is sold nationwide? By the way, you have to accelerate production here! Otherwise, the output will not be available at all!"

Lu Bu smiled slightly and said, "Brother Zhen, don't worry, as long as you can eat, there will definitely be no problem with the yield."

In fact, when it comes to paper sales, Lu Bu thinks the output should not be particularly outrageous.

Although the quality of the paper is very good, where is the price?

If it can be sold well in Luoyang City, it may not be so popular if it is placed in other small cities.

After all, Luoyang is the capital of the Eastern Han Dynasty, and there are many wealthy families. How can other small cities compare with Luoyang?

Lu Bu said to Zhen Yi: "Brother Zhen, it's a coincidence that the first batch of salt in the salt drying field is drying out. Why don't we go and have a look?"

Zhen Yi nodded quickly and said, "Okay, OK, that's a coincidence. Let's see how the salt is exposed!"

After saying that, under the leadership of Lu Bu, the two of them took a car to the salt drying field.

Soon we arrived at the salt drying ground. When Zhen Yi saw a pile of snow-white fine salt piled on the tarpaulin, he couldn't help but be shocked!

"This, can you spread so much salt at once?"

Before this, the Eastern Han Dynasty used the salt boiling method, which was shorter than the salt drying method, but the yield was much lower than the salt drying method.

The labor required is also much higher than the salt drying method.

How much fine salt does this pile of people need?

If it can be sold, how much money can it be sold? Just thinking about it makes people extremely excited!

By the way, the salt is thinner, and I don’t know how it tastes.

Zhen Yi stretched out his finger, dipped it in a little bit of salt and put it in his mouth to taste it, and found that there was a slightly bitter taste inside.

It is a little worse than the fine salt that Lu Bu took out for the first time, but it is much better than the coarse salt flavor that is popular on the market now.

This is enough, with this taste, you can definitely sell it at a good price!

While happy, Zhen Yi suddenly remembered the price and asked carefully: "Fengxian, I wonder what the price of this fine salt is?"

If it is too expensive, Zhen Yi will not make much money.

Lu Bu smiled and said, "Brother Zhen, I will give you the price of this fine salt once it costs 500 yuan. What do you think?"

When Zhen Yi heard the price given by Lu Bu, he couldn't help but be overjoyed: "Fengxian, open-minded! It's so loyal!"

It has to be said that the price given by Lu Bu is much lower than Zhen Yi expected.

You know, the price of coarse salt sold outside now is almost the same.

If Zhen Yi sells it to the outside world now, it will have at least twice the gross profit!

You know, salt is a consumable, and it is a monopoly business. The double gross profit is enough to make the Zhen family the richest man in the entire Han Dynasty.

However, Lu Bu said next: "Brother Zhen, but I will give you the exclusive agency rights of salt for up to five years!"
Chapter completed!
