The last two boxes did not contain books.

To Liszt's surprise, one box contained all kinds of jade, and the other box contained all kinds of crystals: "Jade, crystal, the value of these two boxes will definitely not be lower than the value of Mithril ore!"

He picked up a milky jade.

The regret of the disappearance of books has been somewhat diluted.

Jade and crystal can probably be counted as types of gemstones. However, the origin of the two is completely different, jade comes from the earth, and like saltpeter and sulfur, it is a natural ore produced by the earth, while crystal comes from the dragon, which is the associated ore of the dragon to produce gemstones.

Dragons can produce gemstones, and gemstones have extraordinary magical powers.

But gem mines are scarce, and more are associated crystal mines around gem mines, with citrine around topaz and red crystal around ruby.

Crystals also contain magical powers, but the magic of crystals is relatively rare compared to gemstones.

Aristocrats liked to use crystal to carve drinking cups, and Liszt's castle had a set of such crystal goblets for entertaining dignitaries. Crystals are also commonly used to make magic lamps, which can last day and night until the magic contained in them is consumed, and there are crystal lamps in castles with names.

Crystal is also an excellent jewelry for aristocratic ladies, a crystal necklace, can add a lot of style to the ladies.

The jade from the earth, also called magic jade, is also a stone with magical power, but the magic it contains has been highly integrated with the jade itself, which is difficult to develop and utilize, and cannot make magical items.

But jade is the best food for elves.

During the Cordyceps transplant, the elves have to rely on eating jade to maintain their lives, and when contracting elven worms, they also have to use jade as bait, and make containers out of jade for elves to live in, which will increase the evolution probability of elves.

Therefore, the value of jade is not lower than that of crystal.

Open the gem space.

After putting a box of jade and a box of crystals into it, Liszt shook the bell and called out to the butler: "Mr. Carter, I have put away the treasures in the box, most of them are old and badly damaged, and only a few residues remain. You have people take them away and throw them away. ”

He rummaged through the boxes of books, and the books were all rotten, leaving no legible handwriting.

This is a disadvantage of thick skin paper and cannot be stored for too long. Liszt felt that there was no historical record of the other world, and it must have something to do with thick paper. During the production process, the thick skin paper undergoes an "acidification" process to allow the paper to be written smoothly.

However, acidic things are prone to chemical reactions and are difficult to store for too long.

That's how he understands it.

"Despite the regrets, on the whole, this shipwreck treasure has made me a windfall, which is good!" thought to Liszt.

The mood is gradually becoming more relaxed.

So for dinner, he asked the kitchen to hold a barbecue meeting.

Galtai, Marcus and others all came to participate, and they also knew that Liszt had a good harvest today, but they did not ask what the treasure was.

......

For three days.

Liszt was all concerned about the situation of nightshade.

The transplanted wild nightshade has adapted to the new soil environment and has begun to rejuvenate itself, the green leaves are shining, the flowering continues to bloom, and the fruiting continues to bear fruit. Only the nightshade, which gave birth to the elven worm, is always in a dying state, and its magic power is intermittent, and it feels like it will die at any time.

However, he didn't die, he just held on.

On the smoke mission, there is no change, which means that the task is not completed.

"The magic of the black pearl should be sufficient, I can see underneath the soil, there are signs of magic emanation...... I can't exert more strength, nightshade little worm, whether you can survive depends on your own desire to survive. ”

This is a smoke mission that can only wait - wait for the nightshade to die, the mission to fail, or the nightshade to come back to life and the mission to complete.

Liszt stood up.

Looking in the direction of the castle, a yellow-gray horse was galloping towards the castle.

"It's Marcus back. He rode back to the castle and bumped into Marcus standing at the gate, "Mr. Marcus, this trip went well?"

"All the best, my lord. Tomorrow, Brad, the crystal craftsman, will come to Flower Town with the convoy of the flower caravan to serve you for a month. ”

"Thank you, Mr. Marcus. ”

Li Ste nodded, after he obtained a large number of crystals, he came up with an idea to make a telescope - glass is the most suitable for making telescopes, but glass production is more complicated, Liszt has no ability to produce glass for the time being, so he can only use crystals to make telescopes.

Transparent white crystal, polished smooth surface, make a pair of telescopes, it is still very simple.

There are craftsmen in Coral City who specialize in making crystal ornaments, and these craftsmen may not be able to make crystal into crystal lamps, but polishing the concave and convex mirrors will definitely not make it difficult for them.

"Are the two lenses of the telescope concave or convex lenses?" Keep in mind that the monocular is composed of two lenses, which are elongated and shortened, and the distance you can see is different. Hiring a crystal craftsman for a month should make a good pair of telescopes.

Brad, the crystal craftsman.

Arrived the next day as promised.

He was a bald, middle-aged man with two big beards, and he spoke in an urn voice: "Dear Baron de la Flowertown, Brad greetings you." ”

"Brad, do you know what I hired you for?"

"Mr. Marcus said, "I'd like to make you a few crystal pieces. ”

"Yes, help me hit a batch of mirrors. Liszt handed him a few pieces of white crystals, which were the companion mines of white gemstones. As for what kind of dragon gem the white gem was, Liszt didn't know about it - there was a lot of information about dragons, but most of them were vague.

Those countries that have dragons always hide the mystery of dragon gods.

"Is this a white crystal, I can feel the magic it contains. "Brad is a freelance craftsman and a trainee knight, and he has a fighting spirit – a craftsman who makes gems and crystals must have a fighting spirit.

Liszt shook off a piece of thick paper: "I need you to make these white crystals into such mirrors, the surface should be very smooth, and the thickness should be consistent, not different thicknesses, and the shape should also be round." There are two sizes of mirrors, but the thickness can be varied. ”

The structure of a convex and concave lens is drawn on the paper.

I couldn't figure out what kind of convex and concave lenses with focal length were suitable for combining into telescopes, so Liszt simply asked the crystal craftsmen to make a few more pieces, and then combined them one by one for experiments.

"As you wish, Lord Baron. ”

"Then you will stay in Flower Town, if you can polish these mirrors in advance, you can leave early, and the salary is still a gold coin promised before. ”

Crystal craftsmen belong to the relatively high-end craftsmen, and they usually earn a good income, and it is normal to earn twenty or thirty silver coins a month. Liszt wanted to hire them for work, and he had to pay them more.

In the following time, Brad began to carefully polish the concave and convex lenses.
