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 and crystal, the value of these two boxes is definitely not lower than the value of mithril ore!"
He picked up a milky white jade.
The regret of the disappearance of the books was somewhat diluted.
Jade and crystal could be regarded as types of gems. But the origins of the two were completely different. Jade came from the earth, like saltpeter and sulfur, which were naturally produced by the earth. Crystal, on the other hand, came from dragons, which were associated with the production of gems by dragons.
Dragons could produce gems, which had extraordinary magic power.
But gem mines were rare, and more often crystal mines were associated with gem mines. Topaz was around topaz, and ruby was around ruby.
Crystals also contained magic power, but compared to gems, crystal power was less.
Aristocrats liked to use crystal carved drinking cups. In Liszt's castle, there was a set of such crystal goblets used to entertain distinguished guests. Crystals were also commonly used to make magic lamps, which could be lit day and night until the magic power contained in them was exhausted. Every castle with a name had a crystal lamp.
Crystals were also excellent accessories for aristocratic ladies. A crystal necklace could add a lot of elegance to a lady.
Jade originating from the earth, also called magic jade, was also a stone with magic power. But the magic power contained in it had been highly integrated with the jade itself, making it difficult to develop and use, and unable to make magic items.
But jade was the best food for sprites.
During the transplanting of worm stalks, sprites had to rely on jade to maintain their lives; when contracting sprite worms, jade was also used as bait; and jade was used to make containers for sprites to live in, which would increase the probability of sprites' evolution.
Therefore, the value of jade was not lower than that of crystal.
Liszt opened the gem space.
After putting a box of jade and a box of crystal inside, Liszt shook the bell and called the butler: "Mr. Carter, I have put away the treasures in the boxes. Most of them have been severely damaged over the years, leaving only a few scraps. Have someone move them away and throw them away. "
He carefully rummaged through the boxes of books. The books were all rotten, leaving no recognizable writing.
This was a drawback of thick bast paper, which could not be stored for too long. Liszt felt that the lack of historical records in this world must have something to do with the thick bast paper. During the manufacturing process, the thick bast paper would undergo an 'acidification' process so that it could be written on smoothly.
However, things that were slightly acidic were prone to chemical reactions and were difficult to preserve for too long.
That was how he understood it.
"Although there are some regrets, overall, the treasures from the shipwreck have made me a windfall. Very good!" Liszt thought to himself.
His mood gradually became better.
Therefore, he asked the kitchen to hold a barbecue for the banquet.
Gort, Markus, and the others had also come to participate. They also knew that Liszt had obtained a bountiful harvest today, but they rationally did not ask what the treasures were.
…
For three consecutive days.
Liszt was paying close attention to Nightshade's condition.
The transplanted Black Nightshade had already adapted to the new soil and environment and was beginning to regain its vitality. The green leaves were full of vigor, those that should be blooming continued to bloom, and those that should be bearing fruit continued to bear fruit. Only the black nightshade, which gave birth to the sprite worm, remained in a dying state, its magic power intermittently giving the impression that it could die at any time.
However, it did not die, and was just persevering.
There was no change in the smoke mission, which meant that the mission had not been completed.
"The black pearl's magic power should be sufficient. I can see signs of magic power emanating from under the soil … I can't use any more strength. Black nightshade, little bug, whether or not you can survive depends on your desire to live."
For this smoke mission, he could only wait for Nightshade to die, the mission would fail, or for Nightshade to come back to life, the mission would be completed.
Liszt stood up.
He looked in the direction of the castle, where a yellow-gray horse was galloping towards the castle.
"Markus is back." He mounted Blackdragon and returned to the castle, just in time to bump into Markus, who was standing at the gate. "Teacher Markus, did the trip go smoothly?"
"Everything went smoothly, Sir. Tomorrow, the crystal craftsman Brad will follow the Flower Caravan's transport team to the Flower Town to serve you for a month. "
"It's been hard on you, Teacher Markus."
Liszt nodded. After obtaining a large number of crystals, he came up with the idea of making a telescope. Glass was the most suitable material for making telescopes, but glass production was relatively complicated. For the time being, Liszt did not have the ability to produce glass, so he could only use crystals to make binoculars.
It was very simple to make a pair of telescopes out of transparent white crystal.
The Coral City had craftsmen who specialized in making crystal ornaments. These craftsmen might not be able to make crystal lamps, but it was absolutely not a problem for them to polish concave and convex mirrors.
"Are the two lenses of a telescope concave or convex?" There were some physics that Liszt had forgotten. He remembered that a monocular consisted of two lenses, which could be lengthened and shortened to different distances. By hiring a crystal craftsman for a month, he should be able to make a good pair of telescopes.
The crystal craftsman Brad.
He arrived the next day as scheduled.
He was a bald middle-aged man with a thick beard. He spoke in a low, muffled voice: "Respected Baron of the Flower Town, Brad sends his regards."
"Brad, do you know why I hired you?"
"Mr. Markus said that you want me to make a few crystal products for you."
"Yes, help me make a batch of mirrors." Liszt handed him a few pieces of white crystal. White crystal was a mineral associated with white gemstones. As for what kind of dragon produced white gemstones, Liszt did not know. There was a lot of information about dragons, but most of it was vague.
Those countries with dragons would always hide their dragons mysteriously.
"Is this white crystal? I can feel the magic power contained in it." Brad was a freelance craftsman, as well as a Trainee Knight. He had qi. Craftsmen who made gems and crystals must have qi.
Liszt shook out a piece of thick bast paper: "I need you to make these pieces of white crystal into mirrors. The surface must be very smooth, the thickness must be uniform, and the shape must be circular. There are two sizes of mirrors, but the thickness can vary. "
The structure of convex and concave lenses was drawn on the paper.
Liszt could not figure out which focal length of the convex and concave lenses were suitable to be combined into telescopes. He simply had the crystal craftsman make a few more pieces, and when the time came, he could combine them one by one to experiment.
"As you wish, Sir Baron."
"Then you will stay in the Flower Town. If you can finish grinding the mirrors ahead of time, you can leave ahead of time. The salary will still be the one gold coin promised before."
Crystal craftsmen were relatively high-end craftsmen and usually had a good income. It was normal for them to earn twenty to thirty silver coins a month. If Liszt wanted to hire them to work, he had to come up with a higher salary.
