Accompany Da Vinci's Super God Day

The small package sealed with coarse cloth was immediately dug out, and it was held in front of Lorenzo intact.

As soon as he lifted his fingertips, the servant next to him took out a dagger, picked up the suture thread according to the stitches, and immediately poured down the necklace like a spring, and the lord reached out to catch it.

The man looked down at the necklace and frowned slightly.

"what is this?"

This is a Cartier necklace from the 1930s.

The star-like diamonds are inlaid on the silver chain, even if held in the palm of your hand, they still shine like a crescent of moonlight.

In order to please the most unique beauty in Vienna, the arms tycoon bought countless jewels for her.

Fragmented blue diamonds are dotted in the meantime, but they are completely reduced to supporting roles.

Diamond looks like a translucent gem, but even if the angle is adjusted slightly in the sun, there will be endless brilliance refracted out.

Just one necklace is inlaid with hundreds of diamonds, which together outline interlaced curves. The hollow workmanship is extremely exquisite, without any trace of manual polishing.Huge pearls are embedded in it, making it full and lustrous against the background.

"This—" the attendants beside him were startled.

He has been with Master Lorenzo for so many years, and he has seen all kinds of expensive jewelry, but he has never seen such a strange thing.

"Perhaps, perhaps, diamonds?"

Lorenzo raised his hand and observed its light more closely: "Even the Pope's diamond doesn't look like this."

He squinted his eyes, as if he was counting something: "The reason why this gem is so dazzling is because it was cut into thirty, no, there are more facets than thirty."

This kind of gemstone is recognized as a protection against evil spirits, and only the king and the upper nobles are eligible to hold it.

But that girl not only has such a large string of diamonds, but also they are not only numerous, but they can also be cut into dozens of facets. This is definitely not a simple matter.

"Then, shall I send someone to arrest her?"

The attendant Kexima observed the expression of the lord, and continued to be cautious: "She is probably a thief, who escaped from the noble family of a nearby country."

"Don't act rashly." Lorenzo played with the necklace by the car window, and said after a long while: "If it is really a thief, you should sell it to a black market dealer as soon as you come here, and then leave here as soon as possible."

Bury it here, come back to check and continue to bury it, maybe there is something hidden.

Since he was a child, he had a lot of contacts among celebrities, and he was used to seeing all kinds of accessories on the necks and wrists of ladies, but today was the first time he encountered such things.

"Kehima, ask someone to sew it up as it is, and stuff it back in."

"Put it back? My lord?"

"Tomorrow, go and find out what other novelty jewelry is on the black market recently," Lorenzo said lightly, "She may have more than one of these things."

"Okay - yes, my lord."

When Heidi returned to the workshop, Leonardo da Vinci was concentrating on helping a guy with his woodworking work, as if he was going to make some small props for theatrical use.

He had previously received an order for a portrait of a noble lady, but now he scribbled a draft and threw it aside, not even a clear outline.

As soon as he saw his maid came back, he hurriedly threw the gadgets in his hand to his friends, and turned around to paint on the drawing board.

The friend greeted Heidi with a smile and returned to the theater, leaving only Da Vinci with his back to her to concentrate on his work.

Da Vinci actually didn't dislike someone watching the process, but he couldn't help being distracted easily.

There are so many interesting things in this world, such as bird wings, lizard tails, and human fingers, it seems that you can study anything for a whole day.

There are indeed various reasons why his paintings have been delayed again and again.

When Heidi came over again, she was holding a piece of paper on which a grid was drawn as fine as a table.

"I was just now—" Da Vinci tried to make her understand himself: "I was just doing my friend a favor."

Heidi was not in a hurry, just drew the grid and showed him the paper.

"what is this?"

"It's the month, sir." Heidi said slowly: "There are twelve months in a year, assuming we can live for 70 years, then there are 840 grids."

She looked at the brown-haired young man, and blackened a large grid with a charcoal pencil: "Sir, you are already 26 years old, so 310 two grids have disappeared."

Da Vinci was a little shocked to see her paint nearly half of the grid, and tried to stop her: "It can't be—it can't be so much?!"

"That's all."

"Did you calculate correctly? At least half of the tablet is left?!"

"No, sir." Heidi showed a rather regretful expression: "You have only so many grids left."

Going forward, when I am over 80 years old, whether I can hold a pen is a problem.

Da Vinci stared blankly at the grid for a long time, then suddenly stood up and walked out.

"Where are you going?"

"Lord's Palace!" He said without turning his head, "I'll finish that mural today!"

Heidi couldn't help laughing, and said loudly: "I made dinner and brought it to you—"

"Remember to bring orange juice!"

"it is good!"

The content of this painting is that the shepherds are paying respects to the baby Jesus in Bethlehem.

He is restrained and reserved in the choice of colors, and puts more energy into the spatial perspective of the near and far views. The baby paintings are vivid, and even the round hands are quite lifelike.

Heidi watched the mural from draft to finish with her own eyes, and would ask some questions when she handed the tools to the side.

"This little baby, do you have a reference?"

"Well, my half brother."

She froze for a moment, then politely said, "Sorry, maybe I shouldn't have asked this."

Da Vinci didn't stop moving, just glanced at her: "It's nothing."

Heidi was embarrassed to know about his family background, so she refocused on the mural.

She suddenly thought of the purple paint she saw in the pharmacy, and asked curiously, "Sir, why don't you use purple in your murals?"

Generally, nobles are very generous in their orders, and even if they need gold powder, they will send some in advance. The Medici family is a family of banks, so it is impossible to be stingy on this matter.

In the end, Da Vinci was dazzled by the bright and dark lights in different places, and his tone was quite flat.

"Because it stinks."

Smelly?

Heidi was sorting out the sundries beside her, and suddenly realized something.

Could it be that the strange smell she smelled through the glass cabinet that day really came from that paint?

"Do you know what the purple paint is made of?"

"……what?"

He turned around and looked down at her with a half-smile: "Mex."

"This kind of snail not only needs to be soaked in salt water, but also soaked in urine for a long time."

"The Romans had a large urinal, which was specially used to soak the murex for a long time. The smell was so bad that even demons would not dare to approach it."

Just listening to his words and thinking about it, I don't want to see purple anymore.

She fanned the wind, but still sighed: "It's a pity."

"What a pity?" Da Vinci frowned and repeated.

"This color is so beautiful. If it is in your hands, sir, you will definitely be able to draw more classic works." She held her chin and said, "It's really a pity."

Da Vinci's expression moved slightly, but he was too embarrassed to ask any more questions, so he just turned his head and continued to add color.

My drawing is definitely better than that of that sycophant of Keg.

Count her knowledgeable.

Old Mr. Da Vinci was quite surprised and fortunate that the eldest son handed in the draft so quickly.

He watched the child grow up, and helped wipe his butt from time to time. This time, he not only finished his mural, but even handed in the manuscript ahead of schedule—he really wanted to go to the Hundred Flowers Cathedral to sing praises.

The steward of the Medici family came to check the results, and generously gave them five gold coins, equivalent to six hundred Soldi.

This gold coin is also engraved with holy images, and the pure gold texture makes people grinning uncontrollably.

Da Vinci finally breathed a sigh of relief, and continued to draw small flags for the amphitheatre, doing all kinds of things he liked.

On the other hand, Heidi went to the pharmacy and finally got the copper ore that had been delayed for several days.

The shopkeeper's cousin was a miner, and although he didn't get a whole piece of gallstone, he got back a large piece.

Between the ores, there is an obvious thick layer of pale white minerals, with some traces of green on it, and I don't know what it is.

Although the good-tempered Mr. Arecio insisted on not asking for money, Heidi still gave him a large bottle of wine, which was considered hard work.

She wrapped it with the coarse cloth she had prepared, and returned to the workshop as if holding a large piece of bread, and began to think of ways to deal with this thing.

The reason why the copper sulfate ore will fade when taken out of the cave is because the water is evaporated and becomes anhydrous copper sulfate.

Heidi took a knife and paper, and knocked off the pale white crystal little by little.

The texture of this thing is quite brittle, and it is quite convenient to handle, just like shaving rock sugar.

Probably because of her a little loud movement, there was a knock on the door.

Da Vinci originally wanted to ask her about her preparations for Christmas next month, but when he heard the sound of thumping in the bedroom, he felt a little puzzled.

The door opened quickly, and the little maid blinked at the door and said, "Sir, do you have any orders?"

"You get out of the way."

As soon as she backed away, the stone on the table was exposed.

This thing is really big, and it may be found under the bed, and there is no need to hide it.

"This - stone?" Da Vinci asked in surprise, "What are you doing?"

Heidi glanced at the crushed powder and said with a helpless smile, "I want to help you make some paint."

It's okay to open the door, as you will need to ventilate the sulfur dioxide later.

Da Vinci quickly recognized what it was. There was also a copper mine near his hometown, Vinci Town, and he had visited it when he was a child.

"Can you, can you turn it back to blue?"

"That's what the alchemist next door taught me." Heidi made up nonsense without changing her expression, "Sir, can I borrow the small cauldron in the kitchen?"

They built a fire, sprinkled the crushed white powder into the water, and began to heat the solution in the water.

A miraculous scene happened.

The many powders that were immersed in the water just now, together with the shallow half pot of water, turned blue continuously with the increase of temperature, and translucent ice blue crystals were precipitated.

Ultramarine is as expensive as gold, and its powder produces a deep and elegant pigment, and this crucible is full of lively and light sky blue, reminiscent of a sunny day after a storm.

Da Vinci couldn't even control his expression, he covered his face and didn't speak for a long time.

"Actually——can it really be turned back? How is this done?!"

He turned to look at Heidi, happily like a child: "Will these solutions change color when you use them to paint?"

"No." Heidi controlled the temperature, and put the crucible on the stone platform next to it to let it cool down.

If it is heated too much, it will react again, turning from blue to white again.

"We have blue—and it's inexhaustible!" Da Vinci even wanted to reach out and hug his little maid. When he looked at her, his brown eyes were shining brightly from the fire: " How should I thank you?"

"Meat." Heidi said concisely, "I want to eat meat."
