North slope mine, firing room backyard.

The nightingale picked up the glass on the table and raised it above her head. The crystal clear body of the cup sparkles in the light, and there is no variegation to be seen at all.

She knew that this cup was called a crystal cup, and that the firing process and recipe had always been top secret information from the royal alchemy workshop. The value of this goblet in his hand alone is about a golden dragon. Crystal glassware with delicate silver cutlery has always been a favorite of the aristocracy and wealthy to show off their wealth.

Now, these crystal vessels brought from the palace will soon be turned into raw materials for smelting.

"Your Highness, you are not burning a cup, you are burning a golden dragon. Nightingale sighed.

"I didn't have time to figure out how to burn sand into colorless glass, so I had to make do with it this way. Roland threw an elaborate crystal jug into Anna's black fire furnace - the nightingale remembered that the prince had used it to serve ale and fill the sisters with cups at the afternoon tea in the castle garden and at the Festivities of the Demon Moon.

At a steady high temperature, the pot quickly softens and then dissolves into a puddle of sticky paste.

"With sand...... "Is it the same substance?" asked Anna.

"Well, the main ingredients are almost the same, but the sand contains a lot of impurities, and most of the burned glass is brown and green, which cannot meet the requirements of use. ”

"So, glass is pure sand?"

Roland smiled, "Think so. When I write this part of the knowledge into a book, you will understand how those little balls are made up of matter. ”

I won't understand anyway...... The nightingale pouted, besides, the different colors of glass do not affect its container function, anyway, you don't use it as a water cup, why do you have to use a transparent crystal cup to fire. She walked over to Anna and looked at the glassware that had been recast.

Although they still look colorless and transparent, their appearance is far from the previous crystal cup.

Some look like tubes, with a rounded base that is thin and long. Some of them are like bottles, as big as a kettle underneath, and only a thumb-thick mouth on the top.

The strangest thing is that a tube that has been bent into the shape of a horseshoe, with no closures on either side, and it is simply impossible to make a container.

"What are you going to do with these crystal glassware?" asked Nightingale.

"It's not for me, it's for the alchemists of the border towns in the future," Roland stirred the slime in the black fire with a glass rod, "They can use these utensils to extract some acids and alkalis to produce the chemicals I need for new weapons." ”

The nightingale blinked, and found that she couldn't understand what His Highness was saying at all, and this feeling made her a little depressed. But if she wanted to ask one by one, it was too ignorant, and she didn't want to show this side in front of Anna, so she had to focus on the only noun she could understand.

"Where are the alchemists in the town? Even if it's the Changge Fortress, there is no alchemy workshop. You can only find alchemists in Chishui City, and I've heard that their salaries are higher than those of lord ministers, so it's hard to recruit them with the golden dragon alone. ”

"You know a lot," Roland replied with a smile, "and that's true. The people I sent are already on their way to Chishui City, and they will get the news in about two weeks. But I'm not recruiting them with golden dragons, but some alchemical secrets. I'm not sure if I can recruit them, so I'll have to try. ”

The first half of the Prince's praise dispelled the nightingale's suffocation, and she returned to the middle of the courtyard contentedly, picked up a ball of pastries on the round table and stuffed it into her mouth.

Since Roland changed the main experimental site from the castle backyard to the firing room on the north slope of the mountain, afternoon tea has also been moved.

On the round table are all court snacks specially prepared by His Royal Highness the Prince.

For example, this steamed bun has a skin made from wheat flour, and I don't know how it has been processed, and it is extremely soft. It is also wrapped in a mass of minced meat, chopped into a foam, containing the juice...... It's not like bacon, which is hard and hard to swallow. As soon as you bite into it, the minced meat will melt into the gravy.

The nightingale put her fingers in her mouth and sucked them one by one, and sat back on the chaise longue, feeling sleepy.

Seems to be getting lazier lately?

The afternoon sun sprinkled on her body, and the warmth like water slowly surrounded her. The rustle of the leaves in the spring breeze made her feel peaceful. She took off her shoes, rolled up her legs, and lay on her side.

From this vantage point, you can see the side door of the backyard leading to the gunpowder room, with a gauze curtain hanging from the doorway, presumably a means used by His Highness to prevent himself from sneaking in. Thinking of this, Nightingale felt a little funny, whether it was the partition wall of the courtyard or the outer wall of the production room, it was a flat ground that she could walk freely on. She had also entered a mysterious room, and sat by while His Highness explained how to make it, but she did not take the finished gunpowder.

And the other party thought that he was doing something unknowingly, completely unaware that he was the one who was kept in the dark.

Nightingale shifted her head and looked at Anna.

She was holding a freshly fired tumbler, talking to His Highness, looking serious and focused.

For this talented woman from a civilian family, Nightingale was full of admiration.

The Mutual Aid sisters were able to escape their fate from the torment of the Witch Rebellion, in large part because of Anna, who would not have been able to turn the corner if she hadn't changed the prince's mind about witches.

If His Highness would really marry a witch as his wife, then Anna was pretty much the only person she could think of.

Despite the glimmer of anticipation in her heart, Nightingale chose to bury it deep in her heart. Most of the time, just being around Her Highness was satisfying.

She closed her eyes, and an image involuntarily came to her mind.

Roland ascended the throne in the main hall of the palace, wearing a golden crown and holding a jeweled scepter, and walked to the castle terrace to receive the admiration and cheers of the people.

Beside him, the woman in a white satin dress walking hand in hand was none other than Anna. She also wore a glittering crown on her head, covered with a veil, and smiled and waved to the people.

Lightning swirled in the air, sprinkling bright red rose petals, and in the distance, a melodious bell rang from the bell tower of the royal capital.

He and the other sisters stood aside and applauded and sent their blessings.

Increasing drowsiness spread throughout the body, and consciousness gradually became hazy.

Roland turned around, lifted the woman's veil, and lowered his head to kiss her on the lips.

The final scene became very blurry, and as the veil fell to the ground, the nightingale saw the woman with her eyes closed...... But it was herself.

The corners of her mouth curled and fell asleep. (To be continued.) )
