North slope mine, fired room backyard.

Nightingale picked up the glass of wine placed on the table and raised it over her head. The crystal clear glass was shining in the light, and there was no trace of variegation.

She knew that this kind of cup was called a crystal cup, and the firing process and formula have always been the top secret information of the royal alchemy workshop. The goblet in her hand alone is worth about a golden dragon. Crystal glassware and exquisite silver tableware have always been the favorites used by the great nobles and wealthy businessmen to show off their financial resources.

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

"Your Highness, what you burn is not a cup, but a golden dragon." Nightingale sighed.

"I didn't have time to study how to burn the sand into colorless glass, so I had to do it this way first." Roland threw a beautiful crystal pot into the furnace made of Anna's black fire-Nightinging still remembers that the prince used it to serve ale and filled the sisters with cups at the afternoon tea and the Demon Moon celebration banquet in the Castle Garden. He couldn't help but feel a pity.

At a stable high temperature, the pot quickly softened and then turned into a pool of viscous paste.

"Burn glass with sand?" Anna asked, "are they the same substance?"

"Well, the main ingredients are almost the same, but the sand contains a lot of impurities. Most of the burned glasses are brown and green, which cannot meet the requirements for use."

"So, glass is pure sand?"

Roland smiled, "You can think so. When I write this part of the knowledge into a book, you will understand how those small balls form matter."

Anyway, I won't understand... Nightingale curled her lips. Besides, the glass of different colors does not affect its container function. Anyway, you are not using it as a water cup, so why do you have to use a transparent crystal cup to burn it. She walked to Anna and looked at the glassware that had been remolded.

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

Some look like tubes, with round bottoms, thin and long. Some look like bottles, as big as kettles on the bottom, with only a piece of the mouth of the bottle as thick as a thumb on it.

The strangest thing is a kind of tube that is bent into the shape of a horseshoe, with no sealing on both sides, which is simply impossible to make a container.

"What are you going to do with these crystal glassware?" Nightingale couldn't help asking.

"It's not for me, it's for the alchemists in Border Town in the future," Roland stirred the mucus from the black fire with a glass rod. "They can use these vessels to extract some acids and alkalis to produce the chemicals I need for new weapons."

Acid, alkali, chemicals, Nightingale blinked and found that she could not understand what His Highness was saying. This feeling made her feel a little depressed. But if she wanted to ask one by one, she seemed too ignorant. She didn't want to expose this side in front of Anna, so she had to focus on the only noun that she could understand.

"Where did the alchemist come from in the town? Even in Changge Fortress, there is no alchemist workshop. You can only find alchemists in Chishui City. And I heard that their salary is higher than that of the lord and ministers, so it is difficult to recruit them by Golden Dragon alone."

"You know a lot," Roland responded with a smile, "It's true. The people I sent are already on the way to Chishui City, and I will get news in about two weeks. But I am not recruiting them with the Golden Dragon, but some secrets in alchemy. As for whether I can recruit them, I'm not sure if I can, so I have to try it."

The first half of the praise from His Highness of the Prince immediately dispelled the nightingale's depression. She returned to the center of the yard with satisfaction, pinched a ball of pastry placed on the round table and stuffed it into her mouth.

Since Roland changed the main experimental site from the castle backyard to the North Slope Mountain fired room, afternoon tea has also been moved over.

The round table is filled with palace snacks specially made by His Highness the Prince.

For example, this dessert, called bun, has a rind made of wheat flour. I don’t know how to process it. It is extremely soft and glutinous. It is also wrapped in a ball of meat filling, chopped into crumbs, containing juice... It is not as hard and difficult to swallow like bacon. Just bite it in one bite, the minced meat will be integrated with the gravy.

Nightingale put her fingers into her mouth and sucked them one by one, leaning against the recliner, feeling a little sleepy in her heart.

It seems that I have become lazy lately?

The afternoon sun shone on her body, and the warmth like water slowly surrounded her. The rustling sound of the spring breeze blowing the leaves made her heart extremely quiet. She took off her shoes, curled her legs, and lay down on her side.

From this perspective, you can see the side door leading to the gunpowder production room in the backyard. There was a gauze curtain hanging at the door, which was probably a means used by His Highness to prevent him from sneaking in. Thinking of this, Nightingale felt a little funny. Whether it was the partition walls of the yard or the exterior walls of the production room, she was a flat ground where she could walk freely. She had also entered a mysterious room and was quietly listening when His Highness talked about the production method, but she did not take away the finished gunpowder product.

But the other party thought he was doing something without realizing it, and he had no idea that he was the one who was kept in the dark.

Nightingale moved her head and looked at Anna.

She was holding a freshly burned flat cup and talking to His Highness something, looking serious and focused.

Nightingale was full of admiration for this woman who came from a civilian family but was very talented.

The sisters of the Co-Aid Association can escape the fate of displacedness and be freed from the torture of magic backlash, largely because Anna - if she hadn't changed the prince's view of the witch, any subsequent twists would have happened.

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

Although she had a little expectation in her heart, the Nightingale chose to bury it deeply in her heart. Most of the time, just staying by her highness would satisfy her.

She closed her eyes and a picture appeared in her mind involuntarily.

Roland ascended the throne as king in the palace hall. He wore a golden crown and held a jewel scepter, and walked towards the castle terrace, receiving the respect and cheers of the people.

Aside him, the woman walking in her hands in a long white satin dress was Anna. She also wore a golden back crown on her head, covered with a veil, and waved to the people with a smile.

Lightning circled in the air, sprinkling bright red rose petals. In the distance, the melodious bell ringing came from the bell tower of the capital.

He stood aside with other sisters, applauding and sending blessings.

The increasingly intense sleepiness traveled throughout the body, and the consciousness gradually became hazy.

Roland turned around, unveiled the woman's veil, lowered her head and kissed her lips.

The final scene became very blurred. As the veil fell to the ground, the nightingale saw the woman with her eyes closed... it was herself.

She raised the corners of her mouth and fell asleep.
