"What is this?" asked Andrea, chewing on dried fish. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

His Royal Highness the Prince of the Grey Keep was tossing around the novelty again, only to see him splice together a piece of copper pipe, and then let Anna melt the joints, and then wrap Zoroa in a soft layer of magical creation. At first glance, it looks like those plumbing pipes installed in the bathroom, but they are much larger, each one is close to the thickness of one's thigh, and one person can't lift it without hummingbird weight loss.

And the brass pipes were not found in one or two rooms, but ran horizontally through the whole castle and the witch's house, entering through one corner of the room, leading along the bottom of the wall to a strange metal louver, and then passing through to the next room, where it was connected to the longitudinal pipes at the end.

This huge project attracted many witches to watch, whether it was Sleepy Island or the Witch Alliance, all of whom showed great curiosity about it.

"Y'all guess?" he smiled mysteriously, "and if you're right, add an extra ice cream bread to dinner." ”

Andrea was immediately interested, ice cream bread! It was the most magical delicacy in the region, two pieces of bread baked to the outside and tender on the inside, combined with a sweet ice cream filling that had never been heard of in the Kingdom of Dawn. The first time she tasted it, she instantly fell in love with the food, and despite being repeatedly ridiculed by the ashes, she had to eat it with a red face, otherwise it would be a torment to look at it on a plate.

"Is this to put water in the room?" said Ash with a frown.

Still short-sighted, Andrea pouted in her heart, copper is not a cheap metal, since the small pipes in the bathroom can carry water, why make it so big?

However, as soon as she opened her mouth to refute recently, she would be blocked back by who said that the food was the original and the best, and this was said in front of Master Tilly, so it was really inconvenient to deceive her, so she had to act as if she hadn't heard the other party's superficial words.

"Short-sighted, how can such a large pipe be needed to connect water," someone said behind him, "Your Highness will not do such a thankless task." ”

Exactly as she thought, Andrea was in good spirits, and the one who dared to speak to the transcendent witches in such a tone was not only herself, but also Miss Nightingale of the Witch League. She looked back, and sure enough, she saw the other party looking at the ashes with disdain, and the angle of the chin was just right.

That's how aristocrats should have that expression!

Andrea secretly praised that after coming to the border town, the witch she was most affectionate to was this elusive woman. When rescuing the relic witch, the nightingale showed extraordinary skills, and he was from the same noble background as himself, and even the hair color was very close! In several sniper battles against mixed evil beasts on the city wall, the other party also recognized his ability, and also shared the dried fish with himself, quite aristocratic style.

On top of that, she also doesn't like to see the ashes either.

Although it is not known how Ash offended her when he first came to Bordertown, he ...... The enemy of her enemy is her friend, isn't it? What's more, her personality is so compatible with herself.

"As if you know the answer," Ash shrugged.

"Of course I know," Nightingale curled the corners of her mouth, "I stayed in my office while His Highness drew the blueprints, and I saw all the drawings he made. ”

"It's not fair!" muttered Mitsuki.

"She doesn't take part in the quiz," the prince's words made Nightingale's smug look stiffen, "I'll give you a hint that these pipes are just part of the system, and you might as well look elsewhere to guess the answer." ”

"Goo!" Maisie and lightning immediately flew out of the room, and the other witches were not far behind, and scattered in search of the direction of the pipe. Andrea deliberately left behind everyone, and when they left, she glanced at the nightingale and called her out the door.

"What the hell is this?" asked Andrea in a low voice, "if I get it right, I'll give you half of the bread for dinner." ”

"I don't know. Nightingale's answer made her slightly stunned.

"Didn't you say you'd seen all the drawings?"

"Yes, it's like "Foundations of Natural Science Theory", you know all the words on it, right? But can you understand what it means when it is connected together?"

"Uh-" Andrea opened her mouth, only to find that the other party had said something completely reasonable, and that the book had been turned over by herself, and it was indeed no different from the book of heaven.

"If you can understand Her Highness's intentions just by looking at the drawings, I'm afraid Anna is the only one in the League of Witches who has such abilities," Nightingale prompted, "and ask her, and she will surely tell you the answer." ”

When she left, Andrea hesitated, but finally didn't say anything to call Anna out of the room. It's not that he's reserved or embarrassed, it's ...... Awe. She had never feared the most vicious gangsters or the ruthless Inquisitors, but she felt a genuine fear of the girl, who was not yet twenty years old.

She remembers passing by the Prince's office once and hearing Anna talking to His Royal Highness, and the thought of what was going on gave her goosebumps all over her body. What high throw angle calculation, brought into the landing point parameter correction orbit, and the kinetic energy conversion in the ideal state, made her stand in place for a moment. Why is it that the other party can speak words that she doesn't understand at all so fluently, even though she is a witch? Since then, Andrea has developed a feeling of admiration for Anna, feeling that she is not the same kind of person as herself, but on the same level as Lord Tilly.

Since I can't ask the answer, I can only rely on myself. At the Prince's suggestion, Andrea probed the past room by room, which she found now finished, and the brass pipes were separated by a right-angled iron fence, as if afraid that people would touch the pipes. If it weren't for the barbarians like the ashes, it wouldn't matter if the brass pipes were touched, right? Thinking of the nightingale's remark that His Highness never does thankless things, it seems that these iron fences obviously have their own uses.

When she reached the first floor of the Witch's Building, she made a new discovery, there was an additional bungalow between the castle and the Witch's House, from which the copper pipes leading to the two buildings extended.

Inside the house was a large iron box, the bottom half of which was hollow, and a huge chimney at the top...... It looks like a stove for cooking. And she saw that there was a pipe that was connected directly to the well in the yard, which looked like a water supply device for a water tower.

Wait a minute...... Is this used to boil hot water?

But if the pipeline is used to transport hot water, there is no need to make it so big, right?

Andrea was puzzled and couldn't figure it out until the end.

Before dinner, His Royal Highness gathered all the witches into the hall and said with a smile, "From today, the castle heating system is officially activated. ”

"Heating?" Ash wondered.

"That's right, after the hot water boils in the boiler, the hot steam enters the room down the pipes, and the temperature in the room is raised through the radiator, and as long as the doors and windows are closed, the whole room can be warmed up very quickly," the prince explained. After the commissioning is completed, such heating equipment will gradually become more and more common in residential areas. ”

"Then next, tonight's ice cream bread winner, apart from Anna, Zoroa, and Hummingbird, who participated in the installation of the heating system, there is only one person who guessed correctly, and that is - Tilly!"

At dinner, Andrea stared at Mistress Tilly's delicious smile, completely forgetting her reserve as a nobleman.
