The day before Christmas, Ryan and Hermione spent the day on the spaceship placing a batch of observation props in seven previously selected locations to collect data. Until the sun begins to set in the west, and the sunlight turns everything on the earth orange-red. Ryan and the two of them finally dragged their tired bodies back to Hogsmeade.

"Just go and retrieve those items the next morning. After stepping through the thick snow into the town gates and into the streets, Ryan said to Hermione, "Because we're going to analyze the different ways in which places flow at different times of the day. This data is then analyzed to select the most suitable location, and the cultivation of different magical plants is arranged according to the flow of magic on the selected location. ”

"After a whole day of surveying, I could feel that the work was a bit complicated. Hermione pressed her hand on her waist, which was a little sore from the placement of the magic equipment, and said, "By the way, how many things have you stored." After opening the space door just now, I saw that the materials for your construction of the three manors were stored in a warehouse. And there are nearly a hundred warehouses in that place. ”

"Well, that's something that's stockpiled for the outbreak of a major war or disaster in several worlds. I have a total of three similar warehouse groups in different worlds, and the warehouse group in that apocalyptic world is just one of them. Ryan explained. "The materials in each warehouse group can sustain the lives of 100,000 people for three months, in addition to various magical raw materials that can sustain the normal situation of 3,000 ordinary wizards in the second half of the year. ”

"Is this the modern national reserve?" Hermione muttered. "No wonder you didn't hesitate to destroy the important production institutions of the British wizarding world, because you were confident that you would be able to fill the gaps. ”

"Yes," Ryan nodded earnestly. "Most of the Weasley Joke Shop products have been produced from these reserves lately, but I think it will be possible to localize the resources soon after these plantations are established. ”

"And what about the demand for magic ores?" Hermione asked, "Before we found the mines, could this gap be made up by similar ores you got from other worlds?"

"Don't forget the trade with the Celestial Empire and the underground trade with Europe," Ryan said, tilting his head slightly closer to Hermione, "The Hogsmeade Ministry of Magic was not idle when we fought before, and they have managed to recapture more than 60% of the overseas trade channels before the outbreak of the war. That's enough for us, after all, the UK wasn't a major producer of magical minerals before, and these things were mainly imported. ”

Hermione nodded after listening to Ryan's explanation, as an owl flew towards them, dropping a letter as it flew over their heads.

"It's Christmas Eve tonight, who will write to us at this time?" Hermione picked up the letter after checking the letter on the ground for a moment. "Uh-this is an anonymous letter. ”

"Anonymous letter?" Ryan was also intrigued, wondering why anyone would go to such lengths to send him such a thing.

You know, in the current situation where Hogsmeade is on alert, this kind of letter cannot be mailed in from outside the town with ordinary owls, and the only way is to release owls in Hogsmeade. Most of the people who were able to mail anonymous letters weren't friendly people, and Ryan couldn't figure out how anyone would spend a lot of energy sneaking into town just to send a letter.

"There was only one photo in the envelope. Hermione had already checked the envelope by this time, and after a careful examination of the inside and out, she only took out a photograph from inside, and on the back of the photo was written in purple ink the address of the newly built area of Hogsmeade.

"It's weird in the picture—" Hermione said as she looked at the photo in the last rays of the sun before it went down, and handed it to Ryan. "It looks like a tall glass for drinking wine, but it's a little short. ”

Ryan took the photo and looked at it carefully, and found that the photo was a bit old. But upon closer inspection, Ryan still realized that it was not a goblet, but a strange crucible with one leg. The cauldron was sealed in a transparent substance, and the entire transparent substance was placed on a stone platform.

It may be that the person taking the picture is some distance away from the stone platform, so the stone platform and everything on the stone platform look small and a little blurry. That's why Hermione thought of it as a glass.

"So let's go to the address behind the photo first. Ryan was intrigued by the picture, and he suggested, "Anyway, there's still a little time before dinner, and since this place is all in Hogsmeade, there shouldn't be any great danger." ”

"You're right. Hermione thought for a moment and said, "If I'm not mistaken, this place isn't too far from the Weasleys' temporary residence, we can take a look first." ”

After walking for three or four minutes along the main road in town, they turned a corner on the path that led to the Pig's Head Bar. Soon, they were in front of the townhouse at their destination. It was already dark by this time, but the candles hanging from the trees to celebrate Christmas and the street lamps on the side of the road illuminated everything clearly.

"I'll take a look, 7A South. Ryan muttered quietly as he looked at the door number, and soon they came to the gate of 7A South District. It is a standard house in the new-build area of Hogsmeade, with a small red brick two-story building with a pointed black roof and small windows that open into the roof to ventilate the attic.

"There didn't seem to be anyone in the room. Hermione said, glancing at the house through the wrought iron door in the courtyard. This is a very obvious thing, because it is Christmas Eve, and the people who live in Hogsmeade use mistletoe to decorate the house with mistletoe branches and lights in the morning. The house in front of him was dark, with no lights at all, and there was no decoration outside.

Of course, there is nothing surprising about this. After all, when the house was built in the first place, it was better to have more than less, so it is true that there are many temporary houses that are now unoccupied. For example, there are several rooms on this road that are now empty.

However, unlike the unoccupied rooms, the snow on the wrought iron gate in the courtyard of this house fell to the ground, and the snow in the courtyard also left traces of the gate being opened, and there were a row of footprints leading to the gate.

"Alajo Cave opens. Hermione said the opening spell to the iron door, and the door opened inward. There is little magical defense on this uninhabited dwelling. After walking through the small courtyard to the door of the room, Ryan first released a cloud of pink light that seeped through the cracks in the door and window of the house, and after making sure that there was no danger in the house, he opened the door with the same lockpicking charm.

"Fluorescent flickering. Upon entering the room, Ryan flashed his wand. The furnishings in this house are no different from the other rooms on the street, just simple furniture. Because the environment of this place is good, even if there is no occupancy for more than two months, there is not much dust in the room.

"Let's look around and see what clues we have. Ryan said to Hermione. "I just checked that there are no magic fluctuations in the room, so don't worry about the portkey or anything. However, for safety reasons, don't touch anything different. ”

"Understood. Hermione nodded, then raised her wand and followed Ryan. Because this temporary housing is not large, they quickly searched the first floor and cellar, and everything is normal here. However, when they made their way to the second-floor workshop, the two found something on the table in the workshop that wasn't supposed to be there.
