Drinking black tea calmly at Hogwarts

Now that Ravenclaw's crown is in Zhang Xu's hands, it is not difficult to get Slytherin's locket after solving Black's problem.

As for Hufflepuff's gold cup kept by Bellatrix Lestrange in Gringotts, she has a good relationship with the dementors, and it is not easy to ask them to help her with a few hairs.Worse, after the death of her husband and wife, the inheritance of her family's treasury will be in the hands of her sister Narcissa Malfoy or her cousin Sirius Black, both of whom are acquaintances.

If you want to get Slytherin's locket and Hufflepuff's gold cup in advance, and solve the problem of Harry's soul, this crystal disc detector that can find Horcruxes will be very useful.

Even if it is not used to find Horcruxes, it can be used in other places.If it is used and modified, it can even be used as a detector to find a certain kind of creature or even a certain person.

It's just that the plate is too big and it's not convenient to use.

Putting away Ravenclaw's crown, Zhang Xu asked the waiter, "May I ask if this plate can be made smaller so that it can be worn on your hand like a watch?"

The waiter thought for a while and replied, "Yes, but the distance can't be too far."

"It doesn't need to be too far, just one or two meters." Zhang Xu said.

The waiter nodded and said yes.

"I wonder if some other functions can be added," Zhang Xu asked.

"What function do you want to add? If it's too complicated, I can't do anything." The waiter said.

"You made this crystal dish," Zhang Xu asked in surprise.

"Yes, many of the products in this store are made by myself." The other party replied.

"Sorry, I thought you were just a waiter in the store." Zhang Xu said.

"Let me introduce myself. My name is Dongnia Tumanova. You can call me Dongnia. I am the owner of this small Tumanova shop." Dongia held out her hand to Zhang Xu.

"Nice to meet you, my name is Zhang Xu, a student of Hogwarts School of Witchcraft and Witchcraft." Zhang Xu shook hands with Dongia.

"So you are Fu Rong's boyfriend." Dong Niya said to Zhang Xu with a smile.

Zhang Xu: ovo

"I'm a student at Beauxbaton School of Witchcraft and Wizardry, and I don't think anyone in our school has heard of your name." Tonya said with a smile, "I come back every year for Christmas, so we didn't meet two years ago. "

After knowing the identity of the other party, the conversation between the two became much easier.

"Come up and have a cup of tea. By the way, tell me what function you want to add." Dong Niya extended an invitation to Zhang Xu.

Zhang Xu followed Dong Niya to the living room on the second floor of the store. After Zhang Xu was seated, Dong Niya went to the kitchen to prepare refreshments.

Soon, Tonya prepared black tea with sugar and lemon slices, a plate of cake and a plate of biscuits.

Zhang Xu saw a group photo of Dongniya's family in the living room, with Dongniya, her parents and grandpa on it.

"Are you the only one in your house?" Zhang Xu asked.

"Both my parents and my grandpa have gone to Huaxia." Tonya said, "My grandpa is a professor of physics and worked in China for many years 40 years ago. I learned Chinese from him. My father is a professor of mathematics. , is a Muggle just like my grandfather, and he went to work in a university in Huaxia last year. My mother is a witch, and she used to be a student of Beauxbatons. I heard that magic can be taught in universities in Huaxia, so I followed my father. When Huaxia was born, she passed on the store to me. My grandfather went to Huaxia to live with my parents in winter. I went back to St. Petersburg to visit the store at Christmas, and my parents would come back during the summer vacation.”

"So you spend Christmas alone?" Zhang Xu asked.

"Yes." Dong Niya said to Zhang Xu, "If you don't mind, I invite you to spend Christmas with me this year, and it happens that we will study your detector together in these few days."

Then Dong Niya smiled and said to Zhang Xu: "Don't worry, I won't tell Fu Rong."

Zhang Xu believes that she is a ghost.

Zhang Xu noticed from the very beginning that Dongnia called Furong's name directly. If the two of them were not familiar, Dongnia should call Furong's surname Delacour.

If Zhang Xu agreed, he might have fallen into the hole Dongia dug, or the grape trellis in the backyard would have collapsed.

Moreover, Ravenclaw's logo is an eagle, but that doesn't mean that Zhang Xu wants to be a village-wide eagle soaring on the balcony, and he has no plans to install floor heating and even wifi on his balcony.

Then Zhang Xu declined Dongia's invitation on the grounds that he wanted to visit the sick Gabriel.

Next, Zhang Xu began to discuss with Dongiya about making a Horcrux detector.

Naturally, Zhang Xu would not tell Dongia that this was used to detect Horcruxes, but only that it was used to detect specific ghosts.

Since Harry has the soul fragment of the man with the double socket in his head, the detector must first block the signal from Harry.

Then we have to block the signals of the ghosts in Hogwarts.

In addition, sound, light and vibration alarm functions should be added.

Since the detector is set in the style of a watch, simply add the time, calendar, alarm clock, notepad and other functions of the watch, and use it as a watch at ordinary times.

After determining the function of the detector, Zhang Xu and Dong Niya studied together how to realize the various functions of the detector.

Unlike Hogwarts, which took alchemy as an elective course for the sixth and seventh grades, Beauxbatons had always taken alchemy as a compulsory course because of Nicolas Flamel, and the professor was Nicolas Flamel.

In Britain, the main knowledge of alchemy, such as the making of broomsticks, has always been controlled by various families.

So at the level of alchemy, Beauxbatons' students can beat Hogwarts students by several English Channels.

Fortunately, Zhang Xu has been half-taught alchemy by himself.His alchemy knowledge comes from two sources, one is the inheritance of the ancient Chinese alchemy master Zou Yan, and the other is Nicolas Lemer.

In the past two years, the number of letters Zhang Xu wrote to Nick Lemay seeking advice on alchemy was second only to the letters to Furong, and slightly higher than the letters to Gabrielle.

Since the teachers came from the same source, Zhang Xu and Dong Niya did not encounter any major obstacles during the discussion.

The first thing the two of them solved was the functions on the watch. These are not big problems, and there are mature technologies available.

The difficulty lies in blocking specific signals. If this problem is not solved, don't expect to use it in Hogwarts.

In the end, the two barely solved the problem after referring to the principle of the radio.

The day before Christmas Eve, the two finally completed the design work, and the next step was Dongia's hands-on session.

In the past few days, Zhang Xu has also been teased by Dong Niya. Sometimes the two of them are discussing whether it is better to use an analog or a digital display time for the first minute, and the next moment she will ask Zhang Xu, for example Which one is prettier, she or Furong? If she was the one who greeted Zhang Xu, would Zhang Xu ask her to be his girlfriend? If she and Furong fell into the water at the same time, which one would Zhang Xu save first?

As soon as the final design work was completed, Zhang Xu ran to France as if fleeing for his life to give Gabriel medicine.
