Drink 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 the gold cup of Hufflepuff stored by Gringotts Ribeiratrix Lestrange, it has a good relationship with the dementors, and it is not easy to ask them to help with a few hairs of her. After waiting for her husband and wife to die, the inheritance of her family's vault is in the hands of her younger sister Narcissa Malfoy or cousin Sirius Black, both of whom are acquaintances.

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

Even if you don't use it to find the Horcrux, you can use it in other places. If it is used for modification, it can even be used as a detector to find a certain creature or even a certain person.

It's just that the volume of this plate is a bit too big, so it's not very convenient to use.

Putting away Ravenclaw's crown, Zhang Xu asked the waiter: "Can this plate be made smaller? It can be worn like a watch."

The waiter thought for a while and replied: "Yes, but the distance shouldn'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 I can add some other functions?" Zhang Xu asked.

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

"You made this crystal plate?" 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.

"Introduce myself, my name is Tonya Tumanova, you can call me Tonya, I am the owner of this Tumanova shop." Tonya stretched out her hand to Zhang Xu.

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

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

Zhang Xu: OvO

"I'm a student at Boothbarton School of Witchcraft and Wizardry. I think no one in our school has never heard of your name." Tonya said with a smile, "I come back for Christmas every year, so we didn't meet two years ago. "

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

"Come up for a cup of tea, by the way, tell me what function you want to add." Dong Niya sent an invitation to Zhang Xu.

Zhang Xu followed Dong Niya up to the meeting room on the second floor of the shop. After letting Zhang Xu sit down, 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 Dongnya's family in the living room, with Dongnya, her parents and grandfather on it.

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

"My parents and grandpa have gone to Huaxia." Dong Niya 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 mathematics. Professor, he’s a Muggle like his grandfather. He went to work in a university in China last year. My mother is a witch and was a student of Boothbatten. I heard that magic can be taught in China’s universities, so I followed my father. When I went to Huaxia, she passed this store to me. My grandfather went to Huaxia to live with his father and mother in winter. I went back to St. Petersburg to see the store at Christmas, and my parents would come back during summer vacation."

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

"Yes." Tonya said to Zhang Xu, "If you don't mind, I invite you to spend this Christmas with me, just these few days we will study your detector together."

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

Zhang Xuxin is a ghost.

Zhang Xu noticed from the beginning that Dongnya directly called Furong's name. If the two of them were unfamiliar, Dongnya should call Furong's last name Delacour.

If Zhang Xu agrees, he may fall into the pit dug by Dong Niya, or the grape rack in the backyard may fall.

Moreover, Ravenclaw’s logo is an eagle, but it does not mean that Zhang Xu wants to be a village-wide eagle that soars on the balcony. He also has no plans to install floor heating or WiFi on his balcony.

Then Zhang Xu declined Dongnya's invitation on the grounds of visiting the sick Gabriel.

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

Naturally, Zhang Xu would not tell Dongni Yaming that it was used to detect Horcruxes, only that it was used to detect specific ghosts.

Since Harry had the Soul Shard of the Two-hole Socket Man in his head, the detector had to shield the signal from Harry first.

Then we must block the signals of the ghosts in Hogwarts.

In addition, sound, light, and vibration alarm functions must be installed.

Since the detector is set in the style of a watch, simply add the watch's time, calendar, alarm clock, notepad and other functions, and it is usually used as a watch.

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

Unlike Hogwarts who took alchemy as an elective course in the sixth and seventh grades, Bussbarton had always taken alchemy as a compulsory subject because of Nico Lemay, and the professor was Nico Lemay. plum.

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

Therefore, at the level of alchemy, the students of Boothbatton can dump several of the students of Hogwarts.

Fortunately, Zhang Xu has been learning alchemy by himself. His knowledge of alchemy comes from two aspects, one is the inheritance (ke) (ben) of the ancient Chinese alchemy master Zou Yan, and the other is Nico Lemay.

In the past two years, the number of letters Zhang Xu wrote to Nick Lemay for advice on alchemy was second only to the number of letters to Furong, and slightly higher than the number of letters to Gabriel ~www.readwn.com~ Source, so Zhang Xu and Dong Niya did not encounter any major obstacles when discussing.

The first thing they solved was the functions on the watch. These were not major problems, and mature technology was available.

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

In the end, the two of them managed to solve 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 is the hands-on part of Tonya.

In the past few days, Zhang Xu has also been stunned by Dong Niya. Sometimes the two of them were still discussing whether the display time should be displayed in analog or digital format. The next moment she would ask Zhang Xu, She and Furong are pretty, if it was her who greeted Zhang Xu, would Zhang Xu find her to be a girlfriend? If she and Furong fell into the water at the same time, which one would Zhang Xu save first?

As soon as the design work was completed, Zhang Xu ran to France to give Gabriel the medicine.
