In the Headmaster's office, Dumbledore fiddled with the crystal ball like a child with a new toy, injecting magic into the ball and placing it on the magic items on the table. During this time, he also took a strange object and put it on the crystal ball, which immediately emitted a red light and a loud alarm sound and violent vibration, startling Filch, who was reporting to him.

After listening to Filch's report, Dumbledore motioned for him to sit down and have a cup of tea and then a honey cake, and then looked at Zhang Xu, who was sitting on the side and eating a snack while drinking tea.

"Mr. Zhang, I think your analysis is correct, and thank you very much for what you have done to Argus. It was my negligence and incompetence that had caused Argus to suffer for so many years. ”

What Dumbledore said to Zhang Xu made Filch on the side excited.

Zhang Xu thought to himself, if Dumbledore told Filch at this time that Voldemort was now on the back of Quirrell's head, and then handed him ten pounds of C four, Filch would definitely rush over and die with Quirrell, maybe "Harry Potter" could end one or two episodes earlier.

"No thanks, Mr. Filch is a dedicated administrator, and it's a pleasure to help him."

"Mr. Zhang, do you have any comments or suggestions for Argus' treatment?"

Zhang Xu thought for a while and said the answer that had been considered: "I once saw several records of similar cases in the family collection, and these symptoms were called ...... Well, translated into English it is 'magic ice'. ”

It's not Zhang Xu bragging here, Zhang Xu's family is good at pills, and there are many rare cases and treatments recorded in the family collection. If it weren't for the fact that the regional differences between the medicinal plants and animals of the East and the West were too strong, and the descriptions of the drugs on both sides were not systematic, even Zhang Xu and Snape ran into a wall when they tried to analyze the differences between the Eastern and Western potions, and finally only analyzed a fireproof potion made of common magic minerals, otherwise Zhang Xu, who has a family history, would be able to hang his classmates who were two grades higher than him on the potion. In terms of refining potions, Zhang Xu had almost beaten the whole school. And Zhang Xu's "Potions Class Safety Management System" and "Potions Class Self-Inspection Management Specification" were even more valued by Snape, and they added thirty points to the Eagle House for the first time in history. After Neville sent himself and his classmates to the school infirmary during a Potions class, Snape said that if Neville could memorize these two items and obey them, then no one would be hurt in Potions class in the future, and ordered Harry to take charge of having Neville carry the two things.

Therefore, Dumbledore, who knew that Zhang Xu had a good performance in potions, would consult Zhang Xu's opinion.

"To heal magic ice, it's like to make ice turn into water, and to make all the magic that is still move," Zhang Xu continued.

"The magic in a normal wizard's body is constantly in motion, as long as you give a huge boost to the still magic, let the originally static magic start working, and then add proper magic practice, the magic can quickly return to the normal wizard.

"And the most critical part of the healing is the driving force that pushes the whole magic into action at once. If the push force is small, it will not work, and if the push force is too large, it will cause irreversible damage to the flesh.

"Most of the cases of healing recorded in my family are using a potion that accelerates the power of magic. And this potion is also a poison. The effect of this poison is to make the poisoned wizard's whole body magic speed up uncontrollably, causing the magic to go out of control. Therefore, while taking this potion, it is also necessary to prepare antidotes and potions to heal human damage.

"I suggest that Professor Snape and Madam Pomfrey be involved in the treatment of Mr. Filch."

As soon as the topic changed, Zhang Xu did not take the opportunity to sell his own elixir, but sold his favor to Hogwarts.

For bulls of the level of Dumbledore, the number one wizard in Europe, Snape, the top Potions expert in Europe, and Madam Pomfrey, the biggest hidden boss in Hogwarts, the most precious thing is not how to do it in detail, but how to solve the problem. As long as there is a general direction, the details of solving the problem are not a problem for them at all.

If Hogwarts were able to master the treatment of the Squibs through this treatment of Filch, then the tangible and intangible benefits for Hogwarts in the wizarding world would be enormous.

And these benefits are a bit chicken for the current Zhang Xu and the Huaxia Fangshi world behind Zhang Xu.

For Zhang Xu, the most he can get is a Merlin Medal. He didn't plan to mix in Europe in the future, and when he returned to China, the Merlin Medal couldn't add points to the college entrance examination. After the other monks figured out the reason why Zhang Xu won the Merlin Medal, they would only smile and say that this goods would go to the foreigners with a disease that could be cured by a tertiary hospital.

If you sell medicine in the name of the Huaxia Fangshi community, it is very likely that it will be resisted by the conservative and xenophobic European wizarding community, even if you don't know how to resist it, if the Ministry of Magic deliberately delays the process, maybe Harry Potter's son will not finish the process when he goes to school.

But if this proceeds are sold to Hogwarts, which has already extended an olive branch to the Huaxia Fangshi world, Hogwarts will naturally offer a good price, and then it will be a win-win situation for all parties.

The veteran Dumbledore apparently figured out the doorway in an instant. Dumbledore smiled and added a lot of desserts to Zhang Xu, and told Zhang Xu in this way, "Little brother, I understand." ”

Snape and Madam Pomfrey were soon called out to by Dumbledore.

Dumbledore told the two of them about Filch's situation and Zhang Xu's treatment ideas, and after thinking about it, Snape and Madam Pomfrey nodded their heads one after another, indicating that this could be done.

Snape stated that the corresponding matching potions would take some time to develop.

Madam Pomfrey stated that she would use Professor Snape's potions to develop adjunctive treatment and contingency plans.

Dumbledore immediately decided to set up a special research and treatment team for the "Magic Ice" disease at Hogwarts School of Witchcraft and Wizardry.

Team Leader: Albus Dumbledore

Consultant and Researcher: Xu Zhang

Deputy Team Leader: Severus Snape

Deputy Team Leader: Mrs. Bobby Pomfrey

Researcher: Argus Filch

The first plenary meeting of the Group, held on-site, adopted the following resolutions:

1. Starting tomorrow, all the team members will gather in the Potions classroom at 7 o'clock every night to study and be studied.

2. Hogwarts School of Witchcraft and Wizardry has approved 1,000 Galleons as the first research funding.

3. The team will increase the number of personnel according to the specific situation.

4. It's getting late now, and it's time for Zhang Xu, who is a student, to go back to sleep.
