As the Black incident was resolved, the Dementors around Hogwarts also evacuated, and the speed was so fast that Zhang Xu couldn't find them to deliver a boxed lunch.

After Scarlet knew that the ring was a Horcrux and that the Dementor could solve the problem of the Horcrux without damage, she temporarily handed the ring to Zhang Xu to deal with.

As for the curse on the ring, it shouldn't have much effect on the dementors, just go to the stone when you eat, Zhang Xu thought.

In the days that followed, the students regained their former vigor, much to the surprise of Blake, who had been away from Hogwarts for many years.

Black is still living in the school infirmary, lying in a hospital bed during the day, and Harry delivers three meals a day. After dinner, he had two hours to relax, and he also went out for a walk with Harry every day, telling Harry about his glorious past with Harry's father.

Through Harry's retelling, Zhang Xu learned that after entering Hogwarts Castle for the second time, Blake faced Scarlet's pursuit, and he ran to Hogwarts' Squib and Werewolf treatment point in Hogsmeade as a stray dog, and was "adopted" by Madam Pomfrey for a while.

Black also sent out job applications to Dumbledore and Madam Pomfrey to manage the medical site when he was well, so that Madam Pomfrey would not have to close the doors while she was in the Hogwarts infirmary. Blake's other mind, of course, was to create opportunities to be with Harry. Eventually, Dumbledore agreed to Black's request.

It's Easter fast, and the students at Hogwarts have a holiday full of homework.

The Easter holidays were followed by the Lion House and the Snake House Quidditch matches, with the Snake House team on a two-game losing streak and the Lions House team trying to create a last-minute comeback against each other, both in terms of playing and playing players.

The Snake Courtyard team, which had their backs to the water, played a murderous game in the game, and all the players on both sides of the court were injured.

Even Draco Malfoy was knocked out of the air and into the stands by Harry when he was thwarting Harry Potter from fighting for the Golden Snitch, and the bloody Malfoy picked up the broom and returned to the sky to continue to interfere with Harry. With the broomstick not in hand, Malfoy made it impossible for Harry to catch the snitch four times when he first spotted the Golden Snitch.

In the end, when Harry caught the Golden Snitch, the Lion House was only twenty points ahead of the Snake Yard.

Time passed around Hogwarts, creeping into the last Hogsmeade week of the school year.

Because today is the last Hogsmeade week in the seventh year graduates' student careers, the curfew time for returning to Hogwarts has been relaxed until 10 p.m. today.

Zhang Xu was wandering around Hogmodri at will, he had just come out of the pig's head bar, the latest transaction between their family and Lao Ma's family had been completed, and the goods ordered from Lao Ma's family had been sent away through special channels.

Zhang Xu slipped to Hogwarts' Squib and Werewolf treatment site in Hogsmeade, and saw that Blake, who was working there, was sending out a wizard who had just been treated with a Squib.

Ever since Blake saw Zhang Xu coming out of Scarlett's dormitory that night, he had been hostile to Zhang Xu, and Zhang Xu didn't bother to pay attention to him.

Blake's misunderstanding of the relationship between Zhang Xu and Scarlett, Zhang Xu didn't explain anything to him, Zhang Xu was not familiar with him, and Scarlet was not interested in him.

It's all Blake's own self-inflicted passion.

Zhang Xu walked up to the second floor, and the pressure cooker with the "Elune" potion was sizzling in several rooms. Tonight is the night of the full moon, and the werewolves waiting to be healed have settled in Hogsmeade, where Snape will be taking a few of the senior students to make the final step of the potion for them.

Zhang Xu came to Madam Pomfrey's office and asked about the stock of some medicinal materials, some of which were provided by Zhang Xu's family.

With the werewolves who came to be treated in the past few months all cured, now the number of werewolves who came for treatment has begun to increase, and the werewolves who are interested in treatment have also written to inquire about the situation. As more and more werewolves are cured, the number of werewolves coming for treatment will explode in the foreseeable future. As a result, the current size of the healing site and the stock of medicinal materials are obviously insufficient, and Dumbledore has considered expanding the area, or moving to a larger location.

Madam Pomfrey gave Zhang Xu a large list of medicinal materials, which were all urgently needed at the moment.

Werewolves have always been a nightmare in the wizarding world, and werewolves are seen as a great shame in the wizarding society.

Werewolves often lose their minds when they transform on a full moon night, and Snape almost died at Lupin's hands in the first place.

Many werewolves who are unwilling to harm others will go to deserted places before the full moon, or lock themselves in sturdy houses to survive their transformation.

If someone is bitten by a transformed werewolf, they will be infected and become a werewolf.

Moreover, the magic resistance of werewolves is much higher than that of ordinary wizards, and the effect of the spell on them will shrink, and wizards are very difficult to deal with.

Fearful of the danger and contagion of werewolves, werewolves have long been subjected to hostility and discrimination from both the private and official authorities of the wizarding society, which makes them alien to mainstream society, as can be seen from Lupin's embarrassing life before he became a teacher at Hogwarts.

Emmoret Piccardy once wrote a book about werewolves called "The Wolf Who Corrupted Law: Why Werewolves Don't Deserve to Live", in which the author claims that even werewolves in human form are lawless and morally deficient. Although this statement is false, it also represents the opinion of some people who are afraid of werewolves and lack understanding.

In the Beasts Office of the Department of Magical Beasts Management and Control of the Ministry of Magic, there is a department called the Werewolf Registry, which is responsible for managing and maintaining the Werewolf Registry, which records all known werewolves in the United Kingdom.

In 1637, the British Ministry of Magic developed a series of Werewolf Code of Conduct that set out the responsibilities of werewolves, but the code of conduct failed because no one signed it.

Werewolves, who have suffered from both civil and official hostility and discrimination, have been living in hardship for a long time. Most of them do not become werewolves voluntarily, and they also yearn for a normal life. It's just that the drugs that have appeared for a long time to treat werewolves are either wolf poison drugs that treat the symptoms but not the root cause, or they are simply fake drugs.

Now the werewolves have a chance to be healed, and this opportunity comes from Hogwarts, the famous British school of witchcraft and wizardry, instead of the small advertisements posted on the wall at the corner of Diagon Alley, which has made countless families and individuals who have been plagued by werewolves ecstatic.

But not all werewolves want to be cured.

There is a group of werewolves who hope to one day create enough werewolves to rule the wizarding world. This is an army of werewolves led by Fenrir Greyback, who make it their mission to bite and infect as many people as possible.

Fenrir Greyback could have imagined that after Hogwarts launched "Elune", which could heal werewolves, the number of werewolves would inevitably decrease and decrease, which undoubtedly dug their roots.

Desperate, Fenrir Greyback decided to take a desperate gamble and launch a terrorist attack on Hogwarts' treatment site in Hogsmeade, in an attempt to warn werewolves who were desperate for treatment to abandon it.

It's just that because of Black's escape, Hogsmeade was surrounded by patrolling Dementors, which forced Fenrir Greyback to postpone his plans.

So on the night of the full moon after the Dementors had withdrawn, Fenrir Greyback realized that the time had come, and led his men to infiltrate the vicinity of Hogsmeade, and when the full moon climbed up, he attacked.

Looking at the werewolves rushing from afar, Zhang Xu, who was barbecuing on a grass outside Hogsmeade with Harry's trio and a few other friends, reluctantly ate the kebab in his hand in a few gulps, and after popping out his wand and releasing a signal representing an emergency in the sky, he took out the Type 81-1 automatic rifle from the treasure bag, replaced it with a steel core bullet and began to shoot at the werewolves in the distance.
