He no longer needed to ask Professor McGonagall for leave and continued to be responsible for ensuring the safety of the exam students as usual until the History of Magic exam was over in a few days.

According to Hogwarts tradition, History of Magic represents the last exam, and this also applies to OWL and NEWT exams.

Even Professor McGonagall came early that morning, and would appear in the hall from time to time to supervise all the seventh-year students writing their exams.

Although Professor Marchbank repeatedly stated that everything was normal and there was no difference from the previous exams, she just couldn't calm down. She stayed in the principal's office for a while and then came over to take a look.

After all the test papers were collected, the Hogwarts Castle, which had been silent for many days, suddenly burst into cheers.

"I don't have to do homework anymore!" Ron stood in front of the window and threw "A History of Magic" in his hand out of the window.

"Ron!" Hermione glared at him in dissatisfaction from behind, "How could you do this?"

"Ah, never mind," Ron shrugged. "Ginny already has a History of Magic. I don't need to keep the old one."

There are many Weasley children, and there are children from almost every grade. Sometimes a book can be passed around to several people in a row.

For example, the "History of Magic" he just threw out was the one Charlie used.

There was also the Advanced Transfiguration Guide used in the sixth grade Transfiguration class, which was also left by Bill. When it came into his hands, it was so old that even the cover was wrinkled.

According to the Weasley family tradition, this book would have been left to Ginny, but Fred and George couldn't stand it anymore, so they bought all the new books for Ginny.

Hermione also knew this.

"That's not what I meant!" she said unhappily, but she didn't blame Ron anymore.

Many students poured out of the castle and came to the field outside.

Kyle was among them.

Connor also came to Hogwarts today. Kyle watched her pour a bottle of blue potion into the Black Lake and asked in confusion: "Why did you suddenly think of brewing mermaid tonic... Is this also the potion formula that Dean Sassia gave you?"

Kyle couldn't understand why Sassia, as the headmaster of St. Mungo's, had a tonic formula for magical creatures. Wasn't this something that only Newt would be interested in? Could it be that St. Mungo's had a magical creature treatment department that he didn't know about? "This is not a tonic, it's a gill sac potion I brewed," Connor explained.

"Gill Pouch Potion, what is this?" Kyle asked with a frown.

"It's a potion similar to Gillyweed that can make a person grow gills and flippers underwater, and it lasts for half a day."

"So that's how it is." Kyle nodded in realization.

He understood what I meant. It was an enhanced version of Gillyweed...similar to Dictamni and hemostatic potion.

"Then why did you fall into the Black Lake?" Kyle glanced at her. "Do you think the mermaids in the Black Lake need to grow another pair of gills?"

"That's because I... did something wrong..." Kanna's voice became much softer when she said this.

"Uncle Snape's storage room only has the collected gillyweed. Although it can grow gills and webbed feet after taking it, it is obvious that fresher ones are needed to make potions."

Kanna took out another flask and poured the blue potion into the black lake.

“But Uncle Snape said that although this failed potion cannot make wizards grow gills, it has many benefits for magical animals living in the water.

"It just so happened that I came to Hogwarts to see Professor McGonagall today, so I wanted to see the effect in the Black Lake."

Kanna squatted by the Black Lake and looked at the water.

The mermaid didn't come, but the giant squid, which was now gulping down the lake water on the shore like Sybill Trelawney seeing sherry.

It is not difficult to see from its reaction that this failed product can be considered a success in a sense.

Kanna quickly took note of the changes in the giant squid's movements.

"Snape..." Kyle glanced at the castle behind him. "When did he leave Hogwarts?"

"It's been a long time, probably since the day the NEWT exam started." Connor said, "Why, you didn't know?"

To be honest, Kyle really didn't know. He always thought that Snape didn't want to face the students and professors, so he never went to the auditorium to eat.

Besides, he had a lot of things to do these days, so it was impossible for him to keep an eye on Snape... Of course, even if he had nothing to do, he would not stare at Snape.

"You just said you came to Hogwarts to see Professor McGonagall?" Kyle deliberately changed the subject, "What's the matter? Do you need my help?"

"No." Connor shook her head, "It's about the hearing. Yesterday the Wizengamot sent a letter to Uncle Snape with the date of the second hearing.

"Professor McGonagall told us to let her know when we receive the letter."

"when?"

"It just happened to be the day Hogwarts was closed for the holiday."

"That's great. I'll go there too."

"Um."

The two chatted, and not long after, Professor McGonagall and the people from the Wizarding Examinations Authority walked out of the castle and watched them leave Hogwarts.

Kanna walked over immediately.

She had arrived a long time ago, but the History of Magic exam was still being held in the castle at that time, so she did not go in to disturb Professor McGonagall and waited outside with Kyle.

Kyle watched Professor McGonagall lead Connor into the castle but did not follow.

There was little help he could offer at Snape's second hearing, and it would be useless even if he followed along.

"Kyle!" Hagrid came over from not far away, "I'm going to take Harry and the others to Hogsmeade and have a glass of mead. Do you want to come with us?"

When Hagrid came closer, Kyle noticed that Harry, Ron and Hermione were following him.

Under normal circumstances, even after the exams, Hogwarts does not allow students to leave the school early and go to other places, including Hogsmeade.

But they are all in seventh grade this year, and the school's restrictions on adult wizards are relatively relaxed.

And Hagrid is with him, so even if Professor McGonagall knew, she wouldn't say anything.

"I'm not going." Kyle waved his hand and rejected Hagrid's invitation.

Hagrid didn't care and turned around and led the three of them towards the school gate.

"Kyle... um, Professor..."

It's always extra lively after the exams. Just after seeing Hagrid off, someone else came over.

This time it was a few seventh-year students, with Justin Finch-Fletchley from Hufflepuff walking in the front, along with his inseparable MacMillan, and Neville from Gryffindor.

Before he graduated, these people were considered his good friends, and Justin even went to the kitchen with him for midnight snacks several times.

So even though Kyle stayed on as a professor, their name could never be changed.

Justin ran over from a distance and asked impatiently: "We want to hold a party, how about you come and join us?"

"Banquet?" Kyle looked at him, then at Neville, "Or are both colleges together? "Are you going to the tower, or are you going to let Gryffindor come to the kitchen... I must remind you that even if you are graduates, some things can't be too extreme, otherwise Professor McGonagall can still put you in detention before the holidays."

"No, it's not two colleges together, it's four... well, to be exact, it should be three." McMillan stepped forward to explain: "And we guarantee that this banquet will not be discovered by Professor McGonagall."

"DA's secret base."

"DA?" Kyle was in a daze. "Dumbledore's Army?"

"That's right." Neville nodded, with a hint of pride and confidence on his face that was never there before.

"All the members who joined the DA stayed during the last war, and each of us abided by the original agreement."

After the war, Neville became much more confident. His grandmother, Mrs. Longbottom, once suspected that Neville was impersonated by someone else and insisted on using the Apparition spell on him.

Fortunately, Professor McGonagall stopped him in time.

"Yeah." Justin said, "It's just that... the DA has successfully completed its mission. It's time to disband. We want to celebrate again."

When DA was founded, most of the participants were senior students. When Kyle graduated last year, the number of members was reduced by nearly half, and this year, when their class graduates, the number will be reduced by half again.

There may be less than ten people left, which is no different from disbanding.

Of course, it was only a disbandment in name only.

At least for a long time afterwards, they will remember their special identity and be proud of it.

After all, among so many clubs in Hogwarts, only the DA had all its members participate in the war against Voldemort and won.

"Including this banquet, only members of the DA can attend. Potter and Granger went to buy butterbeer, and someone else is setting up the banquet venue on the eighth floor."

"So come along, I dare say this will be the most lively party." Justin invited again.

Kyle didn't refuse this time, he just said he could go and have a look when the time comes.

The three of them looked very happy, and after chatting with Kyle for a while, they quickly returned to the castle.

At this time, Kanna just walked out of the castle.

"What Professor McGonagall said."

"She said she would go to the Ministry that day and told me not to worry."

"You really don't need to worry." Kyle smiled. Professor McGonagall handed over all the Horcruxes to the Ministry of Magic, so they certainly wouldn't make things difficult for Snape.

"What about Snape... Professor? He let you come here alone?"

"He doesn't want to go out." Connor sighed.

"Ever since the last hearing, Aurors have been watching his every move, and Uncle Snape doesn't want to see them, so I'm here."

"Auror...is it troublesome?" Kyle asked.

He suddenly remembered that the current head of the Auror Office was Kingsley, with whom he had a good relationship. In addition, he had always been ashamed of the "Horcrux" before. If he went to find him, perhaps he could lift the surveillance on Snape.

Originally, after the Horcrux was handed over, this second hearing became a formality. No matter how stupid Snape was, he couldn't escape at this time.

But Snape clearly disliked the Auror's surveillance. He was unhappy, and Kyle was happy.

So Kyle has been hesitating whether to go find Kingsley.

"If it's troublesome, there is a little bit." Connor whispered: "Every time Uncle Snape sees the Aurors outside the window, he will be in a bad mood. Although he never says it, I can see it."

"Oh..." Kyle's mouth curled up slightly, then quickly recovered.

"Is that all?" he asked.

"Also, there's no way to buy ingredients." Kanna thought for a moment, "Some of the ingredients in the potions I'm learning now are not available in Diagon Alley, so I have to go to some... not so safe places to buy them.

"But now that the Aurors are watching, Uncle Snape definitely won't be able to go, and he insists on not telling me the address."

"I see." Kyle said, his thoughts wavering a little.

Although Snape's bad mood was pleasant news, Kyle didn't expect that it would also affect Connor.

Indeed, to brew potions, especially complex potions, those forbidden materials are essential.

As a potion master, Snape naturally has his own way. Of course, it's definitely not very formal.

Connor didn't know what Kyle was thinking, so she continued walking and said, "I went to Diagon Alley to look for fresh gillyweed for a long time but couldn't find any, and Uncle Snape wouldn't tell me where to buy it."

"Wait." Kyle suddenly stopped Kanna, "The potion you need is Gillyweed?"

"Yes." Kanna nodded. "That thing is too hard to find, especially if it has not been collected. There is none in the UK. The only way is to go to the Mediterranean, but I can't go that far now."

"Who said that?" Kyle laughed and grabbed Kanna.

"Come with me."

He ran quickly towards the cabin, and Kanna had no choice but to follow him because she was being pulled.

After returning to the cabin, Kyle didn't say anything. Instead, he put the box on the ground, opened it, and jumped straight in.

"Kyle, you..."

Before the confused Kanna could ask, Kyle disappeared.

She had no choice but to jump into the box.

Afterwards, Kyle took her straight to the only lake in the box and stopped at a place with an empty flower pot. There used to be some biting kale here, but now there were only a dozen or so left.

"Kyle, why did you bring me here?" Kanna finally found a chance to speak.

"Don't you want fresh gillyweed?" Kyle took out his wand and pointed it at the water surface. "Take a look at these. Are they what you want?"

The surface of the water parted, revealing a horse-shaped water monster eating below.

Connor blinked in confusion, not understanding why Kyle asked her to look at the Kelpie, until she noticed the coral-like thing in its mouth.

"Gills... Gillyweed..." Her eyes widened.

Leaves like water plants and roots like corals, this is what the branchial grass originally looked like, and there are quite a lot of them.

There is a large area under the lake.

"You, how come... isn't it said that this plant is difficult to grow on a large scale in the UK?"

"I don't know either."

Kyle shrugged. "I bought this thing from Diagon Alley, and then I just left it here and forgot about it. If it weren't for the Kelpie, I probably wouldn't have known there was such a large patch of gillyweed under the lake."
