Just when the two of them had a leisurely tea party in the Ravenclaw lounge.

Almost all the aisles of Hogwarts Castle have been turned upside down.

Hermione's pet, the fat Crookshan, was leading the run in front of a group of guards, ginger's chubby body showing a completely inappropriate agility, hair all over his body stood on end, full of aggression, his flat face fell into an angry mood, and his apricot eyes were squeezed together.

At first glance, it seems that they are being driven away by this group of guards, and they look embarrassed, but this is an illusion.

In fact, it's leading the way.

The raccoon breed made it sensitive, and it sensed that Hermione was in danger.

Ron and Harry followed breathlessly, as well as the weeping Myrtle, who had now been rescued, floating on Professor McGonagall's shoulder, waving her arms urgently, as if to apologize.

The commotion just now was a bit loud, and the two people in the classroom were very embarrassed by Myrtle.

"Potter, Weasley, you can go to Miss Granger, she may be in some danger, Hogwarts must have an outsider invasion at the moment, as for Crookshan, you should know where her location is, now Flitwick and I have to search for the intruders. ”

The old lady said vigorously, then lifted herself in her black spiky hat and turned around with the diminutive Flitwick towards another path that had not been searched.

After Professor McGonagall handed over the assignment to the two, the group parted ways.

The two of them hurried upstairs in the direction of Dumbledore's office, and some of the black-armored guards were shunted behind them.

As for Professor McGonagall, she quickly reached the end of the hallway, where she and Professor Flitwick stopped in front of the Ravenclaw common room.

They patrolled here.

There was a knock on the door, and the sound of uniform footsteps resounded in the hallway.

Rapid and rhythmic at the same time.

"Visiting the Ravenclaw Lounge, questions need to be answered to get in. The gentle voice sounded again.

"Filius!" Malfoy and Luna heard Professor McGonagall calling out to Flitwick again.

The dean of Ravenclaw must not be stumped by the test of his own college's common room.

Flitwick stepped up to the front, and for him, it should have been a piece of cake.

It's just that today, maybe an exception will be made.

The door began to ask questions in a soft voice.

"Excuse me, a ship that has been at sea for hundreds of years, its captain is a Muggle, not a wizard, and he doesn't put a levitation charm or any other spell on the hull, and it lasts so long, all thanks to the crew's constant repairs and replacement parts of the ship, as long as a plank rots, it will be replaced, and so on, until all the functional parts are not the original ones, the question is, the final ship is still not the original ship, even if all the parts have been replaced, if not, at what point in time has the nature of the ship changedWhen the first part is replaced, or is it the last piece that is replaced, or is it somewhere in between?"

The gate spoke very quickly, and asked the lengthy question.

The dull footsteps of the Iron Guard outside the house stopped, and the air cut by the wind blade stopped.

Flitwick had a look of utter surprise on his face.

Rather, there was an unspeakable silence.

The air seemed to freeze with embarrassment.

Professor McGonagall's eagle-like eyebrows twisted.

This question left both Gryffindor and the Dean of Ravenclaw pondering.

But after a while, they still didn't come up with an answer.

"I don't know if that ship will be the same ship or not, I just know that if you don't open the door again, one of the doors will be torn down. ”

Professor McGonagall's temper was starting to get irritable, and if it was usual, she would have left, but this was not the same time, and the blow of Dumbledore's death made her less patient.

"New question entry - what decisions should we make in the face of the absolute threat of force?"

Then the Ravenclaw door answered honestly and in a physical way—and he quickly opened it.

I don't have the courage to look at death at all.

However, isn't it too demanding to talk about courage for a door?

It was only after the two of them stepped into the door that they heard a light and fluttering greeting.

"Hello, Professor McGonagall, and Professor Flitwick, how are you? Would you like to try the cookies? Luna sat down in her chair and waved at them.

She sat alone in a fluffy blue chair, her calves bobbing back and forth, and she looked comfortable as she brought the snacks her father had prepared for her into her mouth.

If there were a few more people, they might have thought there was a tea party going on in the Ravenclaw lounge.

Seeing the two walk in, Luna stood up and politely greeted them again.

"Miss Lovegood, has anyone come in before?" Professor McGonagall stood at the table, frowning, not accepting the invitation to taste.

"I don't know, I didn't pay attention. Luna shook her head in confusion.

"Don't you think it's blasphemy to focus on something else while you're concentrating on delicious food?" Luna asked rhetorically.

The two of them were speechless.

"By the way, Professor McGonagall, if you did tear down the Ravenclaw door and put it in the Gryffindor common room, would it still be the same door?" Luna asked the same question abruptly.

Professor McGonagall's face turned even pale.

"Let's go. She said to Flitvier.

The two departed, and after they left her with a back, Luna quickly waved her hand at one of the armor-clad Iron Guards in front of the door.

"Have a nice trip. She said with her mouth shape, and stuck out her tongue mischievously.

"If you have strength but no precious wisdom, you will be deceived. ”

She whispered.

McGonagall and Flitwick leave the Ravenclaw common room.

With the group of ironclad soldiers in the castle, they continued to march in unison.

Everywhere they went, the two would cast a spell to detect nearby fluctuations in magic, as the intruder might have used a disillusionment charm to evade their search.

Then they have to use a counterspell to touch it.

Of course, they never imagined that when they focused on Luna just now, there was already a person who had quietly blended into the torrent of steel legions.

Avoided their probes.

"Crunch, crunch. McGonagall led the group down the alley.

"Tap, tap. What she didn't see was that at the end of the Black Iron Army she controlled, a soldier had fallen behind.

Even after falling behind, the soldier still kept the same footsteps as them, but changed from marching to standing still, and finally completely broke away from the group, and disappeared.
