When the smoke cleared, a pile of still beating flesh appeared, and the surrounding stone walls were splattered with iron sand and small pits, and a one-sided beating came to an end.

With a sudden sneak attack this time, Seamus had an absolute advantage at the beginning, so he could win this victory unscathed, and if he fought head-on, he might have to pay a big price. Of course, no wizard would give up his advantage and choose to go head-to-head with the trolls.

Seamus put away his broomstick, walked up to the troll, took out his wand, and split it several times in succession, cutting off the troll's head and giving it the final touch.

Putting away his wand, Seamus was about to leave, when the professors who had rushed to hear the news were late, and the roar of the explosion just now, the last roar of the troll, spread throughout the castle.

Professor McGonagall rushed in front of him, followed by Snape, Quirrell and Dumbledore at the end, Quirrell only glanced at the troll, then let out a feeble sob, and slumped to the ground.

Snape bent down to look at the troll, and Professor McGonagall looked at Seamus, her face pale and her voice tinged with cold anger, "What the hell are you doing? Why don't you stay in the dorm honestly?"

Snape looked up and glared at Seamus fiercely, "Maybe he thought it was a good time to be a hero, but now it seems that he has succeeded." ”

Seamus said without humility or arrogance: "I just came to see what the troll looked like, but I didn't expect to be discovered by it, and it ended up like this." ”

"Damn curiosity, Gryffindor will be deducted 5 points for you destroying school property. Snape said.

"Well, there are very few first-year wizards who can take on trolls, and you've earned 10 points for Gryffindor. "Now hurry back and the students are enjoying the Halloween dinner in their own college." ”

Seamus had long wanted to leave, the stench of the troll was unbearable, "Then Professor, I'll go back first." ”

Although Snape found a reason to deduct 5 points, Professor McGonagall added it back in the blink of an eye, and earned 5 points in a flash, which is also good news.

"Wait a minute, I have something to tell Mr. Finigan, come with me. Professor Dumbledore, who had not spoken since the beginning, said.

After saying that, the headmaster turned to leave, and Seamus hurriedly followed, and they kept walking upwards, constantly climbing the stairs, until they reached the 8th floor, and came to a stone statue.

Hogwarts is not good at this, there is no elevator beyond the 8th floor, and it always has to climb the stairs, and the stone statue saw Professor Dumbledore coming, and quickly pretended to be a serious guard, as if it was not it that was sleeping just now.

Professor Dumbledore walked up to it, and the stone statue quickly stepped out of the way, revealing the spiral staircase behind it, and they walked up the staircase, pushing open the wooden door, and inside was the Headmaster's room.

Inside, there are all kinds of silverware, a large row of bookshelves, and dozens of portraits on the walls. Those were the headmasters of Hogwarts from all over the ages, and when they came in, the portraits became noisy.

"Hey, young man, what did you do to bring you to the headmaster's office. The portrait of Phineas Nigelus gloated there, and it was desirable to see the panicked look on the little wizard's face.

This is Sirius's great-grandfather, one of the previous Headmasters of Hogwarts, and another portrait next to him speaks, "Leave that guy alone, the Headmaster's Office is not a dangerous place." ”

This painting is by Dalyse Devante, a former famous therapist.

"Thank you, Principal DeVante. Seamus replied politely.

"I'm not a headmaster anymore, the current headmaster is the one in front of you, and it's rare for anyone to remember me. "You could tell she was happy.

"Sit down, Mr. Fineggan. As soon as Dumbledore raised his hand, a chair placed across from Dumbledore automatically pulled open, leaving room for him to sit, "Do you want some cockroaches?"

Dumbledore's very polite invitation, those cockroach-like chocolates were piled up in the bowl, still crawling, Seamus wanted to refuse, but the curiosity in his heart still wanted to try it, so he simply sat on the chair, grabbed a cockroach that was still crawling, and stuffed it into his mouth.

The legs of cockroaches are particularly hard, and they taste a little prickly when eaten, and they taste good when chewed in other places, much better than chocolate frogs.

"Pretty good chocolate, if only it weren't so hard. Seamus expressed his satisfaction with the cockroach pile.

Dumbledore smiled and said, "Very few people can accept the cockroach pile, let me have to enjoy these delicacies alone, if you like, you can come back often in the future, remember that the password to enter the door is 'cockroach pile'".

As he spoke, he also picked up a pile of cockroaches, put it in his mouth and chewed it slowly.

"Forget it, I've eaten too much chocolate, I'm going to Madam Pomfrey, and I'm going to drink that nasty potion. Seamus said, "So Professor, what is the matter with you coming to me?"

"It's not a big deal, it's just that I was just on the scene and I saw those little holes in the walls, which shouldn't be something that spells can do. Dumbledore told why.

"It turned out to be this, it was really not a spell, it was a bomb I made myself. As he spoke, Seamus took out an iron ball and handed it to Professor Dumbledore, "Be careful not to let it explode, it's not small." ”

Professor Dumbledore took the iron ball in his hand and looked at it for a while, and said, "It turns out that this is this, the magic circle of Africa, I should have thought of it a long time ago." ”

"Yes, it's the magic circle of Africa. Seamus said calmly, he had no doubt about Dumbledore's insight, and it was not surprising that a man who was so idle that he had even learned the language of the fish-man knew anything.

"I also studied it for a while when I was younger, but unfortunately I couldn't figure it out too much, the mobile magic array inside always looks simple, but in fact it is too computational. Dumbledore sent the iron ball back to him, "If you want to dig deeper, it's best to understand the mobile magic array first, almost all advanced magic arrays need it. ”

"Thank you, Professor, I'll pay attention, that magic circle is really difficult. Seamus said.

Unexpectedly, Professor Dumbledore was also stumped by this magic, but it was not so much stumped by the magic array as by mathematics. Although he knew Muggles far better than anyone else, and even knew the principles of incandescent lamps, he made a light extinguisher for this purpose. But he certainly didn't have an in-depth understanding of Muggle mathematics, and the wizarding world only had arithmetic divination linked to mathematics a little, but it was all fragmented and fragmentary.

"Oh, by the way, I'm going to take care of the trolls, you sit here for a while, I'll be back soon, if you want anything to eat, you can ring the bell here, and the elves will bring it to you." With that, Dumbledore got up and left, leaving Seamus alone in the Headmaster's room.

Seamus didn't know what to do for a while, and chatted with the portraits of the principals while strolling around casually.
