Became good friends with the Boy Who Lived

Throughout lunch, Harry and Ron were discussing how to deal with Draco. "We only know the Disarming Charm. What should we do after we knock their wands away?" Harry asked worriedly.

"Don't worry, don't worry," said Ron heartlessly. "They probably don't even know how to Disarm. Just knock their wands away and then you punch Malfoy in the nose..."

It was midnight, and Aeris was still in the common room reading a book he had borrowed from the school library, "Summoning Array and Summoning Techniques". Aeris found the book in a corner of the library, on the edge of the restricted area.

Harry and Ron were about to leave for the trophy room to keep their appointment. Harry asked Aris, "Aris, you really aren't going with us?"

Edwards took his eyes off the book and said, "If the three of us go together, we will be too conspicuous and easily discovered by Mr. Filch or Mrs. Norris (Mr. Filch's cat). Take my advice... Harry, there is a high possibility that Draco will not go, and you may come up empty-handed..."

"But I have to go," Harry said stubbornly, "If he goes and I don't, he'll laugh at me for the whole semester."

Aeris sighed and said, "Then I'll wait here for you to come back." Then he turned his attention back to the book.

About an hour later, Aris, who was immersed in a book, heard some movement coming from the entrance of the cave. Harry climbed in first, followed by Ron, Hermione and Neville.

Aris said in a strange tone: "It seems that there are spectators for this midnight duel. How is it? Brothers, did you win?" Ron collapsed in an armchair and said with lingering fear: "It's hard to put it into words!"

Harry, who was also sitting in an armchair, said quietly, "You're right, Aris, Malfoy didn't show up."

Hermione glared at Harry and Ron fiercely, and said in an unhappy tone: "I advised you, now I'm going to go back to sleep before you kill me or expel me, hum!" After that, she turned around and went back to her dormitory.

"What's wrong with her?" said Ron angrily. "We didn't ask her to come with us!"

"Thank you for your help in the flying lesson, Aeris." Neville also said with a bitter face. Aeris said, "You're welcome, Neville. Are you okay? Why do you look so bad?"

Neville smiled bitterly and said, "Let Harry and the others talk to you. I'm really sleepy. Good night, everyone!" After that, Neville returned to the dormitory.

"So," Aris groaned, "what happened?" Harry recounted their experiences to Aris, with Ron adding a few words from time to time.

Aris said, "You were forced by Mr. Filch into the restricted area on the fourth floor, and you entered the corridor that Professor Dumbledore forbade you to enter, and you saw a big dog with three heads?"

"Well, Hermione also noticed that the big dog was guarding something," said Harry.

Aeris thought for a while and said, "You once said that you and Hagrid took something out of Gringotts. After you took it out, the invasion of Gringotts was on the front page of the Daily Prophet. Then I will make a bold guess that Professor Dumbledore deposited something important in Gringotts, but such an important thing was also coveted by someone. He was worried, so he asked Hagrid to take it out of Gringotts and kept it in the safer Hogwarts, so..."

"That big dog is guarding something like that!" Harry said first. Aeris nodded and said, "These are just our guesses. No matter what the big dog is guarding, it is not something that we little wizards can worry about."

The next day, when Draco saw the three people coming to the restaurant, his pale face immediately became gloomy. He seemed to want to mock Harry and deliberately brushed past Harry and the others. Before he could open his mouth, Harry growled, "Coward!"

This sentence silenced Draco, and Aeris felt that Draco's face became even gloomier.

Draco snorted indignantly and walked towards the Slytherin table.
