Just as Ivan was about to return to the Gryffindor common room, he accidentally bumped into Professor McGonagall, who was in charge of patrolling tonight, in the hallway.

"Hals, why are you out there so late? I remember Professor Flitwick reminding you at dinner that it's best for you to stay in your dorm these nights..."

Looking at Ivan, who was running around alone in the castle, Professor McGonagall's face was very serious, and she asked out loud with dissatisfaction.

But I haven't eaten dinner yet... Ivan silently complained in his heart.

He spent the rest of his afternoon and night testing his newfound abilities in the Room of Requirement, except for a meeting with Sirius, and he had no idea what Flitwick had said in the Great Hall at dinner...

It's just that it's not convenient to tell Professor McGonagall about these things, so Ivan hesitated for a moment, and then said apologetically:

"I'm sorry, Professor McGonagall! I'm more used to finding an open place to practice magic after dinner, and today I'm so obsessed with it that I don't notice the time..."

Hearing Ivan say this, Professor McGonagall's serious face suddenly softened a lot.

"Hals, although it's a good habit to take time out to practice magic every day, it's been dangerous outside lately, so you'd better pause for a while, what if Blake is still hiding in the castle and you accidentally bump into it?"

Professor McGonagall spoke earnestly and comforted, and then emphasized the danger of Blake, fearing that Ivan would take his own prowess lightly.

After all, in her opinion, even if Ivan's magic level far surpassed that of his peers, and even reached the level of comparable to that of an adult wizard, he was still a thirteen-year-old child after all, and he was inexperienced in combat, and it was difficult to win against the vicious Sirius-Black.

Ivan didn't mean to refute it, and promised very modestly that he would pay attention next time...

Professor McGonagall nodded in satisfaction, and after a few words, she let Ivan go, and was about to continue her tour of the castle, but before leaving, she suddenly remembered something and hesitated to speak:

"By the way, Hals, remember to go back to the dormitory and persuade Harry not to be too impulsive..."

Harry? What happened to him?

Ivan was confused and wanted to ask Professor McGonagall what had happened.

When he opened his mouth, Ivan stopped again, because he didn't know if he had also said this in the Great Hall, and if he asked by the way, he might reveal that he had been missing for most of the day.

Thinking of this, Ivan casually replied, anyway, he went back to the dormitory and asked Ron and Harry.

"Hey, boy, password!" Walking to the door of Gryffindor's bedroom, a sound of escape rang out.

Ivan looked up to see that the portrait of the fat lady hanging in the doorway was gone, replaced by a portrait of Sir Cadogan and his fat gray horse.

The incident where Blake easily slipped into Gryffindor with a Confusion Charm hit the Fat Lady hard, and although no one blamed her, the Fat Lady blamed herself and insisted that she could not take on the role of goalkeeper.

After the professors failed in persuasion, they had to give the fat lady some time to calm down and replace him with Sir Cadogan, the only willing goalkeeper.

Compared with the dutiful fat lady, the newly appointed Sir Cadogan is not so likable, often teasing others to duel with him, not to mention, and changing passwords is also very diligent.

"It's a cunning liar, right? If you haven't had time to change your password—" Ivan said helplessly.

He had to pray that his luck would be better, or he would have to learn from Blake to cast a confusion spell on the other party.

"Yes, you got it right! Don't forget to be wary of this, get inside! Sir Cadogan mounted his fat horse, brandished his sword, and opened the door.

Ivan breathed a sigh of relief and walked straight into the Gryffindor common room. The flames burned vigorously in the fireplace, the boiling heat extinguished the cold of the night, and the sound of a few young wizards who had not slept could be heard laughing and chasing each other in the lounge.

Ivan deliberately took a few steps closer so that he could hear more clearly.

All kinds of playful laughter continued to reach his ears, and soon, Ivan confirmed that at least in his non-transformation state, laughter had no effect on him...

Ivan was delighted by this discovery, and returned to his bedroom in a happy mood, and as soon as he pushed open the door, he heard Harry and Ron arguing.

"Calm down, Harry! Sooner or later, the Ministry of Magic will catch him, and you don't have to die for it! Ron looked worriedly at Harry beside him and spoke.

However, Harry's face was very ugly, he didn't appreciate it at all, and said hysterically.

"How do you calm me down? They knew why Blake was chasing me, and they kept it from me for so long! Do you know what I see and hear when I encounter Dementors on the train?

I heard my mom screaming and begging Voldemort to spare my life! If you hear your mom screaming before she was killed, you'll want to find the betrayer... Personally revenge! ”

Ron had a helpless expression, but fortunately he heard the movement at the door at this time, turned his head to look at Ivan, and greeted happily. "Ivan, you're here just in time, hurry up and persuade Harry!"

"What's going on?" Ivan was very surprised, and from the words of the two, he guessed a rough idea, but he didn't know if it was right or not.

Ron didn't hide it, explaining the cause and effect.

Ivan then learned that Harry had been haunted by Lupin's mistake last night, and had been pestering professors to inquire about the situation outside of class today.

Despite the tight-mouthed nature of McGonagall and the others, the professors were not the only ones who knew about the situation, and in the end, Harry was able to extract the news from Malfoy's mouth.

The price was that Malfoy taunted him for being a coward who only dared to hide in Hogwarts and didn't dare to seek revenge on Black...

Harry was naturally so angry that he was going to fight Sirius-Black to the death as soon as his brain was hot! Fortunately, Ron grabbed him in time, and Hermione quietly informed Professor McGonagall to stop him.

"You're also going to stop me from going to Black for revenge?" Harry had a cold face, really angry.

However, Ivan shook his head lightly and said, "No, I'm not going to do that!" ”

Harry was stunned, not expecting Ivan to say that.

Ron stared at Ivan with wide eyes, and he suddenly felt that it was a mistake for Ivan to convince Harry...
