Hogwarts Melting Ice Journey

October 24th, Saturday, in an unknown alley.

Sirius changed from his Animagus form back to human form in a deserted corner. He and he had just been attacked. Fortunately, he escaped from the Death Eaters by turning into Animagus.

Sirius took out a bottle of fresh juice and sprinkled it on his injured shoulder, then listened to the movement around him.

"I sensed his scent." It was Greyback's voice. Sirius was attacked by him and his werewolves just now.

"Damn it." Sirius looked around and saw a group of stray dogs around. He jumped into a black dog and blended in.

An hour later, Sirius walked into James' home. He looked very bad, pale and out of breath.

"Sirius, what's wrong with you Lily, please find the white blood." James saw Sirius coming in and hurriedly got up and helped him sit on the sofa. Lily found the white blood and the healing potion from a drawer and handed it to Xiao Sirius.

After a while, Sirius's condition seemed much better, at least he was no longer as pale as before.

"Sirius, what happened" James asked after seeing that Sirius was feeling better.

"I was attacked by Greyback and his minions, and I also met many Death Eaters during my escape. They seemed to know my route and attacked me exactly where I thought it was the safest place." Sirius took Lily He handed him the black tea, took a sip and said.

"It's that traitor again." James punched the table. "He has already killed many members of the Order of the Phoenix."

"Listen to me, James." Sirius felt that it would be too late if he didn't change the secret keeper. "The traitor obviously knows my whereabouts. If I continue to serve as the secret keeper, it will be easy to expose your position. You must know the traitor He is also a member of the Order of the Phoenix, and he most likely knows where you live. Once I die, you will be in danger."

James thought about it and said, "Sirius, I believe in your strength and your loyalty to your friends. I know you well."

"James, this is not a matter of trust." Sirius interrupted James, "I understand your trust in me, but I also have to be responsible for you. If I continue to be the secret keeper, it will put you in crisis. Yes. And you must be prepared that I won’t be able to keep it secret.”

Sirius' face was undoubtedly very ugly when he said the last words, but he had to prepare for the worst.

James looked at Sirius, and after a while he said, "Then who do you think is the most suitable?"

"Peter Pettigrew." Sirius spit out a name, "I think Remus is not suitable because of his special status and because he has been very close to those werewolves recently."

James didn't object to him out loud, but just nodded.

"Then how are you sure Peter won't betray?" Lily asked Sirius.

Sirius looked at Lily, "It's impossible for him to betray us. You have to know that he has been with us all the time in school and always agrees with our views. He admires us very much. To say whether he will betray us, Xiao Dwarf stars definitely count as one."

"Lily, I also believe in Pettigrew. He is a very loyal friend to us." James agreed with Sirius's point of view.

Seeing that both of them thought Pettigrew was the most suitable, Lily no longer questioned their decision.

"I'm going to find Pettigrew now." Sirius was always like that, once he decided to do something, he would do it immediately.

"Wait, Sirius, don't we tell Dumbledore?" Lily stopped him.

"The fewer people who know about this matter, the better. This will have the best effect, right?" Sirius said, and then walked out of the Potter family's house.

In the Room of Requirement, Stephen and Penny were practicing magic spells, while Martin sat aside and watched them practice.

Stephen flicked off Petunia's wand with his wand, then turned back and cast a disarming spell on her. The spell flicked off Petunia's wand, and Stephen reached out and grabbed Petunia's wand.

"Penny, your spell casting speed is still slow." Stephen walked over and returned the wand to Penny. "And the power is not strong, so the spell cannot fly fast enough."

He turned to look at Martin and waved to him. Martin got up from the sofa and walked next to Stephen.

"Martin and I will demonstrate. You watch our movements carefully."

"I know, I'll try my best to see clearly." Penny nodded and walked to the sofa.

"Martin, don't speed." Stephen hit the road limit first. If Martin speeded up, he wouldn't be able to hit him at all.

"I'll try my best." Martin walked to a suitable distance from Stephen, took out his wand and pointed at each other with Stephen.

Stephen waved the wand at Martin, but nothing happened. Martin smiled and suddenly disappeared in front of Stephen.

"Here we go again." Stephen was a little helpless, "Martin, how can Penny see you clearly like this?"

Stephen casually made a large puddle of water on the ground, and then turned the water on the ground into ice, and Martin had to reveal his figure.

"Expelliarmus" Stephen predicted Martin's movement direction and used the disarming spell, but Martin reacted quickly and blocked the disarming spell with the armor spell.

"Expelliarmus" This time Stephen's beam was thicker and faster. It penetrated Martin's armor spell and flicked his wand in the direction of Stephen.

"Do you see clearly, Petunia?" Stephen waved his wand to make the ice on the ground disappear, and then walked to the sofa with Martin and sat down.

Penny nodded, "I think you can see it clearly, but can you explain what you just did?"

Martin explained: "Compared to Stephen, my advantage lies in my movement speed, so I can only find Stephen's flaws by moving at high speed. You must know that the magic power he can use at one time is much stronger than mine. If he casts spells at the same time, I will be very vulnerable." It’s hard to keep fighting him.”

"So the most important thing for me is to limit Martin's speed." Stephen added after Martin's words, "So either force him to stop or help him speed up."

"So you added a layer of ice to the ground." Penny understood, "But why not just create ice directly, but use the water creation spell first?"

Stephen shrugged helplessly, "Because I don't know how. It would obviously be much more convenient if we could make ice directly. Martin also released water just now. He could start interrupting me when I was using the clear water... .”

......

The three of them were exchanging skills in using magic spells in the Room of Requirement, and Stephen took a moment to look at the time.

"Maybe I should try to tell Dumbledore about Sirius and James changing the Secret Keeper. I don't know if it's too late." Stephen thought to himself. He thought he should write a letter to Dumbledore. As for the signature, he didn't think it was necessary to write it. Dumbledore would probably check it himself.
