The train slowed down and was about to enter the platform, except for Allen, who used illusion on his mage robes, and the girls all took off their wizard robes and changed into normal summer clothes. Finally, the train stopped at platform 9 at King's Cross Station. Alan and the others followed the surging people down the train, and when the adult wizards continued to take the initiative to greet the new savior in a friendly manner, suddenly Crook Hill jumped out of Hermione's arms and swooped out, and Hermione, who was a little surprised, hurriedly chased Crook Hill behind, and Alan and the others also followed.

Not far away, after saying goodbye to the Weasleys, Harry was talking to Sirius Black, who had come to pick him up, and Sirius took Harry's luggage and looked very happy. Crookshank leaped to his feet and leaped into Sirius's arms, knocking him back two steps with his fat build, which had recovered quite strongly.

"Crook Hill. Sirius exclaimed excitedly, and stroked it with both hands.

Hermione, too, finally made their way through the bustling crowd and rushed in front of him.

Seeing this, Hermione stopped, after all, Crookshank and Sirius had cultivated a comrade-in-arms friendship, and Crookshank even helped Sirius and Alan in a fight.

Sirius kept stroking the smooth fur of Crook Hill and said with emotion, "This cat is not young. He returned Crook Hill to Hermione, and Hermione smiled: "Indeed, it is about sixteen or seventeen years old, and if it is an ordinary domestic cat, it is definitely not in such a good state, if it is a Muggle cat or something, the life span will be even shorter, and my Crook Hill will obviously live a long time......"

Sirius turned to say hello to Allen, but suddenly spotted Helena floating behind Luna.

"My Merlin, how did Lady Grey come after you, and how did you get her out of Hogwarts?" Sirius, a Gryffindor graduate, exclaimed exaggeratedly, and then leaned into Alan's ear in what he thought was a muffled voice, "Is that rumor true?"

Alan didn't answer Sirius's reckless question, but said to Sirius in a relaxed tone, "Sirius, I have a good deal for you. ”

"What's the deal?" Sirius asked suspiciously, "as long as no one else is involved, there is anything else in my house that you want, you just say it, you helped Harry in this Ministry of Magic incident, and I haven't thanked you properly." ”

"How's Chemley?" Alan questioned Sirius, he still didn't know if Dumbledore had told Sirius about it in the past few days, but since Sirius hadn't had an accident, Dumbledore might not have had time to deal with Voldemort's return with the pure-blood family and the Ministry of Magic and the International Federation of Wizards these days.

"That filthy old thing, stay at home, you want it?" Sirius's gaze swept over Hermione behind Allen, showing a look of surprise, he listened to Harry's words about Dobby and Hermione's attitude towards promoting the emancipation of house-elves, in Sirius's eyes, Kreacher undoubtedly became a tool for Allen to please girls, but thinking of Granger's origins, Blake still persuaded bitterly, " Alan, of course I'd like to give it to you, I'd long ago want to get rid of it, but this old guy was too badly influenced by my mother...... Not very suitable for He...... I think you know what I mean, and even I suspect that purebloods in general are not taken seriously by it......"

"We have recently found some clues about the disappearance of Mr. Regulus Actulus Black. Knowing that Chekley was still there, Allen felt that the plan that he had improvised after seeing Sirius just now could be carried out, so he released the fierce news directly to Blake.

"My brother, Regulus, isn't this stupid idiot long dead?" Sirius's gaze sharpened, although Sirius felt that Regulus was a hopeless bastard, but after all, he was his own blood relative, compared to getting news of Regulus, it didn't matter if Kreacher would hurt the Muggle-born Hermione, and Alan also had the means to make it soft.

"Yes, I'm sorry, Mr. Regulus Black is dead, but we've found out a few things about your brother, and we shouldn't be able to find his body. Alan said unhurriedly, "All you have to do is make sure that Chekley is alive and well in your house until we investigate it, you know, and I've heard Harry talk about how you and it have a mutual ...... Bad relationship. ”

"You can go and get it now. However, Sirius was suddenly startled and made a request: "Mr. Alan, Mr. Harris, I can make a deal with you, but only if we make an unbreakable oath, you must promise that you will never ask Kreacher anything about the Order of the Phoenix, and you will not use magic to forcibly find out about this!"

"No problem, but I prefer fair trade, and I'll get it back when I'm done with my part, but it's more convenient to use the contract and not have to find a witness. As Alan's words fell, a piece of parchment rushed out of Alan's waist bag and was suspended in mid-air, Eren glanced at the wizards around him who were watching because of the vision, and his expression became a little coquettish, and he threw a raven quill pen to Sirius, and after letting his finger burst into flames, he began to write in Latin on it, which successfully caused a burst of exclamations from the wizards around him.

Unlike the one signed by William the Conqueror, the parchment did not have the initials or frames painted with ornamentation, it was just a very simple contract.

"The Devil's Pact!" As the Blake family's former collection, Sirius knew the power of the Devil's Pact.

"Don't worry, I think you should be familiar with this even if you don't know how to use it, I didn't do anything extra, after I gave you the news of Regulus, you gave me Chekley, I just hope that you can keep Chekli safe during this time - of course he is very old, even if he dies of natural causes, I will give you the same news if I find out, I just want to make sure that you and your members of the Order of the Phoenix will not harm him, it is said that your attitude towards it is not good......"

"I'm fine, what to do with that. Sirius cursed, and Alan handed the devil's contract to Sirius, who suspiciously looked at the contract in his hand word for word, and looked at it carefully for a long time, for fear of falling into the devil's trap.

Alan folded his arms around his chest so that he could look at him for a long time: "If I really want to do anything to you, I need to go to such trouble?"

Eventually, the desire for news of his brother Regulus overwhelmed everything, and Sirius signed his name to the devil's pact with a stroke of his pen. After signing, the contract automatically flew back to Alan, who looked at Sirius's full name on the contract, nodded in satisfaction, and added his full name as well, and then put it in his pocket.

At the moment when Eren finished signing, the power of the contract made Sirius understand all the terms of the contract paper, Sirius nodded with satisfaction, and sure enough, Alan did not hide anything from the terms, just asked him to take good care of Kreacher and not hurt him at any time.

Although he really hated this house-elf, but not to the point of harming it at will, Sirius was a little aggrieved for a while, "I'm not a sadist, I've never abused it, it's just that it doesn't take good care of itself, how can a house-elf be sloppy like that." ”

Then, it took a long time for Alan and the others to all walk out of the platform. A shriveled old guard stood guard at the partition wall, allowing only two or three people to pass through at a time, so that they would not burst out of the solid wall at the same time and attract the attention of the Muggles.

"Alan, Helena can't apparition, you guys come with me. Hermione advised, "We need to hurry, Mom and Dad must have been waiting for a long time, they always come early to wait." ”

"If only I had known that when I was in school, I would use Barrow to test whether the Otherworldly Gate would cause danger and damage to disembodied ghosts...... I'll send a message home first. Alan nodded, and a shadow crow appeared in his hand, and after Alan explained that he had brought Helena back and that he could only return later by car, the shadow crow flapped its wings and disappeared from Alan's eyes.
