Harry Potter and the Great Old Ones

Chapter 207 Trading
Sirius turned to try and escape into the Gryffindor Tower, but in the blink of an eye he appeared at the entrance to the common room.

Sirius tried to run out the window again—

But before he could even touch the window, he crashed through the wall opposite the window and landed on the ground—

After that, Sirius tried many other routes, but he was unable to escape the Gryffindor common room.

"Let me go!" Sirius Black transformed back into human form and threatened Tyella, "I know you're Harry's good friend, and I don't want to hurt you!"

“I don’t want to hurt you either,” Tierra said. “Come, sit down. I just want to talk to you—”

"Petrify them all!" Tiera said, waving her hand.

Sirius Black pounced on Tiara before she could finish speaking, so Tiara could only wave her hand.

Sirius Black fell hard to the ground.

Tierra waved her hand again, and Sirius floated lightly onto the sofa next to her.

“I don’t want to hurt you, or use you for a reward, Mr. Black.” Tierra waved her hand, releasing Sirius’s petrification. “I just want to make a deal with you.”

"Silent and wandless spellcasting?" Sirius exclaimed in shock. "Who are you? No third-year wizard could do that!"

“Times are changing, Mr. Black,” Tierra said. “I know you Raiders are the elite of the last era, but the English magical world is full of talent. You’ve been in Azkaban for so long that you don’t know that it’s not uncommon for third-year students to be able to cast spells silently and without a wand.”

"You know about the Raiders?" Sirius asked again.

“I know everything,” Tiera said, tapping her golden right eye. “I know Moonface is Lupin the werewolf, Bigfoot is Sirius Black, and you are an Animagus who can turn into a big black dog. I know Pike is James Porter, and his Animagus is Stag. I also know that Wormtail, who faked his death to frame you, is an Animagus who can turn into a mouse. I know everything, Mr. Black. Your past, present, and future are just different chapters in a book to me.”

"You are a prophet... no, you are a prophet!" Sirius Black almost shouted. "You are a prophet!"

“The real deal,” Tierra said. “I was Harry’s classmate and a good brother who slept in the same bed.”

"Harry, Harry, he..." Sirius Black tensed up the moment he heard Harry's name.

“Harry is doing well, his life is happy and fulfilling, his studies are going well, but… he has only one problem,” Tierra said. “You.”

“Harry thought you were there to kill him,” Tierra added.

"That's good...that's good...How could I, how could I kill him? He's James's child, those damned idiots at the Ministry of Magic! James and Lily are my good friends, I have never betrayed them, I haven't!"

“Hehe, don’t get excited, Mr. Black, I believe you,” Tyella comforted. “That’s why I’m talking to you here instead of taking you to the Ministry of Magic for a reward.”

"What do you want?" Sirius asked.

“I want a deal,” Tierra said.

"trade?"

“Yes, a deal.” Tierra stretched out his hand and grabbed at the air—

Tiera retrieved a palm-sized vial from the void before her, then drew her wand and placed it on the coffee table.

“I offer you a deal, Mr. Black.” Tierra placed the medicine bottle beside Sirius. “This contains a Polyjuice Potion infused with my blood. If you drink it sparingly, this dose should be enough for you to transform for a month. After a month, I will brew a new Polyjuice Potion for you.”

"What do you mean?" Although Blake already had a guess in his mind, he did not reach out to take the bottle of compound decoction.
"As I said, it's a deal. Before Christmas, I can give you my identity, and you can pretend to be me, stay here, stay by Harry's side, protect James and Lily's child, walk around Hogwarts as a free man, freely search for Peter Pettigrew, and even relive your school days."

"And what's the price?" Sirius asked excitedly. "What is the price?"

“A third of the Black family’s property, and…” Tierra said, “and you must take me to the Black family’s old house during the Christmas holidays, you must take me to number twelve Grimmauld Place, and then allow me to take something from there.”

"That's it?" Sirius was a little surprised. "You could have taken all the property, a third of it, and a magical item from Black's old house? This is too cheap. You could have taken it all."

Look at this, look at this, this is what happens when someone gets sold out and still helps count the money.

Look, he helps me with my classes, does my homework, and even pays me.

After I catch Peter Pettigrew, he'll have to thank me.

For a fleeting moment, Tierra found Sirius much more pleasing to the eye.

"Yes, I hope you can help me with all my assignments and classes while you're pretending to be me."

"So it seems you're not a very studious student. Okay, I agree to that too," Sirius said.

"Also, I hope you can try to control your impulses and not reveal your identity, at least not let too many people suspect that I am not who I am." "Of course, I would have agreed even if you hadn't said so," Sirius said, "but..."

“But you’re worried about Snape, aren’t you?” Tierra said. “Severus Snape, that snotty-nosed slut, dreams of catching you and handing you over to the Dementors.”

“Yes,” Sirius said, “Snotty is awful, but I have to admit he has a very keen sense of things. Once he notices even the slightest thing about you—”

“He won’t,” Tyella interrupted with a smile. “I can assure you of that. Even if he suspects Sirius Black has infiltrated Hogwarts disguised as a student, Tyella will be the last person he tests.”

"And your other friends..." Sirius Black asked again.

"You don't need to worry about that. With everyone except Harry, Ron, and Hermione, you just need to act aloof, and they won't bother you," Tierra said. "As for Hermione... our little witch is too busy right now to pay any attention to me. With Ron, you just need to keep feeding him. As for Harry..."

“As for Harry, as long as you get closer to him, help him with his homework, and encourage him often, I guarantee he will ignore any suspicious things about you,” Tierra said.

"What about the other teachers?" Sirius Black asked again.

“I’ve basically offended all the other teachers,” Tierra said. “They’re avoiding me now.”

“You knew all along,” Sirius said. “You knew I would escape, you knew I would come to Gryffindor Tower to search for Peter Pettigrew, you had already set a trap, hadn’t you?”

“Yes, after all…” Tiera said, pointing to her right eye, “I am a prophet.”

"Then you should know that Aurors are already lying in ambush at Grimmauld Place. As soon as I show myself—"

“You don’t need to worry about that,” Tiera said. “Just take me there, I’ll handle the Aurors.”

"Heh." Sirius chuckled. "You're too young. Don't think you can handle this just because you know a few silent, staff-less spells..."

“That’s my problem,” Tiera said. “Mr. Black, you’ve been in Azkaban for too long, you’ve been out of touch with society for too long, you don’t know what kind of feats third-year students can accomplish these days.”

"But I still don't believe it..."

“We can sign an unbreakable spell,” Tiera said. “I can assure you, I can get you out of here unscathed.”

“Okay,” Sirius Black said resolutely, “I accept your deal.”

“Very good.” Tierra said with a smile, then extended her hand—

A wisp of golden flame ignited in Tiera's palm.

Sirius Black looked at the cluster of flames in shock, then at Tiera's gentle smile, and then resolutely covered it with his palm.

“Would you be willing to provide me with the compound decoction and your identity?” Blake asked.

“I do,” Tiera replied, and a golden flame coiled around her wrist, transforming into a thin golden thread.

“Would you be willing to give me one-third of the Black family’s fortune?” Tierra asked.

“I do,” Blake said.

"Would you be willing to take me to number twelve Grimmauld Place during the Christmas holidays this year, lead me into the old Black family mansion, and let me take one thing?" Tierra asked.

“I do,” Sirius Black said.
Another golden light wrapped around his hand.

"If anything were to happen to me during our trip to Grimmauld Place, would you be willing to protect me from being discovered by the Aurors?" Sirius Black asked.

“I do,” Tierra said.

The golden light wrapped around his wrist again.

"Are you willing to restrain your impulses as much as possible while you are impersonating me, not arouse suspicion, study hard, complete every class and assignment for me with the best grades, and take my final exams with the best possible results?"

“I do,” Blake said.

The final golden light wrapped around their hands.

“Very good, the contract is complete,” Tiera said, withdrawing her hand.
