When Ivan saw Sirius's expression, he understood his thoughts and spoke. "The people I need to deal with are all dark wizards, don't tell me you've never killed..."

As a former core member of the Order of the Phoenix, Sirius certainly couldn't have killed the Dark Wizards, on the contrary, there were not a few Death Eaters who died at his hands in the last wizarding war.

But that doesn't mean he'll help Ivan kill at will, Sirius stared at Ivan for a moment, then suddenly asked out loud.

"Can you tell me, your name?"

"Ivan Hals!" Ivan felt that there was no need to hide it, so he said casually.

Hals?! Sirius faintly felt a little familiar, and then his mind moved, could it be that Hals?

Sirius, however, looked at Dobby and wondered, if he remembered correctly, they probably didn't have house-elves in their house.

Grunt...

In the silence of the two, a sound came,

Ivan turned his head to look at Sirius, and the sound came from him.

Sirius was very embarrassed, since he escaped from Azkaban, he hadn't eaten much, and he had consumed a lot of physical strength, of course, he was hungry.

"Dobby, get him some food!" Ivan spoke.

Dobby glanced at Sirius unhappily, after all, Sirius had just attempted to attack his new master twice in a row.

Dobby complied, though, snapped his fingers and disappeared.

A moment later, when it returned, it had an extra plate in its hand, on which were steaks, crème brûlée, nachos, and other foods.

As for the source of these foods...

From Hogwarts, of course... When Dobby went to the kitchen, he happened to see this plate full of food.

Maybe this is some Whitebeard Headmaster's dinner?

Who knows?

Sirius was not polite, grabbed a piece of steak and stuffed it into his mouth, the juice splashed under the bite, and the eating appearance was very ugly.

Ivan opened a thick encyclopedia of potion materials, turned his head to continue his research, and prepared to prepare a true potion.

After all, he doesn't know how to dementor souls, so in order to ensure that he can ask for accurate information from some insiders in the future, he naturally needs to make some preparations.

Fortunately, the method of making the truth elixir was something he had seen in the book "Powerful Elixir" in the forbidden book area.

It's just that the difficulty of configuration is relatively high, and it can't be used before, so Ivan is making this potion for the first time.

Sirius on the other side kept looking at Ivan while filling his stomach.

After eating and drinking enough, and feeling the stiffness in his body completely disappear, Sirius put down the plate in his hand, wiped the oil stains from the corners of his mouth, hesitated, and asked.

"Hals, can you tell me who your parents are?"

"That's not something you should ask!" Ivan glanced at him.

"Not necessarily, if nothing else, I probably know your father!" Sirius raised an eyebrow and said tentatively.

"I guess you're supposed to be a child of a single-parent family, aren't you?"

Hearing this, Ivan paused in the action of configuring the truth elixir, but did not reply.

Sirius noticed this keenly, and with a clear understanding of it, he moved on.

"That's right, your father and I used to work together, we were very good friends at the time, and we fought the Death Eaters together..."

"He is a very brave man, a well-deserved hero, always fighting on the front line, and together we have thwarted many of the Dark Lord's plots..."

Sirius gushed about the events of thirteen years ago, intending to bring them closer, but Ivan interrupted him impatiently.

"But he died in the end, didn't he?"

Sirius's expression froze, and he wanted to correct Ivan's words, because in his opinion, Ivan's father was a heroic sacrifice, a great one!

However, Ivan didn't give him this chance, and before Sirius could speak, he continued in an aggravated tone.

"If I'm not mistaken, his death has something to do with Dumbledore?"

Sirius was completely stunned, he looked at Ivan in a daze, and then said angrily.

"That's what your mother taught you? I knew she was a selfish and snarky person! A dark wizard through and through! Your father must have been blind to fall in love with her..."

"More than ten years ago, she has been trying to prevent your father from joining the Order of the Phoenix, constantly instigating him to leave everyone behind and flee to the Americas at the most dangerous time, and even secretly stumbling in secret, none of your father's friends, including me, can afford her!"

Sirius's tone was sharp, and he was so angry that he wanted to curse two more words, when a blinding red light suddenly flew past his cheek, interrupting his words.

A moment later, a huge explosion sounded, creating an additional circular crater in the wall behind.

"Shut up!" Ivan looked at Sirius coldly.

Compared with the plain and masked "hero" father, Ivan trusts Althea more and is willing to stand on Althea's side, so naturally Sirius can't see Sirius sarcastic.

Ivan's overreaction was far beyond Sirius's expectations, and he looked back at the huge crater that had been blown out behind him, and a cold sweat broke out.

If this spell hits directly, you will most likely be seriously injured...

Sirius was silent for a moment, but didn't get angry again.

From Ivan's reaction just now, he sensed something was wrong, and Ivan was alone in this dilapidated house late at night, Sirius lowered his tone and asked softly.

"What about your mother?"

"She's fine... You don't have time to care for yourself as much as you care about yourself. Ivan replied stiffly.

He blocked the news of Althea's death, firstly to confuse the mastermind behind the scenes, so that he could use the compound decoction, and secondly, to avoid causing Althea's social death.

Ivan doesn't know much about the paradox of time, but he understands that if many people know that Aisya is dead, it will definitely not be conducive to him going back in time to save people!

After thinking about it, Ivan turned to Dobby and said.

"Dobby, you're in charge of keeping an eye on Blake, and if he says one more word, you'll use a stun spell to quiet him down."

"Yes, sir!"

Dobby was excited, the index finger of his right hand glowed with magical light, and his two eyes the size of copper bells stared closely at Sirius' every move, and the stun spell was ready to be unleashed.

Under Dobby's watchful eye, Sirius kept his mouth shut in embarrassment, but sighed inwardly, he already had some guesses...
