On the other side, Sirius, who had once again taken the form of Animagus, kept changing his position, sniffing vigorously in the thick mist, and all kinds of scents reached his nose.

However, since there had just been a battle, the air was filled with the smell of burnt wood when the wooden table was burned, and it was not easy to accurately identify the various smells.

"Well, Lupin and Harry are about ten meters behind... Strange, what about Ivan? Sirius muttered to himself, and he ran over to the smell that still lingered in the air, only to find that there was no one here, and could only guess that Ivan might have stayed here.

Just as Sirius hesitated, his hair suddenly exploded, and a warning appeared in his mind.

Without any hesitation, Sirius followed his instincts and rolled forward a few times.

At the same moment, a crimson beam of light flew out from the thick fog on the side and struck where he had been standing, blasting a small crater in the plank.

Sirius's face changed, and before he could breathe a sigh of relief, he saw more beams of light flash out of the fog.

Sirius broke out in a cold sweat and could only run in the opposite direction, changing his position from time to time, trying to shake off Ivan with the help of Animagus's excellent mobility and disappear again in the fog...

To Sirius's surprise, no matter how he changed his position, Ivan would always be the first to find him.

At first, Sirius thought that Ivan was judging by the sound of his running voice, so he simply changed back into his human form and cast a spell to cause some sound to interfere.

But even this didn't help, Ivan was still able to find him as soon as possible, hiding in the thick fog and throwing a few spells.

"This can't be? How the hell did he know where I was? Sirius was exhausted, but couldn't figure it out, and soon couldn't dodge, and was hit head-on by a red beam.

The wand in his hand suddenly came out of his hand, and flew into the mist with a whirl, and his body fell heavily into the pile of debris behind him.

A wooden plaque that fell to the ground next to it was instantly activated into a long rope, which rolled up silently, tying Sirius tightly.

At this time, Ivan came out of the thick fog, stretched out his hand to catch the flying wand, and then looked at Sirius who was tied up and said with a smile.

"Looks like you're losing this time, Sirius!"

"Alright! That's right! Sirius tried to break free, but found that the rope was tightly tied, and noticed that Ivan had been pointing his wand at him, without the slightest slackening, only nodding helplessly.

When Ivan untied him, Sirius grinned and got up from the ground, having endured the battle just now, and now that he had relaxed, he immediately felt the burning pain of the wound.

"Scars heal!" Ivan shook his head and stepped forward to press his wand against his wound, using healing magic.

A green glow flickered at the tip of the wand, and the laceration on the arm soon healed under the influence of magic.

"You even know how to heal magic?" Sirius was surprised, and he really wanted to ask if there was anything that this little wizard wouldn't.

"It's always right to learn more, isn't it?" Ivan explained casually, and suddenly frowned after repairing a few wounds, because some wood chips from the previous battle had been embedded in the wounds and could not be healed directly.

Ivan had no choice but to cast a spell to tear the wound wider, picking out the sharp pieces of wood and gravel...

Sirius inhaled in pain, but when he heard the sound of footsteps getting closer, his face suddenly became very calm, and only the corners of his mouth twitched from time to time, and he could tell that he was enduring the pain.

Ivan looked at Sirius in surprise, and then saw a worried Lupin and Harry running over.

"Sirius! Are you okay? Harry looked at Sirius' arms and chest injuries and hurriedly asked.

"It's okay, it's just some minor injuries, it's normal to get injured in battle!" Sirius waved his hand, pretending not to care, and then his face twitched, but it was Ivan who picked a sharp gravel out of his flesh.

Still, he barely bothered to make a fool of himself in front of Harry.

"You're so adventurous! Do you know what happens if you use that level of magic in a competition? Lupin was a little angry while worried, and couldn't help but reprimand.

The intensity of the battle just now was beyond his expectations, and it could be described as a life-and-death struggle, so when he sensed that the battle was over, he rushed over with Harry as soon as he could.

"Don't say that, Remus! Of course we can control our magic... Isn't that okay? Sirius replied slightly embarrassed.

He had been in Azkaban for more than ten years, and it had been a long time since he had experienced such a hearty battle.

Coupled with Ivan's strength greatly exceeding his expectations, he had to use some powerful magic to increase his chances of victory.

Lupin shook his head helplessly, and didn't mention it again.

"Who won this contest?" Harry on the side asked curiously.

"Sirius, you're not going to lose again, are you?" Lupin looked at the embarrassed Sirius and the neatly dressed Ivan, and even had a guess.

"Yes! As you can see, I lost again! Sirius shrugged helplessly, "By the way, Ivan, how did you determine where I was before?" ”

"It's just a little magic of the detective type!" Ivan explained casually.

In fact, he used bloodline magic to transform into a bat, using ultrasound positioning to determine Sirius' movements.

However, Ivan is not ready to expose his bloodline magic, this battle, he can be said to have gained a lot, while absorbing Sirius's combat skills, Ivan is deeply aware of the importance of hiding hole cards!

His snake eyes and magic ring had only been used a few times in front of Sirius, and Sirius had found a way to target them and restrict them.

And the reason why he was able to easily defeat Sirius was also because of the transformation of the bloodline magic Boggart that was not known to the other party.

It was precisely because it was not clear that Ivan would be able to turn into a bat and locate it with ultrasound that Sirius made the wrong decision to obscure his vision with a dense fog ...

This made Ivan understand a truth, as long as there are enough hole cards, no one can beat him!

Sirius, on the other side, saw that Ivan didn't want to say more, and didn't ask more, and kept his promise and agreed to Ivan's participation in the recovery of Regulus's body.

"What about me?" Harry asked anxiously.

"You'll have to stay home and wait for news from us!" Sirius patted Harry on the shoulder and spoke.

"You can all go together, but I'm the only one who has to stay here and wait for you to come back?!" Harry said reluctantly.

"Harry! This operation is too dangerous to be part of what you students should be involved in. Lupin offered a few words of reassurance, then looked at Ivan again, and spoke again.

"Ivan has proved his strength by defeating Sirius, and when the time comes, it won't hold us back, are you ready to give it a try?"

Lupin said this just to make Harry retreat, but unexpectedly saw Harry nod solemnly.

Sirius's face suddenly darkened, he lost to Ivan, yes, but that didn't mean that his strength was weak, and he had to let Harry know how good he was!

Harry struggled to think about the dueling techniques he had learned in the second-year dueling club, and even agreed on tactics in earnest.

He had heard Professor Flitwick in Charms class say that even the most powerful wizard would lose his wand if he was caught in the Disarming Charm... It's not that you don't have the possibility of victory!

Unfortunately, no amount of thought proved to be able to make up for the gap in strength and combat experience, and after only a few rounds of fighting, Harry was confiscated by Sirius with his wand.

In frustration, Harry gave up the idea of going along.

Ivan on the side looked at Harry, who was easily defeated, and shook his head secretly, if Harry was willing to spend a little more time studying on weekdays, he would not be defeated in three or two clicks.

After all, Harry's foundation is still very good, his talent for protective magic is very high, and the reflexes he has developed as a Quidditch player for many years are also applicable in battle.

After two battles with one defeat and one victory, Sirius also sobered up a lot.

At least not as in the previous hurry, he had to go to the cave and fish out Regulus, but discussed specific countermeasures with Ivan and Luping, and asked Kreacher to buy some potion materials by the way.

It wasn't until evening that the prepared people took the potion they had just brewed and prepared to go.

Lupin suddenly remembered something, and said to everyone with some concern. "There are three of us now, and if we add Regulus, it's four, and if something happens in that cavern, will Kreacher bring us out together?"

Sirius immediately realized this, and immediately looked at Kreacher for an answer.

The old house-elf hesitated, although it was able to escape from the dangerous cave twice in a row, it obviously felt a huge barrier when it cast the teleportation magic, and it consumed a lot more mana than usual.

So if you want to be absolutely safe, I'm afraid you can only take one person at a time, and transfer everyone away in four times.

Thinking of this, Kreacher did not hide anything and told the truth truthfully.

Sirius and Lupin were somewhat worried after listening to Kreacher's story, and the risk of the operation increased considerably.

"Why don't you just call another house-elf over like this?" Ivan didn't feel very safe, thought about it, snapped his fingers, and said hello.

"Dobby!"

As soon as Ivan's words fell, an ugly house-elf with big eyes appeared in the clearing in front of him.

"Dobby is at your service, do you have any orders? Mr! The house-elf said loudly, looked around curiously, and greeted Harry happily.

Harry nodded awkwardly in response, the previous few times he met Dobby didn't make a good impression on him, but instead cheated him several times in his second year, which Harry always remembered.

"That's what Dobby, I want you to go to a place with us, and help Kreacher get us all out if you need to..."Ivan gave a brief introduction to the matter, and as for the more specific, he was ready to explain on the way.

Dobby agreed without hesitation, although it and Ivan are nominally employed, they are actually no different from slaves, the only difference is that they can get a paltry salary every month...

"Is this your house-elf?" Sirius looked at Dobby in surprise.

Generally speaking, only pure-blood wizard families with prominent ancestors can have a house elf, and the Hals family is obviously not one of them.

"No, I hired Dobby, it used to belong to the Malfoy family, but now it's free!" Ivan shook his head and explained.

"Yes, gentlemen, Dobby is now a free elf! The kind Mr. Hals hired Dobby and was willing to pay him a silver sike a week! ”

Dobby said proudly, and turned to look at Ivan again, looking very moved, about to burst into tears, and he continued in a choked voice.

"And sir... Mr. also gave Dobi a day off last year. Oh, my God! Mr. Hals is such a great man! ”

Sirius, Lupin, and Harry all looked at Ivan with a strange gaze, embarrassing him and eager to gag Dobby's mouth with a gag spell.

Dobby's words made Ivan feel like a chow skin, and Dobby was his slave and laborer, and he was grateful to him.

But before Ivan could explain, an angry scream suddenly rang out.

"You're a shame!"

The old house-elf Kreacher shuddered and looked at Dobby angrily, as if he were staring at some enemy.

"Dirty, shitty traitor! You should be ashamed! Qualified house-elves don't need a salary and vacation! No house-elf would turn his back on his master," Kreacher's words were sharp, hoarse and unpleasant.

"Dobby doesn't think so, Dobby is a free house-elf who needs a salary and vacation!" Dobby was not knocked down by Kreacher's words, and spoke to himself.

It had heard similar words at Hogwarts hundreds of times, and it couldn't shake its mind.

Kreacher was so mad that he tried to retort, but Sirius stopped him.

"Enough, Kreacher! Ivan is Dobby's master... Oh, I mean employers, it's a matter between them! Sirius spoke.

Kreacher stopped, but everyone could still faintly hear Kreacher muttering something quietly.
