Thinking of this, Ivan couldn't help but get excited, but he still needed to do a rehearsal in advance to determine if it was feasible.

"Scars heal!" Ivan tentatively held his wand against Kelly's bloody back, and healed her wounds with a healing spell, trying to restore what he had done that day.

The magic soon kicked in, and the wound on Kelly's back healed...

Sirius was very puzzled to watch Ivan's strange behavior, treating a dead man? Why? Is there any special significance?

Ivan slowly breathed a sigh of relief as he healed his wounds, and things were exactly as he expected.

But the next moment, Ivan's pupils shrank and froze in place.

The female corpse in front of her suddenly returned to its original appearance, and the effect of the compound decoction disappeared...

"Impossible, could it be that you drank too little potion?" Ivan frowned, staring blankly at Kelly who had changed back to her original form.

Dead people don't drink potions, and Ivan was only able to let go of Kelly's corpse and set his sights on the other three black-robed wizards.

Luckily, he still has three test subjects...

After pouring a compound decoction for the three of them and recording the data in batches, Ivan discovered a problem.

After death, the effects of the Polyjuice decoction, while still retaining, become very unstable, have a greatly reduced duration, and are extremely susceptible.

The healing spell he used undoubtedly upset this balance, and once he healed the wound, no matter how many doses of the polyjuice decoction the other person had taken before, it would be lifted in a very short time...

When the last black-robed wizard turned back to his body and fell to the ground, Ivan's face became worse and worse.

"What the hell is going on?"

Ivan was completely confused, if the healing magic would affect the effect of the compound potion, then when he used the healing magic to heal "Althea" before, why was the corpse not affected in the slightest?

Or did he go back in time and didn't use a polyjuice decoction? Did you use something else?

Ivan looked at the four corpses in the ground and pondered for a long time.

When he was ready to use a time turner to change the past, Ivan had considered various options.

One of the more reliable is to use Transfiguration or Polyjuice decoction to create a fake corpse.

After all, he had seen Althea's corpse with his own eyes, and had taken the corpse to Doggett to confirm his death, so this step was essential.

At first, Ivan tried to use Transfiguration, but after experimenting with it himself, he abandoned this plan.

A level 5 Transfiguration Charm is not a perfect replica of a wizard, let alone a copy that can be injured and healed.

This is simply not possible, so the compound decoction becomes the only possibility.

Ivan believed in this before, so he asked Dobby to buy a lot of books related to potions to confirm the possibility of this plan.

I didn't expect a problem on the last step...

Ivan's uncertain face was seen in Sirius' eyes.

Although he didn't know why Ivan did such a strange thing to these black-robed wizards, he could see that it might be verifying something, and the result might have deviated from Ivan's imagination.

He was no longer silent, and before Ivan could get into the horns, he changed the subject.

"Hals, didn't you say you were going to check on that Borgin Bock magic shop? When do we start moving. ”

"Now, of course!" Ivan exhaled deeply, came back to his senses, and said without hesitation.

He'd at least confirmed that it wasn't Althea who died...

The way to replace the corpse, he still has some time to think slowly...

Ivan turned his head, ready to let Dobby take him to the Boggin Bock store with a shapeshifter, but closed his mouth again when he noticed the tired look on Dobby's face.

Not long ago, Dobby frequently used shapeshifting to transfer the six of them to this temporary stronghold, and Ivan didn't want to squeeze this house-elf too much.

So, Ivan instructed Dobby to guard the stronghold and dispose of the corpse, and he changed his body, gradually shrinking into a gray-white owl, flapping his wings and flying out of the window.

Sirius shook his head, transforming into an Animagus form and following suit.

......

Gray-and-white owls flutter their wings in the night sky, and a pair of eagle eyes scan the streets below.

Perhaps due to the attack a few days ago, a large number of shops closed their doors and windows early, and there were not many wizards in the alleys.

Ivan's chosen temporary base was on the west side of Tumbledown Alley, some distance from the Boginbock store.

After about fifteen minutes, Ivan stopped near the Boginbock store, thinking about how to get in.

The doors and windows of the shop were locked, and the only good thing was that there were no Auror seals and no patrols.

Ivan suspects that this may have something to do with the fact that Bock has not yet been determined to be dead...

Because of this, Ivan was very vigilant, and slowly flew in through the chimney above, and then returned to human form in the fireplace.

Inside, it looked hollow and dark, and a large number of shelves could be vaguely seen neatly arranged, no different from the last time I came.

"Fluorescent flicker!" Ivan waved his wand and released the Light Charm,

When he got closer, Ivan realized that all the shelves were empty, and everything that had been placed on them was gone.

It is unknown if it was confiscated by the Ministry of Magic as an illegal item, or if it was transferred to another place by Bock.

And to Ivan's surprise, it didn't look like a battlefield where a fierce battle took place.

Is it because of the Regeneration Charm?

Ivan thought to himself.

After carefully inspecting the floor and shelves, Ivan did find some traces of battle, and the restoration spell was not omnipotent, and the effects of some powerful spells were not so easy to eliminate.

Bang~

Just as Ivan was thinking, a crisp sound came from the side, and Ivan waved his wand at the other party, only to realize that it was a black dog jumping in through the broken window.

"How's it going, Hals? Did you find any clues? Sirius quickly reverted back to his original form and asked.

"Not yet—" Ivan shook his head helplessly.

"Anyway, let's search this place first." Ivan glanced around at the dark magic shop.

He had a hunch that he might be fighting the other side here when he returned, so it was important to familiarize himself with the terrain in advance...
