The Little Superman of Hogwarts

After returning to the castle from the Black Lake, Cree threw himself into the library, desperately searching for secret methods and spells.

If he wasn't mistaken, what the enemy was doing was actually a kind of lich-like operation.

A lich is a spellcaster who uses magic to achieve immortality, transforming into an undead creature through dark magic and necromancy, storing their soul in a phylactery.

In the world of Harry Potter, there is no such thing as necromancy, but they do have dark magic. To a certain extent, dark magic alone can accomplish the transformation into an undead creature.

Finally, in the restricted section of the Dark Arts area, he found an entry.

Soul Parasitism—changing one's soul into the form of a parasite, thereby parasitizing different animals or humans. [Soul Parasitism: The user needs to kill an animal or a person, using the soul of the other creature as glue to adhere their own soul to the other animal or the parasitized object.]

When he saw this term, Cree instantly understood that the person causing chaos at Hogwarts was none other than Voldemort!

A soul body that likes to parasitize others, understands profound magic, and possesses magical tools... Besides Voldemort, Cree felt it was absolutely impossible for there to be a second person. You have to know that the magical world of London, England, including magical creatures, has a total of about 20,000 people, and purely wizards only number six or seven thousand. It's impossible to find a second person among these six or seven thousand who completely matches Voldemort's characteristics.

This probability is even smaller than Mars colliding with Earth. Therefore, Cree judged that Voldemort must have done these things.

"Voldemort, Voldemort! I originally wanted to spare your dog's life and let you continue acting on the stage, but now it seems that it's better for you to die sooner rather than later!" Cree said to himself.

Voldemort used this magic when he parasitized Quirrell's neck, and throughout the entire Harry Potter series, this spell is so difficult to learn and comes at such a high price that no one else can accomplish it.

Voldemort's soul fragment parasitized a merman.

It was precisely because the mermen possessed certain unique imitative magic belonging to their race, allowing them to merge with water, that Cree couldn't detect anything amiss. Furthermore, the opponent used a time-turner-like device, making Voldemort's escape even smoother.

Cree guessed that Voldemort's escape method was like this:

Voldemort's soul first found a mermaid. He killed the mermaid and parasitized it. At this time, the mermaid's body had not completely died and could still maintain magic and activity for several days.

Then, he followed the waterway connecting the Black Lake and the Forbidden Forest, tracing upstream.

He first killed a unicorn and used the unicorn's blood again to replenish his soul. Then, he killed some magical creatures to replenish his magic consumption. When the mermaid's body lost its function, he would smash the corpse to pieces and scatter it back into the Black Lake.

Then, he would once again kidnap a member of the merman race as a sacrifice, precisely because the mermaid's corpse would lose its activity after a few days, so he constantly kidnapped the merman race.

And the reason for his escape should be similar to what Cree guessed: he possessed a time-turner or a similar device.

In the original timeline, Cree should have used his super hearing or super smell to find Voldemort hiding in the dark. But Voldemort activated this magical thing, instantly reversing a few minutes, or even an hour. The original timeline was thus annihilated.

At this time, Voldemort would calmly turn into water and mix into the river, then flow from the river into the Black Lake.

When the Cree of this timeline arrived at Voldemort's previous location, Voldemort had already disappeared.

The Cree of this timeline, which is the current Cree, has still not caught Voldemort.

Although this conjecture has formed a closed loop, there is still no clue on how to capture Voldemort. The time-turner in Voldemort's hand is really a great weapon.

Cree came to the front of the Headmaster's office with his doubts—but Dumbledore was not in the office. Thinking about it carefully, several young wizards have been poisoned one after another these past few days, and even Hagrid was near death, so the pressure from the Board of Governors and the Ministry of Magic must be enormous.

Dumbledore should be in the Ministry of Magic in London, dealing with some interpersonal relationships. Or, perhaps this situation is deliberately left by Dumbledore to test these young wizards.

As the person most familiar with Old Bee, Cree could boldly guess that the latter possibility was even greater.

After staying for a few minutes, Cree turned and walked towards Professor McGonagall's office. After greeting her, Cree asked, "Professor, do you know if there are any tools in the magical world that can reverse time? Maybe not a long time, just a few minutes or even a few dozen seconds would be enough?"

Professor McGonagall's face didn't look too good at this time. She was overwhelmed by the poisoning of the students.

"Isn't the Time-Turner enough for you?" Professor McGonagall asked in confusion.

"No... I suspect that the person who attacked Hagrid has a device similar to a Time-Turner!" Cree slowly stated his guess: "Every time I'm about to catch him, he uses this device to turn back time, making me forget the past! He takes this opportunity to escape!"

Professor McGonagall frowned. She understood what Cree was saying.

Then, she took out a thick book from the bookshelf behind her, turning through it page by page.

This book was actually a notebook, Professor McGonagall's personal notebook.

"Time Hourglass!" Professor McGonagall said, pointing to a line of words in the notebook.

[Time Hourglass: It is said to be a magical tool from an unknown world. When the user inverts the hourglass, they can rewind the entire world by one minute.]

"One minute?" Cree frowned.

One minute is very short, but for a pursuer, one minute is too long. This one minute can change everyone's destiny.

Cree told Professor McGonagall all the information he had. After listening to Cree's speculation, the professor suddenly said, "Water pipes?"

Cree instantly understood that Professor McGonagall was talking about the way the attacker came to the castle.

Voldemort attacked those students and Hagrid through the water pipes, following the water flow.
