Risk and Safety Boundaries of the Time-Turner

Ivan hung the Time-Turner around his neck, held the hourglass and began to turn it over.

One lap…two laps…

Yvonne counted off the number of revolutions in her head, and her surroundings began to blur. Even her senses seemed temporarily useless, as if she were isolated from the world.

As the number of revolutions increased, Ivan had the vague feeling that his mind was being affected.

119…120 laps!

Ivan's hand stopped moving, and the atmosphere returned to normal. The evening sun was shining through the windows, and the distant noise was audible.

Ivan had no intention of staying there, so he took the nearest secret passage to the Room of Requirement.

I need a place to hide!

They made it all the way to the eighth floor, Yvonne thought, opening the door.

It was spacious, like a small room, with enough material for him to live in for a week, and a magic calendar that automatically turned pages hung on the wall.

From the calendar date, Ivan determined that he was indeed five days old.

These supplies were prepared by Ivan shortly after school started, just for today!

He spent the next five days there to see what the risks of using the Time-Turner were.

…

A few days passed in the blink of an eye, and things went more smoothly than Ivan had expected.

Nothing happened during this time, as if the so-called risk never existed.

Ivan wasn't idle either, and he began to practice the charms he had mastered. He knew that he would most likely have to go through a fierce battle when he returned, and even the slightest improvement in his strength was important.

On the afternoon of the fourth day, as Ivan was about to take a break from his routine practice, a familiar feeling came over him.

Ivan found himself suddenly unable to move, and his feet no longer felt like they were on the ground. It was as if he had stepped on empty air, but he did not feel like falling.

Before he could figure out what was going on, Ivan felt something pressing down on him, pushing him forward. Blurred colours and shapes flashed past him.

Within moments, Ivan's feet were back on the ground, and all abnormalities vanished.

"What the hell is going on?" Ivan asked, cold sweat breaking out on his forehead. This was the first time he had ever experienced something like this while using the Time-Turner.

One thing was certain. The situation was extremely similar to every time he used the Time-Turner. Could the Time-Turner have activated on its own?

What time had he been transported to?

Ivan's head snapped around to look at the calendar, and he realised that he was only a day later, when he first used the Time-Turner.

Did I get kicked back to the same time?

A thought crossed Ivan's mind, but he wasn't entirely sure, and he tried to pull up the system's wizarding inventory.

The Risk Tips have become out of range, the Time-Turner will become vulnerable to damage, and the retention time will be unstable…

This meant that if one returned too long, they could be kicked back to their original point of time.

Ivan didn't know what to make of that.

Compared to the risk of losing one's lifespan or being thrown into time turbulence, being stranded for an unstable period of time is nothing.

It was different for Ivan.

He was going to save someone. If he could not determine how long he could stay in the past, he would not be able to set up the trap calmly. He could only choose to forcefully interfere at similar times!

This would undoubtedly add more uncertainty to his plans…

For example, he had once planned to return to the past and ambush the Dark Wizards in the Wizarding Shop with Alicia. If he suddenly disappeared during a battle and returned to his original time, the consequences would be extremely severe!

Ivan's expression changed several times, then he sighed helplessly. He had not expected the risks the System was referring to.

However, no matter how uncertain it was, he had to try!

Using the remaining time, Ivan repeatedly backtracked through the other rooms of the Room of Requirement, testing the safety limits of the Time-Turner and the exact duration of its retention.

I definitely can't stay in this room anymore, or I'll crash into my past self…

After a period of trial and error, Ivan found that the Time-Turner's safety limit was around five or six hours, beyond which there was a risk of being forcibly sent back to the original time point, and that the retention time was relatively random and difficult to determine.

Ivan did not dare to take too many tests in case the Time-Turner broke,

Fortunately, in many trials, the Time-Turner would burn slightly when the time limit was almost up, warning them in advance so that there would be warning signs.

And there was never a case of being kicked back as soon as you returned.

This somewhat reassured Ivan, and he mentally revised his rescue plan, wondering how he would fool his new self.

Oh yes, Harry's Invisibility Cloak!

Ivan suddenly thought of that. If he could get his hands on it, some of his actions would be much more convenient…

The Disillusionment Charm could not fool some highly skilled wizards, but the Cloak of Invisibility was a different matter. Unless one possessed a targeted magical object, no one would be able to detect one's presence unless one did not reveal themselves.

Yvonne considered this as she made her way to Hermione's classroom.

"Well, it seems I'm not too late…" Yvonne was relieved to find Hermione still fast asleep in her bed.

This time, he was delayed and did not return as expected…

Luckily Hermione had not woken up, or he would have had a headache trying to explain.

After all, the witch was smart enough to know that he was hiding something from her.

Ivan didn't want Hermione to get involved in something so dangerous, and he didn't want to be distracted in a fight…

With that in mind, Ivan hung the Time-Turner back around the witch's neck and sat in the corner to continue his research.

The improved Polyjuice Potion would not be ready until at least the day after tomorrow, and the Time-Turner was of no use to him now, as Ivan had already confirmed everything that needed to be confirmed.

It would be best not to raise Hermione's suspicions, as she might turn to Dumbledore for advice and cause trouble.

Ivan shook his head to clear his mind of these thoughts and immersed himself in the development of the potion.

After what seemed like an eternity, Hermione finally opened her eyes…
