Ivan hung the time-turner around his neck, held the hourglass and began to flip,

One lap .. Two laps....

Ivan silently counted the number of spins in his mind, and the scene around him began to blur, and even his senses seemed to have temporarily lost their effect, as if he was isolated from the whole world.

As the number of spins increased, Ivan even had a vague illusion that his mind had been affected.

One hundred and nineteen... One hundred and twenty laps!

Ivan's hand stopped, and the surroundings had returned to normal. The evening sun shone through the windows, and the noise in the distance was heard.

Ivan had no intention of staying here, and went through the nearest secret passage to the Room of Requirement.

I need a place to hide!

Walking all the way to the eighth floor, Ivan said a silent sentence in his heart, and then opened the door.

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

Judging by the date of the calendar, Ivan was sure that he had indeed returned to five days ago.

These supplies were prepared by Ivan for Dobby shortly after the start of school, for today!

He'll spend five days here to see what the risks of using a time converter for long periods of time are involved.

......

In the blink of an eye, a few days passed in a flash, and things went smoothly beyond Ivan's imagination.

In the meantime, nothing happened, as if the so-called risk had not existed at all.

Ivan was not idle, practicing the spells he had mastered, he knew very well that he would probably have to experience a fierce battle when he returned, and even a little improvement in strength was especially important now.

On the afternoon of the fourth day, when Ivan was ready to take a break after his usual practice, a familiar feeling hung over him.

Ivan found that he could not move suddenly, and his feet did not feel like they were stepping on the ground, as if they had stepped on an empty place, but he did not feel like he was falling.

Before he could figure out what was going on, Ivan felt his body squeezed by something and rushed forward, blurred colors and shapes flashing by.

In a moment Ivan's feet were back on the ground, and everything was gone.

"What the hell is going on?" Cold sweat broke out on Ivan's forehead, it was the first time he had encountered this kind of thing while using the time turner.

One thing is for sure, the situation just now is extremely similar to the time converter he used every time, could it be that the time converter started on its own?

So at what point in time have you been teleported to now?

Ivan jerked his head to look at the calendar, and realized that he was only a day later, when he had used the time turner.

Am I being kicked back in time?

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

The above risk warning has become out of reach, the time converter will become easily damaged, and the residence time is extremely unstable...

In other words, if you return for too long, you may be kicked back to the original point in time at any time.

Ivan didn't know what to say for a while,

Compared to the risks of losing life and being thrown into time turbulence, the instability of the residence time is nothing, and in the eyes of some people such a risk is even negligible.

For Ivan, it's different.

He is going to save people, if he can't be sure how long he can stay in the past, he can't calmly make the layout, he can only choose some similar time periods to forcibly intervene!

In this case, it will undoubtedly add more uncertainty to his plans...

For example, he once planned to go back to the past and ambush those dark wizards in the magic shop with Althea, if he suddenly disappeared during the war and returned to the original point in time, it would definitely cause extremely serious consequences!

Ivan's face changed and changed, and finally he sighed helplessly, he didn't expect that the risk that the system said actually meant this.

But no matter how uncertain there is, he has to give it a try!

Using the remaining time, Ivan traveled back several times in the other rooms of the Room of Requirement, testing the safety limits of the time turner and the exact length of his stay.

I can't stay in this room now, otherwise, I'm going to collide with my past self...

After a period of attempts, Ivan discovered that the safety limit of the time turner was about five or six hours, beyond which he could be forcibly repatriated to the original point in time, and the detention time was relatively random and difficult to determine.

Inevitably, the time converter was damaged, and Ivan did not dare to do too much testing,

Fortunately, in many tests, the time turner will be slightly hot when the retention time is almost up, and it will be warned in advance, so that it will not be without warning.

And there hasn't been a single situation where you have been kicked back just after you go back.

This made Ivan somewhat relieved, and he mentally revised his rescue plan, thinking about how to fool his past self when the time came.

That's right, Harry's Cloak of Invisibility!

Ivan suddenly thought of that, if he could get his hands on it, some of his actions would definitely be much easier...

The Illusion Charm can't hide from some clever wizards, but the Invisibility Cloak is different, unless you have some targeted magic items, as long as you don't show your flaws, no one can find out.

Ivan thought in his head as he walked towards the classroom where Hermione was.

"It's good that I didn't arrive too late," Ivan was relieved to see that Hermione was still asleep on the bed.

He was delayed for some time this time, and he didn't come back with his front foot just after leaving as expected...

It's a good thing that Hermione hasn't woken up yet, otherwise he would have had a headache how to explain,

After all, with the intelligence of the little witch, she found that the time turner disappeared, and she must have guessed that she had something to hide from her.

Ivan didn't want Hermione to be involved in such a dangerous thing, and he didn't want to have to be distracted to protect others while fighting...

Thinking of this, Ivan hung the time turner back on the little witch's neck, and then sat down in the corner to continue his research.

The improved version of the compound decoction will not be finished until this time the day after tomorrow at the earliest, and the time turner is useless in his hand now, and Ivan has already confirmed everything that should be confirmed.

It's better not to arouse Hermione's suspicions, or she might turn to Dumbledore for advice and not know how much trouble it will cause.

Ivan shook his head, leaving these complicated thoughts behind him, and devoted himself to the research and development of potions.

After I don't know how long, Hermione, who was sleeping in a daze, finally opened her eyes....
