Hermione's fair cheeks flushed, she didn't think she could even help a little bit...

While discussing the improvement plan with Ivan, Hermione was even more hesitant, and the flush spread from her cheeks to the base of her ears.

Ivan also slowly noticed this, and after thinking about it, he was not surprised.

He had read the Blake's collection of books and Snape's research notes during the summer, and Hermione, even if she was a genius, couldn't keep up with him.

Ivan thought for a moment, and suddenly snapped his fingers.

"Sir, do you have any instructions?" An ugly house-elf suddenly appeared in front of the two.

"Dobby, go get the book I asked you to buy!" Ivan spoke.

"Yes, sir!" Dobby nodded.

Then, under Hermione's puzzled gaze, Dobby cast a phantom shift and disappeared in front of the two of them, and when he returned, he already had more than a dozen potions books in his hand.

Ivan is very happy with Dobby on call, and it's no wonder that many wizarding families like to keep a house elf.

However, Ivan didn't dare to let Dobby stay too long, and after seeing that he had put the book away, he motioned for Dobby to leave.

Because maybe there are other times when you want to summon it...

"If you want to help, read these books first..."Ivan took out Snape's "High Potion" and handed it to Hermione.

The research notes that Snape had left behind had long since been torn up by him, and they were no longer useful to Ivan now.

But Ivan felt that the book should be of great help to Hermione.

Hermione looked at the books, gently holding the time turner on her chest, and nodded earnestly.

After assigning a study task to the little witch, Ivan plunged headlong into the study of potions.

Now he didn't expect Hermione to help him, he just wanted to find her something to do and not disturb his research.

Hermione didn't give up on herself, she sat quietly with these books and flipped through them, holding a stack of parchment, taking notes seriously, and soon filled with pages and pages of reading notes.

This life lasted for three days, and Ivan was stunned to find that Hermione had read all the books and was able to make some useful suggestions while he was researching the potions improvement scheme.

It's like a different person...

Are you also hanging?

Ivan was confused, but soon noticed the look of exhaustion on Hermione's face.

Almost instantly, Ivan thought of the time turner, only to feel a cold sweat on his back, and asked very seriously.

"How long have you been going back in the past few days?"

"What is this for?" Hermione hugged the book and said with a little weakness. "That's about ninety hours, right?"

"Are you sure that's all there is to it?" Ivan frowned, ninety hours was not enough to initially master the contents of so many potions books.

Hermione nodded, but she didn't tell Ivan about the ninety hours, not including the time the two of them had spent backtracking together.

"The power of the time turner is powerful, but it is also dangerous, it is a power that we don't know at all, and if you use it frequently in a short period of time, you may cause some damage to your body. Also, Dumbledore should have told you that a single backtrack that takes too long can lead to a loss of control. Ivan said warningly.

"I'm mindful that it's up to five hours at a time." Hermione retorted softly.

Ivan was still a little uneasy, and finally dragged Hermione to the school hospital, intending to let Madam Pomfrey see if there were any after-effects or something.

In the school hospital,

Madam Pomfrey was treating a Hufflepuff player for a fall, and after hearing Ivan's request, she took Hermione seriously.

"Miss Granger, how the hell did you get yourself to be like this?" Madam Pomfrey frowned and rebuked.

"Is it serious?" Hermione was scared.

Ivan was also nervous, he didn't want something to happen to Hermione because of his own affairs.

"That's not it, it's just that because I've been in a state of mental tension for a long time, I'm tired, and it's good to cultivate for a while." Madam Pomfrey shook her head and explained.

Then, without waiting for the two to breathe a sigh of relief, Madam Pomfrey looked at Ivan again.

"So do you, Hals! You're so much worse than Miss Granger, and you'd better tell me honestly how long it's been since you've slept well? ”

Madam Pomfrey really couldn't understand why the two thirteen or fourteen children were so tired that they lacked energy.

They're at their most energetic...

It's only been a few days since school started, what are they doing?

Ivan was a little embarrassed, he didn't expect him to bring Hermione with him, but in the end he implicated himself.

However, to Ivan's good news, the problem is not serious, and it should be solved by just resting more and drinking some energy tonic.

It seems that the use of a time turner will not cause any irreversible serious consequences to the body.

Yes, otherwise the Ministry of Magic wouldn't have given it to them.

A few thoughts flashed through Ivan's mind, and he had to face Pomfrey with a black face.

Obviously, without giving a suitable reason, Pomfrey wouldn't let them go so easily.

"I'm sorry, Madam Pomfrey, we've had too many schoolwork lately, so we don't have much time to rest, maybe that's the reason, we'll pay attention to it later...", Ivan said half-truthfully.

"It's the first time I've seen learning to learn like this." Madam Pomfrey couldn't laugh or cry.

If it were a young wizard, she would not believe it.

But Madam Pomfrey had also heard of Ivan's deeds in the past two academic years, and she had worked so hard to be worthy of his current achievements.

Hermione was also an honor student in all subjects, so this reason still stands.

Madam Pomfrey quickly boiled two bowls of black potions and brought them over, and there were many unknown items floating on the turbid potion, the kind that people didn't want to drink at first glance.

Can I not drink it? Ivan was quite helpless, he felt that after he went back, it would be good to make two bottles of energy tonic by himself, and there would be no need to be so troublesome.

Madam Pomfrey shook her head firmly.

Ivan had no choice but to pick up a bowl of potion and pour it down, his mouth was very bitter, it felt like the Chinese medicine he had drunk in his previous life.

After drinking, Ivan felt that his brain was cold and much more sober.

Ivan turned his head to look at Hermione opposite, the little witch was holding another bowl of potions, drinking them one by one, her brows furrowed...
