When they returned to the original unmanned classroom, the two stared at each other, and the atmosphere was very embarrassing for a while.

Ivan also put out the thought of reprimanding Hermione, after all, Madam Pomfrey said that her situation was much more serious than Hermione's.

"Looks like we're going to have to make a detailed schedule!" Ivan sighed helplessly, there would be problems with a chaotic routine like before for a long time.

Ivan then began to re-establish a new schedule, the most important of which was to limit the use of the time converter.

Go back up to 30 hours a day, try to avoid going back in time multiple times at the same point in time, drink a bottle of tonic every three days, etc...

After strictly setting the schedule for rest, the next few days were much more relaxed for both of them, but the progress of potion research and development slowed down a lot.

Even though Ivan invested all the GPA earned from attending classes every day, there was still a core problem that could not be solved.

That was why the effect of the compound decoction suddenly disappeared when those black-robed wizards were used for experiments at the beginning.

Thinking of this, Ivan frowned deeply.

After hesitating for a moment, he picked up the compound decoction that had been prepared on the table, casually added a hair that he had collected in school these days, and drank it in one gulp, and soon his body was deformed.

Ivan looked in the mirror next to him, and he had become a thin little wizard.

"Shadowless!"

When the effect of the medicine stabilized, Ivan put his wand against his arm and gently recited the spell, releasing the spell.

The invisible blade of magic sliced through his skin, blood running down the wound, and the table was bright red.

Hermione, who heard the noise, turned around and was startled when she saw a strange little wizard with long wounds on his arms.

Hermione instantly guessed that it was Ivan who had drunk the Polyjuice Potion in front of her, because it was just her and Ivan who were just two people here.

Seeing a large amount of blood flowing from Ivan's wrist, the little witch panicked all of a sudden.

Fortunately, she remembered that she had seen in the book "Advanced Potion Making" that Bai Xian could heal injuries, so she immediately rummaged through it, grabbed a Bai Xian, ran over like crazy, pulled Ivan's injured arm, and dripped Bai Xian's juice on the wound.

However, the wound was still bleeding, and the white juice did not have the slightest effect.

"It can't be! Why is it useless? Hermione said eagerly, with a hint of crying.

Ivan didn't expect Hermione to have such a big reaction, and hurriedly explained.

"Don't worry, Hermione, I'm just doing an experiment... This is just part of the experiment. ”

As he spoke, Ivan placed his wand into the wound, and whispered a chanting spell in his mouth, and the wound on his arm healed immediately.

He was just testing the stability of the potion, especially if the drinker would suddenly revert back to its original state or affect the potion's effects when the drinker was severely injured and healed.

Experiment?

Hermione watched in a daze as Ivan's arm slowly recovered, and even the blood stained on the table returned to the wound, and she didn't reply for a long time.

Ivan was a little worried, and was about to ask, when he saw Hermione gritting her teeth, clenching her fist and waving it, slamming it into his stomach.

Under the compound decoction, Ivan suddenly stumbled, almost hit the crucible behind him, and when he stood up holding his stomach, he saw that Hermione's eyes were a little red.

"How would anyone cut their own arm for an experiment? Can't you experiment with something else? Hermione was furious, "And you didn't let me know in advance!" ”

Looking at Hermione, who was trembling with anger, Ivan opened his mouth, wanting to explain, but he didn't know where to speak, so he scratched his head helplessly.

He didn't think so much about it when he was researching potions, he tried it completely on a temporary basis, and when he cast the spell, he deliberately controlled the power of the Divine Blade Shadowless Spell, and there was no danger.

Who made Polyjuice Potion only useful to people, he couldn't have grabbed a few young wizards in Hogwarts to use as experiments, right?

Ivan wasn't cruel to that extent, and if it didn't hurt anyone, Dumbledore would have torn him alive...

If only I could find a "guinea pig" who is full of sin and has a tenacious vitality, and no one cares about it even if he accidentally hangs up during the experiment...

Ivan sighed in his heart, not only would his potion improvement efficiency be much higher, but he would not have to experiment on his own body all the time.

Wait a minute... It seems that there is such a person!

Ivan suddenly thought of something, and a little surprise appeared on his face,

Spotted, you're my savior!

"Ivan, have you come up with a plan for potion improvement?" Hermione looked at Ivan's face and suddenly became happy, and the anger that had surged in her heart was temporarily suppressed, and she asked with concern.

"No, I just thought that some experiments could have been experimented with by a mouse...", Ivan explained, he would have forgotten everything, and with the stun charm, Peter would have no feeling afterwards.

"So you're only now thinking of using rats as test subjects?" Hermione glared angrily, like a lioness.

Ivan smiled bitterly, he said that the experiment was not an ordinary mouse.

It is the Animagus like Peter Pettigrew that can meet his experimental needs!

He's going to have to find a way to get that man from Ron, the rat here!

It's just that this point is destined not to be told to Hermione, and Ivan only apologized for a while, promising never to carry out such a dangerous experiment on himself again, and Hermione no longer pursued this matter.

I knew that if there was an experiment, Ivan would be stupid and would use his body to do the experiment.

However, Hermione finally kept a straight face, apparently not yet angry, and ignored him all morning, looking through the potions books to herself.

Ivan shook his head and didn't care, and continued to devote himself to the study of potions.

After waiting for about an hour, Ivan could clearly feel that the effects of the compound decoction were beginning to fade away.

It seems that the effect of previous damage on the Polyjuice Potion should be small, not to the extent that it interrupts the potion effect.

"Why aren't there any books dedicated to potions on the bodies of the dead?"

At noon, Ivan, who returned to the auditorium for lunch, sighed with a headache, he felt that the fragrant steak in front of him didn't seem to be so fragrant...

He had been rummaging through all the potions books he could find in the past few days, and found that there seemed to be no corresponding research records.
