Of course, this thought only flashed through Ivan's mind, and if he died again, Snape would still have a real chance of deducting a large number of Gryffindor house points.

Ivan didn't care about that, but he wasn't going to make the entire Gryffindor House lose money by earning GPA.

So in the next few days, when Ivan was in Potions class, he didn't make any big moves except for making small moves in private and collecting some materials needed to make hypnotic potions.

This preparation continued until Halloween, and Ivan looked at the system bar, still satisfied with his results.

After nearly half a semester of hard work, in addition to the newly learned shrinking spells, Ivan has raised all the spells he knows to the second level, both in terms of power and stability, compared to the first level.

Among them, the knowledge of potions is the first to reach the level of level three, and the only thing that remains unchanged is the production of magic items, and Ivan has no clue for the time being. GPA also leaves enough amount for a one-time experience card, just in case.

In anticipation of the upcoming Halloween, the halls of Hogwarts have been hung with jack-o-lanterns, which contain the magic released by Dumbledore himself, which can continuously emit a faint blue light.

Peeves also sinisterly hid in one of the lanterns, and whenever an unwitting little wizard passed by, Peeves would suddenly emerge from the lantern to startle him, and then laugh and get into the other lantern amid the little wizard's scolding.

But I have to say that it is precisely because of the presence of Peeves that this Halloween has more of the scary atmosphere it should have.

At the very least, Harry and Ron felt the festive spirit brought by Peeves, and as long as they saw the glowing pumpkin lanterns in the castle, they would subconsciously stay away.

"Ivan, what are you doing with so many thorny spikes?"

In the large exhibition hall, on the long table of Gryffindor, Harry watched Ivan turn the wooden branches he had picked up from nowhere into semi-circular spikes, and wondered.

The semi-circular iron brambles were ugly, but the spikes on them were thin and long, and Harry shivered with a faint cold light.

"Of course, it's for everyone to have some fun on Halloween." Ivan said with a smile.

"Fun?" Harry and Ron looked at each other, always feeling a bad feeling.

"Just kidding, just practicing spells." Ivan waved his hand and opened his mouth to explain.

But Ivan's hand did not stop, he waved his wand and pointed at the spikes that had just been transformed, and after shrinking the spikes dozens of times with a shrinking charm, he threw them into the bag.

There was a metal clash in the bag, and Ivan put it away with his backhand.

"By the way, what about Hermione?" Ivan looked left and right and didn't see Miss Know-it-all, and couldn't help but feel a little strange.

"Well. This—" Ron's face flushed slightly, and he didn't get a few words out for a long time.

In the end, Harry, who still couldn't stand it, told him what happened to be heard by Hermione when Ron secretly said bad things today.

"I'm not wrong, she's like that!" Ron blushed.

Ivan frowned, he didn't expect that he was there, and this happened anyway. After thinking about it, Ivan stood up and picked up his wand and walked towards the exit of the hall.

"Ivan, the banquet hasn't started yet, where are you going?" Harry asked.

"Hermione, of course..."Ivan replied, leaving only Harry and Ron with a back.

Leaving the bustling large exhibition hall, Ivan found a secret passage and went to the abandoned girl's bathroom as fast as possible, intending to persuade Hermione to leave first, so as not to disturb his future actions against the trolls.

However, after careful consideration, Ivan changed his plan again, because Ivan was a little unsure of how long it would take him to persuade Hermione to leave, and he didn't know when the troll was released, if he happened to be blocked by the troll while he and Hermione were in the bathroom, let alone fighting, it would be difficult to escape!

In contrast, it is better to deal with the trolls directly in a place a little further away from the bathroom.

Ivan quickly found a suitable corridor and threw a few pieces of the crust cake that Hagrid had given him to the center of the hallway.

These crust loaves were soaked in powerful sleeping potions, enough to fit several adult wizards.

As for why rock skin cake?

Ivan said that the trolls are not picky eaters anyway, they eat everything, and the rock skin cake is carried, so it is considered to be waste, otherwise it will be put in the bedroom waiting for bugs?

If Hagrid, a half-giant, likes to eat so much, maybe the troll might as well take a bite?

After being well prepared, Ivan hid in the secret passage on the side of the corridor, and was able to defeat the troll in the easiest way.

There is only one life, and when it is time to coax, you still have to coax.

Less than a minute after Ivan was ready, there was a slight vibration on the floor, Ivan faintly smelled a foul smell, his expression suddenly froze, and he was extremely nervous, the troll had arrived!

The next moment, a twelve-foot-tall behemoth appeared on the other side of the hallway.

The first thing Ivan saw was a thick paw that seemed to have a thin skin, and the troll's fat waist was like a huge bucket made of a dilapidated ancient tree, and it was also painted with a layer of ugly green paint, and the top small head looked a little bigger than Ivan at most, with a burly body, it looked a little ridiculous.

The most important thing is that it also holds a thick wooden stick in its hand, and it drags it on the floor with a sharp and piercing sound.

Ivan swallowed hard, and then understood why Dumbledore chose trolls as one of the levels to defend against the Philosopher's Stone, and the sheer size of the body alone was enough to make an adult wizard cautious.

And for a young wizard who has not yet graduated from the wizarding academy, it is even more nightmarish existence!

Ivan couldn't help but rejoice that he didn't choose to be tough directly, if he accidentally got hit by the troll's big stick, he might have to cross once...
