"Professor McGonagall, what about Headmaster Dumbledore? Hasn't he come yet? Ivan asked in a strange voice, there was no way Dumbledore hadn't come forward for such a big thing.

"Albus, he's been out for the last few days...", McGonagall explained, but at the same time a little helpless, Sirius had sneaked in at this time, and the coincidence made her a little suspicious that Sirius would have learned the news from somewhere.

Hearing this, Ivan confirmed his earlier suspicions, but in this case, things would be more troublesome.

Ivan originally wanted to go to Dumbledore with Spotted, saying that when he accidentally looked at this map last year, he found a human name on Ron Mouse's head, and he happened to meet Sirius during the summer vacation to find out the truth of the matter...

In the end, he could easily leave this troublesome matter to Dumbledore to deal with, and he could stay aside and watch the play with peace of mind, just waiting for extra points!

Only Dumbledore had enough prestige to convince everyone that Sirius was innocent, and to rehabilitate Sirius under pressure from the Ministry of Magic!

"Do you know what day Professor Dumbledore will be back?" Ivan sighed and asked.

"It should be soon, I've sent an owl to inform him... You don't have to worry too much, although Albus is not there, there are professors in various departments who can keep you safe, and if anything happens, you can tell me! Professor McGonagall reassured.

Ivan shrugged, he wasn't really worried about safety, but hesitated to explain Sirius to Professor McGonagall.

In the end, he stopped talking and decided to meet with Sirius first and discuss it.

The note Sirius handed him, Ivan hadn't read yet, but he thought it should have written the time and place of the meeting.

After all, Sirius couldn't explain a lot of things to him in his bedroom, it was too dangerous and easy to be heard, so finding a place outside to talk slowly was the right choice!

Ivan kept thinking in his mind, and unconsciously followed the crowd to the Great Hall.

McGonagall waved her wand to sweep aside the table that was in the way, clearing a large area in between.

However, McGonagall couldn't conjure up hundreds of sleeping bags with a wave of his hand like Dumbledore, and in order to preserve a certain amount of magic to deal with the possible attack of Sirius-Black, McGonagall thought about it and turned her head to Ivan.

"Hals, come and help me, we need hundreds of sleeping bags..."

Ivan nodded, stepped forward and drew his wand and nodded, and some small objects such as cups and saucers flew from the long table in the corner and landed in the clearing.

Then, as Ivan thought about the shape of the sleeping bag, the small objects twisted and changed, elongated, extended, and expanded, and soon a dozen or so blue sleeping bags appeared in the clearing.

At the same time, Ivan was also exhausted, and it was the first time he had tried to transform so many objects at the same time.

"Very good, you've improved a lot of your Transfiguration Charm lately..."Professor McGonagall looked at Ivan's transformed sleeping bag with a surprised expression.

She asked Ivan to assist her, and she did not use this opportunity to teach Ivan what it meant.

However, Ivan's growth has far exceeded McGonagall's expectations, and it can be said that each school year has changed a little drastically.

The rate of progress she had never heard of was unheard of, too fast...

Professor McGonagall couldn't help but sigh that in another year or two, she might have nothing to teach him.

Soon, however, Professor McGonagall gathered her emotions and spoke to Ivan:

"Hals, it seems that you don't have any experience in transforming items in batches before, and you are still a little lacking in this area, which is actually skillful.

You only need to focus on one of the items that need to be transformed, and then detach a trace of your mind to use magic to drive the others, and you will find that it is not difficult to practice a few more times..."

Professor McGonagall waved a few small objects and explained the details to be aware of when transforming in batches, and showed Ivan how soon seventy or eighty crimson sleeping bags appeared on the field.

After all this, McGonagall was still calm, not tired at all, and not as exhausted as Ivan...

It's just that Ivan can sense that the surface of these sleeping bags is fine, but in fact, he doesn't care, and it will take at most a day to be beaten back to their original shape.

Apparently this was done by Professor McGonagall on purpose, such a temporary transformation did not need to be too delicate, it was a waste of magic, and the sleeping bag made would last enough for everyone to sleep for a night.

Thinking of this, Ivan followed Professor McGonagall's prompts and tried again, transforming fifty objects at a time!

A large number of dishes, candlesticks and other objects quickly transformed into sleeping bags under the effect of magic...

Although the number of deformed objects has tripled this time, since Ivan does not need to exert all his strength like the first time, and the products he creates are inferior products that can only last for about ten hours, he just feels a little struggling, and the mana consumption is basically the same as just now.

At the same time, the prompt sound of the system also appeared in Ivan's mind.

[Ding, after a period of practice, your Transfiguration level has improved, and it is currently level 6]

Ivan was very pleased, since his Transfiguration had been promoted to level six, he hadn't increased his proficiency much in a long time, and he didn't expect to be able to increase so much with Professor McGonagall's guidance.

Looks like McGonagall's Transfiguration is a little more advanced than he thought...

Professor McGonagall nodded in satisfaction when she saw that Ivan had mastered what he had taught so quickly.

What professor would not like such a student who is actively working hard and can understand with a little mention?

Then, with the joint efforts of the two of them, hundreds of sleeping bags were neatly placed in the open space after half an hour's effort, and after these were done, a chaotic sound of footsteps came from the door of the auditorium.

Ivan turned around and saw that it was students from several other academies who had arrived.

"Professor McGonagall, what the hell is going on?" When the prefects of several colleges saw McGonagall, they hurriedly stepped forward to inquire about the situation.

When they received the notice, they hurriedly ran over and informed their dean that in order to save time, he only talked to them about the safety and asked them to pay attention to safety when they came, and did not say too many details.

"It's Sirius who has sneaked in..."Professor McGonagall explained the story in detail to the little wizards who didn't know much about it, and then comforted them, so that they didn't have to worry too much, the professors would take care of the matter!
