I really didn't want to practice immortality at Hogwarts

Professor Dumbledore waved his wand, and a colorful "thread" sprang out from the top of his wand and flew to the ground in a spiral shape.

Not long after, colorful flames suddenly shot up from the ground and burned quietly in the air.

Zhang Chun, the three of them and Professor McGonagall looked at the flames carefully, and they all felt uncomfortable!Because this flame is not a real flame, or in other words, it is not a flame in the conventional sense, because it has no heat at all, and it doesn't feel like it is burning anything.Even the roots of the flames were still on the carpet, which was unharmed.

But in addition to heat, colorful flames have other attributes that any flame should have.Whether it's in terms of shape, combustion method or other aspects.

Too strange!This is incredible!

Harry exclaimed.

Professor McGonagall even looked back at Dumbledore, "Okay, Professor! I regret making a bet with you now. You can actually use the lost secret magic!"

"It's not that it's lost, it's that they don't allow it to be used. In fact, secret magic is not difficult." Dumbledore said with a smile, and then he continued, "...then, Mr. Black, let us... eh? By the way, Black What? Why didn’t I see him? "

Zhang Chun and the others fell down directly...

I bet Professor Dumbledore also has such a side.

Professor McGonagall was also confused.

Dumbledore looked around before asking Zhang Chun. "Um...where's Mr. Black? Why didn't I see him when I came in?"

Zhang Chun thought as he climbed up, it was because you were holding back your bad plans to make a bet with Professor McGonagall and forgot about Sirius.

"Professor, he is sleepy...and I think he found a way to become bigger and smaller. He also turned into a villain and went back to sleep in the cube!" Zhang Chun added.

"Ah? Really, he can control his body freely?" Dumbledore raised his wand, looking surprised.

"Yes! But I think he has rested. I'll call him later!" Zhang Chun said.He walked towards the metal cube on the walnut table.

Now the metal cube was as big as a football. Zhang Chun knocked on the metal cube to wake them up...but he didn't expect that the metal cube seemed to be solid and couldn't be knocked at all.

"Sirius! Mr. Black! Professor Dumbledore is here and he wants to see you." Zhang Chun shouted.

As soon as he finished speaking, the metal cubes on the table suddenly began to click and deform!

Although this metal cube is not the source of fire in "Transformers", it is really transforming!

Following the crisp and pleasant sound of metal impact, the metal cube soon expanded into a large piece of space and plane.As everyone was stunned, they saw that the metal cube turned into a drop-shaped metal ball.

"How... is this possible?" Ron shouted first.

"It...how did this thing change just now?" Zhang Chun was also stunned.Seeing a square turn into a drop shape has subverted Zhang Chun's logic about Transformers' transformation.

Professor Dumbledore and Professor McGonagall also looked shocked, but they did not shout out because they relied on their status as professors.

Professor McGonagall had a look of disbelief on her face. She turned to look at Professor Dumbledore and remained silent for a long time.

Dumbledore answered frankly, "...Don't look at me, I don't know what's going on. Although I can't understand it, I'm shocked."

Before they could think any more, suddenly, the wall of the drop-shaped metal object began to melt...

Yes, it is melting!

A piece of metal dropped down from the middle of the water droplets as if it was melted, and then condensed in the air, turning into several steps.

Then, Sirius appeared at the empty wall, looking excited.

"Welcome, Professor Dumbledore, and Professor McGonagall!" Sirius' voice was loud, and he was not subject to the restriction of his voice after it became smaller.

"Thank you...ah, it's really you." Professor McGonagall stared at Sirius again and again before confirming that it was really him.

Professor McGonagall and Sirius were both members of the first generation of the Order of the Phoenix, so Professor Dumbledore had no problem with Sirius meeting her.

Professor McGonagall was surprised. She looked at Sirius in the metal drop and thought he was not much bigger than an ant.

"Did you become like this yourself?"

"Yes, and I can change back!" Sirius said, then walked out and stood on the walnut table.But he didn't stop and continued walking forward, and saw that he had reached the edge of the table...

Just when he was about to miss the mark, he transformed directly from the table into an adult and landed on the floor.

"Oh, my God!" Professor McGonagall exclaimed, covering her mouth.

Sirius smiled with a smile on his face, "Oh, Professor McGonagall, don't be surprised. This is not my ability, but this strange box. It contains a lot of magical magic. I just discovered it."

Harry quickly asked, "Does it also turn into French croissants?"

"Yes, haha, that's it."

Sirius was happy.

Zhang Chun understood that Sirius discovered the secret of spacecraft control after becoming smaller.

Sure enough, I heard from Sirius that after he became smaller, he came to the space deep in the spaceship. Since he was carrying a magical treasure (wearing Merlin's pants), he found that this space could be freely arranged as he wished.

Later, he was no longer sleepy at all and began to concentrate on studying the mysteries of the spacecraft.

Of course, the actual control was much more difficult than he thought. After all, it was not like Zhang Chun could get help from Vivian and Xiaoyi. He was just figuring it out by himself.

But even so, he was stunned to arrange more than a dozen rooms for the reclusive druids in the inner space of the spacecraft in a short period of time... and designed beds, furniture and other items for each room.

An outstanding real estate design master!Zhang Chun commented.

"The key is... I actually discovered that there is still water inside, and, you know, real spring water can be condensed in a place where there is nothing at all... It's amazing." Sirius's surprised and excited expression was enough to make everyone excited. Know how excited he is.

"What is this? Where did it come from!" Dumbledore frowned and asked.

For a moment, Sirius's expression was a little stiff, but he immediately returned to normal, and said according to the method he had just thought of, "...this is from King Arthur's...island, and the owner of this thing...should be related to King Arthur." A very deep connection..."

"Oh, that's it." Dumbledore said with a look of realization.

Zhang Chun covered his mouth and wanted to laugh. Sirius was also a talented person, but he was so surprised that he didn't say a word of lies, making everyone think he meant something else.

The unbreakable oath that Zhang Chun and Sirius made really works.
