As if he had drunk too much, the little dragon staggered and crawled on the table with his feet propped up.

Carl reached out and touched the little dragon's head, and surprisingly, the little dragon did not repuls, but showed a comfortable expression like a kitten.

"Looks like she likes you, Carl, but be careful, it's not a joke to get bitten by its teeth, it's poisonous. Dumbledore said with a smile and touched it, but immediately withdrew his hand so that it was not bitten by the dragon.

"What's going on?" Karl asked curiously.

The little dragon didn't treat Dumbledore the way he did him.

I guess it's not like I'm treating him as a mother.

Carl looked odd.

If that's the case, what would he say to Hagrid?

"Gellert and I used a lot of precious materials to create you, including the blood of the Ancestral Dragon, found in an ancient ruin. ”

"I think she thinks you're her ancestor or something. ”

Well, it's more than being treated like a mother.

But......

Karl looked at Dumbledore with a blank eye, and the precious material that the old man had said before turned out to be this kind of thing.

"Except for dragon blood?" he asked.

The old man thought for a moment, "I remember that Fawkes also contributed a drop of blood, and also used some of the blood of the primordial unicorn - not the kind in the Forbidden Forest, but a winged unicorn, very rare, or Gellert caught it, after so many years, I don't know if it is still alive." ”

At this moment, Carl finally understood why Xiaobai surrounded him as soon as he saw him.

"Of course, there are also the blood of several other creatures and some more precious alchemy materials in addition to those of Gellert......"

As he spoke, Dumbledore waved his wand, and a pamphlet with a leather cover appeared out of thin air.

"Most of the materials used are listed on it, so if you're interested, you can check it out. ”

......

Karl sat in Hagrid's hut, intently flipping through the booklet Dumbledore had given him.

Dumbledore sat on the side without interruption.

The booklet not only records the materials used, but also various advanced alchemy formulas and precautions.

Carl admits that he wasn't interested in anything like alchemy potions, but after seeing what was written in the booklet, he became a little addicted to it.

The little red dragon seemed to really regard him as a relative, and climbed up and down on him with all his might, and finally, lying on his shoulder, staring curiously at the booklet in Carl's hand.

Suddenly, it sneezed, and a few sparks came out of its nose and landed on the booklet in Carl's hand, leaving several small charred holes in it.

"Ouch!"

Carl, who was concentrating, was immediately startled and subconsciously stood up from his chair.

The little dragon on his shoulder didn't grasp it firmly, and his body swayed and fell, falling heavily on the ground, making a "plop" sound.

Carl didn't care about the booklet, and quickly squatted down to check on Xiaolong's situation.

After all, the little dragon just fell not lightly.

Gently picked up the little dragon from the ground with his hands and slowly placed it on the table.

The little dragon turned over with difficulty, raised his head, and stared at Carl with a look of grievance.

Carl breathed a sigh of relief, he could show this expression, it should be fine.

It's just that, looking at Xiaolong's pitiful expression, he couldn't help sighing, stretched out his hand and touched Xiaolong's head.

After calming for a long time, the grievances on Xiaolong's face gradually disappeared, and he returned to his previous appearance of being very curious about everything around him.

At this point, Carl remembered the booklet that had been burned by Mars, waved his wand, and restored the booklet in his hand.

The whole process, Dumbledore, who had been standing on the sidelines, watched it all.

When Karl was seen inspecting the dragon before paying attention to the booklet, he seemed to have made some kind of determination.

After Carl had taken care of everything, he slowly spoke:

"Carl, I think it's almost time. ”

"What's the time?" said Carl subconsciously, looking away from the dragon and looking at Dumbledore.

"I told you two days ago......" Dumbledore said with a smile.

"You mean?!" Carl couldn't help but get excited.

Dumbledore smiled and nodded, "Yes, next, I'll teach you something myself." ”

......

Hogwarts Castle, on the eighth floor, opposite the tapestry where the troll stick beats Silly Barnabas, there is the entrance of the Requirement House.

"Carl, it looks like you've known this for a long time. ”

Seeing Karl calmly looking at the door that was gradually appearing in front of him, Dumbledore said cheerfully.

"This way, we can save a lot of time explaining and focus on what we want to do. ”

"Professor, why should I take them?" Karl pointed to the little red dragon hanging from his chest like a sloth, Hades on his left shoulder, and Hela on his right shoulder.

"Next, we're probably going to disappear for a while, you don't want them to be starved, do you?"

"They can find food on their own. Karl looked at Dumbledore speechlessly.

From the time he bought Hela to the present, he has fed her only a handful of times.

Hearing this, Dumbledore joked, "Karl, I have to say, as a master, you are not very qualified. ”

After saying that, he blinked mysteriously, "Don't worry, they will come in handy." ”

It made Carl puzzled for a while.

"Wait, you just said it would disappear?" Karl looked at Dumbledore quizzically.

As far as he knew, the Room of Requirement did not have the function of making people disappear.

Dumbledore looked at him with a smile and said, "Carl, very few people can find the existence of the Room of Requirement, and even fewer can find out what he really uses on that basis. ”

"Uh......"

Now, Carl was even more confused.

He had never heard of any other use for the Room of Requirement.

"You'll find out soon. Dumbledore said mysteriously.

“......”

Karl looked at Dumbledore helplessly, obviously, the old man's old mistake had been repeated.

Dumbledore seemed to be unconscious, he looked at Karl solemnly, and said with a serious expression.

"Carl, Tom and Gellert have already taught you a lot when it comes to pure magic, so I'm going to skip the part they teach you......"

"So, be prepared, because you and I will be exploring the depths of magic, and even I don't know what will happen next. ”

With the old man's wand, the door of the Room of Requirement slowly opened.

First, Dumbledore stepped inside.

Helpless, Carl had to follow with a pendant.

As the two enter, the door slowly closes, eventually reintegrating with the wall.

......

......

......

Half a minute later, the door of the Room of Requirement resurfaced from the flat wall.

With a bang, a figure slammed open the door and rushed out of it.

It was Dumbledore.

The old man looked anxious, and his eyes scanned the entire corridor on the eighth floor several times, but he couldn't find what he was looking for.

At this point, Dumbledore was dumbfounded.

Carl lost.
