Collect dragons from Hogwarts

"Come in, I'm not asleep yet."

After hearing Zhang Zhe's answer, Grindelwald opened the bedroom door and walked in.

When he saw Zhang Zhe's true form, he was stunned for a moment.

"Xiao Zhe, I have to say that your body is so beautiful. No matter how many times I see it, you still have a soul-shaking beauty."

Grindelwald had seen Zhang Zhe's fantasy dragon in its original form.

To be more precise, Zhang Zhe met Grindelwald in his true form.

"Thank you for the compliment." Zhang Zhe replied with a smile.

Then, he looked at the newly tidied Grindelwald.

It has to be said that Grindelwald is indeed the most powerful wizard Zhang Zhe has ever seen, besides Dumbledore.

His short white hair and old face could not conceal his majestic temperament.

And even if he is an old man, you can vaguely see the shadow of his handsomeness when he was young.

"I didn't expect you to be so handsome, Grindelwald."

Faced with Zhang Zhe's compliment, Grindelwald touched his chin and winked at Zhang Zhe.

"That's because you don't know that when I was young, I was the most handsome person in the wizarding world. I have fascinated many witches."

Zhang Zhe was disgusted by Grindelwald's greasy expression and had goosebumps all over his body.

"Eh~~, you are so disgusting, Grindelwald."

The two had fun for a while.

Grindelwald sat beside Zhang Zhe's bed, and Zhang Zhe laid the dragon's head on his lap.

Grindelwald stroked Zhang Zhe's faucet and said, "Are you ready for everything for school? It's time to go to school in a few days."

"Holm has bought the books needed for first grade, and I've bought other things today."

"Well, then you should go to bed early. I will continue to teach you English and runes tomorrow."

Zhang Zhe had not read many books before, so he did not know English at all.

He can now converse fluently in English because he has a powerful brain after becoming a fantasy dragon.

When he was in Nurmengard, he spent more than a week learning it from Grindelwald.

Even so, Zhang Zhe still couldn't understand some English.

And he didn't know many of the runes needed to cast a spell.

He originally planned to go to Hogwarts and wait for Dumbledore to teach him, but now that Grindelwald is back, there is no need for it.

Patting Zhang Zhe's faucet, Grindelwald stood up and left, ending the warm atmosphere.

……

The next day, when Grindelwald was teaching Zhang Zhe in the hall on the first floor, Home led an angry Dumbledore in.

"Gellert Grindelwald, how could you leave Nurmengard!"

Faced with Dumbledore's angry questioning, Grindelwald said expressionlessly: "Why can't I leave?"

Grindelwald's answer stunned Dumbledore for a moment.

"You, you clearly... promised me..."

When Dumbledore didn't know what to say, Grindelwald waved to Zhang Zhe and asked him to leave.

Zhang Zhe glanced at him and said, "I'm going upstairs first. Remember to call me when you're done. I still don't know a lot of runes."

"Yeah." Grindelwald smiled and nodded.

Then, Zhang Zhe left under Dumbledore's complicated eyes.

When Zhang Zhe left, he faintly heard Grindelwald's voice.

"Dumbledore, I have stayed in Nurmengard for decades for you, isn't that enough?"

"Now that I am old, in my last few days, shouldn't you even give me a chance to spend time with my family?"

.........

Zhang Zhe sat on the windowsill of the bedroom, looking at the green lake in the distance, not knowing what he was thinking.

It wasn't until the knock on the door that he came back to his senses.

Seeing Grindelwald walking in, Zhang Zhe ran over and hugged him.

"OK OK."

Hearing Grindelwald's comforting words, Zhang Zhe looked up at him and showed a smile.

Grindelwald also smiled.

"I won't study today. I heard from Holm that you want to transform a den for pets on the third floor. Let's do it today."

Zhang Zhe nodded and let go of Grindelwald.

The two came to the third floor of the castle together.

"I plan to demolish most of the rooms on the third floor above my bedroom, and even a small part of the roof will be demolished to serve as the entrance and exit of the lair."

Grindelwald was shocked by Zhang Zhe's plan.

"Most of the third floor is at least five to six thousand square meters. Are you sure you need such a big space?"

Zhang Zhe waved his hand and said with a smile: "This little place is just for the initial use of my pets."

"When I have more pets and grow up, I want to fix the traceless expansion spell on this nest. The space must be expanded at least thousands of times to be enough for them to live in."

Grindelwald knocked Zhang Zhe.

"You really dare to think that fixing the Traceless Stretching Spell will be more difficult the larger the original space is."

"It's impossible to even expand a nest of five to six thousand square meters like yours a hundred times. It can only reach ten times at most."

Zhang Zhe's eyes widened: "No way, the cloth bag that Holm gave me has expanded 10,000+ times! Even if the size of the original space is different, the difference won't be that big, right?"

Knowing that Zhang Zhe lacked knowledge of things in the wizarding world, Grindelwald patiently explained to him.

"The cloth bag Holm gave you is an alchemy item passed down from long ago."

"With the passage of time, a lot of alchemy technology in the wizarding world has been lost, and it is far inferior to what it used to be."

"Nowadays, there is only one person in the world who can fix a hundred thousand times traceless stretching spell in a palm-sized cloth bag."

"The remaining alchemists can only fix a ten thousand times traceless stretching spell in this bag at most, and there are not many such alchemists. There should only be three or four in the world."

Zhang Zhe lowered his head, thought for a moment and said, "Then the most powerful alchemist you mentioned, how many times can he expand this nest with his fixed traceless stretching spell?"

Grindelwald tapped his chin and said, "It should be able to expand one to two hundred times!"

"Then can you ask him to help me? I can give him a generous reward. I have a lot of gold coins." Zhang Zhe said with starry eyes.

Grindelwald said dumbfounded: "Those gold coins of yours were not given to you by me, but they are all my property!"

"Hehe." Zhang Zhe smiled sheepishly.

"For an alchemist, especially a powerful alchemist, they don't lack gold galleons."

"And the most important issue is that I have some grudges with that alchemist, so he can't help me."

Hearing Grindelwald's words, Zhang Zhe could only nod helplessly.

Looking at the disappointed Zhang Zhe, Grindelwald touched his head.

"There is a problem with your nest plan. If you wait to fix the Invisible Stretch Charm on the nest later, your strange pets will not be able to hide it from outsiders, so it is best to fix the Invisible Stretch Charm from the beginning."

"After all, I don't know how to do alchemy. If you want to fix the traceless stretching spell, you still need to hire an alchemist from outside."

Grindelwald had seen Xiaohong yesterday, and he had never seen that incredible transformation in his life.

Therefore, the fewer people who know Zhang Zhe’s pets, the better.
