When Calvin arrives at Hagrid's hut, he is using a bucket to block the fireplace, trying to hide the dragon's egg.

"Hagrid," Calvin waved his hand, pushed him to a chair next to him, and crouched down beside the stove to take a closer look at the dragon's egg.

At this point, Harry and the others arrived, and Harry pale to Hagrid explaining that he was doing it to help him.

"Harry, you shouldn't." Hagrid said angrily, but on second thought, there was no better way, after all, Calvin was not only his good friend, but also a master of magical beasts.

Calvin pulled a tube of blue potion out of his sleeve and poured it onto the dragon egg. The potion seeped in, gradually forming a small dragon in the egg.

"How?" Hagrid watched Calvin's every move nervously, not that he didn't believe Calvin's level, but that he wanted to raise a dragon too much.

"No problem," Calvin stood up and patted the dust off his body, "the little dragon is very mature, and it will break out of its shell in a few days." ”

Hagrid jumped up excitedly: "Ha, that's great. Immediately, Calvin's blood-red eyes were staring at him.

"Oh, I mean, kind of bad. After all, someone else has already found out that I have a dragon. ”

"It doesn't matter, Hagrid." Calvin expertly poured himself a cup of hot tea.

"Professor Capet, the Malfoys have a good relationship with the Minister of Magic, and if he denounces Hagrid, Hagrid will definitely be captured in Azkaban. Hagrid, you better get rid of this trouble before it's too late. Ron reminded Calvin.

"No, I can't," Hagrid choked, "it's too small, and without me taking care of it, it's going to die." ”

"I don't have a bad relationship with the Minister of Magic. Hagrid, I have a solution, I'm building a new magical beast sanctuary these days, and you can keep the fire dragon with me, so you can go to see it at any time, safe and secure. Calvin spoke his solution.

Hermione thought for a moment and muttered in a low voice, "I remember that there are no magical animal sanctuaries in the UK. ”

"I've built it these days, Hermione. You can invite the three of you to play during the summer vacation. ”

Hagrid's eyes lit up, "It's a good idea to send a sample in the reserve, Calvin." But I'd like to send it over after it's been born for a while, okay? ”

Hagrid looked pleadingly at Calvin, it was his dream to raise a dragon.

Calvin put the teacup down and looked straight at Hagrid solemnly, making Hagrid feel uncomfortable.

"I, I'll give it to you right away, don't raise it......" Hagrid said a little nervously.

"Hagrid, these are minor questions," Calvin said softly, "I'm interested right now as to how you got this dragon egg. ”

Hagrid said stiffly, "I won it by playing cards with a guy in Hogsmeade. ”

"What time? And with whom? What else did you say besides playing cards? Calvin asked.

"A few days after Halloween, I won a game of cards at Hogsmeade's Pig's Head with a stranger who claimed to be Greek, and I don't know anything else. As for what was said......" Hagrid carefully recalled the events of that day, "I really can't remember, I got drunk that day. It was already daylight when I woke up, holding a dragon egg in my arms. ”

"Tsk," Calvin didn't hear any useful information, a little disappointed, and then took out his wand and asked, "Mind if I use some magic?" ”

Hagrid frowned, "Was that important that day?" ”

"It's important." Calvin nodded.

"Well, come on." Hagrid gritted his teeth and agreed to Calvin's request.

Calvin took a crystal ball from his sleeve and placed it on the table, placed his wand near Hagrid's temple, pulled out a silver ribbon, and placed the ribbon in the crystal ball.

Calvin looked up at the three Harry who were stunned, and wanted to kick them out, but then he thought about it.

"You are not allowed to say what you see next." Calvin sternly warned the three of them.

The three of them nodded their heads in understanding.

Calvin then tapped the crystal ball with his wand, and the white ribbon inside spun rapidly, and soon a clear picture appeared.

"It's like, a work of alchemy that I know." Hermione said curiously.

"Meditation basin, but I changed it to a meditation ball."

The heads of the five men crowded in front of the crystal ball, trying to figure out what had happened that night.

Soon Hagrid is seen playing cards with several wizards.

Several people played cards while boasting about their great achievements.

The middle-aged wizard across from Hagrid was a smuggler who was bragging about his smuggling deeds.

Said that he had just returned from Greece and had a lot of good things.

"Helbo's relic, one of the most famous dark wizards in history, took a lot of effort to get my hands on it."

"And the Magic Codex of Plato and Socrates, which I found in a temple."

Calvin sneered at his face, he had all the remaining Plato and Socrates' magical codex in the world, and this smuggler still had a real ghost in his hands, and he didn't make drafts when he lied.

"Of course, there is also a dragon egg, tsk, but unfortunately there has been a lot of trouble in the UK recently, and this dragon egg has smashed my hand." The smuggler said regretfully.

As soon as he heard the dragon egg, Hagrid's spirits lifted.

When the game was over, Hagrid invited the smuggler for a drink.

"This wine is really good!" The smuggler drank a full glass of rum and said, "Thank you, friend, what do you do?" ”

"Me? I'm a Hogwarts Hunting Ground Warden. Hagrid poured a large glass of mead and smacked his lips and said, "Anyone who knows me knows this. ”

"Hunting grounds? I've dealt with a lot of hunting grounds, you know, and they sell interesting stuff once in a while. The smuggler began to boast again, "What about you, is there anything good?" ”

"What are you asking for?" Hagrid's cheeks were already a little drunk.

"Tell me, there are really good things, and the price is negotiable. If you don't believe me, I can ask you for a drink or give you some Galleons. The smuggler bought a bottle of whiskey from the counter and poured Hagrid a large glass.

"I heard, Hiccup, I heard, you have a dragon egg." Hagrid finished his whiskey, getting more and more drunk.

"Ah, I have a dragon egg, and the Ministry of Magic has been investigating it strictly, and I haven't been able to make a move."

Hagrid was a little excited, and said excitedly, "If I can, I'm willing to ......"

"Let's play." The smuggler said, "If you can beat me ten times, I'll give you that dragon egg." If you lose once, give me 10 Galleons. Of course, if you lose to me ten times, the dragon egg will also be given to you. You know more than a hundred dragon eggs. ”
