Calvin opened the letter without a hint of magic attached, and quickly read the inexplicable letter.

"Tsk, I think this Mr. Grindelwald has a big misunderstanding of me." Calvin casually placed the letter back on the table.

Grindelwald may have thought of himself as the author of the book written by Royiner, and in his letters he was extremely sarcastic about Calvin, who, no matter how good-tempered he was, could not stand the taunts of an old man he didn't know thousands of miles away.

"What did he say?" Dumbledore asked with interest.

Calvin glanced at Dumbledore and picked up the letter from the table again, "It's all sarcasm, what's 'I have a shallow knowledge of the Muggle world, nonsense, I'm not an expert in Muggle studies;' The attitude towards Muggles is too negative, the lack of courage, and not as good as Carlotta Pinkestone, hell, I don't know any Carlotta."

At this point, Dumbledore interrupted Calvin with a smile on his face, "Carlotta Pinkestone is a witch who is known for advocating for the repeal of the International Confederation of Wizards' Secrecy Act."

"yes, so what does this have to do with me," Calvin snorted disdainfully, "I think Grindelwald has been locked up for too long, and his brain is ruined. And you, Albus, I think you've been so kind to Grindelwald that the first Dark Lord can still have a chance to communicate with the outside world. I'm sure I'm not going to let Voldemort get the same treatment."

Dumbledore still smiled, but simply said, "There's a very complicated story here, do you want to hear it?"

"No, it's just a remnant of the old days." Calvin had little interest in the love-hate relationship between Dumbledore and Grindelwald.

"Well, is there anything you want to talk to Gellert? I can relay it for you." Dumbledore wasn't in the slightest offended by Calvin's attitude.

Calvin raised his eyebrows and said two words, "Please help me bring two sentences, first, I'm not the author of that book. Second, I'm not interested in his theories."

Dumbledore nodded slightly, he was a little surprised that Calvin had such a tough attitude towards Grindelwald.

"By the way, Headmaster Dumbledore," Calvin put away Grindelwald's letter, "I have to tell you something, I'm going to Egypt in the next twenty days."

"To Egypt?" Dumbledore repeated.

"Yes, mainly to do Professor Barblin a favor."

Dumbledore raised the cup of pumpkin juice and said to Calvin, "Then I wish you a safe return."

"Of course, of course I will return safely."

-----------------

Egypt, on the banks of the Nile.

Three days later, at the same time, Calvin and a tightly wrapped Bassida Bablin were walking down the streets of Cairo.

"I said, 'Are you dressed like this?' It's so appealing." Calvin looked strangely at Bassida, who was wrapped in a white gauze and wore a wide sunhat.

A dull voice came from under the veil on Bassida's face, "I'm sorry, but I can't bask in the sun due to my physical condition."

Calvin didn't speak, just disappeared, and when Calvin reappeared, the whole of Cairo was shrouded in a dark cloud, and from time to time lightning streaked by. ….

"Oh, thank you, Calvin," Bascida finally pulled off the clutter of her body, revealing her fair skin, and breathed in the fresh air with moisture, "It's like Thunderbird magic?"

Calvin nodded, "Thunderbird's Weather Spell."

The dark clouds overhead kept moving around Calvin, making sure Bascida wouldn't be burned by the sun.

Bassida, who was dressed in cool clothes, also recovered her vitality and gradually became talkative.

"Are you visiting Cairo for the first time?" Basida noticed that Calvin's attention was distracted, constantly changing the situation around him.

Calvin nodded, "Yes, it's my first time in Egypt, I've been to Greece a lot before, and the Parthenon is as familiar to me as home."

"Oh, yes? Then you have to be careful, the pyramids are much more dangerous than the temples in Greece." Bassida quipped.

The corners of Calvin's mouth curled, "Sounds like you're familiar with pyramids."

"Sort of," Bassida shrugged, "once in a few years."

"Well," Calvin suddenly remembered something, and asked, "Bassida, have you discussed it with Gringotts here when you came to Egypt to explore the pyramids?" When I was in Greece, I remember that the elves were particularly difficult to deal with."

Bascinda covered her mouth and sneered, "As a witch who has lived for three hundred years, there are always some assets, and Gringotts is one of them."

"You opened Gringotts?" Calvin asked in surprise.

Basida didn't expect Calvin to understand it this way, and explained awkwardly, "No, no, I'm just one of the shareholders."

Calvin and Bassida laughed together.

"I invited you this time because the archaeological team has encountered some problems that even I can't solve." Bassida said.

Calvin smiled and nodded, motioning for her to continue.

"In the burial chamber at the lowest level of the Pyramid of Khufu, the archaeological team accidentally discovered a passage to a deeper dark chamber. A winding, steep downward passage protected by a variety of magical traps. The archaeological team didn't even go through the entire passage before the wounded appeared."

"What kind of magic trap is it," Calvin asked, "I have to warn you in advance, I probably won't be able to solve it either."

"It's mostly all kinds of curses, but it's not a big problem. The most dangerous thing is the frescoes on the walls of the passage." Bassida shuddered.

"Mural?" Calvin was interested, it stands to reason that the place with the highest level of magic painting and the most comprehensive development is in the Far East, but now there are murals in the pyramids of Egypt with the ability to damage, which makes Calvin very interested.

"Yes," Bassida said, "the mural is a magical animal that has never been seen before."

Magic painting, magical beasts, this is Calvin's specialty, no wonder Bascida said that she wanted to bring him over.

It appears that a very powerful wizard, possibly a dark wizard, entered the pyramid and built a secret room for himself, laying out intricate traps.

So what's the purpose of doing this? Is it to protect the secret room from the harassment of latecomers, or to use such harsh means to test latecomers.

Or is the very existence of this secret room a trap?

Calvin smiled slightly, remembering the experience of fighting with the dead despicable Helbo in the Parthenon a few years ago after a thousand years.
