After Calvin left the Headmaster's office, he did not rush back to his room, but went to the tower of Hogwarts, where he wandered incessantly.

As night wore on, Calvin had finally found his goal: a tall, shackled, silvery-white ghost covered in blood.

"Barrow." Calvin stepped forward to say hello.

Barrow paused, lowered his head, and looked at Calvin with his blank eyes, "Little Calvin, what's the matter with me?"

Calvin took out a long-horned water serpent gem from his sleeve and pinched it in the palm of his hand, thus floating into the air so that he could talk to Barrow at eye level.

"Barrow, I'd like to ask about Rowena Ravenclaw, about her magic." Calvin weighed his words to make sure he didn't talk about Helena Ravenclaw.

Barrow was silent for a moment, then dragged the heavy shackles on his way and said in a hoarse voice after a while, "Rowena Ravenclaw was one of the best wizards of his time.

She is proficient in all kinds of magic, and although she is not as knowledgeable as the other three founders in many fields. And she also has areas where she excels, and in those areas, her intelligence is unmatched."

Calvin floated behind him at Barrow's speed and asked, "And what magic is Lady Ravenclaw best at?"

Barrow fell into a long silence again, and Calvin didn't dare to ask, so he had to wait for him to speak.

"Alchemy, time, soul, and memory." Barrow slowly spat out the words.

"Souls and memories." Calvin repeated.

"Yes, the wisdom of the Sorting Hat was given by Lady Ravenclaw."

"But I remember the Sorting Hat was a Gryffindor hat."

"Gryffindor just instilled his mind into it, the Sorting Hat is just a mechanical dead thing, and without the Ravenclaw lady's ignition and reinforcement, the Sorting Hat would not have been able to survive as a part of the entire castle." Barrow said.

"Lady Ravenclaw's wisdom in soul and memory is unmatched, and her crown can enhance the wisdom of its wives, can you make it? You can't."

Barrow spoke slowly, but Calvin always felt that Barrow was mocking himself.

It can't be helped, he really can't, he can't even fix it, that's the truth. And the truth is often the most hurtful.

"At that time, wizards who were obsessed with the master-apprentice system jointly attacked Hogwarts, and Lady Ravenclaw did not use offensive spells, so dozens of wizards fell into the most painful memories and committed suicide one after another."

"She also has a bathroom-sized meditation basin where she teaches students she likes."

"Meditation Basin!" Calvin perked up and hurriedly asked, "Where is that meditation basin now?"

Barrow shook his head slowly, "I don't know, it's gone when I get back."

Calvin floated slowly down from mid-air, "Thank you, Barrow."

Calvin turned and ran in the other direction, having already guessed where the bathroom-sized meditation basin might be.

Soon, Calvin was on the eighth floor of the castle across from the Silly Barnabas Tapestry.

He bowed his head and said silently in his heart: ....

Home to the Lady Ravenclaw Meditation Basin.

Home to the Lady Ravenclaw Meditation Basin.

Home to the Lady Ravenclaw Meditation Basin.

Then he walked quickly through the blank wall opposite the tapestry, back and forth three times, and when he looked up again, a blue door had appeared on the wall.

Calvin felt a burst of ecstasy in his heart, there was a play!

He grabbed the doorknob, took a deep breath, and slowly pushed the door open.

Inside the door was a pristine white room, most of which was occupied by a large meditation basin except for a few steps from the door. The walls were carved with the inscriptions that sustained the magic of the Meditation Basin, and Calvin easily recognized several of them, yes, they appeared on Stonehenge.

Calvin stood on the shore and waited for a while, the meditation basin did not respond, he thought he had hit

Opening this room would trigger some kind of magic left by Lady Ravenclaw, but it doesn't seem to be there now.

This made Calvin hesitate. He looked at the pool full of liquid with a mysterious silver glow, hesitated for a moment, and finally jumped into the meditation pool of Ravenclaw like a dive.

Not much time to lose consciousness, Calvin soon found himself standing in a dilapidated wooden house. There were about three or four women standing around, anxiously waiting for a pregnant woman lying on the bed.

Calvin observed what the people were wearing and what they were around, and he probably judged that this was a thousand years ago.

Soon the pregnant woman in bed began to scream, her breathing began to be rapid, and after a period of scrambling, a woman walked up to the pregnant woman with a newborn baby in her arms.

"Mrs. Ravenclaw, you have given birth to a daughter!"

The pregnant woman smiled weakly, "Just call her Rowena, Rowena Ravenclaw."

Then the scene around Calvin changed, and on the banks of a river, the woman who had just been pregnant had arrived with an eleven-year-old girl, and they were sitting on the ground.

The young woman said, "Rowena, from today onwards, your mother will teach you how to use magic. It's your wand, take it."

The young woman handed a wand to little Rowena and continued, "Olive wood, the core of the wand is the feather of the raven, they both represent wisdom, you must be good at using it."

Little Rowena took the wand and asked puzzledly, "Mom, why don't you teach me magic in the village?"

The young woman touched little Royna's long hair, "Child, don't let the people of the village find out that we have magic, or they will kick us out."

"Isn't Chief Smith okay?" Rowena asked aggrievedly, "He's good to us."

The young woman smiled, "No, son, we can't tell anyone about magic except our kind."

"Aren't those villagers our kind?"

"No, they're Muggles, we're wizards. Muggles hate wizards, always."

"Why can't Muggles and wizards live together?"

"Son, why don't you have so much?" The young woman became impatient, "Let's learn our first magic, the Levitation Charm."

Rowena didn't continue, but Calvin could clearly see that the confusion on her face hadn't gone away.

The scene shifts to a village in medieval England. A little boy fell off the roof and was about to fall to the ground when Rowena, about fifteen years old, stepped in and held him up with a levitation charm.

When he returned home in the evening, the restless Rowena told his mother about it, and the mother was so shocked that she hurriedly left the village with her daughter, without even taking much of her belongings.

When they reached the top of a nearby hill, the mother and daughter looked back and saw that their house had been engulfed in flames.

"Why?" Rowena muttered to herself, a crystal tear sliding down her cheek.
