With extraordinary comprehension, I built a floating city at Hogwarts.

It can be described as a rather luxurious indulgence.

Of course, they don't need those 2.9 now.

There used to be only one painting on the wall of the bath, framed in gold. Hermione remembered that the painting depicted a large ship cutting through the waves, with a man dressed in 17th-century naval officer's attire standing at the bow. He looked somewhat like Jaina and was said to be her father.

This painting is incredibly lifelike, vividly depicting the warship's heroic spirit as it cuts through the waves; it is indeed Levin's work.

And now, there is another portrait beside the big ship, the same one she gave to Levin yesterday, framed in the same way.

Hermione, while feeling shy, was also secretly delighted.

"Alright, stop looking at that." Seeing the girl still hesitating by the pool, Levin urged her on.

"It's not like we haven't seen this before, hurry up and get down."

Chapter 354 The Secret of the Golden Egg

After a fierce internal struggle, Hermione finally wrapped herself in a towel and went to the bathtub.

But she still insisted, "You...you turn your head away, you're not allowed to look!"

"Okay, okay, I won't watch."

Having come this far, Levin had no intention of getting bogged down in the details and obediently turned his head away.

The girl immediately walked to the edge of the bathtub, quietly took off her towel, and, like a mermaid, blushed and cursed herself for being shameless enough to actually agree to this absurd request.

Suddenly, Levin's voice came from the surface of the water:

"Are you done yet? Can I turn around now?"

"Okay, but you have to promise me you won't look around or dive underwater!" The girl surfaced, laying down the three rules.

"Alright, alright, I won't dive then." Levin turned his head and slowly walked towards the girl, behaving very properly.

Hermione was finally relieved.

However, when she looked up, the sight before her made the girl dizzy and mesmerized.

Even though she had seen the boy's body before,

But this direct encounter with the 08 still deeply shocked her.

She saw a handsome boy walking towards her in the water, his broad chest and strong muscles displayed directly before her eyes. Drops of water slid down his muscle lines like glistening pearls, making her blush and her heart race.

Oh no, it’s a heart-pounding feeling.

In the brief moment she was stunned, Levin had already come to his side and sat down with him along the edge of the pool.

"What, are you stunned?"

Levin waved his hand in front of her eyes and said with a laugh.

"Who...who's staring like a fool?" Hermione turned her head and said sweetly, "I'm not...not at all smitten..."

This attempt to cover up the truth amused Levin.

Hermione realized her mistake and immediately submerged half of her head in the water.

Fortunately, the steam rising from the water's surface and the white mist obscured her face, preventing Levin from seeing the blush on her cheeks.

Her mind was filled with Levin's pectoral muscles, and she kept silently repeating to herself:

I need to think about something else and shift my focus.

Correct,

Golden egg!

It hasn't been cracked yet.

Hermione gazed at the vast bath before her, her mind racing with a jumble of thoughts.

Golden egg...screaming...water...

At that moment, a piece of Muggle knowledge I had once learned flashed through my mind:

"Sound is a wave produced by the vibration of matter, and it needs a medium to travel in order to be heard. Sound travels at different speeds in different media, which causes the phenomena of sound reflection and refraction, and the amplitude and frequency of sound will also change in this process."

Thinking about this, the girl seemed to grasp something and fell into deep thought.

"The sound from the golden egg is too shrill. Would it be clearer if we changed it?"

"Changes in the amplitude and frequency of sound mean that the sound heard in the ear changes... The inside of the human ear is a closed space, and it remains a cavity even when submerged in water. So, when sound travels through water to the ear, doesn't this involve refraction and reflection? Wouldn't that change the sound?"

Suddenly, as if she had thought of something, she stood up abruptly.

Large swaths of skin, as white as jade, were exposed to the air, and Levin saw them.

But Hermione didn't pay attention, or rather, she was so lost in thought that she hadn't considered it at all. She reached out and took the golden egg that Levin had brought from the platform not far away, then returned to the water and pondered for a while.

Hermione sank the golden egg to the bottom of the water, and then tried to open it.

The next moment, what emerged from the golden egg was no longer a piercing shriek, but a gurgling song, which came from underwater, though she couldn't make out what it was singing.

But that's enough, because it proves that opening the golden egg underwater is the right way.

"Great! I know what's going on!" Hermione cheered.

"Congratulations, Hermione, you've finally found a way to open the golden egg," Levin said, clapping his hands.

"Thank you, Levin! Thank you for the tip."

Hermione looked at the boy with emotion, and then she realized her problem.

At this moment, she stood naked from the waist up in the bathtub, holding the golden egg in her hand.

Seeing Levin staring at her, Hermione screamed, released the golden egg, covered her breasts, and quickly slid into the water.

"I didn't see anything!" Levin tried to cover up his mistake.

Hermione submerged in the water, only her head showing, and her face had never been so red.

So Levin quickly changed the subject: "Now that you've cracked the secret of the golden egg, why don't you let me hear it too?"

The reason was so plausible that the girl couldn't refute it, so she could only whisper, "But... that can only be heard underwater."

"Then let's listen underwater," Lai Wenming asked knowingly. "Is there anything wrong with that?"

"Then stick your head in the water!" she warned. "And don't look anywhere else!"

Levin nodded quickly, then submerged himself in the water.

Hermione also dived down, opened the golden egg, and heard strange sounds coming from inside, as if they were singing in unison.

Look for us!

Where our voices rang out,

We cannot sing on the ground

When you search, please think carefully.

We stole your most beloved treasure.

You only have one hour.

To find and reclaim the items we took,

After an hour, all hope was lost.

It has completely disappeared.

Never to appear again.

The music stopped, but Levin didn't hear it at all; his eyes were elsewhere, not on the golden egg.

Hermione noticed this and was about to get up and leave when she felt a pair of hands grab her and drag her down.

The golden egg continued singing that song as it sank to the bottom of the water, but no one cared what it was singing anymore.

Taking a bath is clearly a very relaxing and enjoyable activity that relieves fatigue.

But after taking a bath with Levin all night, Hermione felt even more exhausted.

However, this was not without results.

At least today, through her own 830 experiments, she has fully figured out why felines like Crookshanks don't like taking baths.

This will be a landmark discovery in human biological history, and it is truly cause for celebration.

Feeling weak all over, she was now nestled in Levin's arms, squeezing onto the sofa with the boy, enjoying the warm firelight while pondering the song inside the golden egg, trying to decipher its mystery.

This is actually a relatively simple riddle; the content of the second challenge is hidden in this song.

"The golden egg can only sing on land, and its song can only be heard in the water... Is the target we're looking for in the water?"

She murmured softly, trying to clear her mind.

“The only place near Hogwarts is the Black Lake,” she muttered to herself, searching for the answer in the conversation.

"They stole my most beloved treasure... I only had one hour..."

"Do we need to find the stolen items within an hour?"

Hermione raised an eyebrow slightly, a confident smile on her face: "The only ones who can sing in the Black Lake are mermaids. So this mission is about a warrior's most treasured possession, which has been left in a mermaid village, and we have to get there to retrieve it."

"You guessed right." Levin patted the girl in his arms encouragingly.

This riddle proved no challenge for Hermione; from initial thought to understanding the task, the entire process took less than five minutes.

But one question remains unresolved:

"My most beloved baby..."

She murmured again, her eyes narrowing slightly: "What could this mean?"

Chapter 355 The Alicorn

With Levin's help, Hermione's investigation into the secret of the golden egg finally yielded results.

In high spirits, the girl fully satisfied Levin's various strange fantasies during the holiday, allowing him to explore the deep secrets of the Animagus.

Unfortunately, compared to the Animagus's "research," the exploration of creating plant spirits remained completely fruitless.
