Although he couldn't take the final step due to his health, he actually played the most games with Ai.

The two of them tried almost every kind of mini-game.

Binding and feeding are child's play for them.

"How do you know she's unhappy?" Ai raised an eyebrow and looked up at Yuzuru.

Seeing Ai's smiling eyes, Yuzuru remained silent.

Whether a toy is happy or not is something its owner, who plays with it, knows best.

"No!" Yuzuru made a quick decision in his mind.

He'll try out the toy later to see if it's fun and whether playing with it really brings him joy.

After all, only practice can reveal the truth!

At the same time, at Yuzuru's residence.

The dimly lit basement was unusually quiet, as if even the air had frozen.

On the table, the large bowl of spirit rice porridge that Xiao Ai had brought was now empty, with only two small, shimmering purple balls remaining, gently swaying and emitting a faint glow.

...

After a few minor hiccups, the subsequent search proceeded very smoothly.

Natsumi Kosaka led everyone through each room, while the group also checked each room to ensure there were no hidden mechanisms or secret passages.

Finally, they arrived at Mr. Kiichi's office.

Conan looked curiously at the photos hanging on the office wall, especially those belonging to Mr. Kiichi.

"Sister Xia Mei, why are there only photos of your great-grandfather here, but not your great-grandmother?" Conan asked curiously.

"You mean this?" Natsumi Kosaka gave a sweet but slightly troubled look. "I don't have any of them. I don't know what my great-grandmother looked like."

"Is that so..." Conan found it a little strange.

The detective's intuition told him that things weren't so simple.

"Hey, that man is Rasputin!" art dealer Gan Jiangyi suddenly shouted, pointing at a photograph.

"Yes, it really is him."

"Yes, it also has his signature on it."

Everyone gathered around, their eyes fixed on the photograph.

Xiao Lan blinked when she saw everyone discussing this person, "Rasputin... Nan, who is this person?"

"He is..." Hanyu Nan was about to speak when he was interrupted by Mouri Kogoro.

Kogoro Mouri stroked his chin and pondered, "I remember this guy was a big bad guy!"

Pu Siqinglan, who had been silently following behind, narrowed her eyes slightly, a subtle and unsettling glint in them.

"The sorcerer Rasputin, the culprit who caused the downfall of the Romanov dynasty, once held power for a period of time, but was eventually assassinated by Prince Pov, Grand Duke Dmitry, Senator Prishkovich, and others."

Officer Shiratori walked up to the photo, looked at it carefully, and continued, "Later, his body was found in the river, and his right eye had been gouged out by someone."

"One eye?" Conan realized something was wrong.

“Oh, right!” Officer Shiratori said, turning to look at Yuzuru with a hint of mockery in his eyes. “I heard he also knows hypnosis, especially effective on women. It’s said that all the noble girls in Russia at the time had relationships with him.”

Upon hearing this, Yuzuru rubbed his nose helplessly.

Just say it, why are you looking at yourself? You don't know hypnosis.

Besides, I don't only like young girls!

"Ahem, Uncle Mori, there's a breeze blowing up from down here," Yuzuru said, ending the conversation.

Conan immediately realized something was wrong with the smoke, and with a nimble leap, he snatched the burning cigarette from Kogoro Mouri's hand.

"There is a hidden chamber down here."

Everyone was shocked to hear this.

Conan lay on the ground and carefully felt around for a while before easily lifting a hidden floor panel, revealing a Russian combination lock inside.

Yuzuru looked at the scene before him and couldn't help but twitch his lips.

I initially thought it was just a dramatic adaptation of an anime, but it turns out it's true in real life too.

Do this family never mop the floor?

It's quite absurd that such an obvious mechanism hasn't been discovered yet.

"Barushenigukadame".

After several incorrect password attempts, Natsumi Kosaka remembered a phrase she had heard as a child.

Could this be it?

“It’s Barushepnik, Kanzhimei,” Pusiqinglan said, looking at the Russian ambassador, Siryuv, whose name couldn’t be translated.

Upon hearing this, Sileo clapped his hands excitedly and shouted, "Yes, that's it! If you translate it into English, it should be..."

"The magician at the end of the century."

Akemi peeked her little head out from behind Yuzuru Hanyu.

When it comes to translating languages ​​from various countries, it's a piece of cake for them, who have experienced the art of translation.

As Sileof entered the correct answer on the combination lock—"The Magician of the End of the Century"—a slow, whirring sound of a mechanism turning began to emanate from underground.

Yuzuru gestured for Natsumi Kosaka to take a step back.

The next moment, the floor cracked open, revealing a spiral staircase leading underground.

Natsumi Kosaka first gave Kusunoki Hanyu a grateful smile, then looked at the dark passageway in surprise and said, "So there really is a secret room under our house..."

"You guys, don't run around when we go down there. Stay close behind me and behave yourselves!" Ai shook off Yuzuru's hand and turned to the three little ones who were already thinking about what to buy after finding the treasure. She said seriously.

"Okay, Ai," Genta, Mitsuhiko, and Ayumi replied in unison.

“Okay, Ai!” Professor Agasa replied.

Ai: "..."

After giving Professor Agasa a look of exasperation, Ai turned and followed the others down the aisle: "Everyone, follow me!"

After descending the stairs, the underground space was much larger than I had imagined, resembling a giant maze.

The group, carrying different lighting tools, groped their way forward in the darkness.

The children were quite happy, skipping and jumping in the middle of the group, and even singing nursery rhymes.

"Let's go, let's go, let's go, let's hold hands, let's go, let's go, let's go on a picnic together amidst the green hills and clear waters..."

The clear, innocent voices of children echoed back and forth in the empty underground space.

"Go, go, go, go, go..."

Akemi, feeling childlike, hummed along for a few lines before looking at Ai and saying with a grin, "It sounds really good! Ai, why don't you sing along? Don't be a loner!"

"hehe……"

Ai gave a speechless twitch at the corner of her mouth.

She realized that her sister was now truly treating her like a child.

Clearly, he knows less than I do in terms of both knowledge and skills.
