Since it was a coffin after all, Uncle Mori consulted Natsumi Kosaka before opening it. At Natsumi Kosaka's signal, Uncle Mori opened the coffin with both hands by himself.

The coffin was made of stone, so its weight is not an issue. The fact that Uncle Mori was able to open it by himself, and that he didn't show any signs of fatigue afterward, shows that Uncle Mori's strength should not be underestimated.

Inside the coffin was a skeleton, with an egg placed on its chest.

Natsumi Kosaka believes this must be her great-grandmother. In the ancestral tomb in Yokosuka, there is only her great-grandfather. She guesses that because Natsumi Kosaka's great-grandmother was Russian, she could not be buried in the ancestral tomb.

Although Sirius was large, he was very polite. He stepped forward and said, "Miss Xia Mei, perhaps the timing isn't right, but may I take a look at the egg?"

Natsumi Kosaka didn't mind and reached out to take the egg out of the coffin.

This egg is completely different from the Suzuki family's eggs; it is entirely red with gold flowers as decoration, making it quite luxurious.

However, to Sileof's surprise, the egg was empty.

The whole egg is just a shell, with nothing inside except a few holes.

After hearing this, Ai guessed and said, "It's like a nesting doll, you probably need to put another egg inside."

When Shiratori arrived, he brought a bag with him. He took out the egg from the Suzuki family's bag and said with a smile, "I borrowed it from Chairman Suzuki a long time ago."

Uncle Mori squinted and leaned closer to Shiratori, their faces almost touching. Uncle Mori said, "You didn't steal it, did you?"

Shiratori panicked slightly, but put on a smiling face: "How could that be?"

Kouyu was suspicious of Uncle Mori's behavior. He wondered if Uncle Mori had recognized Shiratori as Kid in disguise, or if it was just a coincidence. He felt that Uncle Mori was not as simple as he seemed.

Sileof took the egg and placed it inside; sure enough, it fit perfectly.

Uncle Mori was about to exclaim about the large gem on the egg when he took it and discovered that it was just ordinary glass.

Conan's mind started working.

Kōyū yawned and stepped forward, saying, "Officer Shiratori, could I borrow your flashlight? Mr. Sylph, could you lend me the egg?"

Guangyou placed the flashlight into a recess in a stone platform in the center of the stone chamber, and after instructing everyone to blow out the candles, he placed the egg into the stone platform.

Conan knew what Kōyū was thinking just by seeing his actions, and slapped his palm: "Damn it, he beat me to it again."

When the egg was placed on the beam of light from the flashlight, golden light instantly flashed from the bottom of the egg, spreading upwards along the egg's pattern.

As the golden light converged at the top of the egg, the entire egg emitted a red glow and gradually became translucent in the astonished eyes of the onlookers.

The emperor doll inside the egg in the Suzuki family's house gradually rose.

Everyone was amazed. It was truly amazing that such a mechanical operation could be accomplished using only light.

What happened next was even more amazing. As the emperor doll rose up and turned the pages of the book, a beam of light appeared at the bottom of the egg. After several refractions, the beam of light converged on the book in the emperor doll's hand.

Instantly, the book's structure allowed the beams of light to connect directly with the glass surrounding the egg. Finally, countless beams of light converged at the top of the egg, and the largest piece of glass on the top of the egg emitted a bright light.

Countless beams of light shone through the glass, each beam striking the walls of the stone chamber at regular intervals, displaying an image that was incredibly lifelike.

Everyone praised the scene.

Guangyou, too, couldn't help but exclaim in admiration upon seeing the scene: "A masterpiece of craftsmanship, truly worthy of being called the magician of the end of the century."

Ai's eyes flickered slightly; she was equally stunned by the scene: "This is the true Egg of Memory."

In China, a translucent mirror was unearthed. It was a bronze mirror from the mid-to-late Western Han Dynasty. The translucent mirror got its name because the images and text on its back could be projected onto the wall when sunlight shone on it.

This technique is said to have been lost during the Song Dynasty, and it was only in modern times that a copy was successfully reproduced using technology.

Experts speculate that this technique is created by using various complex methods to produce a corresponding curvature between the mirror surface and the pattern on the back of the mirror.

With the help of the magic mirror, Natsumi Kosaka finally saw her great-grandmother. The woman in the picture looked very much like Natsumi Kosaka, with a gentle and graceful air about her. From her movements and expressions, it was clear that Natsumi Kosaka's great-grandmother was definitely a highly cultured noblewoman.

Looking at the portrait of her great-grandmother, Natsumi Kosaka said with longing, "That's my great-grandmother. I've finally met her."

After a while, the light faded, and the egg returned to silence, as if nothing had happened.

Sylph pondered for a moment, then picked up the egg and said to Natsumi Kosaka, "This egg belongs to Mr. Kiichi, no, it should be called a great legacy of Japan. The Russian government has decided to relinquish ownership of it, so it will be more valuable for you to own it."

After saying that, Sileof held the egg in both hands and handed it to Natsumi Kosaka.

Upon seeing this, Guangyou's eyes were filled with admiration: "This is what a true lover of art is like."

Sirius's expression showed no greed, but rather determination and a love for art.

With this technology, selling this egg for over a billion yen would be very easy. If it were auctioned, it probably wouldn't even fetch a few billion yen.

Moreover, if this egg were placed in an art museum, it would definitely be a prized possession.

Kōyū couldn't help but think more highly of Sileof, who was able to hold onto his passion despite the temptations of money and fame.
