On the way, with the addition of several members of the detective group, the atmosphere of the underground secret room is more lively, but the conspiracy or battle hidden in the dark is brewing or has happened!

Because everyone had flashlights, and now there were a few more children, Mori volunteered to be the striker, so that Kaito, dressed as Officer Shiratori, took care of the tail and the children were protected in the middle.

"Huh, where's Mr. Qianjiangyi?" After walking for a while, Kuaito realized that there was one person missing,

"Yes, did any of you see him?" Maori also stopped and looked at the crowd.

"Sorry, we didn't notice. Natsumi Kasaka and her old butler looked at each other and replied.

"Me too!" the rest chimed in.

"Wouldn't he have quietly left and gone up on it again?" Maori guessed.

"Shall we go back to him?" Kaito looked at the group.

The atmosphere was quiet, and everyone had their own answers, but no one spoke first.

"Everyone has already arrived here, so let's move on, as for the things in the castle, I think Mr. Qianjiangyi is not a child anymore, he should know his own proportions. As an old butler, he naturally knew everyone's worries and their own needs, so after discussing it with Kasaka Natsumi, he spoke to everyone.

"So, let's move on. With the help of the castle owner, the group continued to walk ahead.

"No way?" Mori hadn't gone far, looking at the drawing on a door in front of him.

"Are we on the wrong track?" the crowd discussed.

"I don't think so, there's only one way we've ever been here!" said Kaito.

"So, there should be a mechanism here?" the crowd speculated.

"But what does this picture mean?" the crowd also looked at the painting on the door in front of them.

"There are so many birds in the painting~" Ayumi and the others looked at the part illuminated by the light.

"But only the top two big birds have two heads. 」

"And he's wearing a crown!" said the detective group.

"Two-headed vulture, the Emperor's banner!" Xiao Ai said, glancing at him.

"yes, is it the sun behind the crown?" Conan also looked at the door painting.

"Sun, ray~" Conan said to himself, as if he had thought of something.

"It's really self-inflicted, and you can't live. Xiao Bai, who originally stepped forward, was about to answer something, but in Conan's self-talk, when Xiao Bai looked at Xiao Lan and looked at Conan, he could only shrug his shoulders and did not make any answer.

"Officer Shiratori, please focus the light of your flashlight on the crown of the two-headed vulture!" Conan said, gesturing to the crown.

"Okay!" Kaito nodded, then adjusted the focus of the flashlight and shone it on the crown.

The crown emitted a burst of light, and a sound came from the quiet cave.

"What is this?"

"I guess the mechanism was triggered!"

Although I was a little panicked at first, it wasn't once or twice that I came here, so although I was a little flustered at first, it didn't take long to stabilize my emotions.

"There's a way!" looked at the staircase formed in front of them, and the detective team was stunned.

"That's amazing!" and then several people looked at each other excitedly.

Then the group descended the stairs and walked inside.

Entering the room, the space inside is oval-shaped, and in front of it, a rectangular object can be vaguely seen in the middle, and the sound of running water can be heard on both sides.

"It's like we're in an egg. Ayumi looked around by the light.

"It's like a coffin. Mori stepped forward, looked at the candles on the left and right, and after lighting them, Kaito walked to the front of the rectangular object.

"Western-style styling, probably wood. Maori stepped forward.

"However, this lock is really big, but this hole~" Maori looked at the keyhole.

"Miss Natsumi, the key. Conan shouted at Natsumi.

"Yes, Miss Natsumi, please give me the key. Maori turned back to Natsumi.

"Okay!" Miss Natsumi stepped forward and took out the key from her bag and gave it to Maori.

"That's right!" the key was inserted into the hole, and the lock was opened.

"Sure enough, it's the key!" Miss Natsumi looked at the lock that had been removed, not knowing what she was thinking. But the nervousness was palpable.

"Can you open it?" Everyone present seemed to have an answer, and Mori asked Natsumi.

"Yes!" Natsumi nodded.

Then, Mori and Shiratori stood on either side of the coffin and looked at each other, then nodded, and the two of them worked together.

Because the coffin had not been opened for a long time, a lot of dust had accumulated, and the people lying inside were only dry bones.

"A corpse and an egg. The crowd looked inside the coffin.

"The body is holding the egg, I think, this should be your great-grandmother, Miss Natsumi. Maori looked at Miss Natsumi.

"Well, I think so. Miss Natsumi nodded.

"Miss Natsumi, maybe the timing is a little wrong, can you show me that egg?" Siru Ovchennikov stepped forward.

"Please!" Miss Natsumi took out the egg from the coffin and gave it to the other party.

"There's a little hole at the bottom, but it's empty inside. I think this should be another egg of the Emperor's Easter Egg. It's a pity that the rest can only be confirmed by looking at the Suzuki consortium to get another egg. Siru Ovchinnikov shook his head.

"I don't think it's that troublesome. Kaito took off his satchel and pulled out another egg.

"I was worried that this would happen, so I borrowed the eggs from Mr. Shiro Suzuki. Seeing that everyone was looking at him, Kaito explained.

"Sure enough, it's a set!" Siru Ovchinnikov took the egg and put it inside.

"But nothing happened. Maori looked at the egg in front of him.

"Could it be that this egg has the same mechanism as the people outside?" Ayumi began.

"yes, this egg must have a mechanism. 」

"Maybe like a door, there's something cool going on when you shine on the light. The detective group said one by one.

"If you look closely, it doesn't seem to be a diamond. Maori watched the egg closely.

"There's a platform here!" While Maori and his party were still studying the eggs, the detective team and Conan and his party spotted something and pointed not far away.

"This ......" Everyone looked at the pillar in front of them, and then at the egg in their hands.

"Looks like it can be put in!" Ayumi said, looking inside.

"It seems that you can put something down there, too!" Xiao Ai pointed to the bottom of the stage!

"Put it in!" I saw Siru Ovchin Nikov look at Miss Natsumi, as if to see the other party's attitude, and after the other party nodded, he put the egg into the pillar.

"Uncle, please blow out the candle, Officer Shiratori, please put the flashlight under the pillar!" Conan said to the crowd!

In the cave, everyone turned off their flashlights and nervously watched Kuaidou put the flashlight under the pillar!

The light is transmitted into the pillar, and the light visible to the naked eye swims like a vein, and then gathers and disperses.

The magic of the end of the century is about to be presented in front of everyone's eyes!
