"This..." Mr. zebu looked at the sudden opening of the cave in surprise and muttered, "I've never heard of such a thing..."

"Come on, let's go to the secret room."

They took out lighting tools such as flashlight, mobile phone or watch flashlight and walked down the stone steps of the dark channel.

White bird police department and Maori xiaowulang opened the way in front, followed by Bai Yan Zhenyu, walking in the middle to protect women and Conan, and finally siruofu and others.

"By the way, Miss Xia Mei,"

On the way forward, siruofu suddenly came to Xiamei in Osaka and asked, "why is the password [magician at the end of the century]?"

"Well, I think it may be because of the title of my great grandfather!"

Sakazaka Xiamei tilted her head and explained, "when my great grandfather was 16, he once participated in the 1900 World Expo, performed Doll Magic at the World Expo, and then lived in Russia."

"I see."

Maori Kogoro, holding a lighter for lighting, suddenly realized: "1900 was indeed the end of the century. No wonder your great grandfather won such a title."

Before long, they walked down the narrow steps and came to a much more spacious underground tunnel.

"Wait, stop."

Just after walking here for a few steps, Bai yanzhenyu suddenly heard a sound. He hurriedly wanted to see a fork not far away and reminded him, "be careful, there seems to be something moving over there?"

"Is it Shi kaobing?" Maori xiaowulang and others were surprised and quickly illuminated them with a flashlight, but they didn't find anything.

"I'll have a look!" Conan acted recklessly again. When everyone reacted, he had disappeared into the dark fork.

"Conan!"

Xiaolan was worried about Conan's safety. Just as she was going to chase him, she was stopped by Bai yanzhenyu and white bird police officers.

"Xiao Lan, you and your uncle stay here to protect everyone. Let's find Conan."

Baiyan Zhenyu gave a solemn order, looked at Officer bainiao and chased up cautiously.

However, not long after Bai yanzhenyu and officer bainiao entered the fork, the dry general at the end of the team found that a figure seemed to flash in another fork, so he went to check the situation. As a result, he saw that Shi kaobing, who was preparing a gun, was killed by the other party with a silencing pistol.

……

In the tense waiting, Baiyan Zhenyu and others soon returned, and also brought back the three groups of ash yuanai and bu Mei.

It turned out that after Bai Yan Zhenyu and others entered the castle, bu Mei's Trio also pestered ash yuanai for treasure hunting exploration. As a result, when exploring a tower, they inadvertently touched the mechanism and fell into the underground tunnel. Then, when looking for a way out, they created what Bai Yan Zhenyu heard.

After Bai yanzhenyu explained the reason to Mao lixiaowulang and others, they continued to move forward in the song of the Bumei trio. At the end of the tunnel, they saw a huge stone gate engraved with strange symbols and bird patterns.

On the left and right sides of the stone gate, there are some symbols that you can't understand. In the center of the stone gate, there is a strange bird with big wings.

The strange bird has two heads, each in the opposite direction, but together they bear a crown inlaid with many precious stones.

"There's no road ahead?" Maori xiaowulang looked at the stone gate in front of him and doubted, "are we going the wrong way?"

"It's impossible. There's only one road in this place, and since it's a door, there must be a mechanism to open it."

Bai yanzhenyu shook his head, carefully looked at the pattern on the gate and reminded: "the pattern above is a double headed vulture, which is a symbol of the Russian emperor. The picture behind the crown should be the sun. You can try to illuminate the crown of the double headed vulture with a flashlight..."

After hearing Bai yanzhenyu's words, the white bird officer adjusted the beam of the flashlight and shone the light on the crown of the double headed vulture.

Under the light of the flashlight, the originally dark gem on the crown reflects the fascinating dazzling light at the same time.

"Click... Click..."

The originally calm tunnel sounded the sound of far rotation of gears, and then a piece of ground in front of the stone gate sank downward, showing a new channel.

"The entrance is here..."

"What a powerful mechanism..."

"What a wonderful design..."

Everyone was amazed at the mechanism designed by Miss Xia Mei's great grandfather, Mr. Xi Yi. Then they carefully moved on and finally came to a room with an oval roof.

There is a high platform similar to the altar in the room, with a Western coffin in the center, and behind the coffin are three stone statues of angels with a sense of religious ceremony.

"Wow, we seem to be in an egg?" Bu Mei exclaimed, and expressed the feelings in everyone's heart in a naive tone.

Maori Kogoro found that there were oil lamps in the room, so he lit them one by one with a lighter to light up the dark stone chamber.

After adapting to the bright environment, Bai Yan Zhenyu, white bird police officer and Maori xiaowulang walked to the middle of the high platform to check the strange Western coffin.

The white bird officer gently touched the lid of the coffin and judged, "it's very similar to the shape of the German coffin, but the material used is wood."

In front of the coffin, there is a huge gold-plated copper lock, which is also carved with strange patterns similar to the style of the huge stone gate.

Seeing the big lock, Bai yanzhenyu suddenly thought of something. He turned to xiangban Xiamei and said, "Miss Xiamei, can you take out the key in your bag? I think it may be used to open the coffin."

"Ah? I see."

Xiangban Xiamei was stunned first, then reacted, took out the key from her bag, walked quickly to the coffin and tried to open the copper lock.

"Click."

Not out of Baiyan Zhenyu's expectation, the copper lock was suddenly opened by xiangban Xiamei.

"Miss Xia Mei, can you open it?"

Not surprisingly, the coffin is likely to be the remains of xiangban Xiamei's relatives. Therefore, before deciding whether to open it, everyone politely consulted xiangban Xiamei.

"This... Can!"

After a brief hesitation, xiangban Xiamei nodded and agreed to open the coffin to see what was inside.

"Uncle, step back and I'll come."

Baiyan Zhenyu worried that there was a mechanism designed by Mr. Xiyi, so he asked others to stay away from the high platform before carefully lifting the lid of the coffin.

After the coffin was opened, there was no dangerous mechanism in it, so everyone gathered around curiously to check the inside of the coffin.
