After saying this, Gao Yuan suddenly thought of something, and Kudo Shinichi on the side also stopped the idea of going in to take a look, and invariably, the two came to the window of the room, opened the window, and went out of the window!

Coming to the wall facing the bookshelf in the room, from the outside of the room, this is exactly the location behind the house, and this wall is also thickened, so it can accommodate such a passage to the underground.

"I see!"

"That's what happened!"

Takato and Kudo Shinichi said similar words at the same time, and then looked at each other and smiled, but quickly fell into thought.

Back in the room, Sonoko Suzuki had already walked out of the basement, so Takato and Kudo Shinichi walked into the passage.

After the bookshelf was removed, the passage left was the size of a door, and inside was a wooden staircase, and after walking down, the two saw that the basement was not very large, only about a dozen square meters, and the height was less than two meters, it was an empty room with almost nothing - except for a bed!

Very abruptly, in this basement, there is actually a bed!

"How did you get to this room?"

Takato asked Shinichi Kudo beside him.

"It's obvious, because apart from the bedroom upstairs where you've already installed the bed, only this one looks like it's been cleaned."

Kudo Shinichi said, for this, Gao Yuan didn't look at it carefully, after all, when he was going to investigate this villa, it happened that Kudo Shinichi and the three of them came over.

"It seems that there are no other clues, why don't you go up first."

Takato proposed.

"Looks like yes, let's go up and analyze the current clues first."

Kudo Shinichi agreed.

Back in the hall, continuing to sit in his original position, Maoliran asked, "Do you know what's going on?" Shinichi! ”

"yes, why is there a secret basement in that place! It hurt me and I fell. ”

Sonoko Suzuki said distressedly.

"I have roughly figured out why this villa has made strange noises for a year, and how outsiders enter and exit this villa."

Kudo Shinichi said.

"But I don't have any idea what the purpose of this is."

Gao Yuan echoed.

Regarding the conversation between the two people, Mao Lilan and Suzuki Sonoko on the side were incomprehensible.

"Then tell me, why has this villa made strange noises over the past year?"

Maoliran asked.

"Ah, it's actually very simple, I understood when I heard the wise detective say, 'This villa doesn't have this basement on the floor plan.'"

Kudo Shinichi said, then looked at Takato.

"Yes. Since it doesn't exist on the floor plan, but it actually does, it is obvious that someone deliberately dug it up, so it's easy to understand why there has been a strange noise coming from here for nearly a year - because that's the sound of digging a basement! ”

Gao Yuan explained.

"If you understand this, it's easy to understand how outsiders get into this villa."

Kudo Shinichi said slowly, showing a puzzled expression, "But in this case, the whole thing becomes difficult to understand. ”

"yes, it's really hard to understand secretly digging a basement or something for someone else's house."

Sonoko Suzuki echoed, "But what does that have to do with why outsiders can come in?" ”

"After all, Mr. Wise's key can open the door normally, so the lock hasn't been changed, so that's how they came in?"

Maolilan expressed the same confusion.

"Stupid! I all know that outsiders have dug the basement for this villa, how can I still think about this kind of thing when I come in? ”

Kudo Shinichi explained a little speechlessly, "Of course I smashed the wall directly!" ”

Such a conclusion surprised the two girls present.

"Smash...... Smash the wall! ”

"Yes, you see the location of this basement entrance, it is in the outer wall of the house, and the only way to build such an entrance after the villa is built is to smash the wall first! Since the wall was smashed, it is not surprising that outsiders can come in! Just finish the wall after the basement is built! ”

Gao Yuan said.

"And the location of that wall is right behind the villa, surrounded by a fence, where the construction is not visible to outsiders. The strange noise before the combination was made at night, that is, the person digging the basement started the work at night, so that no one would find out. ”

Shinichi Kudo added.

"But what is the purpose of smashing the wall of someone else's villa like this, digging out a basement, and then filling the wall?"

Mao Lilan asked suspiciously.

"That's right, that's what we don't understand at the moment. What's the point of spending nearly a year digging a basement in an uninhabited villa? ”

Shinichi Kudo fell into thought.

"The only clue seems to be the bed in the basement."

Gao Yuan explained.

"There's a bed, what's this? It must have been used by the people who dug the basement to sleep. ”

Sonoko Suzuki said.

"But don't you think it's strange? Why put the bed in the basement when it's going to sleep? Anyway, the whole villa can come and go at will, and it wouldn't be better to put the bed in the villa. ”

"What's more, this bed was obviously put in after the basement had been dug up."

Kudo Shinichi said, and then Takato added, Suzuki Sonoko listened to what they said, and couldn't help but feel a little embarrassed by her previous remarks.

"Huh? It's really strange to say that. ”

"But it's clear that this bed wasn't there for no reason."

Kudo Shinichi said, and then shook his head vigorously, "No, I have to say, from digging the basement to putting the bed, this whole thing can't be for no reason, it's like ......"

"I had to do the same in order to meet any need."

Kudo Shinichi seemed to be short of words for a while, and Takato made up for it.

"That's right! That's how it feels! ”

Shinichi Kudo agreed.

"But it doesn't seem to be any different from not saying it."

Mao Lilan smiled helplessly and said, "After all, no one will be bored enough to do such a meaningless thing." ”

"In other words, doing this in itself should be of great significance, so important that it will take nearly a year and a lot of wealth to do."

Kudo Shinichi changed his mind because of Mao Lilan's words and said, while Takato on the side was still thinking, and then seemed to think of something and spoke.

"Let's not mention the basement first, let's look at the bed, who do you think this bed is for?"

"Huh?"

Moriran and Sonoko Suzuki are puzzled, but Shinichi Kudo seems to be awakened.

"Yes, let's not mention what the purpose of the basement is, but if it's just this bed, it's obviously for whom!"
