Without a helper, there will be many inconveniences, but it is not difficult to move an inch.

- Although there are many maids who take care of the "old lady's" daily life, Nishikawa divides the people into several groups and asks them to go into their rooms at different times of the day and do different things, so that they think that someone else will help the "old lady" wash.

Then she kicked all the maids out while she was sleeping and washed herself, so that no one would see her body that did not match her actual age.

This is not absolutely safe, but there is no other hostess in the family now, only a son-in-law, and a grandson who grew up abroad and is not very close to the old lady.

As adults of the opposite sex, of course, they don't care about whether the "old lady" is an old man or a young person after she takes off her clothes.

Nishikawa has survived like this, and has not been exposed so far.

But today, her good fortune seems to have run out.

- When Shiraishi was asleep just now, she used the secret passage to sneak into the room where the other party was, and put a glass of juice with sleeping pills on Shiraishi's bedside table while the maid she sent showed the high school girl to visit the castle.

I thought I wouldn't see this person again today, but I didn't expect him to not only wake up, but also catch dinner accurately.

Later, after discovering that the black-skinned detective and Shiraishi had actually entered the secret passage, Nishikawa originally planned to activate Plan 3 and sneak attack the two in the secret passage.

Who knew that she was turning around, but she never managed to get around the backs of these two people.

…… The new stranger could not be more familiar with the secret passage than her, and Nishikawa could only explain that these two people were too lucky, or that she was too unlucky.

But Nishikawa didn't give up.

After another failed siege, she came out of the secret passage, ready to rush into another secret passage, and continued to take a shortcut around her back.

As soon as they arrived in the corridor, the other two people found the exit of a secret passage and happened to collide with themselves.

Nishikawa was only a little stronger than her peers, and she didn't have the strength to fight two young men head-to-head - and the situation was worse than she expected, not only could she not fight, but she couldn't even run.

When they were in the secret passage before, Nishikawa overheard part of the conversation between the two and knew that they had doubts about the authenticity of the "old lady".

This time she was suddenly held down by the black-skinned detective, she thought everything was over, but she didn't expect that the little boy who was knocked out and taken away by her before would come in handy.

For these two detectives, the treasure has no value - no one else can take it.

In other words, they must be more concerned about the child's life.

After comprehensively weighing the character of both sides, in line with the principle that the one who has no bottom line wins, Nishikawa felt that she could force them to tell them where the treasure was, and then tell them where the little boy was tied up.

Such a young schoolboy was thrown into the ground after being injured, these two people would definitely be very anxious and go down to look for it first.

When the time comes, you will be able to take the opportunity to rush to the location of the treasure and get the treasure. After that, he used his familiarity with the secret passage to quickly escape - he couldn't block those two people just now, just because it was difficult to go around his back, and if someone else chased him, Nishikawa was confident that he would never be caught up.

The only drawback of this scheme is that if the treasure is too big, it may not be taken away.

But if you are so rich, you must like things that are delicate and expensive. And if it was too big, she must have found it long ago after wandering around the castle for so many years, but she hasn't been able to find any clues to this day, doesn't that mean that it is easy to hide.

Nishikawa thought to herself, she was simply too witty. OK

Desperate life, bitter endure. I thought that today was an unlucky day, not only was the old lady's body seen by the child, but also the detective revealed the true face, and was forced to pull the gate.

I didn't expect that in the end, not only would I be able to fight against the army, but I would also be able to get the treasure I was looking for, which was simply ......

It's so much fun!!

And this kind of happiness that has gone through many difficulties and dangers, with many twists and turns, is not at all comparable to ordinary happiness.

Nishikawa quickly drew up a plan.

She got up and straightened her clothes, ignored the fierce black-skinned detective, and turned to look at the kind young man on the other side who had slipped his mouth and still had some regrets, thinking that this person must be very good at talking and deceiving.

During the conversation, Baishi pretended to be entangled for a while, and first turned over and over a few sentences of "He is still a child", "You must be true to your word", "You will really let him go", and then hesitated to get to the point:

"The clue is the 'old lady' of the Manomiya family who has passed away, because the Western chessboard in the courtyard is ...... Anyway, you're probably not interested in listening to it. ”

Shiraishi saw that Nishikawa's face was really full of eagerness, so he skipped the thought process and directly said: "Anyway, turn that portrait of the old lady to the left, and the entrance to the treasure will appear." ”

Hattori sighed again when he heard this.

For every detective, the process of saying the reasoning ideas and unraveling the mystery little by little is a great enjoyment, but now, Shiraishi has taken the initiative to give up this fun.

He always felt a little bit of a loss and wanted to add an explanation.

But before she could say a word, Nishikawa had already rushed out with a vigorous pace that did not match her appearance at all, and went straight to the castle hall.

"......" Hattori Heiji stared at her back very unhappily, and pulled his legs to catch up - you have to watch and don't let her run away. Although I don't know if she lied or really caught Conan, no matter what the situation, you must be prepared in advance.

……

Heiji Hattori only knows the location of the treasure, but he doesn't know what the treasure is.

He ran to the hall with Nishikawa and saw the old lady grabbing the oil painting and pushing it to the side.

The oil painting, which is four or five meters high, should have been extremely heavy.

But when Nishikawa pushed it, she didn't feel much resistance.

She was overjoyed, and became more and more excited—this would happen, of course, not because she was born with divine powers, but because there was a mechanism behind the painting.

The young man didn't lie to her, the treasure must be hidden here!

The painting is tilted at an angle, revealing a vertical upward passage at the back, and a ladder is nailed to the inner wall.

This kind of thing is very difficult to climb up, and it is also very challenging to be brave, but Nishikawa did not hesitate to burrow into the hole, and hummed and climbed up.

Shiraishi originally wanted to climb too, but when he probed in through the cave and looked up, he was worried that Nishikawa would be too excited, sweat too much, slip his palms, and fall and hit himself.

Moreover, this passage has not been used for many years, and there are several layers of cobwebs, and maybe when you climb to the top, there will be an extra layer of strange pendants such as "hanging veil and spider curtain" on your head.
