The lights in the hall were turned on!

"Didn't you drive it?" Qian Yu was surprised. "Do you mean..."

Now that the lights are on, it is clear that the person who turns on the light is intending to engage in some kind of public activity – and those who dare to do so are usually people who can be trusted.

Who could be here at this time? It's Conan or Ayumi indifferently.

With this in mind, Qian Yu opened the door.

Then he found out that his reasoning was wrong, for it was the old lady of the castle who appeared in the hall. And Mitsuhiko and the others were standing beside him.

"Qianyu, where did you go?" Ayumi said in surprise.

"Why are you here?" Qian Yu walked towards them in surprise - Gray Yuan Ai quickly walked in through the door.

"We couldn't be relieved just now, so we wanted to go to the room where Conan disappeared before and see if we could find the reason for Conan's disappearance," Mitsuhiko said. "Then we met the old lady upstairs."

"I just found out what happened," the old lady looked at Chiba with a peaceful gaze. "If it's a secret passage, I still know a little bit about it, and I might be able to help you find the missing little boy."

So saying, the old lady came to a pillar and pressed a stone brick in a very low position—this position was so low that no one would normally pay attention to it.

A floor tile suddenly lost its support on one side and tumbled down like a cellar door, revealing a tunnel.

"This is one of the entrances to the tunnel," said the old lady with a smile. "I'll take you in."

。。。

Qianyu's front shone with the light of a flashlight, leading Gray Yuan Ai and others to walk in front, while the old lady walked behind because of her inconvenient legs.

They came to the crossroads where Chiba had been before.

"The passage in the middle leads to the abandoned stone tower," said the old lady. "That little guy is probably hiding in that stone tower."

Just when the group heard this sentence and was ready to take the middle road...

"Wait a minute."

Qian Yu put away his mobile phone, and the people who were standing in the middle passage and the old lady who was still standing at the other end of the intersection saw it, and said lightly.

"Let's go to the left."

"Huh?" Ayumi was surprised.

"Huh?" The old lady looked at Qianyu. "Why?"

"Take this path." Qian Yu didn't explain, just looked at Gray Yuan.

"Hmm." Gray Yuan nodded and took the lead in changing to the left pathway.

"Uhhh After Ayumi and the others saw that Gray Yuan Ai had made a choice, they also changed to the left passage.

"Please, too." When several people walked into the left passage, Qian Yu said to the old lady.

“。。。” The old lady glanced at Qian Yu, and then slowly walked into the left passage.

In this way, the group walked into the left passage in an orderly manner.

After walking for about half a minute, Ayumi and the others in front of them exclaimed when they turned a corner. "Conan !!"

"Aren't you going to see your companion?" The old lady looked at Qian Yu behind her and asked.

"Makes sense." Chiba nodded and walked from behind the old lady to Ayumi.

A flaking stick fell out of the old lady's fluffy sleeve, and after being cleverly grasped by the old lady, it was whipped towards the back of Chiba's neck at an incredible speed - after the flaking stick was fully extended due to the high speed of the swing, the end section was very thin, and the power would be very terrifying when hitting the vital parts.

But Qianyu was like having eyes on his back, and his body suddenly became shorter, so that the end of the slinger quickly pumped a few centimeters above Qianyu's head.

“！！！” The old lady looked at Qian Yu who turned around in surprise.

"You did it, right?" Qian Yu held the Traceless Umbrella in one hand and said. "The disappearance of Conan and the Doctor."

"What?" At this time, Ayumi and Motota and the others had already poked their heads around the corner, only to realize that the situation was wrong.

"How did you find out?" The old lady tilted her head and looked at Qianyu.

"I started to suspect you when you climbed down the hall to the secret passage just now," Thousand Feathers shrugged. "Although your voice seems very old, you speak very coherently, no matter how you look at it, you look energetic, not to mention that when you climb down, your movements are very steady, not at all like you need to be in a wheelchair. As for why I'm sure it's you ... That's because of the Gray Plains. ”

"Huh? （？ The old lady and Ayumi and the others all looked at Gray Hara.

"Gray Yuan Ai just told me that he found footprints in the stone tower of a woman's shoe size - the pattern of this shoe is very peculiar, and it is not the type of maid's shoe in this castle at all. Just now, she went down the tunnel before you, and as you climbed down, she looked at the soles of your shoes and noticed that the footprints in the stone tower matched your shoes. ”

"Then how did you find out that this kid and a few of them are here?" The old lady nodded slightly in approval.

"My nose is smarter." Chiba shrugged - he couldn't say that it was because his auxiliary unit had helped him resolve the abnormal smell of blood in the left passage, right?

"Forget it, none of that matters." The old lady took off her robe, revealing the black tights underneath. "The point is to keep you all here!"

"Oh my God..." The corners of Chiha's mouth twitched. "Well, can you ask what you did before you disguised yourself as an old lady?"

"That's the question..." The old lady turned the stick in her hand twice. "I used to be the personal bodyguard and head maid of the eldest lord and the old lady. If you go back in time, I used to be a killer. ”

"So..." The old lady arched slightly. "There is no point in your resistance, your only end is to die here."

"Cut!" Qian Yu frowned, and retreated as the old lady moved forward.

The old lady took a step forward, and the flicker instantly slashed down, directly smashing Qian Yu, who had hurriedly completed the block with the traceless umbrella, to his knees on the ground.

The old lady raised her stick, and then slashed it again. But this time, Qian Yu had already reacted, and instead of making a hard connection like before, he turned the split stick at a small angle through the traceless umbrella and directed it to the side. After that, Qian Yu sent the traceless umbrella forward, and stabbed it directly in the stomach of the old lady who couldn't control her strength and staggered forward because the flicker was pushed aside.

Although the old lady's strength is very large, Qian Yu has received corresponding training when she was conducting combat training in the organization, and knows how to fight against opponents who are much stronger than her own through unloading and weak points.

However, just after Qian Yu had just hit the old lady, the old lady immediately pulled the throwing stick that had been pulled to the ground horizontally as if she had not been hit at all, and hit Qian Yu's leg.

"Ahh With a scream, Chiba fell to the ground, and the Traceless Umbrella slid out of her hand.

"This pain... Looking at Qianyu who was curled up because of the pain, the old lady gritted her teeth and said, "I used to suffer too much, it's nothing... Right now... ”

The old lady held her stomach with one hand, and walked towards Qianyu who fell to the ground with a throwing stick in the other.

Her movements froze.

Gray Yuan Wai didn't know when he came to her side through the darkness and against the corner of the wall, and stabbed the finger tiger that Qianyu gave him into the back of the old lady.
