Who is he?

Qian Yu quickly turned around and looked at the end of the stairs - the light of the flashlight under his arm also shone there.

There is no one, as if everything is just an illusion.

Wait a minute, this is a closed space. If the entrance to other secret passages is opened, you may hear the wrong direction in this place...

Anyway, someone came in...and he should be the murderer...

Qianyu turned his head and started exploring the entire secret passage again.

When Qianyu's footsteps gradually became fainter, a man climbed up from the platform at the entrance of the secret passage - he had been lying on this platform that became a blind spot for Qianyu's vision before so that he could not be discovered.

...

Hui Yuan Ai held a small flashlight and stood in front of the door of the room where the secret passage was located. He tried to open the door, but found that the door was locked. "..."

Something's wrong... If this place is still locked, how did Qianyu get in?

Could it be that after Qian Yu entered, someone else entered?

So...wait a minute, I remember that a manservant died while exploring the abandoned stone tower? Could it be that...

After Hui Yuan Ai thought for a moment, he walked downstairs.

Behind her, a person secretly watched her leaving figure and followed her.

Outside the abandoned stone tower, Hui Yuan Ai looked at the lock at the door of the stone tower - the lock was opened.

"..." Haiyuan Ai hesitated - in theory, the lock should be locked. If the lock is opened, it means someone broke in from here...

He's a prisoner...Qianyu doesn't have the key...

Huihara Ai was about to leave, but then he remembered something.

Why did the murderer come in?

Qian Yu chased the murderer, but the murderer escaped? Impossible. If that was the case, Qian Yu must have come out to find them.

Then there is only one possibility - the murderer opened the lock here for some purpose...

Excuse me, what did the murderer do?

Perhaps, Conan is hidden here by the murderer...

So, the murderer shouldn't be here? The murderer should be fighting Qian Yu now...

Hui Yuan Ai felt relieved and walked into the stone tower with a flashlight.

There was no furniture in the stone tower - it had apparently been abandoned after the fire cleared the site.

But obviously it was not completely abandoned.

Hui Yuan Ai looked at the footprints on the ground and identified them.

These were the footprints left by a pair of small shoes, and they did not appear to belong to a tall, strong man.

Wait a minute...the only things in this villa that don't fall into this category are...

Hui Yuan Ai frowned. "How is this possible?"

That old woman?

No...others in this castle also have this condition...

The previous burning of the stone tower was probably also the work of the murderer, but that fire burned almost all the old servants to death, so how could the new servants have the motive to do this?

And those who escaped the fire and lived in that castle long enough...

Only the old lady...

"Why are you here?" At this moment, a man's voice appeared behind Haihara Ai.

"!!!" Hui Yuan Ai turned around in surprise, only to see the bald gardener holding a stick and questioning her with a ferocious expression.

Before she had time to think too much, Haihara Ai immediately ran up the stairs in front of her.

"Don't run!" the gardener yelled, grabbing a stick and chasing after Haiyuan Ai.

There was a door at the end of the stairs. Haiyuan Ai immediately ran in and locked the door latch. Fortunately, it was a latch instead of a door lock. As long as it was locked from the inside, it would not be possible to open it from the outside.

As soon as she locked the door latch, the gardener slammed into the door, making Hui Yuan Ai, who had just locked the door, take a step back in fright.

Collision, collision repeatedly. As the gardener kept hitting the door, Haiyuan Ai could even see that the door latch was being knocked loose by the gardener.

"Huiyuan?" At this moment, a surprised voice came from beside Huiyuan Ai.

...

After the secret passage descended to the level of the underground level, Qianyu discovered that the secret passage had entered a horizontal state.

Are you going out of the castle? From the direction, it seems to be heading towards the abandoned stone tower?

As they walked, there was a crossroads in front of them. There were three roads with no end in sight. Qianyu recalled the direction of the abandoned stone tower and chose the middle road - that road should lead directly to the abandoned stone tower.

A minute later, Qianyu discovered that the passage in front of him was blocked by a stone wall - the stone wall was inlaid with iron ring-shaped handrails, and there was a one-meter-square passage directly above it, which was obviously designed to be climbed up through the handrails.

Qianyu climbed up from the railing and saw a small space above, and there was a button on the side stone wall that was obviously a switch.

Qianyu pressed the button, and with a sound, the stone wall in front began to rotate, revealing the scene behind the stone wall.

Behind the stone wall is a toilet, and the door of the toilet on the opposite side is wide open - outside the toilet door is Haiyuan Ai with a horrified look.

"Haiyuan?" Qianyu asked in surprise.

"!?" Haiyuan Ai was shocked when he heard Qian Yu's voice.

"Why are you here?" Qianyu asked. "Didn't I tell you to hide?"

"Don't talk about this yet..." Haihara Ai was about to speak, but the door latch, which was being constantly hit by the gardener, looked like it would collapse at any time. "The gardener outside the door is about to break in!"

"..." Qianyu immediately raised the traceless umbrella and expanded it to a mode capable of long-range shooting. "Leave it to me."

At this moment, the door latch was knocked open and the gardener rushed in.

The nozzle of the traceless umbrella was pointed at the gardener, and a crossbow arrow shot out of the crossbow's mouth and pierced the gardener's neck.

"Ahhh!" The gardener screamed and fell to the ground, trying to pull out the crossbow bolt from his body, but after pulling out the crossbow bolt, he lay on the ground in pain, rolling around desperately and wailing loudly.

Qianyu stepped forward and hit the gardener's back with the traceless umbrella like an iron rod - for reasons that Qianyu himself could not explain clearly, he did not want to kill anyone in front of Hui Yuan Ai, so he chose to temporarily incapacitate him in this way.

Removed the Gardener's resistance.

Later, Qian Yu took Hui Yuan Ai and escaped from the stone tower.

...

"Why did you come out?" Qianyu asked again while walking on the stone road outside the stone tower.

"..." Haiyuan Ai hesitated for a moment. "Because...because I felt it was a shame to abandon a friend like this, so I came back to you...well, because you are a friend."

"Okay," Qianyu shrugged. "I remember you were hiding here just now..."

Looking at the deserted grass, Qian Yu and Haiyuan Ai's expressions changed.

"Where are they?" Qianyu asked Haiyuan Ai.

"I don't know..." Hui Yuarai shook his head and murmured. "I really don't know... wait a minute..."

Haihara Ai pointed to the hall of the castle.
