"I knew it." Looking at the embarrassed children behind him who were smiling with wide eyes, Gray Yuan sighed helplessly.

"Say," Gray Yuan hugged his shoulders and said in a light tone, "What are you guys secretly hiding here?" ”

"We ......" After struggling for a long time, Ayumi finally said, "We're all so worried about Conan and Kaede...... So ......"

"That's why I came here secretly, didn't you?" Gray Yuan stroked the tea hair on his forehead, his face was quite helpless, but there was a warm current surging in his heart.

This group of children...... Maybe it's what keeps them going!

"Whatever you want." Gray Yuan sighed in a pretentious gesture, "If I am killed, I will not be responsible!" With that, he continued to walk forward.

"Ahh Several children were taken aback, "What does Gray Yuan mean by this!! "Hurriedly chased after him.

What the alert Gray Plains didn't notice was that behind several children, another black shadow quietly emerged.

......

"Here it is!" After the children arrived in a room, Gray Yuan pushed the door and walked in.

"The room you've been in during the day?" Mitsuhiko said in surprise.

"Kojima-san, can you help me move that chair under the wall clock on the other side of the wall?" Glancing at the shouting Mitsuhiko with a little dissatisfaction, Gray Hara said in her cold voice to Motota on the side.

"Oh, good." Yuan Tai was stunned for a moment, and decisively did so.

Gray Hara himself moved a pile of books from the bookshelf and put them on a chair next to him.

"What the hell are you going to do? Gray Plains? Ayumi looked at Ashbara's movements with a puzzled expression.

"......" Gray Yuan didn't explain, but just stood on the chair with the stacked books, and reached out to pick up the hands of the clock.

"Ten o'clock...... Eleven...... Twelve...... A little...... Two points ......"

When the pointer was dialed to half past two, Gray suddenly felt the center of gravity in front of him suddenly unstable, and hurriedly supported it with his hand to avoid falling off the chair.

"It's ......!" Everyone stared dumbfounded at the revolving doors and dark tunnels in front of them.

"Just turn the hands of this dial and the secret passage will open." Gray Yuan climbed down from his chair, looked at the dark tunnel, and opened his mouth faintly.

"Alright, let's go!"

"Good!"

If Asaba was here, he would definitely find that the pointer he had played with was completely different from the time he dialed up tonight......

......

"Wait." Not long after entering the secret passage, Ashbara's flashlight suddenly stopped at one place.

Turning around, looking at the door that was pushed by him casually, Gray Yuan's eyes were firmly fixed on the crack in the door, and there was a rare trace of nervousness in his ice blue eyes.

He ...... Sure enough, it's here! Gray Yuan muttered a word, and no one but him could hear it.

As far as the eye can see, an entangled black and white velvet thread is impressive!

A scarf of a light feather!

"Hey, Grayplain, hurry up!" There was a shout from the front.

Ignoring the troubled thoughts, Gray Yuan forcibly suppressed the ominous premonition in his heart, carefully put away the ball of velvet thread, pursed his lips, and his gaze became firm again.

"Let's go!"

The Young Detectives walked down the stairs, Graybara's thoughts lingering on what they had just seen, and the light of the flashlight was a little careless.

"Huh?" Unexpectedly, it was this kind of careless strafing that made her see a dark red trace, and Gray Yuan's heart couldn't help but tighten.

"What is this?" The Junior Detective Corps also found this trace, and Mitsuhiko asked.

"Blood." The gray plain surface sank like water, gently twisting the bloodstains, "And, judging from the fact that the blood stains have dried up, it should have flowed not long ago." ”

"Wow! Gray Yuan-san, you are so amazing! Ayumi's eyes flashed with little stars, "You look like Conan now!" ”

"Now is not the time to talk about this!" There was no trace of happiness after being praised on Gray Yuan's cold face, "This bloodstain is very likely to be Conan's!" ”

"Ahh When they heard this, they were shocked and cried out in horror.

"And you'd better pray that this bloodstain is really Conan's!" Ash Yuan's next sentence made everyone stunned.

"Hey, Grayplain, how can you say that!" Yuan Tai, who had the hottest temper, said angrily.

"Fool!" Gray Yuan opened his mouth lightly and took out the ball of velvet from his pocket, "This is what I found at the door, on the scarf of the light feather." ”

"What!"

"This ball of velvet proves that he came here after eating." Gray Yuan's tone became serious, "Think about it, if this bloodstain is not Conan's, but Asa Feather, how dangerous our situation would be now!" ”

"......" Everyone thought of Asa Yu's combat power, and couldn't help but nod heavily.

And...... There was still a word in Gray Yuan's heart that he didn't say.

The one who can make him bleed is the other than that person...... Who else will there be? In Gray Yuan's mind, the blonde man with a cold smile came to her like a nightmare, and she clutched the dugong arrow in her arms tightly before slowly calming down.

It's weird, though...... Gray Yuan's heart was full of suspicion, except for the velvet at the door, there was no trace of him everywhere here, but this bloodstain was obviously new, this ...... What's going on?

"Look!" Mitsuhiko suddenly exclaimed.

Ashbara looked up and saw that the pillar of light from Mitsuhiko's watch-type flashlight shone right on a stone slab on the wall, revealing a line of handwriting on it.

"That man took my place, and he was trying to get the castle's treasure......" Reading this, looking at the half-written handwriting, Gray Yuan fell into deep thought.

"Supersed? Who replaced? Treasure? There were too many bits and pieces of clues mixed up in her mind, and she had vague ideas, but she couldn't find a clue.

"This, is this the one that Conan wrote?" Looking at the handwriting on the wall, Mitsuhiko asked worriedly.

"No," staring at the words, "judging by the words, it shouldn't be him, and besides, the nick is very old. Gray Yuan said coldly, "However, from the fact that the word treasure has not been engraved, one thing can be seen." That's it - he can't carve it anymore! ”

"Can't carve it?" Mitsuhiko, who was more sensitive, said in a trembling voice, "It's hard to ...... Don't! ”

"Yes!" Gray Yuan said coldly, "He's right here, and maybe he will die right here!" ”

Suddenly, the audience was silent!
