Conan saw a small mold stain on the tissue and began to think.

Mold stain?

He began to look around the room and soon spotted a mess lying near the door.

Conan ran over on his short legs to take a look, took a photo with his phone, and then looked at it again.

This mold stain seems to have gotten on the sole of my shoe, and it just happened to get on when I walked over.

Conan looked up thoughtfully, but did not find any similar mold stains anywhere else.

It can't be that this is the only place that's affected, right?

Or... cleaned?

Conan and his friends are busy solving the case, but Lu Qi's place is deserted and lonely, with a very bad atmosphere.

On the surface, Kudo was leaning against the wall with his arms folded, looking indifferent, but in fact, his core, Lu Qi, was staring at the ground in a daze, with a look of despair on his face.

It's so funny! No matter who comes to the world of mystery anime, they will feel very disappointed when they are about to watch the plot with gusto, but the whole story is revealed as soon as they look up!

What's more, he didn't have the desire to show off his skills, and it was estimated that Kuro Kudo didn't have the desire either - he didn't feel the impulse in his body - so after being thoroughly exposed, he just lay down.

What case? Why don't I know?

Watching a group of children jumping up and down looking for clues and discussing the case enthusiastically, Lu Qi had a strange illusion that they were exploiting child labor.

Lu Qi: Numb.

Seeing Ayumi and her group running towards him excitedly after finding a new clue, Kudo's eyes uncontrollably swept over Toru Amuro and Subaru Okiya who were working hard to solve the case on the other side.

If I remember correctly, these two can be called the guardians of these children.

...Oh, and Dr. Agasa.

So why is he the one taking care of the kids all the time?!

"Brother Ichi!" Mitsuhiko was the first to arrive this time. He stopped in front of Kudo, panting a little. "We followed your instructions and successfully got Mr. Yamamoto's manuscript."

Ayumi excitedly shook the thick stack of papers in her hand.

"Very impressive," Kudo squatted down and rubbed Mitsuhiko's head, "Now let me tell you a little common sense."

"Thin people tend to write with more force, which is what we call strong pen pressure."

The three elementary school students followed the instructions and looked at Yamamoto Kazuhiro's manuscript, and exclaimed in surprise.

"Yeah, I used a lot of force!" "Yeah, there will be a protruding outline behind the paper." "The pencil broke many times, too."

"! Brother Yi is so awesome!"

"No, if you pay attention to collecting some useful knowledge, you will know it."

Facing the admiring gazes of the group of children, Kudo answered with a smile.

"So keep up the good work, little detectives." Kudo made a cheering gesture as if jokingly.

"We will try our best!" the children were full of fighting spirit.

"But the words on the suicide note I just saw seem different - it looks like the writing is very light, and some of the words are hard to read." Guangyan put his hand on his chin as if thinking, "Why is that?"

"Think about it carefully, okay?" Kudo looked at them calmly, "You should learn to think independently."

"Ah... is it because Uncle Yamamoto was very sleepy when he was writing?" Genta made a sleepy expression, "If I were very sleepy, I wouldn't have much energy to write."

Before Kudo could say anything, Ayumi shook her head and said, "That's impossible, Genta. It would be hard to write so neatly if you were so sleepy, right?"
