Chapter 349 is just a number.

He rubbed his head where he'd been hit and turned around to see Qianzhu smiling at him. "I knew it was you who followed me."

Conan chuckled, oblivious to his embarrassment at being caught, and said, "I was just a little worried about you."

Qianzhu smiled, turned around and walked onto the rooftop.

Conan quickly followed, looked around at the deserted rooftop, and tilted his head in confusion to look at the boy sitting on the stone bench. "Qianzhu, what are you doing here?"

"Just came here to get some fresh air."

With a faint smile on her face, Qianzhu glanced at the sunset fragmented by the iron fence, took out her phone from her pocket, switched to the dial pad, and slowly typed in a number.

It's not a phone number, just a string of numbers.

1155665-

4433221-

5544332-

5544332.

Conan, who sat down next to him, glanced at it and a question mark appeared on his forehead. "What's this?"

Qianzhu looked at him and chuckled without saying a word. Then she deleted the number and, while humming a melody, typed the number back in, word by word.

The gentle humming was carried into the air by the breeze and quickly dissipated.

The warm twilight bathed the boy, his eyes the same color as the sunset, gentle and enduring.

After humming that short melody, Qianzhu deleted the number again, looked at Conan with a smile, and said, "It's Twinkle Twinkle Little Star."

"This is the first piece of music I've learned."

He said softly.

My fingertips skillfully tapped the phone buttons once again.

Seeing Conan's hesitant expression, Chizu couldn't help but chuckle. She gently poked his head and said, "Just ask whatever you want to ask."

Conan hesitated for a moment, then asked, "Is there any significance to this?"

"Hmm?" Qianzhu looked at him for a few seconds and shook her head. "It doesn't mean anything. It just happens occasionally, like now."

After saying that, he smiled and patted Conan's head, then stood up. "Alright, let's go back."

Conan nodded, stood up, and went downstairs with him to Behringer's ward.

When they returned, the Kawasaki brothers had already left.

After glancing at them, Behfinger turned to Xiaolan and the others with a smile and said, "Alright, you guys go back. I'll be perfectly fine on my own at the hospital."

It was probably agreed upon while the two of them were away. Xiaolan nodded and told Beihefeng to rest well before leaving the hospital with Qianzhu and the others.

Sitting in the car, Qianzhu seemed to have a premonition and touched 01, saying to it in her mind, "It seems that I just left the hospital today as a visitor, and now I have to go back in as a patient."

01 Shocked: [Huh!? Why!? Why!?]

Qianzhu gently curved the corners of her lips, "Because I've been using too much magic lately."

01 silently clenched his fist, the thought of slaying the world's consciousness rising in his mind for the nth time.

Just as Qianzhu had said, he hadn't been away from the hospital for more than a few minutes when he experienced severe pain in his heart and stomach, which made his face turn pale.

Ai Haibara and Conan, who were sitting next to her, both noticed that something was wrong with him at the same time.

"Brother Qianzhu!" Conan helped Qianzhu up, who couldn't help but bend over, and then leaned over to the front seat and shouted to Kogoro Mouri, who was driving, "Uncle, turn around and go to the hospital!"
