Chapter 688 is called a grand fireworks display.

Conan smiled upon receiving Qianzhu's affirmation.

He was excited not because of the program itself, but because of its functionality.

If used properly, it can definitely play a huge role.

"You can study the specific information about this program on your own first, and then ask Qingyao for details when he comes back in a few days."

Before he left, Qianzhu said one more thing to him.

"Okay! I understand."

Conan put the program back in the box and put it away, not intending to use it immediately.

After all, he trusted Qianzhu, not Liu Qingyao.

Although he didn't know why Liu Qingyao created this program, he didn't believe that the other party knew that he was Shinichi Kudo.

Moreover, the suspicion surrounding "L's" identity has not been completely ruled out.

If he is indeed a member of the church, then he might be trying to obtain some information through Qianzhu.

However, he always felt that the other party seemed more like they needed to obtain information about Qianzhu or something similar...

Under the bright moonlight, a white figure stood on the rooftop. A white cloak embroidered with gold patterns fluttered slightly in the wind, and cold eyes beneath the hood moved slightly with Conan's movements.

Noticing that someone was looking at him, Conan suddenly turned around and glanced around, but he didn't find anything.

A look of seriousness flashed in Conan's eyes, then he continued walking away.

...

Mihana General Hospital.

Behringer rested his chin on his hand, watching the Junior Detectives Group that had come here.

"Brother Behringer, are you all healed now?"

Ayumi stood by the bed and asked with concern.

Behrfinger smiled, narrowing his eyes. "Don't worry, don't worry, I'm almost fully recovered."

"Even so, you need to take good care of yourself." Ai Haibara stood beside him with her hands on her hips, tilting her head slightly to gaze into his eyes.

"Ai, you're so strict!" Behringer said, looking aggrieved as she fiddled with her fingers.

Ai Haibara gave him a half-moon glare.

Behringer chuckled at her, then turned to look at Conan standing by the window, a malicious smile spreading across his face.

He moved over there and then reached out to pull Conan towards him.

Conan was suddenly pulled back, and when he turned to look at Behringer, he saw his mischievous smile and saw him staring at him with his eyelids down. "What are you doing?"

Behringer's smile widened, and she leaned close to his ear and whispered, "I heard about it—you confessed to Ran!"

Conan: !!!

"How did you know?!" he exclaimed in alarm, his face flushed and his expression panicked.

The very next second after he shouted it out, he thought of Kawasaki Maru, whom he had met in Chongqing...

Conan: "..." So he still saw it!?

Behrfinger covered his mouth and chuckled, looking on with anticipation. He bent down and whispered to him, "Did Xiaolan agree?"

Conan glared at him, looking embarrassed and annoyed. "Idiot! Don't gossip about things like that!"

Behrfinger blinked, then suddenly turned her head and whimpered, "You're bullying me..."

On the other side, Ayumi and the others blinked in confusion, completely baffled as to what they were whispering about.

"She definitely hasn't given you an answer yet, right?" After a few whimpers, Behringer turned back to continue gossiping.

"Ah, um..." Conan blushed, his gaze unconsciously shifting to other places.

Seeing this, Behffiner spread his hands, shook his head, and sighed, "What a pity."

Conan: "Hey, hey..."

Seeing his embarrassed expression, Behringer laughed as if he had succeeded in his prank.

Mitsuhiko blinked, sat down, and handed a game console to Behefinger. "Behefinger, let's play some games together. Haibara said last time that you were bored here."

Upon hearing this, Behringer's eyes lit up, and she happily took the game console, exclaiming, "Great! Great!"

Looking at the childlike Behringer, Ai Haibara crossed her arms, sighed helplessly, and then a smile curved her lips.

The Junior Detectives spent a long time playing video games with Behringer in the hospital room, and it was already getting close to dusk outside the window.

After finally finishing the game, Behringer stretched, but then stiffened again because he aggravated his wound.

Behrfinger: "..."

He handed the game console back to Mitsuhiko, clapped his hands, and said happily, "Thank you for coming to visit me, otherwise I would have been so bored!"

"You're welcome. Well then, Brother Behefinger, you should get some rest. We're going back now."

Mitsuhiko put away the game console, and after saying goodbye to everyone, he left the hospital.

As they walked out of the hospital, a paper airplane suddenly bumped into Ai Haibara's forehead.

She caught the paper airplane and touched her forehead where it had been touched.

"Hey, there seem to be words on this!"

Ayumi noticed some text peeking out from the folds above, pointed at the spot, and exclaimed in surprise.

Ai Haibara also noticed it, so she unfolded the paper airplane and saw several lines of text on it.

[Things from Xishui float carefree in the air.]

The large cage hinders movement.

But the massive fireworks display was already prepared.

Even if the night does not reach,

It doesn't detract from the spectacular fireworks.

Looking at the above sentences, Ayumi and the others were completely dumbfounded.

"Is this... a code?"

"Probably." Conan took the paper and looked at it.

"Does 'things familiar with water' refer to creatures that live in water?" Ayumi pointed to the first sentence. "But what fish floats around in the sky?"

Mitsuhiko thought for a moment, then suddenly had a flash of inspiration, "I know! It's flying fish, right? Flying fish can also leap out of the water and glide short distances in the air."

"That makes sense, but what is a giant cage?" Genta scratched his head with a blank expression.

"What they're talking about is probably an aquarium, right? After all, aquariums are designed to be very tall for humans, so it's normal to compare them to being in the air," Ai Haibara guessed casually, arms crossed.

"That's true, and aquariums really do feel like cages for those fish..."

"Does that mean the aquarium is planning to celebrate something and therefore plans to set off fireworks?"

"So aquariums set off fireworks for celebrations?"

The three boys huddled together, chattering away.

Conan turned the paper over and over, but still couldn't figure out whether the contents were foreshadowing anything.

"Speaking of which, could the fireworks refer to an explosion?"

As they were chatting, Ayumi suddenly said something.

Conan, who was about to casually stuff the note into his pocket, paused, turned to look at her, and asked, "Why?"

Ayumi turned around, tapping her chin with her fingertip as she recalled, "Because I watched an anime when I was bored the other day, and the villain in it referred to explosions as grand fireworks."
