Traveling through Conan: Buying Poirot Cafe at the beginning

Time slipped away bit by bit, and it came to ten o'clock in the evening.

The melon-eating crowd that originally gathered around the aquarium also went back to their homes.

Yang Ming and Conan were waiting anxiously outside. Conan was holding a blueprint with a code. He understood the first half of the code, but he still couldn't understand the second half of it.

At this time, a police officer came outside the aquarium and reported to Memu.

"Report to Officer Megure, we have searched the aquarium and found nothing unusual."

"What did you say?" Mu Mu raised his eyebrows and looked at Yang Ming in confusion.

Is it possible that the information about the bomb is false? Mumu would rather believe in the accuracy of the news than think about the incompetence of his subordinates.

"In this case, I think it's better for the two of us to go in and look for it?"

Yang Ming said softly that he had already seen that Conan could not wait any longer, so he asked Officer Memu to enter the aquarium.

"That's all it can do. After all, Mr. Yang Ming is also a bomb disposal expert. It was Mr. Yang Ming who found and defused the last bomb."

Officer Mumu pinched his chin and recalled that he did not refute Yang Ming because he still wanted to get inside.

Yang Ming and Conan entered the aquarium, and police officers kept going back and forth in the aquarium.

The two entered from the lobby. There were some fish tanks on the first floor of the aquarium, which contained some native fish.

Other than that, there was no other place on the first floor where a bomb could be hidden. The two didn't stay long and arrived on the second floor.

On the second floor of the aquarium is a simple ecological circle. There are various fish in the huge glass tank, just like a simple lake.

But this lake is sealed, which is also one of the biggest attractions of the Rice Flower Aquarium.

Because the oxygen produced by the corals inside supplies the organisms in the water, and the carbon dioxide exhaled by the organisms feeds the corals.

Yang Ming stared closely at the stones and corals in the ecological circle, but there was nothing there after looking at them for a long time.

The two of them had no choice but to go to the third floor. The layout on the third floor was similar to that on the first floor, but the fish tank was much larger, and most of the fish they raised were foreign fish, many of which they had never seen before.

"How about Conan, did you find anything suspicious?"

Yang Ming stood on the third floor of the aquarium and looked down.

The center of the aquarium is free, and you can see the police officers on the first floor from the fence.

"No, I have actually been thinking about the second half of the riddle. Beautiful flying fish will come to this earth with a roar. What does it mean?"

Conan sighed. It was almost eleven o'clock, but they hadn't even found the bomb yet.

The roar is easy to understand and refers to the sound produced by bomb explosions. But what exactly do flying fish and earth refer to?

"Let's go downstairs and see if the police find anything."

Yang Ming also sighed and thought: You are not good at this. A simple riddle stumped you.

"Yang Ming, have you discovered anything?" Mu Mu saw Yang Ming walking out of the elevator and asked.

Yang Ming shook his head and looked around, doubtful in his heart. There was something suspicious about the ecological circle on the second floor of the aquarium.

"Hey, Conan, let me ask you. How often do you think the water used by these marine creatures needs to be changed?"

Conan was stunned and looked up at Yang Ming.

"Probably once a week. Why do you ask?"

Yang Ming pinched his chin. He was a little suspicious now and found the director of the aquarium.

The curator is wearing a gray suit, has a slim build, and looks to be in his forties.

"Are you the director of the aquarium?"

"Yes, how can I help you?"

The curator was very polite, Yang Ming asked with a smile:

"Excuse me, how do you change the water source for the ecological group on the second floor?"

The curator was obviously taken aback. He didn't expect Yang Ming to ask this question.

"Well, actually this is not a secret. Because the ecological circle on the second floor is airtight, we cannot pump out all the water at once. This will cause an imbalance between the air pressure inside and outside, which may cause the glass to burst. .”

"We use a water storage and pumping mode. There are two water inlets at the upper end of the ecosphere and two water outlets at the lower end. In this way, water is added and water is discharged at the same time, so that the water source can be replaced and the ecosphere can be improved. water quality.”

Listening to the curator's words, Yang Ming also had some guesses, but Conan didn't understand the reason why Yang Ming asked.

Yang Ming ran into the elevator again, this time dragging the curator with him, and Conan followed closely behind.

"No, what are you going to do? The bomb is going to explode in half an hour. Shouldn't we run for our lives?"

The curator was a little anxious. Compared to the aquarium, he felt it was better to save his life first.

"Brother Yang Ming, have you figured out something?"

Conan pulled Yang Ming's clothes, and the elevator reached the second floor.

"Ang, I already know where the bomb is hidden."

The three of them came to the second floor and looked at the huge glass in front of them. There were various creatures inside.

"Excuse me, curator, when will the next water source be changed?"

The curator pondered for a moment and replied: "If I remember correctly, it should be twelve o'clock tonight. This is our fixed time every week."

Conan seemed to be struck by lightning and spoke with difficulty: "Is it possible that the bomb is hidden in the two water inlets?"

It seems like this. What Pramya uses is a liquid bomb. As long as different liquids are put into the two water pipes in advance.

When the system starts up, the normal water will be discharged, and the liquid bomb will flow in along the water filling port. When the two meet, a violent explosion will occur.

"So that's it, curator! Hurry up and ask the staff to turn off the water exchange system! The bomb is hidden in here!"

"What? Turn off the water exchange system? It cannot be turned off now because it is not controlled by humans. When we built this ecosystem, we designed the water exchange system to work according to cycles. This way we don't have to worry about it. Forgot to change the water.”

"The person who designed this building was killed at Mihua Station three days ago. The murderer has not been found yet."

Yang Ming and Conan looked at each other, not expecting this situation.

Because the water exchange system cannot be turned off, the bomb in front of you will become an unsolvable bomb.

The two of them could only watch helplessly as the bomb exploded.
