Compared to yesterday, in addition to a slight increase in visitors, there are also some more collections in the pavilion, which look old and expensive, and seem to have been donated by the owner of the real center.

Conan looked at it as he kept finding the bathroom where he met the man in black yesterday.

When he entered, he walked around the various chambers, and then retreated to the door, praying that no one else would come during this time.

Conan's luck seems to be good.

Soon, the only guest in the restroom washed his hands and left.

As soon as his back disappeared around the corner, Conan had already run into the utility room, and then he dragged out the "Cleaning" sign and propped it up in the doorway, and slipped into the door himself.

There was a lavender-scented freshener in the toilet, and there seemed to be a little smell of disinfectant mixed in with it.

Conan smelled it and felt bad. But it's coming...... He decided to finish it as planned.

He closed the door, leaned his back against it, looked up at the air in front of him, and remembered where the black cat was.

This was not too easy, although his attention was all on the other party at that time, after all, he was tilting his head and not paying much attention to the coordinates under his feet.

The bathroom is also luxuriously decorated, with countless small bricks with intricate patterns instead of regular white tiles on the floor.

Conan stared down at the unrecognizable patterns in the place, which were so large that he could only find a place as close as possible by his impression.

After a round trip, he put on a mask and gloves and turned out the lights in the toilet.

In this toilet, there is no direct window to the outside world, so although it is daytime, the room is pitch black when the lights are turned off.

Conan measured his pace, walked back to the position he had identified, and then crouched down and sprayed some luminol reagent from the Doctor on the ground.

Large blue-purple fluorescences quickly flashed on the ground.

As soon as Conan saw this posture, he lifted his cheeks and sighed in disappointment.

After a while, he pinched the bottle of reagents that still had a lot of reagents left, stretched out his arm and sprayed it to the side, and sure enough, it was the same situation.

The luminol reagent is buggy in its sensitivity for detecting blood stains, but this artifact is occasionally affected by other factors.

- The disinfectant that is occasionally used when cleaning the toilet is one of these "factors".

It is the same as blood, which will make the luminol reagent show that unique fluorescence, the difference is that the fluorescence caused by the two is not the same, and the fluorescence caused by blood stains will appear more slowly.

The Doctor can make almost anything, but it takes time for him to make things.

Conan originally thought that since the pavilion was about to close down, no one should be able to care about cleaning the bathroom so carefully in a day or two, but he didn't expect this "unexpected" thing to really happen.

Conan's purpose in coming to the pavilion this time was not to test DNA, and the doctor did not have this skill for the time being.

He was mainly curious, to see where the blood began to drip and where it ended.

I thought that the only thing he would be hindered by was the little hemoglobin mixed in the urine and wiped off by the mop around the urinal, but this time there was a more difficult full-coverage disinfectant.

Although the disinfectant will lose its concealment effect in a few days, now that there are more customers in the exhibition hall, the toilets in the future may have to be cleaned with disinfectant every day, and it is almost impossible for him to find the path of the bloodstains.

…… Is this also in the black cat's plan?

Conan looked at the ground reluctantly for a while, and finally returned to the door in the dark, turning the light back on.

……

Unable to get more useful clues from the medieval pavilion, Conan returned home in pity, a little depressed along the way.

However, before going up the stairs to the second floor, he looked at the café next to him and was suddenly stunned.

Anyway, the "suspect" is so close to him, or ...... Try to trick him?

Suddenly throwing out difficult questions and then observing the other person's reaction is also a good way to find the truth......

The more Conan thought about it, the more feasible it became, and after a few seconds, he finally made up his mind, retracted his foot on the steps, and felt back to the café door.

The lights were on, but for some reason, the light was dim, like a layer of fog.

Conan leaned on the crack of the door, trying to look in, as he thought of the right topic for the conversation - to make the other person let his guard down first, and then suddenly hit the point and catch the black cat off guard.

As he pondered, he vaguely saw two people behind the counter. But before he could see more, he leaned forward and accidentally pressed the door open.

Conan didn't take this little change seriously.

But at this moment, at the moment when he inhaled normally, an extremely strange smell suddenly rushed into his nose.

“…… Ahh Ahh ”

Conan covered his nose and jerked away, starting to sneeze uncontrollably, one after the other, unable to stop at all.

After more than ten seconds, his eyes were a little glazed, and Conan struggled to walk away from the store door with physiological tears in his eyes, and his mind was very confused - what the hell did that smell like!

After sneezing hard again, he took a deep reflexive breath, and was about to take the next one, when a hand suddenly reached out and pinched his nose.

Then the man quickly poured some cold potion into his mouth.

The unstoppable physiological reaction finally stopped, and Conan looked up dizzily to find two people standing in front of him, one seemed to be a new clerk in the store, her purple hair that only dyed the ends impressed Conan, and the other was even more familiar.

The two stood together, looking at him with a loving and apologetic look.

Then they took off the masks and goggles on their faces, and chatted to themselves: "The new product has not been successfully developed, is the pepper you bought flooded?" ”

"Whoever pours water into the chili pepper must be a problem with your recipe......" Shiraishi raised his hand to fan the wind around his mouth and nose, taking a big breath of fresh air.

Although I knew that they were discussing a new dish, I didn't know what it tasted like just now, and I thought it was a biological weapon...... Conan looked at the gentle, sweet-looking girl, and then at Shiraishi, who seemed to be accustomed to this situation. With a palpitation, he took two steps away from the door, and then he took a handkerchief from his pocket and wiped his face haggardly.

When Mao Lilan came home the night before, she had made a big effort to tell him about the café that was very close to their house, which was said to be about to open, saying that this would allow her to eat nutritionally balanced food when she was not at home, which was much more nutritious than their frozen food.

Originally, Conan was really excited, but now ......

Regardless of whether you can find out who the "black cat" is, at least there is something to gain today - absolutely not to enter this store, not to eat anything inside, absolutely!

Just thinking about it, there was a faint crackling sound of oil explosion in the store, and Bai Shiluo turned his head to look inside: "Have you turned off the fire?" ”

"Probably......" Butterfly Shinobi's voice gradually decreased, she blinked her eyes, and quickly changed the topic, "I'll go and throw away the baked things first, boss, you can come in when the smell is gone~"
