After contacting the secretary to explain the situation, the two of them discussed and decided to meet at the gate.

It just so happened that Conan also wanted to buy a bottle of ice cola to fill the loophole in the excuse he had made before.

I was standing by the gate drinking an iced drink and waiting. Soon, a capable woman in a suit and a ponytail came over and took out her cell phone as she walked.

"Here, here."

A moment later, his cell phone rang. Tang Ze waved and met the other party smoothly.

After a brief introduction, Terane Keiko agreed to Tang Ze's request to see where the paintings were stored.

"There are too many visitors. It will be faster if we go through the staff passage. Please follow me."

Terane Keiko explained, then walked around to the side of the art museum in her high heels, then swiped her card to enter the staff passage.

After entering the art museum, the two of them quickly arrived at a slightly shabby corridor under the guidance of Terane Keiko.

"This art gallery was originally the residence of a wealthy ancient family. Now it has been converted into an art gallery, and this passage is where the wealthy man stored his money."

As Terano Keiko spoke, she led the two of them to an iron gate. The two bodyguards standing at the door obviously knew each other. At Terano Keiko's signal, they quickly took out the key and opened the door.

There would still be a corridor when they entered, but Tang Ze felt that they seemed to be walking down the corridor, so he asked Terane Keiko directly.

"As expected of the renowned 'Ming Detective', it seems besides his trademark keen sense of smell, he's also astute in other areas."

Terane Keiko spoke words of praise, but her expression did not change much. She just glanced at Tang Ze and nodded in agreement, "That's right, since it's the treasure house of an ancient wealthy businessman, it's naturally not on the surface.

It is said that it was originally located in a master bedroom, but as time went on, the original bedroom was demolished and a new house was built. After changing hands and being transformed several times, it became a warehouse for the art gallery.

While explaining the history of the warehouse to Tang Ze and the others, Terane Keiko walked to the second door and entered the password. Then the heavy stone wall in front opened directly, revealing what was inside.

"Come in." Terane Keiko led the two into the storage room, where they could see many paintings displayed everywhere, and some picture frames piled up in the corner.

After following Keiko Terane's footsteps into the studio, Tang Ze had already activated his super sense of smell, but what entered his nasal cavity was not the residual smell left by a human but a chemical smell.

"Is there anything being sprayed here?" Tang Ze looked at Terane Keiko and asked.

"Sodium fluoride, an antifungal agent," Terane Keiko explained. "Because this is a basement, the room is a bit damp. To prevent mold from growing inside and damaging the paintings stored here, the entire room has been coated with sodium fluoride."

"That means your sense of smell is failing." Tang Ze sighed with a hint of regret: "I thought it would be easy to fix."

"Your reasoning ability is degenerating if you always rely on your sense of smell, Detective Tang Ze~" Conan joked when he saw Tang Ze being humiliated.

Because this case was just a missing painting and there was no murder, the two of them felt a little relaxed. After all, it was not a big deal.

For the Suzuki family, even if the painting was lost...it was nothing, not even a drop in the bucket.

So when Conan saw Tang Ze's "hack" fail, his mood instantly became a little happier.

"Well, there's no such thing as an all-powerful ability." Tang Ze glanced at Conan and said, "As for my reasoning, even if it's not as good as it used to be, I can still reach a level that some people can't reach. Your favorite Shinichi brother has no hope of surpassing me~"

Hearing the ridicule that was beyond words, Conan's face darkened and he was already jumping with rage inside, but because there were outsiders around, he could only endure it.

To outsiders, the conversation just now sounded like a child speaking up for his favorite brother, and then Tang Ze fought back. There was nothing suspicious about it.

Skipping this little episode in the middle, Tang Ze asked Terane Keiko to have the double-insured painting box where "Mirror Lake" was previously stored moved outside.

After reaching the corridor, Tang Ze once again used his super sense of smell to clearly smell the unique acrylic scent of the fake painting in the box.

"Okay, thank you." Tang Ze stood up and nodded to Terane Keiko. "Thank you for your cooperation. The investigation here is almost done."

"I understand." Terane Keiko nodded to show that she understood, and then asked the bodyguard behind her to put the box back into the warehouse.

However, this time when they left the storage room, the two followed Keiko Terane and took another path, which was the passage inside the art museum.

After arriving inside the art museum, Terane Keiko politely said "Excuse me" and left.

"How is it, did you find anything on the painting box?" Conan immediately came over and asked after Terane Keiko left.

"Some people are quite happy that my sense of smell is useless." Tang Ze looked at Conan and said jokingly, "Why are they so concerned about the information I get from my nose now?"

Conan's face darkened when he heard this and he said, "Are you going to tell me or not?"

Seeing that he had been amused for a while, Tang Ze said, "It can be basically confirmed that the fake was indeed placed in this double protective box.

After Ayako and I admired the paintings in the Suzuki family's warehouse, the boxes were sealed again, and the "steel seal" inside ensured that no one opened them before they were transported to the art museum.

"That means Mirror Lake can be confirmed to have been lost from the art museum."

Conan nodded and said, "When a painting arrives at the museum, it must be unpacked and inspected. Furthermore, it was only delivered yesterday, and it's gone missing today. I'm afraid someone on the inside must have planned this..."

The curator currently seems the most suspicious, after all, he is the one with the most legitimate access to the paintings."

"Indeed, but it's better to hold back for now." Tang Ze smiled and said, "How about we check for another clue?"

"You mean that?" Conan's eyes narrowed when he heard that, then he scratched his head and said, "But do you know anyone in this field? Without professionals, it would be difficult to gain anything."

"I didn't know him before, but I encountered a case some time ago and happened to get to know someone in this field."

Tang Ze said, pulling out a business card from his wallet and smiling, "After all, these two are well-known experts in their field. With their help, we should be able to find people in related fields to answer our questions."
