After a simple meal, Tang Ze called Ayako and told her that he had to go out for an urgent matter, and asked her to go home for dinner. Then he went to Dr. Agasa wearing a disguise mask.

Tang Ze was very much in favor of disguising himself and going with Conan to investigate this matter, and he would even take the initiative to do so even if Conan didn't say it.

Although there will be no risks in this investigation and the ones being investigated are friendly forces, as he continues to intervene in the plot line, Tang Ze doesn't care about how this gradually out-of-control plot will unfold.

The only thing he could be sure of now was that the Black Organization must be frantically searching for Rena Mizunashi and also frantically searching for any clues about the enemy.

At this time, he cannot appear in the sight of the Black Organization, even if there is only a slight possibility.

In addition, there are other benefits to pretending to be an old man. After all, the previous store manager has passed away, and as a friend, he is older and can more easily gain the other party's trust.

As for the clothing, Tang Ze chose a more old-fashioned suit, which matched the charitable look of the old man in the mask. At first glance, he looked the type that was easier to believe.

"You're pretty fast."

Shortly after the call, Conan ran out of Dr. Agasa's house and got into the car directly: "I thought you would be away for a while, but I didn't expect you to have even prepared your disguise right away."

"After all, it's a serious matter." Tang Ze smiled and said, "You have to pay attention to it."

"You are the one who cooked dinner before coming here, and you have the right to say this." Conan complained speechlessly.

"The timing is just right now. The time before was dinner time, and they might still be eating when we went there, which would have been inappropriate."

Tang Ze explained and looked at Conan and said, "Then give me the phone number, I will contact him."

"This is a phone." Conan showed the phone screen to Tang Ze and asked with some concern: "Is everything okay?"

"What do you think is wrong?"

An old voice sounded in the car. Conan was stunned for a moment before praising, "It's amazing! This voice changing is probably comparable to Kaito Kidd, right?"

"Not as good as him." Tang Ze shook his head and said, "Right now, I'm most proficient in men's voices. Old men have only practiced this one fixed voice line. As for children's voices, it's only you and Huiyuan's."

"Why are you imitating our voices?" Conan asked in surprise.

"Just in case, I'll cover you."

Tang Ze smiled and said, “Especially yours, I can also help you to prevaricate Xiaolan over the phone when you need it.

After all, your personality makes you like to rush into danger. In order to avoid trouble caused by not being able to contact you, I practiced a little.

By the way, I can also sing your original voice."

"Then I really appreciate your thoughtfulness."

Although he knew that Tang Ze was doing this for his own good, Conan couldn't help but droop his eyes when he heard his original voice coming out of the other person's mouth.

After all, the fact that the other party imitated his voice made him very unhappy.

But...I can't refute it...

Although he was unhappy, what Tang Ze said was true. At least he felt more at ease knowing that he had such a backup plan.

So even though Conan felt a little aggrieved, he still thanked Tang Ze.

Tang Ze waved his hand to indicate that you're welcome, and then dialed the number provided by Conan.

Soon the call was connected and a young man's voice was heard.

After introducing himself using the made-up name, Tang Ze began to talk about the purpose of this visit: "It is like this, I was asked by your grandfather before he died to pass on a very important item to a customer who used to visit the store frequently.

I have a rough idea of ​​what that person looks like, but because the item is quite valuable, I still want to confirm it again."

"Ah~ Are you talking about the guest who often comes with his son?"

The young man's question came from the phone.

"It must be him."

After hearing the words coming from the phone, Tang Ze and Conan looked at each other, and then asked in different voices: "I remember he was a man who didn't like to talk much. I wonder if you have his name and address?"

"Ah, that must be him."

After hearing Tang Ze's words, the man on the phone seemed to trust him more, but unfortunately the other party said that he did not know the other party's specific information and said that he had only seen him two or three times.

"Do you know what characteristics that man has?" Tang Ze continued to ask in his old voice, "Because I can think of two or three people who meet the target."

"Even if you suddenly ask me this, I can't remember it right now..."

The man seemed a little distressed, but then he changed the subject and said, "If it's convenient, would you like to come and see this person's photo?"

Tang Ze was not surprised to hear the man's words, but when he looked at Conan, he saw a strong desire to explore in his eyes.

"You have a photo of him? But I heard that he doesn't like having his photo taken."

Tang Ze signaled Conan to calm down, and smiled and pointed out another characteristic of the other party, continuing to increase his credibility.

"That's right."

As expected, after hearing Tang Ze's words, the other party's tone became more relaxed: "But this photo was taken by chance.

I think his son accidentally pressed the shutter button while playing with my camera and took the photo."

"I wonder if it's convenient for you now?" Tang Ze said calmly, "I want to go see that photo now."
