After leaving the old woman's house, the three little ones no longer had any worries. After all, the old woman had answered Conan's questions very clearly.

I wanted to live in this kind of house when I was young, and my only son also lives nearby.

After all, the three little ones are still children, so they easily believed what the other party said. After all, these reasons are really impeccable.

But Conan still had some doubts, and even at night, he kept thinking about the visit he had made during the day.

He vaguely felt that something was wrong, but he couldn't tell where.

After careful recollection, Conan suddenly remembered the way the old man supported himself on the ground when he stood up in the morning.

"This? I feel something is wrong... But anyone who's older would do the same..."

Conan vaguely felt that something was wrong, but he didn't know where it was. "Also, why did the old woman have such a disgusted expression at that time..."

When Conan was talking, he was interrupted by Xiaolan, "Hey! I have to go to a religious ceremony with my father tomorrow night. Please look after the house!"

"Ah, is that so!" Conan scratched his head and smiled awkwardly: "Sorry, sorry."

"Really, don't let your imagination run wild while eating!" Mouri Kogoro punched Conan, which caused Xiaolan to scold him.

.......

The next afternoon, as soon as school was over, Conan immediately ran out of the school gate.

Soon he arrived outside the school gate, looked around and saw a black car parked on the side of the road, then he opened the door and got in.

"Thank you for your hard work, Detective Tang Ze." Conan took off his schoolbag, "Thank you for coming here."

"It's okay. Huibara said before that someone was following you. Do you think it was them two?" Tang Ze said while driving.

"It's hard to say..." Conan stroked his chin and pondered: "But that day I did feel that someone was spying on me..."

Hearing this, Tang Ze frowned, somewhat confused.

After Haibara, the "little spy" planted next to Conan, informed Tang Ze, he became more vigilant.

After all, this is what happened to Conan. He said he felt someone was watching him from behind, so it must be someone watching him from behind. There is no possibility of an illusion.

That night, Tang Ze called Conan and asked him in detail about his recent movements.

Originally, he wanted to judge based on the "Law of Science" to see if the other party had triggered any elements of a case and was ready to find a murder case.

But what he didn't expect was that Conan really didn't seem to cause any trouble this time.

He didn't visit anyone else's house, nor did he meet anyone suspicious and investigate, and the three little ones around him didn't encounter any problems either.

Everyone just goes to school, goes home after school, and goes back home as normal.

If I have to say something, I went to see the new house that day, and then that was it.

But this didn't involve any close contact with anyone, which gave Tang Ze a headache at the time.

However, Conan contacted him again soon and said that an elderly couple had moved into the house he had seen before. He felt that there was something wrong with the two of them, but he couldn't tell what was wrong. He hoped that Tang Ze could investigate with him.

Tang Ze naturally agreed to this. After all, Conan came to him for help on his own initiative, so he had to take it seriously. Maybe he could stop the case and get a reward.

As for Conan's suspicion that he was a member of the Black Organization, Tang Ze was not worried.

If Tang Ze might have forgotten other cases or characters, then he would definitely have no impression of the main plot and the people in the Black Organization.

And he had no memory of the Black Organization disguising itself as an elderly couple.

In other words, this does not involve the main plot.

Of course, necessary preparations must be made, and Tang Ze also needs to be prepared for any eventuality in case his appearance causes changes outside the plot.

So Tang Ze rented a car in disguise to investigate and track the situation, so as to avoid any unexpected situations that might catch him off guard.

They walked all the way to the house where the old couple lived and waited patiently.

But the two were lucky, and soon the old man walked out of the room.

"I'll go first, you stand here and don't move." After saying that, Tang Ze opened the car door and walked out, passing by the other person like a passerby.

Seeing the other party disappear around the corner, Tang Ze turned back and got back into the car.

"How is it? Did you find anything?" Conan asked anxiously, "If not, we need to hurry up, or we might lose him."

"Let's go. There's no need to follow now. Let's take a long-term approach."

As Tang Ze drove away, he said solemnly, "He's in disguise. There are traces of disguise on his face. Although his technique is very sophisticated, he can't hide it from me."

After all, Tang Ze also knows the art of disguise, so even if he has doubts in his heart, he can still find some clues by carefully identifying.

What's more, it is easier for him to judge whether the other person is a human than for others, because his super sense of smell is the natural nemesis of disguise!

Just when he passed by the old man, Tang Ze's super sense of smell was at full power.

At that moment, he smelled too many scents on the other person.

Food, shampoo, women's cosmetics, and even a hint of perfume.

The last two smells should undoubtedly be the smells of the other person's companion, which is enough to explain the problem.

After all, it is understandable for these things to happen to young women today, but it is a bit abnormal if it happens to an old woman in her seventies.
