After analyzing and realizing this, Tang Ze decisively activated his super sense of smell to investigate.

He had no choice but to be cautious when it came to poisoning. After all, they were in a ramen restaurant and were about to eat the ramen made by the manager.

Not to mention that the other party may poison and kill people at any time, what if something goes wrong and the poison gets into their mouths?

The original plot changed the moment he intervened, so he naturally had to be careful not to die in such an obviously stupid way.

However, when his super sense of smell was activated, his concerns turned into doubts.

Because he noticed that there was poison on the other person's glasses frame, to be precise, the small part where the left glasses leg and the lens were connected was poisonous.

Knowing the location of the poison, he naturally had no worries.

After all, the poison is already there, which means that the other party may have come into contact with the poison. Then, you just need to watch the other party with the utmost caution to prevent him from putting objects that he has touched into his mouth and eyes.

Of course, he had no intention of eliminating the source of danger immediately. After all, solving the problem of the poison would only solve the crisis on the surface, but the crisis inside would continue to lurk.

There is no way to prevent murders unless the poisoner is found. Even if the poison is eliminated, there may be other methods of killing in the future.

There is even the possibility of bigger troubles arising from the younger brothers controlled by Xijin Desheng, a not-so-clean guy.

So it would be better to wait and see for the time being, collect information, and see if the culprit can be found directly.

Fortunately, this time he was able to directly identify the criminal.

"What? We already know the culprit!" Nishijin Desheng excitedly said after hearing Tang Ze's words: "Who is it? Who wants to kill me?!"

"Manager Yanaka... that should be his name, right?" Tang Ze looked at the middle-aged man with an uneasy expression and smiled, "You were the one who poisoned me, right?"

"How is that possible? He just walked in the door!"

Upon hearing this, Ogura Gongya said anxiously, "Besides, he sat down in the seat near the door as soon as he entered. There were you two between us, how could he have poisoned him?"

"Of course it's not possible here, but what if it's in his shop? That would be entirely possible, right?"

Tang Ze smiled indifferently and said, "Don't forget, when Mr. Nishijin Desheng was talking to you, he said that before coming to your shop, he went to the shop of the manager Yanaka to get a haircut.

When Manager Taniyama just came in, although he refuted Mr. Nishizu's remarks, he also indirectly proved that he had indeed cut Mr. Nishizu's hair.

In a barber shop, it is normal to help customers keep things like glasses.

Mr. Nishizu had not had any contact with other people since he entered the door, and the poison was located on the left leg of his glasses.

In other words, there was no possibility that the boss and the clerk who met Mr. Xijin for the first time in the house could have poisoned him. The opportunity to poison him was only when he was in the barber shop.

After all, glasses are very personal items, and generally no one would take other people's glasses.

In other words, if you touch other people's glasses casually, you will definitely be suspected.

After Mr. Xijin realized that his glasses had been pushed under the quilt, he did not immediately realize that someone had deliberately taken his glasses.

In other words, no one touched his glasses unexpectedly today.

On the other hand, someone naturally came into contact with Mr. Nishizu's glasses and successfully smeared the poison on them."

"Hey! Yanaka!! You were the one who poisoned me!!"

After hearing Tang Ze's reasoning, Nishijin Desheng said angrily, "Today, you are the only one who has the chance to touch my glasses. What else do you have to say?!"

"Wait a minute! Even if he really did those things, how can we be sure that he touched the poison!" Seeing Nishizu Tokushin getting angry, Ogura Kyouma quickly stood up to argue.

"Yeah, it's not like we're controlling his actions with hypnosis, so how could he possibly be so obedient as to touch the poison?" Ohashi Ayaka also echoed.

"No, he will definitely touch it." Tang Ze shook his head and looked at Conan and said, "Go and demonstrate it."

'You're really good at ordering people around.'

Conan was secretly complaining in his heart, but on the surface he still agreed obediently.

After jumping off the chair, he walked out the door directly under everyone's gaze.

"What does this mean?" The impatient Ohashi Ayano couldn't help but ask.

"Detective Karasawa said that's where he was bound to touch it because if someone like us who wear glasses suddenly walks into a warm place like a ramen shop, our glasses will become like this."

"It's foggy!?" Kogoro Mouri asked in surprise.

Tang Ze smiled and said, "Yes, and once the glasses are fogged up, it is natural to take them off and wipe them with a glasses cloth.

When I first entered the store, Mr. Nishizu wiped his glasses.

At this point, Tang Ze looked at Nishijin Desheng and said, "You should be left-handed, right? But you seem to be very comfortable with your right hand as well."

"Ah... I was left-handed when I was little, but my parents later corrected me and made me right-handed," Nishijin Tokusho answered honestly. "So I can use both hands."

"Mr. Yanaka, you are very observant. I'm afraid you have been paying attention to his habits for a long time, right?"

Tang Ze looked at the store manager Yanaka and said, "Otherwise, you wouldn't be able to find the poison location so accurately, as if you could see through the other party's future actions.

The reason you came back to this store was actually to prevent other customers from being killed by you by mistake, right?

After all, if Xijin Desheng passed chopsticks to other guests, it might cause unnecessary casualties.
