Seeing this, Xin Teng Wuyue was slightly startled, not understanding why he had such a big reaction.

"What's wrong?"

Xu Dong didn't look at her, but picked up the teapot, put his finger into the tea spout, and rubbed it gently.

Suddenly, there was a thin layer of greasy substance on my fingertips.

"There is a poisonous frog in the world called the poison dart frog."

"Its size is very small, only one centimeter. Even if it is larger, it does not exceed five centimeters."

"It looks very beautiful, but the toxicity in its body ranks among the top five in the world. It only takes a little bit of venom to kill a person easily."

"And the mucus on its surface is also toxic and can even be processed into a paste."

"After being heated and dissolved, it will form a colorless and odorless poison. If accidentally eaten, internal organs will bleed within three minutes."

"But this kind of bleeding is very slight. It's called hemorrhage in medical terms. It's drop by drop, and you can't even notice it."

"In another two minutes, the amount of bleeding will increase, changing from water droplets to gurgling water."

"In the end, you will suffer from internal bleeding and die of despair."

Having said this, Xu Dong looked up at the waiter and asked coldly, "If I guess correctly, is this the poison used on the spout of this pot of tea?"

After the words fell, Xin Teng Wuyue's pretty face suddenly turned pale, and she stood up and subconsciously moved away.

Thinking of the cup of tea she almost drank just now, a layer of goosebumps appeared on her fair arms.

The waiter standing aside also changed his expression.

"I, I don't know!"

"You brought the tea in, how could you not know?"

Xin Teng Wuyue shouted with a cold face.

"No, I really don't know!"

"I've never heard of poison dart frogs!"

The waiter looked very panicked, his face was pale, and there were big beads of sweat on his forehead.

Xu Dong stared at him closely for a while, then shook his head, "He didn't do it."

"Thank you sir for your trust, thank you!"

Hearing this, the waiter finally breathed a sigh of relief.

Xu Dong waved his hand, "Go and call your manager over."<

"Yes Yes."

The waiter was very cooperative and immediately turned around and walked out of the box.

"Are you sure he didn't do it?"

After the others left, Xin Teng Wuyue slowly sat on the chair and asked.

Xu Dong nodded without explaining anything.

There was nothing wrong with the waiter's reaction at first glance.

"Huh~~~"

Xin Teng Wuyue became a little nervous. "Then tell me, who is attacking us? Tsukiyage Chigusa?"

"not necessarily."

After Xu Dong pondered for a moment, he slowly shook his head.

Tsukage Chigusa must have been dealing with a series of troubles caused by the job fair recently, and she had no time to deal with herself.

And this poison was obviously prepared long ago.

But, if not her, who else could it be?

Xu Dong couldn't help frowning and making calculations.

Neither of them spoke and waited quietly. Three minutes later, the waiter hurried over with the restaurant manager.

"Sorry, I'm really sorry."

"Both of you, I didn't know this would happen."

"However, I want to confirm that this tea mouth is really smeared with poison?"

Xu Dong glanced at the restaurant manager and said, "Don't believe it? You can take a sip."

He poured a cup of tea and handed it to the restaurant manager.

"No no no..."

The restaurant manager turned a little pale and waved his hands repeatedly.

"Who made this pot of tea?"

Xu Dong didn't talk nonsense and asked straight to the point.

"I'm a part-time college student."

The manager was very cooperative.

"Take me to the monitoring room and take a look."

Xu Dong stood up and walked outside.

"This..." the manager hesitated, "I'm afraid this is not good. Only official personnel can enter the control room. For private purposes, there are no big boss regulations. Yes

Not allowed to enter.”

"Okay, then I'll call the police now."

Xu Dong quickly took out his mobile phone.

"No!" The manager broke out in a cold sweat. "Sir, what do you think the restaurant can give you appropriate compensation?"

"Take me to the control room." .??.

Xu Dong said coldly, "Otherwise, I will expose this matter to the media and let them publicize it. I believe that once it is exposed, no one will risk their lives to come to your place to eat, right?"

Upon hearing this, the manager's face instantly turned ugly, and then he nodded with difficulty.

"Then come with me!"

Soon, the group of people arrived at the monitoring room.

The manager opened the surveillance video of the back kitchen.

What can be seen is that the kitchen space is still very spacious, with eight chefs working, busy and orderly.

There are many apprentices nearby to help.

"fast forward!"

Xu Dong gave instructions in a calm tone.

The manager was very cooperative and his fingers moved flexibly on the keyboard.

"Pause!" Xu Dong suddenly shouted.

The scene was frozen, and you could see a man wearing a black jacket appearing in the kitchen.

Due to the angle, I couldn't see the man's true face clearly, but looking at his sneaky appearance, it was obvious that he had bad intentions.

"Who is this person?"

The manager came closer, took a look, and then shook his head, "I don't know, maybe it's a customer!"

Xu Dong motioned for him to continue playing.

The mysterious man moved very quickly. He rolled on the spot and arrived at the food delivery area without disturbing anyone.

Then, he seemed to be looking for the box number. After confirming it, he reached out and touched the tea spout.

The whole process went smoothly and took no more than three seconds.

After he was done, the man ducked out of the kitchen again.

The chefs and apprentices were still busy making dishes in an orderly manner, and no one noticed this scene.

"That's him." Xu Dong

Said in a deep voice.

"Um?"

The manager suddenly moved closer again, then zoomed in on the screen and said, "I seem to have some impression of this person."

"By the way!" He patted his head, "His name is Matsushita Daisuke. He is a regular customer of the store. He comes here once or twice a week."

"What are you doing?" Xu Dong frowned and asked.
