I'm a criminal investigation major, and you want to take me to fight drug trafficking?

Chapter 407: Hidden Things.

When Guan Cai heard Li Xuan's words, he also dusted himself off.

Prepare to follow him to Yang Hongqing's office.

But at this time.

Li Xuan's cell phone suddenly rang.

Toot toot…..

He took out his cell phone from his pocket and looked at it.

It was Gao Zhun who called.

Now he is responsible for monitoring Yang Hongqing.

Li Xuan answered the phone doubtfully and asked.

"Old leader, what's wrong?"

Gao Zhun's voice came from the other end of the phone.

"Li Xuan! Nothing happened."

"How is the situation over there?"

Upon hearing this, Li Xuan immediately answered.

"No usable clues have been found so far."

Gao Zhun sighed when he heard this.

"You've made a big fuss this time."

"If we can't find evidence, I don't know how this will end!"

"Forget it, let's not talk about this!"

"I sent someone out to buy food for everyone."

"What would you like to eat?"

Li Xuan smiled and said when he heard this.

"Old leader, don't worry!"

"Just eat whatever you want."

"I'm not too picky about food anyway."

"Old leader, you......"

When he said this, Li Xuan was suddenly stunned.

An idea flashed through his mind.

He hurriedly asked Gao Zhun.

"Old leader, have you arranged meals for Yang Hongqing?"

Gao Zhun was a little confused when he heard this, but he still spoke after hearing the urgent tone.

"His was arranged long ago and has just been delivered."

"Someone has brought it in for him."

"What's wrong? Is there something wrong?"

Upon hearing this, Li Xuan immediately yelled into the phone.

"Take the things down immediately!"

"Yang Hongqing didn't let him eat or see anyone."

"To be more precise, don't let him eat second-hand food!"

He immediately thought of the two criminals who died of poisoning in the Banyan City Police Station.

These are lessons learned through blood and tears.

With the means and skills of the people behind Yang Hongqing.

It wouldn't be difficult to poison the food again.

Besides, this food has changed hands several times.

There are so many ways to manipulate it!

There is no way not to guard against this happening.

Yang Hongqing can be said to be the most important person in their hands now.

After Gao Zhun heard Li Xuan's words on the phone.

He also hurriedly shouted to the police officer who was holding the food and pushing open the door to walk in.

"Wait a minute! Bring me the food first!"

The policeman was slightly stunned when he heard this.

But he still closed the door and took back the food he had packed from outside.

Gao Zhun placed the food in a white plastic takeaway box on the table.

I opened it carefully and checked it.

But he found that there seemed to be nothing special about the meal.

However, he still handed it to Song Yonghua very carefully.

"Take it back for testing immediately!"

When Song Yonghua heard this, he nodded immediately.

Then he picked up the food and turned to walk outside.

Gao Zhun spoke to the criminal police who were guarding the door and inside at the same time.

"From now on, I will personally guard Yang Hongqing."

"No one except Li Xuan is allowed to approach!"

"Yes!"

The four detectives inside and outside immediately stood at attention and shouted in a stern voice.

Gao Zhun walked into Yang Hongqing's office.

At this time, the wealthy man from Guangnan Province was sitting at his desk with a worried look on his face.

The ashtray in front of me was already full of cigarette butts.

But he still kept ordering one cigarette after another.

It was obvious that Yang Hongqing was very anxious at the moment.

Gao Zhun just glanced at him and didn't say anything.

He just walked over to the sofa and sat down.

Seeing this, Yang Hongqing grinned, a smile uglier than crying, and said to Gao Zhun.

“I don’t know if I should say it’s an honor.”

"Or should I say you're a little too flamboyant?"

"The deputy director of a provincial department actually came to look at me in person."

"This is truly surprising! Deputy Director Gao!"

Gao Zhun just smiled slightly when he heard this.

But he still didn't intend to speak.

Except that his eyes were fixed on Yang Hongqing.

There are no other actions.

Seeing his expression, Yang Hongqing pretended to be calm and picked up a folder at hand.

Then he seemed to be fully focused on it.

But he seemed to be concentrating on the folder in his hand.

But in fact, his eyes would look in the direction of Micro Motion from time to time.

Even most of my peripheral vision was focused on Micro Motion.

He looked at Gao Zhun without any intention of looking elsewhere.

Yang Hongqing was panicked, he was really panicked.

The deputy director of the provincial department came personally to monitor him.

You can tell with your big toe that they must have discovered something.

Although that might not be the place.

Because he believed that it would be impossible for ordinary people to discover his arrangement.

But...it's difficult!

Beads of sweat the size of beans slid down Yang Hongqing's forehead.

........

After Li Xuan hung up the phone, he gave up the idea of ​​going back for interrogation.

Instead, he continued to search in the stairwell.

But they did encounter a lot of trouble.

No matter how hard they searched, they couldn't discover the secret of this place.

Just when Li Xuan himself began to doubt whether he had made a wrong judgment?

Suddenly he looked up at the fire hydrant door in the stairwell.

Having a fire hydrant door is not unusual.

But why in the stairwell?

Generally speaking, fire hydrant doors should be placed in public shared spaces such as corridors and halls.

This is so that it can be used immediately in case of fire.

But why is there a fire hydrant door on the right side of the stairs?

This doesn't make sense! Do I have to stand on the stairs to open the fire hydrant to use it?

You should know that the width of the stair steps is only about 12 centimeters.

A normal person would stand on this staircase, open the fire hydrant door and take out the things inside.

Is this location too weird?

If we must follow the stairwell, would it be more reasonable to place it in the corner of the open space next to the fire door?

Li Xuan walked to the fire hydrant door and knocked.

I saw that this was a built-in fire hydrant door.

The door panels are made of wood and painted.

There was a seal on the crack of the door on one side.

Li Xuan removed the seal and opened the fire hydrant door.

There were only two cans of powdered fire extinguishers, a fire hose and an interface inside.

It doesn't seem to be any different from the others.

I reached out and knocked on various places inside the fire hydrant door, but there was nothing unusual.

There are strong solid walls all around.

Just when he thought it was just his own illusion.

The marks on the fire hydrant interface instantly caught his attention.

The fire hydrant interface, which had been left unused for a long time, showed signs of wear and tear.

The water hose next to it also shows signs of long-term use.

And it seems that this fire hydrant door is a little too clean.

Li Xuan reached out and touched the marks on the interface.

For a moment a smile appeared on his face.

found it!
