"It's classified."

After Zhao Bin said these four words, he turned the topic back, "I heard that someone is missing, so I brought someone over." What's going on here? ”

As he spoke, he asked the witness, Ruan Lingyu, to take them to the scene of the crime.

"This needs to be used as an investigation, please get out of here."

After Zhao Bin came to the toilet on the fourth floor and showed his ID, the people around him could only leave and go to the toilet somewhere else.

Soon, the people brought by Zhao Bin pulled up the cordon, and Jiang Bai finally had the opportunity to enter the women's toilet to check.

"Let's go, go in and have a look."

After Zhao Bin learned the general situation from Ruan Lingyu and Ruan Ting, he took Jiang Bai and Che Hao into the women's toilet.

Jiang Bai glanced at the women's toilet, the lights were normal, and there were five squatting toilet cubicles on the left, just like ordinary public toilets.

The only difference may be the "infrastructure" of this toilet.

Ordinary public toilets can be very dirty, but the ones here look like they are often cleaned.

Not only is the floor clean, but even the inside of the cubicle is clean. There is a roll of paper in one side of the cubicle, and the service is very good, so that customers don't have to go to the toilet without paper.

While the others were still checking the rest of the toilet, Jiang Bai and Che Haoqi brushed their heads up.

They want to look at the ventilation ducts.

Since Ruan Lingyu and Ruan Ting confirmed that no one came out of here, the kidnappers should have escaped along the ventilation duct when they caught Yan Xiyue.

When they were surveying with the criminal police team, the general manager of the mall also rushed to hear the news.

"Guys, what's going on here?"

The general manager asked as he walked in, "I'm the general manager of the mall, and I'm in charge of the entire mall's operations. ”

"Something like this......"

After Zhao Bin explained to the general manager, he found that the general manager's expression was a little strange.

"It's hard to ...... Is it true......"

He muttered to himself.

"What's true?"

Jiang Bai asked, "Is there something going on with the toilet on the fourth floor?" ”

"Uh, no, no, it's just some unpopular legend."

The general manager smiled, "Everyone is joking." ”

"Then tell us about it and relax."

Zhao Bin looked at the general manager's appearance was wrong, and asked with a frown.

"It's that this mall has had murders before, it seems that when it was built, I heard that a worker's daughter was buried in the toilet on the fourth floor, so many people disappeared when it was built!"

The general manager explained, "I heard that the investors of the mall at that time found a lot of high-level talents to calm down the question. However, two or three years ago, in order to cooperate with the construction of the development zone, the mall was renovated, and it was originally a sealed room, and some shareholders felt that it was a waste, so they expanded it into a toilet. ”

"Is this the place where the body was buried?"

Jiang Bai asked.

"I don't know about this, it's a gimmick, no one knows whether it's true or not, I'm the general manager who came here after the renovation, and I don't know the previous situation."

The general manager explained that Jiang Bai noticed that there was some sweat on his forehead.

It's not that he doesn't believe in ghosts and gods, but he doesn't believe in unfounded claims. Rather than this gratuitous story, he prefers to believe that someone secretly kidnapped people through this ghost and god theory.

After all, the kidnapping letters are here.

"We still need to investigate, you go back first, if there is anything we will come back to you."

Zhao Bin said and asked the general manager to go back first.

The criminal police team was still investigating, and he walked to Jiang Bai and Che Hao, "Did you find anything?" ”

"Can you check the ventilation ducts?"

Che Hao thought about it and said, "Jiang Bai, I feel that the ventilation duct can't accommodate two people. ”

They were looking up at a vent.

The vent has obvious signs of being moved.

Jiang Bai looked around, and the vent was facing the pit closest to the window.

"Did Yan Xiyue enter here at that time?"

Jiang Bai asked Ruan Ting.

"Yes, I went in this one on the side, and she was here at the time."

Ruan Ting recalled, "When I asked her when I finished going to the toilet, she said that it would take some time, so I came out first." ”

Her words indirectly proved that before she left, Yan Xiyue was still in that pit.

"Did you notice anything out of the ordinary?"

Che Hao asked casually, "For example, the ventilation pipe." ”

"In that case, the ventilation duct is noisy for a while, and there is no other movement."

Ruan Ting replied truthfully.

"Take a look."

As he spoke, the detective team members brought a ladder and opened the fence of the ventilation duct.

Jiang Bai and Che Hao entered the ventilation duct one after the other.

It was very dark in the pipe, and Jiang Bai and Che Hao invariably turned on the flashlight in their mobile phones and shone in two directions.

They are located right at the intersection of ventilation ducts. Quite a bit of fresh air was blowing back and forth around them.

Under the light of his mobile phone, Jiang Bai found that the ventilation duct on his side was covered with dust, and it seemed that he had not cleaned it for a long time.

"Take a look over here."

Cha Hao made a discovery, his flashlight was shining on some marks.

Jiang Bai turned around with difficulty, and it took a lot of effort to turn around.

He found some traces of towing from the location where Che Hao's flashlight was illuminated.

"It's hard to turn your head here, and it's too hard for two people to pass."

Che Hao said and followed the trail of dragging, "What tools should the kidnappers use to help Yan Xiyue drag all the way." ”

"First of all, he has to make Yan Xiyue unconscious."

Jiang Bai said and suddenly thought of something, "Wait, how did the kidnappers know that Yan Xiyue would definitely be facing this ventilation duct at the last pit position?" ”

He frowned as he spoke, there was so much to be said about this matter. Like the previous kidnapping case of the thousand-faced doll and Ruan Jin, there are contradictions everywhere, which only increases the difficulty of solving the case.

"According to what Ruan Ting said, there should be no one in the other pits at that time."

Che Hao analyzed, "It's strange. ”

He thought the same as Jiang Bai, either Ruan Ting lied and she knew all this, or there were other people here at that time - kidnappers!

"Let's go down first."

Che Hao said as the first to get down from the ventilation duct and told Zhao Bin about the strange drag traces.

"Leave this to my teammates."

Zhao Bin said, directing the two criminal police team members to enter the ventilation duct to trace the trail of dragging.

"Any other clues?"

"Not yet."

Jiang Bai planned to wait until he went back to ask Ruan Ting about the specific situation.

He felt that Ruan Ting would not tell the truth on such an occasion.

It didn't take long for the criminal police team to end the investigation of the scene, and Jiang Bai followed Ruan Lingyu and Ruan Ting to the criminal police team to make a record and then returned to Ruan Ting's house.

On the way, Jiang Bai has been paying attention to Ruan Ting and Ruan Lingyu's reactions.

Ruan Ting was very calm, giving Jiang Bai a strange feeling. However, she and Yan Xiyue haven't been together for long, so it's normal.

And Ruan Lingyu is still in a hurry.
