"Damn, could it be that he disappeared into thin air?"

Hearing this, the Xiao Wang was shocked.

"It's still hard to say. We'll have to go to the scene to make a judgement. But from the contents of the police call, I'm afraid this case will be very troublesome!"

As he spoke till here, Cui Chao couldn't help but frown.

Half an hour later, they arrived at the residential area where the police were staying.

This was a middle-sized, low-grade residential area. The price of the housing was not very high, and the residential area had gone into the modern era as well! Therefore, the moment they entered the small district, Cui Chao was the first to come to a conclusion: this shouldn't be an incident of kidnapping!

When they arrived at Mr. Cai's home, they immediately began investigating.

The Technician entered the bedroom of the missing daughter of the Mr. Cai first, and began to inspect his, while Xiang Anjie and Cui Chao stayed in the living room with the Mr. Cai to learn more about the situation.

Seeing that Xiao Wang had opened the book and Xiang Anjie had also opened the recording pen, Cui Chao asked: "Alright, tell me the details!"

"En!"

The couple in front of him were clearly anxious. Mr. Cai said straightforwardly: "Last night at 10 o'clock, our daughter Cai Rui was still at home. After she finished showering, she went back to her room! The two of us went back to our room and slept. We didn't feel anything for the whole night, but when we woke up in the morning, we saw that our daughter hadn't come out, and the door to our room was also closed. We knocked on the door to wake her up, but there was no reply from inside.

It really is a little tricky!

Hearing this, Xiang Anjie secretly thought to himself: A human being can actually disappear into thin air, isn't this a little too strange?

Sure enough, Cui Chao's face also became stern: "Did you guys hear anything tonight?"

"No!"

The couple shook their heads, "We are both people who sleep very lightly. If there is any movement, we will wake up immediately. But tonight, we didn't feel anything. We only opened our eyes the next day!"

"Could it be that your daughter went out while you were asleep?"

Xiao Wang who was taking notes could not help but ask.

"No, absolutely not!"

Mr. Cai said with determination, "Every night when we go to sleep, we lock the door from the inside. This kind of lock can only be locked from the inside, if our daughter sneaks out, the door would definitely not be locked from the inside, but when we wake up in the morning, the door would still be locked from the inside, which should mean that she hasn't left!"

"If you didn't go through the gate …" Will you go out the window? "

After all, he was just a living person who disappeared into thin air. At this moment, Xiao Wang started to consider other matters.

"I'm afraid that's impossible!"

Xiang Anjie walked to the window and looked outside: "Even though his house is on the sixth floor, the windows are all equipped with an anti-theft net. Normal humans wouldn't be able to go out through the window, and a girl wouldn't go out from the window at night, right? You must know that this is the sixth floor! "

"Then that's strange …" It's impossible for me to leave by any means, and now that I'm not at home, I can't possibly have disappeared into thin air, right? "

Hearing this, Xiao Wang felt that it was a bit inconceivable.

Not long later, the Technician who had cleaned up the scene walked out from their room and reported their preliminary findings.

Firstly, the phone of the girl called Cai Rui was placed on the desk, and her bed also showed that she had probably slept on it last night. This was because two long hair had been found on her pillow, and in the other room, there were also her fingerprints and footprints.

After hearing Technician's report, Cui Chao lowered his head and thought for a while, "How about this, Xiao Wang, you two go downstairs with Xiao Li to look for the monitor probe near this district. It would be best if you look directly at the exit of this district to see if you can find any valuable clues from the surveillance videos from 10 o'clock last night to this morning!"

"Yes sir!"

Xiao Wang and Xiao Li nodded and then left.

On the other hand, Cui Chao and Xiang Anjie walked into Cai Rui's room.

The moment he walked into the room, Xiang Anjie felt that it was filled with the style of a young lady. The entire room's decorations were pink in color, just like Bai Linger's room! As for the items in the girl's room, they were arranged neatly. It was obvious that this girl liked cleanliness.

However, her bed was in a mess right now, which meant that she must have disappeared while sleeping yesterday.

"Angel, let's investigate the rest of the room separately!" With that, Cui Chao started to search in the corner of the room, and after he nodded, Xiang Anjie also went to look at the other side.

The item in front of him just happened to be the little girl's desk. Xiang Anjie took a look at the items on it, and finally, his gaze stopped on two of the items.

One was a clean ashtray, while the other was a lighter!

Strange, why would a girl have an ashtray and a lighter on her desk?

Seeing that, Xiang Anjie was a little surprised. He placed the ashtray under his nose and took a whiff, then suddenly frowned.

Although the ashtray looked clean and spotless, there was a faint smell of smoke coming from it. This smell of smoke was not like the smell of burning cigarettes. Instead, it seemed like the smell of some paper being lit.

Moreover, Xiang Anjie always felt that this smell was a little familiar, as if he had smelled it before, but he was unable to recall it in a short while.

"Did you find anything?"

Seeing Xiang Anjie's strange expression, Cui Chao walked over and asked.

Xiang Anjie nodded his head: "Leader, look, this ashtray and lighter!"

"Hmm?"

Cui Chao also discovered the strangeness of these two things, and couldn't help but frown: "An eighteen year old Little girls that attends university, could it be that he's still smoking?"

"It's indeed strange, but it's not the strangest thing. The strangest thing is this ashtray. Captain, do you smell it?" There's a special smell of smoke on it! "

"Is that so?"

Hearing that, Cui Chao picked up the ashtray to smell it, but in the end, he shook his head: It doesn't have a smell, at most it's just the smell of cigarettes, right?

Only now did Xiang Anjie remember that his sense of smell was much more sensitive than a human's, so he might not be able to smell anything that he could.

At this time, Cui Chao had already walked out of the room, and called Cai Rui's parents in.

"Does your daughter smoke?"

Cui Chao asked directly.

The couple shook their heads. "If she doesn't smoke, then no one in our family will!"

"But why would she have an ashtray and a lighter in her room?"

Cui Chao pointed to the items on the table and asked.

Upon hearing this, and seeing the ashtray and lighter on the table, the couple was also taken aback. Why is this thing here?

Cai Rui's mother carefully examined these two things: "Isn't this placed in the living room to entertain customers? Why is it here? "

"That's right …" Could it be that Little Rui brought it in herself? "

"Then why did she come in with that thing? Is it so hard that you have to smoke? "

"Impossible, daughter, you still don't know? When did she smoke? And look, there's no cigarette butts in the ashtray! "

"Then what is the purpose of her thing?"

"How should I know?"

"It's all because you don't usually care about your daughter that she disappeared!"

"Stop talking about me. Can't you be more concerned about her?"

It could be seen that the couple was in a hurry. They seemed like they were about to start a fight.

There was nothing Cui Chao could do but to comfort the two of them while he continued to investigate.

However, after some investigation, he could not find any other valuable clues. After all, university girls were often living in schools, and their families only came back after the holidays, so he was afraid that there were not many valuable evidence.

So at the end, Xiang Anjie's gaze stopped on Cai Rui's phone. He tried it and discovered that the phone was locked! But luckily it was a fingerprint password, so after bringing it to the station and creating the model of Cai Rui's fingerprint, it should be able to be undone.

"Sigh, I'll probably get the other evidence from this phone!"

With that, Xiang Anjie put the phone into his evidence bag, and after a moment of hesitation, he put the lighter and ashtray into the bag as well.

When he walked out from the room, he saw that Cui Chao had already comforted the couple, but the two of them were still worried about their daughter. Maybe it was because their daughter's disappearance was strange, but the two of them also had a bad premonition.

"Captain, bring the items back to the technical department for them to have a good look!" With that, Xiang Anjie gave the item to the Technician.

Cui Chao nodded his head, then said to Technician: "Carefully check the sewer and drain of this kitchen's restroom, it would be best if you could do a blood test."

Hearing this, Xiang Anjie couldn't help but frown, and then answer in a small voice. "Captain, you're worried …"

Cui Chao shook his head, signalling him not to continue: "I do not want to think like this either, but this matter is truly strange, a living person disappearing into thin air is impossible, so we have to consider all possibilities!"

Although he knew what Cui Chao said was reasonable, but when he thought about how he actually suspected this couple, he couldn't help but feel uncomfortable in his heart.

Fortunately, after some investigation, Technician did not discover any blood reactions at the drain. This also ruled out the possibility of his parents killing his daughter. Hearing this result, Xiang Anjie and Cui Chao could not help but heave a sigh of relief.

Just at this time, Xiao Wang and Xiao Li, who went out to investigate, returned as well. After a round of investigation, the two saw that several monitor probe s had been filmed, but they did not see Cai Rui. Furthermore, according to the security testimony, they also did not see anyone leaving the small district during the night.

"This is truly strange. A living person didn't leave his home, yet there was no one at home. Did he really disappear into thin air and disappear into thin air?"

Seeing that the situation had reached this point, Cui Chao could not help but mutter under his breath.

"Police Comrade, where did my daughter go? Could it be that we can't find it? "

At this time, Cai Rui's parents were also getting anxious.

"Uh, don't be in such a hurry. The police will definitely investigate this matter thoroughly. You can rest assured about this!"

After comforting the couple for a while, Cui Chao brought the rest of the people back to the station. After all, the investigation was already done in the family, and if they still needed to investigate, they could only do so through investigation outside. Hence, he planned to return back to the department to summarize the situation first, and then discuss the plan for the investigation.
