"It's okay, just investigate, don't think about it."

After saying it to him, Lin Yao walked out directly.

The two of them couldn't wait and drove directly to Zhou Jue's residence.

Ten minutes later, Yao Jin parked the car, and the two looked up.

This is an apartment, which belongs to the more economical type.

"Let's go, go up."

After saying that, the two walked in.

"Knock knock!"

"Open the door!"

After knocking on the door for a while, Lin Yao and the two glanced at each other.

"Brother Yao, there's no movement in there at all, is he in there?"

Yao Jin couldn't help frowning and looked at Lin Yao and said,

"Why don't you just break in? It doesn't seem like a good thing."

While the two were struggling, the door on the opposite side opened, and a young man in his twenties walked out in pajamas with sleepy eyes.

After he saw that it was Lin Yao and the others who knocked on the door, he was stunned for a moment, and then asked:

"You guys. . . What's the matter?"

"Hello, comrade. Do you know if the people who live in here are not there?"

Lin Yao turned to look at him and asked.

"He's moved away and doesn't live here."

The guy said directly.

"What? Moved away? When's it?"

When Yao Jin heard this, he immediately asked with some excitement.

"He moved out two days ago, and he was in a hurry."

The guy thought for a moment, and then said.

Lin Yao and the two immediately glanced at each other.

Then, Yao Jin whispered next to Lin Yao:

"There must be something wrong with this kid, but he moved away at this time, he must have run away!"

Lin Yao frowned and didn't speak, and after a while, he looked up at the guy and asked:

"Do you know his phone number?"

"Phone number? Well. I did have one, he bought furniture before, and then he wasn't there during the day, and he asked me to help him collect the goods, and he gave me his phone."

The guy thought about it, and then quickly said.

"Then please give him a call now."

Lin Yao leaned over directly and said to him.

"Then I. . . Say what?"

The guy couldn't help but ask.

"You just say that the landlord is here, and there was a problem with the utility bill before, ask him where he is now."

"Okay, understood."

The guy resolutely agreed, with a serious expression.

At the moment, he has a sense of mission to participate in major tasks.

Then, he took his phone out of his pocket and rummaged through the address book.

"Found it."

With that, he pressed the dial button.

Lin Yao and Yao Jin stared at his mobile phone screen tightly, listening to the sound of "doo" coming from inside.

"Hey?"

Suddenly, the phone answered, and a voice came from inside.

Lin Yao and the others were suddenly excited.

"Hey, brother, where are you now?"

The guy hurriedly asked on the phone.

"What's wrong, what's the matter?"

The voice from inside was cold.

The young man glanced at Lin Yao and them nervously, and then said:

"Ah, what, the landlord came over just now and said that there was a little problem with your utility bill, and wanted you to come and take a look."

After finishing speaking, he looked at Lin Yao again.

Lin Yao nodded slightly.

The other end of the phone said lukewarmly:

"Oh, I'm back to my hometown now, I don't have time to go there, so be it."

After saying that, he hung up the phone directly.

"He's hung up."

The guy pointed to the mobile phone and said to Lin Yao

Said.

"He's back home!"

Yao Jin said directly with some excitement, then turned his head to look at Lin Yao and asked:

"Brother Yao, what should I do?"

"Don't worry."

Lin Yao glanced at him, then turned his head to look at the young man, squeezed out a slight smile and said:

"Okay, thank you."

"It's okay, it's okay, it's supposed to be."

The guy waved his hand again and again.

Then, Lin Yao and Yao Jin walked out of the apartment first.

"Brother Yao, that kid is hiding back in his hometown now! No one believes him when he says he's fine!"

After coming out, Yao Jin said to Lin Yao excitedly.

"Don't worry."

Lin Yao couldn't help but look at him and said,

"We don't have any evidence now, and we can't act rashly."

"In this way, let someone investigate where his hometown is, and have a number in mind, but don't act."

Yao Jin immediately nodded, and then said:

"Okay, understood, I'll let them know."

Yao Jin took out his mobile phone and immediately arranged it.

At this moment, Lin Yao's mobile phone also rang.

Lin Yao took it out and saw that it was a call from someone from the technical squadron.

"Hey?"

"Hey, Officer Lin, I have to tell you about something here."

The person on the other side of the technical squadron immediately said.

"What's the matter?"

Lin Yao raised his eyebrows.

"We found a mobile phone under the sofa in the living room, and after testing, it was found to be the same phone that posted on the forum."

"What was found under the sheets should be the mobile phone he discarded before, which is useless to us."

The technician immediately said to Lin Yao.

"That's right."

Lin Yao nodded.

Although there are new discoveries, they are not very useful for solving the case.

"And"

Immediately afterward, the technician continued,

"We found a lot of saliva on the screen of our phone."

"What? Saliva?!"

Lin Yao and Yao Jin immediately frowned, secretly pondering.

Got a lot of saliva on your phone screen?

Could it be that the deceased had a habit of licking at the screen?

"What's going on? Is there any inference as to where this saliva came from?"

After a moment, Lin Yao couldn't help but ask.

"We've tested it, and the saliva on this screen doesn't belong to the deceased."

Immediately afterwards, the technician said to Lin Yao.

"If it's not the dead, whose is it? The murderer's?"

Lin Yao couldn't help but be stunned for a moment, and then asked.

"! The murderer still has this habit? After killing someone, lick the victim's phone screen wildly?"

Yao Jin, who was on the side, asked with wide eyes when he heard this, and couldn't help but shudder.

"We're still testing this, but I'll tell you about this discovery first."

The technician said hesitantly.

"Okay, I see, we'll go now."

Lin Yao nodded with a solemn expression, and then said.

After hanging up the phone, Lin Yao said to Yao Jin:

"Let's go, get over there. This may be the only clue found that has anything to do with the murderer."

"Well, okay, we should compare this saliva with Zhou Jue's, my intuition tells me that Zhou Jue has a problem."

Yao Jin nodded and said.

Coming to the technical squadron, Lin Yao and the two directly pushed the door and walked in.

"How?"

Lin Yao looked at the technician who was conducting the test and asked.

"This."

The technician's expression was somewhat complicated.

"What's wrong? Any questions?"

Seeing him like this, Lin Yao couldn't help but ask suspiciously.

"Anyway, there seems to be something wrong with the owner of this saliva."

The technician said with a frown.

"How?"

Lin Yao walked over.

"The bacteria in his saliva are very high, and they don't look like a normal person anymore."

The technician explained.

"Wouldn't this murderer be a terminally ill person, so he pulled the deceased as a backdrop?"

Yao Jin immediately analyzed beside him.

"It's not just that you're not in good health!"

A technician who was operating the instrument next to him immediately said.

Everyone couldn't help but look at it.

Later, the technician said:

"From his salivary enzyme, there is no amylase detected at all, this is still human!"

"What does that mean?"

Yao Jin didn't know why, and asked suspiciously.

The technician next to him explained:

"Amylase is a biological enzyme in the human mouth that breaks down starch, which is generally found in the mouth of omnivores."

"And there is no saliva in it, which means that he usually doesn't eat starch? This is the rhythm of cultivating immortals!"

After listening to his explanation, Lin Yao and Yao Jin nodded slightly.

"It's not human!"

Yao Jin shook his head with a sigh and complained.

"yes. It's not a man, it's an animal."

Lin Yao nodded slightly on the side and said in a deep voice.

"Yes, it's a brute! The killing method is so cruel!"

Yao Jin immediately agreed.

"I mean cats!"

Lin Yao said directly.

"Huh? Cats?"

"Yes, don't forget, there's a white cat in the room."

Lin Yao's eyes suddenly looked at the few of them.

"Yes! This saliva could be a cat's!"

Yao Jin reacted suddenly, and suddenly couldn't laugh or cry!

"But. Why does the cat lick his phone screen?"

Immediately afterward, Yao Jin asked suspiciously.

The technician also said suddenly:

"If you say that, you can say it in the past."

"Because in addition to the saliva we found on the screen of the phone, we also found an insoluble substance, this ingredient. None of us have seen it before."

"I can't find a matching substance in the lab."

Lin Yao frowned, nodded slightly, and then said:

"Then this substance is likely to be a kind of cat food, which can lure cats to lick the screen."

"Yes! That makes sense!"

Yao Jin said with some excitement.

Immediately afterward, he couldn't help asking:

"But who lured the cat to lick the screen? And what is his purpose?"

Lin Yao pondered for a moment, and then said:

"Think about it, what is this phone for?"

"Calling? Send a post?"

Suddenly, Yao Jin's eyes widened and he asked in disbelief.

Then he said:

"Do you mean? Did the killer put that food on the screen to create a physical timed transmitter?"

"This kind of reasoning is indeed the most reasonable, but there are still some problems with the details of this, which need to be further studied."

Lin Yao nodded and said,

"Where is the cat now? Let's just get the cat over and test it."

"And then there's the saliva that gets it and tests it."

"The cat is now in Xiao Zhao's house, it's too noisy here, so I'll let him bring the cat over now."

One of the technicians said immediately, then pulled his phone out of his pocket.

"Okay, you guys test the cat first."

Lin Yao nodded, and then said to Yao Jin:

"Let's go, let's go to Bai Ling now to find out about the cat's situation."

"Okay."

After finishing speaking, Lin Yao and the two walked out directly.

Soon, they came to Bai Ling's parents' house again.

knocked on the door and entered, this time it was Bai Ling's father at home.

After Bai Ling's father saw Lin Yao and them, he was more emotional, and immediately said:

"Comrade policeman, come in quickly!"

"Oh, I really didn't expect this to happen."

"I didn't come back from the field in a hurry after the accident, I only got home last night."

After arranging Lin Yao and the two of them on the sofa, Bai Ling's father looked at them and said.

"Well, have you met your daughter's boyfriend Cao Jie before?"

Lin Yao stared at him tightly and asked him.

"Cao Jie. I've seen it!"

Bai Ling's father pondered for a moment, and then immediately nodded,

"He's been to the house a few times before, and I've cooked for them."

"What is your impression of him?"

Immediately after, Lin Yao continued to stare at him and asked.

"My impression of him. To be honest, it's good."

Bai Ling's father frowned slightly, then nodded and said,

"I feel that kid looks quite honest and good at getting things done, uncle long uncle short uncle."

"So after he came for the first time, I was quite happy with him and supported the two of them together."

"And I didn't know what the conflict he had with my daughter."

"Isn't it that day when I was working outside, and suddenly I heard Cao Jie's child rushing to my daughter's house, and I felt incredible."

"But before I could react from the shock, I suddenly heard the news of his death."

"It's incredible."

Bai Ling's father couldn't help but shake his head and sighed.

"Where do you work?"

After Lin Yao listened, he looked at him and asked.

"Heijo."

"Did you just come back yesterday?"

"Yes."

After finishing speaking, Bai Ling's father got up and walked to the cabinet next to him, then took a ticket, handed it to Lin Yao, and then said:

"Look, the ticket is still here."

Lin Yao glanced at it, then grinned slightly:

"I just asked casually, and I didn't suspect you, you don't have to show me the ticket."

"Oh, oh, I'm not afraid that you won't believe me."

Bai Ling's father smiled wryly and said.

Yao Jin's gaze was fixed on him.

"By the way, comrade policeman, is there something you are here for this time?"

Immediately after, Bai Ling's father hurriedly looked at Lin Yao and asked.

"We'd like to find out something about your daughter."

Lin Yao looked at the closed bedroom door inside and said.

"Oh, that's right, wait a minute, she's sleeping, I'll wake her up!"

After finishing speaking, Bai Ling's father quickly got up and shouted loudly into the bedroom:

"Lingling! Lingling! Hurry out and get out! Comrade police are looking for you!"

A moment later, Bai Ling walked out of the bedroom with sleepy eyes.

She looked at Lin Yao and the two of them, rubbed her eyes, and then said:

"How? Comrade policeman, has there been any progress in the case?"

"We're still investigating, this time

I'm here to find out more about you."

Lin Yao nodded slightly and said.

"If you know what's going on, tell me."

Bai Ling sat down on the sofa opposite Lin Yao and asked.
