Sheriff Uncle, open the door quickly! I've come to solve a case!

"We just received a report that another body has been found!"

Upon hearing this, Qin Qingzhou immediately got up, abandoning all sleep.

Bai Zhizhi had just fallen asleep, and he didn't intend to wake him. He simply left home.

The person who reported the incident was a woman who had just finished her night shift. She was terrified and was trembling in the back seat of the police car.

"The identity of the deceased is still under investigation. The person who reported the incident was a woman who had just finished get off work at the factory and was on her way home when she heard a scream while passing through this alley. However, she was too scared to continue and ran home first."

"Two hours later, I felt something was wrong and went out to check. I saw the body parts scattered all over the ground being eaten by the stray dogs in the neighborhood."

It's still dark, and the whole path is shrouded in mist. You can vaguely see bloodstains on the stone path.

"The method is extremely similar to that of the previous killer. We suspect that the killer tried to put the body parts into plastic bags and throw them into the river, but was discovered by this woman halfway through, so they had no choice but to temporarily dump them here."

The survey team suddenly spotted something and shouted, "Team Leader Qin! We've found footprints here!"

Qin Qingzhou immediately got out of the car.

There was indeed a footprint next to the bloodstain, and judging by its size, it belonged to a man.

The incident happened suddenly, and the perpetrator had no time to clean up the scene.

They've given themselves away.

Qin Qingzhou immediately turned and walked towards the security room: "People from the data department, come with me to check the surveillance footage!"

But the forensic doctor called out to him at that moment, "Wait!"

Qin Qingzhou stopped in her tracks as the forensic doctor approached with a small bag of minced meat.

"Captain Qin, something's wrong with this piece of minced meat."

"explain."

"The edges of this piece of flesh have obvious bite marks, but based on our comparison with the mouth shape of a stray dog, the marks are relatively wide and the teeth are shallow, so we conclude..."

"It was the bite from the assailant."

"vomit!"

Li Ku had been holding back for a long time, but when he heard this, he couldn't hold it in anymore and started vomiting while clutching his stomach.

"But this is also good news, as we can see if we can detect the killer's saliva through this crack."

Qin Qingzhou's expression changed slightly, but she quickly became serious: "It's up to you to test it."

After the forensic doctor left, Qin Qingzhou breathed a sigh of relief.

The numerous clues left at the scene undoubtedly propelled their investigation forward.

But why was the usually meticulous killer so careless this time?

What exactly is he up to?

Upon arriving at the monitoring room, the data team had already copied the surveillance footage from the time of the incident.

In the surveillance footage, the swaying deceased was walking along the path, with a man whose face was not clearly visible about five meters behind him.

It was too dark, and the whole picture was blurry.

The man appeared to be around 170-175 cm tall, and his walking posture was quite strange.

This was the first time the police had seen the killer's outline. Qin Qingzhou recalled all the suspects, and none of them walked like that.

Then, five seconds later, the man's shadow, like a cheetah in the night, rushed toward the dead man.

He possessed superhuman strength; facing a 160-pound corpse, he simply lifted it into the air. The corpse struggled a few times, then became still.

"Holy crap..."

Li Ku watched from the side, frowning, and couldn't help but curse under his breath.

The scene that followed was even more gruesome, and Qin Qingzhou remained silent for a long time after watching it.

……

As soon as they returned to the police station, Bai Zhizhi ran over crying and hugged his leg.

"Uncle, you're so mean! Where did you go?! Zhizhi woke up and didn't see you, I was so worried!"

Qin Qingzhou contacted Lin Yuhe before leaving the house, asking her to bring the little one to the police station.

The little one was wearing a new bunny dress bought yesterday; she looked incredibly cute and soft, with her little face all wrinkled up.

Qin Qingzhou had important business to attend to, so he dragged Bai Zhizhi, who was limping, to the office, saying, "I have work to do, don't disturb me."

Bai Zhizhi was furious and bit Qin Qingzhou's leg, leaving a trail of drool on his trouser leg: "Uncle is bad!"

"Yes, I'm naughty, go play somewhere else. After I finish work, I'll take you to eat at Baiyun."

Bai Zhizhi immediately let go: "Bai Yun?"

"Um."

"I won't bother my uncle while he's working, hehe!"

Li Ku was dumbfounded. His Captain Qin had become a skilled babysitter so quickly, with a whole set of tricks for coaxing the baby.

Bai Zhizhi, who watches cartoons, has no idea what the world is like.

The group didn't try to hide anything from Bai Zhizhi and started discussing it right there in front of the whiteboard.

The discovery of a clue should have made everyone happy, but the expressions on these people's faces were increasingly grim.

Li Ku: "I always felt that he deliberately left clues for us."

Zhao Tai didn't understand: "Then what was his purpose in doing this?"

Qin Qingzhou was silent for a moment before saying, "Provocation."

"Or perhaps, something compels him to appear."

As for what it was, they had no way of knowing.

Two hours later, Hu Siqi came to them with the test report.

Hu Siqi slammed the report on the table, but remained silent for a long time.

Qin Qingzhou silently took the report, and after reading it, her mood plummeted.

Li Ku glanced at him and asked, "W-what's wrong?"

"Let me clarify first, it is absolutely not that we detected the problem."

"The test report showed that there was no saliva residue in the gnawed body part, but we found fingertip tissue residue in the same body part, and the DNA came from the victim in the third case."

The group was stunned.

"Furthermore, we also found skin tissue residue within the victim's fingernail remains, and the DNA from this... came from the victim in the fourth case..."

"That can't be..."

Even if Hu Siqi herself had tested positive, she wouldn't believe it, let alone if they didn't.

The previous four victims had their limbs removed, but this time, the victim's head was removed.

Qin Qingzhou's gaze slowly fell on a stack of photos on the table.

"puzzle."

Li Ku looked over in confusion: "What?"

"According to the surveillance footage, the murderer lifted the victim with his left hand. The victim struggled and grabbed the murderer's left hand, which happened to be the missing limb of the victim in the fourth case."

"The killer is slowly piecing together a human shape; only the torso is missing."

They have consistently ignored what Bai Zhizhi said.

Qin Qingzhou then looked at Bai Zhizhi, who was watching cartoons on the sofa: "Perhaps Zhizhi is right, this is a piece of the puzzle."

Li Ku refused to believe it, saying, "That's impossible. Captain Qin, you've become like this after spending so much time with Zhizhi."

Hu Siqi nodded: "Yes, even if it's a jigsaw puzzle as you say, it's impossible for it to move just by piecing together all the limbs. It's not human at all!"

Bai Zhizhi was engrossed in the Paw Patrol's story of rescuing the little yellow cat.

A shadowy figure loomed down and took the tablet.

"Ah, little yellow cat!" Upon seeing Qin Qingzhou, Bai Zhizhi immediately beamed, "What's wrong, Uncle? Zhizhi is very well-behaved and didn't disturb Uncle's work!"

Qin Qingzhou spoke with great reluctance.

"...I need your help with something."
