"Sirens blare again!"

"Officer No. 0!"

"Officer Guan, welcome back to the team!"

Hua'an City.

Hongcheng Branch.

Office of the Second Squadron, Second Group.

Guan Feng leaned back in his chair, gazing at the slightly yellowed, old badge in his hand, his thoughts drifting back to three days ago...

Twenty years ago.

A serial killer suddenly appeared on a rainy night, committing seven crimes in half a month, putting the entire old city on edge.

Guan Lidong, the father, was appointed to a critical mission but died in the line of duty.

Three days ago.

Due to an unexpected accident, he was transferred from southern Yunnan back to Hua'an, where he inherited the police badge from his father at the commissioning ceremony.

"Father, I will find the murderer from back then and bring him to justice! I will avenge you!"

Seeing the object reminded Guan Feng of the person he had met. He solemnly put his police badge on his left chest and gave a standard military salute to the full-length mirror.

Abruptly.

A system notification sounded.

[Congratulations, host, on activating this futuristic police siren, Officer No. 0.]

[As long as the host solves cases, discovers important clues, and arrests criminals, they can obtain various superpower rewards. The rewards increase with the severity of the case, and specific rewards include basic attributes, criminal investigation skills, cutting-edge technology products, and future technologies!]

Guan Feng's expression froze.

Is this... a system update?

Before he could calm down, another voice came into his mind.

[A newbie gift pack is being distributed to the host! Do you wish to claim it?]

Claim it now!

Guan Feng responded in his mind.

[Congratulations, host! You have received a newbie gift pack!]

[Skill: Footprint Identification.]

[Level: High (Provincial Level)]

[Function: Based on footprints and other traces at the crime scene, it can determine the suspect's height, weight, gait, and other physical characteristics, assisting in case investigation.]

A notification sound was heard.

Like a high monk bestowing a blessing, a wealth of knowledge flooded into my mind, specifically knowledge about footprint identification.

A moment later.

Guan Feng opened his eyes after receiving the message, his gaze clearer than ever before.

"I never imagined that such a profound criminal investigation skill could be mastered in such a short time. No wonder he's a police officer from the future!"

Guan Feng was somewhat incredulous, and even more so, he felt an irresistible urge to test it.

Knock knock knock!

A knock on the door pulled him back to reality.

The office door was opened.

Squad leader Zheng Yuandong walked in with a sullen face, carrying a thermos.

The two groups of people sat up straight.

As the leader of the second group, Guan Feng naturally had the responsibility to step forward and ask, "Team Leader Zheng, has a case arrived?"

Zheng Yuandong nodded and said in a serious tone, "Just this morning! The local police station received a report that a dismembered body was found in the bushes by the lake in Chengnan Park, which is highly similar to the rape and murder case three days ago!"

"Preliminary analysis suggests that it may have been the same group of people who committed the crime! At the same time, the murderer's modus operandi is very similar to that of the rainy night murder case twenty years ago."

"The bureau is preparing to set up a special task force. Everyone, please put aside your current work and join us!"

"yes!"

The group accepted the order.

They all went downstairs to the crime scene.

......

On the bus.

Guan Feng gave a brief briefing on the case.

The incident occurred at Chengnan Park, which connects to an outer lake and has flowing water, making it an excellent fishing spot. This morning, two anglers went to fish in the pond and unexpectedly discovered the dismembered body.

Sitting in the passenger seat, Li Xiangdong, who is 1.9 meters tall, turned around with a slightly hunched posture and asked, "Team leader, can we rule out the two people who reported the case as suspects?"

Guan Feng nodded and said, "I have already asked Captain Zheng about this. Considering the special circumstances of the case, the bureau immediately investigated the two complainants as soon as they received the report. They did not have time to commit the crime."

Li Xiangdong said, "That's good!"

Guan Feng continued his report on the case, saying, "Currently, it appears the suspect most likely..."

Ten minutes later.

Police cars sped into the scene with sirens blaring.

Police officers on duty nearby rushed over immediately.

Guan Feng frowned, looked around, and asked, "Why are these people still here?"

The team member in charge of the blockade said with a wry smile, "Team leader! These fishermen have nothing better to do than watch the excitement. We had to chase them away several times before they were willing to move away."

Guan Feng reminded them, "Have you not yet grasped the importance of this case? This is the second one in three days, and it may even be related to that unsolved case from twenty years ago. Any oversight could make the case even more complicated."

The officer quickly explained, "Team leader, I just wanted to complete the formalities so that it would be more legitimate."

Guan Feng's expression softened slightly upon hearing this, but he waved his hand and said, "No need! First, put up the police tape at the entrance and temporarily close the entire park. Tell those who are watching the show that watching is fine, but anyone who makes a fuss and interferes with the investigation, no matter who is involved, will be thoroughly investigated!"

The officer immediately nodded: "Okay."

He called for reinforcements to expand the cordon.

Guan Feng then turned to Li Xiangdong and the others and said, "Investigate the scene first!"

"yes!"

There was this little incident.

Everyone knew that the situation was extraordinary, so they all became extremely vigilant, put on shoe covers and gloves, and stepped inside after lifting the cordon.

The shallow lakeside grass and lush green shrubs were about half a person tall.

As the sun rose, summer dew still clung to the ground, and not far away, a mangled corpse lay there.

Guan Feng asked, "Captain Chen, have you found anything?"

Chen Xuewen, a technician who was conducting the tests, pointed to the marks on the ground and sighed, "The suspect is very cautious and has a strong sense of counter-surveillance! So far, we have only found a few footprints of varying depths by the lake, which we are currently securing and preserving."

Guan Feng immediately squatted down and asked, "Is this all there is?"

Chen Xuewen reminded him, "There are still a few footprints over there that haven't been collected."

Guan Feng nodded and then asked, "Has the victim's body been examined? Is it consistent with what it was three days ago?"

Chen Xuewen pushed up his gold-rimmed glasses and stated his assessment: "There are signs of binding on the wrists, and nylon rope components have been extracted and are currently being tested. At the same time, the genitals have been severely cut, and the face has signs of burning and damage."

"Judging from the methods alone, it can't be said to be similar to the case three days ago, but it's almost the same! As for the case from twenty years ago, we still need to review the case files for detailed comparison!"

Guan Feng's brows immediately furrowed into a deep frown.

Three days ago!

A murder has occurred in the north of the city.

Team leader Zheng led an investigation team, but so far they haven't found a single clue.

The two cases may now be the work of the same group of people.

A chain reaction?

This possibility alone is enough to escalate this case.

Guan Feng instructed his team to conduct door-to-door investigations.

He squatted on the ground, his gaze fixed on the footprints, and a panel silently opened in his mind.

Footprint identification!

Will it actually work?
