Nominal: Hou Liangping blocking the door? He was slapped away!

A dial tone came through the microphone.

"Old Xu's office."

Shen Zhong read out the paper report, whiteboard photos, and wax seal file copies in sequence, speaking at a steady pace without any unnecessary pauses.

"A forged coordination letter was discovered on the northern route; the paper batch number is QC-7913."

"This batch number will be supplied to three offices within five years."

"After comparing the logistics roster, the location of the seal wax diagram left by Gao Yuliang was found to be the same, ultimately pointing to QC-01."

There was no immediate response on the other end of the phone.

Shen Zhong held the cigarette between his fingers, but didn't light it.

"The other party, under the guise of the forward coordination group, attempted to access the northern front's combat readiness data, involving military supply contracts, communication support and joint testing frequency bands, and combat readiness storage codes."

"The nature of this case has crossed the boundaries of a local case."

"I have initiated the first-level sealing, the original physical evidence is kept on the northern route, and the photo cards, test reports, and transfer records are put into the highest confidential chain."

Finally, an old man's voice came from the other side.

"Who touched the materials?"

"I am Zhou Weiguo, an inspection technician."

"Where are the technicians?"

"Physical isolation has been implemented."

"Where is Zhou Weiguo?"

"Outside the door."

There was a pause on the other end of the phone for a few seconds.

"Keep an eye on the northern front, and don't let the supply to Handong break down."

"Yes."

Shen Zhong put the microphone back, his hand still resting on the device.

There were two knocks on the door.

"Enter."

Zhou Weiguo pushed the door open and came in. His eyes first swept over the phone, then fell on Shen Zhong's hand.

"Chief?"

"The highest level of authority has been reported."

Zhou Weiguo's Adam's apple bobbed. "What did Old Xu say?"

"Keep an eye on the northern front, keep the eastern front open."

Zhou Weiguo immediately stood up straight. "Understood."

Shen Zhong put the cigarette back in the pack and his gaze fell on the photocopy on the table.

"That printer in the provincial department is about to spit something out."

……

Public Security Bureau of Handong Province.

The lights in the intranet center were on full blast, several rows of server racks were lit with green lights, and the fans were humming loudly.

Lu Yike was wearing a dark suit, her hair was neatly tied up, a temporary pass was hanging on her chest, and her cuffs were buttoned up tightly.

She walked at the front, followed by technical investigators, inspectors, forensic doctors, and two armed police officers.

The deputy commissioner of police inspectors was also in the group.

He was in his forties, wore frameless glasses, and carried a notebook. He usually spoke in a mild tone, but today he kept wiping his glasses with his hand.

"Director Lu, the printer room is part of the equipment maintenance area within the hall, and according to regulations, it must be registered first."

Lu Yike glanced at him.

"It's already registered."

"I haven't received the instructions."

Lin Huahua handed over a paper authorization document.

"It was signed by Director Qi, and the quarterly inspection and filing process is synchronized."

The deputy director took it, glanced at two lines, and his lips twitched slightly.

"The process went by quite quickly."

Lu Yike raised her hand.

Two police officers stepped forward and blocked the access control card reader at the entrance of the printer room.

Click.

The door opened.

Inside are three printers, two copy machines, and a separate maintenance terminal.

Lin Huahua put on gloves and bent down to pull out the thread.

"Physical external network disconnection."

The technician next to me labeled the network cable with its serial number, took a picture, and put it in a bag.

The deputy director frowned. "Isn't that a bit of an exaggeration? It's just a printer."

Lu Yike didn't turn around.

"It just sent out an order."

The deputy director's hand stopped on the record book.

Lin Huahua connected the maintenance terminal to the offline analysis device, and a series of logs scrolled onto the screen.

"The printer in the executive deputy director's office received a remote cache clearing command at 5:49 p.m. yesterday."

Lu Yike looked at the screen.

"account number."

"Chief Administrator of the Information Center"

The technician immediately added, "But the login profile is wrong, the password is correct, the token is correct, but the behavior doesn't match."

Lu Yike took half a step closer and said, "Explain yourself."

"The administrator usually uses the command line, which has a very short operation path. This time, he clicked on the graphical interface first and accidentally opened the port list twice."

Lin Huahua gave a cold laugh.

"Wearing someone else's shoes, yet still unable to walk."

The deputy director adjusted his glasses. "If the account was hacked, then we should go to the information center to arrest the culprit."

Lu Yike finally turned around to look at him.

"What's the rush?"

The deputy director looked somewhat embarrassed. "I was just pointing out the direction of the investigation."

"The direction is determined by the evidence."

Lin Huahua pressed Enter.

The screen switches to the second layer of logs.

"The springboard has been stripped away. The information center's general administrator account is just the first layer of the shell. The real command-issuing IP is maintained on the network within the hall."

The technician took a breath. "Director Lu, this node has very high permissions."

Lu Yike stared at the address.

"Belonging".

Lin Huahua pulled up the comparison table, her hand pausing for a moment.

Everyone inside the room could see it clearly.

Police Inspectorate.

Advanced maintenance node.

The record book in the deputy director's hand fell to the ground with a thud.

Someone turned to look at him.

He bent down to pick it up, his glasses slipped down to his nose, and it took him two tries to reach the notebook before he finally managed to pick it up.

Lu Yike looked at him.

"Deputy Director, why is your Inspection Department's maintenance node cached for the ghost case within the Provincial Department?"

The deputy director straightened his glasses, his face pale.

"This... I need to go back and verify this."

"Let's verify it right here."

"Director Lu, the Inspectorate has its own internal procedures."

Lu Yike lifted up the authorization document.

"The procedures that Director Qi gave me are sufficient."

Before the deputy director could speak, Lu Yike had already turned around.

"Group Two, follow me."

The footsteps in the corridor were hurried.

The Inspectorate Office is not far from the internal network center, separated only by a security door.

The deputy director walked behind, his pace slowing down.

Lin Huahua glanced at him.

"If you feel unwell, you can have the forensic doctor examine you first."

"I'm fine."

He tucked the notebook under his arm, but his hand reached into his pocket.

Lu Yike stopped in her tracks.

"Take your hand out."

The deputy director froze for a moment.

Two police officers stepped forward at the same time.

He raised his hand, his palm empty.

Lu Yike looked at him for two seconds, then said, "Keep walking."

A low humming sound came from the crack in the door to the deputy director's office.

It looks like a machine biting something.

Lu Yike raised her hand.

boom!

The police officer kicked the door open.

Paper scraps were scattered all over the office floor.

The shredder on the table was still turning, with black fragments piled up in the transparent box, and a few silver metal pieces stuck on the edge of the blades, making a clicking sound.
