I put you in charge of those rebellious female soldiers, how come they all became top special forces

There's nothing wrong with looking at your phone in itself; who doesn't use their phone while eating these days?

What's strange is the way he looks at his phone.

Every two or three minutes, this kid would pick up his phone, glance at it, and then put it back face down on the table.

After about ten seconds, he picked it up again to look at it.

Watch for a while, then close it.

And before each time he put it down, he would glance around.

Anran's chopsticks paused for a moment in the lunchbox.

She didn't say anything and continued eating with her head down, but her eyes kept glancing at Lu Chuan out of the corner of her eye.

Halfway through the meal, An Ran put down her chopsticks, picked up her lunchbox, and moved next to Chen Zheng.

Chen Zheng was drinking soup when he saw her coming closer, so he turned his head away.

An Ran lowered her voice and whispered a few words in his ear.

Chen Zheng paused in his soup-drinking motion, then asked in a low voice, "Which one?"

An Ran gestured in the direction with her eyes.

Chen Zheng picked up his bowl and, while drinking the soup, glanced over there out of the corner of his eye.

Lu Chuan had just placed his phone face down on the table, ate a couple of bites of rice, and then picked it up again a dozen seconds later.

Chen Zheng withdrew his gaze and asked, "How did you notice that?"

After a moment of contemplation, An Ran replied:

"If someone repeatedly performs a meaningless action, there's usually only one possibility: they're nervous."

"Nervous people will subconsciously repeat certain actions to relieve stress. The more consistent the frequency, the more deliberately they are suppressing their emotions."

Chen Zheng looked at her, his expression somewhat complicated.

An Ran felt a little uncomfortable under his gaze and subconsciously touched her nose.

"...Is there something wrong with what I said?"

Chen Zheng shook his head and simply said...

"good."

An Ran's ears turned red instantly.

But she couldn't quite suppress the smile from her lips.

She quickly picked up her lunchbox, returned to her seat, and continued eating.

At the next table, Keyboard looked at An Ran's smug face and sighed silently.

Li Yue leaned closer and whispered, "What's wrong?"

Keyboard shook its head, looking wistful.

"The instructor only said a few words, but it made Sister Anran so happy."

"If the instructor praised her a little more one day, wouldn't Anran practically ascend to heaven on the spot?"

Li Yue thought about it carefully, then nodded.

"Possibly."

That night.

Chen Zheng did not return to the guesthouse.

He stayed in the lab, with several reports spread out on the table, but he didn't even look at them. He sat in a chair, closing his eyes to rest.

The keyboard was pushed into the server room, and more than a dozen monitoring windows were open on the laptop screen at the same time.

As per Chen Zheng's request, Qin Hong increased the night patrols, with a group of people passing by Building No. 3 every fifteen minutes.

An Ran didn't leave either.

She moved a chair to the corner of the lab and sat down.

Chen Zheng opened his eyes and glanced at her.

An Ran said expressionlessly, "I'll keep watch for you."

Chen Zheng remained noncommittal and closed his eyes again.

Time passed second by second.

11 o'clock.

Twelve o'clock.

One o'clock in the morning.

The keyboard tracking system suddenly lit up.

The keyboard sprang up from the chair, and a window suddenly popped up on the computer screen.

[MAC address - captured.]

She quickly opened another window and compared the captured hardware fingerprint with the equipment registration database on the institute's intranet.

The match was generated quickly.

The hardware fingerprint of the access terminal closely matches the characteristics of a registered laptop computer on the research institute's intranet.

The registered user of that laptop was Lu Chuan.

The keyboard took a deep breath, its fingers continuing to press down.

Just as she was about to report her conclusions to Chen Zheng, another set of data popped up on the screen, leaving her finger hovering in mid-air.

The hardware fingerprint sensor on this laptop works perfectly and is identical to Lu Chuan's machine.

However, the MAC address used to connect to the intranet is incorrect.

On the surface, this MAC address is exactly the same as the physical address of Lu Chuan's laptop network card.

However, during the deep validation of the keyboard, a hidden anomaly was discovered.

The response time for this MAC address is a little slow.

In other words, this MAC address was spoofed.

The real physical machines are not in research institutes.

It remotely bridged into the intranet through an external device and operated it disguised as Lu Chuan's laptop.

The fingers returned to the keyboard, beginning to track the physical location of the external bridge point.

Fifteen minutes later, she pushed open the laboratory door with her laptop in her arms.

Chen Zheng had already opened his eyes and was looking at her.

An Ran turned her head as well, but did not speak.

The keyboard walked up to Chen Zheng, turned on the screen, and pondered how to report.

"Someone took the bait. At 1:03 a.m., a terminal opened the fake report."

"The hardware fingerprint sensor matched Lu Chuan's laptop."

"But it's not actually Lu Chuan's computer operating it."

"The MAC address is spoofed; the other party remotely bridged in through an external device."

"Someone outside the research institute used a device that cloned the hardware fingerprint of Lu Chuan's laptop to access the internal network."

Chen Zheng's eyes turned cold.

Where is Lu Chuan himself?

"Two possibilities." Keyboard took a deep breath and held up a finger. "First, Lu Chuan is innocent."

"His computer was physically touched at some point, and the hardware information was taken away."

"This operation is not difficult and can be done in three to five minutes. Lu Chuan himself probably has no idea about it."

She paused for a moment, then raised her second finger.

"The second possibility is that Lu Chuan himself is the mole."

"He deliberately used a remote bridging method to operate, so that if he were exposed, he could say that he was framed."

Chen Zheng was silent for a moment, then asked, "Has the location of the external bridging equipment been locked?"

"Half locked." The keyboard pointed to a flashing dot on the screen. "The signal characteristics point to the northeast of the research institute, about two kilometers away, but we don't know which building it is exactly."

Chen Zheng nodded, said nothing more, and leaned back in his chair.

An Ran sat quietly to the side and listened without interrupting.

After Keyboard finished explaining the situation, they returned to the computer room, where only the two of them remained in the lab.

An Ran looked at Chen Zheng and asked in a low voice.

Is it serious?

Chen Zheng shrugged.

"It's not certain yet, but it's definitely not simple."

An Ran nodded and didn't ask any more questions.

She took a white plastic bag out of her bag and placed it in front of Chen Zheng.

Inside were two steamed buns and a cup of soy milk, just like last night.

"Eat and get back to work. I'll stay here with you."

Chen Zheng didn't reply, but simply reached out, picked up the bun, and took a bite.

Anran leaned back in her chair, crossed her arms, and stared down the corridor.

This posture is exactly the same as in the training field.

Serious, focused, and meticulous.

Chen Zheng chewed on his steamed bun, glancing at the red mark on her ear out of the corner of his eye. He couldn't help but shake his head slightly, but didn't say anything.
