You went on a blind date and presented an A-level wanted criminal as a meeting gift?

"Buzz—"

A black, bulletproof SUV roared and sped off like an arrow along the western suburbs highway, heading straight for the IFC in the city center.

Lin Chen's face was calm as water, but the knuckles of his hands gripping the steering wheel were slightly white from the force.

Zhao Na!

Ye Qingcheng's personal secretary, a woman who has been with her for five years and whom she treats almost like a younger sister.

Very suspicious!

Lin Chen sneered inwardly and floored the accelerator.

When he rushed back to his president's office on the top floor of the IFC, Ye Qingcheng was frantically directing the group's top IT security team to conduct a thorough investigation of the entire building's network.

"How's it going? Are there any anomalies in the firewall logs?"

Ye Qingcheng's voice was cold and urgent.

"Reporting to General Manager Ye, no! Between 2 AM and 3 AM last night, all server data streams were normal, with no large outbound transmissions recorded! The firewall was impenetrable; not a single attack alert was triggered!"

A man who looked like a technical supervisor wiped the cold sweat from his forehead as he reported to his supervisor.

"Where's the CCTV footage? Check the CCTV footage!"

"We checked it too! We watched the surveillance footage from Dr. Li's office and the entire floor more than a dozen times. Apart from the regular cleaning staff, no suspicious persons entered or left! Moreover, Dr. Li left alone, and his expression was normal; there was nothing unusual about him!"

A series of "no abnormalities" made the atmosphere in the office extremely oppressive.

Ye Qingcheng's heart sank to the bottom.

The fact that no trace could be found meant that the other party's methods were beyond her comprehension.

This was the first time she felt a sense of powerlessness towards the business empire she had built with her own hands.

Just then, the office door was pushed open, and Lin Chen walked in.

"Let them all go out."

Lin Chen's tone was very calm.

"Honey? What are you doing over there...?"

Upon seeing Lin Chen, Ye Qingcheng felt as if she had found her pillar of support and immediately went to greet him.

"nailed it."

Lin Chen gave her a reassuring smile, then walked straight to the queen's large desk and plopped down on it.

He didn't even glance at those so-called IT elites, but simply leaned back lazily in the leather boss's chair, crossed his legs and propped them up on the table, looking completely nonchalant.

"Qingcheng, give your elite team a break."

"Checking surveillance footage and firewall logs? That's what the police do, and the lowest level of that."

Lin Chen's words made the faces of the IT executives turn red and white, but they dared not refute him.

"Honey, have you discovered something?"

Ye Qingcheng was incredibly clever and immediately realized what was happening. She waved her hand, signaling everyone to leave.

Once again, only the two of them remained in the office.

"The mole is Zhao Na," Lin Chen said bluntly.

"What?!"

Even with Ye Qingcheng's strong mental fortitude, hearing this name was like being struck by lightning, and her pretty face instantly turned deathly pale.

"Impossible! Absolutely impossible! Nana, she..."

"Nothing is impossible."

Lin Chen interrupted her, his eyes sharpening.

"What Li Feng said himself was his last memory before his mental breakdown."

Ye Qingcheng staggered back two steps and leaned against the desk to barely steady herself.

Being betrayed by her most trusted confidant was a blow far more unbearable for her than the loss of the data itself.

Lin Chen didn't rush to comfort her, because he knew that when dealing with a woman like Ye Qingcheng, presenting irrefutable evidence was more effective than any comforting words.

He turned around in the boss's chair to face the computer that Ye Qingcheng used exclusively and had the highest access privileges to.

[God-level hacking skills]!

[Mastered by a top-tier actuary!]

Two god-level skills activated simultaneously!

Lin Chen's hands moved across the keyboard, creating a dazzling display of afterimages.

On the screen, a waterfall of data was scrolling wildly at a speed that exceeded the limits of human vision!

"Honey, what...what are you doing? They've already checked my blog, there really isn't anything..."

Ye Qingcheng asked, puzzled.

"Who said I was going to check the internet?"

Lin Chen didn't turn his head, a knowing smile curving his lips.

"I'm checking the air conditioner."

"Check...check the air conditioner?"

Ye Qingcheng was completely stunned. She felt that her thoughts could no longer keep up with this man's pace.

"That's right."

Lin Chen explained leisurely as he typed on the keyboard.

"People who can set up such a scheme must have excellent hacking skills. Since they dared to do it, they must have cleaned up all traces on the network."

"Going down this road leads to a dead end."

"However, they overlooked one point."

Lin Chen pressed the Enter key heavily, and the data stream on the screen stopped instantly. In its place was an extremely complex 3D structural diagram of the "Intelligent Central Air Conditioning Temperature Control System" of the IFC building, which was covered with countless sensor nodes.

"When a person is under extreme tension, excited, or engaged in activities that require a high degree of concentration, such as transmitting secret data, their adrenaline surges, their metabolism speeds up, and their body temperature rises slightly without their knowledge, resulting in extremely subtle changes in the ambient temperature within a small area around their body."

"And the temperature control system for this building was designed by me. Its sensitivity can be accurate to 0.1 degrees."

"If any area experiences abnormal temperature fluctuations, the system will automatically adjust the airflow and fan speed in that area to maintain a constant temperature."

"These adjustment records, though small, will be faithfully recorded like tree rings in the lowest level log of the central air conditioning system."

"This thing is way more reliable than any weblog!"

As Lin Chen explained, Ye Qingcheng's beautiful phoenix eyes widened, until they were completely filled with emotions of "shock" and "admiration".

By tracking minute changes in human body temperature, the system traces the central air conditioning system's logs to pinpoint the suspect's location...

What kind of ingenious brain circuitry is this?!

In those few seconds of shock, Lin Chen had already completed all the calculations.

Less than three minutes later, his finger stopped and precisely pointed out an abnormal data node flashing red on the three-dimensional structure diagram.

"Found it."

Lin Chen turned his chair around, looked at Ye Qingcheng who was already too shocked to speak, and a playful smile appeared on his lips.

"From 2:0.5 AM to 2:15 AM last night, the ambient temperature in the secretary's office outside the president's office was a full 0.5 degrees Celsius higher than the daily average. To compensate for this 0.5-degree difference, the system automatically increased the airflow in that area by 15%."

He paused, his gaze fixed intently on Ye Qingcheng, and asked, enunciating each word clearly:

"Qingcheng, was your personal secretary, Zhao Na, working overtime here last night?"
