After the substitution marriage, I became the CEO's white moonlight

There was a gentle knock on the study door, and Gu Jinyan walked in with a cup of hot milk. Seeing Su Li frowning slightly with a hint of worry in her eyes, he asked softly, "What's wrong? Are you still worried about the company's affairs?"

Su Li raised her head, shook her head gently, nodded, and hesitated to speak. Gu Jinyan walked to her side, handed her the milk, and said softly: "If you have anything to say, just tell me, we will solve it together."

Su Li hesitated for a moment, but still handed the report in her hand to Gu Jinyan, pointing to the expenditure details of the R&D department and said, "Look, aren't the expenses in the past few months too high? I always feel like something is wrong."

Gu Jinyan took the report and looked at it carefully, frowning slightly. He pondered for a moment and asked, "Do you suspect that someone in the R&D department is cooking the books?"

"I just think something is fishy. We need to investigate further." Su Li analyzed calmly, "The R&D department's spending has always been high, but it has clearly exceeded the normal range in recent months, and..." She paused, her eyes sharpened, "I noticed that the whereabouts of several of the funds are suspicious."

Gu Jinyan nodded in agreement. He said in a deep voice, "I will investigate this matter myself, you don't have to worry."

Su Li shook her head and said firmly: "I want to check it with you too."

Gu Jinyan looked at her determined eyes and felt a warm feeling in his heart. He knew that Su Li was not the kind of weak woman who would hide behind a man when encountering problems. She had her own ideas and abilities.

"Okay, let's investigate together." Gu Jinyan held Su Li's hand, his eyes gleaming with determination, "This matter is of great importance, we must investigate it thoroughly."

The two began to act separately. Su Li carefully checked every expenditure of the R&D department, trying to find clues from it. Gu Jinyan began to investigate the employees of the R&D department, especially those who had behaved abnormally recently.

Soon, a researcher named Zhang Qiang caught their attention. Zhang Qiang was a veteran employee of the company with strong technical skills, but he had been taking leave frequently recently, and his work status was not as good as before. He was often absent-minded and even made phone calls secretly during work hours.

"Has Zhang Qiang behaved abnormally recently?" Gu Jinyan asked the head of the R&D department.

"Engineer Zhang, something seems to have happened at home recently, and he is in a bad mood." The R&D director stammered, "But don't worry, there is no problem with his work ability."

Gu Jinyan and Su Li exchanged glances. They both felt that the R&D director seemed to be hiding something.

"It seems that we have to make a breakthrough from Zhang Qiang..." Gu Jinyan said in a low voice, with a gleam in his eyes.

Gu Jinyan decided to invite his good friend, an experienced security expert, to join the investigation team. This expert is low-key and highly skilled, and has assisted the police in cracking many cybercrime cases. After he arrived at the company, he immediately conducted a comprehensive and detailed inspection of the company's network system.

"The firewall was tampered with, and some of the data transmission records were deliberately cleared." The security expert pointed at the code displayed on the computer screen, frowning, "Someone is trying to cover their tracks."

Gu Jinyan and Su Li looked at each other, their doubts deepening. The security experts' findings confirmed their suspicions that there were indeed problems within the company, and it was likely an act of corporate espionage.

"Can we find out who did it?" Su Li asked anxiously.

The security expert shook his head. "The other party's methods are very professional and cautious. They haven't left many clues yet. But..." He paused and pointed to an IP address on the screen and said, "This address is very suspicious. I will try my best to track its source."

At the same time, Gu Jinyan found R&D staff member Zhang Qiang and questioned him individually. Facing Gu Jinyan's sharp eyes and aggressive questions, Zhang Qiang was obviously nervous, his eyes flickered, and he began to stammer when speaking.

"Have you been in frequent contact with people outside the company recently?" Gu Jinyan asked, his tone calm but with unquestionable majesty.

"No...no, Mr. Gu, did you...did you misunderstand something?" Zhang Qiang stuttered, with beads of sweat oozing from his forehead.

"I advise you to tell the truth." Gu Jinyan's tone became stern. "We have some evidence. If you confess now, maybe you can get leniency."

Zhang Qiang's face turned pale, his lips trembled, but he still didn't say anything valuable. His eyes were erratic, as if he was struggling with something.

"It seems that you won't cry until you see the coffin." Gu Jinyan said coldly, standing up and preparing to leave.

At this moment, Zhang Qiang's cell phone suddenly rang. He answered the call hurriedly as if he had grabbed a life-saving straw.

"Hello?...What?...Okay...I understand..." Zhang Qiang's voice trembled and his face became more and more uglier.

After hanging up the phone, Zhang Qiang seemed to have lost all his strength. He slumped in the chair, his eyes empty, and muttered something to himself.

Gu Jinyan and Su Li looked at each other, and both had an ominous premonition in their hearts. They realized that things might be more complicated than they thought...

"He...he asked me to..." Zhang Qiang suddenly raised his head, his eyes full of fear, as if he had seen something terrible. However, before he could finish his words, he was covered by his mouth and forcibly dragged into the room at the end of the corridor. In the dim room, the spy leader hung up the call with Zhang Qiang, and a hint of viciousness flashed in his eyes. He had originally been confident that everything was under control, but he did not expect Gu Jinyan to invite such a powerful security expert.

"It seems that I underestimated them." He said to himself, with a hint of annoyance in his tone, but it was soon replaced by a deeper chill, "But the game has just begun."

He quickly turned on the computer, his fingertips quickly tapping on the keyboard, lines of code pouring down like a waterfall. He had to divert attention and create more chaos before he was completely exposed, buying himself more time.

At the same time, Gu Jinyan and Su Li learned from the panicked R&D staff that Zhang Qiang was forcibly taken away, and they felt even more uneasy. They realized that the spy network within the company might be larger than they thought, and what they were exposed to now might just be the tip of the iceberg.

"It seems that we have to start from other aspects." Gu Jinyan said in a deep voice, his eyes sweeping across the company's internal network structure diagram, trying to find a new breakthrough.

"Wait," Su Li suddenly seemed to remember something. She turned to the silent security director and asked, "You said before that the company's last security system upgrade was half a year ago, right?"

"That's right, Miss Su has a very good memory." The security director replied nonchalantly, completely unaware of how important a piece of information his words revealed.

Su Li and Gu Jinyan looked at each other, and both saw shock and disbelief in each other's eyes. Half a year ago, when Su Li had just joined the company, the person in charge of the security system upgrade project was...

At this moment, a shrill alarm suddenly rang throughout the company, and a bright red warning message popped up on the computer screen. The company's internal network was attacked and core technical data was being stolen rapidly.

Gu Jinyan's face turned pale, and he stood up suddenly, with a fierce look in his eyes: "We must not let them succeed!"
