Meng Yanchen looked at Fan Shengmei, his gaze firm yet gentle. "Xiaomei, believe me, everything will be alright. We will definitely find the mastermind and solve all the problems." Fan Shengmei nodded slightly, still worried, but Meng Yanchen's words gave her strength. However, what they didn't know was that a greater crisis was quietly approaching, and a storm was about to sweep in when they were least prepared.

Meng Yanchen knew all too well the uproar that would ensue if Fan Shengmei's fake socialite identity were exposed. He acted decisively, quickly arranging a series of stringent protection measures for her. He picked up the phone and spoke succinctly and forcefully into the receiver: "From now on, double Ms. Fan's security detail. Ensure her every move is under our surveillance, and that nothing goes wrong. Also, restrict some of her social activities in the near future; aside from essential company business, minimize her outings." A series of "Yes"s came from the other end of the line before Meng Yanchen hung up.

Seeing Meng Yanchen's concern for her, Fan Shengmei felt both touched and somewhat helpless. She understood Meng Yanchen's good intentions, knowing that her current situation was like a ticking time bomb. However, being used to her freedom, she couldn't help but feel worried about being suddenly restricted in her social activities. "Yanchen, isn't this too much trouble? Besides, I don't want to bring more burden to you and the company because of me," Fan Shengmei said softly, a hint of unease in her eyes.

Meng Yanchen walked to Fan Shengmei's side and gently took her hand. "Xiaomei, this is not a burden. Your safety is the most important thing. I can't let you be in any danger. The opponents we are facing now are ruthless, and only in this way can we protect you to the greatest extent." Meng Yanchen's eyes were full of concern and determination. Fan Shengmei felt the warmth from his palm, and her worries eased a little.

Meanwhile, Meng Yanchen did not stop his investigation into the mysterious investment group while protecting Fan Shengmei. He sat at his desk, various data and documents flashing on his computer screen. He stared intently at the screen, his eyes sharp, trying to find a breakthrough from this complex information. After some in-depth digging, he discovered that a vast network of interests seemed to be hidden behind the mysterious investment group, a complex network involving multiple industries and fields.

Meng Yanchen realized that to completely uncover the true nature of the mysterious investment group, he had to start from the periphery of this network of interests. He picked up a pen and drew a simple relationship diagram on a piece of paper, marking some known related companies and individuals. As he drew, he pondered and muttered to himself, "Starting from here, gradually delving deeper, I'm sure I'll find the key clues."

Watching Meng Yanchen's focused expression, Fan Shengmei felt a surge of admiration. She walked over to him and said, "Yanchen, let me help you. Although I might not be as professional as you, more people mean more strength." Meng Yanchen looked up at Fan Shengmei and smiled slightly, "Okay, with your help, things will definitely be much easier. Help me organize these documents and see if you can find any commonalities or anomalies." As he spoke, he handed Fan Shengmei a thick stack of documents.

Fan Shengmei took the documents and sat down on the sofa, carefully reviewing them. The office was extremely quiet, save for the sounds of papers turning and Meng Yanchen typing on his keyboard. Security personnel stood silently outside the door, vigilantly watching all movements around them.

As time went on, Meng Yanchen discovered that this network of interests was intricately connected to a number of seemingly unrelated small companies. These companies were scattered across different industries, small in scale, but played a crucial role at certain key junctures. He wrote down the names of these companies on a piece of paper, pondering the potential connections between them. "These small companies are likely pawns of a mysterious investment group, used to divert attention and funds," Meng Yanchen muttered to himself.

While sorting through the clues, Fan Shengmei also discovered some interesting developments. She found that several of the companies were registered around the same time and in very similar locations, and although their business scopes differed, they were all indirectly related to a large project. "Yanchen, look at these companies. Could they have some kind of cooperative relationship, or be controlled by the same force?" Fan Shengmei pointed out her findings to Meng Yanchen.

Meng Yanchen carefully examined what Fan Shengmei had pointed out, a glint of light flashing in his eyes. "You're right, Xiaomei. It seems we're one step closer to the truth. These companies may very well be hiding the core figures of a mysterious investment group. Let's continue our investigation and see if we can find more evidence."

In the following period, Meng Yanchen and Fan Shengmei devoted themselves entirely to organizing and analyzing the clues. They constantly discussed and speculated, trying to piece together the entire network of interests. Meng Yanchen also contacted some of his connections in the business world to inquire about the background and relevant information of these small companies.

However, as the investigation deepened, they discovered that this network of interests was far more complex than they had imagined. It involved various exchanges of benefits, backroom deals, and power struggles. Each clue, when explored further, revealed more mysteries. Meng Yanchen frowned, knowing that this battle would be exceptionally difficult.

Seeing Meng Yanchen's tired appearance, Fan Shengmei felt a pang of heartache. She got up and poured two cups of coffee, handing one to Meng Yanchen. "Yanchen, take a rest. Don't overwork yourself. We'll take it slowly; we'll find the truth eventually." Meng Yanchen took the coffee, took a sip, and looked at Fan Shengmei gratefully. "Thank you, Xiaomei. With you by my side, I feel full of motivation."

By now, dusk was falling, making the office lights appear exceptionally bright. The city outside was ablaze with lights and bustling with traffic, but Meng Yanchen and Fan Shengmei had no time to appreciate this vibrant night scene. They knew that beneath this calm surface, a fierce storm was brewing.

Meng Yanchen leaned back in his chair, rubbing his temples as he pondered his next move. He knew that to uncover the mysterious investment group's network of interests, he had to be even more cautious. A single misstep could alert them, giving his adversaries the opportunity to destroy evidence or transfer assets.

Fan Shengmei looked at Meng Yanchen, her heart filled with worry. She worried that her identity would affect Meng Yanchen's investigation, and even more so, she worried whether the protective measures would truly be effective in preventing her identity from being leaked. Once her identity was exposed, not only would she face enormous public pressure, but Meng Yanchen and the Fu Group would also be implicated.

Meng Yanchen seemed to understand Fan Shengmei's thoughts. He walked to her side and gently put his arm around her shoulder. "Xiaomei, don't worry. We've taken the strictest protective measures and won't let your identity be easily revealed. Moreover, our investigation is progressing steadily, and I believe we'll find a solution soon." Fan Shengmei nodded slightly, leaning against Meng Yanchen's chest, feeling his warmth and strength.

In this tense and challenging moment, Meng Yanchen and Fan Shengmei rely on each other to face the impending crisis. However, will Meng Yanchen be able to successfully uncover the mysterious investment group's network of interests? Will the protective measures be effective in preventing Fan Shengmei's identity from being exposed? Everything remains uncertain, like dark clouds hanging over their heads, ready to unleash a storm at any moment.
