The female receptionist was taken aback, then looked at Nan Yu with some confusion: "Other investigators? They haven't been here. Sirs, you are the first investigation team. Is something wrong?"

Nan Yu shook his head: "It's nothing."

Just then, Lu Ning asked, "You said the first investigation team? Were there any other teams that investigated before? For example, which high-ranking officials from the Federation?"

The female receptionist paused, then asked, "I don't know what this officer means?"

The female receptionist didn't understand, but Nan Yu and his group realized what was going on.

Their expressions fluctuated, and even a few of them momentarily lost their breathing rhythm, but they quickly calmed down.

Lu Ning calmly asked, "Has Saint Qinglan ever been here?"

The female receptionist exclaimed in surprise, "Saint Qinglan? Isn't that a top figure in the Federation? Why would he come to a small base city like ours? I don't know him! He might have been here before, but I probably wouldn't have known?"

The others exchanged glances, and Lu Ning calmly nodded: "Mm."

The female receptionist glanced at the group somewhat nervously, then said nothing more.

Soon, the elevator arrived at the top floor.

The female receptionist led the group to the director's office door and knocked.

Soon the office door opened, and a pretty woman stepped in.

The female receptionist bowed and said, "Secretary Wang, these officers are members of an investigation team from the Fog Bureau, and they wish to see the director."

Wang Bingxin glanced at the group and smiled, "Please come in, everyone. The director happens to have some time now."

As the group entered the office, they saw a middle-aged man sitting behind his desk reading a book.

The man had a refined and scholarly air, and was quite handsome.

After everyone entered, he put down his book, stood up to greet them, and said, "Welcome everyone. I didn't expect headquarters to remember this place. I wonder if anyone has brought their identification? It's just a routine check; I hope you can understand."

Nan Yu nodded and handed over the documents.

The bureau chief glanced at him and smiled, "Commander Nan, hello, hello. I'm Li Fu, you can just call me Lao Li. Please have a seat."

Li Fu pulled the group to sit down and then asked his secretary to make tea.

Nan Yu sat down, looked at Li Fu, and smiled, "Old Li, I'll get straight to the point. Our investigation team went missing here before, did you see them?"

As expected, Li Fu shook his head: "Never seen it."

Nan Yu raised an eyebrow and asked, "Have you ever seen Saint Qinglan?"

Li Fu was taken aback and exclaimed in surprise, "Saint Qinglan? Isn't that a top figure in the Federation? Why would he come to a small base city like ours? I don't know him. He might have come before, but I probably wouldn't have known."
