There was no elevator in the office building, so Qi Ran led Mu Tang up the stairs.

Mu Tang said to him, "When I walked to the door at noon, I saw Director Zhou going downstairs and had already walked here. ”

stopped at the staircase on the first floor, and her voice was lowered by two minutes, "Then I just called him and wanted to step forward, Yueyue fell downstairs......"

Qi Ran frowned, "You want to say that the murderer did it when he saw you walking here?" ”

Mu Tang looked around, there were few people in the office building at night, it seemed empty, and the sound of talking and going upstairs seemed to echo.

As she walked up the stairs, she lowered her voice and said, "I think maybe he's right next to me, watching me all the time." ”

In fact, this is what makes her feel most uneasy, the fear of being watched at all times.

Qi Ran's eyes were deep when he heard this, and he only said, "Don't think nonsense." ”

If there was really someone around her, the people of Xuanying would not know about it.

Thinking about it, he added, "Maybe he was on the roof at the time and saw you coming." ”

"But it's still very strange, he faked my mobile phone number to send a message to Yueyue in the last class, but I was still in the guard room at that time, how did he know that I would come to the office building?"

While speaking, the two of them had already walked to the third floor.

Mu Tang walked more and more slowly, pondering, "The first possibility is that he was also near the guard room at the time and heard me talking to Director Zhou. The second possibility, Director Zhou and Uncle Janitor, one is related to the murderer. ”

And these two may be all that Mu Tang can think of now.

In fact, the first one is unlikely, because the vicinity of the guard room is very empty, and there is no one else at the time, which Mu Tang is very sure of.

Well, there's only the second possibility.

So Uncle Janissor and Director Zhou, who is the most suspicious?

She is actually more inclined to Zhou Mingrui, who came to talk to her inexplicably.

Mu Tang was thinking about it, Qi Ran suddenly said coldly: "What's more suspicious, isn't it why the murderer knew that you would come to school today?" ”

Mu Tang was stunned for a moment, stopped and looked at him, "Yes, how could the murderer know?" ”

Qi Ran's eyes were gloomy, "The murderer knows that we are going to the imperial court temporarily, and he also knows that Wen Ziyue sent messages and calls with you, knows that you will come to school today, and maybe, knows that we are going to lure the snake out of the hole......"

Speaking of this, his eyebrows suddenly tightened, "Give me your phone." ”

"Huh?"

Mu Tang was stunned for a moment, took out his mobile phone from his bag and handed it to Qi Ran, "Is there a problem with the mobile phone?" Did someone install surveillance on my phone? ”

She shook her head again, "But you gave me this phone two days ago." ”

Her previous mobile phone was still with the police, this was a new mobile phone that Qi Ran bought for her only two days ago, and she never left her, how could the murderer have the opportunity to install surveillance?

Qi Ran looked at Mu Tang's mobile phone back and forth, the mobile phone is the latest model now, it is indeed the one he personally selected for her, and it has not been dropped.

The appearance of the mobile phone does not seem to have any monitoring equipment, but the hacker of the other party is a person who can silently hack the Z city government and the royal court monitoring, and it is not difficult to hack into Mu Tang's mobile phone monitoring and listening.

It's been charged in the car before, but I can't see anything wrong with it.

His eyebrows were cold, and he directly turned off his mobile phone, "Don't use this for the time being, I'll send you a new one in a few days." ”
