"What do you mean?"

I didn't figure it out with my promise, what signal was located?

"I won't talk about this, you let Gu Ze tell you, so you don't have to wait for me to leak secrets again."

Gu Ze glanced at Xu Chengjing, calmed down and patiently explained to Xu Chengjing.

"You were stumped in the cafeteria before, I suspected that someone was operating behind it, and I told you that Xie Fei'er may also be a knife in the hands of this mysterious person, I wanted to catch him, so Xu Chengjing has been paying attention to Xie Fei'er's correspondence and social information."

Since he wants to instruct Xie Fei'er to do things, the other party will definitely leave a contact information.

Will he be staring at the phone?

"But Xie Fei'er didn't have much contact with that person, and I couldn't determine the other party's location for a while, so I could only keep hitting her and stimulate her to contact that mysterious person.

But I found out that this woman used a set of methods, using the photos of you and Xu Chengjing, and almost pulled you off the position of the school flower. ”

Therefore, Gu Ze could only secretly change his plan, no longer slowly plotting it, and began to take the initiative to let Xu Chengjing appear at the parent-teacher meeting, giving Xie Fei'er a fatal blow, and also allowing Xu Yu to breathe a sigh of relief.

"The blow worked, and she started to call that number more often, but the mysterious man, as if he had discovered something, didn't answer the phone until just now."

The promise is not stupid, and I understand it when I hear Gu Ze explain here.

"So you just found out about Fei'er's phone number and located that mysterious person, who was at school?"

Gu Ze gave her an appreciative look.

"Where the hell is that school?"

Xu Chengjing turned his computer around and faced the camera in front of him.

On his screen, a black background and a green line outlined a building structure drawing.

"Isn't this the student union building?"

Sun Wuchen stared at this picture and immediately reacted.

"How do you know that clearly?"

"Ugh." Sun Wuchen waved his hand. "Our school is funded by Gu Shuyan to build this student union building, the signal is the best, and the WIFI is not stuck."

"So that's why you didn't do well in this monthly exam?" Gu Ze immediately slapped it over.

Sun Wuchen hurriedly hugged his head and ran away.

"Can I be blamed for this? At that time, it was about to end of the season, the game was going to rush points, and the monthly exam was scheduled at that time period, and he did it on purpose. ”

"You still have the face to say?"

Gu Ze was so angry that he asked Qin Song to drag Sun Wuchen out, and after a while, Sun Wuchen's screaming voice came.

"Ahh Hitting someone is not a face, and hitting the face is not a person. ”

"Pain, don't slap your face, don't slap your face."

Promise: "......"

"But then again, we can locate the location of the other party's call, can't we directly lock down who the mysterious person is?"

"But what if that phone number is fake?"

"What?"

Xu Chengjing's fingers moved quickly on the keyboard, and within a minute, Xu's mobile phone rang.

The caller prompt was a string of unfamiliar numbers, and after Xu Promise answered suspiciously, Xu Chengjing's voice came from there.

"To make a call, as long as there is a signal, you don't necessarily have to use a calling card, the calling card is just a medium, a medium used to contact you."

Xu promised glanced at his mobile phone, and then looked at Xu Chengjing, who was talking to the computer on the other side of the screen.

Stunned.

I feel that my cognition has been refreshed, and it turns out that I can still use it like this when I make a phone call?
