Huaihai City Transportation Center.
An Qingyu hung up the phone in his hand and looked at the white-dressed girl floating beside him, surprise appearing in his eyes.
"Just like that?"
Jiang Er nodded. "Mm."
"Isn't the range of your ability only one kilometer? How did you interfere with Shen Qingzhu's phone from here? There has to be at least four or five kilometers between us."
"One kilometer is the range covered by the magnetic field of my brain. In other words, it's my movement range, not the range in which my ability can take effect." Jiang Er explained, "I didn't personally go over and alter that phone. I only changed the signals covering this area through the magnetic field.
The essence of modern mobile communication is information exchange between terminals through signals. Signals are transmitted through base stations scattered across different locations, enabling long-distance communication. It's like a vast net spread over the city, and I can enter through any node of that net and directly affect the radio signals themselves with my ability.
So, in a modern setting, my ability can affect anywhere covered by a signal."
An Qingyu seemed thoughtful. "In other words, if you wanted to, you could affect any phone in the country at any time?"
"Also radios, televisions, computers, and every electronic device that transmits information through frequency signals... provided I know that device's signal code." Jiang Er added, "This ability only appeared after I became a ghost. Before that, I could only affect electronic devices through magnetic fields within a one-kilometer radius."
"No wonder you had Shen Qingzhu knock them out first, then call you beforehand." An Qingyu nodded, then asked, "But if an electronic device's ability to exchange information is blocked, can you still infiltrate it?"
"If it has no information exchange with
