After waiting for about a minute, Yang Yifeng's cellphone finally rang.
Yang Yifeng swiftly answered the call and placed it to his ear.
"Hello?"
"Found it, the signal originates from Donghai City! The city you're currently in!" the voice on the phone was still cold, mixed with the 'click-clack' sound of fingers tapping on a keyboard.
What!
Upon hearing this, Yang Yifeng was also taken aback, but he quickly regained his composure and asked with some uncertainty, "Are you sure? Does the signal really come from Donghai City?"
"Yes. Mr. Yang, how about my computer skills, do you still need to doubt them?" The other party first responded affirmatively but then spoke with a slightly sarcastic tone, "However, I can only trace it this far because the source of the signal has been manipulated. I can only pinpoint it to a city-scale range."
