Clever Little Cherry

Gu Ci's mind shook for a moment, and all the romantic sentiments of wind, flowers, snow, and moon faded away. She went from being lost in love to a calm and composed state. "Where are they?"

"In a residential building. I've been watching them for two days. I can pretty much confirm that the master and Ji Chi are together."

This phone wasn't Gu Ci's usual mobile; it was an untraceable number. Gu Ci wasn't afraid of government surveillance. "How did you find my brother?"

"We have a secret code between the master and me. Only we know it. I guess he left the mark on the roadside when he took Ji Chi out for medical treatment. Within a two-kilometer radius of that mark, I've been searching every house one by one. At night, the master will use light to reflect a rhombus symbol on the opposite building. That's my signal."

This code was known only to Qin Wan.
