"When we found Xiao Wu in the hotel this morning, there was a series of numbers on the wall. The things that Xiao Li was holding just now were brought over from Xiao Wu's house. The whole process was documented," Xu Lan kept staring at Li Xiu while he was talking. He was amazed by Li Xiu's self-composure, as he remained the same except for signs of mockery for a fleeting moment.
Xu Lan passed on each item from the carton box to the others, all of them contain scribbles of numbers and lines. Each number had the corresponding lines, which translate to its complementary letter.
The corresponding lines for 0100/1001 were ·—··/—··—. According to the Morse code chart, ·—·· codes for 'L' and —··— codes for X. The combination of both letters would be LX.
Xu Lan enlarged the message from his cell phone onto the computer screen. The message was about how Li Xiu taught her to use the Morse code chart.
