Kiyomi Liuli followed the instructions, threading cables and climbing ladders, quickly completing the installation of the "simple communication gadget." During the process, Kiyomi Koko heard the noise and came out to see, but when she found out it was just two high school students fooling around, she didn't pay much attention, only reminding Liuli to be careful before shrinking back inside to continue watching TV.
The installation wasn't difficult. According to Kiyomi Liuli's research, this so-called "simple communication gadget" was actually a toy version of a "high-altitude zip line," consisting of load-bearing cables, traction cables, and a drive unit powered by batteries. It was Nanahara Takeshi's job to only let her build the zip line, not providing her with the grippers or the "cable car," which were probably still in his possession.
