Upon returning home, Li Shi checked the logistics information in the mini-program to see where his high-speed camera, which he had ordered online, had reached.
Then he went on a certain procurement website and looked up a manufacturer that produced automatic induction wireless laser timers. He had located them on this platform when he was still in Yang Cheng; they sold professional electronic recording equipment.
However, their equipment required manual remote control over the speakers to issue commands. Li Shi last left them a message asking if they could add an automatic countdown function.
The factory's customer service representative had already responded and sent him a new link.
