After eating, the three prepared to set out. Li Yifei packed blankets and clothes into the backpack, but from the plane wreckage, he only kept a few small pieces, leaving the larger ones behind.
The three had eaten something in the morning and felt much more spirited, ready to depart. However, before setting off, Li Yifei carved a few words into one of the large pieces of wreckage: "Three survivors, Li Yifei, Xu Shanshan, Yanzi, heading north."
This was a signal left behind. If the rescue team were to come, they could follow this direction to find them. Moreover, it was also a message for their families, to ease their worries somewhat.
