The bow-drill fire-starting method requires the use of suitable plant fiber materials to make a simple rope of appropriate length.

Since Su Ziqing currently has three companions, unlike the male protagonist in some survival shows, she doesn't have to figure everything out on her own.

Therefore, to speed up the process of starting a fire with a bow drill, Su Ziqing decided to use the "two-person wood-drilling fire-starting method", a cooperative effort between her and Shen Gu.

One person uses a wooden lid with a groove to fix the drill shaft on the drill board, while the other person wraps the "simple rope" around the drill shaft a few times and then quickly pulls it back and forth.
