Stranded on a Desert Island with Some Girls After a Plane Crash

Stranded on a deserted island from the start! No lighter, no knives, no useful survival kit, only a backpack full of useless stuff! Relying on a hardcore survival system, rubbing sticks to make fire, digging pits to collect water, making stone axes, and tearing snakes apart with bare hands! After surviving the initial period, starting to make stone tools, pottery, smelting, domesticating animals, farming… Then stealing some leisure time from the busy schedule to patiently teach the girls some small life hacks!
