Survival on an Island, I Just Automated Production

Everyone wants to survive, starting with a 4 square meter desert island. Everyone is racking their brains for a mouthful of fresh water and a piece of biscuit. Lin Yuan added two pieces of grass and a rope to form an animal trap. Two bones are combined into flint and steel. "Li Feiyu has the little green bottle, Wang Mazi has the Tianni Bead, and I, Lin Yuan, have the synthesis system, so why not!" While others gnawed on raw meat, he cooked broth. While others are exposed to the rain, he lives in a wooden house. While others rowed rafts, he drove a battleship. Everything can be synthesized, and he has the final say in this sea.
