1.update construction and science to level 2,u will see a cloth hut
2. Repair the cloth hut
3.make fish bone tools first
4. Drag one person to take the salt water
5. Let another person cut the vines. He/she will get the tool by him/herself
6.boil the salt water
7. Once done cooking, let one person take the cloth pulp to the beach
8. Drag as many people as possible on the pulp.
9. They will take the cloth and store it in the cloth hut!
10. Then u can repair the bridge and the fishing net. (Fishing net repair requires 6 cloth which means u need to make two pulp pots, or u could drag two people on the pulp at the same time so that they will make 6 cloth! Save your time)
Hope it helps!
