Cement: As terraces are used more often better materials to build them must be made; finally, a mix of limestone, sand, and water was created which is sufficiently strong enough to be used in our great terraces. This material has also begun being used in buildings or as a binding material between stone bricks.

Pomelo Cultivation: {This link as well} For many years we have gathered pomelo from the wild, now we have began raising the trees ourselves to give us even more of this delectable fruit.

Laminar Armour: Frightened by the stories of horrible people from the west (pirates) a blacksmith took it upon himself to begin creating a defense from melee attacks: strips of iron layered over each other and banded together with rope.

Curing of Food: Fishing trips have always been limited in length because the fish would go bad after being caught. Now a solution has arisen: curing of fish. This can either be done by smoking it over a long period of time or washing it in salt or sugar. This lengthens the distance fishing trips can go and has encouraged other developments in this area.

Tangle Nets: Now that fish can be stored for periods of time new nets have begun being constructed in order to catch even greater quantities of fish.
