Learn skills in Perfect World
In Perfect World, you don't learn skills (Perfect World Gold) naturally by leveling up in this game that just unlocks them. You still have to go the trainer of your class in town. The towns that have skill trainers for your class are the 6 big towns and some of the towns you visit before level 20. Pay attention that Thousand Streams, Archosaur and Dream weaver port own all trainers, not just one race.
To learn skills, you need money and spirit, and sometimes, the required level of the previous skill. Also, some skills require you to level up your Cultivation level (Perfect World Silver). To do this, finish the Spiritual Cultivation quests, they start with an automatic pop-up to send you to an NPC who starts the actual quest. They are the yellow-named quests, you can't really miss them. Finish one and your Cultivation will increase, allowing you to learn more skills. Hope it could help you more or less.
