You can now start on the Equipment Bonus Quests from your Class Trainer in Job Center, which will grant you massive exp and some nice equipment as a reward! Meanwhile, the Captains of each city are recruiting volunteers to eliminate the monsters for them.
You might wonder how you could venture around without nice gear, but don't worry. After that, it's time for you to do some real quests! Just follow the system tips and finish all the quests, and you'll be able to learn some basic in-game functions and operations. The auto-path will lead you to different villagers in Twin City and the Market. Right after you create your character, the Beginner's Quest will be automatically activated.
