Trading with other player

This can be considered a slightly more advanced form than hunting zeny by just fighting regular monsters.

Because in addition to fighting monsters, you also need to monitor market fluctuations and explosive demand in the server, including implementing strategies of buying low and selling high and hoarding goods.

In addition, some professions can also craft valuable unique items, or receive crafting skills from completing quests.

How much you can earn depends on how knowledgeable you are about trending items.

Avoid Wasting Zeny

Let's talk about not wasting your hard-earned zeny.
More specifically, how to avoid spending more zeny on HP recovery items than necessary.
Fresh Fish and Meat seems to be a pretty good choice.
These two items are quite cheap and can be easily purchased at Tool Dealer. In addition, Valiant Shop also sells equipment that increases Fresh Fish and Meat recovery.
You can also complete the quest chain of NPC Melody to receive a beginner's equipment set (weapons are not included), making the first phase easier.

Tips

Use the /where to confirm your current location and make sure you are not lost.
Use Fly wing or Creamy Card to quickly travel to random locations on the map instead of walking.
You will pick up equipment that you cannot wear, go to NPC Healers in the cities to have them appraised.
