Idk why production is so rare and people think that it was useless and wasting time to level it up... R u stupid author? For most of MMOs player it was the most common thing u r doing, every player raise that skill, most people goes to farm, fishing, cooking just to raise their production skill so itll become bonus income. Hell even most of them enjoying production more than battling monster and leveling just to get more gold and sold it via real money. U just afk fishing and farming while movie or reading this manga.
