Merchant

 After standing on the plain for a few minutes, players were teleported to a random city by the system. Aizen ended up in a town called Inaross, which is a city with a medieval style.

 'People here are so real…' Aizen saw NPCs talking to other NPCs just like people.  Players ran through the streets in search of some mission.

 "Ma'am, do you want me to do something for you?"

 "Young man, why are you so excited?"  Her were confused by the mood of this player.  It wasn't just this lady. Other NPCs were also confused when they saw so many players making requests.  They didn't know why these people liked to fulfill orders.

 'They don't seem to understand our existence.  Why do they ignore the fact that so many players show up out of nowhere in town?'  Aizen thought.

 'Why am I questioning?  They were created that way.'  He shook his head at his stupidity.

 Aizen continued walking through the streets.  He liked to watch the scenery.  Several children, young people, and adults passed through the streets.  Many were happy, others dismayed.  The NPCs' facial expressions were so real that it was impossible to distinguish them from a normal human.

 'Missions…'

 Aizen logged into the game's forum and checked player posts.  The game forum was extremely active and many people were sharing their experiences.  You could access the in-game forum, record scenes, etc.

 FORUM:

 >Support Guilds |  Hot topic☆

 Aizen became interested in this topic, so he clicked.

 >Hi, my name is Haz.  I'm a player who likes to explore.  I'm posting this thread to explain to players about support guilds.  Support guilds are guilds made by NPCs to help players.  There are several support guilds and each one is related to a profession or a game mode.<

 >The Haz player has uploaded images.

 Aizen looked at the images Haz had uploaded in the thread.  The images were about the guild buildings.  Haz managed to find several guilds, among them are: Mages Guild, the Alchemists Guild, Merchants Guild, Blacksmiths Guild, etc.

Haz managed to find more than ten guilds.  However, despite finding several, he still hasn't come close to discovering them all.  It just showed how big the Arcane Universe is.

 'Merchant Guild.'  That was his goal.  Aizen closed the thread and went looking for the Merchant Guild.  The city that Haz had started wasn't the same city for every player, so they would have to look it up on their own.

 Aizen asked some NPCs for the location of the merchant guild.  After a few minutes of walking, he arrived in front of a giant building.  The building was luxurious with various ornaments all around. More than 40 floors.  Several people entered and exited the building.

 Aizen entered the guild building and headed towards the balcony.

 "Hi young man, how can I help you?"  A woman greeted Aizen politely.  She was the receptionist.

 "Can I join the Merchant Guild?"

 "Do you want to be a merchant?"  The woman looked a little surprised.

 "Is there a problem with that?"  Aizen frowned a little.

 "No. It's just that you look so young. Are you sure about that?"

 "Do not worry about it."

 'This NPC cares about people.'

 "Alright, enter your details on this card, in the meantime, I'll explain about the Guild to you."  The woman handed Aizen a card.

 "Well."  Aizen took the card and began filling it out.

 "The merchant guild acts as a means for merchants to sell their items and conduct their business, play the role of mediator during transactions, as well as providing support in sales. (...)"

 The woman explained everything about the merchants' Guild to Aizen.  The rules are simple and easy to understand.  Any RPG player would know about traders.

 "Here is your card. Merchants are classified into five levels: Bronze, Silver, Gold, Diamond, and Ruby. This card is valid on the entire continent of Vloyix, but it may not be valid on other continents. Be careful."

 "Thanks."  Aizen thanked the woman and left the Guild.

 [Congratulations, you have acquired your first profession.  A random feat will be awarded]

 "Huh?"  Aizen looked at the message that appeared in front of him.  He had already read about it.  It appears that players are given a random feat when choosing their first profession.

 'Infinity Inventory'

 -Your inventory has infinite capacity.

 If Aizen had his mouth watering right now, he would spit it out.  He never thought of getting something this good at first.  The players' inventory was limited, so they would have to empty them quite often.  Now he had gained infinite inventory.

 'This is perfect.  I won't have any problems with the goods.'  Even though he hadn't gained any combat talents, he was excited.

 'Excited…' It's been so long since he's been excited about something.

 'I should find a mission.'
