City of Freedom (Adam Online Book #2) LitRPG Series

In order to gain access to Adam Online's closed locations, Leonarm needs to max out his level pretty quick. Help comes from the most unexpected quarter: a human/NPC hybrid who has access to all of the game's items and is privy to its deepest secrets. But Leonard is not alone in this race. The rumors of new locations packed to the brim with epic loot begin to spread among ordinary players. The only known transition point to the new map is being controlled by the Black Wave guild - the very players who killed Leonarm with a mysterious weapon at the very start of the game. The guild now blocks every attempt to get to the new worlds. This leads to the greatest clan war in the history of Adam Online: a single guild against all the other clans and players. And they won't hesitate to employ their mysterious weapon, the most destructive force in the entire game world.
