This used to be a martial arts MMO.
Now it's a gambling casino simulator with loot/RNG boxes available everyday of the year.
It's free to play, sure, but you'll NEVER catch up with those who pay. They purposely removed ALL side quests so that players can finish the main chapters and get to the end-game stuff which is constant dungeon grinding with less and less rewards each update forcing players to buy the required materials to upgrade their gear.
If you're thinking of playing this game...just run...
