1.JJC is divided into 2V2, 3V3 and 5V5. You can't play alone.

2. First of all, we should set up a JJC team at the proving ground in Negran, where there is a NPC queue.

40 grams each, buy a letter from NPC, then let the people in the team sign it and send it back to NPC.

3. Then find the NPC in the queue and queue directly. When playing JJC, people in the team can't line up on the battlefield, otherwise they won't be allowed to enter JJC.
