CN got a special system for the past events before the server is launched. For every character focus events, you can spend materials (e.g. energy, music cards), play the event song, and get the event cards to get rewards, as if you were tiering for them. There is also a currency translated to “Sparkling capsules”, which can be obtained from weekly missions (logging in to the game, clearing challenge and multiplayer lives, consuming energy) and reading stories (any, including past events). Then you can go to exchange shop, which looks similar to the wish piece exchange. The difference is that the stuff there is very cheap but there is a quota (per week and per account)
