Start the "micro.wav" in Chapter 6 to start the challenge. After unlocking "Crave Wave", continue to "Chariot-REVIIVAL" through "cereris", and then go through the dialogue and melody directly to "Retribution".
1. Start the game and play the audio track "micro.wav" of Chapter 6 of the main story (the illustration shows a girl holding a microwave oven), and then challenge the first song.
2. Directly click the icon in the lower right corner of the screen to enter the music interface, so that we successfully unlocked the first track - "Crave Wave".
3. After completing the first track, select and challenge "cereris" to proceed to the second track "The Chariot-REVIIVAL". After a successful second challenge, we will be eligible to unlock the next two tracks.
4. After the second track is completed, a dialogue will appear in the game, during which a melody that seems to be the goalkeeper's theme song will sound, and then the game will jump directly to the third track - "Retribution".
5. If you restart the game and flip your phone over the illustration of the second track, you can unlock the fifth track - "Luminesc".
6. Finally, by completing a very challenging Demon King song "Distorted Fate", we will be able to unlock the game level in Chapter 8.
