紧凑灵雷爆裂

Compact spiritual thunder array exploding on a game board, purple-gold lightning crack in a tight 3x3 blast. Punchy close thunderclap, short shockwave, brief electric crackle, then fast decay. Not a distant storm, not a 5-second cinematic thunder, not a bomb in a war movie, not bass drop. Magical cultivation lightning, about 0.75 seconds.
