Six-Nine Stardust is Little Immortal Xing Luo's self-created small star path killer move.
It uses six rank three Gu and nine rank four Gu, and can unleash the attack power of a rank five Gu. After seeing it, Fang Yuan buys it together with icy yarn for half an immortal essence stone. ch. 668 ch. 672
Deduction
It is her smaller killer move. Without icy yarn and six-nine stardust, Fang Yuan would not have been able to deduce icy drill stardust. When he saw the two moves, he judged they were the foundation of Little Immortal Xing Luo’s self-created killer move. ch. 670
