Using her profound spell, Dongxuan Immortal trapped over twenty elite disciples of the Emei Sect in various "Gu Pits," and then unleashed a potent curse.
Her Witch Gu Curse was tremendously powerful, bolstered by the Golden Silkworm Gu that she had grafted with learning from the Green Robe Ancestor's Mysterious Yin Scripture. Although she hadn't refined the Mysterious Yin Pearl, she employed the Gestating Gu Technique to separate from her own body her Second Primordial Spirit, Third Primordial Spirit, Fourth Primordial Spirit... as the Gu eggs developed into Golden Silkworm Gu.
Each Golden Silkworm Gu held a power similar to that of the Mysterious Yin Pearl, employing the Five Great Snake Gods externally, and internally using the transformed Golden Silkworm Gu, she cursed each of her enemies.
She was literally staking her life, casting with all her might.
If used against anyone else, even someone with an Undying Body, like the venerable Tian Chi, would find it unbearable.
