Naturally, the Lords had no intention of letting things go Sarah's way, so before she could reach Reed, the elite assassin undead which Aslan summoned earlier, appeared above the crazy girl.
Seeing the bone dagger coming at her, Sarah smirked, her pretty eyes shone in an ominous purple light, which resulted in the arm of the elite undead… melting before it could reach a meter away from her head.
"You really should stick to your assigned opponents, death nether is corrosive and poisonous after all~", said the crazy girl with a mocking voice.
Basically, she used Aslan's death nether as fuel to poison the assassin undead, since the death nether is what sustains the body of the undead, when Sarah turned it into poison, the thing was destroyed from the inside, hence why Sarah didn't even need to use a martial art, how can an undead who lacks a sense of self defend against a technique like that.
