The expressions of their faces changed drastically as they retreated. One of the Celestial Strong Exponents shouted at the Ghost Elder: "What are you doing!" However, as soon as he had spoken, he met with an oncoming attack. The swift moves had murderous intent without an ounce of mercy.
By right, there were four Celestial Strong Exponents and two Nascent Soul devilry cultivators, so it stood to reason that they shouldn't be afraid of the group of five cultivators who were attacking them. However, they were shocked when they made their move against them. Especially when the black robed youth within them had attacked one of the Celestial Strong Exponents in their group. His boldness and courage shocked them even more.
Was he not afraid of death? Oh, that's right, they were trained to be killers who obeyed commands, they had all taken the Heart-Scattering Pill, why would they be afraid of dying?
