Divine Sect's secret technique, Hundred Lives Tribulation.
Granny Huai's cultivation of the secret technique, Hundred Tribulations Returning to Fate,
An Jing did not understand the difference between these two secret techniques, but he could comprehend that this was the enhancement developed by Heaven's Will Demon Sect after extreme depths of research into the Fate Pattern, a secret technique aimed at altering and utilizing the Fate Pattern.
Perhaps... the transformation of Heaven's Will Sect from its original mysterious sect into the current Man-Eating Demon Sect was due to the misuse of these secret techniques, or perhaps it was the loss of the constraints of the heavenly laws.
But Granny Huai was different.
Even though she practiced secret techniques, An Jing could see that as she herself had said, she had never harmed anyone.
