"The Godfiend's Mark!" Before Zhan Ting could finish, Little Black had already exclaimed.
"What Godfiend's Mark?" Lonemoon frowned and asked in an irritated tone.
"The Godfiend's Mark is my clan's contract seal." Little Black explained, "The seal will only appear when someone swears by their Demon Soul and sets up a Demon Contract. Just like the immortals' Heavenly Dao vow, once it is established, they are bound by the Godfiend to accomplish it. Otherwise, the Mark will make the person who set up the contract pay an even bigger price. However, the Demon Contract cannot be set up unless the cultivator is at least a Skyfiend, otherwise the Godfiend will not respond."
"Contract?" Lonemoon looked closely at the pattern on the pendant, "Shen Ying, where did you see this pattern… Wait a minute! This pendant can't be the one that Hui Ling was wearing on her neck?"
"Yes." Shen Ying nodded.
