As the words of the Immortal King level powerhouse fell, a concealed Void Channel opened, and a black goat horn-like divine object was placed into the hands of the Brocade Honor Immortal General.
This treasure was indeed a "divine object" rather than an Immortal Artifact. The Marsh Beast was an ancient divine beast, rumored to have the ability to determine the truth. After listening to both sides of the argument, it would touch the side that was being unreasonable with the horn on its head.
When the Immortal World was first established, the Marsh Beast ascended. In the following long years, its whereabouts were unknown, just like those once-powerful Emperor Venerables. However, a horn remained in the Immortal World. Today, the Immortal Race has crafted various immortal artifacts that can discern lies, with the most accurate being the twelve "Unfalsified Words" immortal artifacts refined back then by the "Heavenly Furnace."
