The Supreme Emperor Tower of the Heavenly Emperor was crafted predominantly from Chaos Stones sourced from the Chaos Void, combined with an array of other top-tier Divine Golds and immortal materials, constructed into a rudimentary form by the joint efforts of several top Divine Craftsmen from the Divine Land World.
Then, the powerful True Immortal, Jade Emperor, spent thousands of years consecrating and forging it with infinite Qi Luck, thereby creating a mighty Immortal Artifact.
This Supreme Emperor Tower was top-notch whether used for offense or defense. Once activated, it suppressed space with its terrifying power, and even the top-tier Divine Power, Wind and Thunder Move the Nine Heavens, wielded by the Saint Lord of Wind and Thunder, was unable to harm it in the slightest.
