The others might not have known that the Crimson Moon Demonic Tower was a rather terrifying demonic instrument in the Demonic Sky, but it was impossible for Chu Yuan not to know. He had often interacted with the Demonic Sky Clan and knew it well. The tower was renowned far and wide, and its name struck fear in the hearts of many.
According to legend, the Crimson Moon Demonic Tower was the pinnacle treasure in the Demon Realm. Its existence was akin to immortal treasures. For tens of thousands of years, it had dominated the Demon Realm.
The Crimson Jade Miniature Tower in Nangong Mingzhu's hand was not an immortal treasure of legend but a replica of the Crimson Moon Demonic Tower. It was a magical treasure that replicated the Crimson Moon Demonic Tower. Although it was only a replica, its might was rather frightening, far surpassing that of ordinary magical treasures.
