There were many secrets at Grand Mystic Mountain that no one was privy to such as the path to eternal life and the shackles of heaven and earth.
Also, no one knew how profound the Unholy One's cultivation was. The world only knew that his cultivation path was unique, allowing him to break the shackles and achieve immortality. A select few also knew he had been to the Great Maelstrom and obtained many treasures such as Buddhist relics, the Great Void Token, the four power cores, the Ten Classics, and so on. These were one of the reasons he was able to rise to the peak.
Apart from that, there were rumors about one of the Unholy One's treasures. It was said that the treasure was a treasure that surpassed all treasures. However, no one had seen the Unholy One using it so no one knew what it looked like. That was the reason it stayed only a rumor.
