Su Mo also knew a little about the Demon Sealing Monument.
During the last mission concerning Myriad Worlds Mountain, he had spoken with True Sage Dao Saint in detail, so he understood it well.
It was said that the ancient demons buried in the Ancient Demon Graveyard had all been mighty experts of the Void God realm, powerful ancient beings with the ability to reach the heavens and span the earth.
The blood and remnants of those ancient demons had long since transcended the ordinary, possessing unfathomable power.
The Ancient Demon Graveyard had been specially opened for fallen ancient demons. The residual essence within would form all manner of Demonic Beasts.
The Demon Sealing Monument existed to suppress those Demonic Beasts within the Ancient Demon Graveyard, preventing them from breaking through space, emerging, and ravaging the outside world.
And this Ancient Demon Graveyard was the finest trial ground for disciples of the Taiyin Tribe and the Seven Great Powers.
As for the Ancient Demon Heart required by the mission, even True Sage Dao Saint did not know where it was. Once he entered the Ancient Demon Graveyard, Su Mo could only search for it himself.
However, True Sage Dao Saint had made one thing clear: the Ancient Demon Heart was the core of an ancient demon's body and was no trivial matter. The essence leaking from it would surely give birth to extremely powerful Demonic Beasts.
Therefore, wherever powerful Demonic Beasts were found, there might be an Ancient Demon Heart.
After observing the Demon Sealing Monument for a while, Su Mo returned to where the Dao Sect disciples were gathered and sat down cross-legged beside Lü Gang.
Not everyone had arrived yet, so the Ancient Demon Graveyard clearly would not open anytime soon. He might as well seize the time
