Upon hearing this, Su Han's pupils contracted.
The 'Dragon Ancestor' mentioned by the man in the purple robe was clearly the lower-class flood dragon that had appeared before, stretching a million feet in length.
This flood dragon was so powerful, it was infinitely close to the Spirit Transformation Realm, absolutely at the peak on this Dragon Martial Continent, such that even I would not be its match.
But before this, Su Han was not afraid, because for such powerful beings to take action would surely require a great cost, as seen when that lower-class flood dragon disappeared with the arrival of Sword Immortal Tomb and Giant Island.
They merely used the lower-class flood dragon and the wielder of the massive hand to arrive, not letting them make a move.
This reassured Su Han.
However, at this moment...
"Boom!!!"
The void buzzed with a loud hum, and the previously clear sky quickly dimmed with a surge of darkness.
