Several Blood Exchange Realm masters of an unknown origin were nearby, and there was no way he could let his guard down.
"To enter Xunmu Cave Heaven, one must break through a passage during the Void Tide. Elder brother, when you sent those people in a few days ago, did you notice anyone unusual?"
At this point, Cheng Zu spoke openly and calmly.
Someone unusual?
The Dragonwood Island Master's mind was clear as a mirror, and he immediately understood who Cheng Zu was referring to. He wasn't well-informed about the intricate powers of Da Xuan, but since this wasn't a dispute from the Outer Sea, he naturally wouldn't intervene deliberately.
After hearing Cheng Zu's inquiry, the Dragonwood Island Master responded frankly, "Indeed, there was one person who was not ordinary. His Vigorous Inner Breath was incredibly profound, far surpassing that of a typical Marrow Cleansing Realm master."
