Daoist Jin Lin was really startled. What did he hear? Wasn't this the ancient incantation technique that could appear after one developed the Dao Race's breathing technique to its ultimate state?
Wu Lunhui knew this, too? Even someone as calm as Daoist Jin Lin was strongly affected by this in an instant.
That was because he had only slightly dipped into it and couldn't master it completely!
The history of the Dao Race's nine lettered incantation was so great it startled the heavens. The race's elder once said that this should have been a technique that circulated in the Yang Realm. It was very difficult for them to cultivate it successfully in the Yang Realm because the Dao Race's breathing technique was incomplete and lacked sufficient Yang qi too.
Based on what the Dao Race's ancestor said, a few powerful breathing techniques in this universe originated from the Yang Realm.
