"It seems the Nine Extremes Blood Sacrifice Technique of Great Perfection has its own profound mysteries,"
Fang Wang looked up at the Sword Immortal performing the blood sacrifice ritual on himself and thought so.
He discovered that not only could he see the limits of the Sword Immortal, but he could also forcibly undo the opponent's Nine Extremes Blood Sacrifice Technique, meaning he could revert an opponent, who'd reached their limit, back to their original state, though their lifespan wouldn't return and death would still come as it should.
The Nine Extremes Blood Sacrifice Technique of Great Perfection could, in essence, suppress anyone who mastered the Nine Extremes Blood Sacrifice Technique, unless the opponent also reached the Great Perfection Realm.
Such a suicidal secret technique, it was estimated that no one would study it to the extreme.
As Fang Wang thought, he soared into the sky.
