No wonder he was so panicked, in this era where the King Realm was hidden and saints remained unseen, a Grandmaster was the strongest among men.
Because once a martial artist completed the Spirit Qualification of their physical body, the secondary transformation of Spiritual Power could no longer harm them, and the explosive power limit of most Fierce Realm Spirit Arts was just tens of thousands of points of spiritual damage.
Therefore, for most Fierce Realm martial artists, they didn't even have the qualifications to injure a Grandmaster, only a rare few at the pinnacle of the Fierce Realm might have a chance to wrestle with a Grandmaster, but even then, victory would be extremely difficult.
This is also why the Devil Lord Hook Chen was able to make such a name for himself—as a powerhouse at the peak of the Fierce Realm, he truly managed to injure the Victorious Venerable Liaoyin in a head-on confrontation.
