The Annihilation Realm King's Fist, a secret technique that harms its user before it kills its target, was now mercilessly ravaging Sterl's body. If this process wasn't interrupted, it could even obliterate him completely.
Of course, any normal person would never be killed by their own power—let alone someone like Sterl.
Given the strength of his current soul, Sterl could easily release the Annihilation Realm King's Fist before his body reached its limit, greatly amplifying the destructive power in the process.
As for the damage caused by the Annihilation Realm King's Fist during its gathering phase, with Sterl's vitality and regenerative abilities, that was hardly a concern.
In other words, for him, the self-inflicted damage of the Annihilation Realm King's Fist was not really a drawback. Apart from the long charging time, it was a near-perfect ability.
