Using 'Sword Intent' or 'Dao Rhythm' in an 'overload' state means that Rio and Link are going beyond their usual output by pouring an immense amount of mana into their respective skills.
The user's control over their skill weakens in the 'overload' state, but their output significantly increases, allowing them to deal more damage.
Link and Rio both took their stance and attacked each other with the maximum strength that they could use.
Link covered his fist with 'Dao Rhythm' and punched towards Rio; on the other hand, Rio covered his sword with 'Sword intent' and slashed towards Link.
Their attacks collided, and the ground cracked.
The collision of two legendary rank skills at such intensity caused even the space-time fabric to tremble and start cracking.
Even the SS-rank barrier trembled a bit, and the massive air pressure created by their attack destroyed the whole stadium ground.
