"Hundred Slice."
After witnessing how Mordred easily countered his Level 8 technique with an inferior one, Michael reevaluated his threat level. If a dozen slashes were already powerful, a hundred of them would be monstrous.
In order to counter Mordred's barrage of certain fatalities, Michael quickly estimated the appropriate number of forces needed to fend off those hundred heavy and fast blades and executed the right technique for it.
"Fuck! Thousand Slice!"
To provide the right response to Mordred's Level 8 Hundred Slice, Michael answered him with Thousand Slice, a Level 10 Sword Art technique. The weaker with superior technique versus the stronger with inferior moves.
Ching! Ching! Ching! Ching! Ching!
A storm of blades occurred in the hallway as the two swordsmen exchanged blows. Their battle was so furious that it produced gushes of wind in the area that almost blasted Sabrina.
