Let's rewind time just a little. At this point, Mordred was still fighting Spartacus. But the brat's mood was anything but good.
"Tch! You think this paltry level of strength can stand in the way of me, the 'King of Knights'? Don't underestimate me!" With the explosive force brought by Mana Burst, Mordred knocked aside the heavy shortsword in Spartacus's hand.
As for why the words "King of Knights" were in quotation marks, most people probably understood. If the brat ever faced her glorious father, she would definitely be the one beaten so badly she would lose all sense of direction.
Not to mention, if Artoria failed to win, she would be letting down that old rogue who had taught her swordsmanship.
"Mwahahaha! Oppressors! Defeat the oppressors!"
Fine. By now, Mordred had completely lost her patience.
Both of them were Berserkers, but Spartacus's combat instincts were far inferior to Shirou's. While this was the proper way for a true Berserker to behave, Mordred still found it irritating.
A guy like this had absolutely no value as an opponent!
That was not the only reason Mordred was annoyed.
She swung the king's sword in her hand and, while her opponent was completely undefended, carved a sinister wound deep enough to expose bone.
Such a wound would count as a severe injury for any Heroic Spirit. But in the next instant, the damage caused by that horrific wound was converted into magical energy by Spartacus's Noble Phantasm.
An overabundance of magical energy clogged the wound, forming a tumor-like lump of flesh. Judging purely from the effect, there was indeed no need to worry about that wound anymore.
That was what made Spartacus so troublesome. If he could not be crushed in a single blow, he could never truly be dealt with. Recklessly
