Mutual destruction!
That was indeed the case!
Fragarach possessed the property of Answerer, allowing it to kill an opponent in the "past," before they had used their ultimate move, thereby erasing the ultimate move they had already unleashed in the "future"!
However, the instant Gae Bolg was swung, the result of "piercing the heart" had already been decided. This "result" was determined by causality. Even if Fragarach killed its opponent in the "past," Bazett's heart would still be pierced!
Therefore, if Wu Yan used Gae Bolg while Bazett used Fragarach, and the two clashed, then in the end, both their hearts would be pierced!
The only outcome would be mutual destruction!
Of course, Bazett believed that there was no way Wu Yan was foolish enough to want to perish alongside her just because he had said that.
After all, just moments ago, her supposedly unstoppable Fragarach had lost its effect!
Bazett did not know what method Wu Yan had used to nullify Fragarach's ability. Thus, she had only mentioned "mutual destruction" to probe him...
Unfortunately, Bazett had miscalculated...
"Mutual destruction?..." Wu Yan closed his eyes.
"If that is what you want, I can grant you that..."
"Yan..." Hinagiku, Mikoto, and Rin Tohsaka froze upon hearing those words.
"What did you say?..." The disbelief in Bazett's gaze as it fell upon Wu Yan deepened.
"What do you mean?..."
"Try it..." Wu Yan swung Gae Bolg in his hand and slowly opened his eyes, exposing his golden irises to the air.
When Bazett saw those dazzling golden eyes once more, the vigilance in her heart instantly rose to its peak.
Because those brilliantly colored eyes were no longer calm...
Killing intent?...
Anger?...
Malice?...
Perhaps
