Fernan did exactly as he had said he would, showing no reaction to the decisively retreating attackers. He only continued to defend against those who were left behind to 'pin him down,' without any intention to capture someone or take advantage of the situation to pursue.
However, just because he didn't react, didn't mean others felt the same way.
Two streaks of dark purple Cold Light flashed by, and two figures who were running headlong fell to the ground, their heads continuing to fly five or six meters in the air before landing on the ground with expressions of terror.
Then, another seven or eight fierce flashes of Cold Light appeared, and the attackers at the front clutched their throats, falling down in despair.
Unbeknownst to anyone, around thirty figures dressed identically had appeared around Duke Fernan's domain, silently causing a bloodbath.
