During Klaus's 8th incarnation, he clashed with hundreds of thousands of enemies, one of whom was the sect master of the Eternal Furies Sect.
It's a female-only sect in one of the strongest worlds in the universe.
Kaden clashed with her because she was a member of the Heavens Cult, a special group of cultivators who dedicated their time to hating the paragons.
Back then, Kaden was angry when Pickle Berry nearly died saving him, so when he located this sect master, he went in full force, resulting in a battle that destroyed half of the Eternal Furies Sect.
In the end, Kaden killed her and left. However, the battle was far from over. While Kaden came, did as he pleased, and left the sect in ruins, one person took offense.
What Kaden didn't know was that while he made sure nobody else except the sect master died, one other person lost something big, and that was the Red Fury.
