The overwhelming killing aura shattered the clouds above the heavenly dome, as if an unparalleled ferocious beast had awakened, terrifying to the extreme.
Afterward, this massive commotion gradually subsided.
In the mountain cave, Xiao Ye was enveloped and covered by layers of blood light. He suddenly opened his eyes, which were originally pitch-black but now had a layer of blood-red light over them, piercing through layers of void, sharp and unmatched, rippling wave after wave in the air.
The killing intent on his body was roaring, like a beast bellowing.
"With one breath, I've elevated the Slaughter Principle to the fifteenth level!"
A slight satisfied smile appeared on Xiao Ye's face, feeling quite pleased.
Although with his current martial arts enlightenment and realm, understanding the Slaughter Principle was relatively easy, it still required a lot of time to analyze, fortunately assisted by the Time Tower.
