Notice that there was another King-level aura behind him, the already somewhat flustered Porcupine-Man's actions became even more chaotic, but his attacks became increasingly fierce, somewhat like a frantic fight to the death.
Alpha took note of the situation and didn't rush. His Sword of the Wind Chaser danced flexibly, each swing taking a slice of flesh from the Porcupine-Man. Even though the Porcupine-Man's recovery speed was extremely fast, it gradually started to fall behind.
After all, apart from the sharpness of the Sword of the Wind Chaser itself, each attack also brought with it endless wind blades from tricky angles, which left the Porcupine-Man not knowing where to defend.
Bai Qi wanted live capture, so Alpha didn't choose the Sword of Death or Undying Flame. Instead, he chose the Sword of the Wind Chaser to defeat the Porcupine-Man.
