Chapter 325: The Origin of the Thunder Devouring Sword

The demonic creature lay in the exploded cave on the mountain side, its face seemingly contorted with a hint of pain.

Its gaze towards Xu Ping'an was filled with intense astonishment.

The power of the Sword Array itself hadn't harmed it, but the Indestructible Thunderous Force contained within the Sword Array had eroded a portion of its essential elemental power.

This made it feel extremely displeased, that it had actually been injured by a Fifth Rank ant.

"Human child, you have enraged me," the demonic creature glared at Xu Ping'an with a gaze dense with killing intent.

However, Xu Nian's face showed not a trace of fear; instead, he let out a slight sigh of relief.

The Indestructible Lightning was indeed effective against the demonic creature, as he had clearly sensed its aura weakening somewhat just now.

This indicated that the Indestructible Lightning had indeed inflicted substantial harm on it.
