The moment the Destructive Energy appeared, the three Yin souls all looked like they were shrinking back.
They were clearly Yin souls, yet they actually had such a human-like expression. This was really enough to make people click their tongues in amazement.
Boom!
Ling Han brandished Destructive Energy, and as he shot out a punch, fist light was shot out, mixed with Destructive Energy. This was the strongest weapon against Yin souls, and could even allow him to battle surpassing his cultivation level.
Otherwise, how could he kill a Spirit Transformation Tier Yin soul?
Logically speaking, since the three Yin souls were so afraid of the Destructive Energy, why didn't they run?
Indeed, they kept retreating, but it was only limited to the vicinity of the Blood-Patterned Dao Stone. There seemed to be some kind of power, or even Regulations, that restricted them from leaving.
