The cultivation of the Ancestral Body of Evil was not difficult; all one needed to do was to continuously convert people to evil. For each person transformed, one would gain a portion of evil source. The more evil source one had, the stronger their power would become.
If Su Hang could not eliminate all the evildoers converted by Evil Lan, he would never be able to kill Evil Lan.
Most of the evildoers transformed by Evil Lan were essentially in the Primordial Demon World.
In other words, on Earth, Evil Lan was equivalent to having an Undying Body.
"It's quite interesting not being able to kill you, just what I needed for keeping a Golden Immortal Level Demonic Monster as a pet. You fit the bill perfectly." Su Hang quickly made his move, not wanting to give Evil Lan any time to recover.
Su Hang rushed forward, his strikes falling one after the other. Evil Lan's injuries stopped healing and worsened with each hit, his Physical Body bursting apart again.
