One after another the demons died, at the same time, Cao Liangjei also transformed into some kind of killer who vowed to destroy every other enemy despite feeling a trace of reluctance in his heart. Deep down, he knew all the demons weren't the same. They were the cornered beings who didn't have a way out no matter what.
Thus, he was a little soft to kill them all. For instance, when he killed his enemies in the past, he would like to torture them a little by giving his enemies the most painful death possible. But right now, it turned out that he still had a soft portion left in himself that stopped him from killing them ruthlessly no matter what.
