For the moment, setting aside the power of the Heavenly Demon Armor secret technique Kuang Feng had mentioned, the mere fact that cultivating it required a thousand Yin Souls had already left the few people present visibly shocked.
Over a thousand Yin Souls were, of course, not the souls of ordinary mortals. Even the souls of low-ranked cultivators would likely fail to meet the requirements. As for killing cultivators at the Ghost Commander stage, putting aside whether it could actually be done, if someone truly acted so, the resulting karmic sin would already be far beyond what ordinary cultivators could bear.
The most obvious manifestation of such karmic sin was that cultivators would become stained with death qi. Ordinary people could neither see nor sense this death qi.
Yet it truly existed. The more people one killed, the denser this death qi became.
Although this death qi could not be seen, everyone in the Cultivation World knew that it was no good thing. Once it reached a certain level, it would inevitably affect a cultivator's mind, causing them to fall into a demonic mental state from which it was difficult to escape.
Of course, this death qi was not impossible to dispel. Eminent Buddhist monks possessed many divine abilities for dissolving it. However, if the death qi became too abundant, even eminent Buddhist monks would be powerless.
