The four of them had been ordinary people who were wrongfully killed.
When they died, the road to the underworld was still clear, but their souls hadn't traveled it to seek justice from King Yan as Xin Huohuo and the others had guessed. Nor had they been collected by Bei Mingyuan. Instead, they were trapped and tormented by Ma Kai, and now, they had been refined into his puppet ghosts. How could the ever-righteous and principled Black Impermanence, for the sake of capturing Ma Kai, bear to let them be annihilated in Purgatory, losing their chance for justice and reincarnation?
That would be the greatest injustice of all!
Had they committed some unforgivable sin? Even if they had, the underworld had its hells. After atoning for one's sins, there was always a chance to repent. But they had done nothing more than know a wicked man! They were completely innocent!
