When Zhen Liu had sent out his zakos to explore the [Mines of Malevolence], he was fully expecting to witness scenes that looked straight out of a picture book about hell.
As such, despite being saddened, enraged and outright offended about how the kaijin of this knock-off lord were treating people, he was still able to somewhat keep his cool.
But as the zakos kept looking around and kept feeding him more and more instances of misery, pain and outright despair, it became harder and harder for him to do so.
Whether this was due to the innate nature of his [Chaos] that amplified his feelings to take action or because he still held some memories and morals from his old life was unclear, he just knew that he didn't want to see any more of these wretched scenes.
Alas, Zhen Liu needed more information, so he had to stomach all of this.
