Yan Liuyuan's Curse Manipulation had somehow been turned into a unique production method by Ren Xiaosu. That caused Yan Liuyuan to subconsciously get the idea that he had to arrange for some food to be found whenever he wanted to curse the other refugees.
Under these circumstances where everyone else was unaware of what was really going on, Li Qingzheng had suddenly become their group's mascot.
Regarding Yan Liuyuan's power, Ren Xiaosu decided that it was still better to keep it from everyone for now, because this power was simply too strange. Even he couldn't understand it.
Sometimes, such abstract powers would make people even more fearful. So Ren Xiaosu reminded Yan Liuyuan to keep it a secret. This matter would only be known to Yan Liuyuan, Ren Xiaosu, and Xiaoyu.
