Liang Yi had noticed that the senior of the Blood Book offered them the Blood Spirit, but did not give one to Uncle Jute, senior Zhou Yuqing, or Liu Rouxin.
Senior Qingqiu Mingli has already become a soul body, so it's normal for the Blood Spirit to possibly not work on her, but the senior of the Blood Book shouldn't be someone petty.
However, this item should be the reward from the previous life for finding the other Blood Demon. Although Liang Yi has not triggered the mission now, the mission reward is still rightfully claimed.
For players, the Blood Spirit may be a universal item applicable to all levels, a tool that grants a one-time death exemption. Because it involves resurrection, its effect might not be that miraculous.
But for natives with only one life, the significance of a one-time death exemption goes without saying.
