He’d rather choose death over dishonor! Since Murong Yu was plotting against him, then he’ll just leave this place! If he continued hunting ghouls, there was a likely chance that all of his hard work would just end up benefitting Murong Yu!
It never crossed Nie Li’s mind that he’d suffer such a huge setback right after entering the Ghastly Ruins. It seemed like collecting spiritual stones by hunting ghouls wasn’t possible for him anymore. Aside from Murong Yu, there were still many others watching him. Even if he managed to collect some soul scales, the others might easily snatch them away. When Murong Yu was busy with Nie Li, Nanmen Tianhai and Huang Yu didn’t appear. Those two were probably not going to take action, as long as things stayed within somewhat reasonable bounds of the rules.
