This remark is rather hurtful.
Back at the Black Dragon Cemetery in the Underground World, Blood River Commander was struck fiercely with an axe by Liu Zhenhuan upon his first appearance. The space-time channel known as the "Gate of Bone Tomb" connecting two planes immediately collapsed; this esteemed ruler of the Netherworld, the powerful Nirwinke, was just hit without even a basic chance to fight back, disgracefully earning a severe lifelong aftereffect!
After this incident, Nirwinke undoubtedly became the laughingstock of the entire Netherworld.
