"These guys are really treacherous, even using poison. The knife that person used earlier was poisoned, and judging by how quickly the poison is taking effect, it must be a potent one." Xiao Yifei hurriedly helped Muyun treat the wound while analyzing the symptoms of the poisoning.
"This is a poison that causes blood necrosis. Your blackened blood is because the poison has destroyed the red blood cells. If the toxin in your blood isn't cleared quickly, you'll be dead within half an hour." Xiao Yifei said, his face somewhat grim.
"Half an hour? That doesn't sound challenging enough for you." Muyun smiled as he spoke. Despite speaking weakly, it still made Xiao Yifei twitch his nose.
"Alright, stop being stubborn at a time like this. I've dealt with this type of poison before, but you need to cooperate with me, or no doctor can guarantee a cure for everything." Xiao Yifei said sternly.
