Severed Glacier...
If there was someone Emodao loathed aside from the headhunter Xu Rouguang... it was his pet hound Severed Glacier. What was the reason why he had to push for the phantoms to mutate and become close to intangible and yet borderline powerless demon spirits? It was to completely wipe off the scents and signatures of the demon army.
Severed Glacier was an ice mountain spirit, but he once served as a hideout of demons. If there was someone who could sniff them and find them without much effort, it would be him. That was why every time the Imperial Army and the demon army clashed, Emodao would handle Xu Rouguang while the sentinels forced their entry to kill Severed Glacier. Without their sniffing hound, the Imperial Army's movements would be crippled.
