All explorers who have personally ventured into or prepared in advance for the "Night Parade of Hundred Demons" understand one thing—compared to the "Curse Spirit" which can be immune to most forms of damage, "Corpse Spirit" is the more irritating creature.
The reason is simple, because these ghostly things are troublesome, and yet they don't drop Erosion Crystals upon death.
They share similar traits with dark creatures.
Fortunately, a combination of "Veterinarian" + "Warrior" + "Mermaid" can sweep away large groups of "Corpse Spirits", adding a bit of motivation to this combat with no positive feedback.
So, when Xu Shu rode out on his fish-headed horse, the others were slightly surprised but didn't say much.
Because this was a normal action in line with the rules of this relic.
