Emily also frowned slightly, staring at the device gently emitting mist, her nose twitching as she sensed a faint scent of grass mixed with mint.
"What kind of potion is this? I don't think I've seen it before," she couldn't help but ask.
"Frost Leaf Vine Guiding Agent," Louis answered casually, still focused on observing the few red figures slowly wriggling between the crevices of the rocks ahead.
"Frost Leaf Vine?" Emily repeated in a low voice, "How come I've never heard of it?"
"That's normal." Louis's lips curved slightly, a hint of self-assuredness appearing in his eyes.
"A rare chill-type vine from the Northern Wilderness, often found clinging to icy cliffs, secreting a sticky blue sap with a piercingly cold scent when mature. I had some people collect a batch for experiments, and after refining, it was made into this guiding agent."
