Right outside the Thunder Valley before entering the trees that filled the horizon, dozens of people camped outside. Most had injuries on their body, some even with lost limbs. There were disciples from random sects and the rest being mercenaries.
Everybody there had one goal, which was to hunt Lightning Cats for their monster core, valuable and profound resources cultivators use to cultivate themselves.
Monster cores are what beasts use to cultivate and store their cultivation base. If a beast with a solid cultivation base died, they would have a chance of leaving behind a monster core with their remaining cultivation base inside that cultivators could use to cultivate themselves.
Monster cores could also be used to create powerful weapons that greatly boosts the strength of its wielder, hence its high demand and value.
