The first piece of information to stand out was that the Mutated Battlefield wasn't a battlefield at all. The competition among Sects had turned it into something vaguely worthy of that name, but the place had nothing to do with a past battle or anything similar.
Instead, the Mutated part of that name was perfectly fitting. Apparently, the forbidden zone didn't feature ordinary wolves, rats, snakes, or bats. The magical beasts there had twisted beyond their species, and that made them valuable.
Just like cultivators, magical beasts developed cores. Liam didn't know the specifics, but he had read that they were inferior, yet still valuable. The same went for many parts of those creatures since their Qi-enhanced properties made them ideal for inscriptions.
Obviously, the stronger the magical beast, the more valuable it would be, and the same went for its uniqueness. The twisted animals in the Mutated Battlefield were extremely rare, making collecting their parts worthwhile.
