Piggy

It looks like a Small White harmless Pig, but at the First time Ye Chuan saw it fighted against a 9 Headed Snake who was 1000 Years old and Bite is to Death. Ye Chuan Sneak attacked it but didnt kill it but Tame it. If it is a Ancient Beast or a Mutated Beasts is something even Ye Chuan doesnt know.
