A class of creature born spontaneously from concentrated yin energy in the Netherworld Domain. They instinctively hunt humans and are nearly inexhaustible—killing one only leads to a replacement forming later from the same yin condensation.

Story context
Welcome to the Netherworld Domain, fellow Daoists—a pocket of sheer desperation where mana is dead, food is a luxury, and getting devoured by a yin-born beast is just another Tuesday. Chapter 591 punches the new-world reveal into high gear: Han Li gets a front-row seat to a life-or-death village defense against a Jiaozheng, a hulking Netherworld beast that belches black ice and bristles with razor needles. But the real treasure isn’t the green crystal they dig out of its skull—it’s the stark, brutal ecology the old elder lays out after the fight. This chapter isn’t just a monster hunt; it’s the Mortal Stream’s definitive guide to surviving a lawless, magic-stripped frontier.
Why it matters
Let’s be real—after a whole arc of treasure-hunting and backstabbing in the Void Heaven Palace, dropping Han Li into a mana-dead village with a shotgun-slinging militia feels like a genre switch. But this is peak Mortal Stream: the protagonist isn’t fighting with spells or treasures now; he’s watching, cataloging, and figuring out how to game a system where the currency is brute strength and the cost of failure is being eaten. The elder’s speech about “only the useful survive” isn’t just worldbuilding—it’s a mission brief. Han Li’s mind is already running the numbers on how to make himself indispensable, and we get to see him puzzle out the crystal mystery on top of it.
