The mantis monster with a human face let out a scream, and as its human-like face opened its mouth to vomit, a jet-black poisonous breath, as dark as ink, rolled towards the White Ghost Emperor.
The most terrifying aspect of the mantis monster with a human face wasn't its bladed foot attacks, it was the Hundred-Insect Gu Poison it spewed from its mouth. This poison was a convergence of venom from a hundred different poisonous insects. Even a cultivator at the Great Perfection of Foundation Establishment Stage, if sprayed with it even once, would have their Protective Body Aura collapse, be afflicted with a strange poison, and experience excruciating pain.
The White Ghost Emperor also split its mouth open to vomit out a pitch-black ghastly breath that intertwined with the poisonous breath, causing both to collapse and neutralize each other.
As the White Ghost Emperor and the mantis monster fought, the trees around them began to wither rapidly.
