The moment everyone stepped onto the fourth floor, a wave of heat mixed with a foul, rotting stench rushed toward them, making their stomachs churn. This was a giant lava cave more than a hundred zhang in diameter, its dark red walls embedded with various rusted instruments of torture—iron maidens, bed of nails, branding irons... Every single one was stained with dark brown, old blood.
In the center of the cave, a pool of blood about thirty zhang wide bubbled and churned, dense layers of white bones floating upon its surface. Even more horrifying was how these bones would suddenly assemble into complete skeletons, only to scatter apart the next second, emitting a hair-raising clicking sound.
"This floor tests willpower," said that hoarse voice, turning eerie and distorted as if echoing from the depths of hell. "Soak and temper yourselves in the blood pool for one hour; those who endure shall receive the 'Body-Tempering Spirit Liquid'. Those who fear... shall sink into the blood hell forever."
