Cliff Mountain Range, amidst a cluster of mountains.
Teaching Institute Grand Elder Qingxuzi, carrying a long sword, arrived in a cavern covered in a vast expanse of Mysterious Runes.
The cavern had numerous branching paths, interconnected tunnels, a looped and tortuous layout, leading in all directions.
On the walls were patches of red runes, emitting a faint fluorescence.
However, this glow was suppressed by dense, dark energy.
The black mists, thin and wispy, lingered in every corner of the cavern, rolling and churning, dark and deep, with a bone-chilling coldness.
Moreover, countless bizarre and vicious-looking demon shadows hid within.
These were Killing Spirits formed from the fusion of impure energy and Killing Power, craving the blood of the living, choosing their prey to devour.
Yet Qingxuzi seemed unconcerned, gliding through the cavern as if it were second nature.
