66 Chapter 66: The Hidden Territory - The Netherworld

"Black Mountain?!"

Feng Qing'an, who was still left with some energy despite being greatly overwhelmed by the feedback force, could therefore feel the agony Black Mountain was experiencing at this moment.

Suffering myriad stabs and slashes, undergoing bone-shattering pain

All these could not describe the torment that Black Mountain was enduring, and he could feel how hard it was for it to make even a single wail of pain.

Under the force of the Shedding Mortality Pill, its muscles, skin, bones, blood, and even its soul were undergoing intense and rapid changes. Its body was being crushed and then reshaped in the process.

A mortal body ascending to the realm of the great demons in one step, this was the pain it had to endure.

"Hold on!"

All Feng Qing'an could provide at this moment was moral support. He couldn't alleviate the pain brought about by this transformation. This was a metamorphosis that could only be endured through the will of the Guardian Beast itself.
