"Phew, phew, phew..."
Lin Zhiluo closed his eyes, taking deep breaths as he sensed his surroundings.
The muscles that had been tensed across his body and the veins bulging beneath his skin gradually relaxed under his control.
This was precisely why he had not rushed to the top to search for the Corpse Ancestor, instead waiting by the entrance all this time.
He was doing his best to adapt to a strange energy within the Peak of the Immortal Kingdom!
The unknown beast hide had mentioned that the Peak of the Immortal Kingdom contained a strange energy derived from and created with Eternal Energy.
Within the Peak of the Immortal Kingdom, this strange energy served to suppress—or rather, test—those inside.
Other than Eternal Grade beings, every being that entered this place would be affected by this strange energy.
This strange energy would continuously suppress and affect their bodies, resulting in a series of negative effects such as reduced attributes and restricted movement.
Some beings with low attributes and insufficient abilities might even be directly suppressed to death by the strange energy after entering!
That was why Lin Zhiluo had not allowed Fuxi and Chiyou to enter the Peak of the Immortal Kingdom at the time.
Even with their strength, they would have had at least 30% of their base attributes weakened here.
Fuxi and Chiyou in that state would have had a hard time threatening the Corpse Ancestor. It would have been more worthwhile for them to intercept and kill more Mythical Grade Zombies in the Corpse Emperor Capital.
As for why neither the Corpse Ancestor nor Lin Zhiluo cared about the effects of the strange energy within the Peak of the Immortal Kingdom?
The answer was simple.
The Corpse Ancestor had simply become familiar with it through long practice.
