Inside the cave entrance, it was pitch-dark, yet Mu Rufeng could still see clearly.
Mu Rufeng glanced at the porcelain bottle in his hand then noticed a sizable lump of flesh a bit further on.
Without hesitation, Mu Rufeng grabbed the flesh.
This flesh, upon being lifted, felt soft and squishy, and even twitched as if it were alive.
It even seemed to want to merge Mu Rufeng's hands into its walls, exhibiting a strong devouring nature.
Immediately, Mu Rufeng blocked the cave entrance with the flesh wall and cast the "Ghost Technique."
However, what surprised Mu Rufeng was that outside the flesh wall, it was completely impenetrable, sealed off.
Indeed, this flesh belonged to the Swallowing Sky Demon Whale, the dominator of the Dead Sea. How could his Level 8 "Ghost Technique" break through?
Still, there were no obstructions in this passage, and Mu Rufeng thoroughly investigated all around with ease.
