The Evil Eye would subconsciously let out a roar every time it consumed an Essence Crystal. It quickly absorbed the energy of the Essence Crystals with the help of the Wizard Power and life force.
Slowly, its Essence Crystal expanded bit by bit and started to release bolts of red light. The mysterious pituitary gland also grew as it released waves of messy, yet increasingly powerful, ripples.
I might as well go all out now!
Seeing the transformation of the Evil Eye becoming more and more obvious, Yang Ling clenched his jaw, once again increasing the intensity of the energy he was injecting. The Evil Eye trembled, its six tentacles convulsing as it let out a suppressed howl. But at the same time, the rate of growth of its Essence Crystal and pituitary gland increased.
As the thick metallic stench of blood within the cave spread further away, faint weird sounds from far away began to draw nearer, as if some monster was rapidly approaching.
