"Eye of Darkness, open!"
In front of Han's peerless dark vision, nothing could hide.
The snakes hidden in the tree were like white ropes in Han's eyes. The birds flying in the air were more like white dots flying further and further away.
Under the Eye of Darkness, the world became black and white. Living creatures were emanating a white aura, and the lifeless wood, grass, and rocks were all black.
There was just one difference, and that were the espers. In Han's eyes, Black Tower and Faint Blue were colorful. Black Tower's zero-degree brain region was dirt yellow, maybe because power descent espers appeared this color under the eye of darkness.
Faint Blue's zero-degree brain region was colorless, maybe also because of Faint Blue's super power's attribute.
And their bodies, there were obvious meridians present, and the flowing aura in the meridians was blue, representative of the source energy.
