Devil's Eye Reborn - Shadow Angel Awakens

At the dawn of time, God created the earth in six days and rested on the seventh. During this period, the archangel Lucifer led a rebellion of one-third of heaven's angels against God, but they were ultimately defeated. As a result, these angels were subdued by God's immense power, had their wings broken, were stripped of their right to "eternal life," and were cast down to the mortal realm, becoming demons that feed on human desires and negative emotions.
'Devil's Eye' means the eyes of demons, and every demon must have at least one or more 'Devil's Eyes' on their body. Normally, the 'Devil's Eye' looks just like an ordinary eyeball, but when a demon activates its supernatural powers, the pupil of the 'Devil's Eye' is stimulated by demonic energy, turning crimson. The brighter the red of the pupil, the purer the demonic energy within the demon.
The protagonist, Bi Yongnuo, was naturally reclusive from a young age. One day, at the age of sixteen, a stranger forcibly implanted a 'Devil's Eye' in him, turning him into a demon. Over time, he gradually comes to realize that his destiny is inherently connected with all the demons in the world and the secret of the apocalypse...
