It's Actually Not Easy Wanting to be a Supporting Male Lead - Chapter 9 part4

What is a Daoist Master? One that is imageless in ten directions and vanishes in the six paths; unrestrained by the three realms and the five elements.

Five hundred years after his death, Orion awakens in the aristocratic Reyes family—one of the five ruling houses of the Petrosyan Confederacy. With both his experience and trauma from another life, he must carve his own path in a world shaped by power, technology, and ruthless ambition.On a mission to Cerros-7, in the heart of a bustling market, a woman draped in tattered veils appears before him, her ember-like eyes burning with eerie intensity. With a grip as cold as death, she seizes his hand and whispers a prophecy that sends a chill down his spine:“The sky must fall for your star to rise,A veil of despair shrouds crimson skies.Through ash and ember, your brilliance softly flies,A light reborn where endless darkness lies.”As he navigates treacherous politics, genetic evolution, and a destiny far greater than himself, Orion must uncover the truth, before the prophecy becomes his undoing.Tags:[Reincarnation | Fantasy | Superpowers | Survival | System | Transmigration | Evolution]
