Hades, the Urban Legend - Chapter 283 - 284:

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]

Yun Luo Feng, Hua Xia Medicial School’s genius, died from an accident and her soul attached to Long Xia mainland’s General family’s useless eldest miss.

This waste of an eldest miss not only can’t read or practice martial arts, but is big chested, has no brain, is arrogant and self-willed.

Since having the crown prince as a perfect fiance isn’t enough, she actually snatched a pretty boy in public, leading to the crown prince annulling the marriage.

But she couldn’t stand the annulment and hanged herself.

Opening her eyes again, she is no longer the previous useless miss.

She contracted a God’s puppet and carries a spiritual space. With wonderful hands that can rejuvenate and medical skills that overturn the world!

Both the the royal descendants and nobles above and the merchants below, all compete to curry her favor. Even His Royal Highness, the crown prince,who previously broke the engagement, came knocking on the door wanting to reconcile.

In regard to this, a mysterious man finally couldn’t endure: “Whoever dares to come and harass my woman, let them come but never return!”

I am the best when it comes to taking divergent paths. With just a flip of my hand, I shall take the path less commonly travelled. I search far and wide, only to find myself unbeatable and unrivaled. So now I ask, who else can match my awesomeness?

Acting tough is second nature to me and I am a lone wolf.

The road is long and winding but I shan’t feel lonely as long as I am able to act tough!

Life and death bore me and I do whatever I deem fit.

“Young man, way back when I started acting tough, you were still learning how to put on your underpants!” Xu Que thus decided to take the path of acting tough. He decided to act tough every single god-damned day. If he wasn’t acting tough, he was scheming for the best way to act tough!
