To rise from defeat; to revive amidst the dissipation.

As the vast oceans turn to dust and the thunder and lightning fade away,

That strand of spiritual mist once again approaches our great world.

With the shackles that bound our world now severed—

A whole new world of mystery and wonder awaits,

As we turn the corner…

The Sacred Ruins is a story set in a post-apocalyptic world. A world that has recovered to a state that is roughly equal to our own world in terms of technology and culture, although its ancient history remains largely unknown. The story begins during the post-graduation trip of our protagonist, where he discovers some ancient ruins and witnesses “the great change”, an upheaval that changed everything. The changing earth not only brought about new, unexplored landscape but also sparked the evolution of all organisms. Plants and animals started gaining sentience and some humans obtained unimaginable powers. The legends, myths, and tales of old seemed to have suddenly come to life as the earth entered a new era where beasts and men formed factions, explored new lands and ultimately struggled for supremacy.

We follow the MC as he grows from being an eccentric young man into a badass expert warrior while meeting other funny characters and forming brotherly bonds. We watch as he falls into just as much hilarious situations as he does perilous ones, all the while wondering and slowly discovering the mysteries of this world. Just why was the world destroyed in the first place? Who or what had triggered this earth-shattering “change”? What profundities lie behind the process of evolution?

Marcella Valemont was a villainess wrapped in silk and thorns.The alluring, selfish daughter of the High Priest, she was forced into a cold marriage with the Black-bellied Duke Berith Montclair. She longed for power and would stop at nothing to claim the crown, even if it meant seducing the incorruptible Crown Prince Lucian and clawing her way to the throne into becoming the Queen.Until it all burned.Her ruthless schemes led to betrayal, rebellion, and ruin-- an empire on its knees, a virtuous king destroyed, and a rebellion led by the man she discarded. Desperate and full of regret, she barters her life with the Duke to save Lucian.In an interesting turn of events, Marcella gets to go back in time to fix her wrongs, save the man who was ruined because of her and hopefully stop the bloodthirsty rebel Duke Berith.She finds herself reborn as her 18-year-old self with a chance for a do-over and vows to do better this time.But the past does not forget. Nor does the devil in her husband’s skin.Secrets long buried begin to surface, and Marcella discovers that her former husband is far more than he seems—a man cloaked in darkness, harboring a purpose that threatens everything she holds dear.They say second chances come with thorns and to fix the past, she must trust the devil who destroyed it.

When he opened his eyes he found that he had been reborn as an extra in a novel, which he finished reading yesterday. On top of that, he has become a student of the same battle academy, where the main plot will happen. Let's accompany Rio on his journey and find out where it leads us.“i will steal protagonists chances, as for what will happen to main plot if i do so? i don't care!” (Rio)*The book cover doesn't belongs to me if someone wants me to take it down please contact me directly.*(MC is selfish and cares most about himself, rather than following the main story he will follow his own will. and there's no harem too.so, if you like a hero of justice and a plot following type mc with a harem or something then this is not your cup of tea.)
