One-Click Upgrade: Super Decomposition System - Chapter 491

A 34-year-old NEET otaku, chased out from his house by his family, found that his life is reaching a dead end. He then recalled that his life could actually have been much better if he had made better choices in the past.

Just when he was at the point of regret, he saw a truck moving at fast speed, and three high schoolers in its path. Mustering all the strength he had, he tried to save them and ended getting run over by the truck, quickly ending his life.

The next time he opened his eyes, he is reincarnated to a world of sword and magic as Rudeus Greyrat. Born to a new world, a new life, Rudeus decided that, “This time, I’ll really live my life to the fullest with no regret!” Thus starts the journey of a man yearning to restart his life.

Molitia Clemence was born sickly.

She forgot to cover herself with a blanket and caught a cold. She woke up next to her husband after 10 days just because of a slight cold.

Molitia barely survived between the thin threads of life and death. When she opened her eyes, she noticed that her husband was somehow acting differently than usual…?!

“Have you eaten?” (Husband)

“Yes.” (Molitia)

“This is the belly of a person who ate?” (Husband)

He frowned as he stroked her flat lower abdomen. He held her wrist carefully, as if it would break. His voice rose.

“Why is your wrist so thin? Are you even human?” (Husband)

“That’s…” (Molitia)

“Butler!” (Husband)

The butler rushed to his angry voice, fidgeting with his wrists.

“Get me food for my wife to eat. Something that will help her stay healthy. Anything is fine.” (Husband)

Molitia’s mouth opened at her husband’s words, but no sound came out. ‘I just had a meal?’

In a world where its inhabitants can destroy a city wall single-handedly, the empress has a kirin as her pet, and the imperial palace of Great Xia has a pool containing a dragon. There is also a Sword Mountain where spirit swords occasionally leave in search of a master .

When the enigmatic and overpowered Kieran Drayke awakens in a foreign magical world after a sudden transmigration, he brings along a system unlike any this realm has ever known. The “Sovereign Architect System” doesn’t just make him invincible—it gives him the tools to build something far greater.But Kieran isn’t interested in world domination. At least, not in the usual way.Disillusioned by the world's surface-level glimmer and the rot beneath it, Kieran sets his sights on the forsaken—those discarded by society, lost in the shadows of nobility and corruption. From slums, war zones, and forgotten ruins, he gathers orphan girls of various races—elves, beastkin, humans, and more—each with untapped potential and pain behind their eyes.He trains them in secret. Guides them. Empowers them. Not as soldiers, but as a family. A hidden organization that operates behind the curtains, shaping the world while appearing as ordinary students at the prestigious Aetherion Magic Academy.Kieran himself? Just a carefree, slightly lazy transfer student with a penchant for sweets, sarcasm, and sneaking naps between classes—on the surface, at least.With a slow-burning plot that weaves magical worldbuilding, deep friendships, training arcs, casual comedy, and a cast of unforgettable girls who grow into queens of the unseen, Chronicles of the Hidden Crown explores what happens when an OP MC doesn’t conquer the world with brute force…But builds a legacy from its forgotten pieces.No betrayal. No forced drama. Just the steady rise of a secret kingdom in the shadows of a crumbling empire.
