Toaru Majutsu no Index - Volume 19, Epilogue: They Will Not Let It End a Tragedy. Brave_in_Hand.

Tang Nuan, the cannon fodder supporting female in a sweet pampering novel, woke up after an accident and decided to get rid of her fate after she foresaw her tragic future in advance. The first thing she did was to break off the engagement with her wealthy fiancé. She felt that she knew the plot in advance and also knew the secret of her fiancé Ye Shuyan’s mind-reading ability, so she would be able to quit the marriage smoothly. However, she did not expect Ye Shuyan’s mind-reading ability limited to a three-meter distance would be an exception to her.

Ye Shuyan, who has always been with Tang Nuan out of responsibility, found that his fiancée was completely different from what he imagined after he had the mind-reading skills. He developed a feeling of admiration, so he, who firmly did not want to break off the engagement, and Tang Nuan started a series of battles of wits and courage.

The two protagonists redeemed each other in the struggle between breaking off and not breaking off the engagement, facing their feelings sincerely, and reaping sweet love and marriage.

But this time, he has the ultimate cheat code—memories of the future.While other kids play with toys, Carlos hunts for divine legacies. Using his game knowledge, he performs an ancient ritual and steals a Demigod Mark from the thousand-year Sacred Oak—a power that should have remained hidden for decades.At 15, Carlos awakens as a Death Herald with broken stats that shouldn't be possible. Most Death Heralds are fragile summoners hiding behind weak skeletons. But Carlos combines his necromancy with stolen divine abilities, creating a hybrid build that turns him into an unstoppable force......[Skeleton Warrior has successfully evolved into Purple Thornblade Skeleton Guard!][Purple Thornblade Skeleton Guard has activated Bond: Glory of the Purple Thornblades!][Twelve Purple Thornblade Guards have formed an Undead Armored Knight Legion!].....His skeleton warriors aren't cannon fodder—they're elite undead legions enhanced beyond normal limits through secret evolution paths that took thousands of players years to discover.Every “coincidental” encounter is actually Carlos farming legendary opportunities. While his sister thinks he's just a lucky genius, Carlos systematically raids every hidden treasure, secret technique, and forgotten legacy he remembers from the game. Ancient bloodlines, divine artifacts, mystical cultivation methods—if it exists, he's taking it.With his infinitely evolving undead legion, Carlos set out on a path to rewrite destiny and become the supreme Death Herald legend.

Behind the calm smile lies a heart riddled with scars.Beneath the weight of fate burns an unyielding gaze.A body trapped in the abyss of despair—if it reaches out, can it grasp the light called hope?A soul locked upon the rack of destiny—if it prays sincerely, can it embrace the future called redemption?

I just want to be different, no one can guess what I want to do, the more mysterious the more powerful.
