[WARNING: MATURE EXPLICIT CONTENT R18]William Wade was once the world's most talented combat instructor feared by soldiers, respected by nobles, and admired by anyone who witnessed his impossible ability to turn even the weakest recruit into a battlefield legend.But after an unexpected betrayal ended his life, he awakens in a new world of magic, monsters, and prestigious academies where the strong rule without question.Reborn as a lowly “Zero-Class Instructor” at Astraea Combat Academy, William quickly learns he's supposed to be nothing more than a disposable assistant for elite students. His reputation? Trash. His starting stats? Pathetic. His salary? Insulting.But everything changes when a mysterious voice declares:“Harem Training System Activated.”The rules are simple and insane:Every time William mentors, trains, guides, assists, or even mate a girl with potential, he gains power. The stronger she becomes, the stronger he becomes. And the closer she grows to him, the faster his level skyrockets.Suddenly, William finds himself surrounded by extraordinary but dangerously flawed heroines where each girl is broken in her own way, each girl has talent capable of reshaping kingdoms. And each girl needs him more than they realize.As William trains them, he uncovers conspiracies within the academy, hidden wars between noble factions, and a shadowy group that may be connected to his betrayal in his past life.With every lesson, every breakthrough, and every bond formed, William grows stronger until the academy's weakest instructor becomes the world's most dangerous man.A legendary harem isn't something he wanted.It's something the world forced upon him.And he intends to train them into champions who can shake reality itself.---[IMMERSIVE SMUTS SCENES WITHOUT REPETITIVE!][NO NETORARE!
