They called him trash—until he started treating the Dao like a Dataset. When demons slaughter his new family, computer scientist Johan—now reborn as Yu Han—survives by pure wit. He gains access to the mysterious system that all cultivators use to defy the heavens. The Dao. But it won’t be enough. Betrayed, stripped of everything but his clothes and a worthless booklet, his only way to live is to join the prestigious immortal sect recruiting new disciples. But before he can even step into the sect, he slaps the faces of two powerful young masters. Yu Han should have no path forward. But in his past life, he wasn't just any programmer—he was a corporate warfare consultant who wrote not only code but obituaries, treating business rivals like lines of bad code to be mercilessly eliminated. Trash talent? He'll code his own. Death feuds with young masters? Mere bugs to debug. No money? Just another optimisation problem. Watch this blood-thirsty fatty sprint toward immortality, bringing algorithms to sword fights and treating cultivation like a hostile takeover! First though, he needs to lose some weight. Start Reading from Chapter 1 What to expect: - Weak to Strong. Poor to Rich. Fat to Fit! - Earned progression through blood, sweat, grit, and lots of devious planning. - Xianxia with a LitRPG twist. All cultivators have access to the system. It isn't the MC's unique cheat. - No Harem -Third Person POV, with a 99% MC focus -Warning: Sensitive Content. It's NOT a grim dark story. But there will be dark elements (there are a few hard chapters near the beginning of the story). [Participant in the Royal Road Writathon challenge]
