My System Steals Cultivation Techniques

Transmigrated into the body of a condemned soldier, Cheng Cang wakes up exiled to a brutal borderland, where life is cheap and death is a daily certainty. Weak and targeted by ruthless veterans, he's just another victim in a land ravaged by wild beasts and barbarians. But just as despair sets in, a miraculous System awakens: the Cultivation Technique Extractor. It allows him to steal and instantly master any cultivation technique from anyone he comes near. His first extraction turns the tables on his tormentor, revealing an unimaginable path to power. Yet, with a massive barbarian invasion looming, can he extract enough strength from his unsuspecting comrades to become a hidden legend, or will his stolen power be too little, too late?
