From Ghost-Brain Simulations to Martial Sage

Lin Xun transmigrates into a martial arts world and obtains the [Ghostbrain Deduction System]. To outsiders, he's an idiot who likes playing mind games with thin air. He's a lunatic who enjoys fighting insects. More than that, people mockingly call him "the Game Theory Guy." Only he knows that the enemies taking shape before his eyes are real. While everyone else practices stance work and spars with training dummies, Lin Xun is the only one throwing punches in the pouring rain, getting knocked flying by enemies in the air. You get the picture... Thanks to the Ghostbrain, Lin Xun seems like a madman to outsiders, but he always ranks first in the martial arts exams. In less than ten years, he claims the title of top martial arts scholar. He slays blood demons and battles powerful foes, eventually shedding his madman label and becoming known to all as the Martial Saint!
