[Mental illness + yandere + multiple heroines + comedy + System] “System successfully bound! Would the Host like treatment for mental illness?” “You're the one who's sick! Your whole family is sick!” “Host, you really do have a mental illness. Would you like to receive treatment?” “I don't! If you don't believe me, ask my mom. Mom! Tell me, do I have a mental illness?” “Be good, I'm your older sister, not your mom~” “Really? Then why are you a woman? My mom is a woman, and you're a woman too, so why aren't you my mom?” System: “…” There's no hope for this guy. He really is sick! In the year 3866, the entire world had gained control over supernatural powers, and people everywhere awakened abilities of varying ranks. Only one person failed to awaken: the protagonist, Ye Xiu, who suffered from a mild mental illness. Fortunately, there was a way out. Ye Xiu had an extraordinary talent for ancient martial arts and was bound to the Ancient Martial Arts System. The Ancient Martial Arts System had only one goal: to turn Ye Xiu into a grandmaster of ancient martial arts who could crush every ability user! The unfortunate thing was that Ye Xiu was mentally ill! Even more unfortunate, the guy didn't even think he was mentally ill!
