Alex, the bottom-tier rookie in the ER, endures constant bullying from his senior mentors—until a near-death rescue awakens his hidden "Medical System," letting him see the root of any illness at a glance. To save Grandma Martha, the only person who ever showed him warmth in that cold hospital, Alex frantically cracks impossible surgical cases, humiliating arrogant medical authorities in crisis after crisis. Eventually he levels up, awakening the ultimate skill "Blind-Sight CT"—pulling the old woman back from death's door and ripping off the mask of the corrupt department head. He makes the entire hospital's elite bow to him, and lands a million-dollar offer from a top-tier conglomerate hospital, delivering the ultimate medical underdog triumph.
