At 48, the down-and-out doctor Luo Mingyu watches helplessly as his 18-year-old daughter clutches her second-tier university acceptance letter and dies of a brainstem glioma beside his mahjong table.
After coughing up blood and dying, he somehow travels straight back to 2007 in his broken 48-year-old body, with a head of white hair and cirrhosis!
Through a shop window, he sees the 27-year-old himself on television, an arrogant prodigy at the provincial hospital. This is the younger version of him, before a medical accident made him fall from grace and before he wrecked his marriage and family!
To change the fate of his wife and daughter, he assumes the name "Luo Shoudao." Clamping his trembling right wrist with his left hand, he earns his first fortune writing catchy mobile ringtones, then takes the university entrance exam as an older adult and scores an astonishing 717, becoming the province's top science student. He fights his way into Xiangnan Medical University and becomes his own 27-year-old self's first-year "junior fellow"!
In the lab, his 27-year-old doctoral mentor looks down his nose at everyone, caring only about data for top journals and exorbitantly priced imported supplies.
His 48-year-old first-year junior shows up with an enamel mug and uses practical tricks like "scooping ash from a honeycomb-coal stove" and "jacking up an old house's roof beam." Again and again, he turns the tide in the operating room, grinding his arrogant younger self into the dirt!
He meant to shield his younger self from every obvious and hidden threat before his cirrhosis finally took its toll, while saving enough money to provide for the daughter who had yet to be born.
But he never expected industry leaders and medical luminaries to mistake him for a hidden master descended from the heavens, the one who could hold the world steady. And when he finally collapses under the operating lights, blood soaking through his mask, 27-year-old Luo Mingyu reads the bloodstained diary and completely loses his mind...
