I've Already Conquered Immortality, and You Say You're a Western Doctor?

Centuries from now, medical maverick Mi Zixuan discovers cures for every deadly disease. Bored out of his mind, he decides to take on the one challenge Qin Shi Huang never beat: immortality! But the ideal is grand, while reality is harsh. Mi Zixuan ends up at the feet of the final boss and gets himself killed. Perhaps the Buddha, or maybe God himself, can’t bear to let Mi Zixuan die just like that. His soul is sent straight back several centuries, to the present day, where it inhabits the body of a medical college student who also happens to be named Mi Zixuan. Having fallen from rich, handsome heartthrob to a broke loser, Mi Zixuan is seriously unhappy. So he resolves to use the medical expertise from his previous life to become the best intern around, then the greatest, most badass doctor of the century!
