Wang Chuan, a forty-year-old financial tycoon and founder of Yuchuan Capital, finds himself inexplicably reborn into his twenty-year-old body in the summer of 2004. As a fourth-year clinical medicine student at Jiangcheng University, he retains the memories of his past life, including his medical expertise and future financial foresight. Unlike his previous life where he struggled, this time he aims to navigate the world with a calm, calculated approach, leveraging his knowledge of stock markets and medical diagnostics to secure a prosperous future.

Upon waking, he is immediately thrust into a chaotic scene where a fellow student misdiagnoses a man suffering from hypoglycemia as having a heart attack. Wang Chuan steps in, utilizing a mysterious 'Clinical Medical Insight' ability that displays vital signs and diagnostic labels above people's heads. As he corrects the error and saves the man, he re-encounters key figures from his past, including his ex-wife, the powerful Xiao Yuchu, and the sweet nurse Lu Na.

Now, he must balance his medical studies with his secret ambition to build a financial empire, all while avoiding the pitfalls that led to his previous demise.
