Xiao Chen is reborn to the day he won a physics competition, a chance for guaranteed admission to Tsinghua University. In his previous life, he sacrificed everything for his family's approval, only to be murdered by his adopted brother, Xiao Ming. This time, he vows to live for himself and not to please the ungrateful Xiao family.

Xiao Chen confronts his family, revealing their hypocrisy and the truth about his difficult upbringing. His parents, who always favored Xiao Ming, accuse him of cheating in the competition and demand he withdraw. He refuses and, after revealing his family's true colors, signs an agreement to sever all ties with them, promising to repay the 300,000 dollars they claim he owes.

Xiao Chen, now free, uses his knowledge from his past life to thrive. He helps Mr. Xiao, his former father, avoid a bad investment, earning his gratitude. He also encounters Song Ziyan, a kind classmate, who helps him find an apartment for his grandmother and becomes a close ally. He begins earning money through shrewd financial advice and a design consultation for Song Ziyan's eccentric family.

Song Ziyan helps Xiao Chen recover surveillance footage, which reveals Xiao Ming's deceit in blaming Xiao Chen for a broken vase and a stolen bracelet. Xiao Chen also advises Li Mingyu on stock investments, warning him about Northern Wood stock, which Xiao Qian, his sister, encourages Li Mingyu to invest in. This leads to friction as Xiao Qian's advice proves disastrous.

Xiao Chen continues to navigate his new life, enduring the Xiao family's attempts to manipulate him. He protects his grandmother from their scorn and exposes Xiao Ming's manipulative behavior to Song Ziyan. He also helps Officer Zhou, who previously aided him, by providing information that averts a tragedy for Li Yongyuan's restaurant.

Xiao Chen repays his debt to the Xiao family, solidifying his break from them. He proves his innocence regarding past accusations, exposing Xiao Ming's lies. His excellent performance in the city-wide physics exam solidifies his reputation, to the dismay of the Xiao family and some teachers, particularly Mr. Sun, who underestimated him.

Xiao Chen's business acumen shines as he advises Mr. Zhang on a crucial land investment, earning his trust and a share in the profits. He also partners with Li Mingyu to establish an investment company, leveraging his financial foresight. He continues to encounter the Xiao family's attempts to undermine him but remains resolute in his independence.

Xiao Chen's network expands as he attracts new allies, including Zhang Zi'ang, grandson of Mr. Zhang, who seeks his expertise in antiques. He also receives gifts and attention from various classmates, highlighting his growing popularity and influence. He uses his knowledge to expose a fake antique at an auction, further solidifying his reputation.

Xiao Chen's investments yield significant returns, allowing him to further invest in Li Mingyu's company. He confronts his family at a celebration for Xiao Ming, exposing his brother's fraudulent academic achievements and hypocrisy. Despite their attempts to discredit him, Xiao Chen stands firm, emphasizing their severed ties. He also learns more about his past connection with Su Muyu, revealing a story of a blood transfusion that inadvertently led to Xiao Ming taking credit.

Xiao Chen's strength and resourcefulness continue to develop. He deftly handles attempts by the Xiao family to exploit his connections and confronts Xiao Ming's continued manipulative behavior. He saves Li Yongyuan from a potentially fatal gas leak and continues to invest wisely. The video ends with Xiao Chen walking with Song Ziyan, looking towards a future filled with promise and genuine relationships.
