Lin Yang, trying to save money for a dowry, moves into a shared apartment. He's immediately roped into catching mice and unexpectedly awakens a 'check-in' system, granting him the 'Capture Master' skill. This skill helps him impress his female housemates and earn free rent, making him realize the system's potential.
Lin Yang's next check-in leads him to Su's Antiques. He discovers his 'Capture Master' skill can also identify true antiques. While at an antique fair, he exposes a vendor's fake wares and buys a broken jade bracelet for a mere 20 yuan, much to the disbelief of Su Xiaoxiao, the owner of Su's Antiques. He later repairs it perfectly with his newly acquired 'God-level Repair' skill, revealing its true value and shocking everyone.
Lin Yang attempts to propose to his girlfriend, Xu Qingqing, but she publicly dumps him for Chu Mo, humiliating him. Later, he encounters Su Xiaoxiao and her friend Li Xin at a wrap party. Chu Mo, who is also there, forces Li Xin to drink. Lin Yang, now possessing the 'Immortal of Wine' skill, steps up to drink on Li Xin's behalf, challenging Chu Mo's associate in a high-stakes drinking contest and easily wins.
Lin Yang's repaired Qianlong imperial white jade bracelet is put up for auction. Chu Mo attempts to discredit Lin Yang by exposing his past as a deliveryman, but Lin Yang surprises everyone by acquiring the 'Angel's Tears' necklace for 2 billion yuan with a new black gold card. The bracelet then sells for 200 million, and a challenge to its authenticity by a rival antique appraiser is disproven, solidifying Lin Yang's skill and reputation.
Master Chen, a renowned restoration expert, invites Lin Yang to lecture at Kyoto University. Despite initial reluctance and questions about his background, Lin Yang accepts, prompted by a new system check-in. At the university, a Japanese restoration expert, Inoue Murakami, challenges the Chinese experts. Lin Yang steps forward to compete, demonstrating his exceptional skills and winning the challenge, further enhancing his reputation.
Lin Yang discovers that Tianheng Real Estate plans to demolish his hometown village. He learns that Tianheng Group is being acquired by a mysterious figure and, through a system check-in, receives 100% of Tianheng Group's shares, becoming its new chairman. He confronts Chu Mo, who is connected to the demolition. During a confrontation, Lin Yang's adoptive mother is injured by Chu Mo, revealing she is his birth mother due to a shared rare blood type and matching jade pendants.
Lin Yang's newfound position as chairman of Tianheng Group is immediately challenged by a coordinated stock market attack from the Chu and Lin families. With support from Su Xiaoxiao and Li Xin's families, and using his new 'Stock God' ability, Lin Yang strategically counters the attack. He not only defends Tianheng but also acquires controlling shares of both the Chu and Lin families, effectively taking over their businesses and solidifying his power. His mother, who is still recovering, recognizes him as her son.
After all the challenges and revelations, Lin Yang is considering what's next. His friends and family express their various desires for him to stay, for him to teach, or for him to continue helping them. He is now a powerful and wealthy individual, having found his birth family and established himself as a force to be reckoned with.
