(Full Episode) Poor Guy Didn't Expect His Girlfriend to Cheat on Him with a Rich Second Generation, Gets Humiliated, Then Binds to a Sign-in System, And Gets Rewards for Signing In!

Lin Chen receives 100% ownership of Ming Yang Resort and Spa from his daily sign-in. He takes Chen Ziruo and Liu Lili to the resort, where an old wishing tree that had been withered for two years suddenly comes back to life. Lin Chen quickly uncovers corrupt practices by the resort's manager, Li Chunlai, who had been exorbitantly spending company funds. Lin Chen fires Li Chunlai and his entire management team, implementing a full audit and bringing in Liu Lili's capable friend Yanyan Liu as the new general manager, further consolidating his control and expanding his influence.

Lin Chen is dumped by his girlfriend Ying Ying for giving her a 'stupid Chinese machine' for her birthday. Ying Ying, now dating Zhao Tianqiao, flaunts a $50,000 Cartier ring, claiming Zhao bought it for her, and mocks Lin Chen, suggesting he could be a security guard at Zhao's company in the Golden Resources Mansion. Unknown to her, Lin Chen's 'Sign-in System' activates, granting him ownership of the Golden Resources Commercial Building and Street, a property worth over 10 billion dollars with annual rental income in the hundreds of millions. He is instructed to sign documents to finalize the transfer and collect rent.

Lin Chen arrives at the Golden Resources Mansion to sign the property documents and sees Ying Ying and Zhao Tianqiao again. Ying Ying mistakenly believes Lin Chen is still pursuing her or applying for a security guard position. Lin Chen reveals he is there to collect rent, which Zhao scoffs at, stating his office alone costs a million dollars a month. Zhao orders security to remove Lin Chen, but the property manager, Mr. Wu, arrives and apologizes to Lin Chen, revealing that Lin Chen is the new owner of the entire Golden Resources Mansion. Zhao and Ying Ying are shocked, and Lin Chen orders the Zhao family's company, Ankang Technology, to be evicted for rent arrears.

Lin Chen signs in again and acquires the freehold of Huijin Mansion, a building across the street from Golden Resources Mansion. The system also grants him a five-star personal secretary, Chen Ziruo, a highly capable woman with a double master's degree from Cambridge. Ziruo efficiently handles the paperwork for Huijin Mansion. Meanwhile, Zhao Tianqiao and his father, having been evicted from Golden Resources Mansion, attempt to move Ankang Technology into Huijin Mansion, boasting about the cheaper rent and hoping to poach tenants from Lin Chen's other building.

Zhao Tianqiao encounters Lin Chen again and smugly tells him that Ankang Technology has moved to Huijin Mansion. Lin Chen, with Chen Ziruo by his side, reveals that he also owns Huijin Mansion, shocking Zhao and his father. Ziruo informs them that their attempt to negotiate lower rent with the previous owner is invalid, and Lin Chen, as the new owner, agrees to rent to them but at a triple increase in rent. Humiliated, Zhao and his father are forced to leave, as Lin Chen demonstrates his decisive business acumen.

Lin Chen signs in and receives a limited-edition customized Ferrari with a special license plate. He goes to pick it up and gives a lift to Liu Lili, a shop assistant who has sprained her ankle. At the dealership, the staff treat Lin Chen with extreme deference, recognizing his vast wealth through his car and the 'China A88888' license plate, which is rumored to belong to a wealthy individual known for owning major properties. Lili is stunned to realize Lin Chen's true identity, and he later helps her deal with an aggressive suitor named Fang Lin.

Fang Lin, Zhao Tianqiao's cousin and a self-proclaimed 'young owner of Junzheng Life,' harasses Liu Lili and openly mocks Lin Chen, calling him a 'loser' and flaunting his new Mercedes. Lin Chen reveals the Ferrari is his, and when Fang Lin's father, Fang Yuanlong, arrives, he is informed that all their company's partnerships with companies in both Golden Resources Mansion and Huijin Mansion have been terminated. Fang Yuanlong, realizing Lin Chen's immense wealth and power, kneels and apologizes, begging for forgiveness. Lin Chen, after making Fang Lin apologize to Lili, forces Fang Yuanlong to sever all business ties with his son.

Lin Chen attends a charity auction with Chen Ziruo. At the auction, Lin Chen outbids Shen Lian, a playboy from Shen's Real Estate, for a valuable painting, paying 200 million dollars. Shen Lian, who previously disrespected Lin Chen and Ziruo, is stunned when Lin Chen's financial statements reveal a balance of over ten billion dollars. Liu Jinshan, a top 10 tycoon in Zhonghai, approaches Lin Chen to apologize for his nephew Fang Yuanlong's earlier behavior, confirming Lin Chen's rising status in the city's elite circles. Lin Chen later gifts the valuable painting to Ziruo, who appreciates its artistic merit.

Lin Chen returns home for the Mid-Autumn Festival, driving a 'regular' Mercedes Benz. His old neighbors initially dismiss him as a mere driver, while his parents also mistakenly believe he's still struggling. His old friend Ye Guobao, now Vice President of Yuanlong Games, boasts about his success and condescendingly offers Lin Chen a security guard job. Lin Chen quietly reveals his true standing by having Ye Guobao's superior confirm that Lin Chen is the major shareholder and actual boss of Yuanlong Games. Ye Guobao and his father are deeply humiliated, and Ye Guobao is made to 'clean toilets for a month' as a lesson.

Lin Chen's uncle, Lin Jianguo, is being pressured by a local bully, Zhao Lin, to sell his house for a paltry sum. Zhao Lin claims his backer is Deng Changming, director of the M1NT Club. Lin Chen, who owns 80% of M1NT, confronts Zhao Lin, who, along with his uncle Deng Changming, quickly realizes Lin Chen's immense power. Lin Chen forces Zhao Lin to buy his uncle's house for 5 million dollars and then pay an additional 1 million dollars in compensation, ensuring his uncle's financial security and teaching Zhao Lin a harsh lesson.

Lin Chen uses a 'stock return card' from his system, investing 100 million dollars in 'Summer Technology,' a company on the verge of delisting, which the system predicts will increase by 5000%. Despite warnings from online stock experts and friends, Lin Chen proceeds. Summer Technology then announces a groundbreaking 4G communication technology and a military partnership, causing its stock to skyrocket. Lin Chen's bold move makes him a stock market sensation, earning him a place among 'The Three Young Men of China Sea,' alongside famous wealthy figures.

Huang Qing, envious of Lin Chen's new status as one of the 'Three Young Men of China Sea,' tries to insert himself as the 'fourth mystery man,' but is ridiculed by Lin Chen for his debts. In retaliation, Huang Qing orchestrates a smear campaign on Weibo, accusing Lin Chen of a chaotic private life and bad character. Lin Chen, leveraging his powerful network, mobilizes dozens of internet giants like Penguin and Beaver to collectively support him and expose Huang Qing's malicious intent. Huang Qing is quickly arrested for multiple criminal behaviors, demonstrating Lin Chen's swift and decisive response to attacks.

Shen Lian, Liu Si (Liu Jinshan's son), and Fang Yuanlong form an 'alliance' to seek revenge on Lin Chen. They plan a multi-pronged attack: Liu Si creates a pirated version of Lin Chen's popular game, 'Jedi Survival,' with the same name, and uses powerful marketing to accuse Lin Chen of plagiarism. Shen Lian poaches top streamers from Lin Chen's 'Fighting Shark Live' to 'Cat's Teeth Live,' while Fang Yuanlong, using his connections, halts construction on Lin Chen's Ming Yang Villa project. The combined attacks cause significant financial losses for Lin Chen's companies.

Lin Chen remains calm amidst the attacks, deciding to target the Liu Group, the leader and only listed company in the 'alliance.' He mobilizes 10 billion dollars in cash from Jun Yao Capital (which he also acquired through the system) to short Liu's Group, exposing their financial fraud and the fake data of their pirated game. Financial institutions withdraw loans, partners cancel contracts, and their game is delisted. Lin Chen acquires Liu's remaining assets, effectively crushing their company and alliance. He then uses Jun Yao Capital to execute a hostile takeover of 'Cat's Teeth Live,' exposing their fraudulent practices and signing contracts, warning them of severe consequences for their betrayal. With his enemies defeated and new companies acquired, Lin Chen's wealth skyrockets, making him the world's richest man and enabling him to pursue his dream of Mars colonization.
