Sign In: I Went from a Poor Boy to a Billionaire

22-Year-old Lin Chen is a poor boy who has just graduated. He lives in a 10-square-meter rental house and owes three months of rent. He relies on odd jobs on construction sites to make ends meet. He is also publicly humiliated by his money-worshiping girlfriend Su Qing and her rich second-generation new love. At the moment when his dignity was shattered, the "daily sign-in system" suddenly activated! Signed in at a milk tea shop, got 100,000 in cash, and dumped 20,000 to his ex-girlfriend on the spot to settle the past, which made the rich second generation speechless; returned to the rental house to sign in, and paid off the rent, which made the snobbish landlord change his face instantly; signed in at the construction site, gained advanced engineering management skills, and was invited by the project manager with a high salary; signed in on campus, and directly won the city center apartment, slapping the face of his classmates who laughed at him! From tens of millions of restaurant shares in Jiangcheng Commercial Center to an entire office building on the Bund in Shanghai; from walking in a Maybach, to controlling a listed company, to becoming a shareholder of a Wall Street investment bank - Lin Chen signs in every day, and the rewards are upgraded layer by layer. Faced with the counterattack of the second generation of rich people, the suppression of business families, and the attacks of overseas consortiums, he relied on the skills, resources, and connections gained through signing up to counterattack all the way, with assets exceeding one trillion yuan, and he also revealed the secret of the "Guardian of China" behind the system. A poor boy became the world's top tycoon by signing in every day, and he also shouldered the heavy responsibility of protecting the country's industry!
