I Was Hounded by Debt Collectors from the Start, but the System Says I Must Smile as I Rise

As rifts opened across the globe, the spiritual qi revival brought humanity not the benefits of evolution, but a brutal reshaping of the class system. Lin Xiao, a young man from society's lowest rung, was beaten by debt collectors over his loan-shark debts. By chance, he activated the Pain-for-Profit System from the depths of a rift. Its sole core rule was that whenever he took a hit, he had to maintain a standard customer-service smile. The brighter his smile, the greater his defense bonus and the more strength he could convert. To raise the astronomical medical fees for his younger sister Lin Miao's supposed "soul exhaustion syndrome," Lin Xiao signed away his freedom to the Wailing Live platform, becoming the world's first professional pain-tolerance streamer. On camera, monsters tore into him and powerful people humiliated him, yet he always wore a sunny smile that sent chills down viewers' spines, quickly becoming an online sensation. What he didn't know was that the sister he treasured was actually a supreme ruler on the other side of the rift. She watched his streams while snacking, all the while complaining that her brother didn't look cool enough when he got beaten up. As Lin Xiao approached the pinnacle of power, he discovered that the System was actually part of a scheme by the rift's gods to harvest humanity's "smiles of despair." Before he completely lost his genuine emotions, he would have to use that fake smile to tear away the gods' hypocritical masks.
