I Was Charged at the Beginning, but the System Made Me Upgrade with a Smile

As rifts open across the globe, what the revival of spiritual energy brings to mankind is not evolutionary benefits, but cruel class reshaping. Lin Xiao, a young man from the bottom of society, was beaten up by debt collectors because he owed usurious loans, which accidentally activated the "painful business system" from the depths of the rift. The only core rule of this system is: you must maintain a standard professional smile when being attacked. The brighter the smile, the higher the defense bonus and power conversion. In order to raise the sky-high medical expenses for her sister Lin Miao's so-called "soul-depleting disease", Lin Xiao signed a contract of prostitution with the platform "Screaming Live" and became the world's first professional sadistic anchor. He was bitten by monsters and humiliated by strong men in front of the camera, but always maintained a creepy and sunny smile, and quickly became famous on the Internet. However, what he didn't know was that the sister he regarded as his treasure was actually the top dominator on the other side of the rift. She was eating snacks and watching his live broadcast, and at the same time she disliked the way her brother was being beaten. As Lin Xiao gradually approaches the peak of his power, he discovers that this system is actually a conspiracy of the Rift God to harvest mankind's "Laughter of Despair". He must use this fake smile to tear apart the God's hypocritical mask before he completely loses his true emotions.
