The huge city of Tianshu is managed in layers. The heavenly beings in the floating city have absolute power, but the price is zero emotion. In the underground ruins, scavenger Lu Chenzhou accidentally activated two systems: simulation deduction, allowing him to see the outcome of every choice; and induction of corruption, forcing him to make a series of propositions. The first question: Kill the girl who blocked the knife for you, reward the perfect entropy crystal, and break through the bottleneck. Reject? The system will automatically deduct your emotional threshold - you have lost the perception of sadness after over-exerting it three times. Lu Chenzhou chose the third path. He deduced all the branches and found that the only way to save her was to make himself a public enemy of the entire giant city. So at the banquet of the six wealthy families in the floating city, in front of everyone, he poured a bottle of inferior purifying agent into the Holy Grail of Heavenly Beings. "Don't you want to know what it feels like to be 'fallen'?" He smiled, and there was no fear in his eyes. Tonight, the scavengers of the wasteland declare war on the clouds. And his most terrifying weapon is not prescience, but his heart that cares less and less about everything.
