A new work is released, welcome everyone to the story. Financial analyst Su Chan traveled through the Black Ruins and was in debt with three billion lives. After awakening the "Cicada Slough System", he turned his life into capital and planned a counterattack in the game of life and death. Use fake death to lure the enemy, use rotten bone grass to set up a trap, and backfire on the creditor to condense the best pure slough. When the Vulture Group collapsed and Ivy Capital surfaced, this debt merchant was preparing for a larger-scale life arbitrage - using three turbid sloughs to leverage the underground auction house and weaving a network of life and death with a rudimentary contract template. Under the neon lights and runes of the Black Ruins, a financial war with life as the goal has just begun. How will he play life and death arbitrage in the whirlpool of capital and life debt, and eventually become a black market capital boss?
