When the US-China tariff war crushes his family's import empire overnight, 25-year-old Lucas Zhang loses everything — his fortune, his reputation, and his father to a stress-induced heart attack. Penniless and drowning in debt, he discovers a mysterious System embedded in an old trading ledger that his father left behind. The System gives him one impossible power: the ability to see market movements, trade routes, and political negotiations 72 hours before they happen. Armed with this supernatural edge, Lucas begins rebuilding from the ashes of a collapsed warehouse in Los Angeles. But the road back is paved with enemies — a ruthless Wall Street hedge fund manager who shorted his family's company, a Chinese competitor who stole his father's suppliers, and a shadowy government agent who knows about the System and wants it for national security. Set against the real backdrop of the 2025 Geneva tariff truce — where duties plummeted from 125% to 10% in a historic 90-day deal — Lucas must navigate treacherous trade corridors, manipulate global supply chains, and outmaneuver billionaires who play with nations as chess pieces. Every deal is a battle. Every alliance is temporary. And the System has its own secrets — secrets that could make Lucas the most powerful trader alive, or destroy him faster than any tariff ever could.
