Chen Cheng discovers that turning thirty unlocks a transformative power: interest multiplies his wealth exponentially. Beginning with merely 3,000, his fortune escalates through staggering milestones—100,000, a million, ten million, surging past a hundred million. Each principal grows stronger, spawning cascading streams of passive income. As compound interest accelerates his riches, Chen Cheng realizes the impossible truth: his money transcends spending. No amount of consumption could deplete what he's accumulated. A lifetime of unlimited abundance stretches before him, wealth that eternally outpaces expenditure.
