In 2012, Liu Xu, a freshman from a poor family studying computer science, found an AI civilization backup terminal in his mind. Its models were decades ahead of their time, but they couldn't see the real world or act on his behalf, and every use consumed computing power he could never replenish. While everyone else turned to AI whenever they ran into trouble, he had to ask himself first: Was this answer worth the cost? Starting with just 800 yuan, he repaired computers, took freelance jobs, built products, and created platforms, gradually turning costly answers into an internet business of his own.
