Year 2048, China. This is an era where technology and tradition are intertwined in an unprecedented way. In the super city of Shanghai, maglev trains shuttle silently between the glass curtain walls of skyscrapers like a silver dragon, and holographic advertisements cast blurred light and shadow in the rainy night air. However, beneath these radiant appearances, the ancient inheritance and memories have not disappeared. They are like underground rivers buried deep in the ground, surging in unknown corners. Data has become the new oil, and control of "real history" has become the ultimate power. A giant company called "Tianqiong Technology", with its ubiquitous neural network and data analysis capabilities, almost monopolizes the right to define the future. But they know that if they want to truly control the future, they must completely decode the past.
