Lu Yuan, a 21st century tech geek, accidentally triggered a quantum entanglement device while dismantling ancestral antiques and traveled to Chang'an City during the Zhenguan period. The incomplete data of the portable intelligent AI "Little Entropy" has become his only reliance against the paradox of time and space. When modern business logic encountered the feudal economic system, when nanomaterial technology collided with traditional handicraft industry, Lu Yuan set off a storm in the torrent of history. Not only does he want to build a business empire across the Silk Road, but he also wants to solve the mystery of time and space for thousands of years. Is this time traveling an accident or a sophisticated layout of future civilization?
