In the 21st century, Wei Ci, a civil engineer, became a prisoner of the Qin Dynasty for repairing the imperial mausoleum. What's even more deceptive is that the supervisor threatened that if the construction period was delayed, everyone would be buried alive! The foreman collapsed on the ground and cried loudly, while hundreds of people knelt down and begged the First Emperor for mercy. Wei Ci silently took out the mobile phone with 89% battery left in his trouser pocket and clicked on "National Treasure·Qin Shihuang's Mausoleum Special". The moment the holographic projection lit up, all the officials exclaimed, "The magical magic is manifested" - he used satellite maps to locate the precise coordinates of the emperor's tomb, and used BIM modeling to rearrange the drainage channels. What's even more amazing is that the "Age of Empires" game on his mobile phone was printed with a complete set of lost Qin Nu manufacturing drawings! Three days later, an urgent messenger came from Xianyang Palace: the emperor came to inspect the construction site in person - but Wei Ci waved his cell phone and looked up at the stars: "Don't worry, wait for my next water conservancy project simulator."
