Lin Jian, a trainee judge with the lowest performance in the underworld, was forced to take on an outrageous task: live broadcasting modern China to Qin Shihuang Yingzheng in parallel time and space. From then on, a sky curtain hung high over Xianyang Palace that only the emperor could see. The high-speed train is speeding, the aircraft carrier is breaking through the waves, the rice ears are like waves, and the sound of books is ringing. Ying Zheng's dream of being emperor forever was completely crushed, and a more blazing fire was rekindled in the ruins. He built schools, established buildings, and tried to drag the light of two thousand years later into his own era. Lin Jian just wanted to finish the KPIs quietly, but she didn't know that the video she posted casually was causing Da Qin's trajectory to soar into the unknown sea of stars, and also made the performance appraisal system of the underworld turn on the red light for the first time for "excessive changes in the process of human civilization."
