When modern young man Lin Yu bound to the historical live broadcast system, he became a lone traveler traveling through time and space. From the beacon fire at the end of Qin Dynasty to the poetry banquet in the prosperous Tang Dynasty, and then to the dangerous city of Jingkang, he was not only a broadcaster of history, but also a variable of history. Every live interaction creates a storm of butterflies; every intervention decision encounters backlash from time and space corrections. This is a game against time, and it is also a pious dialogue about history - the camera has been turned on, and you and I are both witnesses.
