Gu Zhao, a senior "time travel picket" of the Time and Space Administration, thought that his life would only involve tracking down careless tourists who accidentally brought their smartphones to the Tang Dynasty. However, in an unexpected mission, he ran into a "time fugitive" from the Ming Dynasty - an ancient scholar who claimed to be able to write love letters. Gu Zhao only wanted to get a promotion and a salary increase, but his tasks became more and more outrageous: the scholar not only knew nothing about modern technology, but also launched an "ancient pursuit" of Gu Zhao. Even the AI in the bureau was amused by his poems. The two of them battled wits and bickered in the gap between time and space, and by mistake, Gu Zhao discovered that he was not the only one on the run - it turned out that everyone had a past that they were afraid to face. Time and space are intertwined, and love may be just a misoperation, but Gu Zhao decided: Even if he travels through a thousand years, he will fix the bugs in his life with a smile. If you want to see a time-space love that doesn't follow the routine, come here and travel through time and space with Gu Zhao, tinker with things, and fall in love by the way.
