Cultural relic restorer Shen Nanxing holds an AR lens that can see through millennia-old cracks in ancient buildings, but cannot solve the mystery of his life experience; genius architect Lu Shiqian reshapes the city with "ruin aesthetics", and the burn tattoo on his lower back hides the shocking conspiracy of his father who committed self-immolation after being wronged. When the restoration data was strangled by capital, an AR restoration of a Ming Dynasty mural made the two of them fight for their lives on a rainy night - she crashed into the cracks of his load-bearing wall to protect the traditional mortise and tenon joints, and he encoded the heartbeat frequency into the architectural drawings to preserve the truth. Reunited seven years later, the Zhou Group's blasting instructions were counted down in the live broadcast room. In the digital ruins, Shen Nanxing used blue and white cobalt to crack the code of his father's death, and Lu Shiqian used a braille relief to reopen the Memory Museum. When the mortise and tenon joints of the ancient building bite the AR code, the heartbeat across time and space becomes the most lethal repair agent - they want to use the fire data from twenty years ago to rebuild a breathing city under the iron heel of capital.
