When Lin Xia, a restorer of Huang murals, uncovered the covering layer from the Song Dynasty, he was involved in the bloody night of Chang'an in the fourth year of Zhenguan by the mysterious Sanskrit text. In front of the steps of the Yeting Palace, the blade of the future emperor Li Shimin was pressed against her neck, and the tortoise-shell star map glowed with a faint blue light in the palm of her hand - this was the code that disappeared in the mezzanine of the modern mural.
From a sinful slave to a female official of Si Baosi, she used nano-repair technology to restore the Persian Golden Chamber and used the carbon 14 dating method to expose the auspicious scam. However, she found that every cultural relic she restored was rewriting the truth of the "Yinghuo Shouxin" celestial phenomenon case. When the music score of the Western Regions concealed the map of the Turkic march, and the nine-luan golden hairpin contained the poison of the previous dynasty, the detector of the modern archaeological team actually pointed at the Xuanwu Gate at the same time as the sundial thousands of years ago.
The golden knife falling from the rift in time and space cut through the night, and Lin Xia finally understood the craftsman's code that spanned thousands of years deep in the mural: only by bringing the disappeared "Tiangong Pu" to light again can this life-and-death mystery that tears apart time and space be solved.
