Shadow on the Pillow: Your Majesty, Don't Look Back

My father was the best head catcher in the capital, but he died under the "shadow of the pillow" in Yangxin Hall, leaving only half of a broken hairpin with the word "Liu" engraved on it. In order to find out the truth, I sneaked into the palace disguised as a palace maid and hid under the emperor's bed that night. I finally ran into that black shadow - it had a sweet smell mixed with rosemary, which was exactly the same as the smell next to my father's body. But I didn't expect that the always aloof emperor would have a birthmark with a hot seal on his chest; the seemingly hostile head of the Shang Palace Bureau would have my father's amulet hidden in his sleeve; and the woman in plain clothes who handed over a complete silver hairpin would have the same birthmark on the back of her neck as the carved pattern on the broken hairpin. When the secret passage led to the stage, the incense powder turned into a ghost, and the Luo family's token resonated with the Liu family's silver hairpin, I realized: what my father was investigating was not a murder case, but the Luo and Liu families' covenant to protect the millennium, and the dark shadow on the pillow was just a precursor to the loosening of the seal. On a night of seven stars, the resentment of the ancestral temple was about to be broken. I held the blood-stained silver hairpin and stood in front of the emperor - "I will guard what my father has protected for his whole life."
