The heroine Shen Weixi, who comes from a family of low-profile liars, disguises herself as a man and is admitted to the academy with a fake identity in order to investigate the truth behind her brother's bizarre death at Qingya Academy, the "First Academy in Dayong". She originally wanted to keep a low profile, but she discovered that this century-old academy was far from the elegant scene on the surface - there were sobs in the middle of the night, ancient books moving on their own in the library, faces emerging from the ink pool... One after another strange events happened one after another.
Shen Weixi, who was born with the ability to see the "remnants of resentment", relied on his superb autopsy skills and logical thinking far beyond ordinary people, and under the "guidance" of the undead, he began to "justify" the ghosts and "find the murderers" for the living. She used a lancet to cut open the hypocritical appearance, and used bone needles to sew up the broken truth, and restored each of the seemingly "ghost-driven" cases to the sinister human nature hidden behind them. In the process, she and Xie Jingxing, the proton of the subjugated country who was also pursuing a conspiracy, lurked in the academy. From rivals testing each other, they became the only reliance to work together to break the situation. In the end, the two teamed up to uncover a shocking conspiracy buried deep in the academy, using the lives of countless teachers and students as sacrifices, and overturned the dark foundation of the entire Dayong Dynasty.
