Su Qingyuan, who stayed up late to study for the postgraduate entrance examination, was accidentally bound to a mysterious system, and the system's mission actually pointed to an ancient tomb buried for thousands of years on the outskirts of the city. During the day, she is a cool academic leader who interacts on campus and in social circles. At night, she transforms into an eccentric explorer, uncovering the layers of mystery in the ancient tomb under the guidance of the system.
In an accident, she pretended to be a couple with the sunny Lu Zhaoyan, but she didn't know that he was the one who bound "the right girl" in the system's mouth. At the same time, psychologically twisted suitors are pressing forward step by step, ruffians are frequently obstructing her, and strange phenomena in the ancient tombs continue to spread to the city.
When switching between multi-faceted personalities, Su Qingyuan had to deal with the pressure of postgraduate entrance examinations, hide the secrets of the system, and discern the direction between true and false emotions. When the secrets of the ancient tomb are intertwined with modern conspiracies, can her "fake couple" relationship with Lu Zhaoyan emerge as true in the test of life and death? How does the code of the thousand-year-old tomb hide the truth that subverts cognition?
