When "I", the fast-traveling mission user, was performing the last mission, the system unexpectedly crashed, causing me to be permanently trapped in a world of palace fighting. In the beginning, she is a hostage princess who was sent to an enemy country as a concubine. She is surrounded by dangers. After losing the system mall, mission guide, and golden fingers, I had to rely solely on the top skills I had honed in thousands of worlds—including but not limited to psychology, fighting skills, strategy, medicine and toxicology, etc.—To survive in PlayerUnknown's Battlegrounds. My goal is no longer to complete the task, but to live for myself, to play with the superior and hypocritical emperor, to crush all the open and secret arrows in the harem one by one, and finally to tear up the "script" of this world, from a chess piece to the only chess player, to become the uncrowned king of this deep palace and even the entire dynasty. The highlight of the plot is that the protagonist has no special powers or systematic help throughout the whole process. He relies solely on his IQ, experience and ruthless means to carry out dimensionality reduction attacks on various "classic characters" (White Lotus, Green Tea, Hypocrite, and Careerist) in the palace battle. The excitement is intensive and the pace is extremely fast.
