Ruler of the Secret Realm: My Prompter Is Incredible

My name is Lu Chen, the captain of Nan No. 7 Lieutenant Colonel. Three years ago, the mysterious realm invaded reality, and deadly copies were everywhere in the city. The mother disappeared from the copy, leaving only a notebook filled with clues. Now that the second year of high school has begun, the school beauty Ye Zhaoran appears, and she actually has the same symbols as those in the notes. Weird rules begin to engulf the campus, and survival can only depend on breaking the contradictory rules. I accidentally got a prompter that can reversely deduce the loopholes in the rules. It allowed me to see through the deadlock between "no lying" and "no telling the truth." Others are struggling in fear, but I have figured out the rhythm of survival. While others are still running for their lives, I am gradually uncovering the truth about the mysterious world and the disappearance of my parents.
