Ten Days Mystery Box

[No harem, no system, no cool writing routines, pure logic flow survival game] "If the truth is not found within ten days, everyone will be trapped in a death loop forever." After a strange rainstorm, seven strangers woke up in an abandoned "time museum". There are ten mysterious exhibits on display in the museum: a blood-stained pocket watch, a broken hourglass, a blackboard filled with formulas... Each exhibit is related to an unsolved case. There are only two rules: 1. Solve the puzzle of one exhibit every day, otherwise a random person will die; 2. On the tenth day, if the identity of the "master" is not revealed, all members will be annihilated. Genius criminal profiler Jiang Lin discovered that the flow of time here is different from that in the outside world - every day that passes, the real world goes back one year. What's even more frightening is that there is a "resetter" hidden among the seven: he knows everyone's past and tries to tamper with history. When the truth becomes a variable and trust becomes a bargaining chip, can they tear apart this century-old conspiracy in the ten-day countdown?
