What Kind of Collecting Habit Do I Call a Copy Collector?

I, Qin Xiao, am a professional copy collector. Originally I just wanted to study in graduate school quietly and look for my missing mentor. Unexpectedly, I stepped into the infinite flow, study room, amusement park, weird apartment... All the supernatural spaces, large and small, were sealed into his object pockets. The yellowed test paper can set the rules of the examination room, the music box can create a memory maze, and a key can make people "invisible" in place. I thought this would be it for the rest of my life, but I unexpectedly discovered a shocking secret from twenty years ago, and met another version of myself in the mirror. Good guy, you worked with me to collect it for a long time, but in the end, you even became a collection?
