Age of Authority

When I woke up from my lunch break, I found that three months had been stolen from me. There are photos on my phone that I don't remember taking, keys in the drawer that I don't recognize, and cilantro in the refrigerator that I would never buy. People around me said that there was nothing unusual about me in the past three months. But I know that's not me. There is another "I" who used my body to live for three months! What is he investigating? What is he investigating? In order to find out the secrets on his body, I started to follow the traces he left. Then, a world I had never imagined slowly unfolded before my eyes. The people there have a power called "authority". Space, mind, sixth sense, history... Each kind of authority corresponds to the ability to subvert common sense. I'm just an ordinary person, but I can rely on my own strength to uncover the secrets about me step by step! … … Is this really the case?
