Before graduating from university in 2023, Lin Xing had experienced this kind of time travel three times. Judging from these limited three experiences, he believed that the length of time he traveled back to the past should be related to the size of the danger.,After confirming the time, his heart was in turmoil, constantly thinking: "This time travel went back a year But my memories before time travel were clearly of myself lying down to sleep.",“I don't know either, it seems like some kind of temporal disturbance happened, affecting the location where the door opens. Wait... there's someone there, he encountered the natives of the mirror world.”。
