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.,And the first thing he thought about was how to report this to the state.,After half a minute, Lin Xing panted and ran into the classroom.
