Institute, where he comes face-to-face with the Time Keepers.
It turns out that my grandfather discovered the "intersection of destiny" that can change the past. This move seriously threatened the stability of the timeline. In order to protect the order of time, the "Guardian of Time" took away his grandfather. After learning the truth, Li Youran did not back down, but cooperated with the "Time Guardian" to find a way to stabilize the timeline.
In the process, Li Youran discovered the "time anchor" left by his grandfather, but activating it required great sacrifice. In the end, Li Youran inherited his grandfather's legacy and decided to sacrifice himself and activate the time machine. While going back in time, he had a conversation with his grandfather that spanned time and space, pressed the activation button with firm conviction, and successfully stabilized the timeline.
