Time begins at zero and returns to zero. Two girls, Zero and Winter Ning, traveled through the timeline and got acquainted while working on tasks. However, Zero was severely injured during a mission and lost her memory. Winter Ning tried to wake them up but failed. It was a year later when they talked again. Zero was on the platform, and Winter Ning introduced herself again.
Because Zero's mistakes before amnesia caused time characters to constantly intersperse in different time periods, Zero did not know that the chaos in the timeline one year later was caused by her, and Zero wanted to correct everything.
But it is about to end the source, which is the body that carries time. This body escapes, resulting in gaps in each time period.
It can only be maintained by manpower. Some of the fast-developing weapons and items can come in handy, which greatly reduces manpower consumption. There are now three stations and each station has a different number. It has gradually stabilized. This is not a solution for a long time. We still have to find a body to escape.
Intent: Two girls travel through time and you find the source of everything
