At the Break of Yesterday, I Went Back to the Past to Save the Future.

When Ye Jinyu opened his eyes and found himself standing in the classroom in 2009, he thought it was a dream. Until he saw the torn purple light streaks in the sky outside the window, until he discovered that he could "see" the structure of space, until someone in that world told him: You are both the past and the future; you are both here and there; you are both the savior and the saved. Dual identities of the past and future, life and death choices in multiple worlds. He must cross the barriers of space and break through the shackles of time in order to save all the people he loves before the cracks in time and space expand.
