Zhou Yuan was reborn. He returned to the autumn of 2018, to a time when there was still a chance to make things right. Military training, the cafeteria, the camphor trees by the track. Lin Wanning handing him a bandage, Bai You saying, "It's too noisy," Su Xiaotang crying as she named a tender shoot, Xiong Lei grinning foolishly and saying, "Brother Yuan, I think I'm starting to get it." The world was turning bad, but they didn't know it yet. The red moon would rise in three months. Rifts would appear, strange beasts would pour through, people would die, awaken, or turn into monsters. But before that, they still had a brief time when they could sit together by the track and talk.
