Yan Shu, the super soldier numbered zero, woke up in the night and at the end of the railway track. His memory was like autumn water reflecting dead leaves, blurry and cold. He is no longer the blade of the ordnance factory, silently walking through the crowd, just to escape the endless orders and blood. The footsteps of the pursuers were as heavy as the dusk, and the eyes of the old comrades shone with unknown compassion and hunting. His motivation is no longer to survive, but to find meaning outside of himself - among the ruins of being deprived of his name and past, is there still a ray of wind that will stay for the unknown? Yan Shu's escape is not a run for freedom, but a double farewell to himself and the world. He is not only the last fallen leaf in the autumn wind, but also the echo that no one knows. Every step of escape is picking up and forgetting the fragments of human nature, until the final chapter returns to nothingness.
