Countdown: Humanity's struggle to survive against yesterday

"Do you remember what you did yesterday?" The world suddenly rewinds to yesterday, and humanity never sees a tomorrow again. The laws of physics remain unchanged, human memory continues, but leftover food returns to the refrigerator, used toilet paper returns to its original thickness, and the dead are even resurrected… Jiang Ning, a former sleep researcher, lived a muddled life after his wife's death. When the world rewinds for the fifth time, he is forcibly notified by his smart TV, seeing hope for his wife's resurrection and deciding to step out of the shadows. However, when he returns to society, he is surprised to find that he has undergone a mutation, making him independent of the world and unable to participate in the rewind. From then on, he is like an orphan trapped in the cracks of time, walking in a world where everyone is flowing backwards. This is a story of survival against "yesterday." If you don't remember what happened yesterday, it doesn't matter! After all, yesterday has forgotten you too!
