I can rewind time to prevent death

Yan Junze knew what his mother meant and replied, "Mom, you wouldn't like her." Li Man looked up at him in astonishment, "Why?" Yan Junze smiled, "There are some things I'd rather not say, but once I tell you her secret, you might be too frightened to even think of anything else." Li Man's heart shuddered at his words, and she quickly bowed her head to continue tidying up the bedding, asking no further questions. Yan Junze had no choice; if he didn't make things clear now, his parents would probably cling to their fantasies, making it awkward for everyone. Soon, the bedding was arranged for three people, as intended. Having finished washing the dishes, Xiang Er sat with Li Man on the living room sofa; with his wife by his side, Yan Daguo spoke much less boisterously. Yan Junze also sat with them for a while, but as he saw the sky outside had completely darkened, he turned to his mother and asked, "Mom, where are the incense and candles I asked you to buy on your way back?" "In the drawer." Li Man got up, opened the drawer, and took out two thick, large white candles. Yan Junze took them and said, "Everyone, please stay inside for a while, and don't go anywhere. I'll be back soon." At the door, he changed his shoes and stepped outside; he quickly returned, however, muttering to himself, "How come there's a moon? Xiang Er, hand me that larger black umbrella inside there." He gestured towards a cabinet beside the dining table. Xiang Er went over, opened the cabinet, and quickly brought out a black umbrella, the type specifically used by Huang Feihong in fights, and handed it to Yan Junze. Yan Junze took the umbrella, stepped back out, and opened it as he entered the corridor, departing slowly with the umbrella in hand. Ku Zai watched this scene in astonishment, peering through the window until Yan Junze's silhouette vanished. Yan Daguo waved his hand dismissively, "Let him be, Ze is always so secretive about everything. Now, where were we? Ah, I was even younger than you are now when I started my first job..." Ku Zai shivered, forcing a smile more agonizing than crying and pretending to listen attentively, while inside only four words surfaced in his mind. "This is so hard." ... After descending the stairs and turning a corner on the ground floor, Yan Junze stood before a door leading to the underground garage. As he opened the door, he collapsed the umbrella and leaned it against the wall behind him, then walked down the slightly damp steps. Everything around him was still so familiar; the garage wasn't very full, and the dim lighting made it impossible for anyone to see him if he stayed close to the walls. He made his way to a utility room with ease. The small door to the room was ajar, revealing nothing but darkness inside. Yan Junze pushed the door open further, felt around for a switch and pressed it, but no light came on—probably a burnt-out bulb. Taking out a flashlight, he shone the beam inside and called out, "Aunt Mei, Aunt Mei, I'm back!" Soon, rustling sounds came from the back room, and about five to six seconds later, a familiar head floated in the doorway of the inner room, smiling—it was Aunt Mei. Yan Junze was no stranger to this disembodied head, nor to the blood thread that hung from the neck. This time, however, the other end of the blood thread was not attached to a body but was torn, the break not red but pitch black, as if tainted with venom. Yan Junze entered the room and approached the doorway. With the flashlight illuminating the ground, he immediately turned to look at Aunt Mei's headless body and gasped in shock. Her once obese body was ragged and riddled with holes. Black bugs he had never seen before were crawling out in droves from the neck's severed edge, nearly covering the entire body. It was clear that these bugs were devouring Aunt Mei's body. Not only was her body infested with black bugs, but they were also swarming the floor around her. A black bug crawled towards Yan Junze's foot. He promptly stomped on it, only to feel as if he had kicked something hard. He lifted his foot, and there the bug was, unharmed and still moving, while his foot throbbed with a dull pain.
