I can rewind time to prevent death

The middle-aged woman, apparently accustomed to being scolded at home, had no thought of talking back. She ran off, silent as a cicada in winter, picked up the teapot, and hurried into the kitchen. The sound of water pouring soon followed as she quickly dumped all the hot, steaming tea into the kitchen sink. "Is it all poured out?" the man yelled from the main room. "It's all poured out, not a drop left," the woman hastily responded, afraid that the man would come to check. She turned her head toward the kitchen door and saw that he had not entered. But in the moment she turned her head, from among the tea pouring down the sink drain, a finger emerged, its fingernail broken and cracked, the dried blood caked on the pad. However, as the tea crazily poured into the drain, the finger only stuck out for about a second before it disappeared with the flowing tea deep into the drain. The woman turned back around, seeing nothing, but her fear was directed at the man outside. She quickly put the teapot back in its place, not daring to turn on the tap to clean it. The man's voice rose again from outside: "Once it's poured out, come clean up the broken teacup on the floor. You're always dragging your feet. Remember, don't open the faucet. There shouldn't be a single drop of water visible in the house." "Okay," the woman replied. She walked into the living room, squatted down, picked up the larger pieces of the broken teacup, and tossed them into the nearby trash bin. As she squatted down again to pick up other larger pieces, a sharp pain suddenly shot through her finger. Her arm trembled, and she brought it close to her face for a look, only to discover that her index finger was bleeding from a cut caused by a shard. "Stupid wife, don't we have a broom in the house? You're utterly foolish!" Ever since she had come out of the kitchen, the man had been watching her, and seeing the state she was in, not only did he show no concern, but he also berated her angrily. Without a word, the woman sucked on her index finger for a moment, not even thinking to dress the wound right away. Instead, she took a broom and dustpan back to the living room and swept up the rest of the teacup shards from the floor. After returning the broom to the kitchen, she noticed that her index finger was bleeding again, the blood about to drip down. Instinctively, she moved to turn on the kitchen tap to rinse the wound, but as her hand approached the sink, she suddenly jerked back, remembering the prohibition against using the tap. She quickly left the kitchen and headed to the bedroom. While walking, she sucked on her finger again. The man watched her enter the bedroom from the corner of his eye, then turned his attention back to the television screen that was still on. After a while, the middle-aged man picked up the mobile phone beside him, glanced at the string of 4747 numbers he had dialed, and heaved a sigh. After the woman entered the bedroom, she rifled through her belongings looking for a bandage, but found nothing. She remembered that there might be one in the living room cabinet, but she did not dare search for it in front of her husband lest she gets scolded again. After a moment's consideration, she decided against looking for it altogether, simply sitting on the edge of the bed and sucking on her index finger. At that moment, the blood from the wound had stopped flowing. Shortly after she had put her finger in her mouth, her tongue suddenly felt something sharp. She pulled her finger out to take a closer look. There, at the tip of her index finger, was a black hair sharp poking out from the wound—it was this that her tongue had touched. Upon closer inspection, it seemed as though two more hair tips were trying to emerge from the wound. Knock, knock, knock—the sound of knocking came. "Go open the door!" the man in the living room yelled, even though he was closest to the door, he was reluctant to move. The woman said nothing, walked out of the bedroom, came to the living room door and, instead of opening it immediately, asked, "Who is it?" "Exorcist," came the voice of a young man from outside. The woman was startled. The man sitting on the sofa was overjoyed, immediately rising from the sofa with excitement in his voice, "Open the door, open the door quickly, the Exorcist Master has arrived!" The door opened, and Yan Junze and Xiang Er stood outside, peering in. "Is this Sun Changbiao's home?" The middle-aged man had already stood up and scuttled over in his slippers, saying eagerly, "It is, I am Sun Changbiao. Exorcist Master, please come in, come in!" Yan Junze and Xiang Er stepped into the house one after the other. Upon seeing Xiang Er, Sun Changbiao's eyes lit up, lingering greedily upon her for a few seconds before finally turning to Yan Junze. "Master, the strangeness in my house is terrible. You must help us, please rid us of it quickly," Sun Changbiao said. Yan Junze gave him a glance. To be honest, he very much disliked the way this fellow eyed Xiang Er, Sun Changbiao's wife was likely there, but he looked at Xiang Er with no consideration whatsoever, as if his own wife did not exist. It's normal for a man to appreciate a beautiful woman, but the greediness in Sun Changbiao's eyes was such that, even in the presence of his own wife, it seemed as if he wanted to devour Xiang Er right then and there. Just from the first impression, Yan Junze had already begun to dislike this man. "Tell me exactly what is the situation," Yan Junze said. Immediately, Sun Changbiao nodded earnestly: "Master, please sit. I will tell you all about it. Now that you are here, I can finally relax a little." Sun Changbiao had not expected the Exorcist to arrive so quickly. After Yan Junze and Xiang Er were seated, he said to his wife, "What are you standing around for, go make some tea!" His words were followed by a sharp pause, "No, no, no, no need for tea..." Then with a forced smile, he turned to Yan Junze and Xiang Er, "Sorry about that. The strangeness in our house is related to water. We can't have any water here; as soon as water appears, the strangeness shows up."
