Shen Youning squatted at the door of the rental house, still holding the neighbor's unrepaired rice cooker in his hand. Three-year-old Shen Xiaohe was sitting on the steps, holding the orange cat Nian Gao in his arms, and said seriously: "Dad, Nian Gao said it wants to eat fish." Wang Guilan's voice boomed from the alley: "Shen Youning! The water dripping from your air conditioner's outdoor unit has soaked my quilt all over!" Before he could explain, his cell phone vibrated - there was a message from the landlord Zhao Lei: "The rent will be increased at the end of the month, and we will move out without rent." Late at night, he stared at the old refrigerator that had been repaired three times, and suddenly saw a line of small transparent words appearing on the panel: "Do you want to turn on smart interconnection? It consumes 5% of today's physical energy." He clicked to confirm. The refrigerator started defrosting automatically, the washing machine separated dark colors from light ones, and even my daughter's broken toy dog blinked and stood up. The next day, Wang Guilan came to make trouble again, saying that he had stolen electricity. In front of the entire alley, Shen Youning used his mobile phone to put all the home appliances into standby mode, and the real-time energy consumption was displayed as zero. The eyes of the onlookers changed from suspicion to shock. Shen Xiaohe tugged on the corner of his clothes: "Dad, Nian Gao said he likes his current home." Shen Youning touched his daughter's head and was about to laugh when his wrist stung. System prompt: 90% physical exhaustion, please rest immediately. And he saw the courier at the alley carrying a huge new TV and walking to the empty room next door. Who are the new neighbors? What he doesn't know is that when all the home appliances start to respond to him, some things also start to penetrate through the power grid and reversely penetrate into his life.
