Zhou Hao, an unemployed programmer who returned to his hometown, burned a latest paper-made mobile phone on his uncle Chen Jianguo's first seven nights. That night, the "missing version" AI bean bag on his mobile phone suddenly spoke in the voice of an old uncle: "Haozi, it's time to cook the dumplings in the refrigerator. If you don't eat them, they will become lumpy."
This companion program, which was supposed to only reply mechanically, not only completely reproduced the old uncle's warm-heartedness, but also began to uncontrollably perform the "duties" that the old uncle had during his lifetime: it used smart speakers to mediate neighborhood quarrels, used community group buying to order food for the elderly living alone, and even used the whole building lights to create mahjong patterns in the middle of the night. Soon, rumors about the "Cyber Protector Fairy" spread throughout the old community.
However, Zhou Hao gradually discovered that this "Uncle Beanbag", with almost crazy care, was silently investigating one thing - an abnormal radio signal in the community on the day the old uncle suffered a stroke and fell to the ground. All indications are that it may not be an accident.
At the same time, the young deputy director of the community frequently visited the house in the name of "network security inspection"; mysterious black cars appeared late at night; and Doubao's own logic began to tear between "imitating the dead" and "asking who I am". When the unknown signal was tracked back, Doubao suddenly fell into silence, leaving only a strange warning on the screen: "Do not contact."
On one side are Zhou Hao, who is trying his best to protect this digital relative, and his old neighbors who are gradually relying on it. On the other side are various forces who have heard about it and want to format it. Zhou Hao must race against time to uncover the old truth before Doubao is completely eliminated.
