Li Li is a chubby tabby cat living on a school campus, secretly cared for by the school’s guidance director. He is a clever cat who understands human behavior and uses his cute appearance to get food from various feeders, including a group of graduating girls: Shan Shan, Tan Birong, and Xiao Linger. One day, these girls attempt to adopt Li Li, mistakenly believing he is a stray. They lure him with goose liver canned food, and Li Li, after putting on an act of friendliness, realizes their intention and tries to escape. However, he trips and is caught by the three, who stuff him into a pet carrier. Just as they are about to leave, the guidance director arrives and sternly stops them, revealing that Li Li is the school’s cat and is officially taken care of. He frees Li Li and sends the girls away. The guidance director then privately feeds Li Li a cat treat, scolds him for his carelessness, and advises him to be careful. After the director leaves, Li Li climbs a tree, where he suddenly hears an electronic voice announcing the loading of the “Comprehensive Network” at 100%. The system greets him as a player and asks for a name; Li Li replies with his own name. The system presents five paths to improve his strength: Cultivation, Beastman, Technology, Faith, and Superpower. Li Li considers each option and decides on the Superpower path because it seems the most flexible and least demanding. After confirmation, the system analyzes his body and offers five potential superpowers: Hard Skin, Greedy Giant Stomach, Sharp Roar, Swift as the Wind, and Minute Capture. Li Li chooses Greedy Giant Stomach, which allows him to gain energy and grow stronger by eating massive amounts of food. The system congratulates him and informs him that he has seven days to prepare for his first journey to another world. It explains that the Comprehensive Network does not assign missions, so players can act freely, but they must always protect their lives because death in another world is permanent. Additionally, other worlds are not lawless, and players may encounter other network players there. Li Li, worried yet excited, decides to use his remaining time to eat as much as possible to develop his ability. He immediately heads to the girls’ dormitory to beg for food, knowing that female college students cannot resist a cute cat. Meanwhile, the three girls walk away discussing their failed attempt, but Xiao Linger is pleased with the increased followers from her live broadcast. The story returns to Li Li at the girls’ dormitory gate, where the dormitory aunt blocks his entry, stating that pets are not allowed. The narrative ends with Li Li facing this obstacle. The core storyline establishes Li Li’s transformation from a clever school cat into a system-enhanced being with the potential to travel across worlds, setting the stage for his future adventures and the challenges of preparing within a limited time frame. The key elements include his identity as a non-stray cat, the encounter with the girls, the intervention of the guidance director, the acquisition of the Comprehensive Network, and his chosen superpower that hinges on consuming large quantities of food. The immediate goal is to eat and grow stronger before the seven-day deadline.
