Shu Xiaohui was a human survivor in an underground air-raid shelter after the Tart Tribe invaded Earth. The Tart Tribe, a brutal cosmic civilization, deployed semi-mechanical gene organisms to eliminate all life forms for planetary resources. Shu Xiaohui was on a scavenging mission when a scorching white light from an ancient ruin struck him, transforming him into a tiny hamster with light silver-gray fur on his back and a white belly. He retained his human consciousness and gained a small space for storing items, but lost all combat ability and physical strength. He could burrow through crevices and used this to escape semi-mechanical creatures and return to the shelter.In the shelter, he lived discreetly in a hollow cavity near the roof, building a nest from stolen medical cotton wadding. He sustained himself by exchanging airdrop weapon supplies for small amounts of food from the shelter's depot, taking only dried fruits, corn, and carrots that his small body could tolerate. He learned from a salvaged radio that the Tart Tribe had been destroyed, but their semi-mechanical creatures remained active with upgraded self-evolution and tracking systems. The white light had awakened special abilities in some humans, allowing them to bond with battle pets. A new city was being rebuilt in Province Z within Province X, offering hope for survivors.Shu Xiaohui suspected he might have a spirit-word ability, as his thoughts briefly caused a volley of ion guns to hit a specific spot, but he lacked confidence in his powers. Feeling lonely and vulnerable in his hamster form, he decided to travel to the new city for better survival prospects. He joined a convoy led by Li Chitian, a powerful survivor with a bull battle pet who had merged with the animal for enhanced strength. The convoy was large and included a bus packed with survivors, making it an obvious target for semi-mechanical creatures despite Li Chitian's bravado.During the journey, the convoy was attacked by semi-mechanical creatures. Shu Xiaohui hid in a truck bearing airdropped firearms, observing the chaos. Li Chitian used his merged form to fight, but his reckless leadership attracted more enemies. They encountered Chen Chengduo and his team, who possessed advanced technology and battle pets including an eagle, a leopard, and a crocodile. Chen Chengduo demonstrated superior strategy and combat skills, urging survivors to scatter and take cover rather than cluster as Li Chitian ordered. Chen Chengduo sensed a mysterious connection with Shu Xiaohui, hearing faint squeaks and feeling a pull during mental attempts to communicate, mistakenly believing the hamster might be his battle pet.Shu Xiaohui felt an unfamiliar familiarity toward Chen Chengduo, a sense of closeness that drew him toward the man. As the battle intensified, Li Chitian blockaded the underground garage entrance with thrown cars, trapping survivors above ground. Shu Xiaohui, hidden nearby, angrily voiced his wish for the cars to be hit by ion guns, and a volley struck the blockade, confirming his latent spirit-word ability. This moment stunned him but also revealed a potential path to survival. Chen Chengduo noticed the movement of a small creature but dismissed it amidst the fighting.Shu Xiaohui prioritized survival and the goal of reaching the new city, where he hoped to understand his transformation and abilities. The semi-mechanical creatures continued to press the attack, but Chen Chengduo's team provided temporary relief. Shu Xiaohui remained in hiding, aware of his extreme vulnerability but also a growing resilience. He had gone from a helpless survivor in an air-raid shelter to a being with emerging powers, facing the apocalypse with a mixture of fear and determination. The journey toward the rebuilt city represented both a physical destination and a symbolic hope for a new beginning, as Shu Xiaohui navigated the dangers of a world still under siege by the remnants of the Tart Tribe's invasion.
