Lin Xiu transmigrated into a parallel world only to find himself in the midst of a sudden zombie apocalypse. Trapped inside the university’s interest club storage room, he gripped a fruit knife in panic as zombies pounded on the door. Scanning the cosplay props and club items, he discovered that every object in the room bore the label “Can be Synthesized.” By touching a wooden prop Tang Saber to the fruit knife, he activated the system for the first time. The two items merged into a luminous, razor‑sharp Tang Saber, and he immediately killed a zombie that broke through the door. The system bound, awarding him 1 Synthesis Coin and sending a beginner gift pack.With the gift pack he gained Melee Weapon Mastery and 50 Synthesis Coins. The skill made the Tang Saber feel like an extension of his own body, and he understood that the synthesis function could also upgrade equipment. His first goal was to reach his dormitory and reunite with his three roommates, Haozi, Er Gouzi, and Lao Jiang. Despite the chaos, the dormitory building was safer because the teaching buildings were more heavily infected. Fighting his way through the sports field, Lin Xiu beheaded zombie after zombie, collecting more coins. When he reached the dormitory gate, his roommates – all calm and already having cleared the building’s zombies – let him in. The four were safe for the moment.Lin Xiu then experimented with the system by synthesizing a can of Blue Bull and a bottle of Lei Bi. Spending 30 Synthesis Coins, he obtained a bottle of Body Potion (Excellent) that could reshape the body and slightly increase all attributes, though only one bottle per person. He drank it and immediately felt his physique improve, becoming leaner and stronger. When he showed his new form to the three, they were stunned. Lin Xiu then synthesized three more bottles of Body Potion in front of them, revealing that he had awakened an ability. The three drank the potion and also underwent transformation, shedding excess weight and gaining enhanced physical capabilities.Now equipped with stronger teammates, Lin Xiu decided to venture outside to gather more resources and Synthesis Coins. Er Gouzi had a high‑quality Iron Man armor costume, a heavy metal shell weighing nearly a hundred pounds. Lin Xiu put it on and, thanks to his improved strength, found it manageable. With the armor and his Tang Saber, he stepped out of the dormitory, facing the zombies that had gathered at the gate. He began clearing the area systematically, decapitating zombies and earning coins. The system awarded him the title “Decapitation Master,” which tripled the coin gain from decapitation kills.While clearing near the canteen, a loud explosion sounded from the back. Lin Xiu rushed over and found six male students and three female students from his Anime Club trying to escape by climbing ropes to the second floor. The explosion had been a homemade bomb using machine oil, indicating resourceful survivors. Lin Xiu opened his faceplate, shouted that he was human, and told them to keep climbing while he held off the pursuing swarm. He stood at the entrance, cutting down zombies with single strokes, buying time for the survivors to reach safety. The excerpt ends as he rescues them, with his immediate goal being to secure the area and continue strengthening himself and his group in the zombie‑ravaged campus.
