Volckano is proud to release the official trailer for 败走麦城 ( Bài Zǒu Màichéng ), an original AI-generated short film that mixes time travel with one of the most famous tragedies in Chinese history. The story: A modern-day man stumbles into a time rift and lands in 219 AD, right in the middle of the Three Kingdoms period. He knows exactly what is about to happen — Guan Yu , the unbreakable God of War and sworn brother of Liu Bei, is about to lose everything. After years of holding Jingzhou, Guan Yu pushes north to besiege Fancheng. He wins battle after battle. Then Sun Quan's general Lü Meng stabs him in the back, seizing Jingzhou while Guan Yu is away. Trapped between Wu from the south and Wei from the north, with fewer than a dozen cavalry left by his side, Guan Yu retreats to a small mountain fortress called Maicheng. No rescue comes. He is ambushed, captured, and executed. His head is sent to Cao Cao in a box. He is 58 years old. The man from the future knows all of this. He has one chance to change it. Why this story: 败走麦城 is a phrase still used in Chinese today — it means to suffer a humiliating defeat after a long run of success Guan Yu is not just a historical figure. He is worshipped across China, Southeast Asia, and Chinese communities worldwide as the God of War, God of Brotherhood, and the patron saint of both police and triads — a rare figure respected by everyone The tragedy at Maicheng was not just a military loss. It was the beginning of the end for Liu Bei's dream of restoring the Han dynasty. Zhang Fei died shortly after. Liu Bei died on campaign trying to avenge them both. The trailer was produced entirely using AI video generation tools as part of Volckano's ongoing AI filmmaking work. Every shot — the ancient battlefields, the fog-covered mountain pass at Maicheng, the flickering torchlight, the moment Guan Yu realizes no help is coming — was built from prompts, reference images, and post-production color work. This is the kind of story AI filmmaking was made for: epic in scale, emotionally loaded, and impossible to shoot on a small budget the traditional way.
