During the initial year of Zhenguan's rule, there were three opposing factions led by Tianxuan, Daxing Fangshu, and extraterrestrials who had taken control of two territories. Luoling City had experienced an unusual earthquake a few years earlier, which accidentally created a path called Chang'an Huan Jie, connecting two worlds. To avoid turning both cities into a battlefield, aliens who did business in both places used the road secretly. Gu Shaoning, a teenage human, unexpectedly encountered Chang'an Magic Street and befriended the extraterrestrial residents. This serendipitous event changed his humdrum destiny and unearthed the enigma of Chang'an Fantasy Street. As Gu's fate unfolds, he becomes entangled in the ancient sects and extraterrestrial race war.
