Yun Heng, the former guardian, is now the most fashion-savvy stylist under the urban night sky. He uses scissors and inspiration to shape his appearance, and he also uses secrets to guard the balance of the city. But when mysterious forces use fashion as a weapon to penetrate people's hearts and exaggerate the fire of desire, Yunheng has to regain his fighting instinct in the neon lights and shadows. He is both a guardian and a leader - walking between haute couture shows and underground clubs, using beauty as a shield and faith as a blade. The core conflict of the story is: protection and change, tradition and new trends. Yunheng must make a choice between protecting the soul of the city and challenging his own limits. Fashion is not just an appearance, but also a contest of strength; and his battle will ultimately determine the future style of the city.
