Late at night, the most prosperous Flower Street in R City was filled with bright lights, and the sky was brightly illuminated by neon lights. Yang Guang was patrolling the place with his brothers as usual. After patrolling for a while, he came out to smoke a cigarette. Unexpectedly, he would be in the back alley after a while. I picked up a young man with blue eyes who was beaten and covered in blood. The young man had an astonishingly beautiful appearance and abilities beyond ordinary people. His life experience was shrouded in mystery. As Yang Guangde unintentionally got involved, a huge conspiracy beyond his cognition gradually revealed the tip of the iceberg. What is the true identity of the young man, and is Yang Guang just the top nurse guard like his apparent identity? There are many shadows, and what he sees may not be entirely the truth.
